Description

本発明は、作物を圃場から引き抜き搬送し、畝溝を埋めながら走行する根菜類収穫機に関するものである。   The present invention relates to a root crop harvester that pulls and conveys a crop from a field and travels while filling a ridge.

従来の根菜類収穫機としては、機体前部に畝上の土を畝溝に寄せる溝埋め装置を設け、左右一方の走行クローラが畝溝を走行する際に機体が傾斜することを防止する技術が存在する。(特許文献1、2)   As a conventional root crop harvester, a ditch filling device that brings the soil on the gutter to the gutter groove at the front of the machine body, and a technique to prevent the machine body from tilting when one of the left and right traveling crawlers runs in the gutter groove Exists.

しかしながら、特許文献1及び2に記載された根菜類収穫機は、溝埋め装置の昇降機構を引抜搬送装置の昇降機構から独立させた構成としているので、圃場端で旋回するときや非作業状態とするときは、溝埋め装置と引抜搬送装置を別々に操作して圃場面から上方に離間させる必要があり、作業能率が低下するとともに、旋回前の操作工数が多く、操作性が悪くなる問題がある。   However, the root vegetable harvesting machine described in Patent Documents 1 and 2 has a configuration in which the lifting mechanism of the ditch filling device is made independent of the lifting mechanism of the pulling and conveying device. When doing this, it is necessary to operate the groove filling device and the pulling / conveying device separately to separate them upward from the field scene, which reduces the work efficiency and increases the man-hours before turning, resulting in poor operability. is there.

The ditch is not filled enough, and the aircraft tilts toward the groin, losing crops or removing the foliage of the crops, and the operator must pull out the ginseng and remove the foliage. There is a problem that efficiency decreases.

そして、機体の前側には作物を収容した収容部材を積載する積載台が設けられていないので、収容部材の積載量が少なく、頻繁に収容容器を交換する必要があり、作業能率が悪くなる問題がある。   And since there is no loading platform on the front side of the machine to load the storage members that contain the crops, there is a small load on the storage members, and it is necessary to frequently change the storage containers, resulting in poor work efficiency. There is.

本発明は、これらの問題を解消しようとするものである。   The present invention seeks to eliminate these problems.

It is. At this time, if the left and right collars 124 and 124 are configured not to be slidable in the left and right direction along the cylinder support shaft 123, the predetermined spacing in the left and right direction between the left and right collars 124 and 124 is prevented from changing.

そして、後述する引継搬送部Eを構成する前後の残葉処理フレーム72a,72bのうち、機体前側の残葉処理フレーム72aを前記左右の支持プレート122,122よりも機体後側に設け、該前側の残葉処理フレーム72aにゴムや合成樹脂等の弾性体で構成する保護マット125の後端側をピンやボルト等の固定部材125a…で取り付ける。該保護マット125を前側の残葉処理フレーム72aに固定部材125a…を介して取り付ける位置は、前側の残葉処理フレーム72aの上端部よりも下方位置とする。   Of the remaining leaf processing frames 72a and 72b before and after the take-up conveyance unit E, which will be described later, the remaining leaf processing frame 72a on the front side of the machine body is provided on the rear side of the machine body with respect to the left and right support plates 122 and 122. The rear end side of the protective mat 125 made of an elastic body such as rubber or synthetic resin is attached to the remaining leaf processing frame 72a with fixing members 125a. The position where the protective mat 125 is attached to the front remaining leaf processing frame 72a via the fixing members 125a... Is lower than the upper end portion of the front remaining leaf processing frame 72a.

該前側の残葉処理フレーム72aのうち、少なくとも保護マット125の左右幅と略同じ左右幅に亘って、上下高さが低くなる切欠部72zを形成すると、保護マット125から残葉処理部Eに移動する人参が接触する部材が無くなるため、移動中に人参が傷付くことが防止でき、人参の商品価値が向上する。   When the notch 72z having a lower vertical height is formed over at least the left and right width of the front-side remaining leaf processing frame 72a substantially the same as the left and right width of the protection mat 125, the protection mat 125 forms the remaining leaf processing portion E. Since there is no member in contact with the moving carrot, the carrot can be prevented from being damaged during the movement, and the product value of the carrot is improved.

さらに、該保護マット125を左右のカラー124,124の上側を通過させて機体前側に延ばし、該左右のカラー124,124に接触する位置で下方に向けて屈曲させる。また、該保護マット125の前端部には、保護マット125の前端側を下方に向けて引き下げる引下げウェイト126を取り付けて、昇降油圧シリンダ23に搬送途中の人参から落下してくる泥土が接触することや、長さの長い人参が昇降油圧シリンダ23に接触して破損することを防止する防護装置127が構成される。該引下げウェイト126は、保護マット125が捲れ上がらない程度の質量を有していれば、どのような材質で構成してもよい。   Further, the protective mat 125 passes through the upper sides of the left and right collars 124 and 124 and extends to the front side of the machine body, and is bent downward at a position in contact with the left and right collars 124 and 124. Further, a lowering weight 126 for lowering the front end side of the protective mat 125 downward is attached to the front end portion of the protective mat 125 so that mud falling from the carrots in the middle of conveyance contacts the lift hydraulic cylinder 23. In addition, a protective device 127 is configured to prevent a long carrot from coming into contact with the lifting hydraulic cylinder 23 and being damaged. The pulling weight 126 may be made of any material as long as it has a mass that prevents the protective mat 125 from rolling up.

なお、上記構成とした防護装置127において、保護マット125は前側の残葉処理フレーム72aから左右のカラー124,124の上側に向けて、円弧(U字形)を描く屈曲部Wを形成するものとする。この屈曲部Wは、引下げウェイト126の質量によって変更される。   In the protective device 127 configured as described above, the protective mat 125 forms a bent portion W that draws an arc (U-shape) from the front-side remaining leaf processing frame 72a toward the upper side of the left and right collars 124, 124. To do. This bent portion W is changed by the mass of the pull-down weight 126.

このとき、図10(a)(b)で示すように、引下げウェイト126を重り支持軸126aと、該重り支持軸126aに着脱自在に設ける複数の重り126b…で構成すると、作業者は容易に引下げウェイト126の質量を変更して、保護マット125の張りの強弱を変更することができ、人参が保護マット125に衝突してもいっそう破損しにくくなるため、人参の商品価値が維持される。   At this time, as shown in FIGS. 10 (a) and 10 (b), if the weight 126 is composed of a weight support shaft 126a and a plurality of weights 126b provided detachably on the weight support shaft 126a, the operator can easily perform the operation. The tension of the protective mat 125 can be changed by changing the mass of the pull-down weight 126, and even if the carrot collides with the protective mat 125, it is more difficult to break, so that the commercial value of the carrot is maintained.

また、該引抜搬送装置24の前方に人参の茎葉部を引き起こす縦引起し装置25と、該縦引起し装置25が引起した茎葉部を掬い上げる横引起し装置26と、該横引起し装置26の前部に設ける分草杆27と、前記エンジン7の駆動力で回転するシャフト32の回転によって振動する振動フレーム33に取り付けた人参の左右の土を振動によって解す左右振動ソイラ34,34とを設ける。   Also, a vertical elevating device 25 that causes ginseng foliage in front of the drawing and conveying device 24, a horizontal elevating device 26 that scoops up the foliage raised by the vertical elevating device 25, and the horizontal elevating device 26. And a left-and-right vibration soyers 34 and 34 for solving the left and right soils of carrots attached to a vibration frame 33 that vibrates by the rotation of the shaft 32 rotated by the driving force of the engine 7 by vibration.

そして、前記引抜搬送通路Rの下方で且つ左右の角パイプ20a,20aの左右間に、左右方向に複数の尻尾通過溝35c…を形成したカバーケース35bを設け、該カバーケース35bの内部に駆動モータ(図示省略)から駆動力を受けて回転する尻尾切断刃35aを設けて引抜搬送装置24で搬送中の人参のひげ根を切断する尻尾切装置35を構成することによって、収穫部Cが構成される。   A cover case 35b having a plurality of tail passage grooves 35c formed in the left-right direction is provided below the pull-out conveyance path R and between the left and right of the left and right square pipes 20a, 20a, and is driven inside the cover case 35b. The harvesting section C is configured by providing a tail cutting blade 35a that rotates by receiving a driving force from a motor (not shown) and forming the tail cutting device 35 that cuts the carrot root of the carrot that is being transported by the pulling and transporting device 24. Is done.

なお、該尻尾切装置35の後部には、前記防護装置127を構成する保護マット125のうち、引下げウェイト126によって略垂直に下方に垂れ下げられる前端部側を配置し、尻尾切装置35を通過した人参を受け止める構成とすると、尻尾切断刃35aの回転力により押し出された人参の姿勢が乱れることが防止され、搬送精度が向上する。   A rear end portion of the protective mat 125 that constitutes the protective device 127 is disposed at the rear portion of the tail cutting device 35 so as to be hung down substantially vertically by the pulling weight 126, and passes through the tail cutting device 35. If it is configured to receive the carrot, the posture of the carrot pushed out by the rotational force of the tail cutting blade 35a is prevented from being disturbed, and the conveyance accuracy is improved.

上記構成により、機体前側に分草杆27を備える横引起し装置26と、縦引起し装置25を設けることによって、圃場に倒伏した人参の茎葉を掻き上げながら収穫作業ができ、収穫する人参の視認性が向上するので引き抜き位置が合わせやすく、作物の抜き残しが減少するため作業能率が向上する。   With the above configuration, by providing the horizontal elevating device 26 having the weed pod 27 and the vertical elevating device 25 on the front side of the machine body, the harvesting operation can be performed while picking up the ginseng stems and leaves that have fallen on the field. Since the visibility is improved, the extraction position can be easily adjusted, and the work efficiency is improved because the crop residue is reduced.

また、人参に左右振動ソイラ34,34等が接触して傷つくことを防止できるので、人参の商品価値が向上する。
そして、ハンドル29を回すと上下伸縮する伸縮ロッド30の下端部にゲージ輪31を設けたことによって、ゲージ輪31を圃場面に接地させるとそれ以上引抜搬送装置24が下降しなくなるので、操縦者の操縦ミスや予期せぬ地面の凹凸によって引抜搬送装置24の下端部が圃場面に接触して破損することが防止される。
Further, since the left and right vibrating soilers 34, 34 and the like can be prevented from being damaged by the carrot, the product value of the carrot is improved.
Then, by providing the gauge ring 31 at the lower end of the telescopic rod 30 that expands and contracts up and down when the handle 29 is turned, if the gauge ring 31 is brought into contact with the field scene, the pulling and conveying device 24 will not be lowered any further. It is possible to prevent the lower end portion of the pulling / conveying device 24 from coming into contact with the field scene and being damaged due to an erroneous operation or unexpected ground irregularities.

そして、機体フレーム9と左右横軸21を回動支点として上下方向に回動自在な回動フレーム20とを昇降油圧シリンダ23で連結し、昇降油圧シリンダ23を操縦部Bの昇降操作レバー14を操作することによって伸縮させる構成としたことによって、昇降操作レバー14の操作により収穫部C全体の上下高さを調節することができるので、収穫部Cの引抜搬送始端部の位置を上下方向に調節しするとともに圃場に植生する人参の適切な引き抜き高さに合わせて引抜搬送始端部の位置調節を行え、人参の抜き残しが防止されるので作業能率が向上する。   Then, the body frame 9 and the pivot frame 20 that is pivotable in the vertical direction with the horizontal axis 21 as a pivot point are connected by a lift hydraulic cylinder 23, and the lift hydraulic cylinder 23 is connected to the lift control lever 14 of the control unit B. Since the height of the harvesting part C can be adjusted by operating the elevating operation lever 14 due to the configuration in which it is expanded and contracted by operation, the position of the pulling and conveying start end of the harvesting part C is adjusted in the vertical direction. At the same time, the position of the pulling conveyance start end can be adjusted in accordance with the appropriate pulling height of the carrots to be vegetated on the field, so that the remaining carrot is prevented, so that the work efficiency is improved.

また、旋回時に収穫部Cを上昇させておくと、収穫部Cの下端部が圃場に接触しにくくなるため、旋回動作がスムーズに行われて作業能率が向上する。
さらに、昇降油圧シリンダ23の前後及び上方を覆う軟質部材で構成する保護マット125を設けたことにより、引抜搬送装置24で搬送中の人参にから降って来る泥土や水等が昇降油圧シリンダ23に付着することを防止できるので、昇降油圧シリンダ23が破損することや、作動不良を起こすことが防止されるため、耐久性や操作性が向上する。
Further, if the harvesting section C is raised during turning, the lower end of the harvesting section C is less likely to come into contact with the field, so that the turning operation is performed smoothly and the work efficiency is improved.
Furthermore, by providing a protective mat 125 made of a soft member that covers the front and rear and the upper side of the lifting hydraulic cylinder 23, mud, water, etc. falling from the carrots being transported by the pulling and transporting device 24 to the lifting hydraulic cylinder 23. Since adhesion can be prevented, the lifting hydraulic cylinder 23 is prevented from being damaged or malfunctioning, so that durability and operability are improved.

また、昇降油圧シリンダ23の前部を下方に向かって略垂直方向に垂らしていることにより、人参の上下長さが長いものであっても、その人参の下部側を保護マット125が受け止めることができるので、人参が昇降油圧シリンダ23や左右の支持プレート122,122に接触することが防止され、人参が傷付くことがなく、商品価値が向上する。   In addition, by hanging the front part of the lifting hydraulic cylinder 23 downward in a substantially vertical direction, the protective mat 125 can catch the lower part of the carrot even if the carrot has a long vertical length. Therefore, the ginseng is prevented from coming into contact with the elevating hydraulic cylinder 23 and the left and right support plates 122, 122, the carrot is not damaged, and the commercial value is improved.

そして、保護マット125の前端部に引下げウェイト126を設けて下方に向けて引き下げ、後部側を残葉処理フレーム72aに固定したことにより、保護マット125の撓み幅を大きく取ることができるので、保護マット125が抵抗となって接触した人参を傷つけることが防止され、いっそう人参の商品価値が向上する。   Since the lower weight 126 is provided at the front end portion of the protective mat 125, the weight is lowered downward, and the rear side is fixed to the remaining leaf processing frame 72a, the bending width of the protective mat 125 can be increased. The mat 125 is prevented from being damaged and damaging the carrots that come into contact with it, and the product value of the carrots is further improved.

さらに、シリンダ支持軸123に左右のカラー124,124を回転自在に装着し、この左右のカラー124,124の上部に保護マット125を接触させる構成としたことにより、保護マット125に人参が接触して撓むときや、引下げウェイト126の重量を変更して保護マット125の前端部の上下位置を変更するとき、保護マット125にかかる摩擦抵抗を減らすことができるので、保護マット125の耐久性が向上する。   Further, the left and right collars 124 and 124 are rotatably mounted on the cylinder support shaft 123, and the protective mat 125 is in contact with the upper portions of the left and right collars 124 and 124, so that the carrot contacts the protective mat 125. Thus, when the weight of the pull-down weight 126 is changed and the vertical position of the front end portion of the protective mat 125 is changed, the frictional resistance applied to the protective mat 125 can be reduced. improves.

これに加えて、保護マット125が摩擦抵抗でその位置に留まることや、保護マット125が伸びて意図した張りに合わなくなることが防止されるので、保護マット125に接触する人参の傷付きが防止されて、商品価値が向上する。   In addition to this, the protective mat 125 is prevented from staying in its position due to frictional resistance, and the protective mat 125 is prevented from being stretched and not meeting the intended tension. As a result, the product value is improved.

また、左右のカラー124,124を左右方向に所定間隔を空けて設けたことにより、人参が保護マット125に接触する頻度の高い左右方向中央部に撓みを抑える部材が配置されない構成とすることができるので、人参が保護マット125に接触する際の撓み代が十分に確保されるため、保護マット125が十分に撓めず抵抗が強くなって人参を傷つけることが無く、人参の商品価値がいっそう向上する。   In addition, by providing the left and right collars 124 at a predetermined interval in the left-right direction, a configuration is adopted in which no member that suppresses bending is disposed in the central portion in the left-right direction where carrots frequently contact the protective mat 125. Since the bend allowance when the ginseng contacts the protective mat 125 is sufficiently secured, the protective mat 125 does not bend sufficiently and the resistance does not increase so that the carrot is not damaged, and the product value of the carrot is further increased. improves.

そして、保護マット125の前端部を引下げウェイト126で下方に引き下げ、後部側を固定部材125a…で前側の残葉処理フレーム72aに固定したことにより、保護マット125の上部側が円弧形状の屈曲部Wとなるため、人参が保護マット125に接触する際の衝撃が吸収されやすく、さらに人参が傷付きにくくなる。   Then, the front end portion of the protective mat 125 is pulled downward by the pulling weight 126, and the rear side is fixed to the front remaining leaf processing frame 72a by the fixing member 125a, so that the upper side of the protective mat 125 has an arc-shaped bent portion W. Therefore, the impact when the carrot contacts the protective mat 125 is easily absorbed, and the carrot is not easily damaged.

さらに、保護マット125を有する防護装置127を尻尾切装置35の後部の直後位置に設けたことにより、尻尾切装置35に弾き出される人参の下端部側を保護マット125で受け止めることができるので、人参が揺れて周囲の構成部材に接触して破損することが防止され、人参の商品価値が向上する。   Furthermore, by providing the protective device 127 having the protective mat 125 at a position immediately after the rear portion of the tail cutting device 35, the lower end portion of the carrots ejected by the tail cutting device 35 can be received by the protective mat 125. Is prevented from swaying and coming into contact with surrounding components, and the product value of carrots is improved.

これに加えて、人参が揺れることにより、茎葉部から根部がちぎれ、人参が残葉処理部Eよりも機体前側で落下することが防止されるため、人参に残った残葉を手作業で処理する必要がなくなると共に、機外や搬送経路外に落下した人参を拾い上げる作業が不要となるため、作業者の労力が軽減される。   In addition to this, since the carrots shake, the roots are torn off from the foliage and the carrots are prevented from falling on the front side of the machine from the remaining leaf processing part E, so the remaining leaves remaining in the carrots are processed manually. This eliminates the need to pick up the carrots that have fallen out of the machine or out of the transport path, thereby reducing the labor of the operator.

また、保護マット125の後側垂下部を固定部材125aで前側の残葉処理フレーム72aに固定したことにより、保護マット125の後端部側が昇降油圧シリンダ23に接触し、昇降油圧シリンダ23の伸縮動作を妨げることを防止できるので、引抜搬送装置24の引抜作業高さの調節が正確に行われるため、作業能率が向上する。   Further, since the rear hanging portion of the protection mat 125 is fixed to the front remaining leaf processing frame 72a by the fixing member 125a, the rear end portion side of the protection mat 125 comes into contact with the elevating hydraulic cylinder 23, and the elevating hydraulic cylinder 23 is expanded and contracted. Since the operation can be prevented from being hindered, the drawing work height of the drawing / conveying device 24 is accurately adjusted, so that the work efficiency is improved.

さらに、保護マット125の後部側が昇降油圧シリンダ23の上方を上下方向に亘って覆う構成となるため、昇降油圧シリンダ23に夾雑物が落下することを確実に防止することができるので、昇降油圧シリンダ23が破損したり作動不良を起こすことが防止され、耐久性が向上すると共に、作業性が向上する。   Further, since the rear side of the protective mat 125 covers the upper part of the lifting hydraulic cylinder 23 in the vertical direction, it is possible to reliably prevent foreign matter from falling into the lifting hydraulic cylinder 23. 23 is prevented from being damaged or malfunctioning, durability is improved and workability is improved.

次に、土寄せ部Hについて説明する。
前記機体フレーム1の前部で且つ操縦部B寄りの位置に土寄せメインフレーム201を前後方向に亘って設け、該土寄せメインフレーム201の前端部にプレート202を下方に向けて配置する。そして、該プレート202の下端部に支軸203を左右方向に向けて設け、該支軸203に中空の回動フレーム204を差し込んで配置する。該支軸203の機体左右一側端部は、機体フレーム1に設ける保持プレート205に取り付け、支軸203を保持すると共に、回動フレーム204の左右移動を規制して抜け落ちを防止する。
Next, the earth gathering part H will be described.
An earthing main frame 201 is provided in the front part of the body frame 1 and near the control part B in the front-rear direction, and a plate 202 is disposed on the front end part of the earthing main frame 201 facing downward. A support shaft 203 is provided at the lower end portion of the plate 202 in the left-right direction, and a hollow rotating frame 204 is inserted into the support shaft 203 and disposed. The left and right side ends of the support shaft 203 are attached to a holding plate 205 provided on the body frame 1 to hold the support shaft 203 and restrict the left and right movement of the rotating frame 204 to prevent falling off.

また、前記回動フレーム204の機体左右一側寄りに、畝溝に畝上の土を寄せて埋める前後一対の土寄せディスク207f,207rからなる土寄せ部材207を装着する土寄せ支持フレーム206を機体前側に向けて配置する。該土寄せ支持フレーム206は、前後方向の略中央部で機体左右一側から左右他側に向かって、且つ下方傾斜姿勢から圃場面(畝の上面)と略水平姿勢となるように屈曲させる。前記土寄せ支持フレーム206の前端部から前後方向略中央部までを、屈曲取付部206aとし、該屈曲取付部206aの上部で且つ前端側に一対の前側取付穴208a,208aを形成すると共に、屈曲取付部206aの上部で且つ後端側に一対の後側取付穴209a,209aを形成する。なお、該一対の前側取付穴208a,208aと後側取付穴209a,209aは、各々左右方向の長穴としてもよい。   Further, on the front side of the machine body, the earthing support frame 206 is mounted on the front side of the machine body. The earthing support frame 206 is mounted on the front side of the machine body. Place it facing. The earth retaining support frame 206 is bent at a substantially central portion in the front-rear direction from the left and right sides of the machine body to the left and right sides and from a downward inclined posture so as to be in a substantially horizontal posture with the farm scene (upper surface of the straw). A bent attachment portion 206a is formed from the front end portion of the earthing support frame 206 to a substantially central portion in the front-rear direction, and a pair of front attachment holes 208a and 208a are formed on the front end side of the bending attachment portion 206a and bent. A pair of rear mounting holes 209a and 209a are formed in the upper part of the portion 206a and on the rear end side. The pair of front side mounting holes 208a and 208a and rear side mounting holes 209a and 209a may be elongated holes in the left-right direction.

そして、該一対の前側取付穴208a,208aに、平面視で「へ」の字形状の前側支持アーム208を、基部側に形成されている取付穴部を前側取付穴208a,208aに合わせてボルト等の固定部材210…で連結固定して取り付ける。前側取付穴208a,208aを長穴としているときは、長穴の任意の位置と合わせてから連結固定することにより、前側支持アーム208の取付位置を調節することができる。さらに、該前側支持アーム208の端部側に前側の土寄せディスク207fを回転自在に装着する。   Then, a pair of front mounting holes 208a and 208a are fitted with a front support arm 208 having a "" "shape in plan view, and a mounting hole formed on the base side is aligned with the front mounting holes 208a and 208a. The fixing members 210... When the front side mounting holes 208a and 208a are long holes, the mounting position of the front side support arm 208 can be adjusted by connecting and fixing the front side mounting holes 208a and 208a to the arbitrary positions of the long holes. Further, a front earthing disk 207f is rotatably mounted on the end side of the front support arm 208.

また、該一対の後側取付穴209a,209aに後側支持アーム209を、基部側に形成されている取付穴部を後側取付穴209a,209aに合わせてボルト等の固定部材210…で連結固定して取り付ける。後側取付穴209a,209aを長穴としているときは、長穴の任意の位置と合わせてから連結固定することにより、後側支持アーム209の取付位置を調節することができる。さらに、該後側支持アーム209の端部側に後側の土寄せディスク207rを回転自在に装着する。   Further, a rear support arm 209 is connected to the pair of rear mounting holes 209a and 209a, and a mounting hole formed on the base side is connected to the rear mounting holes 209a and 209a by a fixing member 210 such as a bolt. Secure and attach. When the rear attachment holes 209a and 209a are elongated holes, the attachment position of the rear support arm 209 can be adjusted by connecting and fixing after matching with an arbitrary position of the elongated holes. Further, a rear earthing disk 207r is rotatably mounted on the end side of the rear support arm 209.

前記後側の土寄せディスク207rは、前側の土寄せディスク207fと略平行となる姿勢で配置すると共に、平面視では前側の土寄せディスク207fよりも機体後側に配置される。また、側面視では、前側の土寄せディスク207fと後側の土寄せディスク207rの一部がオーバーラップする配置構成とする。前後の取付穴208a,208a,209a,209aを長穴とし、前後の支持アーム208,209を位置調節可能に構成したものにおいては、前後の土寄せディスク207f,207rを各々スライドさせると、相互のオーバーラップ量が変化する。但し、前後の土寄せディスク207f,207rの位置調節量は、前後の土寄せディスク207f,207rの離間距離を最大としたときでも、外周縁部同士がオーバーラップする範囲内とする。また、土寄せ支持フレーム206と前後の土寄せディスク207f,207rは、互いに上下方向にオフセットしない配置とする。   The rear side dusting disk 207r is arranged in a posture substantially parallel to the front side earthing disk 207f, and is arranged on the rear side of the machine body from the front side dusting disk 207f in a plan view. Further, when viewed from the side, the arrangement is such that a part of the front side earthing disk 207f overlaps a part of the rear side earthing disk 207r. In the case where the front and rear mounting holes 208a, 208a, 209a, and 209a are elongated holes and the front and rear support arms 208 and 209 are configured to be adjustable in position, if the front and rear earthing disks 207f and 207r are respectively slid, The amount of lap changes. However, the amount of position adjustment of the front and rear earthing disks 207f and 207r is within a range in which the outer peripheral edges overlap even when the distance between the front and rear earthing disks 207f and 207r is maximized. Also, the earthing support frame 206 and the front and rear earthing disks 207f and 207r are arranged so as not to be offset in the vertical direction.

なお、前記前後の土寄せディスク207f,207rは半球形状(皿状)であり、凹面側を機体前側に向けて配置することにより、機体の前進に伴って畝を掘り崩し、畝溝を埋める部材である。   The front and rear earthing disks 207f and 207r are hemispherical (dish-shaped), and are arranged with the concave side facing toward the front of the aircraft, so that the ridge is dug as the aircraft advances, and the trough groove is filled with the member. is there.

さらに、機体左右他側の引抜フレーム15の引抜搬送始端側に支持ステー210を設け、該支持ステー210に土寄せ昇降シリンダ211の固定側を設けると共に、該土寄せ昇降シリンダ211の移動側に連結シャフト212の左右一側端部を装着する。該連結シャフト212と土寄せ昇降シリンダ211の移動側の連結には、トルクシャーボルト等、所定値以上の過負荷がかかると自壊する固定部材213を用いる。   Further, a support stay 210 is provided on the drawing conveyance start end side of the drawing frame 15 on the left and right other sides of the machine body. The support stay 210 is provided with a fixed side of the earth lifting elevating cylinder 211, and a connecting shaft 212 is provided on the moving side of the earth raising elevating cylinder 211. Attach the left and right ends of the. A fixed member 213 that self-destructs when an overload of a predetermined value or more is applied, such as a torque shear bolt, is used for connecting the connecting shaft 212 and the earthing lift cylinder 211 on the moving side.

そして、前記連結シャフト212の左右他側端部は、前記回動フレーム204の機体左右一側で且つ後側の土寄せディスク207rよりも機体後側位置に取り付け、前記土寄せ昇降シリンダ211の伸縮動作に連動して上下動する構成とすることにより、土寄せ装置214が構成される。   The left and right other ends of the connecting shaft 212 are attached to the left and right sides of the body of the rotating frame 204 and to the rear side of the body of the rear side of the body-carrying disk 207r. The earth moving device 214 is configured by moving up and down in conjunction with each other.

なお、前記保持プレート205を取り外すと共に、連結シャフト212を土寄せ昇降シリンダ211から取り外すと、回動フレーム204をスライドさせて取り外すことができる構成となるので、土寄せ装置214の着脱に要する時間を短縮することができ、作業能率が向上する。   Note that when the holding plate 205 is removed and the connecting shaft 212 is removed from the dirt raising / lowering cylinder 211, the rotation frame 204 can be slid and removed, so that the time required for attaching / detaching the earthing device 214 is shortened. Can improve work efficiency.

さらに、前記土寄せ昇降シリンダ211は、引抜搬送装置24の昇降油圧シリンダ23とは独立して昇降操作することもできるものとすべく、電動シリンダとする。そして、前記土寄せ昇降シリンダ211を伸縮させて土寄せ装置214の作業高さを上下調節する土寄せ操作スイッチ215を前記操縦パネル12に設けることにより、土寄せ部Hが形成される。   Further, the earth lifting elevating cylinder 211 is an electric cylinder so that it can be operated up and down independently of the elevating hydraulic cylinder 23 of the pulling and conveying device 24. Then, by providing the earthing operation switch 215 for adjusting the working height of the earthing device 214 up and down by expanding and contracting the earthing lifting and lowering cylinder 211, the earthing part H is formed.

上記構成としたことにより、人参の引き抜き収穫作業を行いながら、前後の土寄せディスク207a,207bで畝溝を、畝上の土を寄せて埋めることができるので、左側のクローラ6Lが畝上を走行すると共に右側のクローラ6Rが畝溝を走行する際、機体が右方向に傾斜することが防止され、引抜搬送装置24が確実に人参の茎葉部を挟持して引き抜くため、抜き残した人参を手作業で回収する作業が不要となる。   By adopting the above configuration, the crawler groove can be filled with the front and rear soiling discs 207a and 207b while the carrot pulling and harvesting operation is performed, so the left crawler 6L runs on the foot. In addition, when the right crawler 6R travels in the ridge groove, the machine body is prevented from tilting to the right, and the pulling / conveying device 24 securely pulls out the ginseng foliage and pulls out the remaining carrot. Work to collect by work is not necessary.

特に、海岸に近い圃場では、塩害による人参の生育不良や枯れを避けるべく、畝の高さを標準的な圃場の倍近い高さ(約30cm前後)とする必要がある。この畝上を左側のクローラ6Lが走行し、畝溝を右クローラ6Rが走行するとき、機体は右側に大幅に傾斜してしまうことになるので、作業者が不快感を覚えるだけでなく、引抜搬送装置24の引抜搬送始端部も傾斜方向にずれてしまい、人参の茎葉部を挟持できず、人参の抜き残しを生じさせることになる。   In particular, in the field close to the coast, it is necessary to make the height of the ridge nearly twice as high as that of a standard field (about 30 cm) in order to avoid poor growth and withering of carrots due to salt damage. When the left crawler 6L travels on this saddle and the right crawler 6R travels in the trough, the aircraft will tilt significantly to the right, so that the operator will not only feel uncomfortable, but also pull out The pulling and conveying start end portion of the conveying device 24 is also shifted in the inclination direction, so that the ginseng stems and leaves cannot be sandwiched, resulting in uncarried ginseng.

また、引き抜かれた人参も機体の傾斜と同じ方向に傾くので、後述する茎葉切断装置61が茎葉部を切り残すことや、茎葉部だけでなく根部まで切断してしまい、作業者が茎葉部を手作業で除去しなければならず、作業者の労力が増大すると共に、人参の商品価値が低下してしまう。   In addition, since the pulled out carrot is also tilted in the same direction as the inclination of the aircraft, the foliage cutting device 61 described later cuts off the foliage part or cuts not only the foliage part but also the root part, and the operator removes the foliage part. It must be removed manually, increasing the labor of the operator and reducing the product value of the carrot.

この問題を解決すべく、本件の土寄せ装置214を設けると、機体が前進する際、畝溝に畝上の土を寄せていくので、右側のクローラ6Rが畝溝上を通過しても、機体の傾斜が生じない、もしくは、傾斜しても傾斜量が小幅となるので、引抜搬送装置24の引抜作業には支障が生じず、引抜収穫作業の能率の向上や、人参の抜き残しの発生が防止される。   In order to solve this problem, when the earthing device 214 of the present case is provided, when the aircraft advances, the soil on the ridge is moved to the ridge, so even if the crawler 6R on the right side passes over the ridge, No tilting occurs or the tilting amount is small even if tilted, so there is no hindrance to the pulling operation of the pulling and conveying device 24, and the efficiency of the pulling and harvesting work is improved and the occurrence of uncarried carrots is prevented. Is done.

なお、走行部Aで述べた、左右のクローラ6L,6Rの何れか一方を上下動可能に構成していれば、作業者が機体の傾斜を判断すると、手作業で機体を水平姿勢に操作することができる、あるいは傾斜センサの検知によって自動的にクローラ6L,6Rのどちらかを上下動させ、機体を自動的に水平姿勢とすることができるので、いっそう引抜搬送装置24が人参を引き残しにくくなる。   If either one of the left and right crawlers 6L and 6R described in the traveling section A is configured to be movable up and down, the operator manually operates the aircraft in a horizontal posture when the operator determines the inclination of the aircraft. Or the crawlers 6L and 6R can be automatically moved up and down by the detection of the tilt sensor to automatically bring the machine body into a horizontal posture, so that the pulling and conveying device 24 is less likely to leave carrots. Become.

また、前後の土寄せディスク207f,207rが、相互にオーバーラップする配置としたことにより、前側の土寄せディスク207fと後側の土寄せディスク207rの隙間から移動させている土が洩れ出すことを防止できるので、畝溝に移動させる土の量が不足し、畝溝上を通過する際に機体が大幅に傾斜することが防止されるため、引抜搬送装置24が人参を引き抜き残すことが防止される。   In addition, since the front and rear earthing disks 207f and 207r are arranged so as to overlap each other, it is possible to prevent the soil moving from the gap between the front earthing disk 207f and the rear earthing disk 207r from leaking. Since the amount of soil to be moved to the trough is insufficient and the machine body is prevented from being significantly inclined when passing over the trough, it is prevented that the pulling and conveying device 24 leaves the carrot.

そして、前後の土寄せディスク207f,207rを設けた回動フレーム204を土寄せ昇降シリンダ211で上下回動させる構成としたことにより、引抜搬送装置24の茎葉部の挟持高さを変更することなく前後の土寄せディスク207f,207rの作業高さを調節することができるので、人参の抜き残しが防止されると共に、畝溝を確実に埋め立てて、機体の左右方向の傾斜が防止される。   Then, the rotating frame 204 provided with the front and rear earthing discs 207f and 207r is configured to rotate up and down by the earth raising and lowering cylinder 211, so that the holding height of the foliage portion of the pulling and conveying device 24 can be changed without changing the front and rear. Since the working heights of the earthing discs 207f and 207r can be adjusted, it is possible to prevent the carrots from being left untouched and to reliably fill the ridges and prevent the aircraft from tilting in the horizontal direction.

さらに、土寄せ昇降シリンダ211の固定側を機体左右他側の引抜フレーム15に取り付け、移動側を連結シャフト212を介して回動アーム204に取り付けたことにより、引抜搬送装置24を昇降させると土寄せ装置214が連動して昇降するので、旋回時や非作業時等、引抜搬送装置24を上昇させる際に土寄せ装置214を個別に操作しなくても圃場面から離間させることができ、作業能率が向上する。   Further, when the pulling conveying device 24 is moved up and down by attaching the fixed side of the earthing lift cylinder 211 to the drawing frame 15 on the other left and right sides of the machine body and attaching the moving side to the rotating arm 204 via the connecting shaft 212, the earthing device Since 214 is moved up and down in conjunction with each other, it is possible to move away from the field scene without operating the mulching device 214 individually when raising the pulling and conveying device 24 such as when turning or when not working, improving work efficiency. To do.

また、前後の土寄せディスク207f,207rよりも機体後側で土寄せ昇降シリンダ211と連結シャフト212を連結したことにより、運ばれてくる土が土寄せ昇降シリンダ211の移動側に接触することを防止できるので、土寄せ昇降シリンダ211に土が付着して動作不良を起こすことや、破損することが防止される。   In addition, since the earthing lift cylinder 211 and the connecting shaft 212 are connected to the rear side of the machine with respect to the front and rear earthing disks 207f and 207r, it is possible to prevent the soil being carried from coming into contact with the moving side of the earthing elevator cylinder 211. Thus, it is possible to prevent soil from adhering to the dirt raising / lowering cylinder 211 to cause malfunction or damage.

そして、連結シャフト212を、所定値以上の過負荷がかかると自壊する固定部材213を用いて土寄せ昇降シリンダ211と連結したことにより、土中の石に接触したときなど、土寄せ装置214に過負荷がかかることがあると固定部材213が自壊して連結状態を解除するので、土寄せ昇降シリンダ211及び引抜搬送装置24には過負荷が伝わらず、破損が防止される。   Then, by connecting the connecting shaft 212 to the earth raising / lowering cylinder 211 using a fixing member 213 that self-destructs when an overload of a predetermined value or more is applied, the earthing device 214 is overloaded when it comes into contact with stones in the soil. If this happens, the fixing member 213 breaks down and the connected state is released, so that no overload is transmitted to the soil raising / lowering cylinder 211 and the drawing / conveying device 24, and damage is prevented.

加えて、連結が解除されることにより、土寄せ装置214側は回動アーム204が下方から加わる力に従って上方に回動することができるので、回動アーム204や土寄せメインフレーム201の破損も防止される。   In addition, since the connection is released, the mulching device 214 side can be rotated upward according to the force applied by the rotating arm 204 from below, so that the rotating arm 204 and the damming main frame 201 can be prevented from being damaged. The

このとき、破損の可能性があるのは直接石等の抵抗体に接触する前後の土寄せディスク207f,207rであるが、土寄せメインフレーム201や回動フレーム204と比べると着脱が容易であると共に、土寄せ昇降シリンダ211や引抜搬送装置24と比べると安価な部品であるので、破損が生じた際、交換作業に要する労力や部品のコストが軽減される。   At this time, there is a possibility of breakage of the earthing disks 207f and 207r before and after directly contacting a resistor such as a stone, but it is easier to attach and detach than the earthing main frame 201 and the rotating frame 204, Since it is a cheaper part compared to the earth lifting / lowering cylinder 211 and the pulling / conveying device 24, when a breakage occurs, the labor required for the replacement work and the cost of the part are reduced.

なお、図6、図7で示すとおり、土寄せメインフレーム201の前方に平面視でL字形状の前部キャリアフレーム216の長辺部を前後方向に向けて設け、該前部キャリアフレーム216の短辺部を左右方向に向けて操縦部Bの前方に位置させる。そして、該前部キャリアフレーム216の短辺部に回動支持プレート217,217を所定距離を開けて左右一対設け、該左右の回動支持プレート217,217に、コンテナ等の収容容器93を積載するフロントキャリア218を上下方向に回動自在に取り付ける構成としてもよい。   As shown in FIGS. 6 and 7, the long side portion of the L-shaped front carrier frame 216 in the plan view is provided in front of the lining main frame 201 in the front-rear direction, and the front carrier frame 216 has a short side. The side part is positioned in front of the control part B with the left and right direction. A pair of left and right rotation support plates 217 and 217 are provided on the short side portion of the front carrier frame 216 at a predetermined distance, and a container 93 such as a container is loaded on the left and right rotation support plates 217 and 217. It is good also as a structure which attaches the front carrier 218 to be rotated up and down freely.

上記構成としたことにより、フロントキャリア218に収容容器93を積載することができるので、収容容器93の積み下ろし作業や積み込み作業の頻度が減少し、作業能率が向上する。   With the above configuration, the storage container 93 can be loaded on the front carrier 218, so that the frequency of loading and unloading the storage container 93 and the loading operation are reduced, and the work efficiency is improved.

また、人参を積載して重量の増加した収容容器93を、機体左右他側に配置された操縦部Bの前部に位置するフロントキャリア218に積載すると、比較的重量があり、且つ人参の引抜荷重を受けやすい引抜搬送装置24のカウンターウェイトとなるので、機体の左右バランス調節が行え、走行性や人参の引抜精度の向上が図られる。   Further, when the container 93 loaded with carrots and increased in weight is loaded on the front carrier 218 located at the front part of the control part B arranged on the left and right other sides of the aircraft, it is relatively heavy and the carrot is pulled out. Since it becomes the counterweight of the pulling / conveying device 24 that is easily subjected to a load, the left / right balance of the machine body can be adjusted, and the running performance and the carrot pulling accuracy can be improved.

茎葉切断部Dについて説明する。
図1〜図3及び図11〜図13で示すように、前記伝動ケース22に駆動力を伝道する左右の伝動軸36,36を取り付け、該左右の伝動軸36,36の上部に左右伝動ケース37,37を取り付けると共に、該左右の伝動ケース37,37内に複数のギアを噛み合わせて構成する左右の第1ギアユニット38,38を機体前側に向かって取り付ける。また、前記伝動ケース22内部の左右の伝動軸36,36に左右の第2ギアユニット39,39を機体後側に向かって取り付け、該左右の第2ギアユニット39,39の後端部に左右の第1出力軸40,40を機体上方に向けて軸着する。
The foliage cutting part D is demonstrated.
As shown in FIGS. 1 to 3 and FIGS. 11 to 13, left and right transmission shafts 36 and 36 for transmitting driving force are attached to the transmission case 22, and left and right transmission cases are mounted on the left and right transmission shafts 36 and 36. 37, 37 are attached, and left and right first gear units 38, 38 configured by engaging a plurality of gears in the left and right transmission cases 37, 37 are attached toward the front side of the body.

Further, left and right alignment chains 48, 48 are wound endlessly around the alignment tension sprockets 47, 47, the alignment drive sprockets 42, 42, and the alignment driven sprockets 45, 45.

なお、前記位置揃え駆動スプロケット42,42は、位置揃え従動スプロケット45,45及び位置揃えテンションスプロケット47,47よりも小径のものを用いてもよい。
そして、前記伝動ケース37,37に左右の受け板49,49を前後方向に位置調節可能に取り付け、該受け板49,49と位置揃えフレーム43,43との間に、前記位置揃え従動スプロケット45,45を張圧して位置揃えチェーン48,48に生じる弛みを吸収させる左右の張圧バネ50,50を取り付ける。該張圧バネ50,50は、受け板49,49を前後に移動させることにより、位置揃え従動スプロケット47,47にかかる張圧力を変更することができ、人参の種類や生育状態、茎葉部の平均的な太さに応じて変更することで、様々な作業条件に対応することができる。
The alignment drive sprockets 42, 42 may have a smaller diameter than the alignment driven sprockets 45, 45 and the alignment tension sprockets 47, 47.
Then, left and right receiving plates 49, 49 are attached to the transmission cases 37, 37 so that their positions can be adjusted in the front-rear direction, and the alignment driven sprocket 45 is interposed between the receiving plates 49, 49 and the alignment frames 43, 43. , 45 are attached to the right and left tension springs 50, 50 to absorb slack generated in the alignment chains 48, 48. The tension pressure springs 50, 50 can change the tension pressure applied to the alignment driven sprockets 47, 47 by moving the receiving plates 49, 49 back and forth. By changing according to the average thickness, it is possible to cope with various work conditions.

また、前記左右の位置揃えフレーム43,43に機体左右方向の孔部44,44を形成、該孔部44,44に位置揃え従動スプロケット45,45の回転軸46,46を貫通させて設けたことにより、位置揃え従動スプロケット45,45を左右方向に移動させて位置調節することができるので、非作業時及び茎葉部が通過中でない、あるいは径の小さい茎葉部が通過する際は、位置揃え従動スプロケット47,47は張圧バネ50,50に押圧されて前側で且つ機体内側方向に向かって押圧され、大径の茎葉部が通過する際には位置揃え従動スプロケット47,47は機体外側方向に向かって押圧される構成となり、大径の茎葉部が噛み込まれることを防止でき、噛み込まれた茎葉部を取り除く必要が無く作業能率が向上する。   The left and right alignment frames 43, 43 are formed with holes 44, 44 in the left-right direction of the fuselage, and the rotation shafts 46, 46 of the alignment driven sprockets 45, 45 are provided through the holes 44, 44. As a result, it is possible to adjust the position by moving the aligned sprockets 45, 45 in the left-right direction. Therefore, when not working and when the foliage is not passing or when the foliage with a small diameter passes, the alignment is performed. The driven sprockets 47, 47 are pressed by the tension springs 50, 50 to the front side and toward the inner side of the machine body, and when the large diameter foliage passes, the aligned sprockets 47, 47 are moved to the outer side of the machine body. Therefore, it is possible to prevent the large-diameter foliage portion from being bitten, and it is not necessary to remove the bitten foliage portion, thereby improving work efficiency.

加えて、位置揃え装置54,54の搬送始端側から搬送終端側までの左右間隔が、大径の茎葉部が通過して負荷がかかったときのみ略直線状となるので、それ以外の場合には位置揃え装置の左右間隔を搬送始端側から搬送終端側に向かって広がる構成となり、位置揃え装置54,54の左右間隔を通過する人参が左右方向にふらつくことを防止でき、人参の茎葉部の切断位置揃えが適正に行なわれる。   In addition, the left-right distance from the conveyance start end side to the conveyance end side of the alignment devices 54, 54 becomes substantially linear only when a large diameter foliage part passes through and is loaded, so in other cases Has a configuration in which the left and right intervals of the alignment device are widened from the conveyance start end side toward the conveyance end side, so that ginseng passing through the left and right intervals of the alignment devices 54 and 54 can be prevented from fluctuating in the left and right direction. Cutting position alignment is performed properly.

さらに、大径の茎葉部が位置揃え装置54,54の左右間を通過できず、人参の茎葉部の切断位置が上がり過ぎ、根部に茎葉部が残ることを防止でき、後処理でこの茎葉部を取り除く作業が不要となり、作業能率が向上すると共に、人参が持ち上げられ過ぎ、根部を後述する茎葉切断装置61に切断されてしまうことを防止できるので、人参が傷付くことが無く、商品価値が向上する。   Further, the large diameter foliage part cannot pass between the right and left of the alignment devices 54, 54, the cutting position of the carrot foliage part is raised too much, and the foliage part can be prevented from remaining in the root part. The work efficiency is improved, the work efficiency is improved, the ginseng is lifted too much, and the root part can be prevented from being cut by the foliage cutting device 61, which will be described later. improves.

そして、前記位置揃えチェーン48,48を構成する複数のリンクピン48a…に、位置揃えチェーン48,48の上面と下面と茎葉部との接触面を覆う、断面形状コの字型のガイドカバー51…をそれぞれ取り付け、位置揃えガイド体52を構成する。   A plurality of link pins 48a... Constituting the alignment chains 48, 48 cover a contact surface between the upper surface, the lower surface, and the foliage of the alignment chains 48, 48. Are attached to form the alignment guide body 52.

なお、図14で示すように、該ガイドカバー51…は、正面または背面視においてコの字形に形成し、リンクピン48aに2つ毎に1個取り付けることにより、ガイドカバー51同士は干渉し合うことが無く位置揃えチェーン48,48の移動に追従することができるので、位置揃え装置54,54の移動がスムーズになり、作業能率が向上する。   As shown in FIG. 14, the guide covers 51 are formed in a U-shape when viewed from the front or back, and the guide covers 51 interfere with each other by attaching one to the link pins 48a. Since the movement of the alignment chains 48, 48 can be followed without any movement, the movement of the alignment devices 54, 54 becomes smooth, and the work efficiency is improved.

そして、前記位置揃えチェーン48,48の巻回域内で且つ位置揃え従動スプロケット45,45と位置揃えテンションスプロケット47,47との間に、位置揃えチェーン48,48を巻回域内から茎葉部接触面に向かって押圧する左右のテンションプレート53L,53Rを機体左右方向に位置調節自在に取り付けることにより、左右の位置揃え装置54,54が引抜搬送装置24の搬送方向後側の下方位置に構成される。   Then, the alignment chains 48, 48 are placed in the winding area of the alignment chains 48, 48 and between the alignment driven sprockets 45, 45 and the alignment tension sprockets 47, 47 from the winding area to the foliage contact surface.

また、前記左右第1出力軸40,40に左右茎葉搬送駆動プーリ62,62を軸着し、前記左右第1ギアユニット38,38よりも機体前側で且つ位置揃え装置54,54の上方に左右茎葉搬送従動プーリ63,63を回転自在に取り付ける。そして、該左右茎葉搬送駆動プーリ62,62と左右茎葉搬送従動プーリ63,63とに左右排葉搬送ベルト64,64を無端状に巻回することによって、前記引抜搬送装置24から人参の茎葉部を引き継いで機体後方に排出する排葉搬送装置65が、前記左右の伝動ケース37,37の上部外周で且つ引抜搬送装置24の搬送終端部側の下方に構成される。   Further, left and right foliage conveyance drive pulleys 62 and 62 are attached to the left and right first output shafts 40 and 40, and the left and right first and second gear units 38 and 38 are positioned in front of the machine body and above the alignment devices 54 and 54. The foliage driven pulleys 63 and 63 are rotatably attached. Then, the left and right foliage conveying belts 64, 64 are wound around the left and right foliage conveying drive pulleys 62, 62 and the left and right foliage conveying driven pulleys 63, 63 to endlessly form the carrot foliage from the pulling and conveying device 24. Is disposed on the outer periphery of the upper part of the left and right transmission cases 37 and 37 on the lower end side of the transporting end of the pulling transporting device 24.

さらに、前記左右第1出力軸40,40の上端部に左右残葉搬送駆動プーリ66,66を軸着し、前記伝動ケース37,37の上方に左右残葉搬送従動プーリ67,67を回転自在に取り付けるとともに、該左右残葉搬送駆動プーリ66,66と左右残葉搬送従動プーリ67,67との前後間に複数の左右の残葉搬送テンションプーリ68,68…を取り付ける。そして、前記左右残葉搬送駆動プーリ66,66と左右残葉搬送従動プーリ67,67と左右残葉搬送テンションプーリ68,68…とに左右残葉搬送ベルト69,69を無端状に巻回することによって、茎葉の上部を挟持して機体後方に搬送する残葉搬送装置70が、前記排葉搬送装置65の上方に構成される。   Further, left and right remaining leaf conveyance drive pulleys 66 and 66 are pivotally attached to the upper ends of the left and right first output shafts 40 and 40, and the left and right remaining leaf conveyance driven pulleys 67 and 67 are rotatable above the transmission cases 37 and 37. A plurality of left and right remaining leaf conveyance tension pulleys 68, 68 are attached between the left and right remaining leaf conveyance driving pulleys 66, 66 and the left and right remaining leaf conveyance driven pulleys 67, 67. Then, left and right residual leaf conveyance belts 69, 69 are wound endlessly around the left and right residual leaf conveyance driving pulleys 66, 66, left and right residual leaf conveyance driven pulleys 67, 67, and left and right residual leaf conveyance tension pulleys 68, 68. Thus, the remaining leaf conveyance device 70 that sandwiches the upper part of the foliage and conveys it to the rear of the machine body is configured above the defoliation conveyance device 65.

上記排葉搬送装置65と残葉搬送装置70の終端部から茎葉切断装置61によって切断された茎葉を圃場に排出する排葉プレート71を機体左右一側から左右他側に向かう傾斜姿勢で設けて、茎葉切断部Dを構成する。このとき、該排葉プレート71は、シュータの役割を果たす。   A leaf leaf plate 71 for discharging stems and leaves cut by the leaf and leaf cutting device 61 from the terminal portions of the leaf leaf conveying device 65 and the remaining leaf leaf conveying device 70 to the field is provided in an inclined posture toward the left and right sides from the left and right sides of the machine body. The stem-leaf cutting part D is comprised. At this time, the leaflet plate 71 serves as a shooter.

また、図11で示すとおり、前記左右の位置揃え装置54,54及び排葉搬送装置65の搬送始端側の上方で、且つ前記引抜搬送装置24を構成する左右の挟持搬送ベルト18,18の巻回域内に、人参の茎葉部を挟持搬送しつつ根部が位置揃え装置54,54に接触するように引き上げる搬送補助ローラ128…を前後方向に所定間隔毎に複数個、回転自在に配置する。該搬送補助ローラ128は、搬送補助回転軸128cの下部に人参の茎葉部を挟持する挟持回転体128aを軸着し、搬送補助回転軸128cの上部に人参之茎葉部を扱いて引き上げる扱き回転体128bを軸着して構成する。このとき、扱き回転体128bは挟持回転体128aよりも小径に構成する。   Further, as shown in FIG. 11, the left and right nipping and conveying belts 18 and 18 constituting the pulling and conveying device 24 above the conveying start end side of the left and right alignment devices 54 and 54 and the leaflet conveying device 65 are wound. Within the circulation zone, a plurality of conveyance auxiliary rollers 128 are arranged to rotate freely at predetermined intervals in the front-rear direction while nipping and conveying the carrot foliage so that the root portion contacts the alignment devices 54, 54. The conveyance auxiliary roller 128 has a holding rotary body 128a for pinching the ginseng stalks and leaves under the conveyance auxiliary rotation shaft 128c, and a handling rotation body for handling and lifting the ginseng stalks and leaves above the conveyance auxiliary rotation shaft 128c. 128b is pivotally configured. At this time, the handling rotary body 128b is configured to have a smaller diameter than the sandwiching rotary body 128a.

なお、搬送補助ローラ128は、上側の径が下側の径よりも小径となる、「凸」形状、あるいは「呂」形状の異型ローラとしてもよい。
上記構成により、左右の位置揃え駆動スプロケット42,42が、茎葉部が通過する位置揃え装置54,54の左右間隔部から離間する位置に配置されることにより、位置揃え駆動スプロケット42,42や第2出力軸41,41に茎葉部が絡み付いて位置揃え装置54,54を停止させてしまうことを防止できるので、収穫作業が中断されず、作業能率が向上する。
The conveyance auxiliary roller 128 may be a “convex” -shaped or “rho” -shaped atypical roller in which the upper diameter is smaller than the lower diameter.
With the above-described configuration, the left and right alignment drive sprockets 42 and 42 are arranged at positions spaced from the left and right spacing portions of the alignment devices 54 and 54 through which the foliage passes. Since it is possible to prevent the stems and leaves from being entangled with the two output shafts 41 and 41 to stop the alignment devices 54 and 54, the harvesting operation is not interrupted and the work efficiency is improved.

また、位置揃え駆動スプロケット42,42を位置揃え従動スプロケット45,45及び位置揃えテンションスプロケット47,47よりも小径としたことにより、位置揃え駆動スプロケット42,42がいっそう位置揃え装置54,54の左右間隔部から離間するので、位置揃え駆動スプロケット42,42や第2出力軸41,41に茎葉部が絡み付くことをいっそう防止でき、作業能率がさらに向上する。   Further, since the alignment drive sprockets 42 and 42 have a smaller diameter than the alignment driven sprockets 45 and 45 and the alignment tension sprockets 47 and 47, the alignment drive sprockets 42 and 42 are further left and right of the alignment devices 54 and 54. Since it leaves | separates from a space | interval part, it can further prevent that a foliage part gets entangled with the alignment drive sprockets 42 and 42 and the 2nd output shafts 41 and 41, and working efficiency further improves.

そして、位置揃え従動スプロケット45,45を張圧する左右の張圧バネ50,50を設けたことにより、位置揃え装置54,54に茎葉部が接触する際に左右の位置揃えチェーン48,48に生じる弛みを吸収させることができ、位置揃えチェーン48,48がすぐに張り状態に戻るため、径の異なる茎葉部が連続して通過するときでも位置揃え装置54,54が確実に人参の茎葉部を受けることができ、人参の茎葉部の切断位置が適正に揃えられて茎葉部が適正に切断され、後工程で茎葉部を除去する必要が無く、作業能率が向上する。   The left and right tension springs 50 and 50 for tensioning the alignment driven sprockets 45 and 45 are provided, so that the left and right alignment chains 48 and 48 are generated when the foliage comes into contact with the alignment devices 54 and 54. Since the slack can be absorbed and the alignment chains 48 and 48 immediately return to the tensioned state, the alignment devices 54 and 54 ensure that the ginseng foliage even when the foliage portions having different diameters pass continuously. The cutting position of the carrot foliage is properly aligned and the foliage is cut appropriately, and there is no need to remove the foliage in a later process, improving the work efficiency.

また、左右の受け板49,49を前後方向に移動させることで張圧バネ50,50の張力が調節されることにより、人参の生育状況や品種による茎葉部の径の差異、あるいは天候や土質等、作業場所の作業条件に合わせて張力を適正に変更できるので、人参の茎葉切断位置の位置揃えを適正に行い茎葉部を確実に切断することにより、後工程で人参に残る茎葉部を取り除く必要がなくなり、作業能率が向上する。   Further, the tension of the tension springs 50, 50 is adjusted by moving the left and right receiving plates 49, 49 in the front-rear direction, so that the growth status of the carrots, the difference in the diameter of the foliage depending on the variety, or the weather and soil quality The tension can be changed appropriately according to the working conditions at the work place, etc., so that the stems and leaves remaining in the carrots are removed in the subsequent process by properly aligning the carrot foliage cutting position and cutting the foliage parts reliably. This eliminates the need for work efficiency.

さらに、左右の位置揃えフレーム43,43に機体左右方向の孔部44,44を形成し、この孔部44,44に位置揃え従動スプロケット45,45を軸着した回転軸46,46を移動自在に設けたことにより、負荷がかからない状態では、張圧バネ50,50に張圧された位置揃え従動スプロケット45,45は茎葉部の搬送経路寄りに移動するので、小径の茎葉部が通過する際に位置揃え装置54,54が茎葉部を受けて人参の茎葉部の切断位置を適正に揃えることができ、後工程で人参に残る茎葉部を取り除く必要がなくなり、作業能率が向上する。   Further, the left and right alignment frames 43, 43 are formed with holes 44, 44 in the left-right direction of the machine body, and the rotation shafts 46, 46 having the alignment driven sprockets 45, 45 attached to the holes 44, 44 are movable. In the state where no load is applied, the alignment driven sprockets 45, 45 tensioned by the tension springs 50, 50 move toward the conveyance path of the foliage portion, so that the small diameter foliage portion passes through. In addition, the alignment devices 54 and 54 can receive the foliage portion to properly align the cutting position of the ginseng foliage portion, so that it is not necessary to remove the foliage portion remaining in the ginseng in the subsequent process, and the work efficiency is improved.

また、大径の茎葉部が通過する際、左右の位置揃え装置54,54に大きな負荷がかかると、位置揃え従動スプロケット45,45は孔部44,44に沿って茎葉部の移動経路から離間する方向に移動するので、位置揃え装置54,54の前側の左右間隔が広くなり、茎葉部が位置揃え装置54,54の間隔部に噛み込まれることを防止でき、機体を止めて噛み込まれた茎葉部を取り除く必要が無く、作業能率が向上する。   Further, when a large load is applied to the left and right alignment devices 54 and 54 when the large diameter foliage part passes, the alignment driven sprockets 45 and 45 are separated from the movement path of the foliage part along the holes 44 and 44. Therefore, the front left and right intervals of the alignment devices 54 and 54 are widened, so that the foliage portion can be prevented from being caught in the interval portions of the alignment devices 54 and 54, and the body is stopped and bitten. There is no need to remove the foliage and the work efficiency is improved.

なお、人参の茎葉部が須らく大径であることが収穫作業前にわかっている場合には、位置揃え従動スプロケット45,45を左右の位置揃え装置54,54の左右間から離間する方向に移動させ、位置揃え装置54,54の搬送方向上手側の左右間隔を広くしておくと、位置揃え装置54,54が茎葉部を噛み込むことを防止でき、噛み込んだ茎葉部を取り除く作業が必要なく、作業能率が向上する。   If it is known before harvesting that the carrot foliage has a large diameter, move the alignment driven sprockets 45, 45 away from the left and right of the left and right alignment devices 54, 54. If the left and right intervals on the upper side in the conveying direction of the alignment devices 54 and 54 are widened, the alignment devices 54 and 54 can be prevented from biting the foliage, and the work of removing the bited foliage is necessary. No work efficiency is improved.

そして、位置揃えチェーン48,48を構成する複数のリンクピン48a…毎にガイドカバー51…を取り付けて位置揃えガイド体52を構成したことにより、任意の箇所のガイドカバー51を自在に着脱できるので、一部のガイドカバー51が損傷しても、新しいガイドカバー51に取り替えるだけで適正な位置揃え性能が維持され、茎葉部が適正に切断されるので、作業能率が向上する。   Since the guide cover 51 is attached to each of the plurality of link pins 48a constituting the alignment chains 48, 48 to constitute the alignment guide body 52, the guide cover 51 at an arbitrary position can be freely attached and detached. Even if a part of the guide covers 51 is damaged, it is possible to maintain proper alignment performance simply by replacing the guide covers 51 with new guide covers 51, and the foliage portions are appropriately cut, so that the work efficiency is improved.

また、位置揃えガイド体52全体を取り替える必要がないので、コストダウンを図ることができる。
さらに、ガイドカバー51の着脱は、工具を必要とせず手作業で行なえるので、交換作業を容易に行なうことができる。
Moreover, since it is not necessary to replace the entire alignment guide body 52, the cost can be reduced.
Furthermore, since the guide cover 51 can be attached and detached manually without the need for a tool, the replacement work can be easily performed.

そして、ガイドカバー51が位置揃えチェーン48の上面と下面と茎葉部との接触面を覆う正面視コの字形状としたことにより、ガイドカバー51と位置揃えチェーン48との間に空間部が生じないので、ガイドカバー51と位置揃えチェーン48との間で茎葉部を挟み込んでしまい、人参が適正な切断位置に揃えられず茎葉部が切り残されることを防止でき、後工程で茎葉部を除去する作業が必要なく、作業能率が向上するとともに、人参の根部が切断されることを防止でき、人参の商品価値が向上する。   Since the guide cover 51 has a U-shape in front view covering the contact surfaces of the upper and lower surfaces of the alignment chain 48 and the foliage, a space portion is generated between the guide cover 51 and the alignment chain 48. As a result, the foliage is sandwiched between the guide cover 51 and the alignment chain 48, so that ginseng is not aligned at the proper cutting position and the foliage is left uncut, and the foliage is removed in a later process. The work efficiency is improved, the carrot root is prevented from being cut, and the product value of the carrot is improved.

そして、位置揃えチェーン48,48の巻回域内に左右のテンションプレート53L,53Rを設けたことにより、位置揃えチェーン48,48を巻回域内から押圧するため、大径の茎葉部が通過する際、テンションプレート53Lまたはテンションプレート53Rが押圧していない部分の位置揃えチェーン48,48は位置揃え駆動スプロケット42,42の方向へ退避できるので、茎葉部が位置揃え装置54,54の左右間に噛み込まれることが無く、機体を止めて噛み込まれた茎葉部を取り除く必要が無く、作業能率が向上する。   When the right and left tension plates 53L and 53R are provided in the winding region of the alignment chains 48 and 48, the alignment chains 48 and 48 are pressed from within the winding region. The portions of the alignment chains 48, 48 that are not pressed by the tension plate 53L or the tension plate 53R can be retracted in the direction of the alignment drive sprockets 42, 42, so that the foliage is engaged between the left and right of the alignment devices 54, 54. There is no need to remove the foliage that has been bitten by stopping the airframe, and the work efficiency is improved.

そして、茎葉切断装置61で人参から切断された排葉(切断された茎葉部)を圃場に排出する排葉プレート71が、既掘り側(人参を収穫し終えた側)に茎葉を排出するように下方傾斜姿勢に設けられていることによって、排出された茎葉が未掘り側(人参を収穫していない側)の人参の上に落下し、排葉が左右挟持搬送ベルト19,19や左右従動プーリ17,17等に絡み付いて収穫部Cを停止させて収穫作業を妨げることが防止できるので、作業能率が向上すると共に、人参の上に落下した排葉が収穫する人参の視認性を妨げることを防止できる。   And the leaf removal plate 71 which discharges the leaf leaves cut from the carrot by the stem-and-leaves cutting device 61 (the cut leaves and leaves) to the field seems to discharge the leaves and leaves to the already dug side (the side where the carrot has been harvested). Is provided in a downwardly inclined position, the discharged stems and leaves fall on the carrots on the undigged side (the side where the carrots are not harvested), and the drainage leaves the left and right nipping and conveying belts 19 and 19 and the left and right driven Since it is possible to prevent the harvesting section C from being stopped by being entangled with the pulleys 17, 17, etc., it is possible to prevent the harvesting operation from being disturbed. Can be prevented.

また、左右の挟持搬送ベルト18,18の巻回域内に複数の搬送補助ローラ128…を設け、この搬送補助ローラ128を構成する上側の扱き回転体128bを下側の挟持回転体128aよりも小径に構成したことにより、左右の茎葉部が補助搬送ローラ128,128の間を通過する際、左右の挟持搬送ベルト18,18の下部側は閉じて茎葉部を挟持し、上部側は開いて根部が位置揃え装置54,54に接触するまでの茎葉部の扱き上げを妨げない構造となるので、位置揃え装置54,54に人参が移動する際、引抜搬送装置24に挟持搬送された茎葉部が上方にも下方にも動けず、千切れてしまうことが防止されるため、搬送途中で人参が落下することが無く、収穫作業後に手作業で残葉を処理する必要が無く、作業者の労力が軽減される。   Further, a plurality of auxiliary conveyance rollers 128 are provided in the winding region of the left and right nipping and conveying belts 18, and the upper handling rotary body 128b constituting the auxiliary conveying roller 128 has a smaller diameter than the lower holding rotary body 128a. When the left and right foliage parts pass between the auxiliary conveyance rollers 128 and 128, the lower side of the left and right nipping conveyance belts 18 and 18 is closed and the foliage part is nipped, and the upper side is opened and the root part is opened. Therefore, when the carrots move to the alignment devices 54, 54, the foliage portions sandwiched and transported by the pulling / conveying device 24 are removed. Since it does not move upward or downward, it is prevented from being cut off, so that the carrot does not fall in the middle of transportation, and there is no need to manually process the remaining leaves after the harvesting work. Is reduced That.

加えて、人参が機外及び搬送経路外に落下し、作業者が落下した人参を拾い集める必要がなくなるため、作業者の労力が軽減される。
そして、従来のように、左右の搬送補助ローラ128,128の左右間隔を収穫する人参の品種や生育状態に合わせて調節する頻度が低下するため、作業者は左右の搬送補助ローラ128,128の左右間隔を調節するために作業を中断する必要が無く、作業能率が向上する。
In addition, since the carrot falls outside the machine and the conveyance path, it is not necessary for the worker to pick up the dropped carrot, so that the labor of the worker is reduced.
And since the frequency which adjusts according to the kind and growth state of the ginseng which harvests the right-and-left space | interval of the left and right conveyance auxiliary rollers 128 and 128 according to the conventional technique decreases, the operator can adjust the left and right conveyance auxiliary rollers 128 and 128. There is no need to interrupt the work to adjust the left-right distance, and work efficiency is improved.

本件構成では、茎葉部の径が大きくても左右の挟持搬送ベルト18,18は茎葉部が細い、あるいは標準的な径である場合と同じ挙動をするため、調節の頻度が低下する。例外として規格外に大きな人参(3L〜4L超級)の存在があるが、このような人参は加工用に回されるか、あるいは生産者が出荷前に選り分けるため、一般的に市場に流通するものではなく、また頻出するものでもないため、万一茎葉部が千切れて落下しても、作業能率や作業者の労力を損ねるものではない。   In this configuration, even if the diameter of the foliage is large, the left and right nipping and conveying belts 18 and 18 behave in the same manner as when the foliage is thin or has a standard diameter, and therefore the frequency of adjustment is reduced. An exception is the presence of large ginseng (3L to 4L class) outside the standard, but such ginseng is usually used for processing or distributed to the market because producers select them before shipping. Since it is neither a thing nor a thing which appears frequently, even if a foliage part breaks and falls, work efficiency and the labor of an operator are not impaired.

次に、排葉回収部Iについて説明する。
図1〜5及び図15〜図17で示すとおり、前記排葉搬送装置65と残葉搬送装置70の搬送終端部の下方で且つ機体フレーム1の後端部にコの字形状の接続フレーム130を取り付け、該接続フレーム130の後部に取付フレーム131を取り付ける。そして、該取付フレーム131の後部に機体左右一側を開放した平面視コの字型の枠状の排葉回収フレーム132を上下方向に回動自在に取り付け、該排葉回収フレーム132と取付フレーム131との間に排葉回収フレーム132を機体の振動等で揺動させる揺動スプリング133を伸縮自在に取り付ける。
Next, the leaf collection part I will be described.
As shown in FIGS. 1 to 5 and FIGS. 15 to 17, a U-shaped connecting frame 130 is provided below the conveying terminal portions of the defoliation conveying device 65 and the remaining leaf conveying device 70 and at the rear end of the body frame 1. And the attachment frame 131 is attached to the rear portion of the connection frame 130. Then, a U-shaped frame-shaped leaf collection frame 132 having a left-right side opened to the rear portion of the mounting frame 131 is attached so as to be rotatable in the vertical direction, and the leaf collection frame 132 and the attachment frame A swinging spring 133 for swinging the leaf collection frame 132 with the vibration of the airframe is attached between the head 131 and the head 131 so as to expand and contract.

前記排葉回収フレーム132の前端部には左右の取付長穴132a,132aを形成し、該左右の取付長穴132a,132aの後方に左右の回動支点穴132b,132bを形成する。また、前記取付フレーム131の後部で且つ排葉回収フレーム132の下部に排葉回収フレーム132の傾斜角度を変更する押しボルト134を回転自在に取り付け、該押しボルト134を回すと排葉回収フレーム132が回動支点を中心として上下方向に回動する構成とする。   Left and right attachment elongated holes 132a and 132a are formed at the front end of the leaf collection frame 132, and left and right pivot support holes 132b and 132b are formed behind the left and right attachment elongated holes 132a and 132a. A push bolt 134 for changing the inclination angle of the leaf collection frame 132 is rotatably attached to the rear portion of the mounting frame 131 and below the leaf collection frame 132. When the push bolt 134 is turned, the leaf collection frame 132 is rotated. Is configured to rotate in the vertical direction around the rotation fulcrum.

なお、押しボルト134は、機体後方に展開した排葉回収フレーム132を圃場面に対して水平状態とする位置を初期位置に設定し、押しボルト134が初期位置から上方に移動するように回すと排葉回収フレーム132の後端部が上昇する構成とすると、角度調節が行ないやすくなる。   When the push bolt 134 is rotated so that the position where the leaf collection frame 132 deployed rearward of the machine body is in a horizontal state with respect to the field scene is set to the initial position and the push bolt 134 is moved upward from the initial position. If the rear end portion of the leaf collection frame 132 is raised, the angle can be easily adjusted.

そして、前記後部フレーム120の上部に回動支軸141を設け、該回動支軸141に後述する延長フレーム135を引っ掛けて姿勢を固定する保持フック142を前後方向に回動自在に設ける。   A rotation support shaft 141 is provided on the upper portion of the rear frame 120, and a holding hook 142 that hooks an extension frame 135 (to be described later) on the rotation support shaft 141 to fix the posture is provided to be rotatable in the front-rear direction.

また、該排葉回収フレーム132の前後幅の内側で且つ機体左右一側(機体外側)に機体左右他側(機体内側)を開放した平面視コの字型の枠状の延長フレーム135を機体左右方向に回動自在に設け、該延長フレーム135を排葉回収フレーム132側に向かって張圧する前後の張圧スプリング136,136で延長フレーム135と排葉回収フレーム132とを連結する。   Further, an extension frame 135 having a U-shaped frame shape in a plan view in which the left and right other sides (the inner side of the body) are opened inside the front and rear width of the leaflet collection frame 132 and on the left and right sides (the outer side of the body) of the body. The extension frame 135 and the drainage leaf collection frame 132 are connected by front and rear tension springs 136 and 136 that are provided so as to be rotatable in the left-right direction and tension the extension frame 135 toward the leaflet collection frame 132 side.

前記延長フレーム135の機体前部側面には、排葉回収台140が機体フレーム1と略水平姿勢となり、排葉を回収する作業姿勢を保持する前側保持穴143fを形成する。また、延長フレーム135の機体後部側面には、排葉回収台140が後上がり傾斜姿勢となる収納姿勢を保持する後側保持穴143rを形成する。該前側保持穴143fまたは後側保持穴143rに前記保持フック142を引っ掛けることにより、作業姿勢または収納姿勢の何れかで排葉回収台140の姿勢が保持される。   On the front side surface of the extension frame 135, the leaf collection base 140 is in a substantially horizontal posture with the body frame 1, and a front holding hole 143 f that holds a working posture for collecting the leaf is formed. In addition, a rear holding hole 143r is formed on the rear side surface of the extension frame 135 so as to hold the storage posture in which the leaf collection base 140 is raised and inclined. By hooking the holding hook 142 in the front holding hole 143f or the rear holding hole 143r, the posture of the leaf collection table 140 is held in either the working posture or the storage posture.

該前後の張圧スプリング136,136の張力は、延長フレーム135を機体左右一側に展開した際、延長フレーム135の端部側が排葉回収フレーム132よりも上方に位置する箇所で係止する程度とする。より具体的にいえば、排葉回収フレーム132を0度とすると、機体左右一側方向に約120度〜150度展開した状態で延長フレーム135を係止し、それ以上は回動しない張力とする。   The tensions of the front and rear tension springs 136 and 136 are such that when the extension frame 135 is deployed to the left and right sides of the machine body, the end of the extension frame 135 is locked at a position positioned above the leaf collection frame 132. And More specifically, when the leaf collection frame 132 is set to 0 degree, the extension frame 135 is locked in a state where the extension frame 135 is expanded about 120 degrees to 150 degrees in the left-right direction of the airframe, and the tension that does not rotate any more. To do.

そして、前記排葉回収フレーム132に側面視逆U字型の摺動スライダ137…を排葉回収フレーム132上を摺動自在に複数配置し、該複数の摺動スライダ137…と排葉回収フレーム132と延長フレーム135とにメッシュ(網)状の排葉受け網138を紐体やバンド等で取り付ける。   Further, a plurality of slide sliders 137 having a reverse U-shape in side view are arranged on the leaf collection frame 132 so as to be slidable on the leaf collection frame 132, and the plurality of slide sliders 137 and the leaf collection frame are disposed. A mesh (net) -shaped leaflet receiving net 138 is attached to 132 and the extension frame 135 with a string or a band.

該排葉受け網138はナイロンや植物繊維等の軟質な紐材を網状に編み合わせたもので構成し、摺動スライダ137…と排葉回収フレーム132と延長フレーム135に取り付ける際は、中央部に行くほど圃場に向かって撓みが生じるように取り付ける。   The leaflet receiving net 138 is made of a braided soft string material such as nylon or vegetable fiber, and when attached to the sliding slider 137, the leaflet collecting frame 132, and the extension frame 135, the center portion Attach it so that it will bend toward the field as it goes to.

さらに、前記排葉回収フレーム132の機体左右一側の開放部側に前後方向に亘る補強フレーム139を取り付けることにより、排葉回収台140が構成されると共に、排葉回収部Iが構成される。   Further, by attaching a reinforcing frame 139 extending in the front-rear direction to the open side of the left and right sides of the body of the leaf collection frame 132, the leaf collection table 140 and the leaf collection unit I are constructed. .

上記構成により、排葉搬送装置65と残葉搬送装置70の搬送終端部から機体後方に排出される茎葉部を排葉受け網138で受けて回収することにより、圃場に人参の茎葉部を落とさずに人参の収穫作業を行うことができるので、人参の収穫後すぐに次の作物を栽培する際、圃場に放置した茎葉部に沸いた細菌やウィルスが原因で起こる連作障害が防止され、次の作物の生育や収穫が安定する。   With the above configuration, the stems and leaves discharged from the rear end of the body from the transfer terminal portions of the leaf removal transport device 65 and the remaining leaf transport device 70 are received and collected by the waste leaf receiving net 138, thereby dropping the carrot stems and leaves on the field. Therefore, when growing the next crop immediately after harvesting ginseng, it is possible to prevent continuous cropping troubles caused by bacteria and viruses boiling in the foliage left in the field. The growth and harvest of the crops are stable.

なお、人参を収穫し終えた後、茎葉部が圃場に養分として還元される期間を空けずに次の作物を栽培する場合であり、人参を収穫したあと期間を空ける場合、即ち茎葉部が圃場に養分として還元される期間を過ぎてから次の作物を栽培する場合には、茎葉部を圃場に排出し、耕耘機で土の中に混ぜ込む場合もある。上記の効果は、人参収穫作業後すぐに次の作物の栽培を開始する際、特に効力を発揮するものである。   In addition, after harvesting ginseng, it is a case where the next crop is cultivated without leaving a period in which the foliage is returned to the field as nutrients, and when a period is left after harvesting ginseng, that is, the foliage is in the field. When the next crop is cultivated after the period when it is reduced as nutrients, the foliage may be discharged to the field and mixed into the soil with a cultivator. The above effect is particularly effective when starting the cultivation of the next crop immediately after the carrot harvesting operation.

また、排葉受け網138で茎葉部を受けることにより、茎葉部に付着していた泥が圃場に落下するので、茎葉部を処分する前に太陽光や熱風で乾燥させる際に茎葉部を早く乾かすことができ、茎葉部の廃棄処理作業が効率よく行なえる。   In addition, the mud adhering to the foliage part falls to the field by receiving the foliage receiving net 138, so that when the foliage is dried with sunlight or hot air before disposal, It can be dried, and the waste disposal work can be performed efficiently.

そして、排葉回収フレーム132と取付フレーム131との間に揺動スプリング133を設けたことにより、排葉回収フレーム132は機体の走行や各構成部の駆動で生じる振動を受けて上下及び左右に揺動するため、茎葉部に付着した泥をいっそう落としやすくなり、茎葉部を早く乾かすことができるので、茎葉部の廃棄処理作業が効率よく行なえる。   Further, by providing a swinging spring 133 between the leaf collection frame 132 and the mounting frame 131, the leaf collection frame 132 is subjected to vibrations generated by the running of the machine body and the driving of each component so as to move vertically and horizontally. Since it swings, it becomes easier to remove mud adhering to the foliage part, and the foliage part can be dried quickly, so that the waste disposal work of the foliage part can be performed efficiently.

さらに、排葉受け網138で回収された茎葉部が揺動されることにより、茎葉部同士が圧縮されてまとまるので、茎葉部の収容量を増加させることができ、茎葉部を機外に降ろすために停止する頻度が減少し、作業能率が向上する。   Furthermore, since the foliage parts collected by the leaflet receiving net 138 are swung, the foliage parts are compressed and gathered together, so that the capacity of the foliage parts can be increased, and the foliage parts are lowered outside the machine. Therefore, the frequency of stopping is reduced, and work efficiency is improved.

また、排葉回収フレーム132を上下方向に回動させることにより、非作業時には排葉回収フレーム132を機体に近接させて折り畳むことができるので、機体の前後幅がコンパクトになり、軽トラック等の移送手段に積載する際に荷台から排葉回収フレーム132がはみ出すことが防止され、積み降ろしの度に排葉回収フレーム132を着脱する必要が無く、作業者の労力が軽減される。   In addition, by rotating the leaf collection frame 132 in the vertical direction, the leaf collection frame 132 can be folded close to the machine body when not in operation, so that the front and rear width of the machine body becomes compact and a light truck or the like can be folded. The leaf collection frame 132 is prevented from protruding from the loading platform when being loaded on the transfer means, and it is not necessary to attach or detach the leaf collection frame 132 every time it is unloaded, thereby reducing the labor of the operator.

そして、機体を荷台から降ろすとすぐに人参の収穫作業に取り掛かれると共に、機体を荷台に積載するとすぐに移動できるので、作業能率が向上する。
さらに、排葉回収フレーム132の傾斜角度を押しボルト134で調節可としたことにより、傾斜地にある圃場で作業をする場合でも排葉回収フレーム132を圃場に対して水平に配置することができるので、回収した茎葉部が排葉受け網138からこぼれ落ちて圃場に落下することを防止できる。
As soon as the aircraft is lowered from the loading platform, the carrot harvesting work is started, and when the aircraft is loaded on the loading platform, it can be moved immediately, so that the work efficiency is improved.
Further, since the inclination angle of the leaf collection frame 132 can be adjusted with the push bolt 134, the leaf collection frame 132 can be arranged horizontally with respect to the field even when working on the field on the slope. Thus, it is possible to prevent the collected foliage part from spilling from the leaflet receiving net 138 and falling to the field.

また、延長フレーム135を左右方向に回動自在に取り付けたことにより、茎葉部の収容量を増やすことができるので、茎葉部を機外に降ろすために停止する頻度が減少し、作業能率が向上する。   In addition, since the extension frame 135 can be pivoted in the left-right direction, the capacity of the foliage can be increased, so the frequency of stopping to drop the foliage to the outside of the machine is reduced, and the work efficiency is improved. To do.

そして、延長フレーム135を排葉回収フレーム132側に向かって張圧する前後の張圧スプリング136,136で延長フレーム135と排葉回収フレーム132とを連結したことにより、延長フレーム135は端部側が排葉回収フレーム132よりも上方に位置する状態で係止されるので、延長フレーム135の端部側の下方を人参の茎葉部が通過することができ、延長フレーム1335に引っ掛かって人参の茎葉部がちぎれることが防止されるので、引抜搬送装置24が人参の茎葉部を挟持できずに抜き残してしまうことが無く、収穫作業能率が向上すると共に、作業者が手作業で人参を引き抜く必要が無くなり、作業者の労力が軽減される。   The extension frame 135 and the leaf collection frame 132 are connected by the tension springs 136 and 136 before and after tensioning the extension frame 135 toward the leaf collection frame 132, so that the extension frame 135 is discharged at the end side. Since it is locked in a state of being positioned above the leaf collection frame 132, the ginseng foliage can pass below the end side of the extension frame 135, and the ginseng foliage is caught by the extension frame 1335. Since tearing is prevented, the pulling and conveying device 24 cannot pinch the ginseng stalks and leaves, so that the harvesting work efficiency is improved and the operator does not have to manually pull out the ginseng. , Labor of workers is reduced.

また、茎葉部の引っ掛かった人参が延長フレーム135に持ち上げられ、引抜搬送装置24が人参の根部を挟持して傷付けてしまうことを防止できるので、人参の商品価値が維持される。   In addition, the carrot with the foliage hooked on it can be prevented from being lifted by the extension frame 135 and the pulling and conveying device 24 pinching and caring the root of the carrot, thereby maintaining the commercial value of the carrot.

上記の効果は、茎葉部の繁茂しやすい春や夏の収穫作業時や、茎葉部の密度が高くなる品種を収穫作業時に特に効果を発揮することができる。
さらに、排葉回収フレーム132及び延長フレーム125と共に排葉受け網128を取り付ける複数の摺動スライダ137…を摺動自在に排葉回収フレーム132に設けたことにより、摺動スライダ137…を延長フレーム135側に摺動させると排葉受け網138と排葉回収フレーム132との間に茎葉部を圃場に落下させる空間部が形成されるので、排葉プレート71から落下してくる茎葉部をこの空間部に案内して圃場に直接落下させることで、茎葉部を圃場に直線状に並んで排出することができ、茎葉部が直線状に並んでいた箇所を畝とすると養分の豊富な場所で作物を栽培することができる。
The above-described effects can be exerted particularly during harvesting in spring and summer when the foliage part is prosperous, or when harvesting varieties with high foliage density.
Further, a plurality of sliding sliders 137 for attaching the leaf collection net 128 together with the leaf collection frame 132 and the extension frame 125 are slidably provided on the leaf collection frame 132, so that the slide slider 137 can be extended. When sliding toward the 135 side, a space for dropping the foliage part to the field is formed between the foliage receiving net 138 and the foliage collection frame 132, so that the foliage part falling from the foliage plate 71 is By directing it to the space and dropping it directly onto the field, the foliage can be discharged in a straight line on the field. Crop can be cultivated.

そして、排葉回収フレーム132の機体左右一側の開放部側に前後方向に亘る補強フレーム139を設けたことにより、排葉回収フレーム132の強度が向上すると共に、延長フレーム135を排葉回収フレーム132側に折り畳む際、排葉受け網138が必要以上に圃場に垂れ下がることを補強フレーム139が防止するので、排葉受け網138が圃場に接触することが防止され、排葉受け網138が破れて茎葉部が圃場に落下することがなくなる。   Further, by providing the reinforcing frame 139 extending in the front-rear direction on the open side of the left and right sides of the body of the leaf collection frame 132, the strength of the leaf collection frame 132 is improved and the extension frame 135 is attached to the leaf collection frame. When folded to the 132 side, the reinforcing frame 139 prevents the leaflet receiving net 138 from dropping more than necessary on the field, so that the leaflet receiving net 138 is prevented from contacting the field and the leaflet receiving net 138 is broken. The foliage will not fall into the field.

さらに、排葉回収台140を回動させて作業姿勢とし、延長フレーム135の機体前部側面に形成した前側保持穴143fに保持フック142を回動させて差し込むことにより、排葉回収台140を作業姿勢で保持することができるので、機体の振動等により排葉回収台140が上下動することが防止され、回収した茎葉部が圃場に落下することが防止される。   Further, the leaf collection table 140 is turned to a working posture, and the holding hook 142 is rotated and inserted into the front holding hole 143f formed on the front side surface of the extension frame 135, so that the leaf collection table 140 is Since it can be held in a working posture, the leaf collection table 140 is prevented from moving up and down due to vibrations of the machine body and the collected foliage is prevented from falling to the field.

また、排葉回収台140を回動させて収納姿勢とし、延長フレーム135の機体後部側面に形成した後側保持穴143fに保持フック142を回動させて差し込むことにより、排葉回収台140を収納姿勢で保持することができるので、機体の収納作業中や移送中に排葉回収台140が回動して作業姿勢になり、機体後方に突出することが防止されるため、排葉回収台140が周囲と接触して破損することが防止される。   Further, the leaf collection base 140 is rotated to the storage position, and the holding hook 142 is rotated and inserted into the rear holding hole 143f formed on the rear side surface of the extension frame 135, so that the leaf collection base 140 is Since it can be held in the storage posture, the leaf collection table 140 is prevented from rotating to the working posture during the storage operation or transfer of the machine body and protruding to the rear of the machine body. 140 is prevented from being damaged by contact with the surroundings.

次に、引継搬送部Eについて説明する。
図2及び図3で示すように、前記茎葉切断装置61の下方に前後の残葉処理フレーム72a,72bを設け、該前後の残葉処理フレーム72a,72bの左右両側の前後間に左右残葉処理ローラ73,73を回転自在に取り付ける。そして、該左右残葉処理ローラ73,73にゴムやウレタン等の弾性体で構成する残葉処理ベルト74を無端状に巻回し、該残葉処理ベルト74の上部に人参の根部に残った残葉を残葉処理ベルト74と共に挟み込んで回転して切除する残葉処理ローラ75を取り付けて、茎葉切断部Dから引き継いだ人参の残葉を処理しながら機体外側方向から左右内側方向に搬送する残葉処理コンベア76を構成する。
Next, the takeover conveyance unit E will be described.
As shown in FIGS. 2 and 3, front and rear remaining leaf processing frames 72a and 72b are provided below the foliage cutting device 61, and left and right residual leaves between the front and rear sides of the front and rear remaining leaf processing frames 72a and 72b. The processing rollers 73 and 73 are rotatably attached. Then, a remaining leaf treatment belt 74 made of an elastic material such as rubber or urethane is wound endlessly around the left and right remaining leaf treatment rollers 73, 73, and the residue remaining at the root of the carrot is left above the remaining leaf treatment belt 74. A remaining leaf processing roller 75 is attached to rotate and cut the leaf together with the remaining leaf processing belt 74, and the remaining leaves of the carrots taken over from the stem and leaf cutting part D are processed and transferred from the outer side of the machine body to the left and right inner side. A leaf processing conveyor 76 is configured.

また、該残葉処理コンベア76の始端側で且つ機体前側に茎葉切断装置61よりも機体前側に落下した作物を受ける格子状の受け台77を下り傾斜姿勢で設け、機体左右一側部で且つ該受け台77よりも機体内側に汲上搬送駆動ローラ78を設けると共に、左右他側部側に汲上搬送従動ローラ79を設ける。そして、前記残葉処理コンベア76よりも機体前側で且つ残葉処理コンベア76に隣接させて、汲上搬送駆動ローラ78と汲上搬送従動ローラ79とに汲上搬送ベルト80を無端状に巻回して、前記残葉処理コンベア76と受け台77とから人参を引き継いで機体左右他側に汲上搬送する汲上搬送コンベア81が構成される。   In addition, a lattice-shaped cradle 77 for receiving a crop that has fallen to the front side of the machine body from the foliage cutting device 61 is provided at the start side of the remaining leaf processing conveyor 76 and the front side of the machine body in a downwardly inclined posture, A pumping conveyance drive roller 78 is provided on the inner side of the machine body relative to the cradle 77, and a pumping conveyance driven roller 79 is provided on the left and right other side portions. Then, the pumping conveyance belt 80 is wound endlessly around the pumping conveyance driving roller 78 and the pumping conveyance driven roller 79 on the front side of the machine body and adjacent to the residual leaf processing conveyor 76 with respect to the residual leaf processing conveyor 76. A pumping conveyer 81 is formed which takes over the carrot from the remaining leaf processing conveyor 76 and the cradle 77 and pumps it to the left and right sides of the machine body.

前記残葉処理コンベア76と上り傾斜姿勢に設ける汲上搬送コンベア81とから、汲上搬送部Eが構成される。
上記構成により、残葉処理コンベア76を構成する残葉処理ローラ75が、茎葉切断装置61で切り残された人参の残葉を千切り取りながら汲上搬送コンベア81に人参を搬送するため、人参の商品価値が向上すると共に、収穫作業後に人手で残葉を切除する作業を省略することができ、作業能率が向上する。
A pumping conveyance unit E is constituted by the remaining leaf processing conveyor 76 and the pumping conveyance conveyor 81 provided in the upward inclined posture.
With the above configuration, the remaining leaf processing roller 75 constituting the remaining leaf processing conveyor 76 transports the carrots to the uplifting conveyor 81 while cutting off the remaining leaves of the carrots cut and left by the stem and leaf cutting device 61. The value is improved and the work of manually cutting the remaining leaves after the harvesting work can be omitted, and the work efficiency is improved.

また、残葉処理コンベア76を構成する残葉処理ベルト74をゴムやウレタン等の弾性体で構成したことによって、茎葉切断装置61で茎葉部を切除されて人参が落下しても残葉処理ベルト74が落下の衝撃を軽減するので、落下の衝撃で人参が傷付くことが防止され、人参の品質が向上する。   In addition, the remaining leaf processing belt 74 constituting the remaining leaf processing conveyor 76 is made of an elastic body such as rubber or urethane, so that the remaining leaf processing belt is removed even if carrots fall after the leaves are cut off by the foliage cutting device 61. Since 74 reduces the impact of the drop, the carrot is prevented from being damaged by the impact of the drop, and the quality of the carrot is improved.

そして、残葉処理コンベア76の始端側で且つ機体前側に格子状の受け台77を下り傾斜姿勢に設けたことによって、茎葉切断装置61よりも機体前側で茎葉部が千切れる等して落下した人参を、機外に落とすことなく受け止めることができると共に、受けた人参を汲上搬送コンベア81に向かって移動させることができるので、収穫作業後に機外に落ちた人参を拾い集める作業が省略されて作業者の労力が軽減されると共に、茎葉切断装置61よりも機体前側で落下した人参を搬送経路に戻すことができるので、作業能率が向上する。   Then, by providing a grid-like pedestal 77 on the starting end side of the remaining leaf processing conveyor 76 and on the front side of the machine body in a downward inclined posture, the foliage part fell off on the front side of the machine body from the foliage cutting device 61 and dropped. The carrot can be received without being dropped outside the machine, and the received carrot can be moved toward the pumping conveyor 81, so that the work of collecting the carrot that has fallen outside the machine after the harvesting work is omitted. The labor of the worker is reduced, and the carrot dropped on the front side of the machine body from the foliage cutting device 61 can be returned to the conveyance path, so that the work efficiency is improved.

次に、選別搬送部Fについて説明する。
図2及び図18で示すように、操縦部Bの後部に左右の選別搬送フレーム82,82を取り付け、該左右の選別搬送フレーム82,82の機体後側の左右間に選別搬送駆動スプロケット83,83を回転自在に設け、該選別搬送駆動スプロケット83,83よりも機体前側に、選別搬送従動スプロケット84,84を取り付けた自動テンション機構84a,84aを設ける。
Next, the sorting and conveying unit F will be described.
As shown in FIGS. 2 and 18, left and right sorting and conveying frames 82 and 82 are attached to the rear part of the control unit B, and the sorting and conveying drive sprocket 83 between the left and right rear sides of the left and right sorting and conveying frames 82 and 82 are provided. 83 is rotatably provided, and automatic tension mechanisms 84a and 84a having sorting and transporting driven sprockets 84 and 84 attached to the front side of the machine body relative to the sorting and transporting drive sprockets 83 and 83 are provided.

また、前記選別搬送駆動スプロケット83,83と選別搬送従動スプロケット84,84に亘って左右の伝動チェーン85,85を無端状に巻回し、該伝動チェーン85,85の左右間に複数の搬送バー86…を等間隔に配置する。さらに、前記選別搬送駆動スプロケット83,83の回転軸を回転させる選別搬送モータ87mを設けることにより、選別搬送コンベア87が構成される。   Further, left and right transmission chains 85 are wound endlessly across the sorting and conveying drive sprockets 83 and 83 and the sorting and conveying driven sprockets 84 and 84, and a plurality of conveying bars 86 are interposed between the left and right of the transmission chains 85 and 85. ... are arranged at equal intervals. Further, a sorting / conveying conveyor 87 is configured by providing a sorting / conveying motor 87m for rotating the rotating shafts of the sorting / conveying drive sprockets 83 and 83.

該選別搬送コンベア87は、搬送始端部よりも搬送終端部が僅かに上方に位置する後上り傾斜姿勢とし、搬送始端部を汲上搬送部Eの汲上搬送コンベア81の搬送終端部の下方に配置する。このとき、汲上搬送コンベア81の搬送終端部は、機体左右一側の自動テンション機構84aを跨いだ位置に配置する。   The sorting and conveying conveyor 87 has a rear upward inclined posture in which the conveyance end portion is positioned slightly above the conveyance start end portion, and the conveyance start end portion is disposed below the conveyance termination portion of the draw-up conveyance conveyor 81 of the draw-up conveyance portion E. . At this time, the conveyance termination part of the draw-up conveyance conveyor 81 is disposed at a position straddling the automatic tension mechanism 84a on the left and right sides of the machine body.

また、前記選別搬送駆動スプロケット83,83の回転軸にシュータ88を上下回動自在に取り付け、該シュータ88の機体左右外側にシュータ88を上下回動させる操作レバー89を取り付けることによって、選別搬送部Fが構成される。   Further, by attaching a shooter 88 to the rotation shaft of the sorting and conveying drive sprockets 83 and 83 so as to be rotatable up and down, and by attaching an operation lever 89 for rotating the shooter 88 up and down on the left and right outer sides of the shooter 88 F is configured.

上記構成のように、選別搬送従動スプロケット84,84を回転自在に取り付けた自動テンション機構84a,84aを設けたことにより、汲上搬送コンベア81から人参が落下してきたときなどに伝動チェーン85,85を撓ませることができるので、人参は落下の衝撃を吸収されて傷付くことを防止され、人参の商品価値が向上する。   As in the above configuration, by providing automatic tension mechanisms 84a and 84a to which sorting and conveying driven sprockets 84 and 84 are rotatably attached, the transmission chains 85 and 85 can be attached when the carrot falls from the pumping and conveying conveyor 81. Since it can be bent, the carrot is prevented from being damaged by absorbing the impact of the fall, and the commercial value of the carrot is improved.

また、選別搬送駆動スプロケット83,83を搬送終端部側に設けたことにより、自動テンション機構84a,84aがはたらいて伝動チェーン85,85が撓んでも、選別搬送コンベア87の搬送終端位置が変化しないので、選別搬送コンベア87と収容容器93との距離が変わることが防止され、人参の落下距離が一定に保たれ、落下の衝撃で傷付くことが防止される。   In addition, since the sorting and transporting drive sprockets 83 and 83 are provided on the transport end portion side, even if the automatic tension mechanisms 84a and 84a work and the transmission chains 85 and 85 are bent, the transport end position of the sorting and transporting conveyor 87 does not change. Therefore, the distance between the sorting and conveying conveyor 87 and the storage container 93 is prevented from changing, the carrot falling distance is kept constant, and it is prevented from being damaged by the impact of dropping.

そして、汲上搬送コンベア81の搬送終端部を、機体左右一側の自動テンション装置84aを跨いだ位置に配置したことにより、汲上搬送コンベア81から排出される人参が自動テンション装置84aや伝動チェーン85の上に落下しないので、人参が落下してくると自動テンション装置84aが作用して伝動チェーン85がしっかりと撓むため、落下の衝撃が吸収されて人参が傷付くことが防止される。   And by arranging the conveyance end portion of the draw-up conveyance conveyor 81 across the automatic tension device 84a on the left and right sides of the machine body, the carrots discharged from the draw-up conveyance conveyor 81 are separated from the automatic tension device 84a and the transmission chain 85. Since the carrot does not fall, the automatic tension device 84a acts when the carrot falls, so that the transmission chain 85 bends firmly, so that the impact of the fall is absorbed and the carrot is prevented from being damaged.

さらに、選別搬送コンベア87を、複数の搬送バー86…を左右の伝動チェーン85,85の左右間に等間隔に設けて構成したことにより、搬送バー86同士の間から人参に付着していた泥土や葉屑等の夾雑物を下方に落下させることができるので、夾雑物が選別対象の人参の形状や傷を隠すことが防止され、人参の選別精度が向上する。   Furthermore, since the sorting and conveying conveyor 87 is configured by providing a plurality of conveying bars 86 at equal intervals between the left and right of the left and right transmission chains 85, 85, the mud adhered to the carrot from between the conveying bars 86. As a result, it is possible to prevent foreign substances such as leaf dust and leaves from falling down, so that the foreign substances are prevented from concealing the shape and scratches of the carrots to be sorted, and the carrot sorting accuracy is improved.

また、シュータ88を上下回動自在に設けたことによって、シュータ88を下方回動させると人参を後述する収容部Gに設置するコンテナやフレコンバッグ等の収容容器93に緩やかに落とすことができるので、落下の衝撃で人参が傷付くことが防止され、人参の商品価値が向上する。   In addition, since the shooter 88 is provided so as to be pivotable up and down, when the shooter 88 is pivoted downward, the carrot can be gently dropped into a container 93 such as a container or a flexible container bag installed in the container G described later. In addition, the carrots are prevented from being damaged by the impact of falling, and the product value of the carrots is improved.

そして、シュータ88を上方に回動させると、選別搬送コンベア87の終端側を塞ぐストッパとなるため、人参が満杯になったコンテナを交換する際、選別搬送コンベア87を停止させなくても人参が終端部から落下することを防止することができるので、落下の衝撃で人参が傷付くことが防止されて人参の品質が向上すると共に、選別搬送コンベア87の動力の入切を頻繁に行う必要がなくなり、作業能率が向上する。   When the shooter 88 is rotated upward, it becomes a stopper that closes the terminal end side of the sorting and conveying conveyor 87. Therefore, when replacing a container full of carrots, the carrot can be moved without stopping the sorting and conveying conveyor 87. Since it is possible to prevent the carrot from falling from the end portion, it is necessary to prevent the carrot from being damaged by the impact of the drop, improve the quality of the carrot, and to frequently turn on and off the power of the sorting and conveying conveyor 87. The work efficiency is improved.

さらに、シュータ88を上方回動させてストッパとし、選別搬送コンベア87を停止させないことによって、人参は選別搬送コンベア87の終端側に溜まるので、従来のように汲上搬送コンベア81の搬送終端部から落下してきた人参が選別搬送コンベア87の搬送始端部に滞留している人参に接触して傷付くことが防止されるので、人参の商品価値が向上する。   Further, by rotating the shooter 88 as a stopper and not stopping the sorting / conveying conveyor 87, the carrot accumulates on the terminal end side of the sorting / conveying conveyor 87. Since the carrots that have been brought into contact with the carrots staying at the transport start end of the sorting and conveying conveyor 87 are prevented from being damaged, the product value of the carrots is improved.

また、シュータ88の機体左右外側にシュータ88を上下回動させる操作レバー89を取り付けたことによって、補助作業者は後述する補助作業座席117に座ったままシュータ88を上下回動させることができるので、補助作業者の労力が軽減される。   Further, by attaching an operation lever 89 for turning the shooter 88 up and down on the left and right outer sides of the body of the shooter 88, the auxiliary worker can turn the shooter 88 up and down while sitting on an auxiliary work seat 117 described later. The labor of auxiliary workers is reduced.

次に、収容部Gについて説明する。
図1、図2、図19、図20で示すように、前記左右選別搬送フレーム82,82の下部に前後回動自在に枠形状の載置支持フレーム90を設け、該載置支持フレーム90の空間部に前後方向の回転軸91…を複数並べて配置する。本実施例では三本の回転軸91a,91b,91cを、左右方向に間隔を空けて配置している。
Next, the accommodating part G is demonstrated.
As shown in FIGS. 1, 2, 19, and 20, a frame-shaped mounting support frame 90 is provided at the lower part of the left and right sorting and conveying frames 82 and 82 so as to be pivotable back and forth. A plurality of rotational shafts 91 in the front-rear direction are arranged side by side in the space. In the present embodiment, the three rotation shafts 91a, 91b, 91c are arranged at intervals in the left-right direction.

該回転軸91a,91b,91cのうち、機体左右一側、即ち選別搬送コンベア87の搬送終端部の下方に位置する載置支持フレーム90に回転軸91aを配置し、収容容器93の左右幅より短い間隔を空けて、機体左右他側、後述する収容容器載置台97側に回転軸91b,91cを回転軸91aよりも上方に配置する。   Among the rotating shafts 91 a, 91 b, 91 c, the rotating shaft 91 a is disposed on the mounting support frame 90 positioned on one side of the machine body, that is, below the transfer terminal end of the sorting transfer conveyor 87. Rotating shafts 91b and 91c are arranged above the rotating shaft 91a on the other side of the left and right sides of the machine body and on the container container mounting table 97 side to be described later with a short interval.

そして、前記回転軸91a,91b,91cにそれぞれ搬送ローラ92を、コンテナやフレコンバッグ、袋体等の収容容器93の搬送方向にのみ回転可能に装着する。回転方向を一方向に回転させるためには、搬送ローラ92にワンウェイクラッチ(図示省略)等の回転規制部材を用いるとよい。   And the conveyance roller 92 is each rotatably attached to the said rotating shaft 91a, 91b, 91c only in the conveyance direction of storage containers 93, such as a container, a flexible container bag, and a bag. In order to rotate the rotation direction in one direction, a rotation regulating member such as a one-way clutch (not shown) may be used for the conveyance roller 92.

なお、この搬送ローラ92は、図1、図2、図19で示すように、前後方向に複数(本実施例では分割搬送ローラ92x,92y,92z)に分割し、該分割搬送ローラ92x,92y,92z同士の間隔、及び載置支持フレーム90との間隔ができるだけ生じないように配置する。   1, 2, and 19, the conveying roller 92 is divided into a plurality of (in the present embodiment, divided conveying rollers 92 x, 92 y, 92 z) in the front-rear direction, and the divided conveying rollers 92 x, 92 y are divided. , 92z and the mounting support frame 90 are arranged in such a manner that the spacing between them and the mounting support frame 90 does not occur as much as possible.

さらに、機体左右一側に設ける前記回転軸91aの後部で且つ回転軸91aと載置支持フレーム90との間に皿バネ等のブレーキ体94を軸着し、回転軸91aの後端部に該ブレーキ体94の抵抗力を調節する調節ノブ95を調節自在に取り付ける。該ブレーキ体94は、調節ノブ95の調節操作に応じて加圧力を回転軸91aに加え、回転軸91aの回転を規制するものである。   Further, a brake body 94 such as a disc spring is attached to the rear portion of the rotary shaft 91a provided on the left and right sides of the machine body and between the rotary shaft 91a and the mounting support frame 90, and the brake shaft 94 is attached to the rear end portion of the rotary shaft 91a. An adjustment knob 95 for adjusting the resistance force of the brake body 94 is attached to be adjustable. The brake body 94 applies a pressure force to the rotating shaft 91a in accordance with the adjusting operation of the adjusting knob 95, thereby restricting the rotation of the rotating shaft 91a.

また、前記載置支持フレーム90に収容容器93の重量に応じて伸縮するダンパ96の一側端部を設け、該ダンパ96の他側端部を回動フレーム20に取り付ける。該ダンパ96は、収容容器93に投入された人参が少なく、重量が軽い場合は短く縮んで載置支持フレーム90を上方に回動させると共に、人参が投入されて重くなるにつれて長く伸び、載置支持フレーム90を下方に回動させる構成とする。   In addition, one end portion of the damper 96 that expands and contracts according to the weight of the storage container 93 is provided on the mounting support frame 90, and the other end portion of the damper 96 is attached to the rotating frame 20. The damper 96 has a small amount of carrot introduced into the storage container 93, and when the weight is light, the damper 96 is shortened to shorten and rotate the mounting support frame 90 upward. The support frame 90 is configured to rotate downward.

上記構成により、収容容器載置台97が構成される。
そして、該収容容器載置台97を構成する収容支持フレーム90の後部に空の収容容器93等を載置する予備収容容器載置台98を前後回動自在に、且つ収容容器載置台97が
圃場面に対して略水平姿勢であるときには後上り傾斜姿勢となるように取り付ける。該予備収容容器載置台98は、収容容器載置台97から収容容器93を取り除くと、積載している空の収容容器93を収容容器載置台97に滑り降ろす角度で配置する。このとき、人参を収容中の収容容器93の上部が、空の収容容器93のストッパの役割を果たしている。
With the above configuration, the storage container mounting table 97 is configured.
Then, a preliminary storage container mounting table 98 for mounting an empty storage container 93 or the like on the rear part of the storage support frame 90 that constitutes the storage container mounting table 97 can be rotated back and forth, and the storage container mounting table 97 can be rotated in the field. When it is in a substantially horizontal posture, it is attached so as to be in a back-up tilt posture. When the storage container 93 is removed from the storage container mounting table 97, the preliminary storage container mounting table 98 is disposed at an angle at which the empty storage container 93 loaded is slid down on the storage container mounting table 97. At this time, the upper part of the storage container 93 that stores the carrots serves as a stopper for the empty storage container 93.

また、前記選別搬送コンベア87の機体左右他側方に補助作業者が足を置くステップ99を設け、該ステップ99の下部に前後一対の取付アーム100,100を設け、該取付アーム100,100の機体左右他側端部に平面視H字形状の回動ステー101,101を取り付ける。さらに、該回動ステー101,101に中空の支持フレーム102,102を上下回動自在に設け、該支持フレーム102,102の上部に人参を収容した収容容器93を複数載置する貯留台103を、機体前後方向に長辺を向けて配置する。この貯留台103は、非作業時等には機体フレーム1側に回動させることができる構成とし、倉庫等に収容する際のスペースを少なくできる構成としている。   Further, a step 99 for placing an auxiliary worker's foot on the left and right sides of the sorting and conveying conveyor 87 is provided, and a pair of front and rear mounting arms 100 and 100 are provided below the step 99. Rotating stays 101, 101 having an H shape in plan view are attached to the left and right other ends of the machine body. Further, a hollow support frame 102, 102 is provided on the rotation stays 101, 101 so as to be rotatable up and down, and a storage table 103 for placing a plurality of storage containers 93 containing carrots on the support frames 102, 102 is provided. Arrange the long side in the longitudinal direction of the aircraft. The storage table 103 is configured to be able to be rotated to the side of the machine body frame 1 when not in operation or the like, and is configured to be able to reduce a space when housed in a warehouse or the like.

なお、ステップ99の機体左右他側端部は載置支持フレーム90の機体左右他側端部と略同じ位相とし、貯留台103の後端部は載置支持フレーム90の後端部と略同じ位相とする。   Note that the left and right other side ends of the machine body in step 99 have substantially the same phase as the left and right other side edges of the mounting support frame 90, and the rear end of the storage platform 103 is substantially the same as the rear end of the mounting support frame 90. Phase.

また、ステップ99の取付アーム100,100を回動ステー101,101を回動支点として、貯留台103を機体フレーム1側に回動させるとステップ99がこの貯留台103側に回動する構成としてもよい。   Further, when the mounting arm 100, 100 of the step 99 is rotated around the rotating stays 101, 101 and the storage base 103 is rotated toward the body frame 1, the step 99 is rotated toward the storage base 103. Also good.

上記構成によれば、貯留台103を上方回動させるとステップ99も上方回動して傾斜姿勢となることにより、選別搬送コンベア87や作業者の靴から落ちた泥土や葉屑等の夾雑物を下方に落とすことができるので、夾雑物の除去作業が容易となり、メンテナンス性が向上する。   According to the above configuration, when the storage table 103 is rotated upward, the step 99 is also rotated upward to be in an inclined posture, so that impurities such as mud and leaf waste dropped from the sorting and conveying conveyor 87 and the operator's shoes. Since it can be dropped downward, it is easy to remove foreign matters, and the maintainability is improved.

このとき、ステップ99の表面を凹凸のない平坦な構成としたり、泥土の付着しにくい素材で覆ったりすると、ステップ99を傾斜させた際にいっそう泥土が残りにくく、メンテナンス性がさらに向上する。   At this time, if the surface of step 99 has a flat structure without unevenness or is covered with a material that is difficult to adhere mud, the mud is less likely to remain when step 99 is tilted, and the maintainability is further improved.

そして、該貯留台103の前部に左右一対の駆動プーリ104,104を設け、貯留台103の後部に左右一対の従動プーリ105,105を設け、該駆動プーリ104,104と従動プーリ105,105の前後間に複数の搬送ローラ106,106…を回転自在に設ける。また、前記駆動プーリ104,104と従動プーリ105,105に2本の搬送ベルト107,107:107,107を左右間隔を空けて無端状に巻回する。該左右の搬送ベルト107,107:107,107の左右間には、前記搬送ローラ106,106…が搬送ベルト107,107:107,107と接触しない位置に設けられる。   A pair of left and right drive pulleys 104, 104 are provided at the front portion of the storage table 103, and a pair of left and right driven pulleys 105, 105 are provided at the rear portion of the storage table 103. The drive pulleys 104, 104 and the driven pulleys 105, 105 are provided. A plurality of transport rollers 106, 106... Further, two conveying belts 107, 107: 107, 107 are wound around the driving pulleys 104, 104 and the driven pulleys 105, 105 in an endless manner with a left-right interval. Between the left and right conveying belts 107, 107: 107, 107, the conveying rollers 106, 106... Are provided at positions where they do not contact the conveying belts 107, 107: 107, 107.

なお、搬送ローラ106,106…と搬送ベルト107,107:107,107の上面は、貯留台103の上端面よりも上方に位置すると、収容容器93が貯留台103の上面に接触して搬送されなくなることが防止されるので、作業能率が向上する。   When the upper surfaces of the conveying rollers 106, 106... And the conveying belts 107, 107: 107, 107 are positioned above the upper end surface of the storage table 103, the storage container 93 is conveyed in contact with the upper surface of the storage table 103. Since it is prevented from disappearing, work efficiency is improved.

さらに、前記貯留台103の前端部に駆動プーリ104,104を駆動回転させる駆動モータ108を設けることにより、収容容器搬送装置109が構成される。
なお、図2で示すように、貯留台103の機体左右他側の壁面のうち、収容容器載置台97から収容容器93を受ける位置に収容容器93が接触すると駆動モータ108を所定時間駆動させる載置検出スイッチ110を設けると、自動的に人参を収容した収容容器93を移動させることができるので、作業者が収容容器93を移動させる作業が省略され、作業能率が向上する。
Furthermore, a container motor 109 is configured by providing a drive motor 108 for driving and rotating the drive pulleys 104 and 104 at the front end of the storage table 103.
As shown in FIG. 2, when the storage container 93 comes into contact with the position where the storage container 93 is received from the storage container mounting base 97 on the left and right side walls of the storage base 103, the mounting motor 103 is driven for a predetermined time. When the position detection switch 110 is provided, the storage container 93 that stores the carrot can be automatically moved, so that the operation of moving the storage container 93 by the operator is omitted, and the work efficiency is improved.

駆動モータ108の駆動時間は、収容容器93一つ分が機体前方に移動する時間とする。
また、操縦者は機体の操縦に集中することができ、補助作業者は選別作業に集中することができるので、人参の引き残しが防止されると共に、人参の選別精度が向上する。
The drive time of the drive motor 108 is a time required for one container 93 to move forward.
In addition, since the operator can concentrate on maneuvering the aircraft and the auxiliary worker can concentrate on the sorting operation, it is possible to prevent the carrot from being left behind and improve the accuracy of carrot sorting.

そして、貯留台103の前端部の壁面に収容容器搬送装置109によって搬送されて来た収容容器93が接触すると駆動モータ108を停止させ、ブザーやランプなどの報知手段(図示せず)を検出する終端検出スイッチ111を設けることにより、貯留台103に収容容器93が満載されてこれ以上積めないことが自動的にわかるようになり、作業能率が向上する。   Then, when the storage container 93 transported by the storage container transport device 109 comes into contact with the wall surface of the front end portion of the storage table 103, the drive motor 108 is stopped and a notification means (not shown) such as a buzzer or a lamp is detected. By providing the end detection switch 111, it becomes automatically recognized that the storage container 103 is full of storage containers 93 and cannot be stacked any more, and the work efficiency is improved.

また、貯留台103の後端部の左右両端部に、平面視L字形状の取付ステー112,112を固着し、該取付ステー112,112の後方に突出させた端部に帯鋼で平面視コの字型に形成した支持フレーム113を固定ピン113aで固定する。そして、該支持フレーム113の左右間に複数の支持パイプ114…を設けて、商品として不適格な人参(生育不良、形状異常、傷物など)を回収する廃物回収用の廃物容器93tを配置する廃物容器支持台115を構成する。   In addition, L-shaped mounting stays 112, 112 are fixed to the left and right ends of the rear end of the storage base 103, and the ends projected from the mounting stays 112, 112 in a plan view with a steel strip. A support frame 113 formed in a U-shape is fixed by a fixing pin 113a. A plurality of support pipes 114 are provided between the left and right sides of the support frame 113 to dispose a waste collection container 93t for collecting waste ginseng (growth defects, shape abnormalities, wounds, etc.) that are ineligible as commodities. A container support 115 is formed.

上記の固定ピン113aは、最下段の廃物容器93tの下部に接触し、廃物容器93tが貯留台103に移動することを防止する。
該廃物容器支持台115の支持フレーム113は機体後方に向かう後上り傾斜姿勢とし、その傾斜角度は廃物容器93tを複数段、例えば二段積みまでは積載を許容するものに設定する。廃物容器支持台115を圃場面に対して略水平となる角度(≒0度)とすると、廃物容器93tを何個も上下方向に積み上げることが出来てしまい、重量で廃物容器支持台115が壊れてしまうおそれがある。また、機体後端に位置する廃物容器支持台115に多くの廃物容器93tを積載すると、重量バランスが機体後部に集中してしまい、機体の走行姿勢や旋回姿勢が乱されて、人参の引抜収穫位置がずれてしまうことがある。こうした問題を発生させないため、過剰に多くの廃物容器93tを積載できないよう、廃物容器支持台115を後上り傾斜姿勢としている。
The fixing pin 113 a contacts the lower part of the lowest waste container 93 t and prevents the waste container 93 t from moving to the storage table 103.
The support frame 113 of the waste container support base 115 has a rearward upward tilting posture toward the rear of the machine body, and the tilt angle is set to allow the stacking of the waste containers 93t in a plurality of stages, for example, up to two stages. If the waste container support table 115 is at an angle (≈0 degrees) that is substantially horizontal to the field, many waste containers 93t can be stacked in the vertical direction, and the waste container support table 115 is broken by weight. There is a risk that. In addition, if many waste containers 93t are loaded on the waste container support stand 115 located at the rear end of the aircraft, the weight balance is concentrated on the rear of the aircraft, and the running posture and turning posture of the aircraft are disturbed. The position may shift. In order to prevent such a problem from occurring, the waste container support base 115 is in a back-up tilt posture so that an excessively large number of waste containers 93t cannot be loaded.

なお、廃物容器支持台115には、空の、あるいは人参を収容し終えた収容容器93を載置してもよい。
そして、前記前後の回動ステー101,101の前後どちらか一方に背面視コの字型の座席支持フレーム116を挿し込んで設け、該座席支持フレーム116に選別搬送コンベア87上の人参を選別する作業者が座る補助作業座席117を取り付けることにより、収容部Gが構成される。
Note that the waste container support table 115 may be placed with an empty container or a container 93 that has received carrots.
Then, a U-shaped seat support frame 116 in a rear view is inserted into either the front or rear of the front and rear rotating stays 101, 101, and the carrots on the sorting and conveying conveyor 87 are sorted into the seat support frame 116. The accommodation part G is configured by attaching the auxiliary work seat 117 on which the worker sits.

なお、補助作業座席117は、左右方向に回転自在に取り付けてもよい。
上記構成のように、収容容器載置台97に搬送ローラ92を取り付ける複数の回転軸91a,91b,91cを設け、左右一側端部の回転軸91aを他の回転軸91b,91cよりも下方に設けたことにより、収容容器載置台97に収容容器93を設けたとき、収容容器93の左右一側端部が左右他側端部よりも下方に位置した傾斜姿勢となるので、収容容器93が搬送ローラ92によって勝手に貯留台103に移動することが防止され、人参を可能な限り収容してから貯留台103に移動させられるため、作業効率が向上する。
In addition, you may attach the auxiliary | assistant work seat 117 rotatably in the left-right direction.
As in the above configuration, a plurality of rotating shafts 91a, 91b, 91c for attaching the conveying roller 92 to the storage container mounting table 97 are provided, and the rotating shaft 91a at the left and right side ends is positioned below the other rotating shafts 91b, 91c. As a result, when the storage container 93 is provided on the storage container mounting table 97, the left and right one side ends of the storage container 93 are inclined to be positioned below the left and right other side ends. Since it is prevented by the conveyance roller 92 from moving to the storage table 103 without permission, the carrot is accommodated as much as possible and then moved to the storage table 103, so that the work efficiency is improved.

また、選別搬送コンベア87から排出される人参を受ける収容容器93が勝手に移動し、人参が圃場や機体上に落下することを防止できるので、落下の衝撃で人参が傷付くことが防止されて商品価値が維持されると共に、落下した人参を拾い集める作業が必要なく、作業者の労力が軽減される。   Moreover, since the container 93 which receives the carrot discharged from the sorting and conveying conveyor 87 can be moved without permission and the carrot is dropped on the field or the machine body, the carrot is prevented from being damaged by the impact of the fall. The product value is maintained, and the labor of picking up the carrots that have fallen is not necessary, reducing the labor of the worker.

そして、回転軸91b,91cを略同じ高さに配置したことにより、収容容器93を貯留台103に引き出す際、回転軸91bに設けた搬送ローラ92に収容容器93が載ると、回転軸91cに設けた搬送ローラ92に高低差なく移動するので、収容容器93を作業者が引き出す際の荷重が軽減されて軽い力で人参の満載された収容容器93を移動させられる。   Since the rotation shafts 91b and 91c are arranged at substantially the same height, when the storage container 93 is placed on the transport roller 92 provided on the rotation shaft 91b when the storage container 93 is pulled out to the storage base 103, the rotation shaft 91c is placed on the rotation shaft 91c. Since the transport roller 92 moves without difference in height, the load when the operator pulls out the storage container 93 is reduced, and the storage container 93 filled with carrots can be moved with a light force.

さらに、搬送ローラ92を分割した分割搬送ローラ92x,92y,92zを、回転軸91a,91b,91cにそれぞれ軸着したことにより、収容容器93の底部と接触する部分のみが回転するので、分割搬送ローラ92x,92y,92zの一つ当たりの慣性を小さくすることができ、作業者は少ない力で収容容器93を引き出せるため、作業者の労力が軽減される。   Further, since the divided conveying rollers 92x, 92y, and 92z obtained by dividing the conveying roller 92 are respectively attached to the rotation shafts 91a, 91b, and 91c, only the portion that comes into contact with the bottom portion of the storage container 93 rotates. The inertia per roller 92x, 92y, 92z can be reduced, and the operator can pull out the storage container 93 with a small force, thereby reducing the labor of the operator.

また、分割搬送ローラ92x,92y,92z同士の前後間隔、及び前後端部に位置する分割搬送ローラ92x,92zと載置支持フレーム90の前後間隔が殆ど生じない構成としたことにより、収容容器93の底部が間隔に入り込んで引っ掛かることを防止できるので、収容容器93の貯留台103への移動がスムーズになり、作業能率が向上する。   Further, since the front-rear distance between the divided transport rollers 92x, 92y, and 92z and the front-rear distance between the divided transport rollers 92x and 92z located at the front and rear end portions and the placement support frame 90 hardly occur, the storage container 93 is provided. Since the bottom portion of the container can be prevented from getting caught in the interval, the container 93 can be moved smoothly to the storage table 103, and the work efficiency can be improved.

そして、回転軸91aに回転速度を調節するブレーキ体94と調節ノブ95を設けたことにより、圃場が安定しており収容容器載置台97から貯留台103に向かって収容容器93が勝手に移動することが殆どないときは、回転軸91aの規制力を弱めて回転しやすくすることができるので、作業者はより小さい力で収容容器93を引き出せるため、作業者の労力が軽減される。   Then, by providing the rotating shaft 91a with the brake body 94 and the adjustment knob 95 for adjusting the rotation speed, the farm field is stable, and the storage container 93 moves freely from the storage container mounting base 97 toward the storage base 103. When there is almost nothing, the restriction force of the rotating shaft 91a can be weakened to facilitate rotation, so that the operator can pull out the storage container 93 with a smaller force, thereby reducing the labor of the operator.

一方、圃場に凹凸が多く、頻繁に機体が傾斜する場合等、収容容器載置台97から貯留台103に向かって収容容器93が勝手に移動しがちな場合は、回転軸91aの規制力を強めて回転しにくくすることができるので、機体が傾斜しても収容容器93は回転軸91aに軸着した搬送ローラ92に移動を規制され、勝手に貯留台103に移動することを防止されるため、人参が機体や圃場に落下して傷付くことが防止されて作物の商品価値が向上すると共に、落下した人参を拾い集める必要が無く、作業者の労力が軽減される。   On the other hand, when the storage container 93 tends to move freely from the storage container mounting base 97 toward the storage base 103, such as when the field is largely uneven and the aircraft is frequently tilted, the regulating force of the rotating shaft 91a is strengthened. Since the container 93 is restricted from moving by the transport roller 92 attached to the rotation shaft 91a even if the machine body is inclined, it is prevented from moving to the storage table 103 without permission. The carrots are prevented from falling and being damaged on the airframe or the field, thereby improving the commercial value of the crops, and it is not necessary to collect the carrots that have been dropped, thereby reducing the labor of the operator.

なお、調節ノブ95を締めて回転軸91aが全く回転しなくなるようにしてもよい。また、調節ノブ95をモータで回転する構成とし、補助作業座席117の近くにこのモータを駆動させるスイッチを設け、作業者が移動することなく調節ノブ95を回せる構成としてもよい。   The adjustment knob 95 may be tightened so that the rotation shaft 91a does not rotate at all. Further, the adjustment knob 95 may be configured to rotate with a motor, and a switch for driving the motor may be provided near the auxiliary work seat 117 so that the operator can turn the adjustment knob 95 without moving.

さらに、収容載置フレーム90に収容容器93の重量に応じて伸縮するダンパ96の一側端部を取り付けたことにより、人参の収容量がゼロ、あるいは少量の場合は収容容器93が傾斜姿勢で選別搬送コンベア87から排出される人参を受け、収容量が増えるにつれて水平に近い姿勢に変化していくので、選別搬送コンベア87から収容容器93までの人参の落下距離が短くなり、落下の衝撃で人参が傷付くことが防止され、商品価値が維持される。   Furthermore, by attaching one end of a damper 96 that expands and contracts in accordance with the weight of the storage container 93 to the storage placement frame 90, the storage container 93 is inclined when the carrot storage capacity is zero or small. Since the carrot discharged from the sorting and conveying conveyor 87 is received and the posture is changed to a horizontal posture as the accommodation amount increases, the falling distance of the carrot from the sorting and conveying conveyor 87 to the containing container 93 is shortened, and the impact of dropping The carrot is prevented from being damaged, and the commercial value is maintained.

また、収容容器93の角度を自動で変更することができるので、作業能率が向上する。
そして、貯留台103に搬送ベルト107,107:107,107と複数の搬送ローラ106,106…を設けたことにより、引き出されてきた収容容器93を自動的に機体前方に送ることができるので、作業能率が向上すると共に、作業者が収容容器93を手作業で移動させる必要が無く、作業能率が向上する。
Moreover, since the angle of the storage container 93 can be automatically changed, work efficiency improves.
And, by providing the conveyor belt 107, 107: 107, 107 and a plurality of conveyor rollers 106, 106 ... on the storage base 103, the pulled out container 93 can be automatically sent to the front of the machine body. The work efficiency is improved and the operator does not need to manually move the storage container 93, thereby improving the work efficiency.

さらに、廃物収容支持台115を構成する平面視コの字形上の支持フレーム113を、貯留台103の後端部の左右両側に取り付ける取付ステー112,112に設けたことにより、取付ステー112,112の位相が略変化しないので捻れが生じることが防止され、支持フレーム113の強度が向上する。   Further, by providing the U-shaped support frame 113 constituting the waste storage support table 115 on the left and right sides of the rear end portion of the storage table 103, the mounting stays 112, 112 are provided. Therefore, the twist is prevented from occurring, and the strength of the support frame 113 is improved.

以下、本件人参の収穫機の別実施例を説明する。
図3〜図5で示すとおり、機体フレーム1の後部で且つ左右方向の中央部付近に排葉プレート71の機体左右他側端部を回動自在に装着し、機体左右一側端部に背面視「へ」の字形状の排葉側部カバー151を設ける。該排葉側部カバー151は、前記排葉プレート71を下方回動させて機体フレーム1と略水平状態とすると、機体フレーム1の左右一側端部から外側に突出すると共に、排葉プレート71を上方回動させると残葉搬送装置70搬送終端部付近の機体左右一側を覆う位置に移動する。
Hereinafter, another embodiment of the ginseng harvester will be described.
As shown in FIGS. 3 to 5, the left and right other side ends of the leaflet plate 71 are rotatably mounted in the rear part of the body frame 1 and in the vicinity of the central part in the left and right direction, and the rear surface is mounted on the left and right side ends of the body. A leaflet side cover 151 having a shape of a “heavy” shape is provided. The leaflet side cover 151 protrudes outward from the left and right ends of the body frame 1 when the leaflet plate 71 is rotated downward to be in a substantially horizontal state with the body frame 1, and the leaflet plate 71. Is moved upward to move to a position that covers one side of the left and right sides of the machine body in the vicinity of the transfer terminal portion of the remaining leaf transfer device 70.

そして、該排葉側部カバー151の外側端部と、残葉搬送装置70の上部を覆う左右の排葉上部カバー152,152のうち、左右一側の排葉上部カバー152を、伸縮自在で且つ排葉側部カバー151を上方に付勢する力を有する引上部材153で連結する。該引上部材153は、スプリングやゴムなどの強い弾性力を有するものとする。   The left and right leaf upper cover 152 of the left and right leaf upper covers 152 and 152 covering the outer end of the leaf leaf side cover 151 and the upper part of the remaining leaf transport device 70 can be extended and retracted. And it connects with the raising member 153 which has the force which urges | biases the leaf | leaf side cover 151 upward. The pull-up member 153 has a strong elastic force such as a spring or rubber.

上記構成としたことにより、排葉プレート71を上方回動させると排葉シュータになると共に、下方回動させると排葉回収台になることにより、茎葉部の量等の作業条件に合わせて排葉プレート71をシュータとするか排葉回収台とするかを選択することができるので、作業条件の変化に適応しやすく、作業能率が向上する。   With the above configuration, when the leaf removal plate 71 is rotated upward, it becomes a leaf leaf shooter, and when it is rotated downward, it becomes a leaf leaf collection table, so that the waste leaf plate 71 is discharged in accordance with the working conditions such as the amount of leaves and leaves. Since it is possible to select whether the leaf plate 71 is a shooter or a leaf collection table, it is easy to adapt to changes in work conditions and work efficiency is improved.

また、排葉プレート71の外側端部に排葉側部カバー151を設けたことにより、シュータとしたときには排葉側部カバー151が残葉搬送装置70の搬送終端部付近の機体左右一側を覆うので、残葉搬送装置70から排出された茎葉部が風に飛ばされても機体左右一側から圃場に落下することが防止されるため、未収穫の人参の上に切断された茎葉部が載ることがなく、挟持引抜作業時に引抜搬送装置24が人参を引き抜き損なうことや、茎葉部が詰まって引抜搬送装置24が停止することが防止される。   Further, by providing the leaflet side cover 151 at the outer end portion of the leaflet plate 71, when the shooter is used, the leaflet side cover 151 is positioned on the left and right sides of the machine body near the conveyance terminal portion of the remaining leaf conveyance device 70. Since it covers, it is prevented that the foliage discharged from the remaining leaf transport device 70 is blown by the wind, so that it is prevented from falling to the field from the left and right sides of the machine body. This prevents the pulling / conveying device 24 from failing to pull out the carrot at the time of the pinching / pulling operation, or preventing the pulling / conveying device 24 from stopping due to clogging of the foliage.

一方、排葉プレート71を排葉回収台としたときは、排葉側部カバー151が機体左右一側の壁となるので、排葉プレート71上の端部寄りに落下した茎葉部が圃場に落下することが防止され、未収穫の人参の上に切断された茎葉部が載ることが防止される。   On the other hand, when the leaf removal plate 71 is used as a leaf collection base, the leaf removal side cover 151 serves as a wall on the left and right sides of the machine body. It is prevented from falling and the cut leaves are prevented from being placed on unharvested carrots.

そして、該排葉側部カバー151の外側端部と左右一側の排葉上部カバー152を引上部材153で連結したことにより、排葉プレート71をシュータとして茎葉部を圃場に移動させるとき、作業者が軽い力で排葉プレート71を持ち上げることができるので、作業者の労力が軽減される。   Then, by connecting the outer end portion of the leaf removal side cover 151 and the leaf upper cover 152 on the left and right sides with a lifting member 153, when the leaf portion is moved to the field using the leaf removal plate 71 as a shooter, Since the worker can lift the leaf removal plate 71 with a light force, the labor of the worker is reduced.

さらに、排葉プレート71の回動支点を機体左右他側端部としたことにより、排葉プレート71を上方回動させると機体左右一側から左右他側に向かって下方傾斜する姿勢となるので、茎葉部がクローラ6L,6Rの左右間、または右側のクローラ6R上に落下する。   Further, since the pivoting fulcrum of the leaflet plate 71 is the left and right side end of the machine body, when the leaflet plate 71 is pivoted upward, it is inclined downward from the left and right side of the machine body toward the other side of the left and right sides. The foliage falls between the left and right of the crawlers 6L and 6R or on the right crawler 6R.

クローラ6L,6Rの左右間に茎葉部を落とすと、機体フレーム1の下方を通過するので、大量の茎葉部を圃場に纏めて置いておくことができ、後工程の回収作業の能率が向上する。   If the foliage is dropped between the left and right of the crawlers 6L and 6R, the foliage passes through the lower part of the machine body frame 1, so that a large amount of foliage can be put together in the field, and the efficiency of the recovery process in the subsequent process is improved. .

一方、右側のクローラ6R上に茎葉部を落としていくと、茎葉部はクローラ6Rの走行に伴い前方に移動して圃場に落ち、クローラ6Rに踏み潰される。このとき、茎葉部は潰されたり引き千切られたりしながら土中に埋め込まれるため、土中の菌類や細菌によって分解され、圃場の養分となり、土質を向上させることが可能となる。   On the other hand, when the foliage part is dropped on the crawler 6R on the right side, the foliage part moves forward as the crawler 6R travels, falls to the field, and is crushed by the crawler 6R. At this time, the foliage is embedded in the soil while being crushed or shredded, so that it is decomposed by fungi and bacteria in the soil, becomes nutrients in the field, and improves the soil quality.

なお、図2、図5及び図21に記載している通り、上記構成に加えて、後側フレーム120と排葉プレート71の機体前側端部を排葉昇降シリンダ154で連結し、該排葉昇降シリンダ154を伸縮操作する排葉操作スイッチ155を操縦パネル12に設ける構成としてもよい。   2, 5 and 21, in addition to the above configuration, the rear frame 120 and the front end of the leaf plate 71 are connected by a leaf lift cylinder 154, and the leaf It is good also as a structure which provides the control panel 12 with the leaf operation switch 155 which expands / contracts the raising / lowering cylinder 154. FIG.

上記構成とすると、作業者は排葉プレート71上の茎葉部を圃場に移動させる際、人参収穫機の走行を停止させ、一旦降車して機体後部に移動し、排葉プレート71を上方回動させる必要がなくなるので、人参の収穫をしながら茎葉部の移動が可能となり、作業能率が向上すると共に、作業者の労力が大幅に軽減される。   With the above configuration, when the operator moves the foliage part on the leaf plate 71 to the field, the operator stops the carrot harvester, gets off the vehicle, moves to the rear part of the machine body, and rotates the leaf plate 71 upward. Therefore, it is possible to move the foliage while harvesting carrots, improving the work efficiency and greatly reducing the labor of the worker.

しかしながら、機体を操縦する作業者は、圃場端までの距離や人参の植生状態を確認し続ける必要があり、排葉プレート71にどの程度の量の茎葉部が積載されているかを把握することが困難である。茎葉部の積載量を確認するべく、走行速度を減速させたり、圃場端まで十分な距離がある地点で積載量を確認してもよいが、作業能率や操作性、及び人参の収穫精度を高めるには、作業者は後ろを振り返るべきではない。   However, it is necessary for the operator who controls the aircraft to continue to check the distance to the end of the field and the vegetation state of the carrot, and can grasp how much foliage is loaded on the leaf plate 71. Have difficulty. In order to check the loading capacity of the foliage, the traveling speed may be reduced or the loading capacity may be checked at a point where there is a sufficient distance to the end of the field, but the work efficiency, operability, and carrot harvesting accuracy are improved. The worker should not look back.

上記の問題を解消すべく、図22及び図23で示すとおり、排葉プレート71に重量検知センサ156を設け、茎葉部の積載量を検知する(S01)構成とし、該重量検知センサ156が所定重量、例えば茎葉部の総重量が2kgを超えると(S02)、排葉昇降シリンダ154に収縮信号が発信され(S03)、排葉プレート71が自動的にシュータになる構成としてもよい。   In order to solve the above problems, as shown in FIGS. 22 and 23, a weight detection sensor 156 is provided on the leaflet plate 71 to detect the loading amount of the foliage (S01), and the weight detection sensor 156 is a predetermined value. When the weight, for example, the total weight of the foliage part exceeds 2 kg (S02), a contraction signal is transmitted to the leaf raising / lowering cylinder 154 (S03), and the leaf leaf plate 71 may automatically become a shooter.

上記構成とすることにより、茎葉部が所定重量積載されたときに自動的に圃場に移動されるので、作業者は茎葉部の積載量を気にすることなく人参の収穫作業を行うことができるので、人参の抜き残しが減少すると共に、高速で移動することができるので、作業能率が向上する。   With the above configuration, when the foliage portion is loaded with a predetermined weight, it is automatically moved to the field, so that the operator can perform the carrot harvesting operation without worrying about the loading amount of the foliage portion. As a result, the remaining amount of ginseng is reduced and the vehicle can be moved at a high speed, so that the work efficiency is improved.

また、排葉プレート71上に茎葉部が許容量以上積載され、風や機体の振動が加わると茎葉部が排葉側部カバー151を超えて圃場に落下することを防止できるので、未収穫の人参の上に茎葉部が降りかかることが防止される。   Moreover, since the foliage portion is loaded on the leaf removal plate 71 more than an allowable amount, and the wind and the vibration of the airframe are added, the leaf portion can be prevented from falling over the leaf leaf side cover 151 and falling into the field. The foliage is prevented from falling on the carrot.

なお、重量検知センサ156が排葉昇降シリンダ154を収縮させる重量は、作業者が人参の品種(茎葉部の量が異なる)や作業条件(風の強弱、圃場に移動させるタイミング)に合わせて変更可能なものとする。   Note that the weight by which the weight detection sensor 156 contracts the leaf lifting / lowering cylinder 154 is changed according to the type of carrot (the amount of foliage varies) and the working conditions (wind intensity, timing to move to the field). Be possible.

自動的に茎葉部が圃場に移動されていると、茎葉部の排出位置によっては回収作業の能率が低下する可能性がある。作業者が茎葉部を移動させるタイミングを知りつつ、圃場に移動させるタイミングは自分で決められる構成としては、重量検知センサ156が所定重量を検知すると(S04,S05)作動するブザー157を設け、音声で作業者に茎葉部を移動させるタイミング(S06,S10)が来たことを報知する構成としてもよい。   If the foliage is automatically moved to the field, the efficiency of the recovery operation may be reduced depending on the discharge position of the foliage. As a configuration in which the worker can determine the timing for moving the foliage part while knowing the timing for moving the foliage part, a buzzer 157 that operates when the weight detection sensor 156 detects a predetermined weight (S04, S05) is provided, and a voice is transmitted. Thus, the operator may be notified that the timing (S06, S10) for moving the foliage has arrived.

上記構成により、作業者は茎葉部を排葉プレート71から圃場に移動させるタイミングに到達していることを音声で把握することができるので、任意のタイミングで排葉操作スイッチ155を操作すればよく、作業能率や操作性が大幅に向上する。   With the above-described configuration, the operator can grasp by voice that the stem and leaf portion has reached the timing for moving the leaf and leaf portion from the leaf leaf plate 71 to the field. Therefore, it is only necessary to operate the leaf leaf operation switch 155 at any timing. Work efficiency and operability are greatly improved.

なお、重量検知センサ156がブザー157を作動させる重量を、茎葉部の移動が速やかに必要となる重量よりも若干軽く設定しておくと、茎葉部の移動を行う位置まで移動する間に茎葉部がはみ出して圃場に落ちることを防止しやすくなる。このとき、茎葉部がさらに積載されて重量が増し、排出すべき重量になるとブザー157の音声発信パターンが変更される構成とすると、作業者が現在の茎葉部の積載量を判断しやすくなり、いっそう茎葉部を圃場に移動させるタイミングが掴みやすくなるので、作業能率が向上する。   In addition, if the weight by which the weight detection sensor 156 operates the buzzer 157 is set to be slightly lighter than the weight at which the movement of the foliage part is required quickly, the foliage part is moved to the position where the foliage part is moved. It is easy to prevent the spilling out and falling into the field. At this time, if the structure is such that the sound transmission pattern of the buzzer 157 is changed when the weight of the foliage is further increased and the weight to be discharged is reached, the operator can easily determine the current amount of foliage. Since it becomes easier to grasp the timing for moving the foliage part to the field, the work efficiency is improved.

上記のブザー157の発信パターンは、茎葉部の圃場への移動を推奨する重量を検知した(S04,S05)第1段階(S06)では短い音を1回、または数回発信し、茎葉部を速やかに圃場に移動させるべき重量を検知した(S08,S09)第2段階(S10)では長い音を排葉操作スイッチ155が操作されるまで発信する(S07,S11)、等の方式が考えられるが、作業者が気付きやすい方式であれば、どのようなパターンを選択してもよい。   The transmission pattern of the buzzer 157 detects the weight recommending the movement of the foliage to the field (S04, S05). In the first stage (S06), a short sound is transmitted once or several times, and the foliage is transmitted. In the second stage (S10) where the weight to be quickly moved to the field is detected (S08, S09), a long sound is transmitted until the leaf operation switch 155 is operated (S07, S11). However, any pattern may be selected as long as the operator can easily recognize the pattern.
