Description

本発明は、野菜等の苗を圃場に植え付けると共に、苗の植付位置に薬剤を供給する移植機に関するものである。 The present invention relates to a transplanter for planting seedlings such as vegetables in a field and supplying a drug to a planting position of the seedlings.

引用文献1に記載のとおり、作業者が投入する苗を搬送し、苗の植付装置に供給する位置で落下させる苗供給装置を備え、苗供給装置よりも機体前側に薬剤を苗の植付位置の近傍に供給する苗供給装置を備える移植機が存在する。 As described in Cited Document 1, a worker is provided with a seedling supply device that conveys seedlings to be input and drops at a position where the seedlings are supplied to the planting device. There are transplanters equipped with seedling feeders that feed near the location.

また、引用文献2に記載のとおり、苗供給装置の前方に配置し、植付装置の苗の植付位置までの前後間隔が狭い苗供給装置を備える移植機が存在する。 Further, as described in Cited Document 2, there is a transplanter that is provided in front of the seedling feeding device and that includes a seedling feeding device that has a narrow front-rear distance to the seedling planting position of the planting device.

また、引用文献3に記載のとおり、作業者が投入する苗を搬送し、苗の植付装置に供給する位置で落下させる苗供給装置を備え、苗供給装置よりも機体後側に苗供給装置を備える移植機が存在する。 Further, as described in Cited Document 3, a seedling supply device is provided which conveys the seedlings to be input by the worker and drops the seedlings at a position for supplying the seedling planting device, and the seedling supply device is on the rear side of the machine body with respect to the seedling supply device. There is a transplanter equipped with.

上記により、植え付けられた苗、及び苗の植付位置の周辺に薬剤を供給することができるので、害虫による苗の食害や、菌等による病害の発生を抑制でき、苗の生育が安定する。 According to the above, the drug can be supplied to the planted seedlings and the vicinity of the planting position of the seedlings, so that the feeding damage of the seedlings caused by the pests and the occurrence of the disease caused by the fungi can be suppressed, and the growth of the seedlings is stabilized.

特開2010−263867号公報JP, 2010-263867, A 特開2014− 45752号公報JP, 2014-45752, A 特許5780335号公報Japanese Patent No. 5780335

しかしながら、引用文献1の移植機は、薬剤供給装置から植付装置の植付位置までの前後間隔が大きく、繰り出された薬剤が供給ホースの終端部から放出されるまでに時間を要する。従って、苗の植付位置から離れた位置に薬剤が供給されてしまい、十分な殺虫、殺菌作用が得られず、苗の生育が悪くなることや、苗が立ち枯れてしまうことがある。 However, in the transplanter of the cited document 1, the front-rear distance from the drug supply device to the implanting position of the implanting device is large, and it takes time for the dispensed drug to be discharged from the terminal end of the supply hose. Therefore, the chemicals are supplied to a position away from the planting position of the seedlings, sufficient insecticidal and bactericidal actions cannot be obtained, the growth of the seedlings may be deteriorated, and the seedlings may die.

また、前後間隔が大きいことにより、供給ホースを比較的緩やかな後下がり傾斜姿勢で配置せざるを得ず、薬剤の移動速度が遅くなり、苗から離れた位置に薬剤が供給されることや、多少の供給ホースの撓みにより薬剤が移動できなくなり、薬剤が供給されなくなる問題が発生する。 Also, due to the large front-rear spacing, the supply hose has to be arranged in a relatively gentle rearward and downward inclined posture, the moving speed of the drug is slowed, and the drug is supplied to a position distant from the seedling, Due to some bending of the supply hose, the medicine cannot be moved, and there is a problem that the medicine cannot be supplied.

引用文献2の発明では、薬剤供給装置と植付装置の前後間隔が小さいので、上記の問題を解消することができる。しかしながら、薬剤供給装置の後方は苗供給装置、前方はエンジンやミッションケースを覆うカバー、左右は走行伝動ケースや走行輪、苗載せ台が配置されているので、作業者が薬剤供給装置に接近しにくく、薬剤の投入や排出が行いにくく、作業能率が低下する問題がある。 In the invention of Cited Document 2, since the front-rear distance between the medicine supply device and the planting device is small, the above problem can be solved. However, since the seedling feeder is behind the drug feeder, the cover covers the engine and the mission case in the front, and the traveling transmission case, running wheels, and seedling stand are arranged on the left and right, so workers can approach the drug feeder. However, there is a problem that it is difficult to input and discharge the medicine, and the work efficiency is reduced.

引用文献3の発明では、薬剤供給装置が苗供給装置よりも機体後方に配置されており、作業者は機体の後方または後部の側方から薬剤供給装置に接近しやすい。また、苗の植付位置にも比較的前後間隔が小さい位置に配置されるので、上記の問題を解消し得る。 In the invention of Cited Document 3, the drug supply device is arranged rearward of the machine body with respect to the seedling supply device, and an operator easily approaches the drug supply device from the rear side or rear side of the machine body. Further, since the planting position of the seedlings is arranged at a position where the front-rear distance is relatively small, the above problem can be solved.

しかしながら、薬剤供給装置自体が重量物であり、ここに薬剤を投入するとさらに重量が増すので、機体後部に重量が集中し、機体前側が浮き上がりやすくなる。これにより、植付装置の植付深さが設定と異なる深さになることや、植付姿勢が圃場に対して略垂直ではなく、前方または後方に傾斜した姿勢になることがあり、苗の植付精度が低下する問題がある。 However, since the medicine supplying device itself is a heavy object and the weight is further increased when the medicine is injected into the medicine supplying apparatus, the weight concentrates on the rear part of the machine body, and the front side of the machine body is easily lifted. As a result, the planting depth of the planting device may be different from the set depth, and the planting posture may not be substantially perpendicular to the field but may be a posture inclined forward or backward. There is a problem that the planting accuracy is reduced.

そこで、本発明の課題は、苗の植付位置に確実に薬剤を供給できると共に、機体の重量バランスを損ないにくい移植機を提供することである。 Then, the subject of this invention is providing the transplanter which can supply a chemical|medical agent to the planting position of a seedling reliably, and is hard to impair the weight balance of a body.

以下、図面に基づき、本発明の好ましい実施の形態について説明する。 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

図1及び図2には、本実施形態の移植機の側面図と平面図を示す。この移植機の前進方向に向かって左右方向をそれぞれ左、右といい、前進方向と後進方向をそれぞれ前、後という。 1 and 2 show a side view and a plan view of the transplanter of the present embodiment. The left and right directions are referred to as left and right, respectively, and the forward and backward directions are referred to as front and rear, respectively, in the forward direction of the transplanter.

この移植機1は、前部にエンジン2及びミッションケース3と走行車輪としての左右一対の前輪4及び後輪5と、後部に植付装置7、苗供給装置6、鎮圧輪8及び操縦ハンドル9とを備えて構成されている。 This transplanter 1 has an engine 2 and a mission case 3 and a pair of left and right front wheels 4 and rear wheels 5 as traveling wheels at a front part, and a rearing part with a planting device 7, a seedling supply device 6, a pressure suppression wheel 8 and a steering wheel 9. And is configured.

この移植機1は、機体が圃場内の畝Uをまたぐように、前輪4及び後輪5が畝間を走行し、畝の上面の左右幅方向における中央位置に植付装置7により移植対象物を植え付けていくようになっている。 In this transplanter 1, the front wheels 4 and the rear wheels 5 travel between the ridges so that the body crosses the ridges U in the field, and the transplanting device 7 is used to place an object to be transplanted at the center position in the left-right width direction on the upper surface of the ridges. It is designed to be planted.

前記苗植付装置7が苗を植え付けるときは、土壌に突き刺さって進入し、苗を開放すべく開くので、苗の植付部分は、土が押し上げられることになる。これにより、植え付けられた苗の周囲には隙間ができると共に、周囲の土は解されているので、このままでは苗が土に保持されず、風等の影響で倒れて、抜けてしまうことがある。 When the seedling planting device 7 is planting seedlings, it penetrates into the soil and enters to open the seedlings, so that the seedlings are pushed up by the soil. As a result, a gap is created around the planted seedlings and the surrounding soil is unraveled, so the seedlings may not be retained in the soil as they are, and may fall due to the influence of the wind or the like and fall out. ..

これを防止すべく、植え付けられた苗の周囲に押し上げられた土を上方から苗に寄せると共に、軽く押し固めるための左右一対の覆土鎮圧輪8,8を、圃場面との接地で回転可能に設ける。 In order to prevent this, the soil pushed up around the planted seedlings is brought to the seedlings from above, and a pair of left and right cover soil suppression wheels 8 and 8 for lightly compacting can be rotated by contact with the field scene. Set up.

該左右一対の覆土鎮圧輪8,8はアルミ合金等の軽金属で構成する。これにより、塩化ビニル等の合成樹脂で構成するものよりも耐久性が向上すると共に、重量が多少なりとも重くなるので、土をよりしっかりと押し固めて、苗の倒伏を防止できる。 The pair of left and right cover soil suppression wheels 8 and 8 are made of a light metal such as an aluminum alloy. As a result, the durability is improved and the weight becomes heavier than that made of a synthetic resin such as vinyl chloride, so that the soil can be pressed more firmly and the lodging of the seedlings can be prevented.

前記ミッションケース3の左右端には該ミッションケース3に対して回動可能な走行エクステンションケース10を左右それぞれ設け、左右の走行エクステンションケース10のそれぞれの端部に走行チェーンケース11を取り付けている。したがって、エンジン2から入力されるミッションケース3内の動力を走行チェーンケース11内に伝動する構成となっている。 At the left and right ends of the mission case 3, traveling extension cases 10 which are rotatable with respect to the mission case 3 are provided respectively on the left and right sides, and traveling chain cases 11 are attached to the respective end portions of the left and right traveling extension cases 10. Therefore, the power in the mission case 3 input from the engine 2 is transmitted to the traveling chain case 11.

走行チェーンケース11の回動先端部の左右外側には、走行車輪である左右一対の後輪5をそれぞれ取り付け、この左右一対の後輪5の駆動により機体が走行するようになっている。したがって、ミッションケース3は、走行車輪としての後輪5に伝動する伝動装置となっている。 A pair of left and right rear wheels 5, which are traveling wheels, are attached to the left and right outer sides of the rotating tip of the traveling chain case 11, and the vehicle body is driven by driving the pair of left and right rear wheels 5. Therefore, the mission case 3 is a transmission device that is transmitted to the rear wheels 5 as traveling wheels.

一方、エンジン載置台の下部には左右方向に延びる前輪支持フレーム12を前後方向のローリング軸13回りに回動可能に設け、この前輪支持フレーム12の左右両端部に前輪4を取り付けている。 On the other hand, a front wheel support frame 12 extending in the left-right direction is provided rotatably around a rolling shaft 13 in the front-rear direction at the lower part of the engine mounting table, and front wheels 4 are attached to both left and right ends of the front wheel support frame 12.

また、ミッションケース3の後端の左右方向に配置された横フレーム14の後部には、機体の左右方向右寄りの位置に延びる主フレーム15を設けている。該主フレーム15の後端部には操縦ハンドル9を設け、この操縦ハンドル9が主フレーム15及び、横フレーム14を介してミッションケース3に支持されている。 Further, at the rear of the lateral frame 14 arranged in the left-right direction at the rear end of the mission case 3, there is provided a main frame 15 extending to the right side in the left-right direction of the machine body. A steering handle 9 is provided at the rear end of the main frame 15, and the steering handle 9 is supported by the mission case 3 via the main frame 15 and the lateral frame 14.

また、ミッションケース3の後部で左右方向の中央には、油圧昇降シリンダ16を設けている。この油圧昇降シリンダ16は、ミッションケース3に取り付けられた油圧切替バルブ部17に固着して設けられ、ミッションケース3に取り付けられた油圧ポンプからの油圧を切り替える油圧切替バルブ部17に備えられた昇降操作バルブを操作することにより作動する。 A hydraulic lift cylinder 16 is provided at the rear center of the transmission case 3 in the left-right direction. The hydraulic lifting cylinder 16 is fixedly provided to the hydraulic switching valve unit 17 mounted on the mission case 3, and is mounted on the hydraulic switching valve unit 17 switching the hydraulic pressure from the hydraulic pump mounted on the transmission case 3. It operates by operating the operating valve.

また、油圧昇降シリンダ16のシリンダロッド端には左右に延びる横杆19を設け、この横杆19の左右端部にそれぞれ後輪昇降ロッド20,21を枢着し該ロッド20,21の他端をそれぞれの走行エクステンションケース10に取り付けられた上側アーム10aに枢着して、横杆19と走行エクステンションケース10とが連結された構成となっている。 Further, a horizontal rod 19 extending to the left and right is provided at the cylinder rod end of the hydraulic lifting cylinder 16, and rear wheel lifting rods 20 and 21 are pivotally attached to the left and right ends of the horizontal rod 19, respectively, and the other ends of the rods 20 and 21. Is pivotally attached to the upper arm 10a attached to each traveling extension case 10, and the horizontal rod 19 and the traveling extension case 10 are connected to each other.

したがって、油圧昇降シリンダ16の伸縮により横杆19、後輪昇降ロッド20,21を介してミッションケース3の左右の出力軸回りに走行チェーンケース11が回動され、該走行チェーンケース11の回動により後輪5が上下して機体が昇降する構成となっている。 Therefore, the traveling chain case 11 is rotated around the left and right output shafts of the transmission case 3 through the horizontal rod 19 and the rear wheel raising and lowering rods 20 and 21 by the expansion and contraction of the hydraulic lifting cylinder 16, and the traveling chain case 11 is rotated. Thus, the rear wheel 5 moves up and down, and the machine body moves up and down.

また、左側の後輪昇降ロッド20が伸縮するように該ロッド20の中途部に油圧ポンプからの油圧により作動する水平用油圧シリンダ22を設けており、該水平用油圧シリンダ22の伸縮により右側の後輪5の上下位置に対して左側の後輪5を上下させて、畝の谷部の凹凸に関係なく機体を左右水平に維持できるようになっている。 In addition, a horizontal hydraulic cylinder 22 that is operated by hydraulic pressure from a hydraulic pump is provided in the middle of the left rear wheel lifting rod 20 so that the left rear wheel lifting rod 20 expands and contracts. The left rear wheel 5 is moved up and down with respect to the vertical position of the rear wheel 5 so that the body can be maintained horizontally regardless of the unevenness of the valley portion of the ridge.

本実施の形態の植付装置7は、野菜苗等の移植対象物を1個ずつ圃場の畝部に植付けるべく、ミッションケース3内からの動力がミッションケース3の後側に設けた植付伝動ケース24と、その植付伝動ケース24に取り付けられた植付装置駆動ケース25aを介して伝達され作動するようになっている。 The planting device 7 according to the present embodiment is a planting device in which power from inside the mission case 3 is provided on the rear side of the mission case 3 in order to plant one transplant target object such as a vegetable seedling in the ridge of the field. The transmission case 24 and the planting device drive case 25a attached to the planting transmission case 24 are transmitted to operate.

植付装置7は、先端が尖ったカップ状の植付具72と該植付具72を昇降させるべく作動するリンク機構75などで構成される。植付具72の先端は、植付具72の昇降動作によって、図1に示すとおり、概ね楕円形の軌跡を描いて図中の矢印方向に繰り返し作動する。 The planting device 7 includes a cup-shaped planting tool 72 having a sharp tip, a link mechanism 75 that operates to move the planting tool 72 up and down, and the like. As shown in FIG. 1, the tip end of the planting tool 72 draws a substantially elliptical locus as shown in FIG. 1 and is repeatedly operated in the arrow direction in the figure.

そして、移植対象物である苗用の載置台30は、図1、図2及び図7、図8に示すとおり、苗供給装置6よりも前側に設ける側面視L字形状の左右の苗枠フレーム31,31と、該苗枠フレーム31,31よりも機体前側で機体上方に立接される左右の苗枠支柱32,32の上方に配置される。また、該載置台30の左右方向の中心位置は、前記苗供給装置6の中心部に設ける供給回転軸66fの直線上であり、且つ左右の後輪5,5の左右中央位置よりも機体左右他側(機体左側)に偏倚する位置に配置する。 As shown in FIG. 1, FIG. 2, FIG. 7, and FIG. 8, the placing table 30 for the seedlings to be transplanted is provided on the front side of the seedling feeding device 6 and has left and right seedling frame frames having an L-shape in a side view. 31 and 31 and the left and right seedling frame support columns 32 and 32 that are erected on the upper side of the machine body on the front side of the machine body with respect to the seedling frame frames 31 and 31. Further, the center position of the mounting table 30 in the left-right direction is on the straight line of the supply rotation shaft 66f provided in the central portion of the seedling supply device 6, and in the left-right center position of the machine rather than the left-right center position of the left and right rear wheels 5, 5. Place it in a position that is offset to the other side (left side of the machine).

前記左右の苗枠フレーム31,31のうち、機体前方に突出する部分は、機体上方に向けて機体前側に向かうほど上方に位置する傾斜姿勢とし、積載する苗を収容した苗箱38を傾斜により機体後側に移動させ、苗を取り出す位置が作業者に近くなる構成とする。 Of the left and right seedling frame frames 31, 31, the portions projecting toward the front of the machine body are in an inclined posture that is positioned higher toward the front side of the machine body toward the upper side of the machine body, and the seedling box 38 accommodating the seedlings to be loaded is inclined. It will be moved to the rear side of the machine, and the position where the seedlings are taken out will be close to the operator.

また、前記載置台30は、左右方向に長い線材で構成する第1載置枠33と、該第1載置枠33の左右幅内で、機体前後方向に突出する線材で構成する第2載置枠34を組み合わせて構成する。なお、第1載置枠33は、第2載置枠34の左右他側よりも左右一側(機体右側)の突出量を大きくすると共に、左右一側の端部の前後角部は、直角でなく後傾または前傾するテーパ部を形成する。このとき、第1載置枠33の左右一側端部及び左右他側端部は、前記左右の前輪4,4及び後輪5,5よりも機体外側に位置する。 In addition, the mounting table 30 includes a first mounting frame 33 configured by a wire material that is long in the left-right direction and a second mounting frame configured by a wire material that protrudes in the front-rear direction of the machine body within the left-right width of the first mounting frame 33. It is configured by combining the placing frames 34. In addition, the first mounting frame 33 has a larger protrusion amount on one left and right side (right side of the machine body) than on the other side of the second mounting frame 34, and the front and rear corners of the one left and right side end have a right angle. Instead, a taper portion that tilts backward or forward is formed. At this time, the left and right one-side ends and the left and right other-side ends of the first mounting frame 33 are located outside the vehicle body with respect to the left and right front wheels 4, 4 and rear wheels 5, 5.

そして、前記第1載置枠33の左右他側で、且つ外側端部よりも機体内側には、前後方向の回動支軸35a,35bを設け、該前後の回動支軸35a,35bを回動支点として、機体外側に向かって展開可能な回動苗枠36を設ける。前記前後の回動支軸35a,35bのうち、機体後側に設ける後側の回動支軸35bは、ボルト等の締め込みにより皿バネ等を圧縮することや、ダブルナットにより前記回動苗枠36の回動に要する力を増減させる荷重調節機構35cを有するものとする。 Further, on the other side of the first mounting frame 33 on the left and right sides, and inside the machine body with respect to the outer end portion, rotation support shafts 35a, 35b in the front-rear direction are provided, and the front and rear rotation support shafts 35a, 35b are provided. A rotating seedling frame 36 that can be deployed toward the outside of the machine body is provided as a rotation fulcrum. Of the front and rear rotation support shafts 35a and 35b, the rear rotation support shaft 35b provided on the rear side of the machine body is used to compress a disc spring or the like by tightening bolts or the like, or to rotate the rotation seedling by a double nut. It is assumed to have a load adjusting mechanism 35c that increases or decreases the force required to rotate the frame 36.

前記回動苗枠36を機体外側に回動させるとき、前記第1載置枠33の左右他側端部は、平面視で回動苗枠36の機体内側端部と接触する位置にあるので、その位置で回動苗枠36の回動が規制される。従って、回動苗枠36が圃場に向かう下り傾斜姿勢になるまで回動せず、積載した苗の落下が防止される。 When the rotating seedling frame 36 is rotated to the outside of the machine body, the left and right other-side ends of the first mounting frame 33 are in positions where they are in contact with the ends of the rotating seedling frame 36 inside the machine body in plan view. The rotation of the rotating seedling frame 36 is restricted at that position. Therefore, the rotating seedling frame 36 does not rotate until it is in a downwardly inclined posture toward the field, and falling of the loaded seedlings is prevented.

上記により、載置台30及び苗供給装置6の機体左右他側で、且つ左右他側の後輪5の後方に立って載置台30上に載置した苗を取って苗供給装置6に供給する作業者が、回動苗枠36の回動に必要な力の強弱を、苗の供給作業位置で行うことができる。従って、力の強弱調節の度に苗の供給作業位置を離れる必要が無く、作業能率が向上する。 According to the above, the seedlings placed on the placing table 30 are supplied to the seedling feeding device 6 while standing on the left and right other sides of the mounting table 30 and the seedling feeding device 6 and behind the rear wheels 5 on the left and right other sides. The operator can adjust the strength of the force required for the rotation of the rotating seedling frame 36 at the seedling supplying work position. Therefore, it is not necessary to leave the seedling supplying work position each time the strength of the force is adjusted, and the work efficiency is improved.

また、回動苗枠36を回動可能に第1載置枠33の左右他側で、且つ回動させると左右他側の後輪5よりも機体外側に突出する位置に設けたことにより、苗の積載量が増加し、苗の補充作業の頻度を減らすことができると共に、回動苗枠36の展開時の位置を作業者が苗を取り易い位置とすることができるので、作業能率が向上する。 Further, since the rotating seedling frame 36 is rotatably provided on the left and right other sides of the first mounting frame 33, and when it is rotated, it is provided at a position projecting to the outside of the body with respect to the left and right other side rear wheels 5, Since the load of seedlings can be increased, the frequency of seedling replenishing work can be reduced, and the position of the rotating seedling frame 36 at the time of deployment can be set to a position where an operator can easily pick up seedlings, thus improving work efficiency. improves.

これに加えて、回動苗枠36を載置台30の上方に向けて回動させると、回動苗枠36が載置台30の機体外側から突出しないので、機体の左右幅のコンパクト化が図られる。 In addition, when the rotating seedling frame 36 is rotated toward the upper side of the mounting table 30, the rotating seedling frame 36 does not project from the outside of the mounting table 30. Therefore, the lateral width of the body can be reduced. To be

前記回動苗枠36は、前記前後の回動支軸35a,35bに装着される線材で構成する平面視コの字形状の第1回動枠36aと、該第1回動枠36aの左右幅内に設けられ、機体前後方向に突出する線材で構成する第2回動枠36bで構成する。該第2載置枠34と第2回動枠36bは、前後端部を機体上方に向けて屈曲させ、積載する苗を収容した苗箱38を受ける苗箱受部37を各々形成する。 The rotating seedling frame 36 includes a first rotating frame 36a having a U-shape in a plan view, which is composed of wires attached to the front and rear rotating support shafts 35a and 35b, and left and right sides of the first rotating frame 36a. The second rotation frame 36b is formed within the width and is formed of a wire rod that protrudes in the longitudinal direction of the machine body. The second placing frame 34 and the second rotating frame 36b are bent at their front and rear ends toward the upper side of the machine body to form seedling box receiving portions 37 for receiving the seedling boxes 38 containing the seedlings to be loaded.

前記第2載置枠34と第2回動枠36bは、前記第1載置枠33及び第1回動枠36aの前後端部よりも機体前側及び後側に突出させるものとし、機体後側の突出量を機体前側よりも大きくする。また、第2載置枠34と第2回動枠36bの機体前側及び後側への突出量は同一とし、載置台30と回動苗枠36とで苗箱38の移動に違いが生じない構成とし、苗箱38の移動や取り出しを行いやすくし、作業能率を構成されるものとする。 The second mounting frame 34 and the second rotating frame 36b are projected to the front side and the rear side of the body with respect to the front and rear end portions of the first mounting frame 33 and the first rotating frame 36a. The protrusion amount of is larger than the front side of the machine. Further, the protrusion amounts of the second placing frame 34 and the second rotating frame 36b to the front side and the rear side of the machine body are the same, and there is no difference in the movement of the seedling box 38 between the placing table 30 and the rotating seedling frame 36. In this configuration, the seedling box 38 can be easily moved and taken out, and the work efficiency is configured.

これにより、積載した苗箱38が機体後側寄りに移動し、苗の載置面を作業者側に向けるので、作業者が苗を取り出しやすく、作業能率が向上する。 As a result, the loaded seedling box 38 moves toward the rear side of the machine body and the placement surface of the seedling faces the operator side, so that the operator can easily take out the seedling and the work efficiency is improved.

また、図2及び図8に示すとおり、機体左右他側の前記苗枠フレーム31の後部側と、前記後側の回動支軸35bとを、補強プレート39で連結する。該補強プレート39は、機体左右一側の前記苗枠フレーム31の前部側と、前記前側の回動支軸35aを連結するものを設けてもよいが、前記回動苗枠36のうち、作業者が回動操作を行う機会が多く、負荷がかかって変形しやすい機体後側に設けていれば、補強効果は十分に発揮でき、回動苗枠36の変形や破損が防止される。これに加えて、前側に補強プレート39を設けないことにより、部品数や機体重量の軽減が図られる。 Further, as shown in FIGS. 2 and 8, the rear side of the seedling frame 31 on the other side of the machine body and the rear rotation support shaft 35b are connected by a reinforcing plate 39. The reinforcing plate 39 may be provided with one that connects the front part side of the seedling frame frame 31 on the left and right sides of the machine body and the rotation support shaft 35a on the front side. If the operator has many occasions to perform the rotating operation and is provided on the rear side of the machine body that is easily deformed due to a load, the reinforcing effect can be sufficiently exerted and the rotating seedling frame 36 is prevented from being deformed or damaged. In addition to this, by not providing the reinforcing plate 39 on the front side, the number of parts and the weight of the machine body can be reduced.

なお、前記載置台30は、苗箱38の長手方向を機体前後方向として載置する場合に3枚乗る程度の左右幅とし、前記回動苗枠36は、1枚の苗箱38が載る程度の左右幅とすると、機体から左右方向に突出する量を抑えつつ、苗箱38を補充する頻度を効果が実感できる程度で低減することが可能となる。 It should be noted that the above-mentioned mounting table 30 has a lateral width of about 3 sheets when the longitudinal direction of the seedling box 38 is set as the machine front-rear direction, and the rotating seedling frame 36 is such that one seedling box 38 is mounted. If the width is set to the right and left, it is possible to reduce the frequency of replenishing the seedling box 38 while suppressing the amount of protrusion from the machine body in the left and right direction.

また、前記載置台30は、第1載置枠33の機体左右一側端部を機体左右他側端部と同一形状とすると共に、前後の回動支軸35a,35bを装着する孔部(図示省略)を形成して構成し、回動苗枠36を機体左右一側に回動自在に装着可能にしてもよい。 In addition, in the mounting table 30, the left and right one-side ends of the first mounting frame 33 have the same shape as the left and right other-side ends of the body, and the hole portions for mounting the front and rear rotation support shafts 35a and 35b ( (Not shown) may be formed so that the rotating seedling frame 36 can be mounted rotatably on one side of the machine body.

なお、単純に回動苗枠36を装着すると前後が逆になり、第2回動枠36bの前後の突出量が逆になるので、機体左右他側に装着する状態においての裏面を、機体左右一側に装着するときの表面とする、或いは、図8に示すとおり、第2回動枠36bを第1回動枠36aに対して前後方向に移動(スライド)可能に装着するものとし、左右どちら側に装着しても同様に苗箱38を載置できる構成とする。 It should be noted that if the rotating seedling frame 36 is simply attached, the front and back will be reversed, and the amount of protrusion of the front and rear of the second rotating frame 36b will be opposite, so the back surface when attached to the other side of the aircraft It is assumed to be the surface when mounted on one side, or, as shown in FIG. 8, the second rotating frame 36b is mounted so as to be movable (sliding) in the front-rear direction with respect to the first rotating frame 36a. The seedling box 38 can be similarly placed on either side.

上記により、作業者の利き手や、作業を行う圃場の状態等の条件により、作業者が苗供給装置6の機体左右他側に立って苗の投入作業を行えないときに、機体左右一側に立って苗の投入作業を行うことができるので、様々な作業条件に対応できると共に、作業者が作業を行いやすい。 Due to the above, when the worker cannot stand on the other side of the body of the seedling supply device 6 to perform the seedling injection work due to the handedness of the worker or the condition of the field in which the work is performed, the left and right sides of the body can be operated. Since it is possible to stand up and perform seeding work, it is possible to handle various working conditions and it is easy for the worker to work.

前記載置台30及び回動苗枠36は、機体左右方向に複数の苗箱38を積載し、回動苗枠36上の苗箱38に収容されている苗が無くなると、空になった苗箱38を取り除き、載置台30に積載されている苗の入った苗箱38を回動苗枠36に移動させるのが、一般的な作業である。なお、空の苗箱38は、作業者が載置台30の空きスペースに積載すればよい。 The mounting table 30 and the rotating seedling frame 36 are loaded with a plurality of seedling boxes 38 in the lateral direction of the machine body, and when the seedlings stored in the seedling box 38 on the rotating seedling frame 36 are exhausted, the seedlings are emptied. It is a general work to remove the box 38 and move the seedling box 38 containing the seedlings loaded on the mounting table 30 to the rotating seedling frame 36. The empty seedling box 38 may be loaded in an empty space of the mounting table 30 by an operator.

このとき、回動苗枠36に近い苗箱38は、作業者があまり手を伸ばさなくて届くので、簡単に載置台30から回動苗枠36に移動させることができる。しかしながら、機体左右一側端部に載置される苗箱38は、作業者から離れた位置にあり、作業者は大きく手を伸ばさないと苗箱38を移動させにくいという問題がある。 At this time, since the operator can reach the rotating seedling box 38 near the rotating seedling frame 36, the operator can easily move the seedling box 38 from the mounting table 30 to the rotating seedling frame 36. However, the seedling box 38 placed on the left and right side ends of the machine body is at a position away from the operator, and there is a problem that the operator cannot easily move the seedling box 38 unless the operator extends his or her hand greatly.

この問題を解消すべく、8に示すとおり、前記載置台30を構成する第2載置枠34のうち、機体前後方向の線材部分に、苗箱搬送ローラ40…を回転可能に設ける。 In order to solve this problem, as shown in 8, a seedling box transport roller 40 is rotatably provided on a wire rod portion in the machine front-rear direction of the second mounting frame 34 constituting the mounting table 30.

これにより、載置台30の機体左右一側に設ける苗箱38は、隣接する苗箱38が離間すると、苗箱搬送ローラ40…の回転により機体左右他側に移動するので、作業者が手を無理に伸ばすことなく取れる位置に移動させることで、作業者の労力が軽減される。なお、苗箱38が移動しないときは、作業者は載置台30を揺さぶる等して、苗箱搬送ローラ40…の回転を促す。 As a result, the seedling boxes 38 provided on one side of the mounting table 30 on the left and right sides of the machine body move to the other side of the machine body by the rotation of the seedling box transportation rollers 40 when the adjacent seedling boxes 38 are separated from each other. By moving it to a position where it can be taken without stretching it, the labor of the operator is reduced. When the seedling box 38 does not move, the operator shakes the mounting table 30 or the like to prompt the rotation of the seedling box transport rollers 40.

このとき、苗箱38が機体左右一側端部に移動する可能性があるので、苗箱搬送ローラ40…には、機体左右他側に苗箱38を移動させる方向にのみ回転を許容するワンウェイクラッチ(図示省略)を設けるとよい。 At this time, the seedling box 38 may move to one end on the left and right sides of the machine body, so that the seedling box conveying rollers 40... One-way that allows rotation only in the direction of moving the seedling box 38 to the other side of the machine body. A clutch (not shown) may be provided.

また、空の苗箱38を積載したときに苗箱搬送ローラ40…が苗箱38を左右に移動させることを防止すべく、苗が収容されて重量が増加している苗箱38を載せると苗箱搬送ローラ40…が沈み込んで回転可能になる構成とすると、空の苗箱38が左右に移動し、載置台30から落下することが防止される。 Further, in order to prevent the seedling box transport rollers 40... from moving the seedling box 38 left and right when the empty seedling box 38 is loaded, the seedling box 38 in which seedlings are stored and whose weight is increasing is placed. If the seedling box carrying rollers 40 are set to be depressed and rotatable, the empty seedling box 38 is prevented from moving left and right and dropping from the mounting table 30.

前記載置台30と回動苗枠36の前端部は、前記左右の前輪4,4の後端部よりも機体前側で、且つ前輪4,4の車軸よりも機体後側に配置し、後端部は前記左右の後輪5,5の後端部よりも機体前側で、且つ後輪5,5の車軸よりも機体後側に配置する。これにより、前記載置台30と回動苗枠36は前輪4,4と後輪5,5の前後間に配置されることになる。 The front end portions of the mounting table 30 and the rotary seedling frame 36 are arranged on the front side of the vehicle body with respect to the rear end portions of the left and right front wheels 4 and 4 and on the rear side of the vehicle body with respect to the axles of the front wheels 4 and 4, and the rear ends thereof. The parts are arranged on the front side of the machine body with respect to the rear end portions of the left and right rear wheels 5, 5 and on the rear side of the machine body with respect to the axles of the rear wheels 5, 5. As a result, the mounting table 30 and the rotating seedling frame 36 are arranged in front of and behind the front wheels 4, 4 and the rear wheels 5, 5.

上記構成により、載置台30及び回動苗枠36を機体の前後バランスが変動しにくい位置に配置することができるので、植付作業により苗が減少すると重量が軽くなる苗箱38を積載していても機体が前上がりや後上がりになりにくく、植付ホッパ72が前傾姿勢、または後傾姿勢で苗を植え付けることが防止され、苗の根部側が均等に土に覆われて気温の影響を受けにくくなると共に、茎部や葉部が土に埋もれず、光合成機能が損なわれない。 With the above configuration, the placing table 30 and the rotating seedling frame 36 can be arranged at a position where the front-rear balance of the machine body is unlikely to change, so that the seedling box 38 that is lighter in weight when the seedlings are reduced by the planting work is loaded. Even if the aircraft does not rise or rise backwards, the planting hopper 72 is prevented from planting seedlings in a forward tilting posture or a backward leaning posture, and the root side of the seedlings is evenly covered with soil to prevent the influence of temperature. It is hard to receive, and the stems and leaves are not buried in the soil, and the photosynthetic function is not impaired.

また、前記載置台30及び回動苗枠36は、左右の支持フレーム31,31の後下がり傾斜姿勢となる部分に装着することで、同じく後下がり傾斜姿勢となるが、最下位置となる後端部は、苗供給装置6の上端面と同じ高さか、あるいは上端面よりもやや上方に位置する構成とする。 Further, by mounting the mounting table 30 and the rotating seedling frame 36 on the portions of the left and right support frames 31, 31 which are in the backward descending tilted posture, they are also in the rearward descending inclined posture, but at the bottom position. The end is configured to be at the same height as the upper end surface of the seedling feeding device 6 or slightly above the upper end surface.

これにより、作業者が苗箱38から苗を取って移動させる際、苗供給装置6よりも上方に腕を上げる動作が不要になるので、腕が疲れにくく作業者の労力が軽減される。 As a result, when the operator takes the seedlings from the seedling box 38 and moves the seedlings, it is not necessary to raise the arm above the seedling feeding device 6, so that the arm is less tired and the labor of the operator is reduced.

また、苗箱38から苗供給装置6への移動時間が僅かでも短縮されるので、苗の投入タイミングが遅れ、植付ホッパ72に苗が供給されず、苗の植え付けが行われない、所謂欠株の発生が防止され、手作業による苗の植付作業が不要になる。 Further, since the moving time from the seedling box 38 to the seedling feeding device 6 is shortened even a little, the timing of feeding the seedlings is delayed, the seedlings are not supplied to the planting hopper 72, and the seedlings are not planted. Strains are prevented from occurring and manual planting work of seedlings is unnecessary.

また、前記載置台30の左右一側端部、即ち第1載置枠33の左右一側端部は、前記ハンドル9の機体左右一側よりも機体外側に突出させる。 The left and right side ends of the mounting table 30, that is, the left and right side ends of the first mounting frame 33 are projected to the outside of the machine body rather than the one side of the machine body of the handle 9.

これにより、載置台30の左右一側端部が機体左右一側のガード体になるので、作業者がハンドル9を把持して移動している際、機体の側方に壁や柱等の障害物があると、載置台30の突出部が接触するので、作業者が障害物に接触することが防止される。 As a result, the left and right side end portions of the mounting table 30 serve as a guard body on the left and right sides of the machine body. Therefore, when an operator grips the handle 9 and moves, obstacles such as walls and pillars are laterally present on the machine body. When there is an object, the protruding portion of the mounting table 30 comes into contact, so that the worker is prevented from coming into contact with the obstacle.

なお、機体左右他側のガード体は、展開状態では回動苗枠36であり、回動苗枠36を収納しているときは、載置台30の左右他側端部、即ち第1載置枠33の左右他側端部である。 In addition, the guard body on the other side of the machine body is the rotating seedling frame 36 in the unfolded state, and when the rotating seedling frame 36 is stored, the left and right other end portions of the mounting table 30, that is, the first mounting The left and right other side ends of the frame 33.

そして、前記苗供給装置6は、植付装置7の上方位置で苗を受けて周回軌道64上を移送する8個の供給カップ62…を備え、回転駆動機構66の回転動力によって所定速度で回転作動される。なお、この回転作動は植付装置7の昇降動作と対応させており、すなわち、苗供給装置6から苗が落下するタイミングを植付装置7が最も上昇した位置にある時に同期させている。 The seedling supply device 6 includes eight supply cups 62... Which receive the seedlings above the planting device 7 and transfer them on the circular orbit 64, and rotate at a predetermined speed by the rotation power of the rotation drive mechanism 66. Is activated. This rotation operation corresponds to the raising/lowering operation of the planting device 7, that is, the timing of dropping the seedlings from the seedling supplying device 6 is synchronized when the planting device 7 is at the most raised position.

図3には、苗供給装置6の各構成部品を説明するための分解斜視図を示す。 FIG. 3 shows an exploded perspective view for explaining each component of the seedling feeding device 6.

苗供給装置6は、植付装置7の上方に設けられた、上端と下端に開口部62aを有する供給カップ62を8つ貫通させてループ状に配置した回転可能な回転テーブル61と、その下側に配置されて且つ移植機1の機体側に固定配置された支持板26と、回転テーブル61を反時計回りに回転させるための回転駆動機構66等を備えている。 The seedling supply device 6 includes a rotatable rotary table 61 provided above the planting device 7 and arranged in a loop shape by penetrating eight supply cups 62 having openings 62a at the upper and lower ends, and below the rotatable rotary table 61. And a rotation drive mechanism 66 for rotating the rotary table 61 counterclockwise, and the like.

回転テーブル61は、外周縁部61aが下方に曲げられた盆状部材であって、その円形平面部(主面部)61bの外周寄りに等間隔に開けられた8つの貫通孔に、両端が開放された円筒状の供給カップ62がそれぞれ貫通して設けられている。また、回転テーブル61の中央部には、回転駆動機構66からの回転力により回転テーブル61を反時計回りに回転するための回転軸66fが固定配置されている。 The rotary table 61 is a tray-shaped member whose outer peripheral edge portion 61a is bent downward, and its both ends are open to eight through-holes formed at equal intervals near the outer periphery of the circular flat surface portion (main surface portion) 61b. The cylindrical supply cups 62 are provided so as to penetrate therethrough. Further, a rotary shaft 66f for rotating the rotary table 61 counterclockwise by a rotational force from the rotary drive mechanism 66 is fixedly arranged at the center of the rotary table 61.

支持板26は、植付装置7の受け継ぎ位置Gに開口部27が設けられた円盤状の板部材であって、供給カップ62の直ぐ下側で、回転テーブル61の円形平面部(主面部)61bに平行であって、後述する支柱93に溶接によって固定されている。支持板26の更に下側には、回転駆動機構66が設けられている。 The support plate 26 is a disk-shaped plate member having an opening 27 provided at the inheritance position G of the planting device 7, and immediately below the supply cup 62, a circular flat surface portion (main surface portion) of the rotary table 61. It is parallel to 61b and is fixed to a post 93 described later by welding. A rotary drive mechanism 66 is provided below the support plate 26.

この支持板26は、出っ張り部29を除き、回転テーブル61の直径より小さく、且つ、リング状に配置された8個の供給カップ62の下端の開口の投影領域を包括できる直径の円盤状の板部材であり、その板部材の一部には、供給カップ62の下端開口の直径より大きい円形状の開口部27が、植付ホッパ部72への受け継ぎ位置G、すなわち植付ホッパ部72が上死点に位置する時の植付ホッパ部72のロート状上部筒部71の上方に対応する位置に1つ形成されている。 The support plate 26 is a disc-shaped plate having a diameter smaller than the diameter of the rotary table 61 except for the protruding portion 29 and capable of covering the projection area of the lower opening of the eight supply cups 62 arranged in a ring shape. A circular opening 27 having a diameter larger than the diameter of the lower end opening of the supply cup 62 is provided on a part of the plate member, and a position G inherited to the planting hopper part 72, that is, the planting hopper part 72 is located above. One is formed at a position corresponding to above the funnel-shaped upper cylinder part 71 of the planting hopper part 72 when it is located at the dead point.

また、支持板26は、供給カップ62の下端の縁部から所定の距離を隔てて、回転テーブル61の主面に平行に配置されており、供給カップ62に補給された苗が、開口部27を除き、支持板26と供給カップ62の下端の縁部との隙間から落下することが無く、しかも、回転移動する供給カップ62が、動作中に振動などしても、支持板26にぶつかることがない程度の間隔が確保されている。 Further, the support plate 26 is arranged in parallel to the main surface of the rotary table 61 at a predetermined distance from the edge of the lower end of the supply cup 62, and the seedlings supplied to the supply cup 62 are opened by the opening 27. Except for the above, there is no drop from the gap between the support plate 26 and the edge of the lower end of the supply cup 62, and the rotating supply cup 62 does not collide with the support plate 26 even if it vibrates during operation. There is no gap between them.

支持板26には、その上面に溜まったゴミなどを効果的に排出し、苗は落下しない程度の大きさのスリット状の長孔部35が、半径方向に沿って形成されている。 On the support plate 26, slit-like long holes 35 are formed along the radial direction having a size such that dust and the like collected on the upper surface thereof are effectively discharged and seedlings do not drop.

一方、回転テーブル61の裏面には、支持板26に形成された長孔部35からゴミを落とすための長方形状の硬質ゴム製のスクレーパ36が固定配置されている。 On the other hand, on the back surface of the rotary table 61, a rectangular hard rubber scraper 36 is fixedly arranged for removing dust from the long holes 35 formed in the support plate 26.

また、支持板26は、移植機1の機体から後方に向けて配置されている支柱93により支持されると共に、その支持部において溶接固定されている。なお、後述する軸受け部材66gの外周側面は、支柱93の後方端93aに固定されている(図3参照)。 In addition, the support plate 26 is supported by columns 93 arranged rearward from the body of the transplanter 1, and is welded and fixed at the support portion. The outer peripheral side surface of the bearing member 66g described later is fixed to the rear end 93a of the support column 93 (see FIG. 3).

なお、上記構成によれば、供給カップ62の下端は開放されており、すなわち蓋が無く、しかも支持板26の裏面に支柱93が直接固定されているので、供給カップ62の下端の開口位置と、植付ホッパ部72の上死点との距離がより短くできる。なお、供給カップ62の底全面ではなく、底面の一部に開口部62aを設けても良い。 According to the above configuration, the lower end of the supply cup 62 is open, that is, since there is no lid and the column 93 is directly fixed to the back surface of the support plate 26, the opening position of the lower end of the supply cup 62 is The distance from the top dead center of the planted hopper 72 can be shortened. The opening 62a may be provided on a part of the bottom surface of the supply cup 62 instead of the entire bottom surface.

そして、回転駆動機構66は回転テーブル駆動ケース25bに一端が回転可能に接続され、回転方向変換ユニット66bの入力側に他端が回転可能に接続された回転力伝達部材66cと、回転方向変換ユニット66bの入力側の回転軸に対して直交配置された出力側の回転軸66dに固定された第1歯車66e1と、第1歯車66e1と噛み合って配置された第2歯車66e2とを備えている。第2歯車66e2は反時計方向に滑らかに回転する。 The rotary drive mechanism 66 has one end rotatably connected to the rotary table drive case 25b, and the other end rotatably connected to the input side of the rotation direction conversion unit 66b, and the rotation direction transmission unit 66c. The first gear 66e1 is fixed to the output-side rotary shaft 66d that is disposed orthogonal to the input-side rotary shaft of 66b, and the second gear 66e2 that is arranged to mesh with the first gear 66e1. The second gear 66e2 smoothly rotates counterclockwise.

また、回転方向変換ユニット66bの上面には、回転方向変換ユニット固定用アングル67が締結部品67aによって固定されている。更に、回転方向変換ユニット66bは、回転方向変換ユニット固定用アングル67を介して、支持板26の裏面に固定されているユニット固定用アングル68に締結部品67bによって固定されている。 A rotation direction conversion unit fixing angle 67 is fixed to the upper surface of the rotation direction conversion unit 66b by a fastening component 67a. Further, the rotation direction changing unit 66b is fixed to the unit fixing angle 68 fixed to the back surface of the support plate 26 by the fastening component 67b via the rotation direction changing unit fixing angle 67.

また、軸受け部材66gは、第2歯車66e2の回転軸66fを回転可能に支持する軸受け部材であり、上述した通り、その外周側面の下端側において、支柱93の後方端93aと固定されている。一方、軸受け部材66gの上端側は、支持板26の中心部に設けられた貫通孔28を貫通しており、軸受け部材66gから上方に飛び出している回転軸66fが回転テーブル61の中心部に固定されている。これにより、回転テーブル61は、回転軸66fを介して、軸受け部材66gにより回転可能に支持されている。 The bearing member 66g is a bearing member that rotatably supports the rotating shaft 66f of the second gear 66e2, and is fixed to the rear end 93a of the support column 93 on the lower end side of the outer peripheral side surface thereof, as described above. On the other hand, the upper end side of the bearing member 66g penetrates the through hole 28 provided in the central portion of the support plate 26, and the rotary shaft 66f protruding upward from the bearing member 66g is fixed to the central portion of the rotary table 61. Has been done. As a result, the rotary table 61 is rotatably supported by the bearing member 66g via the rotary shaft 66f.

苗を植え付ける圃場の土中には基本的に虫や菌類等の生物が生息している。また、大気中や供給する水の中にも、菌類等の生物が生息している。こうした生物の中には、植え付けられた苗の根や葉を食べたり、病気に罹らせたりする等、苗の生育に悪影響を与えるものが存在する。 Organisms such as insects and fungi basically live in the soil of the field where seedlings are planted. In addition, organisms such as fungi inhabit the atmosphere and the water supplied. Among these organisms, there are some that adversely affect the growth of seedlings, such as eating roots and leaves of planted seedlings and getting diseases.

この問題の発生を防止するには、殺虫、殺菌作用を持つ薬剤を苗の周囲に供給し、駆除や防除を行う必要がある。しかしながら、苗の植付後に薬剤を供給するとなると、植え付けられた苗の位置に合わせて薬剤を供給する必要があり、作業に時間を要する問題がある。 In order to prevent the occurrence of this problem, it is necessary to supply a drug having an insecticidal or bactericidal action to the periphery of the seedlings for extermination or control. However, if the drug is supplied after planting the seedlings, it is necessary to supply the drug in accordance with the position of the planted seedlings, and there is a problem that the work takes time.

また、薬剤の中には、虫や菌類に直接作用するのではなく、苗に成分を吸収させ、苗に生物が近寄らなくするものや、苗を食べた生物を駆除するものもある。こうした薬剤は、作物の成長に従い分解、または排出されていくが、供給時期が遅いと出荷する段階でも作物中に成分が残ってしまい、残留量によっては商品として出荷できなくなることがある。 In addition, some medicines do not act directly on insects and fungi, but absorb the components into the seedlings to prevent the organisms from approaching the seedlings, and some to exterminate the organisms that eat the seedlings. These drugs are decomposed or discharged according to the growth of crops, but if the supply period is late, the components remain in the crops even at the shipping stage, and depending on the residual amount, they may not be shipped as products.

なお、こうした成分は、対象の苗を食べる虫や、苗を病気にする菌類に対して作用する物質で構成されており、高濃度に残留していなければ基本的に人畜には無害な物質である。しかしながら、出荷可能な商品が減少することや、風評被害を受けることを防止する観点からすれば、成分の残留は好ましくない。 Note that these components are composed of substances that act on insects that eat the target seedlings and fungi that make the seedlings ill, and are basically harmless to humans and animals unless they remain in high concentrations. is there. However, from the viewpoint of reducing the number of products that can be shipped and preventing damage to reputation, residual components are not preferable.

上記の問題を防止するには、移植機による圃場への苗の移植時に、苗の植付位置に薬剤を供給することが望ましい。これを実現すべく、野菜苗の移植機に薬剤供給装置を設けるものが存在する。この移植機では、薬剤供給装置から供給される粒状の薬剤を案内する供給ホースの後端部(出口側)を、植付装置の後方に臨ませ、植え付けられた苗、及びその周囲に薬剤が供給される構成としている。 In order to prevent the above problems, it is desirable to supply the drug to the planting position of the seedlings when the seedlings are transplanted to the field by the transplanter. In order to realize this, there is a plant provided with a drug supply device in a plant for transplanting vegetable seedlings. In this transplanter, the rear end (exit side) of the supply hose that guides the granular drug supplied from the drug supply device is exposed to the rear of the planting device so that the seedlings planted in and around the seedling are not covered with the drug. It is configured to be supplied.

しかしながら、植付装置より機体前側に薬剤供給装置を設ける移植機では、薬剤散布装置から植付装置までの間隔が広くなりやすく、その分供給ホースが長くなる。従って、薬剤供給装置のホッパに貯留された薬剤が供給ホースから放出される際、走行速度等の条件によっては苗から離れた位置に薬剤が供給され、殺虫、殺菌作用が十分に発揮されないおそれがある。 However, in the transplanter in which the drug supply device is provided on the front side of the machine with respect to the planting device, the distance from the drug spraying device to the planting device tends to be wide, and the supply hose becomes longer accordingly. Therefore, when the medicine stored in the hopper of the medicine supply device is released from the supply hose, the medicine may be supplied to a position away from the seedling depending on the conditions such as the traveling speed, and the insecticidal and bactericidal effects may not be sufficiently exerted. is there.

また、薬剤供給装置から植付装置までの前後間隔が広いことにより、供給ホースは比較的緩やかな傾斜角度で苗の植付位置に向かうので、さらに薬剤の供給タイミングが遅れやすくなると共に、供給ホースに曲がりが生じていると、薬剤が詰まって供給されなくなるおそれがある。 In addition, since the front-rear distance from the drug supply device to the planting device is wide, the supply hose moves toward the seedling planting position at a relatively gentle inclination angle, which makes it easier to delay the drug supply timing and also to supply the hose. If there is a bend, the medicine may become clogged and the medicine may not be supplied.

苗供給テーブルの前方に薬剤供給装置を配置し、この問題を解消する構成もあるが、薬剤供給装置の前方にはエンジンやミッションケースがあり、後方には苗供給テーブルがあり、左右には走行伝動ケースや走行輪があるので、作業者が薬剤供給装置に近付きにくく、薬剤の補充や排出作業が行いにくい問題がある。 There is also a configuration that solves this problem by disposing a drug supply device in front of the seedling supply table, but there is an engine and a mission case in front of the drug supply device, there is a seedling supply table in the back, and there is a running to the left and right. Since the transmission case and the running wheels are provided, there is a problem that it is difficult for an operator to approach the medicine supply device and it is difficult to replenish or discharge the medicine.

一方、薬剤供給装置よりも機体後側に薬剤供給装置を設けると、植付装置の苗の植付位置に、垂直に近い傾斜角度で供給ホースを配置できる。また、機体の後方には薬剤供給装置への接近を妨げる部材は少なく、薬剤の供給や排出作業も行いやすい。 On the other hand, if the medicine supply device is provided on the rear side of the machine body with respect to the medicine supply device, the supply hose can be arranged at a seedling planting position of the planting device at an inclination angle close to vertical. Further, there are few members behind the machine body that hinder access to the medicine supply device, and it is easy to perform medicine supply and discharge operations.

しかしながら、苗の植付時の機体の移動により、苗の植付位置と供給ホースから肥料が供給される位置に前後間隔が生じやすく、苗から離れた位置に薬剤が供給され、殺虫、殺菌作用が十分に発揮されないおそれがある。 However, due to the movement of the aircraft during planting of seedlings, a front-to-back space is likely to occur between the planting position of the seedlings and the position where fertilizer is supplied from the supply hose, and the drug is supplied to the position away from the seedlings, and insecticidal and bactericidal action May not be fully exerted.

また、薬剤を充填することで重量が増す薬剤供給装置を機体の後方に配置することにより、機体後方に重量バランスが偏りやすくなり、機体前側が浮き上がりがちになり、苗の植付深さが設定どおりにならなくなる問題がある。 In addition, by placing a drug supply device that increases the weight by filling the medicine behind the machine, the weight balance is likely to be biased toward the rear of the machine, the front side of the machine tends to float, and the planting depth of seedlings is set. There is a problem that it will not go as expected.

この問題を解消すべく、図1、図2で示すとおり、前記苗供給装置6を支持する支柱93のうち、平面視で前記植付装置7の機体左右一側の側方で、且つ平行となる位置に、機体左右他側の外側に向かう取付アーム50を設け、該取付フレーム50に平面視でコの字形状の支持フレーム51を、開口部が機体左右一側(機体内側)を向けて装着する。該支持フレーム51には、前後に取付穴が形成されており、この取付穴にボルト等の固定部材を差し込み、粒状体である薬剤を供給する薬剤供給装置52の繰出装置53を固定する。 In order to solve this problem, as shown in FIG. 1 and FIG. 2, among the columns 93 that support the seedling feeding device 6, in the plan view, on the left and right sides of the body of the planting device 7, and parallel to each other. A mounting arm 50 that faces the outside of the other side of the machine body is provided at a position, and a support frame 51 having a U-shape in a plan view is provided on the mounting frame 50 with the opening facing one side of the machine body (the inside of the machine body). Mounting. Mounting holes are formed in the front and rear of the support frame 51, and fixing members such as bolts are inserted into the mounting holes to fix the feeding device 53 of the drug supply device 52 that supplies the drug as a granular material.

上記構成により、苗供給装置6の機体左右一側のスペースを利用して薬剤供給装置52を配置することができるので、薬剤供給装置52に薬剤を供給する、または薬剤供給装置52から薬剤を排出する等の作業を行いやすく、作業能率が向上する。 With the above-described configuration, the medicine supply device 52 can be arranged using the space on one side of the machine body of the seedling supply device 6, so that the medicine is supplied to the medicine supply device 52 or discharged from the medicine supply device 52. It is easy to perform work such as doing, and work efficiency is improved.

また、薬剤供給装置52が植付装置7の機体左右一側の側方に平行な姿勢で配置されることにより、植付伝動ケース24やリンク機構75の重量に対するカウンターウェイトになるので、機体の左右バランスが向上する。 In addition, since the medicine supply device 52 is arranged in a posture parallel to one lateral side of the planting device 7 on the left and right sides of the machine body, it becomes a counterweight against the weight of the planting transmission case 24 and the link mechanism 75. The left-right balance is improved.

なお、図2において、移植機は左右非対称に見え、左右バランスの向上は見込めないように思われるが、薬剤供給装置52は主フレーム15の左右一側に、植付装置7は主フレーム15の左右他側に設けられるので、左右方向の重量バランスが安定することになる。 It should be noted that in FIG. 2, the transplanter looks asymmetrical to the left and right, and it seems that improvement in left-right balance cannot be expected, but the drug supply device 52 is located on one side of the main frame 15, and the planting device 7 is installed on the main frame 15. Since it is provided on the left and right sides, the weight balance in the left and right directions is stable.

該繰出装置53は、図4に示すとおり、機体前後方向の繰出回転軸54,54の回転により回転する、外周縁部に薬剤が所定量入り込む繰出溝55aを所定間隔ごとに複数形成した左右の繰出ロール55,55を内装する。該左右の繰出ロール55,55の機体前側、または後側の外周縁部には、互いに噛み合う伝達歯部55bが形成され、左右どちらか一方の繰出ロール55の回転に伴い、他方の繰出ロール55を反対方向に回転させる構成とする。なお、左右の繰出ロール55,55の回転方向は、機体左右一側(左側)の繰出ロール55が反時計回り方向に回転し、機体左右他側(右側)の繰出ロール55が時計回り方向に回転するものとする。 As shown in FIG. 4, the feeding device 53 is provided with a plurality of feeding grooves 55a, which are rotated by the rotation of the feeding rotation shafts 54, 54 in the longitudinal direction of the machine body, into the outer peripheral edge portion of which a prescribed amount of the medicine enters at predetermined intervals. The feeding rolls 55, 55 are incorporated. Transmission tooth portions 55b that mesh with each other are formed on the outer peripheral edge portions of the left and right feeding rolls 55, 55 on the front side or the rear side of the machine body, and the rotation of one of the left and right feeding rolls 55 causes the other feeding roll 55 to rotate. Is rotated in the opposite direction. Regarding the rotation direction of the left and right feeding rolls 55, 55, the feeding roll 55 on the left and right side of the machine body (left side) rotates counterclockwise, and the feeding roll 55 on the other side of the machine body (right side) rotates in the clockwise direction. It shall rotate.

上記構成により、左右の繰出ロール55,55の両方に駆動力を伝動する必要がなく、伝動経路を簡潔な構成とすることができるので、部品点数が削減され、機体の軽量化が図られると共に、コストの増加が抑えられる。 With the above configuration, it is not necessary to transmit the driving force to both the left and right feeding rolls 55, 55, and the transmission path can be made simple, so that the number of parts is reduced and the weight of the machine body is reduced. The cost increase can be suppressed.

また、伝達歯部55b,55bの噛み合いにより、どちらか一方の繰出ロール55の回転速度に他方の繰出ロール55の回転速度を同調させることができるので、薬剤の供給量にバラつきが生じることが防止される。これにより、薬剤不足による病害や食害、あるいは薬剤過多による苗や土壌の汚染が防止される。 Further, since the rotation speed of either one of the feeding rolls 55 can be synchronized with the rotation speed of one of the feeding rolls 55 by the meshing of the transmission tooth portions 55b, 55b, it is possible to prevent the supply amount of the medicine from varying. To be done. This prevents disease and food damage due to lack of chemicals, and contamination of seedlings and soil due to excessive chemicals.

そして、図4に示すとおり、上記の繰出装置53の上部には、粒状体である薬剤を貯留する貯留ホッパ56を配置する。該貯留ホッパ56は、上部に開閉自在な蓋56aが設けられ、下部には繰出装置53に薬剤を流下させる流下空間部(図示省略)を有するものである。 Then, as shown in FIG. 4, a storage hopper 56 for storing the medicines in the form of particles is arranged above the feeding device 53. The storage hopper 56 is provided with an openable/closable lid 56a in the upper part, and has a flow-down space (not shown) in the lower part for allowing the medicine to flow down to the feeding device 53.

なお、貯留ホッパ56は、貯留する薬剤の残量を作業者が目視で把握可能とすべく、透明または半透明とするとよい。また、貯留する薬剤の成分による腐食を防止すべく、耐薬品性のある素材で構成するか、またはコーティングを施すとよい。 The storage hopper 56 may be transparent or translucent so that the operator can visually recognize the remaining amount of the stored medicine. Further, in order to prevent corrosion due to the components of the stored chemicals, it is preferable to use a material having chemical resistance or apply a coating.

また、貯留ホッパ56には、薬剤だけでなく、植付後の苗が生育に使用する粒状の肥料を投入してもよい。 In addition to the chemicals, the storage hopper 56 may be charged with granular fertilizer used for growing seedlings after planting.

さらに、前記繰出装置53の下部には、左右の繰出ロール55,55から放出される薬剤を植付装置7により植え付けられた苗、及び苗の植付位置の周囲に供給する案内ホース57を、圃場面に向けて装着する。該案内ホース57の終端部、即ち薬剤の出口は、平面視において植付装置7の機体左右一側の側方、即ち真横に平行に配置される薬剤供給装置52とは異なり、植付装置7の後方の近傍とする。苗の植付作業時には車体10が前進しているので、案内ホース57から排出される薬剤は苗の上方から苗、及び植付位置の周辺に散布されることになる。 Furthermore, in the lower part of the feeding device 53, a seedling planted by the planting device 7 and the guide hose 57 for supplying the medicine discharged from the left and right feeding rolls 55, 55 to the periphery of the planting position of the seedling, Attach it to the field scene. The terminal end of the guide hose 57, that is, the medicine outlet, is different from the medicine supply device 52 which is arranged in parallel to the right and left sides of the machine body 7 in plan view, that is, right beside the medicine supply device 52. Near the back of. Since the vehicle body 10 is moving forward during the seedling planting operation, the medicine discharged from the guide hose 57 is sprayed from above the seedling to the seedling and the periphery of the planting position.

なお、薬剤の種類によって、苗に接触させるべきものと、なるべく接触させず土壌に供給すべきものがあるので、案内ホース57の終端部の位置を変更可能に構成してもよい。 Depending on the kind of the medicine, there are those that should be brought into contact with the seedlings and those that should be supplied to the soil without being brought into contact with them as much as possible. Therefore, the position of the terminal end portion of the guide hose 57 may be changeable.

前記案内ホース57は、一般的に塩化ビニル等の軟性素材で構成するものであり、前記繰出装置53から垂直に近い姿勢で配置するだけでは、車体10の前進や各部の駆動による振動の影響で揺らぐと、終端部の位置が前後や左右にランダムに移動することになり、薬剤の供給位置が不安定になる。従って、車体10の左右中央位置、即ち前記左右の前輪4,4及び後輪5,5の左右中央位置から機体左右一側寄りに偏倚させて配置する前記主フレーム15の機体左右他側に、案内ホース57の終端部側、即ち圃場面に向かって略垂直な姿勢となる部分の少なくとも一部を保持するホース支持部材58を設け、案内ホース57の揺らぎを防止する構成とする。 The guide hose 57 is generally made of a flexible material such as vinyl chloride. If the guide hose 57 is arranged in a posture close to the vertical from the feeding device 53, the guide hose 57 may be affected by the vibration of the forward movement of the vehicle body 10 and the drive of each part. If it fluctuates, the position of the end portion will move randomly back and forth and left and right, making the drug supply position unstable. Therefore, on the left and right sides of the main frame 15 which are arranged so as to be offset from the left and right center positions of the vehicle body 10, that is, the left and right center positions of the left and right front wheels 4, 4 and the rear wheels 5, 5, to the left and right sides of the main frame 15, A hose support member 58 that holds at least a part of the end portion of the guide hose 57, that is, a portion that is in a substantially vertical posture toward the field scene is provided to prevent the guide hose 57 from fluctuating.

なお、該ホース支持部材58は、案内ホース57の径よりも僅かに大径のボスや、ワイヤやプラスチックで構成するバンドとし、案内ホース57の内部に付着した薬剤の除去作業時等に、簡単に取り外しが可能な構成とするとよい。 The hose support member 58 is a boss having a diameter slightly larger than the diameter of the guide hose 57, or a band made of wire or plastic, and is easy to remove when the chemicals adhering to the inside of the guide hose 57 are removed. It is advisable to have a removable structure.

また、上記のとおり、薬剤の排出方向を調整可能とすべく、ホース支持部材58の角度を変更したり、取付位置を主フレーム15に沿って変更したりできる構成とすることが望ましい。 Further, as described above, it is desirable that the angle of the hose support member 58 can be changed and the mounting position can be changed along the main frame 15 so that the discharge direction of the medicine can be adjusted.

前記薬剤供給装置52が薬剤を供給するタイミングは、苗供給装置6が植付装置7へ苗を投入するタイミングに合わせることが望ましい。一方、薬剤供給装置52は苗供給装置6の機体左右一側の側方に配置されることにより、ミッションケース3から駆動力を伝動する伝動経路を新たに構成すると、伝動方向を変更する部材を多く用いる必要があり、伝動経路の複雑化や部品点数の増加を招くので、新たに伝動経路を追加することは望ましくない。 It is desirable that the timing at which the chemical supply device 52 supplies the chemicals be matched with the timing at which the seedling supply device 6 inputs the seedlings to the planting device 7. On the other hand, when the medicine supply device 52 is arranged on one side of the seedling supply device 6 on the left and right sides of the machine body, a transmission path for transmitting the driving force from the mission case 3 is newly configured, and a member for changing the transmission direction is provided. Since it is necessary to use a large number of transmission lines, which complicates the transmission path and increases the number of parts, it is not desirable to add a new transmission path.

したがって、図1、図2及び図5に示すとおり、前記ミッションケース3から苗供給装置6へ駆動力を伝動する前記回転力伝達部材66cに、機体左右一側に向かう分岐伝動ケース80を装着する。該分岐伝動ケース80には、回転力伝達部材66cの回転により回転する駆動プーリ81と、従動プーリ82と、該駆動プーリ81及び従動プーリ82に亘って無端状に巻回される伝動ベルト83が内装される。 Therefore, as shown in FIG. 1, FIG. 2 and FIG. 5, the branch transmission case 80 heading to one side of the machine body is attached to the rotational force transmission member 66c that transmits the driving force from the mission case 3 to the seedling feeding device 6. .. The branch transmission case 80 includes a drive pulley 81 that is rotated by the rotation of the rotational force transmission member 66c, a driven pulley 82, and a transmission belt 83 that is endlessly wound around the drive pulley 81 and the driven pulley 82. It is decorated.

そして、該従動プーリ82には、前記薬剤供給装置52に駆動力を伝動する繰出伝動軸59の一端を差し込み、該繰出伝動軸59の他端を、前記左右の繰出ロール55,55のどちらか一方に装着する。 Then, one end of a delivery transmission shaft 59 that transmits a driving force to the medicine supply device 52 is inserted into the driven pulley 82, and the other end of the delivery transmission shaft 59 is inserted into one of the left and right delivery rolls 55, 55. Attach to one side.

なお、図4に示すとおり、前記左右の繰出回転軸54,54は、中空で内部にスプライン加工が施されるものとし、繰出伝動軸59の他端の外周に施されるスプライン加工された部分を差し込む構成とする。また、繰出伝動軸59はユニバーサルジョイントとすると、取り付ける繰出ロール55,55を選択する際、どちらでも容易に装着できる。 As shown in FIG. 4, the left and right payout rotary shafts 54, 54 are hollow and have splined interiors, and the splined parts applied to the outer periphery of the other end of the payout transmission shaft 59. It is configured to insert. Further, if the feeding transmission shaft 59 is a universal joint, either one can be easily mounted when selecting the feeding rolls 55, 55 to be mounted.

上記構成により、苗供給装置6への伝動機構を利用して薬剤供給装置52に駆動力を伝動することができるので、苗供給装置6が植付装置7に苗を供給するタイミングで薬剤の供給を行うことができる。これにより、苗や植付位置の周囲の土壌に薬剤が確実に供給されるので、害虫による食害や菌等による病害の発生が防止され、苗の生育不良や立ち枯れが防止される。 With the above-described configuration, since the driving force can be transmitted to the medicine supplying device 52 by using the transmission mechanism to the seedling supplying device 6, the medicine supplying is performed at the timing when the seedling supplying device 6 supplies the seedlings to the planting device 7. It can be performed. As a result, the chemical is reliably supplied to the seedlings and the soil around the planting position, so that the feeding damage caused by the harmful insects and the disease caused by the fungi can be prevented, and the poor growth of the seedlings and the dead seedlings can be prevented.

また、部品点数の増加を抑えることができるので、構成の簡潔化や機体の軽量化が図られると共に、コストの増加が抑えられる。 Further, since it is possible to suppress an increase in the number of parts, it is possible to simplify the configuration, reduce the weight of the machine body, and suppress an increase in cost.

前記薬剤供給装置52は、平面視においては機体左右一側の後輪5の後部側の上方にオーバーラップさせて配置し、側面視においては苗供給装置6の前部側とオーバーラップさせて配置する。 The drug supply device 52 is arranged so as to overlap above the rear part side of the rear wheel 5 on one side of the machine body in a plan view, and to be overlapped with the front part side of the seedling supply device 6 in a side view. To do.

これにより、薬剤供給装置52が機体の高位置に配置され、案内ホース57を垂直に近い角度の傾斜姿勢で配置できるので、薬剤の移動速度の低下が防止され、薬剤を必要な位置に適切に供給することが可能になる。 As a result, the medicine supply device 52 is arranged at a high position of the machine body, and the guide hose 57 can be arranged in an inclined posture at an angle close to the vertical, so that the movement speed of the medicine is prevented from decreasing and the medicine is properly placed at a necessary position. Can be supplied.

また、貯留ホッパ56が機体の高位置に配置されるので、作業者が薬剤の供給作業を行う際に腰をかがめる必要がなく、作業に要する労力が軽減される。 Further, since the storage hopper 56 is arranged at a high position of the machine body, it is not necessary for the worker to bend down when performing the medicine supply work, and the labor required for the work is reduced.

なお、図1に示すとおり、案内ホース57は、繰出装置53の装着部から略垂直姿勢で下方に向かわせ、苗供給装置6及び回転駆動機構66を支持する供給部フレーム49の側方付近で機体後方に向けて後下がり傾斜姿勢とすべく屈曲させると共に、主フレーム15の側方で機体左右一側から機体左右他側に向けて屈曲させ、再び垂直姿勢になった部分をホース支持部材58で支持する構成とする。 In addition, as shown in FIG. 1, the guide hose 57 is directed downward from the mounting portion of the feeding device 53 in a substantially vertical posture, and near the side of the feeding portion frame 49 that supports the seedling feeding device 6 and the rotation driving mechanism 66. The hose support member 58 is bent toward the rear of the machine body so as to be inclined downwardly, and is bent laterally of the main frame 15 from one side of the machine body to the other side of the machine body to be in a vertical posture again. Will be supported by.

前記薬剤供給装置52を苗供給装置6の機体左右一側の側方に配置することにより、苗供給装置6の機体左右他側の側方及び斜め後方は空間部となる。この空間部を、載置台30に積載された苗箱38のうち、機体左右他側に設置された苗箱38から苗を取り、苗供給装置6に投入する作業者の作業スペースとすると、作業者の苗の供給時の動作が周辺の部材に妨げられることがなく、作業能率が向上する。 By disposing the medicine supply device 52 on one side of the seedling supply device 6 on the left and right sides of the machine body, the side and diagonally rear sides of the seedling supply device 6 on the left and right sides of the machine body form a space. When this space is used as a working space for a worker who takes seedlings from the seedling boxes 38 installed on the left and right sides of the machine out of the seedling boxes 38 loaded on the mounting table 30, and puts them into the seedling supply device 6, The work of supplying the seedlings of the person is not hindered by the surrounding members, and the work efficiency is improved.

また、苗の供給が安定するので、苗が植え付けられない欠株の発生が防止され、作業者が手作業で苗を植え付ける作業が不要になる。 Further, since the supply of seedlings is stable, the occurrence of shortages in which seedlings cannot be planted is prevented, and the operator does not need to manually plant seedlings.

上記の繰出装置53の左右の繰出ロール55,55には、繰出溝55aが所定間隔ごとに複数形成されており、この繰出溝55aの大きさにより、薬剤の繰出量が決められる。
しかしながら、本構成では薬剤供給装置52の動作を苗供給装置6と同調させる構成であるので、左右の繰出ロール55,55の回転速度を別途変更して薬剤の繰出量を変更することができない。
A plurality of feeding grooves 55a are formed at predetermined intervals on the left and right feeding rolls 55, 55 of the feeding device 53, and the amount of feeding the medicine is determined by the size of the feeding groove 55a.
However, in this configuration, since the operation of the medicine supply device 52 is synchronized with the seedling supply device 6, it is impossible to change the rotation speed of the left and right supply rolls 55, 55 separately to change the supply amount of the medicine.

上記の機構を搭載するとなると、部品点数の増加だけでなく、繰出量を変更しても苗供給装置6が植付装置7に苗を供給するタイミングを同調させる、極めて複雑な機構が必要になってしまう。 When the above-mentioned mechanism is mounted, not only an increase in the number of parts but also a very complicated mechanism that synchronizes the timing when the seedling feeding device 6 feeds the seedlings to the planting device 7 even if the feeding amount is changed is required. Will end up.

薬剤の繰出量の変更を簡潔にすべく、図6(a)、図6(b)に示すとおり、前記繰出ロール55に、前記繰出溝55aに加えて、各繰出溝55aの大きさを変更する調節シャッタ55cを、繰出ロール55の外周方向に移動可能に設ける。該調節シャッタ55cは、繰出溝55a内にスライド可能に配置され、上端面が繰出ロール55の外周面と略同じ高さとなる厚みとする。 In order to simplify the change of the delivery amount of the medicine, as shown in FIGS. 6A and 6B, in addition to the delivery groove 55a, the size of each delivery groove 55a is changed in the delivery roll 55. The adjusting shutter 55c is provided so as to be movable in the outer peripheral direction of the feeding roll 55. The adjusting shutter 55c is slidably arranged in the feeding groove 55a and has a thickness such that an upper end surface thereof has substantially the same height as an outer peripheral surface of the feeding roll 55.

上記により、繰出ロール55の調節シャッタ55cを摺動させると繰出溝55aの薬剤の収容量が変更されるので、使用する薬剤の種類や移植する苗に合わせて供給量の適切化を図ることができ、薬剤過多による苗や土壌の汚染が防止されると共に、薬剤不足による苗の病害や食害が防止される。 As described above, when the adjusting shutter 55c of the feeding roll 55 is slid, the amount of the medicine stored in the feeding groove 55a is changed. Therefore, the supply amount can be optimized according to the type of the medicine used and the seedling to be transplanted. Therefore, the seedlings and soil are prevented from being contaminated due to the excessive amount of the chemicals, and the diseases and feeding damages of the seedlings due to the lack of the chemicals are prevented.

前記載置台30は、回動苗枠36を機体左右他側に回動させることにより、苗箱38の積載数を増加させると共に、苗供給装置6の機体左右他側の側方で苗の供給作業を行う作業者に苗箱38を近付けるものである。しかしながら、回動苗枠36を展開しても苗箱38の積載数が4〜5個が限度であり、苗箱38の載置台30への補充作業頻度を少なくして作業能率を向上させることを目的とするときは、より多くの苗箱38を積載できる載置台30が必要になる。 The above-mentioned mounting table 30 increases the number of seedling boxes 38 to be loaded by rotating the rotating seedling frame 36 to the left and right sides of the machine body and supplies seedlings to the side of the left and right sides of the machine body of the seedling supply device 6. The seedling box 38 is brought closer to the worker who performs the work. However, even if the rotating seedling frame 36 is expanded, the number of seedling boxes 38 to be loaded is limited to 4 to 5, and the frequency of replenishing work of the seedling boxes 38 to the mounting table 30 is reduced to improve work efficiency. For this purpose, the mounting table 30 capable of loading more seedling boxes 38 is required.

上記の目的を達成すべく、図9から図12に示すとおり、側面視L字形状の左右の苗枠フレーム31,31及び左右の苗枠支柱32,32に替えて、鉛直姿勢の苗枠回動支軸131,131を植付伝動ケース24の上部に、左右方向に所定間隔を空けて各々配置する。 In order to achieve the above object, as shown in FIGS. 9 to 12, instead of the left and right seedling frame frames 31 and 31 and the left and right seedling frame columns 32 and 32 having an L-shaped side view, the seedling rotation in a vertical posture is performed. The drive shafts 131, 131 are arranged on the upper part of the planted transmission case 24 at predetermined intervals in the left-right direction.

そして、該左右の苗枠回動支軸131,131の上部には、第1回動ボス134を各々
設け、該左右の第1回動ボス134,134に第1回動アーム133を各々設け、該左右の第1回動アーム133,133の上部に第1回動苗載せ台132を各々設ける。該左右の第1回動苗載せ台132,132は、前記左右の第1回動アーム133,133の長手方向の中心位置に、第1回動軸135により回動可能に装着する。
Then, first turning bosses 134 are provided on the left and right seedling frame turning support shafts 131, 131, and first turning arms 133 are provided on the left and right first turning bosses 134, 134, respectively. The first rotating seedling stand 132 is provided on the left and right first rotating arms 133 and 133, respectively. The left and right first turning seedling mounting bases 132, 132 are rotatably mounted on the left and right first turning arms 133, 133 at the center positions in the longitudinal direction by a first turning shaft 135.

また、前記左右の第1ボス134,134の下方には、第2回動ボス138を各々設け、該左右の第2回動ボス138,138に第2回動アーム137を各々設け、該左右の第2回動アーム137,137の上部に第2回動苗載せ台136を各々設ける。該左右の第2回動苗載せ台136,136は、前記左右の第2回動アーム137,137の長手方向の中心位置に、第2回動軸139により回動可能に装着する。 Further, below the left and right first bosses 134, 134, second rotating bosses 138 are provided, and second left and right second rotating bosses 138, 138 are provided with second rotating arms 137, respectively. The second rotating seedling stand 136 is provided on the second rotating arms 137, 137, respectively. The left and right second turning seedling placing bases 136 and 136 are rotatably mounted on the left and right second turning arms 137 and 137 at the center positions in the longitudinal direction by a second turning shaft 139.

前記左右の第1ボス134,134と左右の第2ボス138,138の上下間には、左右の第1ボス134,134を上方に付勢する第1スプリング140,140を各々設け、左右の第2ボス138,138と左右の苗枠回動支軸131,131の上下間には、左右の第2ボス138,138を上方に付勢する第2スプリング141,141を各々設けて、第2載置台130を構成する。 First springs 140, 140 for urging the left and right first bosses 134, 134 upward are provided between the left and right first bosses 134, 134 and the left and right second bosses 138, 138, respectively. Second springs 141 and 141 for biasing the left and right second bosses 138 and 138 upward are provided between the upper and lower sides of the second bosses 138 and 138 and the left and right seedling frame rotation support shafts 131 and 131, respectively. The second mounting table 130 is configured.

これにより、左右の第1ボス134,134と左右の第2ボス138,138と左右の苗枠回動支軸131,131が互いに接触しないので、左右の第1回動苗載せ台132,132及び左右の第2回動苗載せ台136,136は自由に回動することができる。 As a result, the left and right first bosses 134, 134, the left and right second bosses 138, 138, and the left and right seedling frame rotation support shafts 131, 131 do not contact each other, so the left and right first rotation seedling mounting bases 132, 132 Also, the left and right second rotating seedling placing bases 136 and 136 can freely rotate.

なお、左右の第1回動アーム133,133及び第2回動アーム137,137は、左右の第1回動苗載せ台132,132及び左右の第2回動苗載せ台136,136の長手方向が機体前後方向を向く位置に回動させると、前記左右の苗枠回動支軸131,131から機体外側に向かう斜め姿勢となり、左右の第1回動苗載せ台132,132及び左右の第2回動苗載せ台136,136の長手方向が機体左右方向を向く位置に回動させると、前記左右の苗枠回動支軸131,131から機体後方に向かう斜め姿勢となる配置構成とする。言い換えれば、左右の第1回動アーム133,133及び第2回動アーム137,137は、左右の第1回動苗載せ台132,132及び左右の第2回動苗載せ台136,136の長手方向の対角線と重なる、あるいは対角線の近傍位置に配置される。 The left and right first rotating arms 133, 133 and the second rotating arms 137, 137 are the lengths of the left and right first rotating seedling mounting bases 132, 132 and the left and right second rotating seedling mounting bases 136, 136. When the direction is turned to a position facing the machine front-rear direction, the left and right first turning seedling placing bases 132, 132 and the left and right first turning seedling placing bases 132, 132 and the left and right first turning seedling mounting bases 132, 132 are inclined. When the longitudinal directions of the second rotating seedling placing bases 136 and 136 are rotated to a position in which the lateral direction of the machine body is oriented, the configuration is such that the left and right seedling frame rotation supporting shafts 131 and 131 are inclined to the rear of the machine body. To do. In other words, the left and right first rotating arms 133, 133 and the second rotating arms 137, 137 are the same as those of the left and right first rotating seedling mounting bases 132, 132 and the left and right second rotating seedling mounting bases 136, 136. It is arranged so as to overlap with the diagonal line in the longitudinal direction or in the vicinity of the diagonal line.

上記構成により、左右の第1回動苗載せ台132,132及び左右の第2回動苗載せ台136,136を用いて苗箱38を複数積載することができるので、苗の無くなった苗箱38を機外に下ろし、苗の入っている苗箱38を積載する積み下ろし作業の頻度が減少するので、作業能率が向上する。 With the above configuration, a plurality of seedling boxes 38 can be stacked using the left and right first rotating seedling mounting bases 132, 132 and the left and right second rotating seedling mounting bases 136, 136. Since the frequency of loading and unloading the seedling box 38 containing seedlings is reduced, the work efficiency is improved.

なお、左右の第1回動苗載せ台132,132と左右の第2回動苗載せ台136,136の上下間隔は殆ど無いので、苗箱38を積み込むときは、左右の第1回動苗載せ台132,132または左右の第2回動苗載せ台136,136のどちらか一方を機体後方に向けて回動させ、苗供給装置6の左右に展開して、作業者に苗箱38を近付ける。他方は、機体前後方向に長手方向が向いた状態のままとし、補充用の苗箱38を積載するものとする。 Since there is almost no vertical interval between the left and right first rotary seedling placing bases 132, 132 and the left and right second rotary seedling placing bases 136, 136, when loading the seedling box 38, the left and right first rotating seedling placing bases 132, 132. Either one of the mounting bases 132, 132 or the left and right second rotating seedling mounting bases 136, 136 is rotated toward the rear of the machine, and is deployed to the left and right of the seedling supply device 6 so that the operator can mount the seedling box 38. Get closer. On the other hand, with the longitudinal direction oriented in the machine front-rear direction, the supplementary seedling box 38 is loaded.

そして、苗を植え付けない移動時や機体の収納時には、左右の第1回動苗載せ台132,132と左右の第2回動苗載せ台136,136を機体前方に回動させることにより、第2載置台130の左右幅、即ち車体10から左右方向への突出量を抑えることができるので、接触による第2載置台130の破損が防止されると共に、第2載置第130を装着した状態での収納スペースの拡大が抑えられる。 Then, when the seedlings are moved without being planted or the body is stored, the left and right first rotating seedling mounting bases 132, 132 and the left and right second rotating seedling mounting bases 136, 136 are rotated to the front side of the body. Since the left-right width of the second mounting table 130, that is, the amount of protrusion from the vehicle body 10 in the left-right direction can be suppressed, damage to the second mounting table 130 due to contact is prevented, and the second mounting table 130 is mounted. The expansion of the storage space can be suppressed.

また、左右の第1回動苗載せ台132,132または左右の第2回動苗載せ台136,136を機体前方に回動させていても、エンジン2やミッションケース3の上方を覆わないので、メンテナンス作業時や燃料の補充時が行いやすく、作業能率が向上する。 Further, even when the left and right first rotary seedling mounting bases 132, 132 or the left and right second rotary seedling mounting bases 136, 136 are rotated forward of the machine body, the upper portions of the engine 2 and the mission case 3 are not covered. It is easy to perform maintenance work and refueling, improving work efficiency.

さらに、左右の第1回動苗載せ台132,132及び左右の第2回動苗載せ台136,136は、左右の第1回動アーム133,133及び第2回動アーム137,137上で各々回動することができるので、作業者は苗箱38を取り出しやすい角度に調節することができ、作業能率が向上すると共に、苗の供給ミスが防止され、苗が植え付けられない箇所の発生が防止される。 Further, the left and right first rotary seedling mounting bases 132, 132 and the left and right second rotary seedling mounting bases 136, 136 are provided on the left and right first rotating arms 133, 133 and the second rotating arms 137, 137. Since each can be rotated, the operator can adjust the seedling box 38 to an angle at which it can be easily taken out, work efficiency is improved, mistakes in supplying seedlings are prevented, and there are some places where seedlings cannot be planted. To be prevented.

なお、前記左右の苗枠回動支軸131,131の上部には、回転操作により左右の第1ボス134,134に上方から接近する、または上方に離間する回動調節ノブ142を各々設ける。該左右の回動調節ノブ142,142を操作して左右の第1ボス134,134を下方に押し下げることにより、左右の第1回動アーム133,133及び第2回動アーム137,137の回動を規制する構成とすると共に、逆方向に左右の回動調節ノブ142,142を操作することにより、左右の第1回動アーム133,133及び第2回動アーム137,137を回動可能にする構成とする。 Rotation adjusting knobs 142 are provided on the left and right seedling frame rotation support shafts 131, 131 to approach the left and right first bosses 134, 134 from above or separate them from each other by rotating operation. By operating the left and right rotation adjusting knobs 142, 142 to push down the left and right first bosses 134, 134, the left and right first rotating arms 133, 133 and the second rotating arms 137, 137 are rotated. It is possible to rotate the left and right first rotating arms 133 and 133 and the second rotating arms 137 and 137 by operating the left and right rotation adjusting knobs 142 and 142 in the opposite direction while being configured to restrict the movement. The configuration is set to.

これにより、作業中に左右の第1回動アーム133,133及び第2回動アーム137,137が機体の走行や振動により勝手に回動することを防止できるので、苗箱38が作業者から離れた位置に移動して苗の供給ができなくなることや、苗箱38が圃場に落下して苗が傷付くことが防止される。 As a result, it is possible to prevent the left and right first rotating arms 133, 133 and the second rotating arms 137, 137 from freely rotating due to traveling or vibration of the machine body during the work, so that the seedling box 38 can be protected from the operator. This prevents the seedlings from being moved to a distant position and being unable to supply seedlings, and the seedling box 38 falling to the field and damaging the seedlings.

上記の構成では、前記左右の第1回動苗載せ台132,132及び左右の第2回動苗載せ台136,136を機体前側に回動させた際、左右方向に間隔部が形成され、燃料の補充やエンジン2等のメンテナンス作業が妨げられない。但し、燃料の補充を行う位置や、エンジン2等を設けている位置よりも後方においては、この左右の間隔部はデッドスペースとなる。 In the above configuration, when the left and right first turning seedling placing bases 132, 132 and the left and right second turning seedling placing bases 136, 136 are turned to the front side of the machine body, a space is formed in the left and right direction, Fuel replenishment and maintenance work for the engine 2 etc. are not hindered. However, in the rear of the position where the fuel is replenished and the position where the engine 2 and the like are provided, the left and right spaces are dead spaces.

したがって、図13、図14に示すとおり、前記左右の苗枠回動支軸131,131の基部側で且つ機体前側に、支持台150を機体前方に向けて配置する。該支持台150には、植え付けた苗の周辺の土壌に供給する水を貯留する水や、補充用の燃料を収容するタンク151を積載するものとする。 Therefore, as shown in FIGS. 13 and 14, the support stand 150 is arranged on the front side of the machine body on the base side of the left and right seedling frame rotation support shafts 131, 131 and on the front side of the machine body. On the support table 150, water for storing water to be supplied to the soil around the planted seedlings and a tank 151 for storing refueling fuel are loaded.

該タンク151に貯留した水を用いるときは、この水を吸い上げ可能な電動ポンプを備える揚水装置152をタンク151に差し込み、該揚水装置152が吸い上げる水を植付装置7の植付ホッパ72の内部に案内する給水ホース153を設ける。 When the water stored in the tank 151 is used, a pumping device 152 equipped with an electric pump capable of sucking the water is inserted into the tank 151, and the water sucked by the pumping device 152 is placed inside the planting hopper 72 of the planting device 7. A water supply hose 153 for guiding the user is provided.

この給水ホース153から放出される水は、植付ホッパ72を通じて苗の植付位置に供給され、植え付け直後の苗が水不足で弱ることを防止する。また、植付ホッパ72の内部を水が通過することにより、苗の根鉢や、植付ホッパ72が苗を植え付ける際に付着した土を洗い流すことができるので、土が植付ホッパ72に収容された苗の姿勢が植付に適した姿勢から乱れることが防止され、植付後の苗の生育が良好になる。 The water discharged from the water supply hose 153 is supplied to the planting position of the seedling through the planting hopper 72 to prevent the seedling immediately after planting from being weakened due to water shortage. In addition, since the water passes through the inside of the planting hopper 72, the root pot of the seedling and the soil attached when the planting hopper 72 planted the seedling can be washed away, so that the soil is stored in the planting hopper 72. The posture of the planted seedlings is prevented from being disturbed from the posture suitable for planting, and the seedlings grow well after planting.

なお、前記薬剤供給装置52から薬剤を放出する案内ホース57を、植付ホッパ72の内部に配置し、植付ホッパ72が苗供給装置6から苗を受けて圃場に向かって下降し始めてから、土中に突入後に開いて苗を開放するまでに薬剤の供給を完了させる構成としてもよい。このとき、揚水装置152から吸い上げられた水が、薬剤の供給後に植付ホッパ72内に供給される構成とすると、植付ホッパ72内に張り付くなどして残っている薬剤を水で洗い落すことができるので、植え付けた苗に必要な量の薬剤を供給できると共に、他の植付位置に余分な量の薬剤が供給されることを防止できる。 A guide hose 57 for discharging the medicine from the medicine supply device 52 is arranged inside the planting hopper 72, and after the planting hopper 72 receives the seedlings from the seedling supplying device 6 and starts descending toward the field, It is also possible to adopt a configuration in which the supply of the drug is completed before the seedlings are opened by opening the soil after plunging into the soil. At this time, if the water sucked up from the water pumping device 152 is supplied to the inside of the planting hopper 72 after the supply of the medicine, the remaining medicine such as sticking to the inside of the planting hopper 72 may be washed off with water. Therefore, it is possible to supply the necessary amount of the drug to the planted seedlings and prevent the excessive amount of the drug from being supplied to other planting positions.
