Description

本発明は、生姜等の農作物を収穫する農作物収穫機に関するものである。 The present invention relates to a crop harvester that harvests crops such as ginger.

生姜などの農作物を収穫する場合、地上にのびる茎葉部をもって上方に引上げて地中にある最終収穫物を引上げる。この引上げ作業は重労働である。例えば、生姜を引上げる場合には、３０ｋｇ程度の引上げ力を要する。この引上げ作業を機械で行うものとして、従来、下記特許文献１に記載されるような、生姜等の農作物を引上げる農作物収穫機がある。この農作物収穫機は、左右にそれぞれ３輪づつで全部で６体の車輪を備え後部に歩行操縦用のハンドルを備えた走行装置と、作物体の茎葉部を挟持して引上げ搬送する後上がり傾斜に設けた引上げ搬送装置と、該引上げ搬送装置の挟持始端部上側に作物体の茎葉部を掻き込む掻き込みホイールを上下多数段に設けた掻き込み装置と、該掻き込み装置で掻き込んだ作物体の茎葉部を切断するカッターを上下複数段に設けた切断装置と、該切断装置で切断された葉先側の茎葉部を掻き込みホイールとガイド体によって掻き込み装置の一側方に放出する茎葉放出手段を設けた構成となっている。収穫作業時には、走行装置により作物体が植生されている畝を跨いだ状態で畝に沿って機体を自走させ、掻き込み装置により作物体の葉先側の茎葉部を掻き込むとともに、その下側の茎葉部を引上げ搬送装置により挟持する。掻き込まれた葉先側の茎葉部は、切断装置により上下複数箇所で切断され、茎葉放出手段によって機体側方に放出される。引上げ搬送装置に挟持された茎葉部は、機体の前進走行とともに後側上方に搬送されて地中にある最終収穫物が引上げられる。引上げ搬送装置の挟持搬送終端部から茎葉部が放出されると、作物体の上方への引上げ作用は解放されて畝上に放出される。切断装置により切断された茎葉部は、上記のように茎葉放出手段によって機体側方に放出されるので、畝上に放出された作物体が切断処理された茎葉部で覆われて畝上に放出された作物体が見えなくなることはなく、引上げ作業の後で作物体を回収するのに支障をきたすことがない。
特開２０００−３３３５２２号公報 When harvesting crops such as ginger, pull up the stems and leaves that extend above the ground to raise the final harvest in the ground. This pulling work is heavy labor.

At the time of harvesting work, the machine is self-propelled along the reed while straddling the reed on which the crop body is vegetated by the traveling device. The foliage on the side is lifted and pinched by the conveying device. The foliage portion on the leaf tip side that has been raked is cut at a plurality of upper and lower portions by a cutting device, and discharged to the side of the machine body by a foliage discharging means. The foliage sandwiched between the pulling and conveying devices is conveyed to the upper rear side as the machine moves forward, and the final harvest in the ground is pulled up. When the foliage part is released from the pinching and conveying terminal part of the lifting and conveying device, the upward lifting action of the crop body is released and released onto the straw. Since the foliage cut by the cutting device is released to the side of the machine by the foliage discharge means as described above, the crop that has been released on the straw is covered with the cut foliage and released onto the straw. The crops that have been removed will not disappear and will not interfere with the recovery of the crops after the pulling operation.

請求項２記載の発明は、前記案内体（４０，４０）の機体左右方向外側部を機体平面視で前記後輪（３）の後端部より機体前後方向後方で機体左右方向外側方に位置する個所まで延長し、該案内体（４０，４０）の機体左右方向外側部の機体左右方向内側に位置する前記操縦ハンドル（６）の側部を機体平面視で前記後輪（３）の後端部より後方で機体左右方向内側に位置するように配置して、前記案内体（４０，４０）の機体左右方向外側部とその左右方向内側の操縦ハンドル（６）との左右間で前記後輪（３，３）の後端部後方の領域に作業者が入り込んだ状態で立って位置することを可能に構成したことを特徴とする請求項１記載の農作物収穫機としたものである。 According to a second aspect of the present invention, the lateral body outer side portion of the guide body ( 40, 40 ) is located on the outer side in the lateral direction of the body from the rear end of the rear wheel ( 3 ) in the plan view of the rear wheel. The side of the steering handle ( 6 ) located on the inner side in the left and right direction of the fuselage in the left and right direction of the fuselage ( 40, 40 ) is rearward of the rear wheel ( 3 ) in plan view of the fuselage. arranged so as to be located inside the machine body transverse direction in the rear of the end portion, the rear between the left and right horizontal direction of the machine body outer side of the guide body (40, 40) and its lateral direction inside the steering wheel (6) The crop harvesting machine according to claim 1, wherein the crop harvester is configured to be able to stand in a state where an operator enters the area behind the rear end of the ring ( 3, 3 ) .

従って、この農作物収穫機は、左右の走行回転体３，３の駆動回転により前進走行する。圃場内に機体を移動させたら、作物体Ｐが植生する畝Ｕの左右両側方個所（畝両側の谷部）を左右の走行回転体３，３が通過するように機体を位置させ、機体が作物体Ｐが列状に植生する畝Ｕを跨ぐような状態として機体を前進させる。作業者は、走行回転体３の後方個所に立って移動する機体に追従して歩行移動する。機体の進行方向を変更するなどの操縦操作は、機体と共に歩行移動しながら機体の後部に設けた操縦ハンドル６をもって行う。そして、この農作物収穫機は、歩行操縦型の走行装置１によって機体を前進走行させ、引上げ搬送装置１５によって作物体Ｐの茎葉部ＰＬを挟持して引上げ搬送する。このとき土中にある作物体Ｐの最終収穫物Ｅも引上げられ、土中に張った根は引きちぎられる。そして、最終収穫物Ｅの底部が地表面より上方に上昇する前に切断装置１６によって茎葉部ＰＬが切断される。このため、最終収穫物Ｅはその上側に土等が被さった状態のままとなる。 Therefore, the crop harvester travels forward by driving rotation of the left and right traveling rotators 3 and 3. When the aircraft is moved into the field, the aircraft is positioned so that the left and right traveling rotators 3 and 3 pass through the left and right sides of the ridge U where the crop body P is vegetated (the valleys on both sides of the ridge). The aircraft is advanced in such a state that the crop bodies P straddle the ridges U vegetated in rows. The worker walks and moves following the airframe that stands and moves behind the traveling rotator 3. Maneuvering operations such as changing the advancing direction of the aircraft are performed with the steering handle 6 provided at the rear of the aircraft while walking along with the aircraft. In this crop harvesting machine, the machine body is moved forward by the walking maneuvering type travel device 1, and the pulling and transporting device 15 sandwiches the foliage part PL of the crop body P and transports it. At this time, the final harvest E of the crop body P in the soil is also raised, and the roots stretched in the soil are torn off. And the foliage part PL is cut | disconnected by the cutting device 16 before the bottom part of the last harvest E raises upwards from the ground surface. For this reason, the final harvested product E remains in a state where the upper side is covered with soil or the like .

切断装置１６により切断されて根本側部分Ｐ１から切り離された葉先側部分Ｐ２を引上げ搬送装置１５の終端個所Ｃから機体後方に排出する。そして、その排出された葉先側部分Ｐ２の茎葉部を茎葉受け台１７で受け、案内体４０，４０によって、引上げ搬送装置１５の後側から走行回転体３，３の後端部より機体前後方向前側を通って走行回転体３の左右外側方に至るように案内され、引上げ処理されてその上側に土等が被さった状態の最終収穫物Ｅの根本側部分Ｐ１から左右側方にずれた個所の圃場に切断処理された葉先側部分Ｐ２の茎葉部が排出される。作業者は、走行回転体３の後方を歩行移動するが、引上げ搬送装置１５の後側に排出された葉先側部分Ｐ２の茎葉部は、案内体４０，４０によって作業者の前方を通って機体外側方に案内されて行くことになり、切断処理された葉先側部分Ｐ２の茎葉部が作業者に倒れ掛かってくるようなことが生じにくい。 The leaf tip side portion P2 cut by the cutting device 16 and cut off from the root side portion P1 is pulled out from the terminal portion C of the pulling and conveying device 15 to the rear of the machine body. Then, the stems and leaves of the discharged leaf tip side portion P2 are received by the stems and leaves pedestal 17 and guided by the guide bodies 40 and 40 from the rear side of the traveling rotary body 3 and 3 from the rear end of the traveling rotary bodies 3 and 3 Guided so as to reach the left and right outer sides of the traveling rotator 3 through the front side in the direction, shifted to the left and right sides from the root side portion P1 of the final harvested product E that has been pulled up and covered with soil etc. The foliage portion of the leaf tip side portion P2 that has been subjected to the cutting process is discharged to the field of the place. The worker walks behind the traveling rotator 3, but the foliage portion of the leaf tip side portion P <b> 2 discharged to the rear side of the pulling and conveying device 15 passes through the front of the worker by the guide bodies 40 and 40. It will be guided to the outer side of the machine body, and it is unlikely that the foliage portion of the cut-off leaf-side portion P2 will fall on the operator.

また、前記案内体４０，４０の機体左右方向外側部を機体平面視で前記走行回転体３の後端部より機体前後方向後方で機体左右方向外側方に位置する個所まで延長し、該案内体４０，４０の機体左右方向外側部の機体左右方向内側に位置する前記操縦ハンドル６の側部を機体平面視で前記走行回転体３の後端部より後方で機体左右方向内側に位置するように配置することで、作業者は、案内体４０，４０の機体左右方向外側部とその左右方向内側の操縦ハンドル６との左右間で走行回転体３の後端部後方の領域に入り込んだ状態で立つことができる。これにより、作業者は、引上げ搬送装置１５の後側に排出された葉先側部分Ｐ２の茎葉部が引上げ搬送装置１５の後側及び案内体４０，４０の前側で詰まった状態になっていないかどうか容易に監視でき、且つ、詰まったときはそれを解消する対応を迅速に行え、しかも、そのような位置に作業者が立っていながらも、引上げ搬送装置１５の後側に排出された葉先側部分Ｐ２の茎葉部は、案内体４０，４０によって作業者の前方を通って機体外側方に案内されて行くので、切断処理された葉先側部分Ｐ２の茎葉部が作業者に倒れ掛かってくるようなことが生じにくい。 Further, the body left and right outer portions of the guide bodies 40, 40 are extended from the rear end portion of the traveling rotary body 3 to a position located on the outer side of the body left and right in the front-rear direction of the body in plan view, The side portions of the steering handle 6 located on the inner side in the left-right direction of the aircraft 40 and 40 in the left-right direction are positioned on the inner side in the left-right direction behind the rear end of the traveling rotary body 3 in plan view. By arranging, the operator enters the area behind the rear end of the traveling rotator 3 between the left and right sides of the outer side of the body 40 and 40 in the left and right direction and the steering handle 6 on the inner side in the left and right direction. I can stand. Thereby, the worker is not in a state where the foliage portion of the leaf tip side portion P2 discharged to the rear side of the lifting and conveying device 15 is clogged on the rear side of the lifting and conveying device 15 and the front side of the guide bodies 40 and 40. Whether it is easily monitored, and when it is clogged, it can be quickly dealt with, and while the worker is standing in such a position, the leaf discharged to the rear side of the pulling and conveying device 15 Since the foliage part of the front side part P2 is guided to the outside of the machine body by the guide bodies 40, 40 through the front of the operator, the foliage part of the cut front side part P2 falls on the operator. It is hard to happen.

請求項１記載の発明は、上記構成としたものなので、圃場に植生する生姜等の作物体Ｐを機械的に引上げ処理するもので収穫作業の省力化が図れるものであり、また、引上げ処理とともに収穫後に不要となる葉先側の茎葉部の切断処理が行え、しかも、引上げ処理されてその上側に土等が被さった状態の最終収穫物Ｅの上が切断処理された葉先側部分Ｐ２の茎葉部に覆われて見えなくなることがなく、引上げ処理後の作物体Ｐの根本側部分Ｐ１の回収作業も容易に行えて、作業能率の向上が図れるものである。また、切断手段と茎葉放出手段を簡易でコンパクトに構成でき、機体の前方視界も良く、機体の操縦性が良いものである。更に、機体と共に歩行移動する作業者に、切断処理された葉先側部分Ｐ２の茎葉部が倒れ掛かってくるようなことも生じにくい。 Since the invention according to claim 1 is configured as described above, it is possible to save the labor of the harvesting work by mechanically lifting the crop body P such as ginger vegetated on the field, and with the lifting process. The leaf tip side portion P2 of the leaf tip side portion P2 that can be cut after the harvesting and can be cut after the harvesting, and the top of the final harvested product E that has been pulled up and covered with soil etc. It is not covered with the foliage, and it can be easily recovered, and the work efficiency can be improved. Further, the cutting means and the foliage discharging means can be configured simply and compactly, the front view of the airframe is good, and the controllability of the airframe is good. Furthermore, it is difficult for an operator who walks and moves with the machine body to cause the stems and leaves of the cut-off leaf-side portion P2 to fall down.

また、この引上げ作業によって作物体Ｐは一度引上げられているので、軽い力で容易且つ迅速に取り上げることができ、また、完全に引き抜かれずに最終収穫物Ｅの上側に土等が被さった状態のままで残されているので、乾燥等による品質低下が生じにくい。 In addition, since the crop body P is pulled up once by this pulling operation, it can be picked up easily and quickly with a light force, and the soil is covered on the upper side of the final crop E without being completely pulled out. Since it is left as it is, quality deterioration due to drying or the like hardly occurs .

請求項２記載の発明は、上記構成としたものなので、請求項１記載の発明の効果を奏するとともに、案内体４０，４０の機体左右方向外側部とその左右方向内側の操縦ハンドル６との左右間で後輪３の後端部後方の領域に作業者が入り込んだ状態で立つことができ、これにより、作業者は引上げ搬送装置１５の後側に排出された葉先側部分Ｐ２の茎葉部が引上げ搬送装置１５の後側及び案内体４０，４０の前側で詰まった状態になっていないかどうか容易に監視でき、且つ、詰まったときはそれを解消する対応を迅速に行え、しかも、そのような位置に立っていながらも、引上げ搬送装置１５の後側に排出された葉先側部分Ｐ２の茎葉部は、案内体４０，４０によって作業者の前方を通って機体外側方に案内されて行くので、切断処理された葉先側部分Ｐ２の茎葉部が作業者に倒れ掛かってくるようなことが生じにくい。 Since the invention described in claim 2 has the above-described configuration, the effects of the invention described in claim 1 can be achieved, and the left and right outer portions of the guide bodies 40 and 40 and the left and right steering handles 6 can be connected to the left and right. The operator can stand in a state where the operator has entered the area behind the rear end of the rear wheel 3, so that the operator can remove the foliage of the leaf tip side portion P <b> 2 discharged to the rear side of the lifting and conveying device 15. Can be easily monitored whether it is clogged at the rear side of the pulling and conveying device 15 and the front side of the guide bodies 40, 40, and when it is clogged, it can be quickly dealt with, and the While standing in such a position, the foliage portion of the leaf tip side portion P2 discharged to the rear side of the pulling and conveying device 15 is guided to the outside of the machine body by the guide bodies 40 and 40 through the front of the operator. So go cut Foliage of the front-side portion P2 is less likely to occur is things like come hanging fell to the worker.

作業部Ｗには、作物体Ｐの茎葉部ＰＬを挟持して引上げ搬送する左右一対の引上げ搬送ベルト１４，１４を緩やかに後上がり傾斜した姿勢に設けた引上げ搬送装置１５と、作物体Ｐの茎葉部ＰＬを切断する切断装置１６を設けている。また、引上げ搬送装置１５は、機体平面視で左右の走行回転体２，２；３，３の間に配置するとともに、機体側面視で機体前部側から機体前後中間部付近にかけて後上がり傾斜姿勢で配置している。切断装置１６は、引上げ搬送装置１５の後部下側に配置している。更に、切断装置１６により切断されて根本側部分Ｐ１から切り離され引上げ搬送装置１５の後端部から排出される葉先側部分Ｐ２を受ける茎葉受け台１７を設け、該茎葉受け台１７の下側に、ミッションケース５の前部から機体前方へ後上がり姿勢で延びる左右のフレーム１９，１９を配置し、該左右のフレーム１９，１９とミッションケース５の下方に、前記切断装置１６により切断されて地面に落下した根本側部分Ｐ１を機体後方に通過可能とする空間部Ｓを有するように構成している。 In the working part W, a pair of left and right pulling and conveying belts 14 and 14 that lift and convey the foliage part PL of the crop body P are provided in a posture that is gently raised and inclined, A cutting device 16 for cutting the foliage part PL is provided. In addition, the pulling and conveying device 15 is disposed between the left and right traveling rotary bodies 2, 2; 3, 3 in a plan view of the airframe, and is tilted backward from the front side of the airframe to the vicinity of the airframe front and rear in the side view of the airframe. It is arranged with. The cutting device 16 is disposed below the rear portion of the pulling and conveying device 15. Further, a foliage pedestal 17 that receives the leaf tip side portion P2 cut by the cutting device 16 and cut from the root side portion P1 and discharged from the rear end portion of the pulling and conveying device 15 is provided. The left and right frames 19, 19 extending rearward from the front of the mission case 5 to the front of the aircraft are arranged, and the cutting device 16 cuts the left and right frames 19, 19 below the mission case 5. It is configured to have a space S that allows the root side portion P1 that has fallen to the ground to pass through the rear of the aircraft.

更に具体的な構成を説明する。ミッションケース５の前部に、左右の作業部伝動ケース１８，１８と、前方に前下がり傾斜で延びる左右２本のフレーム１９，１９の後端部を固着している。そして、引上げ搬送装置１５は、左右一対の上側の駆動プーリー２０，２０と左右一対の下側の従動プーリー２１，２１、左右の引上げ搬送ベルト１４，１４の内側から支持する複数のローラー２２，２２…を左右に設け、これら左右のプーリー及びローラの周りに、それぞれ引上げ搬送装置１５の搬送体となる引上げ搬送ベルト１４，１４を巻き掛け、左右の引上げ搬送ベルト１４，１４の外周面は機体の左右中央部において互いに接当する状態となるようにしている。そして、ミッションケース５内の動力が伝動フレーム１８，１８内の伝動手段を経て、駆動プーリー２０，２０の駆動側回転軸２３，２３に伝動して、左右の引上げ搬送ベルト１４，１４がその左右中央部側で互いに接当する作物体挟持箇所において機体後方側に移動するように周回駆動される構成としている。前記駆動プーリー２０，２０は、前記左右のフレーム１９，１９の左右間に配置し前記第一作業部伝動ケース１８，１８の下部に固着した第二作業部伝動ケース２４，２４から上方に突出させて支持した駆動側回転軸２３，２３に一体回転するように取付け、前記従動プーリー２１，２１は、前記フレーム１９，１９の前端部に固着した取付け部材から上方に突出させて回転自在に支持した従動側回転軸２５，２５に一体回転するように取付け、前記複数のローラー２２，２２…は、前記駆動側回転軸２３，２３と従動側回転軸２５，２５とにわたって装着された支持部材２６，２６に取付けた複数の支持軸に回転自在に取付けている。支持部材２６，２６は、引上げ搬送ベルト１４，１４の上側に配置しているので、引上げ搬送ベルト１４，１４で挟持搬送される作物体Ｐの茎葉部ＰＬに接触しにくくなっている。このため、作物体Ｐが生姜である場合に、引上げ搬送装置１５が茎葉部ＰＬを挟持搬送しているとき左右横方向に広がるように生育する土中の生姜を割ってしまうことが生じにくくなる。すなわち、地中の生姜が左右に広がって生育していて複数本の茎葉部ＰＬが左右に幅広く並んで生育しているとき、引上げ搬送装置１５は左右に林立する複数の茎葉部ＰＬの中間部付近を左右中央側一箇所に集めて挟持することになるが、このとき、複数のローラー２２，２２…を取り付ける支持部材を引上げ搬送ベルト１４，１４の下側に配置していて、複数のローラー２２，２２…を取り付ける支持部材の端部に左右両端側の茎葉部ＰＬが当たると、左右に広がった生姜の左右両端部を左右内側に引っ張る状態となって、これにより左右に広がった生姜を大きく湾曲させて割ってしまうことがある。しかしながら、本例では、複数のローラー２２，２２…を取り付ける支持部材２６，２６を引上げ搬送ベルト１４，１４の上側に配置しているので、このような問題を回避できる。 A more specific configuration will be described. The left and right working unit transmission cases 18 and 18 and the rear end portions of the two left and right frames 19 and 19 extending forward and inclined downward are fixed to the front portion of the mission case 5. The pulling and conveying device 15 includes a plurality of rollers 22 and 22 that are supported from the inside of the pair of left and right driving pulleys 20 and 20, the pair of left and right driven pulleys 21 and 21, and the left and right pulling and conveying belts 14 and 14. .. Are provided around the left and right pulleys and rollers, respectively, and the lifting and conveying belts 14 and 14 serving as the conveying members of the lifting and conveying device 15 are wound around the outer peripheral surfaces of the left and right pulling and conveying belts 14 and 14, respectively. The left and right central portions are in contact with each other. Then, the power in the transmission case 5 is transmitted to the drive-side rotary shafts 23 and 23 of the drive pulleys 20 and 20 through the transmission means in the transmission frames 18 and 18 so that the left and right pulling conveyor belts 14 and 14 are moved to the left and right. It is set as the structure driven so that it may move to a machine body back side in the crop body clamping location which mutually contacts on the center part side. The drive pulleys 20, 20 are disposed between the left and right frames 19, 19 and protrude upward from the second working part transmission cases 24, 24 fixed to the lower part of the first working part transmission cases 18, 18. The driven pulleys 21 and 21 are rotatably supported by projecting upward from mounting members fixed to the front end portions of the frames 19 and 19. The plurality of rollers 22, 22... Are attached to the driven side rotary shafts 25, 25 so as to rotate integrally therewith, and the support members 26, which are mounted across the drive side rotary shafts 23, 23 and the driven side rotary shafts 25, 25, A plurality of support shafts attached to 26 are rotatably attached. Since the support members 26 and 26 are disposed above the pulling and conveying belts 14 and 14, the supporting members 26 and 26 are less likely to come into contact with the foliage PL of the crop body P that is nipped and conveyed by the pulling and conveying belts 14 and 14. For this reason, when the crop body P is a ginger, it is less likely to break the ginger in the soil that grows in the horizontal direction when the pulling and conveying device 15 sandwiches and conveys the foliage part PL. . That is, when the ginger in the ground grows to the left and right and a plurality of foliage parts PL grows side by side widely, the lifting and conveying device 15 is an intermediate part of the plurality of foliage parts PL that stands on the left and right. In this case, the supporting members for attaching the plurality of rollers 22, 22... Are arranged below the pulling and conveying belts 14, 14, and the plurality of rollers are arranged. When the stems and leaves PL on the left and right ends hit the end of the support member to which 22, 22... Are attached, the left and right ends of the ginger that has spread to the left and right are pulled inward and left and right. It may be bent greatly. However, in this example, since the supporting members 26 and 26 to which the plurality of rollers 22 are attached on the upper side of the pulling and conveying belts 14 and 14, such a problem can be avoided.

引上げ搬送装置１５の挟持始端箇所Ａは、左右の引上げ搬送ベルト１４，１４が左右中央側前部でベルト外周面を互いに接触させ始める個所となり、機体の前進走行中に、この挟持始端部に作物体Ｐの茎葉部ＰＬが入り込んでくると、左右の引上げ搬送ベルト１４，１４が作物体Ｐの茎葉部ＰＬを挟んで後側斜め上方に搬送する。引上げ搬送ベルト１４，１４の機体後方水平方向の移動速度は、作業時の機体前進速度（走行変速装置ＶＣを低速前進伝動状態としたときの速度）と略同じ大きさの速度になるように設定しているので、機体が前進走行していても、引上げ搬送装置１５に挟持搬送される作物体Ｐは畝Ｕに対して前後に倒れず略垂直姿勢のままで上方に引上げ作用を受けることになる。引上げ搬送装置１５の挟持終端箇所は、引上げ搬送装置１５の後端部にあって左右の引上げ搬送ベルト１４，１４が左右中央側後部でベルト外周面が互いに離れ始める個所となり、左右の引上げ搬送ベルト１４，１４が挟持搬送した作物体Ｐの茎葉部ＰＬがこの箇所から排出される。なお、引上げ搬送ベルト１４，１４の機体後方水平方向の移動速度を、作業時の機体前進速度（走行変速装置ＶＣを低速前進伝動状態としたときの速度）よりも１０〜２０％速い速度に設定すると、地中で互いに繋がった状態にある生姜の塊群を機体前進方向前側から引上げるように作用することになり、引上げ時に生姜の塊群が割れるのを生じにくくすることができる。 The gripping start end portion A of the pulling and conveying device 15 is a place where the left and right pulling and transporting belts 14 and 14 start contacting the belt outer peripheral surfaces with each other at the front side of the left and right center side. When the foliage portion PL of the body P enters, the left and right pulling conveyance belts 14 and 14 convey the slant portion PL of the crop body P diagonally upward on the rear side. The moving speed of the pulling conveyor belts 14 and 14 in the rear horizontal direction of the airframe is set to be substantially the same speed as the airframe forward speed during operation (the speed when the traveling transmission device VC is in the low speed forward transmission state). Therefore, even if the machine is traveling forward, the crop body P sandwiched and transported by the pulling and transporting device 15 does not fall back and forth with respect to the ridge U and is subjected to a lifting action in a substantially vertical posture. Become. The clamping end point of the pulling and conveying device 15 is located at the rear end of the pulling and conveying device 15, where the left and right pulling and conveying belts 14 and 14 are the rear portions on the left and right central sides, and the belt outer peripheral surfaces begin to separate from each other. The foliage part PL of the crop body P which 14 and 14 pinched and conveyed is discharged | emitted from this location. The moving speed of the pulling conveyor belts 14 and 14 in the rear horizontal direction is set to a speed that is 10 to 20% faster than the forward speed of the airframe during work (the speed when the traveling transmission device VC is in the low speed forward transmission state). Then, it acts to pull up the ginger lump groups that are connected to each other in the ground from the front side in the forward direction of the aircraft, and it is difficult to cause the ginger lump groups to break when pulled up.

引上げ搬送ベルト１４，１４の左右一方側を他方側に対して離れる方向に移動可能に構成している。具体的には、左右一方側の引上げ搬送ベルト１４を駆動プーリ２０の回転軸２３を軸に支持部材２６の前側を左右方向外側に回動可能に設けている。作業時は引上げ搬送ベルト１４，１４が互いに接当状態となる位置で固定する固定手段を設け、該固定手段の固定を解除することで左右方向外側への回動が可能となる。これにより、引上げ搬送ベルト１４，１４の間に過大な量の茎葉部ＰＬが入り込んで過負荷状態となってエンジン４が停止してしまったときなどに、引上げ搬送ベルト１４，１４の間に詰まった茎葉部ＰＬを容易に取り除くことができる。ところで、図中の１５ａは、引上げ搬送装置１５の上側を覆うカバーである。 The left and right sides of the pulling conveyor belts 14 and 14 are configured to be movable in a direction away from the other side. Specifically, the pulling conveyance belt 14 on one side of the left and right sides is provided so as to be able to turn the front side of the support member 26 outward in the left-right direction around the rotation shaft 23 of the drive pulley 20. At the time of work, fixing means for fixing the pulling conveyance belts 14 and 14 at positions where they are in contact with each other is provided, and the fixing means is released so that it can be turned outward in the left-right direction. As a result, when an excessive amount of foliage portion PL enters between the pulling and conveying belts 14 and 14 and the engine 4 is stopped due to an overload, the jamming is caused between the pulling and conveying belts 14 and 14. The foliage PL can be easily removed. Incidentally, reference numeral 15a in the figure denotes a cover that covers the upper side of the pulling and conveying device 15.

左右の前輪２，２は、上下調節可能に設けている。左右の前輪２，２を下方に位置調節すると、引上げ搬送装置１５の前下がり傾斜が大きくなって、作物体引上げ高さＨが増大し、左右の前輪２，２を上方に位置調節すると、引上げ搬送装置１５の前下がり傾斜が小さくなって、作物体引上げ高さＨが小さくなる。従って、左右の前輪２，２の上下調節機構によって引上げ搬送装置１５の作物体引上げ高さＨを設定調節可能となっている。具体的には、左右の前輪２，２は、前記フレーム１９，１９の前端部左右両側部に取り付けた前輪支持軸２７，２７の左右両端部の前輪支持アーム取付け部２８，２８に、上下に延びる前輪支持アーム２９，２９を装着し、その下端部に前輪車軸３０，３０を設け、これに左右の前輪２，２を回転自在に取り付けている。左右の前輪２，２の上下調節機構は、前輪支持アーム取付け部２８，２８に対する前輪支持アーム２９，２９の取付け高さを調節可能とすることで構成している。図例では、取付け穴と取付けピンで構成しているが、他の構成によって実現してもよい。 The left and right front wheels 2 and 2 are provided so as to be vertically adjustable. When the left and right front wheels 2 and 2 are adjusted downward, the forward lowering inclination of the lifting and conveying device 15 is increased, the crop body lifting height H is increased, and when the left and right front wheels 2 and 2 are adjusted upward, the lifting is increased. The forward downward inclination of the conveying device 15 is reduced, and the crop body lifting height H is reduced. Accordingly, the crop body lifting height H of the lifting and conveying device 15 can be set and adjusted by the vertical adjustment mechanism of the left and right front wheels 2 and 2. Specifically, the left and right front wheels 2 and 2 are vertically moved to front wheel support arm mounting portions 28 and 28 at both left and right ends of the front wheel support shafts 27 and 27 attached to the left and right sides of the front end portion of the frames 19 and 19. Extending front wheel support arms 29 and 29 are mounted, front wheel axles 30 and 30 are provided at lower ends thereof, and left and right front wheels 2 and 2 are rotatably attached thereto. The vertical adjustment mechanism of the left and right front wheels 2 and 2 is configured by making it possible to adjust the mounting height of the front wheel support arms 29 and 29 with respect to the front wheel support arm mounting portions 28 and 28. In the example shown in the figure, the mounting hole and the mounting pin are used, but other configurations may be used.

切断装置１６は、左右一対の円盤状カッターを左右中央部で一部上下に重なるようにして引上げ搬送装置１５の後部下側に設けた構成としている。切断装置１６の左右の円盤状カッターは、ミッションケース５内からの動力を第一作業部伝動ケース１８及び第二作業部伝動ケース２４，２４内の伝動手段を介して円盤状カッターの回転軸３１，３１に伝動して駆動回転している。左右の引上げ搬送ベルト１４，１４によって挟持搬送される作物体Ｐの茎葉部ＰＬは、その挟持搬送終端個所Ｃまで搬送される手前でその挟持搬送通路を遮るように配置された駆動回転する左右の円盤状カッターで切断作用を受けて切断される。左右の円盤状カッターの前側外周が交差する個所に作物体Ｐの茎葉部ＰＬが搬送されるように設定しているので、ここから切断が開始される。そして、引上げ搬送装置１５の挟持始端箇所Ａから切断装置１６が茎葉部ＰＬを切断する時点の引上げ搬送装置１５の挟持箇所Ｂまでの作物体引上げ高さＨを、引上げ搬送装置１５が作用する前で地中に生育していた作物体Ｐの最終収穫物Ｅの最大深さｄより小さくなるように設定している。具体的には、作物体引上げ高さＨを２〜６ｃｍに設定する。なお、切断装置１６を左右のフレーム１９，１９より下側に位置するように配置することもできる。このようにすると、切断装置１６であるカッターの交換がフレーム１９，１９に妨げられず容易に行え、また、切断された後の根本側部分Ｐ１がフレーム１９，１９に引っかかって引きずって行くようなことが生じにくくなり、一層適確な作業が行える。 The cutting device 16 has a configuration in which a pair of left and right disc-shaped cutters are provided below the rear portion of the pulling and conveying device 15 so as to partially overlap each other at the left and right central portions. The left and right disk-shaped cutters of the cutting device 16 transmit the power from within the mission case 5 via the first working part transmission case 18 and the transmission means in the second working part transmission cases 24, 24. , 31 is driven to rotate. The foliage PL of the crop body P sandwiched and transported by the left and right lifting and transporting belts 14 and 14 is arranged to block the sandwiched transport path before being transported to the sandwiching and transporting end point C. It is cut by receiving a cutting action with a disk-shaped cutter. Since the setting is made so that the foliage part PL of the crop body P is conveyed to the place where the front outer circumferences of the left and right disc-shaped cutters intersect, cutting is started from here. Then, before the lifting and conveying device 15 acts, the crop body lifting height H from the clamping starting end portion A of the lifting and conveying device 15 to the clamping point B of the lifting and conveying device 15 at the time when the cutting device 16 cuts the foliage part PL. Is set to be smaller than the maximum depth d of the final harvest E of the crop body P that has grown in the ground. Specifically, the crop body lifting height H is set to 2 to 6 cm. Note that the cutting device 16 may be arranged to be positioned below the left and right frames 19, 19. In this way, the cutter as the cutting device 16 can be easily replaced without being obstructed by the frames 19, 19, and the root side portion P1 after being cut is caught by the frames 19, 19 and drags. This makes it less likely to occur and enables more accurate work.

従って、この農作物収穫機は、歩行操縦型の走行装置１によって機体を前進走行させ、引上げ搬送装置１５によって作物体Ｐの茎葉部ＰＬを挟持して引上げ搬送する。このとき土中にある作物体Ｐの最終収穫物Ｅも引上げられ、土中に張った根は引きちぎられる。そして、最終収穫物Ｅの底部が地表面より上方に上昇する前に切断装置１６によって茎葉部ＰＬが切断される。このため、最終収穫物Ｅはその上側に土等が被さった状態のままとなる。切断装置１６により切断された後の作物体Ｐの根本側部分Ｐ１は、左右のフレーム１９，１９及びミッションケース５の下方に形成された空間部Ｓを通って機体後方に通過していく。このような作業を行った後、圃場に残された作物体Ｐの根本側部分Ｐ１は、作業者によって圃場から引き抜かれて最終収穫物Ｅが回収されるが、前記作業によって一度引上げられているので、軽い力で容易且つ迅速に取り上げることができ、また、完全に引き抜かれずに最終収穫物Ｅの上側に土等が被さった状態のままで残されているので、乾燥等による品質低下が生じにくい。一方、切断装置１６によって切断されて根本側部分Ｐ１から切り離された葉先側部分Ｐ２は、引上げ搬送装置１５の後端部から排出され、案内体４０，４０に案内されて機体左右方向外側方に放出される。 Therefore, this crop harvesting machine moves the machine forward by the walking maneuvering type traveling device 1, and lifts and conveys the foliage part PL of the crop body P by the pulling and conveying device 15. At this time, the final harvest E of the crop body P in the soil is also raised, and the roots stretched in the soil are torn off. And the foliage part PL is cut | disconnected by the cutting device 16 before the bottom part of the last harvest E raises upwards from the ground surface. For this reason, the final harvested product E remains in a state where the upper side is covered with soil or the like. The root-side portion P1 of the crop body P after being cut by the cutting device 16 passes through the left and right frames 19 and 19 and the space portion S formed below the mission case 5 to the rear of the machine body. After performing such work, the root side portion P1 of the crop body P left in the field is pulled out of the field by the operator and the final harvest E is collected, but has been pulled up once by the work. Therefore, it can be picked up easily and quickly with a light force, and it is not pulled out completely, but is left with the soil etc. covered on the upper side of the final harvest E, resulting in a decrease in quality due to drying, etc. Hateful. On the other hand, the leaf tip side portion P2 cut by the cutting device 16 and cut off from the root side portion P1 is discharged from the rear end portion of the pulling and conveying device 15 and guided by the guide bodies 40, 40 to the outer side in the lateral direction of the machine body. To be released.

この農作物収穫機は、前記切断装置１６により切断されて根本側部分Ｐ１から切り離された葉先側部分Ｐ２を引上げ搬送装置１５の終端個所Ｃから機体後方に排出する。そして、その排出された葉先側部分Ｐ２の茎葉部を受ける茎葉受け台１７を設けている。本例において、この茎葉受け台１７は、具体的には、引上げ搬送装置１５の挟持搬送終端個所Ｃの下方箇所から機体の左右両外側に向けて広がる板面を有する板体３２で形成している。この茎葉受け台１７は、引上げ搬送装置１５の挟持搬送終端個所Ｃから放出された葉先側部分Ｐ２の茎葉部を下方から支持するように受け、そして、案内体４０，４０に案内されてその茎葉部を機体の左右外側方の圃場に（畝両側の谷部に）放出される。なお、茎葉受け台１７の後側に、第一作業部伝動ケース１８、ミッションケース５、エンジン４の上側を覆うカバー部３３を形成している。 In this crop harvesting machine, the leaf tip side part P2 cut by the cutting device 16 and cut off from the root side part P1 is pulled up and discharged from the terminal portion C of the transporting device 15 to the rear of the machine body. And the foliage stand 17 which receives the foliage part of the discharged leaf tip side part P2 is provided. In this example, specifically, the foliage pedestal 17 is formed of a plate body 32 having plate surfaces that extend from the lower part of the clamping conveyance terminal part C of the pulling conveyance apparatus 15 toward the left and right outer sides of the machine body. Yes. The foliage pedestal 17 receives the foliage portion of the leaf tip side portion P2 discharged from the clamping conveyance terminal portion C of the pulling conveyance device 15 from below, and is guided by the guide bodies 40, 40 to The foliage is discharged to the fields on the left and right outside of the aircraft (to the valleys on both sides of the heel). A cover portion 33 that covers the first working portion transmission case 18, the transmission case 5, and the upper side of the engine 4 is formed on the rear side of the foliage pedestal 17.

そして、この農作物収穫機は、歩行操縦用の操縦ハンドル６を機体の後部に設け、駆動回転して機体を前進走行させる走行回転体３，３を機体の左右両側に設け、機体の前進走行中に作物体Ｐの茎葉部ＰＬを挟持して後側上方に搬送し作物体Ｐを引上げる引上げ搬送装置１５を前記左右走行回転体３，３より機体左右方向内側に設け、作物体Ｐの茎葉部ＰＬを切断する切断装置１６を前記引上げ搬送装置１５の後部下側に設け、前記引上げ搬送装置１５の後側に排出された茎葉部Ｐ２を機体側方に案内する案内体４０，４０を設けたものである。 This crop harvester is provided with a steering handle 6 for maneuvering at the rear of the aircraft, and is provided with traveling rotators 3 and 3 for driving and rotating the aircraft to move forward on both the left and right sides of the aircraft. A lifting and transporting device 15 that sandwiches the foliage portion PL of the crop body P and conveys it to the rear upper side and pulls up the crop body P is provided on the inner side in the lateral direction of the left and right traveling rotary bodies 3 and 3. A cutting device 16 for cutting the part PL is provided below the rear portion of the pulling and conveying device 15, and guide bodies 40 and 40 are provided for guiding the foliage P2 discharged to the rear side of the pulling and conveying device 15 to the side of the machine body. It is a thing.

そして、案内体４０，４０は、前記引上げ搬送装置１５の後側から前記走行回転体３，３の後端部より機体前後方向前側を通って前記走行回転体３，３の左右外側方に至るように設けている。また、案内体４０，４０の機体左右方向外側部４０ａ，４０ａを機体平面視で左側後輪３の後端部より機体前後方向後方で機体左右方向外側方に位置する個所まで延長し、該案内体４０，４０の機体左右方向外側部４０ａ，４０ａの機体左右方向内側に位置する操縦ハンドル６の側部（左側把持部９）を機体平面視で左側後輪３の後端部より後方で機体左右方向内側に位置するように配置して、前記案内体４０，４０の機体左右方向外側部４０ａ，４０ａとその左右方向内側の操縦ハンドル６（左側把持部９）との左右間で左側後輪３の後端部後方の領域に作業者が入り込んだ状態で立って位置することを可能に構成している。更にまた、案内体４０，４０を、上下二段で機体左右方向内側から機体左右方向外側に延びるように設けた棒状部材で構成している。なお、図例では、案内体４０，４０は、引上げ搬送装置１５の後側右寄り個所から上方に立ち上がる支柱４１を設け、この支柱４１に、上下に適宜設定した上下間隔で、機体側方に延びる上下の案内体４０，４０を取り付けている。また、上下の案内体４０，４０の上下間は、支柱４１から左右外側方に向けて解放状態に設けている、即ち、上下の案内体４０，４０は、支柱４１への取付個所から各機体左右方向外側部４０ａ，４０ａに至るまで上下互いに連結していない構成なので、案内体４０，４０の後方に位置する作業者が上下の案内体４０，４０の間を通して手を前方に延ばして案内体４０，４０の前側に位置する茎葉部を掴むことができるので、作業者が強制的に葉先側部分Ｐ２の茎葉部を掴んで機体側方に移動させて排出するときに手や腕を容易に動かすことができて、その排出作業が容易且つ迅速に行え、作業能率の向上が図れる。また、案内体４０，４０を、作業時には上記の状態となる作業位置に位置可能に構成し、機体の運搬時や格納時などには、案内体４０，４０の機体からのはみ出し量が少なくなる格納位置に移動可能に設けることもできる。具体的には、例えば、案内体４０，４０を支柱４１を軸に前方或は後方に回動可能に構成することで容易にそれが実現できる。 The guide bodies 40, 40 extend from the rear side of the pulling and conveying device 15 to the left and right outer sides of the traveling rotators 3, 3 from the rear end portions of the traveling rotators 3, 3 through the front side in the longitudinal direction of the body. It is provided as follows. Further, the body left and right outer side portions 40a and 40a of the guide bodies 40 and 40 are extended from the rear end portion of the left rear wheel 3 to a position located on the outer side in the body left and right direction in the front-and-rear direction of the body in plan view. The side of the steering handle 6 (the left grip 9) located inside the left and right outer sides 40a and 40a of the bodies 40 and 40 is located behind the rear end of the left rear wheel 3 in plan view. The left rear wheel is disposed between the left and right sides of the left and right outer portions 40a and 40a of the airframe body of the guide bodies 40 and 40 and the steering handle 6 (left grip portion 9) on the inner side in the left and right direction. 3 is configured to be able to stand in a state where an operator enters the area behind the rear end of the rear end. Furthermore, the guide bodies 40, 40 are constituted by rod-like members provided so as to extend from the inner side in the left and right direction of the body to the outer side in the left and right direction of the body in two stages. In the example shown in the figure, the guide bodies 40 are provided with a support column 41 that rises upward from a position on the right side of the rear side of the pulling and conveying device 15, and the support column 41 extends to the side of the machine body at an appropriate vertical interval. Upper and lower guide bodies 40 are attached. In addition, the upper and lower guide bodies 40, 40 are provided in a released state from the support column 41 toward the left and right outer sides, that is, the upper and lower guide bodies 40, 40 are connected to the support column 41 from the respective locations. Since it is the structure which is not mutually connected up and down until it reaches the left-right direction outer side part 40a, 40a, the operator located behind the guide bodies 40 and 40 extends a hand forward between the upper and lower guide bodies 40 and 40, and guide body 40 and 40 can grasp the foliage portion located on the front side, so the operator can easily grasp the foliage portion of the leaf tip side portion P2 and move it to the side of the machine to eject it easily. Therefore, the discharging operation can be performed easily and quickly, and the working efficiency can be improved. In addition, the guide bodies 40, 40 are configured to be positioned at the work position that is in the above state during work, and the amount of protrusion of the guide bodies 40, 40 from the machine body is reduced when the machine is transported or stored. It can also be provided movably at the storage position. Specifically, for example, this can be easily realized by configuring the guide bodies 40, 40 so as to be pivotable forward or backward about the support column 41.

従って、この農作物収穫機は、左右の走行回転体３，３の駆動回転により前進走行する。圃場内に機体を移動させたら、作物体Ｐが植生する畝Ｕの左右両側方個所（畝両側の谷部）を左右の走行回転体３，３が通過するように機体を位置させ、機体が作物体Ｐが列状に植生する畝Ｕを跨ぐような状態として機体を前進させる。作業者は、走行回転体３の後方個所に立って移動する機体に追従して歩行移動する。機体の進行方向を変更するなどの操縦操作は、機体と共に歩行移動しながら機体の後部に設けた操縦ハンドル６をもって行う。そして、機体の前進走行中に、左右走行回転体３，３より機体左右方向内側に設けた引上げ搬送装置１５が作物体Ｐの茎葉部ＰＬを挟持して後側上方に搬送し地中にある作物体Ｐの最終収穫物Ｅを引上げる。また、引上げ搬送装置１５の後部下側に設けた切断装置１６が引上げ搬送装置１５の挟持個所より下側の茎葉部ＰＬを切断する。切断装置１６が茎葉部ＰＬを切断すると、引上げ搬送装置１５による作物体Ｐの上方への引上げ作用は解放され、切断個所より下側部分の作物体Ｐ１は畝Ｕ上に放出される。一方、切断個所より上側部分の茎葉部Ｐ２は、引上げ搬送装置１５によってその搬送終端部まで搬送され排出される。引上げ搬送装置１５の後側に排出された茎葉部Ｐ２は、案内体４０，４０によって、引上げ搬送装置１５の後側から走行回転体３，３の後端部より機体前後方向前側を通って走行回転体３の左右外側方に至るように案内され、引上げ処理されて畝Ｕ上に放出された作物体Ｐ１から左右側方にずれた個所の圃場に切断処理された茎葉部Ｐ２が排出される。よって、この農作物収穫機は、圃場に植生する生姜等の作物体Ｐを機械的に引上げ処理するもので収穫作業の省力化が図れるものであり、また、引上げ処理とともに収穫後に不要となる葉先側の茎葉部Ｐ２の切断処理が行え、しかも、引上げ処理されて畝Ｕ上に放出された作物体Ｐ１が切断処理された茎葉部Ｐ２に覆われて見えなくなることがなく、引上げ処理後の作物体Ｐ１の回収作業も容易に行えて、作業能率の向上が図れるものである。また、切断手段と茎葉放出手段を簡易でコンパクトに構成でき、機体の前方視界も良く、機体の操縦性が良いものである。更に、機体と共に歩行移動する作業者に、切断処理された茎葉部Ｐ２が倒れ掛かってくるようなことも生じにくい。 Therefore, the crop harvester travels forward by driving rotation of the left and right traveling rotators 3 and 3. When the aircraft is moved into the field, the aircraft is positioned so that the left and right traveling rotators 3 and 3 pass through the left and right sides of the ridge U where the crop body P is vegetated (the valleys on both sides of the ridge). The aircraft is advanced in such a state that the crop bodies P straddle the ridges U vegetated in rows. The worker walks and moves following the airframe that stands and moves behind the traveling rotator 3. Maneuvering operations such as changing the advancing direction of the aircraft are performed with the steering handle 6 provided at the rear of the aircraft while walking along with the aircraft. During the forward traveling of the body, the pulling and conveying device 15 provided on the inner side in the left and right direction of the body from the left and right traveling rotators 3 and 3 sandwiches the foliage part PL of the crop body P and transports it to the upper rear side and is in the ground. The final harvest E of the crop body P is pulled up. Further, the cutting device 16 provided on the lower rear side of the pulling and conveying device 15 cuts the foliage portion PL below the pinching portion of the pulling and conveying device 15. When the cutting device 16 cuts the foliage part PL, the lifting action of the crop body P by the pulling and conveying device 15 is released, and the crop body P1 in the lower part from the cutting point is discharged onto the ridge U. On the other hand, the foliage P2 in the upper part from the cut portion is transported to the transport terminal by the pulling transport device 15 and discharged. The foliage P2 discharged to the rear side of the pulling and conveying device 15 travels from the rear side of the pulling and conveying device 15 through the front side in the front-rear direction of the machine body from the rear ends of the traveling rotary members 3 and 3 by the guide bodies 40 and 40. The foliage P2 that has been subjected to cutting processing is discharged to a farm field that is guided to reach the left and right outer sides of the rotator 3 and is shifted to the left and right sides from the crop body P1 that has been pulled up and released onto the basket U. . Therefore, this crop harvesting machine mechanically lifts the crop body P such as ginger planted in the field and can save labor of the harvesting work. In addition, the leaf tip which becomes unnecessary after the harvesting together with the lifting process. The crop body P1 that has been subjected to the cutting process can be cut, and the crop body P1 that has been pulled up and released onto the ridge U is not covered with the cut leaves and leaves P2 and cannot be seen. The collection work of the body P1 can be easily performed, and the work efficiency can be improved. Further, the cutting means and the foliage discharging means can be configured simply and compactly, the front view of the airframe is good, and the controllability of the airframe is good. Furthermore, it is difficult for an operator who walks and moves together with the machine body to cause the cut leaves P2 to fall down.

また、作業者は、案内体４０，４０の機体左右方向外側部とその左右方向内側の操縦ハンドル６との左右間で走行回転体３の後端部後方の領域に入り込んだ状態で立つことができる。これにより、作業者は、引上げ搬送装置１５の後側に排出された茎葉部Ｐ２が引上げ搬送装置１５の後側及び案内体４０，４０の前側で詰まった状態になっていないかどうか容易に監視でき、且つ、詰まったときはそれを解消する対応を迅速に行え、しかも、そのような位置に作業者が立っていながらも、引上げ搬送装置１５の後側に排出された茎葉部Ｐ２は、案内体４０，４０によって作業者の前方を通って機体外側方に案内されて行くので、切断処理された葉先側の茎葉部Ｐ２が作業者に倒れ掛かってくるようなことが生じにくい。 Further, the worker can stand in a state of entering the region behind the rear end of the traveling rotator 3 between the left and right sides of the body 40 in the left-right direction and the steering handle 6 inside in the left-right direction. it can. Thus, the operator can easily monitor whether the foliage P2 discharged to the rear side of the pulling and conveying device 15 is clogged on the rear side of the pulling and conveying device 15 and the front side of the guide bodies 40 and 40. When it is clogged, it is possible to quickly deal with it, and the foliage P2 discharged to the rear side of the pulling and conveying device 15 while the operator is standing at such a position is guided. Since the bodies 40 and 40 are guided to the outside of the machine body through the front of the operator, it is unlikely that the foliage portion P2 on the leaf tip side that has been subjected to the cutting process will fall on the operator.

更に、前記案内体４０，４０を、上下二段で機体左右方向内側から機体左右方向外側に延びるように設けた棒状部材で構成したことにより、機体構成の簡略化が更に図れ、また、機体の前方視界も更に良好になって、機体の操縦性が更に良好になる。 Further, the guide body 40, 40 is composed of a rod-shaped member provided so as to extend from the inner side in the left and right direction of the body to the outer side in the left and right direction of the body in two upper and lower stages, thereby further simplifying the structure of the body. The forward visibility is further improved, and the controllability of the aircraft is further improved.

また、この農作物収穫機は、機体後部にエンジン４を配置し、該エンジン４の前側にミッションケース５を配置し、該ミッションケース５の前部に機体前方へ後上がり姿勢で延びる左右のフレーム１９，１９を固着し、該フレーム１９，１９の上側に前記引上げ搬送装置１５を配置し、前記ミッションケース５の左右両側部に走行回転体３，３を駆動する動力を伝動する伝動部材を内装しミッションケース５の底部より下側に延設される伝動ケース７，７を介して左右の後輪３，３を装着した構成としている。また、茎葉受け台１７は、左右のフレーム１９，１９の上側に配置している。これにより、畝Ｕを跨いで走行する機体の左右のフレーム１９，１９とミッションケース５の下方に、切断装置１６により切断され畝Ｕに残される根本側部分Ｐ１を機体後方に通過可能とする空間部Ｓを機体底部に充分に確保することができる。従って、機体がコンパクトに構成されるものでありながら、畝Ｕ上に着地した根本側部分Ｐ１を、大きく倒したり引きずったりせずに機体後方に通過させられ、しかも、切断された葉先側部分Ｐ２が根本側部分Ｐ１の上に落下することも防止される。 Further, this crop harvesting machine has an engine 4 disposed at the rear part of the machine body, a mission case 5 disposed at the front side of the engine 4, and left and right frames 19 extending in a rearward raising posture toward the front of the machine body at the front part of the mission case 5. , 19 are fixed, the pulling and conveying device 15 is disposed above the frames 19, 19, and transmission members for transmitting the power for driving the traveling rotators 3, 3 are provided on the left and right sides of the transmission case 5. The left and right rear wheels 3 and 3 are mounted via transmission cases 7 and 7 extending below the bottom of the transmission case 5. Further, the foliage pedestal 17 is disposed above the left and right frames 19, 19. Thereby, the space which allows the base side part P1 which is cut | disconnected by the cutting device 16 and left in the kite U below the left and right frames 19 and 19 and the mission case 5 of the vehicle traveling across the kite U can pass to the rear of the model. The part S can be sufficiently secured at the bottom of the body. Therefore, although the airframe is configured compactly, the root side portion P1 that has landed on the ridge U is allowed to pass through the rear of the airframe without being largely defeated or dragged, and the cut leaf end side portion It is also possible to prevent P2 from falling on the root side portion P1.

本例の農作物収穫機は、引上げ搬送装置１５の挟持始端部に作物体Ｐの茎葉部ＰＬを掻集める茎葉掻集め装置３４を引上げ搬送装置１５の前側に設けている。この茎葉掻集め装置３４は、左右のフレーム１９，１９の各前端部に固着した左右の支持部材３５，３５にそれぞれ取付けた左右の支持フレーム３６，３６の前部と後部とに、それぞれ前側プーリー３７，３７と後側プーリー３８，３８とを軸着し、左右ぞれぞれの前側プーリー３７，３７と後側プーリー３８，３８とに、外周側に突出するラグ３９ａ…を多数有する掻集めベルト３９，３９を巻き掛け、更に、後側プーリー３８，３８の回転軸は、引上げ搬送装置１５の従動プーリー２１，２１と一体回転する回転軸２５，２５の上部に自在継ぎ手を介して連結して構成している。この茎葉掻集め装置３４は、左右の掻集めベルト３９，３９の前側が、左右外側に広がり且つ下位に位置するように傾斜した姿勢で配置している。これにより、掻集めベルト３９，３９は、左右に広がった作物体Ｐの茎葉部ＰＬを引上げ搬送装置１５の挟持始端部に向けて葉を持上げるようにしながら掻集めるように作用する。なお、畝Ｕの大きさや作物体Ｐの茎葉部の左右の広がりの程度に対応して、茎葉掻集め装置３４の左右の掻集めベルト３９，３９の各前部の左右位置及び上下高さを調節可能に設けている。更に、左右の掻集めベルト３９，３９の各前部の左右位置及び上下高さの調節に対応して左右傾斜角度も調節することで、茎葉部の掻き集め作用力が効果的に発揮されるようにも調節できる。また、掻集めベルト３９，３９の周回速度は、その機体後方の分速度が機体の前進速度と略同じ大きさから若干早い速度になるように設定して、掻集めベルト３９，３９が作物体Ｐを前方に押し倒さないようにしている。更にまた、本例では、左右の掻集めベルト３９，３９の各前端部から更に前方に延出するガイド棒４２，４２を設けているので、茎葉掻集め装置３４の大型化を押えつつ、茎葉部の掻集め範囲の拡大が図れる。具体的には、ガイド棒４２，４２は、左右の支持フレーム３６，３６の前部に取り付ける。そして、作業時には、ガイド棒４２，４２の前部が機体前側左右外側方に延びる位置に位置させ、機体の運搬時や格納時には、機体内側或は機体内側後方位置まで移動（例えば、ガイド棒の取付部を軸に回動）させて収納可能に構成することもできる。 In the crop harvesting machine of this example, a foliage collecting device 34 for collecting the foliage part PL of the crop body P is provided on the front side of the pulling and conveying device 15 at the clamping start end of the pulling and conveying device 15. The foliage collecting device 34 includes front pulleys on the front and rear portions of the left and right support frames 36 and 36 attached to the left and right support members 35 and 35 fixed to the front end portions of the left and right frames 19 and 19, respectively. 37 and 37 and the rear pulleys 38 and 38 are pivotally attached, and the left and right front pulleys 37 and 37 and the rear pulleys 38 and 38 have a large number of lugs 39a. The belts 39 and 39 are wound around, and the rotation shafts of the rear pulleys 38 and 38 are connected to the upper portions of the rotation shafts 25 and 25 that rotate integrally with the driven pulleys 21 and 21 of the pulling and conveying device 15 through a universal joint. Is configured. This foliage collecting device 34 is arranged in an inclined posture so that the front sides of the left and right collecting belts 39, 39 spread outward in the left and right sides and are located at the lower side. As a result, the scraping belts 39 and 39 act so as to scrape the stems and leaves PL of the crop body P spreading left and right while lifting the leaves toward the clamping start end of the pulling and conveying device 15. The left and right positions and the vertical heights of the front portions of the left and right scraping belts 39 and 39 of the foliage scraping device 34 corresponding to the size of the ridge U and the extent of the left and right spread of the foliage portion of the crop body P Adjustable. Further, by adjusting the right and left inclination angles corresponding to the adjustment of the left and right positions and the vertical heights of the front portions of the left and right collecting belts 39, 39, it is possible to effectively exert the action of collecting the foliage. Can also be adjusted. Further, the revolving speed of the scraping belts 39, 39 is set so that the rear speed of the airframe is slightly higher than the forward speed of the airframe, so that the scraping belts 39, 39 are the crop bodies. P is not pushed down. Furthermore, in this example, the guide rods 42, 42 extending further forward from the front end portions of the left and right scraping belts 39, 39 are provided, so that the foliage collecting device 34 can be prevented from being enlarged and the foliage can be suppressed. The collection range of the part can be expanded. Specifically, the guide bars 42 and 42 are attached to the front portions of the left and right support frames 36 and 36. During operation, the front portions of the guide rods 42 and 42 are positioned so as to extend to the left and right outer sides of the front side of the fuselage, and when transporting or storing the aircraft, they move to the inner side of the fuselage or the rear side of the fuselage (for example, the guide rod It can also be configured to be retractable by rotating the mounting portion about the shaft.

また、茎葉掻き集め装置３４を駆動する後側プーリー３８，３８は、引上げ搬送装置１５の従動プーリー２１，２１の上側に設けているので、作物体Ｐが生姜である場合に、引上げ搬送装置１５が茎葉部ＰＬを挟持するとき横側にのびて生育する生姜を割ってしまうことが生じにくくなる。すなわち、地中の生姜が左右に広がって生育していて複数本の茎葉部ＰＬが左右に幅広く並んで生育しているとき、引上げ搬送装置１５は左右に林立する複数の茎葉部ＰＬの中間部付近を左右中央側一箇所に集めて挟持することになるが、このとき、茎葉掻き集め装置を駆動する後側プーリーが引上げ搬送装置１５の従動プーリー２１，２１の下側に設けられていて該後側プーリーが大きく下方に突出していると、その突出部に左右両端側の茎葉部ＰＬが当たると左右に広がった生姜の左右両端部を左右内側に引っ張る状態となって、これにより左右に広がった生姜を大きく湾曲させて割ってしまうことがあり、或いはまた、後側プーリーの下側突出部との当たり箇所を通過して逆に左右両端側の茎葉部ＰＬが大きくたるみ、このため、左右に広がった生姜の左右端側が引上げ搬送装置１５で挟持された茎葉部で引っ張り上げられず、左右中央側箇所だけで引っ張り上げられる状態が生じ、このため左右に広がった生姜が前記とは逆に大きく湾曲して割れてしまうことがある。しかしながら、本例では、茎葉掻き集め装置３４を駆動する後側プーリー３８，３８は、引上げ搬送装置１５の従動プーリー２１，２１の上側に設けているので、このような問題を回避できる。 Further, since the rear pulleys 38, 38 for driving the foliage collecting device 34 are provided above the driven pulleys 21, 21 of the pulling and conveying device 15, when the crop body P is a ginger, the pulling and conveying device 15 When sandwiching the foliage part PL, it is difficult to break the ginger that grows laterally. That is, when the ginger in the ground grows to the left and right and a plurality of foliage parts PL grows side by side widely, the lifting and conveying device 15 is an intermediate part of the plurality of foliage parts PL that stands on the left and right. In this case, a rear pulley for driving the foliage collecting device is provided below the driven pulleys 21 and 21 of the pulling and conveying device 15 and is sandwiched between them. When the side pulley protrudes greatly downward, the left and right ends of the ginger that has spread to the left and right are pulled to the left and right when the left and right stems and leaves PL come into contact with the protruding portion. The ginger may be bent so as to be greatly curved, or, alternatively, the foliage PL on the left and right ends of the rear pulley passes through the contact point with the lower protrusion of the rear pulley, and the left and right ends of the stem and leaves are greatly slackened. The left and right ends of the spread ginger are not pulled up by the foliage sandwiched by the pulling and conveying device 15, but are pulled up only at the left and right center side. Therefore, the ginger spread to the left and right is larger than the above. It may be bent and cracked. However, in this example, since the rear pulleys 38 and 38 for driving the foliage collecting device 34 are provided on the upper side of the driven pulleys 21 and 21 of the pulling and conveying device 15, such a problem can be avoided.

また、茎葉掻き集め装置３４は、その掻き集め作用部（掻集めベルト３９，３９）の前部が走行回転体（前輪）２，２の前方を横切るように左右に広がっている構成としている。これにより、畝Ｕに生えている作物体Ｐの茎葉部が畝Ｕの左右側方の谷部まで左右に大きく広がっている場合でも、適確に引上げ搬送装置１５の挟持始端部Ａに掻き集められ、且つ、左右に広がった作物体Ｐの茎葉部を走行回転体（前輪）２，２を踏みつけて引上げ作業の妨げとならないようにすることができ、適確な引上げ作業が行えるようになる。 In addition, the foliage collecting device 34 has a configuration in which the front part of the collecting and collecting unit (the collecting belts 39 and 39) spreads left and right so as to cross the front of the traveling rotating bodies (front wheels) 2 and 2. As a result, even when the foliage of the crop body P growing on the cocoon U is widened to the left and right to the troughs on the left and right sides of the cocoon U, the crop body P is properly raked up at the clamping start end A of the pulling and conveying device 15. In addition, it is possible to prevent the pulling work from being hindered by stepping on the rotating rotating bodies (front wheels) 2 and 2 of the foliage of the crop body P spreading to the left and right, so that an accurate pulling work can be performed.

ところで、案内体４３，４３を図４に示すように、引上げ搬送装置１５の後部上で機体平面視で引上げベルト１４，１４の周回内側に位置する個所に取付けて、案内体４３，４３が、機体平面視で引上げ搬送装置１５の引上げベルト１４，１４の周回内側から周回外側後方に延び、更に、左右外側方に延びる状態となるよう設けることで、案内体４３，４３が引上げ搬送装置１５から排出される茎葉部を機体側方に案内するとともに、引上げベルト１４，１４に貼り付いて連れ回りする茎葉部を阻止する作用も生じ、茎葉部の排出を適確に行えるものとなる。なお、図例のように、左右の引上げベルト１４，１４の各周回内側から周回外側に案内体４３，４３を左右それぞれ延出させると一層効果が顕著になり、また、引上げベルト１４，１４の周回内側から引上げベルトの上側と下側の上下両方から引上げベルト１４，１４の周回内側から周回外側に案内体４３，４３を上下それぞれ延出させると一層効果が顕著になる。なお、案内体４３，４３，４３，４３の具体的な取付けは、支持部材２６に取り付ける構成とする。 By the way, as shown in FIG. 4, the guide bodies 43, 43 are mounted on the rear portion of the pulling and conveying device 15 at a position located inside the circumference of the pulling belts 14, 14 in plan view of the machine body. The guide bodies 43, 43 are arranged so as to extend from the inner side of the pulling belts 14, 14 of the pulling and conveying device 15 to the rear outer side of the pulling and conveying device 15 in a plan view of the machine body and further to the left and right outer sides. In addition to guiding the discharged foliage side to the side of the machine body, there is also an effect of blocking the foliage that sticks to the pulling belts 14 and 14 and rotates, so that the foliage can be discharged properly. It should be noted that, as shown in the figure, if the guide bodies 43, 43 are extended from the inner side to the outer side of the left and right pulling belts 14, 14, respectively, the effect becomes more significant. When the guide bodies 43 and 43 are extended from the inner side of the pulling belt from the upper and lower sides of the pulling belt to the outer side of the pulling belts 14 and 14, respectively, the effect becomes more remarkable. The guides 43, 43, 43, 43 are specifically attached to the support member 26.

更に、図５に示すように、引上げ搬送装置１５の挟持終端部Ｃの左右両側方に案内体４４，４４を設け、各案内体４４，４４は、それぞれ機体後方に延び、続いて左右外側方に延びるように設け、更に、中央案内体４５を、左右一方側の案内体４４に沿うように延びるように設け、該中央案内体４５の取付個所と取付姿勢を変更することで、右側の案内体４４に沿って延びる状態と左側の案内体４４に沿って延びる状態とに変更可能に設けることもできる。こうすると、茎葉部の排出方向を左右切換えが可能となり、圃場条件等に応じて選択できる作業行路の自由度が拡大でき、作業性が向上する。なお、案内体４４，４４の具体的な取付けは、支持部材２６に取り付ける構成とする。 Further, as shown in FIG. 5, guide bodies 44, 44 are provided on both the left and right sides of the clamping terminal portion C of the pulling and conveying apparatus 15, and each guide body 44, 44 extends to the rear of the machine body, and subsequently laterally outward. Further, the central guide body 45 is provided so as to extend along the guide body 44 on one of the left and right sides, and the right guide is changed by changing the mounting location and the mounting posture of the central guide body 45. It can also be provided so as to be changeable between a state extending along the body 44 and a state extending along the left guide body 44. If it carries out like this, the discharge direction of a foliage part can be changed to right and left, the freedom degree of the work course which can be chosen according to field conditions etc. can be expanded, and workability will improve. The guide members 44 and 44 are specifically attached to the support member 26.

図６に示す構成は、引上げ搬送装置１５の左右の引上げベルト１４’，１４’の後部位置を前後にずらした構成である。このようにすると、左右の引上げベルト１４’，１４’が互いに接当する部分が終わる個所から後方に挟持されていた茎葉部が排出され、更に、そこから後方に延びる左右一方側の引上げベルト１４’にて後方に案内されつつ、左右他方側においては引上げベルト１４’がないためにその側に茎葉部が放出されるようになって、機体の一側方へ茎葉部を案内する上記のような案内体なしに茎葉部を機体の一側方に排出できるようになり、機体構成の簡略化が図れる。図中の符号２０’，２０’は、左右の引上げ搬送ベルト１４’，１４’を駆動回転する駆動プーリーを示し、図示省略しているが、左右の引上げ搬送ベルト１４’，１４’は、この駆動プーリー２０’，２０’と前側に設けた従動プーリーと、引上げ搬送ベルト１４’，１４’の内側から支持する複数のローラーとの周りに巻き掛けられて周回動する構成となっている。 The configuration shown in FIG. 6 is a configuration in which the rear positions of the left and right pulling belts 14 ′, 14 ′ of the pulling and conveying device 15 are shifted back and forth. In this way, the foliage held between the left and right pulling belts 14 'and 14' ends from the end, and the left and right pulling belts 14 extending rearward therefrom are further discharged. As described above for guiding the foliage part to one side of the aircraft, since the foliage part is released on that side because there is no pulling belt 14 'on the other side, while being guided rearward The stems and leaves can be discharged to one side of the aircraft without a guide, and the configuration of the aircraft can be simplified. Reference numerals 20 ′ and 20 ′ in the figure indicate drive pulleys that drive and rotate the left and right pulling conveyor belts 14 ′ and 14 ′, which are not shown, but the left and right pulling conveyor belts 14 ′ and 14 ′ The driving pulleys 20 ′ and 20 ′, a driven pulley provided on the front side, and a plurality of rollers supported from the inside of the pulling and conveying belts 14 ′ and 14 ′ are wound around and rotated.

図７に示す構成は、引上げ搬送装置１５の後側に排出された茎葉部を機体の左右外側方に移送させる移送手段４５と、該移送手段４５によって移送されてきた茎葉部を後輪３の前方に落下させるシュータ４６を設けた構成である。従った、作物体Ｐから切断された葉先側部分Ｐ２の茎葉部を後輪３が踏みつけていくものとなり、機体側方で葉先側部分Ｐ２の茎葉部が滞留することが生じにくくなり、能率良く作業が行えるものとなる。なお、移送手段４５は、図７に示すような棒材で構成した案内体によって案内するものでもよく、駆動回転する左右一対の挟持搬送ベルトによって移送するものでもよい。 The configuration shown in FIG. 7 includes a transfer means 45 for transferring the foliage discharged to the rear side of the pulling and conveying device 15 to the left and right outer sides of the machine body, and the foliage transferred by the transfer means 45 on the rear wheel 3. The shooter 46 is provided to drop forward. Accordingly, the rear wheel 3 will step on the foliage portion of the leaf tip side portion P2 cut from the crop body P, and the foliage portion of the leaf tip side portion P2 is less likely to stay on the side of the machine body, It will be possible to work efficiently. The transfer means 45 may be guided by a guide body made of a bar as shown in FIG. 7 or may be transferred by a pair of left and right nipping and conveying belts that are driven and rotated.

なお、引上げ搬送装置１５の前側の従動プーリ２１，２１を左右外方に移動可能に設けて、引上げ搬送装置１５の挟持始端部Ａより前側で平面視Ｖ字状に広がる左右の引上げ搬送ベルト１４，１４間の隙間を左右に拡大可能に構成したものである。これにより、畝Ｕ上に作物体Ｐが二列で植生している場合でも一対の引上げ搬送ベルト１４，１４で適確に挟持して引上げ作業が行えるようになる。 Note that the front driven pulleys 21 and 21 on the front side of the pulling and conveying apparatus 15 are provided so as to be movable left and right, and the left and right pulling and conveying belts 14 spread in a V shape in plan view on the front side from the clamping start end A of the pulling and conveying apparatus 15. , 14 is configured such that the gap between them can be expanded to the left and right. As a result, even when the crop bodies P are vegetated in two rows on the ridge U, the pulling operation can be performed by properly holding the pair of pulling conveyance belts 14 and 14.
