Description

本発明は、圃場から作物を採ってフレコンバッグ等の収容部材に収容する根菜類収穫機に関するものである。 The present invention relates to a root vegetable harvester that collects crops from a field and stores them in a storage member such as a flexi-con bag.

従来、引抜搬送装置で圃場から根菜類を引抜き搬送し、選別搬送装置の搬送終端部に設けたフレコンバッグで根菜類を収容する根菜類収穫機がある。（たとえば、特許文献１参照）。 Conventionally, there is a root vegetable harvester that extracts and transports root vegetables from a field using a pulling and transporting device, and stores the root vegetables in a flexible container bag provided at the end of the transport path of a sorting and transporting device (see, for example, Patent Document 1).

特開２０１１－１１５０６９号公報JP 2011-115069 A

しかしながら、根菜類が満杯になったフレコンバッグを機体後方に向けて圃場に降ろすので、機体を旋回させて隣接条の作物を収穫する際に圃場に降ろされたフレコンバッグが進行する機体のすぐ側方にあり、フレコンバッグが傾いたり機体が少し蛇行したりすると、機体にフレコンバッグが接触してフレコンバッグが破れて根菜類が圃場に散乱して適正な収穫作業が行なえなくなるような事態が発生する恐れがある。 However, because the FIBC bags filled with root vegetables are lowered into the field toward the rear of the machine, when the machine is rotated to harvest the crops in the adjacent row, the FIBC bags lowered into the field are located right to the side of the moving machine. If the FIBC bags tilt or the machine meanders slightly, there is a risk that the FIBC bags may come into contact with the machine and break, causing the root vegetables to scatter across the field and making it impossible to carry out proper harvesting work.

本発明は、上記に鑑みてなされたものであって、圃場に降ろしたフレコンバッグ等の収容部材に機体が接触することを回避した根菜類収穫機を提供することを目的とする。 The present invention has been made in consideration of the above, and aims to provide a root vegetable harvester that prevents the machine body from coming into contact with storage members such as flexi-con bags that are lowered into the field.

The left and right driving sprockets 2, 2 of the left and right crawlers 6L, 6R are attached to left and right drive shafts extending to both the left and right sides from a transmission case to which the engine power is transmitted, and the left and right crawlers 6L, 6R are attached to the machine body frame 1 with a certain left-right gap between them.

＜操縦部Ｂ＞
前記機体フレーム１の右側上部に操縦部フレーム７を取り付け、該操縦部フレーム７には操縦座席８を取り付けると共に、機体前側に操縦パネル９を取り付ける。そして、該操縦パネル９に機体の前後進及び走行速度を切り換える変速操作レバー１０を取り付けると共に、機体の左右旋回操作及び収穫部Ｃの作業高さを操作する昇降操作レバー１１を取り付ける。 <Control Unit B>
A control frame 7 is attached to the upper right side of the machine frame 1, and a control seat 8 is attached to the control frame 7, and a control panel 9 is attached to the front of the machine. A speed change lever 10 for switching between forward and reverse movement and the traveling speed of the machine is attached to the control panel 9, and a lift control lever 11 for turning the machine left and right and for controlling the working height of the harvesting section C is also attached.

また、前記操縦部フレーム７の機体左右他側（機体右側）にエンジンを冷却するラジエータ（図示省略）を保護すると共に冷却風を取り込むラジエータカバー１２を着脱自在に取り付けることにより。操縦部Ｂが構成される。 The control section B is formed by attaching a radiator cover 12, which protects the radiator (not shown) that cools the engine and takes in cooling air, to the other left or right side of the control section frame 7 (right side of the aircraft).

上記構成により、変速操作レバー１０や昇降操作レバー１１のような、１本で複数の操作を行える操縦部材を設けることによって、機体の操縦が容易になるため操縦者の作業を軽減することができる。 The above configuration allows for the provision of control members such as the gear shift control lever 10 and the lift control lever 11 that can perform multiple operations with a single lever, making it easier to control the aircraft and reducing the workload of the pilot.

＜収穫部Ｃ＞
左右引抜フレーム１３，１３の機体前側に左右従動プーリ１４ａ，１４ａを回転自在に装着し、機体後側に左右駆動プーリ１４ｂ，１４ｂを装着し、該左右従動プーリ１４ａ，１４ａと左右駆動プーリ１４ｂ，１４ｂとの間に人参を引き抜き機体後部へと搬送する左右挟持搬送ベルト１５，１５を巻き掛けると共に、複数のテンションローラ１６によって該左右挟持搬送ベルト１５，１５を張圧し、左右挟持搬送ベルト１５，１５の機体内側面を互いに圧接させて人参の引抜搬送経路（引抜搬送通路）Ｒを構成する。そして、前記機体フレーム１の上方に左右横軸を回動支点として上下方向に回動自在な回動フレームを取り付け、該回動フレームの後端部に前記左右駆動プーリ１４ｂ，１４ｂに駆動力を伝動する伝動ケースを、回動支点を中心として上下回動自在に取り付ける。また、前記機体フレーム１と回動フレームとを昇降シリンダで連結し、該昇降シリンダを操縦部Ｂで操作可能に取り付けて引抜搬送装置１７を構成する。 <Harvesting Section C>
Left and right driven pulleys 14a, 14a are rotatably attached to the front sides of the left and right pulling-out frames 13, 13, left and right driving pulleys 14b, 14b are attached to the rear sides of the machine, left and right clamping conveyor belts 15, 15 for pulling carrots and transporting them to the rear of the machine are wound between the left and right driven pulleys 14a, 14a and the left and right driving pulleys 14b, 14b, and the left and right clamping conveyor belts 15, 15 are tensioned by a plurality of tension rollers 16 so that the inside surfaces of the left and right clamping conveyor belts 15, 15 are pressed against each other to form a carrot pulling-out conveyor path (pulling-out conveyor passage) R. A rotating frame is attached above the machine frame 1 so as to be vertically rotatable about left and right horizontal axes as rotation fulcrums, and a transmission case for transmitting driving force to the left and right driving pulleys 14b, 14b is attached to the rear end of the rotating frame so as to be vertically rotatable about the rotation fulcrum. The machine frame 1 and the rotary frame are connected by a lifting cylinder, and the lifting cylinder is attached so as to be operable by the control section B to constitute a drawing and conveying device 17.

また、該引抜搬送装置１７の前方に人参の茎葉部を引き起こす縦引起し装置１８と、該縦引起し装置１８が引起した茎葉部を掬い上げる横引起し装置１９と、該横引起し装置１９の前部に設ける分草杆２０と、引抜搬送装置１７の下り過ぎを防止する回転自在なゲージ輪と、前記エンジンの駆動力で往復振動して土中の人参の左右の土を解す左右振動ソイラＳとを設ける。 In addition, a vertical lifting device 18 that lifts the stems and leaves of carrots is provided in front of the pulling and conveying device 17, a horizontal lifting device 19 that scoops up the stems and leaves lifted by the vertical lifting device 18, a grass-splitting rod 20 provided in front of the horizontal lifting device 19, a rotatable gauge wheel that prevents the pulling and conveying device 17 from descending too far, and a left-right vibrating soiler S that vibrates back and forth with the driving force of the engine to loosen the soil on the left and right of the carrots buried in the soil.

そして、前記引抜搬送通路Ｒの下方に引抜搬送装置１７で搬送中の人参のひげ根を切断する尻尾切装置を取り付けて、収穫部Ｃを構成する。 A tail cutting device that cuts off the roots of carrots being transported by the pulling and conveying device 17 is installed below the pulling and conveying passage R, forming the harvesting section C.

上記構成により、機体前側に分草杆２０を備える横引起し装置１９と、縦引起し装置１８を設けることによって、圃場に倒伏した人参の茎葉を掻き上げながら収穫作業ができ、収穫する人参の視認性が向上するので引き抜き位置が合わせやすく、作物の抜き残しが減少するため作業能率が向上する。 With the above configuration, by providing a horizontal pulling device 19 with a grass-dividing rod 20 on the front side of the machine body and a vertical pulling device 18, harvesting work can be done while raking up the stems and leaves of carrots that have fallen in the field. Since the visibility of the carrots to be harvested is improved, it is easier to align the pulling position, and the amount of crop left behind is reduced, improving work efficiency.

また、人参に左右振動ソイラＳ等が接触して傷つくことを防止できるので、人参の商品価値が向上する。 In addition, it prevents the carrots from being damaged by contact with the left-right vibrating soy grinder S, etc., improving the commercial value of the carrots.

そして、機体フレーム１と左右横軸を回動支点として上下方向に回動自在な回動フレームとを昇降シリンダで連結し、昇降シリンダを操縦部Ｂの昇降操作レバー１１を操作することによって伸縮させる構成としたことによって、昇降操作レバー１１の操作により収穫部Ｃ全体の上下高さを調節することができるので、収穫部Ｃの引抜搬送始端部の位置を上下方向に調節しするとともに圃場に植生する人参の適切な引き抜き高さに合わせて引抜搬送始端部の位置調節を行え、人参の抜き残しが防止されるので作業能率が向上する。 The machine frame 1 and a rotating frame that can rotate up and down around the left and right horizontal axes are connected by a lifting cylinder, and the lifting cylinder is extended and retracted by operating the lifting lever 11 on the steering unit B. This allows the vertical height of the entire harvesting unit C to be adjusted by operating the lifting lever 11, so that the position of the starting end of the harvesting unit C for pulling out can be adjusted up and down, and the position of the starting end of the pulling out can be adjusted to match the appropriate pulling height of the carrots growing in the field, preventing any carrots from being left behind and improving work efficiency.

また、旋回時に収穫部Ｃを上昇させておくと、収穫部Ｃの下端部が圃場に接触しにくくなるため、旋回動作がスムーズに行われて作業能率が向上する。 In addition, if the harvesting section C is raised when turning, the lower end of the harvesting section C is less likely to come into contact with the field, making the turning operation smoother and improving work efficiency.

＜選別搬送部Ｄ＞
選別搬送部Ｄの選別作業用の選別搬送装置２１は、収穫部Ｃの引抜搬送装置１７の後部下方から人参を収容する収容部材であるフレコンバッグ２２のある収容部Ｅに向けて機体左右方向に配置され、エンジンからの駆動力にて周回動する一定間隔の桟を備えるチェーンコンベアにて構成されている。なお、引抜搬送装置１７にて茎葉部が挟持されて搬送してきた人参は、その茎葉部下端（人参の頭部の少し上）が茎葉切断部にて切断されて人参が下方に落下するが、該落下する人参を残葉処理部が受けて人参に残った茎葉部を処理して選別搬送部Ｄに搬送する。そして、選別搬送部Ｄの選別搬送装置２１は、人参をその左端から右方（収容部Ｅ）に搬送する。 <Sorting and conveying section D>
The sorting and conveying device 21 for sorting work in the sorting and conveying section D is arranged in the left-right direction of the machine body from the rear lower part of the pulling and conveying device 17 in the harvesting section C toward the storage section E where the flexi-con bags 22, which are storage members for storing carrots, are located, and is composed of a chain conveyor with bars at regular intervals that rotates by the driving force from the engine. The carrots conveyed by the pulling and conveying device 17 with their stems and leaves clamped are cut at the stem and leaf cutting section at their lower ends (slightly above the heads of the carrots) and the carrots fall downward, but the remaining leaf processing section receives the fallen carrots and processes the stems and leaves remaining on the carrots before conveying them to the sorting and conveying section D. The sorting and conveying device 21 in the sorting and conveying section D conveys the carrots from their left ends to the right (storage section E).

また、選別搬送装置２１は、収穫部Ｃの引抜搬送装置１７の後部下方から機体右側に水平に設けられた水平搬送コンベア２１ａと該水平搬送コンベア２１ａ右端部から収穫作物を引き継いで収容部Ｅに斜め右上方に向けて搬送する可動搬送コンベア２１ｂから構成される。 The sorting and conveying device 21 is also composed of a horizontal conveying conveyor 21a that is installed horizontally on the right side of the machine body from the rear lower part of the extraction and conveying device 17 in the harvesting section C, and a movable conveying conveyor 21b that takes over the harvested crops from the right end of the horizontal conveying conveyor 21a and conveys them diagonally upward and to the upper right to the storage section E.

可動搬送コンベア２１ｂは、水平搬送コンベア２１ａ右端部から収穫作物を引き継ぐ左端部が枢支軸で回動自在に支持されており、上下動用電動シリンダ２１ｃの伸縮作動により収容部Ｅ側の右端部側が上下動して傾斜角度が変更できるようになっている。 The movable transport conveyor 21b has its left end, which takes over the harvested crops from the right end of the horizontal transport conveyor 21a, supported by a pivot shaft so that it can rotate freely. The right end side on the storage section E side moves up and down by the extension and contraction of the vertical movement electric cylinder 21c, allowing the inclination angle to be changed.

そして、該可動搬送コンベア２１ｂの機体後方側に補助作業座席２３が設けられており、該補助作業座席２３に着座した作業者が可動搬送コンベア２１ｂにて送られてくる人参のなかから商品にならないもの（小さい人参や異形の人参）を取り出して、適正な商品価値のある人参のみを収容部Ｅに送るようにする。 An auxiliary work seat 23 is provided on the rear side of the movable transport conveyor 21b, and a worker seated on the auxiliary work seat 23 removes non-marketable carrots (small carrots or carrots with irregular shapes) from the carrots sent by the movable transport conveyor 21b, and sends only carrots with appropriate market value to the storage section E.

また、補助作業座席２３に着座した作業者は、足踏み式の上昇スイッチ及び加工スイッチにて前記上下動用電動シリンダ２１ｃを伸縮作動させて可動搬送コンベア２１ｂの右端部側を上下動させる。 The worker seated on the auxiliary work seat 23 can use the foot-operated lift switch and processing switch to extend and retract the vertical movement electric cylinder 21c, thereby moving the right end of the movable transport conveyor 21b up and down.

＜収容部Ｅ＞
収容部Ｅは、選別搬送装置２１の右側方に配置され、該選別搬送装置２１の可動搬送コンベア２１ｂ右端部に設けた作動アーム２４により上下動及び左右動する吊り下げハンガー２５と、該吊り下げハンガー２５に吊り下げられたフレコンバッグ２２を載置する載置台２６により構成されている。 <Storage section E>
The storage section E is located to the right of the sorting and conveying device 21, and is composed of a hanging hanger 25 that moves up and down and left and right by an operating arm 24 provided at the right end of the movable conveying conveyor 21b of the sorting and conveying device 21, and a loading platform 26 on which the flexi-con bag 22 hung from the hanging hanger 25 is placed.

可動搬送コンベア２１ｂは、左端基部から右端上部に向けて斜め上方に向かって設けられている。即ち、エンジンからの駆動力にて周回動して人参を斜め上方に搬送し、上端部から下方に放出する。また、可動搬送コンベア２１ｂの基部は、枢支軸にて回動自在に設けられており、中途部には、機体フレーム１に基部が枢支された上下動用電動シリンダ２１ｃのピストン先端が連結されている。 The movable transport conveyor 21b is installed diagonally upward from the base at the left end to the upper right end. That is, it rotates with the driving force from the engine to transport the carrots diagonally upward and release them downward from the upper end. The base of the movable transport conveyor 21b is installed so that it can rotate freely on a pivot shaft, and the piston tip of the vertical movement electric cylinder 21c, whose base is pivoted to the machine frame 1, is connected to the middle part.

即ち、該可動搬送コンベア２１ｂは、補助作業座席２３に着座した作業者が踏み操作する上昇スイッチを踏み込み操作している間、上下動用電動シリンダ２１ｃが伸長して枢支軸回りに回動して上昇し、下降スイッチを踏み込み操作している間、上下動用電動シリンダ２１ｃが縮小して枢支軸回りに回動して下降する。また、可動搬送コンベア２１ｂは、後述の操縦パネル９右端に設けた十字方向操作レバー２７を作業者が圃場に降りて機体後方を向いた状態で右に操作すると上下動用電動シリンダ２１ｃが伸長して枢支軸回りに回動して上昇し、左に操作すると上下動用電動シリンダ２１ｃが縮小して枢支軸回りに回動して下降する。 That is, while the operator seated on the auxiliary work seat 23 presses on the up switch, the vertical movement electric cylinder 21c extends and rotates around the pivot shaft to rise, and while the operator presses on the down switch, the vertical movement electric cylinder 21c contracts and rotates around the pivot shaft to fall. Also, when the operator descends into the field and operates the cross-directional operation lever 27 provided on the right end of the operation panel 9 (described later) to the right while facing the rear of the machine, the vertical movement electric cylinder 21c extends and rotates around the pivot shaft to rise, and when the operator operates it to the left, the vertical movement electric cylinder 21c contracts and rotates around the pivot shaft to fall.

吊り下げハンガー２５は、可動搬送コンベア２１ｂ右端部に設けた作動アーム２４により上下動及び左右動する。 The hanging hanger 25 moves up and down and left and right by the operating arm 24 attached to the right end of the movable transport conveyor 21b.

作動アーム２４は、基部が可動搬送コンベア２１ｂ右端部に背面視で反時計方向には回動するが時計方向には所定位置で回動が停止するように枢支され、先端側が機体右外側上方に向けて延設されている基部アーム２４ａと、該基部アーム２４ａ先端に回動自在に枢支された回動アーム２４ｂと、基部アーム２４ａと回動アーム２４ｂ間に配設された回動用アクチュエータとしての回動用電動シリンダ２４ｃから構成される。 The operating arm 24 is composed of a base arm 24a whose base is pivoted to the right end of the movable transport conveyor 21b so that it can rotate counterclockwise when viewed from behind, but stops rotating clockwise at a predetermined position, and whose tip is extended toward the upper right outside of the machine body, a rotating arm 24b pivoted to the tip of the base arm 24a so that it can rotate freely, and a rotating electric cylinder 24c that serves as a rotating actuator and is disposed between the base arm 24a and the rotating arm 24b.

吊り下げハンガー２５は、回動アーム２４ｂの先端に設けられている。載置台２６上方で、吊り下げハンガー２５の４つのフック２５ａをフレコンバッグ２２の上端縁部の係止孔に各々引っ掛けてフレコンバッグ２２を吊下げ支持する。 The hanging hanger 25 is attached to the tip of the rotating arm 24b. Above the mounting table 26, the four hooks 25a of the hanging hanger 25 are hooked onto the locking holes in the upper edge of the FIBC bag 22 to support the FIBC bag 22 in a suspended state.

操縦パネル９右端には、十字方向操作レバー２７が設けられており、作業者が圃場に降りて機体後方を向いた状態で右に操作すると上下動用電動シリンダ２１ｃが伸長して可動搬送コンベア２１ｂが枢支軸回りに回動して上昇し、左に操作すると上下動用電動シリンダ２１ｃが縮小して可動搬送コンベア２１ｂが枢支軸回りに回動して下降し、機体後方に操作すると回動用電動シリンダ２４ｃが伸長して回動アーム２４ｂが枢支軸回りに回動して右外側方に開き、機体前方に操作すると回動用電動シリンダ２４ｃが縮小して回動アーム２４ｂが枢支軸回りに回動して左機体内側に閉じる。 A cross-directional operation lever 27 is provided at the right end of the operation panel 9. When the operator descends into the field and faces the rear of the machine, operating it to the right will extend the vertical movement electric cylinder 21c and cause the movable transport conveyor 21b to rotate around the pivot shaft and rise; operating it to the left will cause the vertical movement electric cylinder 21c to contract and cause the movable transport conveyor 21b to rotate around the pivot shaft and lower; operating it towards the rear of the machine will cause the pivoting electric cylinder 24c to extend and cause the pivoting arm 24b to rotate around the pivot shaft and open outward to the right; operating it towards the front of the machine will cause the pivoting electric cylinder 24c to contract and cause the pivoting arm 24b to rotate around the pivot shaft and close inside the machine to the left.

この十字方向操作レバー２７の操作時に、可動搬送コンベア２１ｂが最上昇位置にないと十字方向操作レバー２７を機体後方に操作しても回動用電動シリンダ２４ｃは作動せず回動アーム２４ｂが枢支軸回りに回動して右外側方に開くことはない。即ち、可動搬送コンベア２１ｂが最上昇位置にある時のみ、十字方向操作レバー２７を機体後方に操作して回動用電動シリンダ２４ｃを作動させて回動アーム２４ｂを枢支軸回りに回動して右外側方に開くことができる。 When operating this cross-directional operation lever 27, if the movable transport conveyor 21b is not in the uppermost position, even if the cross-directional operation lever 27 is operated toward the rear of the machine, the electric rotating cylinder 24c will not operate and the rotating arm 24b will not rotate around the pivot shaft to open to the right outside. In other words, only when the movable transport conveyor 21b is in the uppermost position can the cross-directional operation lever 27 be operated toward the rear of the machine to operate the electric rotating cylinder 24c and rotate the rotating arm 24b around the pivot shaft to open to the right outside.

また、載置台２６には荷重センサ２８が設けられており、吊り下げハンガー２５に吊るされたフレコンバッグ２２が持ち上げられてフレコンバッグ２２の底が載置台２６から離れた時のみ（荷重センサ２８がフレコンバッグ２２を検出しなくなった時のみ）、十字方向操作レバー２７を機体後方に操作して回動用電動シリンダ２４ｃを作動させて回動アーム２４ｂを枢支軸回りに回動して右外側方に開くことができる。 A load sensor 28 is also provided on the platform 26, and only when the FIBC bag 22 suspended from the hanging hanger 25 is lifted and the bottom of the FIBC bag 22 separates from the platform 26 (only when the load sensor 28 no longer detects the FIBC bag 22), the cross-directional control lever 27 is operated toward the rear of the machine to activate the rotating electric cylinder 24c, causing the rotating arm 24b to rotate around the pivot shaft and open outward to the right.

また、載置台２６右外側端には上方に物体があることを検出するフォトセンサ２９が設けられており、吊り下げハンガー２５に吊るされたフレコンバッグ２２が持ち上げられて回動用電動シリンダ２４ｃの作動により回動アーム２４ｂが枢支軸回りに回動して右外側方に開いて機体右外側方に移動した時に、フレコンバッグ２２が載置台２６右外側端上方にないこと（フレコンバッグ２２が載置台２６右外側端よりも右外側方に移動したこと）を検出しないと、十字方向操作レバー２７を左に操作して可動搬送コンベア２１ｂを枢支軸回りに回動して下降させようとしても、上下動用電動シリンダ２１ｃは作動せず、可動搬送コンベア２１ｂは下動しない。よって、吊り下げハンガー２５に吊るされたフレコンバッグ２２を圃場に降ろす際に、誤ってフレコンバッグ２２が載置台２６右外側端に接触することを回避できる。 In addition, a photosensor 29 is provided at the right outer end of the loading platform 26 to detect the presence of an object above. When the FIBC bag 22 suspended from the hanging hanger 25 is lifted and the rotating arm 24b rotates about the pivot shaft by the operation of the rotating electric cylinder 24c to open to the right outer side and move to the right outer side of the machine body, if it is not detected that the FIBC bag 22 is not above the right outer end of the loading platform 26 (the FIBC bag 22 has moved to the right outer side beyond the right outer end of the loading platform 26), even if the cross-directional operation lever 27 is operated to the left to rotate the movable transport conveyor 21b about the pivot shaft and lower it, the vertical movement electric cylinder 21c will not operate and the movable transport conveyor 21b will not move downward. Therefore, when the FIBC bag 22 suspended from the hanging hanger 25 is lowered into the field, it is possible to avoid the FIBC bag 22 accidentally coming into contact with the right outer end of the loading platform 26.

＜人参の収穫作業＞
先ず、図４に示すように、十字方向操作レバー２７を操作して、回動アーム２４ｂが左機体内側に閉じた状態で可動搬送コンベア２１ｂを最下降位置にする。 <Carrot harvesting work>
First, as shown in FIG. 4, the cross-directional operating lever 27 is operated to move the movable transfer conveyor 21b to its lowest position with the rotating arm 24b closed toward the inside of the left machine body.

吊り下げハンガー２５の各フック２５ａにフレコンバッグ２２の上端縁部の係止孔を各々引っ掛けてフレコンバッグ２２を吊下げ、フレコンバッグ２２の底が載置台２６に受けられた状態とする。 The FIBC bag 22 is suspended by hooking the hooks 25a of the hanging hanger 25 to the locking holes at the upper edge of the FIBC bag 22, so that the bottom of the FIBC bag 22 is supported on the mounting table 26.

そして、操縦座席８に着座した操縦者が人参収穫機を進行させて、収穫部Ｃの引抜搬送装置１７の引抜搬送経路Ｒ前端を圃場の人参条に合わせた後に昇降操作レバー１１を操作して収穫部Ｃを下降させ、掘取りクラッチを「入」にして各部を駆動させて前進する。すると、分草杆２０や縦引起し装置１８や横引起し装置１９にて人参の茎葉を掻き上げて引抜搬送装置１７の引抜搬送経路Ｒに人参の茎葉が挟持され、左右振動ソイラＳにて人参の側方及び下方の土をほぐして、人参は引抜搬送装置１７にて挟持されて引き抜かれて、後方上方に搬送される。 Then, the operator seated in the driver's seat 8 advances the carrot harvester, aligning the front end of the extraction transport path R of the extraction transport device 17 of the harvesting section C with the carrot rows in the field, then operates the lifting operation lever 11 to lower the harvesting section C, and turns on the digging clutch to drive each section and move forward. Then, the weeding rod 20, vertical lifting device 18, and horizontal lifting device 19 rake up the carrot stems and leaves, clamping them on the extraction transport path R of the extraction transport device 17, and the left and right vibrating soiler S loosens the soil to the sides and below the carrots, and the carrots are clamped and pulled out by the extraction transport device 17 and transported upward and rearward.

そして、引抜搬送装置１７にて茎葉部が挟持されて搬送してきた人参は、その茎葉部下端（人参の頭部の少し上）が茎葉切断部にて切断されて人参が下方に落下するが、該落下する人参は残葉処理部が受けて人参に残った茎葉部を処理して選別搬送部Ｄに搬送される。そして、人参は、選別搬送部Ｄの可動搬送コンベア２１ｂにてその左端から右方（収容部Ｅ）に搬送される。 Then, the carrots that have been conveyed by the pulling and conveying device 17 with their stems and leaves clamped are cut at the stem and leaf cutting section at their lower ends (slightly above the top of the carrot) and the carrots fall downward. The carrots that fall are received by the remaining leaf processing section, which processes the remaining stems and leaves on the carrots and conveys them to the sorting and conveying section D. The carrots are then conveyed from their left end to the right (storage section E) by the movable conveyor 21b of the sorting and conveying section D.

そして、可動搬送コンベア２１ｂの機体後方側の補助作業座席２３に着座した作業者が可動搬送コンベア２１ｂにて送られてくる人参のなかから商品にならないもの（小さい人参や異形の人参）を取り出し、商品価値のある人参のみが収容部Ｅに送られる。 Then, a worker seated on the auxiliary work seat 23 at the rear of the movable transport conveyor 21b removes non-marketable carrots (small carrots or carrots with irregular shapes) from the carrots being transported by the movable transport conveyor 21b, and only the carrots with marketable value are sent to the storage section E.

可動搬送コンベア２１ｂにて右端に送られてきた人参は、可動搬送コンベア２１ｂ右端の吊り下げハンガー２５の各フック２５ａに吊下げられたフレコンバッグ２２内に落下して収納される。 The carrots sent to the right end by the movable transport conveyor 21b drop into and are stored in the flexible container bags 22 hung from the hooks 25a of the hanging hangers 25 at the right end of the movable transport conveyor 21b.

そして、フレコンバッグ２２内に収納された人参の量が多くなるにつれて、補助作業座席２３に着座した作業者が上昇スイッチを踏み込み操作して上下動用電動シリンダ２１ｃを伸長させて可動搬送コンベア２１ｂを枢支軸回りに回動して順次上昇させる。 As the amount of carrots stored in the flexi-con bag 22 increases, the worker seated on the auxiliary work seat 23 presses the lift switch to extend the vertical movement electric cylinder 21c, causing the movable transport conveyor 21b to rotate around the pivot shaft and gradually rise.

そして、図５に示すように、フレコンバッグ２２内に人参が満杯になるまで可動搬送コンベア２１ｂを枢支軸回りに回動して上昇させると、操縦者は機体の駆動を停止して停車する。 Then, as shown in FIG. 5, the movable transport conveyor 21b is rotated about the pivot shaft and raised until the flexi-con bag 22 is filled with carrots, and then the operator stops driving the machine and stops it.

補助作業座席２３に着座した作業者は、補助作業座席２３から離れて圃場に降りて操縦パネル９右端近くに立って、機体後方を向いた状態で十字方向操作レバー２７を操作する。 The operator seated in the auxiliary work seat 23 leaves the auxiliary work seat 23, descends to the field, stands near the right end of the control panel 9, and operates the cross-directional control lever 27 while facing toward the rear of the machine.

先ず、十字方向操作レバー２７を右に操作して、上下動用電動シリンダ２１ｃを伸長させて可動搬送コンベア２１ｂを最上昇位置まで上昇させて、図６に示すようにフレコンバッグ２２を載置台２６上方に持ち上げる。 First, the cross-directional control lever 27 is moved to the right to extend the vertical movement electric cylinder 21c and raise the movable transport conveyor 21b to its highest position, lifting the flexi-con bag 22 above the platform 26 as shown in FIG. 6.

そして、十字方向操作レバー２７を機体後方に操作して図７に示すように、回動用電動シリンダ２４ｃを伸長させて回動アーム２４ｂを枢支軸回りに回動して右外側方に開いて、フレコンバッグ２２を載置台２６の右外側方まで移動させる。 Then, the cross-directional control lever 27 is operated toward the rear of the machine body to extend the electric rotating cylinder 24c, rotate the rotating arm 24b around the pivot shaft, and open it to the right outside, as shown in Figure 7, and move the FIBC bag 22 to the right outside of the loading platform 26.

そして、十字方向操作レバー２７を左に操作して、上下動用電動シリンダ２１ｃを縮小させて可動搬送コンベア２１ｂを最下降位置まで下降させて、図８に示すようにフレコンバッグ２２を圃場に降ろす。 Then, the cross-directional control lever 27 is operated to the left to contract the vertical movement electric cylinder 21c and lower the movable transport conveyor 21b to its lowest position, and the flexi-con bag 22 is lowered into the field as shown in Figure 8.

そして、吊り下げハンガー２５の各フック２５ａをフレコンバッグ２２の上端縁部の係止孔から外して、十字方向操作レバー２７を操作して図４に示す状態に戻して、吊り下げハンガー２５の各フック２５ａに空のフレコンバッグ２２の上端縁部の係止孔を各々引っ掛けてフレコンバッグ２２を吊下げてフレコンバッグ２２の底が載置台２６に受けられた状態とした後に、補助作業座席２３に着座する。そして、各部を駆動して機体を進行させて収穫作業を再開する。 Then, each hook 25a of the hanging hanger 25 is released from the locking holes on the upper edge of the FIBC bag 22, and the cross-directional operating lever 27 is operated to return to the state shown in FIG. 4, and the locking holes on the upper edge of the empty FIBC bag 22 are hooked onto each hook 25a of the hanging hanger 25 to hang the FIBC bag 22 so that the bottom of the FIBC bag 22 is supported on the mounting platform 26, and then the operator sits on the auxiliary work seat 23. Then, each section is driven to move the machine forward and harvesting work is resumed.

そして、収穫作業が終えた後には、図９に示すように、十字方向操作レバー２７を操作して、可動搬送コンベア２１ｂを最上昇位置とし、回動アーム２４ｂを閉じた状態とし、作動アーム２４を基部アーム２４ａ基部の枢支部回りに機体内方に回動させて収納状態にする。載置台２６も基部枢支部回りに上方内方に回動させて収納状態とする。収納状態にすると、機体左右幅が小さくなるので、路上走行やトラックへの積み降ろしや納屋等への格納が容易になる。 After the harvesting work is completed, as shown in FIG. 9, the cross-directional operation lever 27 is operated to raise the movable transport conveyor 21b to the highest position, close the rotating arm 24b, and rotate the operating arm 24 around the pivot at the base of the base arm 24a into the machine body to store it in place. The platform 26 is also rotated upward and inward around the base pivot to store it in place. When in the stored state, the width of the machine body becomes smaller, making it easier to drive on the road, load and unload onto a truck, or store in a barn, etc.

以上要するに、吊り下げハンガー２５は、可動搬送コンベア２１ｂ右端部に設けた作動アーム２４により上下動及び左右動するので、吊り下げハンガー２５に吊り下げられた状態で載置台２６に載置されたフレコンバッグ２２を作動アーム２４により載置台２６上方に吊り上げて、載置台２６の右外側方の位置で圃場に降ろすことができ、圃場に降ろされたフレコンバッグ２２が傾いたり機体が多少蛇行したりしても、機体にフレコンバッグ２２が接触することを回避でき、良好で適切な収穫作業を行なうことができる。 In summary, the hanging hanger 25 moves up and down and left and right by the operating arm 24 attached to the right end of the movable transport conveyor 21b, so that the FIBC bag 22 placed on the platform 26 while suspended from the hanging hanger 25 can be lifted above the platform 26 by the operating arm 24 and lowered into the field at a position on the right outer side of the platform 26. Even if the FIBC bag 22 lowered into the field tilts or the machine meanders slightly, the FIBC bag 22 can be prevented from coming into contact with the machine, and good and proper harvesting work can be carried out.

＜他の実施態様＞ <Other embodiments>

（１）図１０は、第２実施形態を示し、作動アーム２４の他の例を示す。 (1) Figure 10 shows the second embodiment and another example of the actuating arm 24.

即ち、可動搬送コンベア２１ｂに基部を枢支した作動アーム２４は、基部が可動搬送コンベア２１ｂに枢支された右作動リンク３０及び電動シリンダ３１と該右作動リンク３０及び電動シリンダ３１の上端部に連結枢支された上部リンク３２にて構成されている。 That is, the operating arm 24, whose base is pivotally supported on the movable transport conveyor 21b, is composed of a right operating link 30 and an electric cylinder 31 whose base is pivotally supported on the movable transport conveyor 21b, and an upper link 32 that is connected and pivoted to the upper ends of the right operating link 30 and the electric cylinder 31.

上部リンク３２の先端には、吊り下げハンガー２５が装着されている。 A hanging hanger 25 is attached to the tip of the upper link 32.

従って、電動シリンダ３１を作動させると、吊り下げハンガー２５に吊り下げられたフレコンバッグ２２を載置台２６の右外側方の位置で圃場に降ろすことができる。 Therefore, when the electric cylinder 31 is operated, the flexi-con bag 22 suspended from the hanging hanger 25 can be lowered into the field at a position on the right outer side of the loading platform 26.

（２）図１１は、第３実施形態を示し、作動アーム２４の他の例を示す。 (2) Figure 11 shows the third embodiment and another example of the actuating arm 24.

即ち、作動アーム２４は、可動搬送コンベア２１ｂに固定した筒体３３と該筒体３３内を左右移動する作動杆３４にて構成される。そして、筒体３３内に挿通した作動杆３４基部は螺旋ネジ３４ａが形成されていて電動モータ３５の駆動にて該螺旋ネジ３４ａに係合する係合突起を有する回転リング３６が回転して、作動杆３４は機体左右方向に移動する。 That is, the operating arm 24 is composed of a cylinder 33 fixed to the movable transport conveyor 21b and an operating rod 34 that moves left and right inside the cylinder 33. A helical screw 34a is formed at the base of the operating rod 34 inserted into the cylinder 33, and a rotating ring 36 having an engagement protrusion that engages with the helical screw 34a is rotated by the drive of the electric motor 35, and the operating rod 34 moves left and right on the machine body.

そして、作動杆３４の右端部に吊り下げハンガー２５が装着されている。 A hanging hanger 25 is attached to the right end of the operating rod 34.

従って、電動モータ３５を作動させると、作動アーム２４の作動杆３４右端部に装着した吊り下げハンガー２５に吊り下げられたフレコンバッグ２２を載置台２６の右外側方の位置で圃場に降ろすことができる。 Therefore, when the electric motor 35 is operated, the flexi-con bag 22 suspended from the hanging hanger 25 attached to the right end of the operating rod 34 of the operating arm 24 can be lowered into the field at a position on the right outer side of the loading platform 26.

（３）図１２は、第４実施形態を示し、作動アーム２４の他の例を示す。 (3) Figure 12 shows the fourth embodiment and another example of the actuating arm 24.

即ち、作動アーム２４は、可動搬送コンベア２１ｂに固定した電動シリンダ３７と該電動シリンダ３７の先端部に設けたリンク３８にて構成される。そして、リンク３８の先端部に吊り下げハンガー２５が装着されている。 That is, the operating arm 24 is composed of an electric cylinder 37 fixed to the movable transport conveyor 21b and a link 38 attached to the tip of the electric cylinder 37. The hanging hanger 25 is attached to the tip of the link 38.

従って、電動シリンダ３７を伸長させると、吊り下げハンガー２５に吊り下げられたフレコンバッグ２２を載置台２６の右外側方の位置で圃場に降ろすことができる。 Therefore, when the electric cylinder 37 is extended, the flexi-con bag 22 suspended from the hanging hanger 25 can be lowered into the field at a position to the right outside of the loading platform 26.
