It is comprised with the guide inclination board 37b which guides a crop to the back inclination board 37a.

さらに、図１及び図２で示すとおり、前記排出シュータ３７の後方傾斜板３７ａの下方には、作物を回収するコンテナ等の回収容器３８を積載するための作物回収台３９を上下回動自在に配置する。該作物回収台３９は枠形状とし、枠内では前後方向の所定位置ごとに容器搬送ローラ４０・・・を回転自在に配置する。さらに、前記作物回収台３９はエアシリンダやトルクスプリング等によって上方に付勢して通常の回収位置に配置され、回収容器３８に収容される作物の重量が増加するにつれて下方傾斜姿勢となる、所謂ダンパ機構を備える。 Further, as shown in FIGS. 1 and 2, below the rear inclined plate 37a of the discharge shooter 37, a crop recovery table 39 for loading a recovery container 38 such as a container for recovering crops can be rotated up and down. Deploy. The crop collection base 39 is formed in a frame shape, and container transport rollers 40... Are rotatably arranged at predetermined positions in the front-rear direction within the frame. Further, the crop collection table 39 is urged upward by an air cylinder, a torque spring or the like, and is disposed at a normal collection position. The crop collection table 39 assumes a downward inclined posture as the weight of the crop stored in the collection container 38 increases. A damper mechanism is provided.

上記構成により、回収容器３８に所定重量以上の作物が収容されると作物回収台３９が自動的に下方回動するので、作物回収台３９から自動的に圃場に回収容器３８を下ろすことができ、作業者が手作業で重量の増加した回収容器３８を下ろす必要がなく、作業能率の向上や作業に要する労力の軽減が図られる。 With the above configuration, the crop collection table 39 automatically rotates downward when a crop of a predetermined weight or more is stored in the collection container 38, so that the collection container 38 can be automatically lowered from the crop collection table 39 to the field. Thus, it is not necessary for the operator to manually drop the collection container 38 whose weight has been increased, so that the work efficiency can be improved and the labor required for the work can be reduced.

なお、回収容器３８に収容される作物が無い、あるいは少量である段階では、作物回収台３９は機体後側に向かう上方傾斜姿勢となる配置とすると、回収容器３８も機体後側に向かう上方傾斜姿勢になるので、回収容器３８の底部が前記後方傾斜板３７ａに接近するので、後方傾斜板３７ａからの作物の落下距離が短くなり、落下の衝撃が弱まって作物が傷付くことが防止され、作物の商品価値が維持される。その後、作物回収台３９は、回収容器３８の重量が増加するにつれて後が下降する構成とすると、下降時に収容された作物を回収容器３８の後方に移動させることができるので、収容される作物が転がりながら均平化される。 When there is no crop stored in the collection container 38 or the quantity is small, the crop collection table 39 is arranged in an upward inclined posture toward the rear side of the aircraft, and the collection container 38 is also inclined upward toward the rear side of the aircraft. Since the bottom of the collection container 38 approaches the rear inclined plate 37a because it is in a posture, the fall distance of the crop from the rear inclined plate 37a is shortened, and the impact of the fall is weakened to prevent the crop from being damaged, The commercial value of the crop is maintained. Thereafter, if the crop collection stand 39 is configured to descend later as the weight of the collection container 38 increases, the crop stored at the time of lowering can be moved to the rear of the collection container 38, so It is leveled while rolling.

また、回収容器３８に所定重量まで作物が収容されたとき、圃場に回収容器３８を下ろしたくないときは、作物回収台３９がハンドルバー１３と略平行な姿勢となる位置まで回動するとそれ以上の下方回動を規制するロック部材（図示省略）を設けてもよい。このとき、図２に示すとおり、空の回収容器３８、及び作物が収容された回収容器３８を作業者が任意に載置する容器載置台４２を、拾上げ搬送装置２２の左右他側の外側で、且つ圃場面から浮かせて配置し、該容器載置台４２に作物が収容された回収容器３８を載置してもよい。 Further, when the crop is stored in the collection container 38 up to a predetermined weight, if it is not desired to lower the collection container 38 in the field, the crop collection table 39 can be rotated further to a position that is substantially parallel to the handlebar 13. You may provide the lock member (illustration omitted) which regulates below downward rotation. At this time, as shown in FIG. 2, an empty collection container 38 and a container mounting table 42 on which a worker arbitrarily places a collection container 38 in which crops are stored are arranged on the outer sides of the left and right sides of the pick-up conveyance device 22. In addition, the collection container 38 may be placed so as to float from the farm scene and the container placement table 42 may contain the crop.

上記構成では、回収容器３８に収容される作物の重量が所定重量を超えても作物回収台３９は下方回動しないので、回収容器３８の容量一杯に作物を回収することができ、回収容器３８を作物回収台３９に装填したり、作物回収台３９から容器載置台４２に作物を移動させたりする頻度が減少し、作業能率の向上や作業に費やす労力の軽減が図られる。 In the above configuration, even if the weight of the crop stored in the recovery container 38 exceeds a predetermined weight, the crop recovery table 39 does not rotate downward, so that the crop can be recovered to the full capacity of the recovery container 38. The frequency of loading the crop on the crop collection table 39 or moving the crop from the crop collection table 39 to the container mounting table 42 is reduced, so that the work efficiency can be improved and the labor spent on the work can be reduced.

また、作物が収容された回収容器３８を容器載置台４２に載置した状態で作業を継続することができるので、圃場の複数の位置を回って重量の増加した回収容器３８を集める必要がなく、作業能率が向上する。 Further, since the operation can be continued in a state where the collection container 38 containing the crop is placed on the container mounting table 42, it is not necessary to go around a plurality of positions in the field and collect the collection container 38 whose weight has increased. , Work efficiency is improved.

そして、図２に示すとおり、前記作物回収台３９の左右他側には、空の回収容器３８を載置すると共に、作物回収台３９から回収容器３８が取り除かれると空の回収容器３８を作物回収台３９に移動させる自動装填機構４３を設ける。該自動装填機構４３は、左右他側から左右一側に向かって下方傾斜する枠形状の装填枠４４を前記拾上げ搬送装置２２の後側で且つ下方に設け、該装填枠４４の空間部に複数の装填ローラ４５…を左右方向に所定間隔を空けて配置して構成する。なお、作物回収台３９に載置する回収容器３８の左右他側端部が、自動装填機構４３により左右一側端部に搬送された空の回収容器３８に接触することで、ストッパの役割を果たすものとする。 As shown in FIG. 2, empty collection containers 38 are placed on the left and right sides of the crop collection table 39. When the collection container 38 is removed from the crop collection table 39, the empty collection container 38 is removed from the crop collection table 39. An automatic loading mechanism 43 for moving to the collection table 39 is provided. The automatic loading mechanism 43 is provided with a frame-shaped loading frame 44 that is inclined downward from the left and right other sides toward the left and right sides, on the rear side and below the pick-up conveying device 22, and in the space portion of the loading frame 44. A plurality of loading rollers 45 are arranged at predetermined intervals in the left-right direction. The left and right other end portions of the collection container 38 placed on the crop collection table 39 come into contact with the empty collection container 38 conveyed to the left and right one end portions by the automatic loading mechanism 43, thereby serving as a stopper. To fulfill.

上記構成により、作物回収台３９が作物を回収している間は自動的に自動装填機構４３による空の回収容器３８の移動が規制され、作物回収台３９から回収容器３８が取り除かれると空の回収容器３８が装填ローラ４５によって左右一側に移動し、自動的に作物の回収を行う位置に載置されるので、回収容器３８の交換作業を行う際に機体の移動や拾上げ収穫作業を停止する時間が短くなり、作業能率が向上する。 With the above configuration, the movement of the empty collection container 38 by the automatic loading mechanism 43 is automatically regulated while the crop collection table 39 is collecting the crop, and the empty container is removed when the collection container 38 is removed from the crop collection table 39. The collection container 38 is moved to the left and right by the loading roller 45 and is automatically placed on the position where the crop is collected. Therefore, when the collection container 38 is exchanged, the body is moved or picked up and harvested. The time to stop is shortened and work efficiency is improved.

なお、図示を省略するが、拾上げ搬送装置２２の駆動を電動モータで行い、容器載置台４２に設けた重量計で回収容器３８が満杯になった重量を検出すると、電動モータの駆動を停止し、重量計が軽くなったことを検出して回収容器３８の交換作業が終了する時間の経過後に、電動モータを駆動するようにすると、容器載置台４２からの満杯回収容器３８の降ろし作業と空の回収容器３８の積込作業が作物の流れを一時的に停止して効率的に行える。この際に機体の走行も停止させると良い。 Although not shown in the figure, the pick-up conveyance device 22 is driven by an electric motor, and when the weight that the collection container 38 is full is detected by a weight meter provided on the container mounting table 42, the driving of the electric motor is stopped. Then, when the electric motor is driven after the elapse of time when the operation of replacing the collection container 38 is completed after detecting that the weight scale has become lighter, the operation of lowering the full collection container 38 from the container mounting table 42 is performed. The loading operation of the empty collection container 38 can be efficiently performed by temporarily stopping the flow of the crop. At this time, it is preferable to stop the running of the aircraft.

また、後方傾斜板３７ａに回収容器３８への作物移動を一時的に止める滞留板を設け、回収容器３８の交換作業時に該滞留板で作物を留めておけるようにすると、収集作業を続けながら回収容器３８の交換が行える。 Further, if a staying plate for temporarily stopping the movement of the crop to the collection container 38 is provided on the rear inclined plate 37a so that the crop can be held by the staying plate during the replacement operation of the collection container 38, the collection operation is continued. The container 38 can be replaced.

そして、図１及び図２に示すとおり、前記左右一側（機体左側）の搬送駆動スプロケット１７を設ける側で、且つ左右一側の搬送カバー２３と走行クローラ９Ｌの左右間に、前後方向の掻込伝動ケース４７を設け、該掻込伝動ケース４７を上下回動させる掻込昇降シリンダ４８を設ける。また、該掻込伝動ケース４７の内部には、前記搬送駆動スプロケット１７と同じく拾上げ駆動軸１６に装着する掻込駆動スプロケット４９と、機体前側に回転自在に配置する掻込従動スプロケット５０と、該掻込駆動スプロケット４９と掻込従動スプロケット５０に無端状に巻回する掻込伝動チェーン５１を設ける。 As shown in FIGS. 1 and 2, on the side where the left and right side (machine body left side) transport drive sprocket 17 is provided and between the left and right side transport cover 23 and the left and right of the traveling crawler 9L, A bayonet transmission case 47 is provided, and an elevating and lowering cylinder 48 for rotating the bayonet transmission case 47 up and down is provided. Further, in the drive transmission case 47, a drive drive sprocket 49 to be mounted on the pickup drive shaft 16 like the transport drive sprocket 17, a drive driven sprocket 50 rotatably arranged on the front side of the machine body, A take-up transmission chain 51 is provided around the take-up drive sprocket 49 and the take-up driven sprocket 50 so as to be wound endlessly.

なお、該掻込伝動チェーン５１の巻回域内には、弛み防止のテンションスプロケット（図示省略）を、一または複数設けてもよい。 One or more tension sprockets (not shown) for preventing slackening may be provided in the winding region of the drive transmission chain 51.

さらに、前記掻込従動スプロケット５０の従動回転軸５０ａの左右他側、即ち機体中央寄りとなる側に円柱形状の掻込ドラム５２を装着し、該掻込ドラム５２の外周に所定間隔を空けて複数の掻込アーム５３…を装着すると共に、各掻込アーム５３…にはゴム等の軟質部材で構成する掻込板５４を各々回動自在に設けて、掻込装置５５を構成する。 Further, a cylindrical scribing drum 52 is mounted on the left and right other sides of the driven rotation shaft 50a of the driven slave sprocket 50, that is, on the side closer to the center of the machine body, and a predetermined interval is provided around the outer periphery of the driving drum 52. A plurality of scrambling arms 53 are mounted, and each scrambling arm 53 is provided with a scoring plate 54 made of a soft member such as rubber so as to be rotatable to constitute a scrambling device 55.

該掻込装置５５は、側面視で反時計回り方向に回転し、前記拾上げ搬送装置２２の搬送始端部にある作物を掻込板５４で拾上げ搬送装置２２の搬送方向下手側に押し上げることで、作物が確実に搬送される状態とするものである。 The scraping device 55 rotates counterclockwise when viewed from the side, and picks up a crop at the transport start end of the pick-up transport device 22 by the pick-up plate 54 and pushes it up to the lower side in the transport direction of the transport device 22. Thus, the crop is surely conveyed.

上記構成により、作物が拾上げ搬送装置２２の搬送始端側に向かって転げ落ち、拾上げ前の作物と接触することや、畝溝に作物が落ちて左右の走行クローラ９Ｌ，９Ｒに踏み潰されることを防止できるので、作物が傷付いて商品価値が低下することが防止される。 With the above configuration, the crop falls down toward the transport start end side of the pick-up transport device 22 and comes into contact with the crop before pick-up, or the crop falls into the trough and is crushed by the left and right traveling crawlers 9L and 9R. Therefore, it is possible to prevent the crop value from being damaged and the commercial value from being lowered.

また、掻込装置５５が作物を拾上げ搬送装置２２の搬送方向下手側に作物を移動させることにより、拾上げ搬送装置２２の搬送始端部に作物が滞留することを防止できるので、作業者が拾上げ搬送装置２２から作物を拾上げる作業が不要になり、作業能率の向上や作業に要する労力の軽減が図られる。 Further, since the scraping device 55 picks up the crop and moves the crop to the lower side in the transport direction of the transport device 22, it is possible to prevent the crop from staying at the transport start end of the pick-up transport device 22. The work of picking up crops from the pick-up / conveying device 22 becomes unnecessary, so that the work efficiency can be improved and the labor required for the work can be reduced.

前記拾上げ搬送装置２２と掻込装置５５は、駆動力を共通の拾上げ駆動軸１６から得ることにより、拾上げ搬送速度と掻き込み回転速度を同調させ、いっそう作物が圃場に戻ることや、畝溝に落下することを防止している。しかしながら、その分駆動に要する力が大きくなるので、拾上げ搬送装置２２の搬送始端部が土砂に突っ込んだり、掻込装置５５と拾上げ搬送装置２２の上下間に作物が停滞したりすると、過負荷が拾上げ回転軸１６に加わり、破損する可能性がある。 The pick-up transport device 22 and the pick-up device 55 obtain driving force from the common pick-up drive shaft 16 to synchronize the pick-up transport speed and the pick-up rotation speed, and the crop returns to the field, Prevents falling into the trough. However, since the force required for driving increases accordingly, if the transport start end portion of the pick-up transport device 22 pierces the earth or sand, or if the crop stagnates between the upper and lower sides of the pick-up device 55 and the pick-up transport device 22, A load is picked up and applied to the rotary shaft 16 and may be damaged.

この問題を防止すべく、過負荷、即ち所定値以上のトルクがかかる状態になると、搬送駆動スプロケット１７を空回りさせて拾上げ回転軸１６の回転を停止させるトルクリミッタ５６を、図３に示すとおり、該拾上げ搬送装置２２の左右一側で且つ左側一側の搬送カバー２３の内部に設ける。該トルクリミッタ５６は、前記搬送駆動スプロケット１７を左右から挟み込ませて配置して、該トルクリミッタ５６が非伝動状態になると搬送駆動スプロケット１７の回転を停止させる構成とする。そして、該搬送駆動スプロケット１７の左右他側面を掻込駆動スプロケット４９の左右一側面に沿わせ、搬送駆動スプロケット１７の回転が停止すると掻込駆動スプロケット４９も停止する構成とする。 In order to prevent this problem, as shown in FIG. 3, a torque limiter 56 that stops the rotation of the pick-up rotating shaft 16 by causing the transport drive sprocket 17 to idle when an overload, that is, when a torque exceeding a predetermined value is applied. The pick-up and transfer device 22 is provided inside the transfer cover 23 on the left and right sides and on the left side. The torque limiter 56 is arranged so that the transport drive sprocket 17 is sandwiched from the left and right, and the rotation of the transport drive sprocket 17 is stopped when the torque limiter 56 is in a non-transmission state. Then, the left and right other side surfaces of the transport drive sprocket 17 are arranged along the left and right side surfaces of the pick-up drive sprocket 49, and when the rotation of the transport drive sprocket 17 stops, the pick-up drive sprocket 49 also stops.

前記トルクリミッタ５６は、前記搬送駆動スプロケット１７の左右に各々ブレーキライニング５７，５７を設け、左右一側には左側のブレーキライニング５７に接触して摩擦をかける補助ライニング５８を設ける。該補助ライニング５８の左右一側端部には平面視で凹形状となる凹部５８ａを形成し、該凹部５８ａに皿バネ５９の外周縁端部を接触させる。そして、該皿バネ５９の左右一側には、補助ライニング５８に接する皿バネ５９の強弱を調節してトルクを増減させる、トルク調節ハンドル６０を回転操作可能に設ける。 The torque limiter 56 is provided with brake linings 57, 57 on the left and right sides of the transport drive sprocket 17, and an auxiliary lining 58 that contacts the left brake lining 57 and applies friction to the left and right sides. A concave portion 58a having a concave shape in plan view is formed at the left and right side end portions of the auxiliary lining 58, and the outer peripheral edge portion of the disc spring 59 is brought into contact with the concave portion 58a. On the left and right sides of the disc spring 59, a torque adjustment handle 60 for adjusting the strength of the disc spring 59 in contact with the auxiliary lining 58 to increase or decrease the torque is provided to be rotatable.

一方、左右他側のブレーキライニング５７は、前記拾上げ回転軸１６の外周に設けるリミッタハブ６１の左右一側端部に接触する構成とする。該リミッタハブ６１のうち、左右他側のブレーキライニング５７と接触する面よりも左右他側には、トルク測定用のレンチを接触させる、トルク測定部６１ａを形成する。また、リミッタハブ６１の左右一側端部には、該リミッタハブ６１を拾上げ回転軸１６に装着するナット６２が入り込む左右方向の凹部６１ｂを形成し、該凹部６１ｂにナット６２が内装される構成とする。 On the other hand, the left and right brake linings 57 are configured to come into contact with the left and right side ends of a limiter hub 61 provided on the outer periphery of the pick-up rotary shaft 16. In the limiter hub 61, a torque measuring portion 61a is formed on the other side of the left and right sides of the limiter hub 61 with respect to the brake lining 57 on the other side. In addition, a left and right recess 61b into which a nut 62 for picking up the limiter hub 61 and attaching it to the rotary shaft 16 is formed at the left and right end portions of the limiter hub 61, and the nut 62 is housed in the recess 61b. To do.

なお、該トルク調節ハンドル６０は、リミッタハブ６１の左右一側の外周部に設けるものとする。 The torque adjustment handle 60 is provided on the outer peripheral portion on the left and right sides of the limiter hub 61.

上記構成により、拾上げ搬送装置２２及び掻込装置５５に所定トルク以上の過負荷がかかると左右のブレーキライニング５７，５７及び補助ライニング５８が接触して搬送駆動スプロケット１７を空回りさせることにより、拾上げ回転軸１６の回転が停止すると共に掻込駆動スプロケット４９も回転しなくなり、過負荷が発生し得る状態で拾上げ搬送装置２２や掻込装置５５が作動することを防止できるので、拾上げ回転軸１６が過負荷で破損することが防止される。 With the above configuration, when an overload of a predetermined torque or more is applied to the pick-up transport device 22 and the scraping device 55, the left and right brake linings 57, 57 and the auxiliary lining 58 come into contact with each other to cause the transport drive sprocket 17 to idle, Since the rotation of the lifting rotary shaft 16 stops and the pick-up drive sprocket 49 also stops rotating, it is possible to prevent the pick-up conveying device 22 and the pick-up device 55 from operating in a state where an overload can occur. The shaft 16 is prevented from being damaged due to overload.

また、リミッタハブ６１の左右一側端部に凹部６１ｂを設けたことにより、ナット６２がリミッタハブ６１の左右幅内に収まるので、トルクリミッタ５６の左右一側に突出する部材がなくなり、トルクリミッタ５６の左右幅を短く構成することで、機体の左右幅のコンパクト化が図られる。 Further, by providing the recess 61b at the left and right side end portions of the limiter hub 61, the nut 62 fits within the left and right width of the limiter hub 61, so that there is no member protruding to the left and right sides of the torque limiter 56, and the torque limiter 56 By making the left and right width short, the left and right width of the aircraft can be made compact.

そして、トルク調節ハンドル６０をリミッタハブ６１の左右一側の外周部に設けたことにより、左側の搬送カバー２３を外すとすぐにトルク調節ハンドル６０を操作することができるので、圃場の土質や作物の拾上げ開始高さに合わせてトルクリミッタ５６の作用するトルクを設定することができるので、拾上げ回転軸１６が破損する前に駆動力の伝動を止めることができ、拾上げ収穫作業の中断が防止される。 Since the torque adjustment handle 60 is provided on the left and right outer peripheral portions of the limiter hub 61, the torque adjustment handle 60 can be operated as soon as the left transport cover 23 is removed. Since the torque applied by the torque limiter 56 can be set in accordance with the pick-up start height, transmission of the driving force can be stopped before the pick-up rotating shaft 16 is broken, and the pick-up harvesting operation is interrupted. Is prevented.

さらに、拾上げ搬送装置２２だけでなく掻込装置５５の回転を停止させることにより、作業者が視覚的にトルククラッチ５６の作動を確認することができるので、拾上げ搬送装置２２や掻込装置５５の停止に気付かず機体を前進させることが防止され、余分な作業が行われず、作業能率が向上する。 Furthermore, by stopping the rotation of not only the pick-up transport device 22 but also the pick-up device 55, the operator can visually confirm the operation of the torque clutch 56, so that the pick-up transport device 22 and the pick-up device It is possible to prevent the aircraft from moving forward without noticing the stop of 55, so that no extra work is performed and work efficiency is improved.

また、リミッタハブ６１にトルク測定部６１ａを形成したことにより、トルク測定用のレンチを噛み合わせる場所がわかりやすいので、トルク測定作業の能率が向上すると共に、トルク値の測定が行いやすく、トルク値の設定間違いによる破損が防止される。 In addition, since the torque measuring part 61a is formed in the limiter hub 61, the location where the torque measuring wrench is engaged is easily understood, so that the efficiency of the torque measuring work is improved, the torque value is easily measured, and the torque value is set. Damage due to mistakes is prevented.

なお、前記左右のブレーキライニング５７，５７、及び補助ライニング５８同士が接触するとカチカチという音を発生させるべく、左右のブレーキライニング５７，５７及び補助ライニング５８の接触面に音を生じさせる発音突起（図示省略）を形成すると、掻込装置５５の回転停止だけでなくトルククラッチ５６の作動音で過負荷の発生の可能性を作業者に報知することができるので、作業者に過負荷発生の原因を早期に解消させることができる。 In order to generate a clicking sound when the left and right brake linings 57 and 57 and the auxiliary lining 58 come into contact with each other, a sounding protrusion (not shown) that generates a sound on the contact surfaces of the left and right brake linings 57 and 57 and the auxiliary lining 58 is illustrated. (Not shown), the operator can be notified of the possibility of an overload not only by stopping the rotation of the take-in device 55 but also by the operating sound of the torque clutch 56. It can be resolved early.

また、トルク測定部６１ａに追加または交換用の皿バネ５９を設け、補助ライニング５８の凹部５８ａに入り込む皿バネ５９が破損した時に交換することにより、皿バネ５９を機外まで取りに行く必要が無くなり、作業能率や、皿バネ５９の交換に要する時間と労力が軽減される。 Further, it is necessary to provide an additional or replacement disc spring 59 in the torque measuring unit 61a and replace the disc spring 59 entering the concave portion 58a of the auxiliary lining 58 when it is damaged, so that the disc spring 59 needs to be taken outside the machine. As a result, the work efficiency and the time and labor required to replace the disc spring 59 are reduced.

あるいは、皿バネ５９が一枚だけでは十分なトルクが生じないときは、皿バネ５８を重ねることにより、高いトルクを設定できるようになるので、作業条件に適したトルクリミッタ５６の設定が可能になる。 Alternatively, when sufficient torque is not generated with only one disc spring 59, a high torque can be set by overlapping the disc spring 58, so that it is possible to set the torque limiter 56 suitable for the working conditions. Become.

図４及び図５に示すとおり、前記トルクリミッタ５６にスリップを検出するスリップセンサ６３を設け、該スリップセンサ６３の検出値を制御装置６４に発信し、該制御装置６４を介して前記トラニオン回動モータ１１ｂを作動させ、前記トラニオン軸の回動量を変更することにより、無段変速装置１１の出力を低下させる構成としてもよい。 As shown in FIGS. 4 and 5, the torque limiter 56 is provided with a slip sensor 63 for detecting slip, and the detected value of the slip sensor 63 is transmitted to the control device 64, and the trunnion rotation is performed via the control device 64. It is good also as a structure which reduces the output of the continuously variable transmission 11 by operating the motor 11b and changing the rotation amount of the said trunnion shaft.

上記構成により、トルクリミッタ５６の作動時のスリップ率に合わせて無段変速装置１１の出力を低下させることにより、拾上げ収穫作業の走行速度を低下させることができるので、拾上げ搬送装置２２や掻込装置５５に負荷がかかりにくくなるので、過負荷による破損が防止される。スリップ率と変速装置１１の出力低下は、スリップ率が高くなるほど出力が低下する、反比例の関係とする。 With the above configuration, the traveling speed of the picking and harvesting work can be reduced by reducing the output of the continuously variable transmission 11 in accordance with the slip rate when the torque limiter 56 is operated. Since it becomes difficult to apply a load to the take-in device 55, damage due to an overload is prevented. The slip ratio and the output reduction of the transmission 11 have an inversely proportional relationship in which the output decreases as the slip ratio increases.

なお、スリップ率が所定高さを超えると、その分高い負荷がかかっていると判断できるので、破損防止のために無段変速装置１１の出力を停止させる制御としてもよい。 If the slip ratio exceeds a predetermined height, it can be determined that a high load is applied accordingly, so that the output of the continuously variable transmission 11 may be stopped to prevent breakage.

本発明は、機体の進行方向を変更することなく、容易に幅広く作物を収穫できるので、圃場面に掘り起こして放置した玉葱やニンニク等の作物を拾上げて収穫する作物拾上げ収穫機に有用である。 Since the present invention can easily harvest a wide variety of crops without changing the traveling direction of the aircraft, it is useful for a crop picking and harvesting machine that picks up and harvests crops such as onions and garlic that have been dug up and left in the field. is there.
