Description

本発明は、コンバインに係るものである。 The present invention relates to a combine.

従来より、植立穀稈を分草する分草装置と、該分草装置によって分草された穀稈を引き起こす引起装置と、該引起装置によって引き起こされた穀稈を切断する刈刃と、該刈刃によって切断した穀稈を搬送する掻込み搬送装置とから刈取部を構成して該刈取部を機体前部に昇降自在に設けたコンバインが知られている。 Conventionally, a weeding device for weeding a planted culm, a pulling device for causing a culm weeded by the weeding device, a cutting blade for cutting the culm caused by the pulling device, 2. Description of the Related Art There is a known combine that includes a cutting and conveying device that conveys cereals cut by a cutting blade and that includes a cutting unit that can be moved up and down at the front of the machine body.

そして、このようなコンバインにおいて、刈取部の上部に回動軸心を横向き姿勢に配置し、該回動軸心を支点として分草装置と引起装置とを一体的に上方回動自在に構成し、該分草装置と引起装置とを積極的に上下回動させる駆動装置を設けたものがある（例えば、特許文献１参照。）。このような構成を採ることにより、刈刃の前方に位置する分草装置と引起装置とを上方へ退避させ、刈刃を畦際に接近させてこの畦際に植立する穀稈を刈り取ることができるものとし、枕地での手刈り作業を省力化しようとするものである。尚、この技術は、コンバインが作業対象の圃場に初めて侵入する際（刈り込み時）にも利用できる。
特開２００４−２４１１２号公報 In such a combine, a rotating shaft center is arranged in a horizontal posture on the upper part of the cutting part, and the weeding device and the pulling device are configured to be freely rotatable upward with the rotating shaft center as a fulcrum. There is one provided with a drive device that positively rotates the weeding device and the pulling device up and down (see, for example, Patent Document 1). By adopting such a configuration, the weeding device and the pulling device located in front of the cutting blade are retreated upward, and the cutting blade is brought close to the heel and the grain culm planted on the heel is cut off. It is intended to save labor for hand mowing on the headland. This technique can also be used when the combine first enters the field to be worked (when cutting).
JP 2004-24112 A

上述のような従来技術において、コンバインによる刈取作業中は、操縦者が、右手で操向レバ−を把持し、左手で変速レバ−を把持して操縦を行なう。
そして、コンバインが穀稈列の終端部に至った際に、左手で変速レバ−を減速操作して機体を減速ないし停止させ、駆動装置の作動状態を操作する操作具を操作して、分草装置と引起装置とを駆動装置の駆動力によって一体的に上方回動させれば、刈刃よりも前方の構造物がなくなるために、更に変速レバ−を前進操作して刈刃を比較的高い畦畔や壁面に近付け、この際の植立穀稈を刈り取ることができる。即ち、このように分草装置と引起装置とを一体的に上方回動させる構成を採用すれば、畦畔や壁面などの障害物の高さに関係なく、この畦際の植立穀稈を刈り取ることができる。 In the prior art as described above, during the harvesting operation by the combiner, the operator holds the steering lever with the right hand and controls the shift lever with the left hand.
Then, when the combine reaches the end of the grain row, the left hand decelerates the shifting lever to decelerate or stop the machine, and operates the operating tool for operating the operating state of the driving device. If the device and the pulling device are integrally rotated upward by the driving force of the driving device, the structure ahead of the cutting blade is eliminated, so that the shift lever is further advanced to make the cutting blade relatively high. The planted cereals at this time can be harvested. That is, by adopting a structure in which the weeding device and the pulling device are integrally rotated upward in this way, the planted cereal rice cake at the edge of the cocoon can be used regardless of the height of obstacles such as the shoreline or the wall surface. Can be reaped.

しかしながら、このように分草装置と引起装置とを上下回動させるにあたり、駆動装置の作動状態を操作する操作具が、例えば操縦席前方の前部操作パネルに設けられていると、コンバインが穀稈列の終端部に至った時点で操向レバ−から右手を離し、この右手で操作具を操作せねばばらず、この間、操向レバ−による機体の操向や刈取部の昇降操作が行なえなくなり、作業能率が低下する欠点がある。 However, when the operation tool for operating the operating state of the driving device is provided on the front operation panel in front of the cockpit, for example, when the weeding device and the pulling device are turned up and down in this way, the combine is When you reach the end of the row, you must release the right hand from the steering lever and operate the operating tool with this right hand. During this time, you can use the steering lever to steer the aircraft and raise and lower the cutting part. There is a drawback that work efficiency is reduced.

また、操作具が、例えば操縦席側方の側部操作パネルに設けられていると、コンバインが穀稈列の終端部に至った時点で変速レバ−から左手を離し、この左手で操作具を操作せねばならず、この間、変速レバ−による変速操作ないし前後進操作が行なえなくなり、作業能率が低下する欠点がある。 Further, when the operation tool is provided on the side operation panel on the side of the cockpit, for example, the left hand is released from the shift lever when the combine reaches the end of the row of culms, and the operation tool is operated with the left hand. During this period, there is a disadvantage that the shift operation or the forward / reverse operation by the shift lever cannot be performed, and the work efficiency is lowered.

本発明は、上述した課題を解決するために、次の如き技術手段を講ずるものである。

In this case, the electric motor 40 of the moving mechanism 39 is constituted by a motor with a brake mechanism, and the upper transmission case 36 is rotated when the electric motor 40 is not energized. It may be configured to lock.

そして、図５に示すように、前記電動モ−タ４０の回転を調節操作する操作スイッチ（操作具）ＳＷ１を、機体Ｋの走行方向調節用の操向レバ−５２の把持部の上面に設ける。
また、図６に示すように、該操作スイッチＳＷ１を、機体の走行速度調節用の変速レバ−５１の把持部の内側面部に設けてもよい。 As shown in FIG. 5, an operation switch (operation tool) SW1 for adjusting the rotation of the electric motor 40 is provided on the upper surface of the grip portion of the steering lever 52 for adjusting the traveling direction of the machine body K. .
In addition, as shown in FIG. 6, the operation switch SW <b> 1 may be provided on the inner side surface portion of the grip portion of the shift lever 51 for adjusting the traveling speed of the airframe.

前記操作スイッチＳＷ１は、いずれも２方向に押し操作するシ−ソ−式に形成し、一方向側に押すと前記電動モ−タ４０が正転し、一方、他方向側に押し操作すると前記電動モ−タ４０が逆転するように制御回路を構成する。 Each of the operation switches SW1 is formed in a seesaw type that is operated to push in two directions. When the operation switch SW1 is pushed in one direction, the electric motor 40 rotates in the forward direction. The control circuit is configured so that the electric motor 40 is reversed.

この制御回路は、図７に示すように、コントロ−ラＣＴに対して、その入力側に操作スイッチＳＷ１を接続する一方、その出力側に電動モ−タ４０を接続して構成する。
また、上部伝動ケ−ス３６内に設けた伝動軸４３に受動プ−リ４４を設け、該受動プ−リ４４と側部フレ−ム２７の中間部から突出する出力軸に設けた出力プ−リ４５との間にベルト４６を掛け回す。そして、前記伝動軸４３の両端部に設けたベベルギヤＧ１，Ｇ２に、左右の伝動筒３５，３５内の伝動軸３５Ｓ，３５Ｓの上端部に設けたベベルギヤｇ１，ｇ２を噛み合わせる。更に、前記伝動軸３５Ｓ，３５Ｓの下端部に設けたベベルギヤｇ３，ｇ４と、前記横軸３２，３２の後端部に設けたベベルギヤｇ５，ｇ６とをベベルギヤケ−スＧ３，Ｇ４内で噛み合わせる。この伝動構成により、引起装置９は、その上下回動位置に拘らず、駆動することができる。 As shown in FIG. 7, this control circuit is configured by connecting an operation switch SW1 to the input side of the controller CT and connecting an electric motor 40 to the output side thereof.
Further, a passive pulley 44 is provided on the transmission shaft 43 provided in the upper transmission case 36, and an output pulley provided on the output shaft protruding from the intermediate portion between the passive pulley 44 and the side frame 27. -The belt 46 is hung around the belt 45. The bevel gears G1 and G2 provided at the upper end portions of the transmission shafts 35S and 35S in the left and right transmission cylinders 35 and 35 are meshed with the bevel gears G1 and G2 provided at both ends of the transmission shaft 43, respectively. Further, the bevel gears g3 and g4 provided at the lower end portions of the transmission shafts 35S and 35S and the bevel gears g5 and g6 provided at the rear end portions of the horizontal shafts 32 and 32 are meshed in the bevel gear cases G3 and G4. With this transmission configuration, the pulling device 9 can be driven regardless of its vertical rotation position.

また、前記出力プ−リ４５と受動プ−リ４４とに掛け回すベルト４６による巻き掛け伝動系は、前記受動プ−リ４４を有効直径変更可能な割プ−リに構成して、伝動比率を無段階に変更可能なベルト変速ユニットと成す。該ベルト変速ユニットを変速作動させることにより、前記引起装置９の駆動歯車３３の回転速度が変速され、該駆動歯車３３に巻き掛けられたチェンＣおよび該チェンＣに取り付けられた引起ラグ３４の上昇移行速度（引起速度）が変速される構成とする。 Further, the winding transmission system by the belt 46 wound around the output pulley 45 and the passive pulley 44 is constituted by a split pulley which can change the effective diameter of the passive pulley 44, and the transmission ratio Is a belt transmission unit that can be changed steplessly. By rotating the belt transmission unit, the rotational speed of the drive gear 33 of the pulling device 9 is changed, and the chain C wound around the drive gear 33 and the raising lug 34 attached to the chain C are raised. The transition speed (the pulling speed) is changed.

更に、前記ベルト変速ユニットの受動プ−リ４４の有効直径を変更する機構として、該受動プ−リ４４の有効直径を調節するカム機構（図示省略）を操作するロッド４７と前記刈取部４側の縦支持フレ−ム２２の中間部とに連繋ワイヤ４８のインナ−側の両端部を連結し、前記電動モ−タ４０を収容するケ−シング４９とミッションケ−ス５０前側とに前記連繋ワイヤ４８のアウタ−側の両端部を連結する。これにより、刈取上下シリンダ１９を伸長作動させて刈取部４を機体Ｋに対して上昇させると、前記連繋ワイヤ４８のインナ−側の引き操作によって、前記ロッド４７が引かれてカム機構が作動し、ベルト変速ユニットの受動プ−リ４４の有効直径が変化して、引起装置９の駆動歯車３３の回転速度が増速する。これによって、該駆動歯車３３に巻き掛けるチェンＣおよび引起ラグ３４の上昇移行速度、即ち引起速度が増速する。 Further, as a mechanism for changing the effective diameter of the passive pulley 44 of the belt transmission unit, a rod 47 for operating a cam mechanism (not shown) for adjusting the effective diameter of the passive pulley 44 and the cutting part 4 side. The inner end of the connecting wire 48 is connected to the middle portion of the vertical support frame 22 and the connecting portion 49 for housing the electric motor 40 and the front side of the transmission case 50 are connected. Both ends of the outer side of the wire 48 are connected. Accordingly, when the cutting upper and lower cylinders 19 are extended and the cutting unit 4 is raised with respect to the machine body K, the rod 47 is pulled by the inner pulling operation of the connecting wire 48, and the cam mechanism is operated. The effective diameter of the passive pulley 44 of the belt transmission unit changes, and the rotational speed of the drive gear 33 of the pulling device 9 increases. As a result, the rising transition speed of the chain C and the pulling lug 34 wound around the drive gear 33, that is, the pulling speed is increased.

しかして、コンバイン作業においては、操縦者が操縦部７に設けた変速レバ−５１を左手で把持して前進増速操作して走行装置２を駆動すると共に、該操縦者が右手で操向レバ−５２を把持して機体Ｋの走行方向を調節したり刈取部４の高さを調節したりしながら、刈取部４の分草装置８によって圃場の植立穀稈を分草し、分草された穀稈を引起装置９によって引起し、この引起された穀稈を刈刃１０によって切断し、この切断された穀稈を搬送装置１１から株元搬送装置１４と穂先搬送装置とに引継ぎ、扱ぎ深さ自動制御手段による扱ぎ深さの自動制御が行われて、後方のフィ−ドチェン１６に引き継がれて脱穀処理される。 Thus, in the combine work, the operator grips the shift lever 51 provided in the control unit 7 with the left hand and operates forward speeding to drive the traveling device 2, and the driver operates the steering lever with the right hand. -52, while adjusting the traveling direction of the machine body K and adjusting the height of the cutting unit 4, the weeding device 8 of the cutting unit 4 is used to weed the planted cereal grains in the field, The raised cedar is caused by the pulling device 9, the raised cereal is cut by the cutting blade 10, and the cut cereal is handed over from the transport device 11 to the stock transport device 14 and the tip transport device, The handling depth is automatically controlled by the handling depth automatic control means, and is taken over by the rear feed chain 16 and threshing processed.

このようなコンバイン作業において、例えば圃場の一辺を刈り終えて畦際に達したときに、この畦が比較的高く、刈取部４を上昇させても分草装置８等が干渉する場合には、操縦者が右手で把持した操向レバ−５２の把持部上面の操作スイッチＳＷ１を一方向側へ押し操作することによって、あるいは操縦者が左手で把持した変速レバ−５１の把持部内側面部の操作スイッチＳＷ１を一方向側へ操作することにより、コントロ−ラＣＴからの出力によって電動モ−タ４０を正転駆動して、刈取部４の上部に横向き姿勢に配置する回動軸心Ｓを支点として分草装置８と引起装置９とを一体的に上方回動させる。これにより、分草装置８や引起装置９を畦に干渉させることなく、刈刃１０を畦に接近させてこの畦際の植立穀稈を刈り取ることができ、手刈り作業を省力化できる。この後、前記操作スイッ
チＳＷ１を他方向側へ押し操作すると、コントロ−ラＣＴからの逆出力によって電動モ−タ４０が逆転して、刈取部４の上部に横向き姿勢に配置する回動軸心Ｓ（伝動軸４３の軸心に同じ）を支点として分草装置８と引起装置９とを一体的に下方回動させ、元の通常の刈取作業位置へ復帰させる。 In such a combine work, for example, when the side of the field has been cut and the culm has been reached, if the culm is relatively high and the weeding device 8 or the like interferes even when the mowing unit 4 is raised, Operation of the inner side surface portion of the gripping portion of the shift lever 51 held by the operator by pushing the operation switch SW1 on the upper surface of the gripping portion of the steering lever 52 held by the right hand in one direction or by the operator. By operating the switch SW1 in one direction, the electric motor 40 is rotated forward by the output from the controller CT, and the pivot axis S arranged in the lateral posture is arranged at the upper portion of the cutting unit 4 as a fulcrum. The weeding device 8 and the pulling device 9 are integrally rotated upward. Thereby, without causing the weeding device 8 and the pulling device 9 to interfere with the cocoon, the cutting blade 10 can be brought close to the cocoon and the planted cereal cocoon can be trimmed, and the labor for hand-cutting can be saved. After that, when the operation switch SW1 is pushed in the other direction, the electric motor 40 is reversed by the reverse output from the controller CT, and the rotation shaft centered in the horizontal posture on the upper portion of the cutting unit 4 is arranged. Using S (same as the axis of the transmission shaft 43) as a fulcrum, the weeding device 8 and the pulling device 9 are integrally rotated downward to return to the original normal cutting operation position.

尚、上記の操作スイッチＳＷ１は、該操作スイッチＳＷ１を一方向側または他方向側へ押し操作している間だけ電動モ−タ４０を駆動させるものであるが、該操作スイッチＳＷ１を一方向側へワンプッシュするだけで、分草装置８と引起装置９とが上限位置に達するまで電動モ−タ４０が駆動し続けた後、該電動モ−タ４０が自動的に停止するようにコントロ−ラＣＴを設定してもよい。これにより、操作スイッチＳＷ１を一方向側へワンプッシュして手を離し、分草装置８と引起装置９とが上昇している間に、再び操向レバ−５２または変速レバ−５１を把持して操縦が行えるため、畦際での刈取作業の操作性を更に向上させることができる。 The operation switch SW1 drives the electric motor 40 only while the operation switch SW1 is pushed in one direction or the other direction. The electric motor 40 continues to be driven until the weeding device 8 and the pulling device 9 reach the upper limit position, and the controller is automatically stopped so that the electric motor 40 automatically stops. La CT may be set. As a result, the operation switch SW1 is pushed once in one direction to release the hand, and the steering lever 52 or the shift lever 51 is held again while the weeding device 8 and the pulling device 9 are raised. Therefore, it is possible to further improve the operability of the cutting operation at the shore.

また、このように操作スイッチＳＷ１を一方向側にワンプッシュして分草装置８と引起装置９とが自動的に上昇する際に、この分草装置８と引起装置９との上昇位置を検出するセンサを設けて該センサを前記コントロ−ラＣＴの入力側に接続し、該センサが、分草装置８と引起装置９が収納状態にある排出オ−ガ６に接近したことを検出した場合に、コントロ−ラＣＴからの出力が停止して電動モ−タ４０の駆動を自動的に停止させるように構成してもよい。このように構成することにより、刈取部４の上方に位置する排出オ−ガ６に分草装置８や引起装置９が衝突して破損するのを防止することができる。 Further, when the weeding device 8 and the pulling device 9 are automatically raised by pushing the operation switch SW1 in one direction in this way, the rising positions of the weeding device 8 and the pulling device 9 are detected. The sensor is connected to the input side of the controller CT, and the sensor detects that the weeding device 8 and the pulling device 9 have approached the discharge organ 6 in the retracted state. In addition, the output from the controller CT may be stopped and the driving of the electric motor 40 may be automatically stopped. By configuring in this way, it is possible to prevent the weeding device 8 and the pulling device 9 from colliding with and being damaged by the discharge agar 6 positioned above the cutting unit 4.

更に、前記操作スイッチＳＷ１を一方向側にワンプッシュして電動モ−タ４０が逆転して分草装置８と引起装置９とが上限位置まで上昇して自動的に停止した後、操作スイッチＳＷ１を他方向側へワンプッシュすることによって、分草装置８と引起装置９とが通常の刈取作業状態へ下降復帰するまで電動モ−タ４０が逆転した後、自動的に停止するように前記コントロ−ラＣＴを設定してもよい。これにより、操作スイッチＳＷ１を他方向側へワンプッシュして手を離し、分草装置８と引起装置９とが下降している間に、再び操向レバ−５２または変速レバ−５１を把持して操縦が行えるため、畦際での刈取作業の操作性を更に向上させることができる。 Further, after the operation switch SW1 is pushed once in one direction and the electric motor 40 is reversed, the weeding device 8 and the pulling device 9 are raised to the upper limit position and automatically stopped, and then the operation switch SW1. Is pushed in the other direction so that the electric motor 40 reverses until the weeding device 8 and the pulling device 9 return to the normal cutting operation state, and then the controller is automatically stopped. -La CT may be set. As a result, the operation switch SW1 is pushed once in the other direction and released, and the steering lever 52 or the shift lever 51 is again gripped while the weeding device 8 and the pulling device 9 are lowered. Therefore, it is possible to further improve the operability of the cutting operation at the shore.

また、前記操作スイッチＳＷ１は、上述のようにシ−ソ−型に構成する以外に、単なる常開接点式に構成して、該操作スイッチＳＷ１の１回目ワンプッシュによって電動モ−タ４０が正転を開始し、２回目のワンプッシュによって電動モ−タ４０が逆転を開始するように前記コントロ−ラＣＴを設定してもよい。 In addition to the seesaw type configuration as described above, the operation switch SW1 is configured as a mere normally open contact type, and the electric motor 40 is positively operated by the first one-push of the operation switch SW1. The controller CT may be set so that the electric motor 40 starts reverse rotation by the second one-push.

更に、上述のように操作スイッチＳＷ１を操作して、分草装置８と引起装置９が上昇した状態では、操向レバ−５２を左右に傾倒操作しても、機体Ｋの走行方向が調節されないように構成してもよい。即ち、前記コントロ−ラＣＴと本機側のコントロ−ラを通信ラインで接続し、分草装置８と引起装置９が上昇位置にあることをセンサが検出している間は、操向レバ−５２を左右に傾倒操作しても、ミッションケ−ス５０内に設けた左右のサイドクラッチ伝動遮断状態に切り換わらないように前記コントロ−ラＣＴから本機側のコントロ−ラへ信号を送信するように設定し、牽制手段を形成するものである。即ち、畦際で分草装置８と引起装置９を上昇させて刈刃１０が露出している状態において、誤操作等によって操向レバ−５２が急激に傾倒操作されると、機体Ｋが急旋回して、刈刃１０等を畦に突っ込ませて破損するおそれがあるうえに、付近の作業者にとっても危険であるが、上記のように牽制手段を設けることによって、刈刃１０等を畦に突っ込ませて破損させるような事態が起こりにくく、安全性を向上させることができる。 Furthermore, when the operation switch SW1 is operated as described above and the weeding device 8 and the pulling device 9 are raised, the traveling direction of the machine body K is not adjusted even if the steering lever 52 is tilted left and right. You may comprise as follows. That is, while the controller CT and the controller on the main unit side are connected by a communication line and the sensor detects that the weeding device 8 and the pulling device 9 are in the raised position, the steering lever A signal is transmitted from the controller CT to the controller on the unit side so that the left and right side clutch transmission cut-off state provided in the mission case 50 is not switched even if the operation of tilting the left and right 52 is performed. Thus, the checking means is formed. That is, when the steering lever 52 is abruptly tilted due to an erroneous operation or the like in a state where the weeding device 8 and the pulling device 9 are raised at the heel and the cutting blade 10 is exposed, the aircraft body K turns rapidly. In addition, there is a risk that the cutting blade 10 or the like may be pushed into the hook and breakage, and it is also dangerous for nearby workers. However, by providing the checking means as described above, the cutting blade 10 or the like can be used as a hook. It is difficult to cause a situation where it is pushed and damaged, and safety can be improved.

また、前記コントロ−ラＣＴの入力側に牽制解除スイッチを接続し、上記のように操向レバ−５２を左右に傾倒操作しても、ミッションケ−ス５０内に設けた左右のサイドクラッチ伝動遮断状態に切り換わらないようにする前記の牽制手段を、牽制解除スイッチの操作によって牽制解除できるように構成してもよい。これにより、牽制解除した状態では、畦際で分草装置８と引起装置９を上昇させたまま、操向レバ−５２を傾倒操作して、小回りしながら、あるいは機体Ｋの向きを微妙に調節しながら、この畦際に植立する穀稈を刈り取ることができ、この畦際での刈取作業の精度および能率を向上させることができる。 Even if a check release switch is connected to the input side of the controller CT and the steering lever 52 is tilted left and right as described above, the left and right side clutch transmissions provided in the mission case 50 are transmitted. The restraining means for preventing the switching to the shut-off state may be configured so that the restraint can be released by operating the restraint release switch. As a result, in a state where the restraint is released, the steering lever 52 is tilted while the weeding device 8 and the pulling device 9 are raised at the edge, and the direction of the airframe K is finely adjusted while turning slightly. On the other hand, it is possible to mow the cereal culm planted at the heel and improve the accuracy and efficiency of the chopping work at the heel.

また、上述のように分草装置８と引起装置９を上昇させて牽制手段が牽制状態になっていても、操作スイッチＳＷ１を他方向側へ操作して分草装置８と引起装置９が元の通常の刈取作業位置へ下降復帰すると、牽制手段による牽制状態が自動的に解除されるようにコントロ−ラＣＴを設定するとよい。これにより、通常の刈取作業を再開する際に、わざわざこの牽制状態を解除操作する必要がなくなり、操作性を向上させることができる。 Moreover, even if the weeding device 8 and the pulling device 9 are raised as described above and the check means is in the check state, the operation switch SW1 is operated in the other direction side so that the weeding device 8 and the pulling device 9 are restored. The controller CT may be set so that the check state by the check means is automatically released when returning to the normal cutting operation position. Thereby, when resuming a normal cutting operation, there is no need to bother to release the restrained state, and operability can be improved.

また、機体Ｋの適所に該機体Ｋの前後傾斜姿勢を検出する前後傾斜センサを設けて該前後傾斜センサを前記コントロ−ラＣＴの入力側に接続し、前後傾斜センサが機体Ｋの前上がり傾斜を検出した場合に、コントロ−ラＣＴから電動モ−タ４０へ正転出力がなされるように構成してもよい。これにより、例えばコンバインが畦越えをする際に畦に乗り上げて前上がり傾斜になると、分草装置８と引起装置９が上昇し、この上昇に伴って重量物である分草装置８と引起装置９が前方へ移動する。これによって、機体Ｋの重心位置を前方へ移動させ、畦越え時の機体Ｋの前後傾斜姿勢の急激な変化を少なくすることができる。 Further, a front / rear tilt sensor for detecting the front / rear tilt posture of the airframe K is provided at an appropriate position of the airframe K, and the front / rear tilt sensor is connected to the input side of the controller CT. It may be configured such that the forward rotation output is made from the controller CT to the electric motor 40 when the motor is detected. As a result, for example, when the combine climbs over the reed when the combine crosses the reed and rises forward, the weeding device 8 and the pulling device 9 are lifted, and with this lift, the weeding device 8 and the pulling device that are heavy objects are raised. 9 moves forward. As a result, the center of gravity of the airframe K can be moved forward, and a sudden change in the forward / backward tilt posture of the airframe K when over the heel can be reduced.

また、前記コントロ−ラＣＴの入力側に、機体Ｋの前後傾斜姿勢を検出する前後傾斜センサと刈取クラッチの入り状態を検出するスイッチと脱穀クラッチの入り状態を検出するスイッチとを接続して、刈取クラッチと脱穀クラッチとが共に入り状態になっていることを検出している状態において、前後傾斜センサが機体Ｋの前下がり傾斜を検出すると、コントロ−ラＣＴから電動モ−タ４０に正転出力がなされるように構成してもよい。これにより、コンバインを畦越えさせた直後から穀稈を刈り取りながら圃場に侵入せねばならないような圃場であっても、分草装置８と引起装置９が上昇退避しているために、分草装置８が圃場面に突っ込んで破損するような不具合を少なくすることができる。 Further, on the input side of the controller CT, a front / rear inclination sensor for detecting the front / rear inclination posture of the machine body K, a switch for detecting the engagement state of the reaping clutch, and a switch for detecting the engagement state of the threshing clutch are connected, When it is detected that the reaping clutch and the threshing clutch are in a state of being joined together, when the front / rear tilt sensor detects the forward downward tilt of the airframe K, the controller CT forwards the motor to the electric motor 40. You may comprise so that force may be made. As a result, even in a field where it is necessary to invade the field while harvesting the cereal immediately after the combine is overgrown, the weeding device 8 and the pulling device 9 are lifted and retracted. It is possible to reduce the trouble that 8 is pushed into the field scene and is damaged.

図８に示すように、上述の実施例１のコンバインにおいて、その刈取部４への伝動機構を一部変更し、走行用のミッションケ−ス５０へ入力する静油圧式無段変速装置５３によって駆動される出力軸５４を設け、該出力軸５４と刈取出力軸５５との間にベルト変速機構５６を設け、刈取出力軸５５に設ける刈取出力プ−リ５７から刈取部４の入力プ−リ（図示省略）へベルト伝動する構成とする。そして、前記ベルト変速機構５６の変速比を変更調節する変速用電動モ−タ５８を設ける。一方、前記刈取部４の機体Ｋに対する昇降位置を検出するポテンショメ−タ５９を設ける。 As shown in FIG. 8, in the combine according to the above-described first embodiment, the transmission mechanism to the mowing unit 4 is partially changed, and the hydrostatic continuously variable transmission 53 that inputs to the traveling mission case 50 is used. An output shaft 54 to be driven is provided, a belt speed change mechanism 56 is provided between the output shaft 54 and the cutting output shaft 55, and an input pulley of the cutting unit 4 from a cutting output pulley 57 provided on the cutting output shaft 55. The belt is transmitted to (not shown). A speed changing electric motor 58 for changing and adjusting the speed ratio of the belt speed change mechanism 56 is provided. On the other hand, a potentiometer 59 for detecting the lift position of the cutting unit 4 with respect to the machine body K is provided.

そして、図９に示すように、コントロ−ラ６０に対して、その入力側に前記ポテンショメ−タ５９を接続する一方、その出力側に前記変速用電動モ−タ５８を接続する。
コンバイン作業は、分草装置８によって圃場に植立する穀稈を分草し、この分草された穀稈を引起装置９によって引起し、この引起された穀稈の株元部を刈刃１０によって切断し、この刈取穀稈を搬送装置１１によって後方へ搬送して脱穀部のフィ−ドチェン１６に引き継いで脱穀処理する。このようなコンバイン作業において、例えば圃場の一辺を刈り終えて畦際に達したときに、この畦が比較的高く、刈取部４を上昇させても分草装置８等が干渉する場合には、操縦部７からのスイッチ操作によって電動モ−タ４０を作動させて、刈取部４の上部に横向き姿勢に配置する回動軸心Ｓを支点として分草装置８と引起装置９とを一体的に上方回動させる。これにより、分草装置８や引起装置９を畦に干渉させることなく、刈刃１０を畦に接近させてこの畦際の植立穀稈を刈り取ることができる。また、この畦が比較的低い場合には、分草装置８と引起装置９とを通常の位置に保持したまま、この畦に干渉しない高さまで刈取部４全体を機体Ｋに対して上昇させる。すると、ポテンショメ−タ５９によって刈取部４の機体Ｋに対する昇降位置が検出され、この昇降位置が設定高さを越えると、コントロ−ラ６０から変速用電動モ−タ５８へ出力がなされ、該変速用電動モ−タ５８の作動によって前記ベルト変速機構５６が増速作動し、これによって刈取出力プ−リ５７の回転が増速して、刈取部４全体の駆動速度、すなわち引起装置９の引起速度と刈刃１０の駆動速度と搬送装置１１の搬送速度とが自動的に増速し、この状態で前進することによってこの畦際の植立穀稈を刈り取ることができ、この前進速度が低速であっても、引起装置９の引起速度の増速および搬送装置１１の搬送速度の増速によって植立穀稈を良好な姿勢に引起して刈り取り、良好な姿勢で搬送することができる。 Then, as shown in FIG. 9, the potentiometer 59 is connected to the input side of the controller 60, and the shifting electric motor 58 is connected to the output side thereof.
In the combine work, the cereals to be planted in the field are weeded by the weeding device 8, the weed cereals are raised by the pulling device 9, and the stock base portion of the raised cereals is cut by the cutting blade 10. The chopped cereals are transported backward by the transport device 11 and taken over by the feed chain 16 of the threshing unit for threshing. In such a combine work, for example, when the side of the field has been cut and the culm has been reached, if the culm is relatively high and the weeding device 8 or the like interferes even when the mowing unit 4 is raised, The electric motor 40 is actuated by a switch operation from the control unit 7, and the weeding device 8 and the pulling device 9 are integrally formed with the pivot axis S arranged in the horizontal posture on the upper portion of the cutting unit 4 as a fulcrum. Turn upward. Thereby, without causing the weeding device 8 and the pulling device 9 to interfere with the cocoon, the cutting blade 10 can be brought close to the cocoon and the planted cereal cocoon can be harvested. Further, when the wrinkle is relatively low, the entire cutting unit 4 is raised with respect to the machine body K to a height that does not interfere with the wrinkle while keeping the weeding device 8 and the pulling device 9 in the normal positions. Then, the potentiometer 59 detects the raising / lowering position of the cutting unit 4 with respect to the machine body K, and when this raising / lowering position exceeds the set height, an output is made from the controller 60 to the electric motor 58 for shifting, The belt transmission mechanism 56 is accelerated by the operation of the electric motor 58 for shifting, whereby the rotation of the cutting output pulley 57 is increased, so that the driving speed of the entire cutting unit 4, that is, the pulling device 9 The pulling speed, the driving speed of the cutting blade 10 and the conveying speed of the conveying device 11 are automatically increased, and by moving forward in this state, it is possible to cut the planted cereal rice cake at the edge, and this forward speed is Even at a low speed, the planted culm can be raised and cut in a good posture by the increase in the pulling speed of the pulling device 9 and the increase in the transfer speed of the transfer device 11, and can be conveyed in a good posture.

図１０に示すように、上述の実施例２のコンバインにおいて、前記引起ユニット２６の上方回動位置を検出するポテンショメ−タ６１を設け、図１１に示すように、コントロ−ラ６２に対して、その入力側に前記ポテンショメ−タ６１を接続する一方、その出力側に前記変速用電動モ−タ５８を接続する。 As shown in FIG. 10, in the combine according to the second embodiment, a potentiometer 61 for detecting the upward rotation position of the pulling unit 26 is provided, and as shown in FIG. The potentiometer 61 is connected to the input side, and the shift motor 58 is connected to the output side.

コンバイン作業は、分草装置８によって圃場に植立する穀稈を分草し、この分草された穀稈を引起装置９によって引起し、この引起された穀稈の株元部を刈刃１０によって切断し、この刈取穀稈を搬送装置１１によって後方へ搬送して脱穀部のフィ−ドチェン１６に引き継いで脱穀処理する。このようなコンバイン作業において、例えば圃場の一辺を刈り終えて畦際に達したときに、操縦部７からのスイッチ操作によって電動モ−タ４０を作動させて、刈取部４の上部に横向き姿勢に配置する回動軸心Ｓ（伝動軸４３の軸心に同じ）を支点として分草装置８と引起装置９とからなる引起ユニット２６を一体的に上方回動させる。すると、この引起ユニット２６の上方回動位置をポテンショメ−タ６１によって検出し、この上方回動位置が設定高さを越えると、コントロ−ラ６２から変速用電動モ−タ５８へ増速出力がなされ、該変速用電動モ−タ５８の作動によって前記ベルト変速機構５６が増速作動し、これによって刈取出力プ−リ５７の回転が増速して、刈取部４全体の駆動速度、すなわち引起装置９の引起速度と刈刃１０の駆動速度と搬送装置１１の搬送速度とが自動的に増速し、少なくとも搬送装置１１の搬送速度が自動的に増速するために、この状態で前進することによって、引起装置９が作用せずとも、少なくとも搬送装置１１の搬送速度の増速によって刈取穀稈を良好に取り込んで刈り取り、搬送することができる。この刈取搬送速度の増速状態を図１２のグラフに示す。Ａが通常の刈取作業状態における変速ライン、Ｂが畦際での刈取作業状態における変速ラインである。尚、この刈取搬送速度の増速状態を図１３のグラフのように設定してもよい。 In the combine work, the cereals to be planted in the field are weeded by the weeding device 8, the weed cereals are raised by the pulling device 9, and the stock base portion of the raised cereal is cut by the cutting blade 10. The chopped cereals are transported backward by the transport device 11 and taken over by the feed chain 16 of the threshing unit for threshing. In such a combine work, for example, when one side of the field is cut and the heel is reached, the electric motor 40 is operated by a switch operation from the control unit 7 so that the electric motor 40 is placed in a horizontal posture on the upper part of the cutting unit 4. The pulling unit 26 composed of the weeding device 8 and the pulling device 9 is integrally rotated upward with the rotating shaft S to be arranged (same as the shaft center of the transmission shaft 43) as a fulcrum. Then, the upward rotation position of the pulling unit 26 is detected by the potentiometer 61. When the upward rotation position exceeds the set height, the controller 62 outputs the speed increase to the transmission electric motor 58. The belt transmission mechanism 56 is accelerated by the operation of the shifting electric motor 58, whereby the rotation of the cutting output pulley 57 is increased, that is, the driving speed of the entire cutting unit 4, that is, The pulling speed of the pulling device 9, the driving speed of the cutting blade 10, and the conveying speed of the conveying device 11 are automatically increased, and at least the conveying speed of the conveying device 11 is automatically increased. By doing so, even if the pulling device 9 does not act, the harvested cereal can be satisfactorily taken, harvested and transported at least by the increase in the transport speed of the transport device 11. The graph of FIG. 12 shows the state in which the cutting conveyance speed is increased. A is a shift line in a normal cutting operation state, and B is a transmission line in a cutting operation state at the heel. In addition, you may set the acceleration state of this cutting conveyance speed like the graph of FIG.

また、脱穀装置３のフィ−ドチェン１６を変速可能に構成して、上述のようにして刈取部４全体の駆動速度が自動的に増速した場合、すなわち引起装置９の引起速度と刈刃１０の駆動速度と搬送装置１１の搬送速度とが自動的に増速した場合に、フィ−ドチェン１６の駆動速度も同調して増速するように構成してもよい。これにより、増速した搬送装置１１から送られてくる刈取穀稈をフィ−ドチェン１６に引き継いで搬送する際に、この引継ぎ部における穀稈の詰まりを防止して円滑に引継ぎ搬送することができる。 Further, when the feed chain 16 of the threshing device 3 is configured to be variable, and the driving speed of the entire cutting unit 4 is automatically increased as described above, that is, the pulling speed of the pulling device 9 and the cutting blade 10. When the drive speed of the feed chain 16 and the transport speed of the transport device 11 are automatically increased, the drive speed of the feed chain 16 may be increased in synchronization. As a result, when the harvested cereals sent from the speed-up conveying device 11 are transferred to the feed chain 16 and conveyed, the clogging of the cereals in the takeover portion can be prevented and smoothly transferred. .

更に、上述のようにして刈取部４全体の駆動速度が自動的に増速した場合、すなわち引起装置９の引起速度と刈刃１０の駆動速度と搬送装置１１の搬送速度とが自動的に増速した場合に、フィ−ドチェン１６の駆動速度が同調して増速し、且つ、供給調節モ−タを駆動して前述の扱ぎ深さ調節手段を深扱ぎ側へ自動的に調節するように構成してもよい。即ち、畦際において分草装置８と引起装置９の作用を受けずに刈り取られる穀稈は、いくぶん穂先側から刈り取られるために穀稈丈が短く、この穀稈を、畦際に至る前の通常の刈取作業時に穂先側穀稈センサ−と株元側穀稈センサ−との検出結果によって制御していた扱ぎ深さ調節状態でフィ−ドチェン１６へ引き継ぐと、浅扱ぎ状態となって脱穀装置３で適切な脱穀作用を受けることができずに収穫損失となる問題がある。しかしながら、上述のように構成することによって、畦際で刈り取った短い穀稈でも脱穀装置３へ適切な扱ぎ深さで投入して脱穀処理でき、収穫損失を少なくすることができる。 Furthermore, when the driving speed of the entire cutting unit 4 is automatically increased as described above, that is, the pulling speed of the pulling device 9, the driving speed of the cutting blade 10, and the conveying speed of the conveying device 11 are automatically increased. When the speed is increased, the drive speed of the feed chain 16 is increased synchronously, and the supply adjusting motor is driven to automatically adjust the above-mentioned handling depth adjusting means to the deep handling side. You may comprise as follows. That is, the cereal that is harvested without being affected by the weeding device 8 and the pulling device 9 at the heel is cut somewhat from the ear tip side, so that the culm length is short. When handing over to the feed chain 16 in the state of adjusting the handle depth controlled by the detection result of the tip side grain culm sensor and the stock source side culm sensor during normal cutting operation, it becomes a shallow handle state. There is a problem that the threshing device 3 cannot receive an appropriate threshing action, resulting in a harvest loss. However, by configuring as described above, even a short culm that has been harvested at the edge can be thrown into the threshing device 3 at an appropriate handling depth, and the threshing process can be reduced.

尚、刈取対象の穀稈を掻き込むラグ式の掻込ベルト１２と、該掻込ベルト１２を巻き掛ける後側のプ−リと同軸のスタ−ホイル１３とからなる搬送装置１１だけを増速可能に構成して、分草装置８と引起装置９とからなる引起ユニット２６が上昇した場合に、この掻込ベルト１２とスタ−ホイル１３とからなる搬送装置１１だけが増速して駆動されるように構成してもよい。これによって、引起装置９が上昇して植立穀稈の作用しなくなっても、増速した掻込ベルト１２とスタ−ホイル１３とによって畦際の植立穀稈を円滑に掻き込んで刈り取ることができる。 It is to be noted that only the conveying device 11 consisting of a lag type scooping belt 12 for scrambling the grain to be harvested, a rear pulley around which the scooping belt 12 is wound and a coaxial star wheel 13 is accelerated. When the pulling unit 26 composed of the weeding device 8 and the pulling device 9 is raised, only the conveying device 11 composed of the stir belt 12 and the star wheel 13 is driven at an increased speed. You may comprise. As a result, even if the pulling device 9 rises and the planted cereals do not act, the planted culm at the end is smoothly scraped and trimmed by the increased speeding belt 12 and the star wheel 13. Can do.
