制御部40からは、電動モータ12に回転制御信号が出力し、発電機モータ10にオン・オフ信号が出力し、フィードチェン5fと穀稈掻込移送装置23の駆動力伝動部に設ける電磁クラッチにオン・オフ信号が出力する。   From the control unit 40, a rotation control signal is output to the electric motor 12, an on / off signal is output to the generator motor 10, and an electromagnetic clutch provided in the driving force transmission unit of the feed chain 5f and the cereal scraping transfer device 23 An on / off signal is output to the.

そして、制御部40での自動制御が次のように行われる。
刈取作業中に旋回や後進のために、操作装置8aに設ける刈取装置4の昇降レバーを上昇操作すると、発電機モータ10にオン信号が出力されて刈取装置4が上昇すると共に、フィードチェン5fと穀稈掻込移送装置23の駆動が切られて停止し、電動モータ12が停止して扱胴軸5cの駆動或いは駆動アシストが停止される。
And the automatic control in the control part 40 is performed as follows.
When the raising / lowering lever of the cutting device 4 provided in the operation device 8a is operated for turning or reverse during the cutting operation, an ON signal is output to the generator motor 10 to raise the cutting device 4, and the feed chain 5f The drive of the grain kneading transfer device 23 is cut and stopped, the electric motor 12 is stopped, and the driving or driving assist of the handling cylinder shaft 5c is stopped.

なお、電動モータ12の回転を完全に停止することなく、例えば1/3程度に減速するだけでも良い。
また、この刈取装置4の上昇中に穀稈センサ4dが穀稈を感知すると、電動モータ12の回転を1/3程度に減速し、穀稈センサ4dが穀稈を感知しなくなると電動モータ12を停止するようにしても良い。
The rotation of the electric motor 12 may be simply reduced to about 1/3 without completely stopping.
Further, when the culm sensor 4d senses the cereal while the reaping device 4 is rising, the rotation of the electric motor 12 is reduced to about 3, and when the cereal sensor 4d stops sensing the cereal, the electric motor 12 is stopped. May be stopped.

さらに、前記の場合に脱穀装置5の脱穀済穀稈排出経路に拝稈センサを設け、穀稈センサ4dか拝稈センサが穀稈を感知しない状態で電動モータ12を減速し、穀稈センサ4dと拝稈センサが穀稈を検出しなくなる状態で電動モータ12を停止するようにすると、脱穀装置5からの確実な穀稈排出でフィードチェン5fと穀稈掻込移送装置23の両方を停止出来る。なお、フィードチェン5fと穀稈掻込移送装置23の両方を停止したり電動モータ12を減速したりするのは、後進時のみでも良い。   Further, in the above case, a worship sensor is provided in the threshed culm discharge path of the threshing device 5, and the electric motor 12 is decelerated in a state where the culm sensor 4d or the worship sensor does not sense the culm, and the culm sensor 4d If the electric motor 12 is stopped in a state where the worship sensor does not detect the cereal, both the feed chain 5f and the cereal scraping and transferring device 23 can be stopped by reliable cereal discharge from the threshing device 5. . It should be noted that both the feed chain 5f and the cereal scraping transfer device 23 may be stopped or the electric motor 12 may be decelerated only during reverse travel.

操作装置8aの一つとして扱胴逆回転スイッチ41を設けている。この扱胴逆回転スイッチ41は、扱胴カバー37が開かれ駐車ブレーキが作用している際(すなわち、扱胴カバーセンサ37aが扱胴カバー37の開放を検出し駐車ブレーキセンサ38aが駐車ブレーキ作動を検出している際)に、スイッチを押し続けてオンしている間だけ電動モータ12を逆駆動して扱胴5bが低速で逆回転するか、スイッチをオンすると扱胴5bが一回転だけ逆回転するか、スイッチをオンすると扱胴5bが5秒間だけ逆回転する。   A barrel reverse rotation switch 41 is provided as one of the operation devices 8a. This barrel reverse rotation switch 41 is operated when the barrel cover 37 is opened and the parking brake is applied (that is, the barrel cover sensor 37a detects the opening of the barrel cover 37 and the parking brake sensor 38a operates the parking brake). When the switch is turned on, the electric cylinder 12 is reversely driven only while the switch is turned on to reversely rotate the handle cylinder 5b at a low speed, or when the switch is turned on, the handle cylinder 5b is rotated only once. When rotating reversely or turning on the switch, the handling cylinder 5b rotates reversely for 5 seconds.

この扱胴5bの逆回転の際に、操縦部8に設けるモニタ42に、「駐車ブレーキをかけ、扱胴カバーを開けて下さい。」と表示し、スピーカー43から「扱胴が回ります。」と発声を繰り返す。或いは、「扱胴が回ります。」と1回発声があった2秒後に扱胴5bを逆回転する。   During reverse rotation of the barrel 5b, the monitor 42 provided in the control unit 8 displays "Please apply the parking brake and open the barrel cover." And repeat the utterance. Alternatively, the handling cylinder 5b is rotated in the reverse direction 2 seconds after the utterance of “The handling cylinder rotates.”

そして、扱胴カバー37を開いたままで扱胴5bを正回転しようとすると、「扱胴カバーを閉めて下さい。」とモニタ42に表示して、扱胴カバー37を閉じるまで扱胴5bを駆動しない。   If the barrel 5b is rotated forward with the barrel cover 37 open, the monitor 42 displays "Please close the barrel cover" and the barrel 5b is driven until the barrel cover 37 is closed. do not do.

扱胴5bの駆動をエンジン7aの出力と電動モータ12の出力で行っている場合には、扱胴過負荷検出装置44を設け、エンジン7aの出力を電動モータ12の出力でアシストする。扱胴過負荷検出装置44は、扱胴軸5cの回転を検出する扱胴回転センサとエンジン7a側から扱胴駆動プーリ5eへ出力する扱胴駆動プーリ側の駆動回転センサの回転を比較して扱胴回転センサの回転が駆動回転センサの回転より低くなると過負荷状態として電動モータ12を駆動してアシストするようにする。   When the handling cylinder 5b is driven by the output of the engine 7a and the output of the electric motor 12, a handling cylinder overload detection device 44 is provided to assist the output of the engine 7a with the output of the electric motor 12. The cylinder overload detection device 44 compares the rotation of the cylinder rotation sensor that detects the rotation of the cylinder shaft 5c and the rotation of the drive rotation sensor on the cylinder drive pulley output from the engine 7a side to the cylinder drive pulley 5e. When the rotation of the barrel rotation sensor becomes lower than the rotation of the drive rotation sensor, the electric motor 12 is driven to assist as an overload state.

扱胴5bの駆動だけでなく、コンバインの全体回転部の駆動を過負荷検出装置で検出して電動モータで駆動をアシストするようにした場合に、過負荷が短時間の場合や短時間の過負荷が繰り返される場合には、穀粒や穀稈の一時的な詰まりの可能性があるので、電動モータによるアシストをしない。   When the overload detection device detects the drive of the entire rotating part of the combine as well as the drive of the handling cylinder 5b and assists the drive with the electric motor, the overload is short-time or short-time overload. When the load is repeated, there is a possibility of temporary clogging of grains and cereals, so no assistance is provided by an electric motor.
