これにより、前記排出筒14の移動により、操作装置21dも同時に移動することにより、作業者の位置に対して、この操作装置21dの位置を一定にでき、このために、操作性が向上する。   As a result, the operation device 21d is also moved simultaneously with the movement of the discharge cylinder 14, whereby the position of the operation device 21d can be made constant with respect to the operator's position, thereby improving the operability.

前記移送排出筒装置6の移動用移送筒13は、図21、及び図22で示すように、手動操作により、伸縮移動する。この伸縮移動を手動操作で任意位置で固定する固定装置34を、移動用移送筒13の移送始端部側へ設けている。この固定装置34は、固定支持枠34aへ回動用レバー34bを回動自在に設け、この回動用レバー34bの基部には、固定用ボス34cを設けている。この固定用ボス34cは、移動用移送筒13の外径部へ設けた挿入用孔を経て固定用移送筒8の外周部へ押圧されて、移動用移送筒13を任意の位置へ固定できる。又、回動用レバー34bを把持操作により、固定用ボス34cが固定用移送筒8の外周部への押圧が解除され、移動用移送筒13を任意の位置へ移動操作ができる。   As shown in FIGS. 21 and 22, the transfer cylinder 13 for movement of the transfer / discharge cylinder device 6 is expanded and contracted by manual operation. A fixing device 34 for fixing the expansion and contraction movement at an arbitrary position by manual operation is provided on the transfer start end side of the transfer cylinder 13 for movement. In the fixing device 34, a rotation lever 34b is rotatably provided on the fixed support frame 34a, and a fixing boss 34c is provided at the base of the rotation lever 34b. The fixing boss 34c is pressed to the outer peripheral portion of the fixing transfer cylinder 8 through an insertion hole provided in the outer diameter portion of the moving transfer cylinder 13, and can fix the moving transfer cylinder 13 to an arbitrary position. Further, by holding the turning lever 34b, the fixing boss 34c is released from the outer peripheral portion of the fixing transfer cylinder 8, and the moving transfer cylinder 13 can be moved to an arbitrary position.

前記移動用移送筒13の前部の排出筒14の前側板14cの外側面には、図21、及び図22で示すように、回動装置17と、ブレーキ装置18とを設けて、この排出筒14を左側、又は右側の任意へ回動移動、及び固定できる。この回動装置17と、ブレーキ装置18との作用、及び構成は、図1、及び図2と同じである。   As shown in FIGS. 21 and 22, a rotating device 17 and a brake device 18 are provided on the outer surface of the front side plate 14 c of the discharge tube 14 at the front of the transfer tube 13. The cylinder 14 can be rotated and fixed to the left side or the right side. The operation and configuration of the rotating device 17 and the brake device 18 are the same as those in FIGS. 1 and 2.

前記固定装置34の回動用レバー34bと、ブレーキ装置18のブレーキ軸18aの外端部とは、ワイヤ36で接続している。この回動用レバー34bの把持操作により、固定装置34の固定用ボス34cの固定解除と、ブレーキ装置18のブレーキ具18cのブレーキ荷重とが、同時に行われて、移動用移送筒13の伸縮移動操作と、排出筒14の回動移動操作とを、同時に行うことができる。   The rotation lever 34 b of the fixing device 34 and the outer end portion of the brake shaft 18 a of the brake device 18 are connected by a wire 36. By the gripping operation of the turning lever 34b, the fixing release of the fixing boss 34c of the fixing device 34 and the brake load of the brake device 18c of the brake device 18 are simultaneously performed, and the telescopic movement operation of the moving transfer cylinder 13 is performed. And the rotational movement operation of the discharge cylinder 14 can be performed simultaneously.

これにより、前記回動用レバー34b一個の操作で、伸縮移動と、回動移動とが行えることにより、操作性が向上する。
前記エンジン21cの回転動力は、図20で示すように、このエンジン21cへ軸支したエンジンプーリ33aと、タンク移送螺旋4dへ軸支したタンクプーリ4eとにベルト33bを掛け渡して伝動する。このベルト33bには排出クラッチ装置26bをテンションモータ26aのモータ軸26cへ軸支して設ける。
Thus, the operability is improved by performing the expansion and contraction movement and the rotation movement by one operation of the rotation lever 34b.
As shown in FIG. 20, the rotational power of the engine 21c is transmitted across a belt 33b between an engine pulley 33a pivotally supported on the engine 21c and a tank pulley 4e pivotally supported on the tank transfer spiral 4d. The belt 33b is provided with a discharge clutch device 26b that is pivotally supported on the motor shaft 26c of the tension motor 26a.

前記排出スイッチレバー25aの「入」操作により、排出クラッチ装置26bが、テンションモータ26aで回動されて「入」状態となり、ベルト33bが張状態に作動され、エンジン21cの回転動力がタンク移送螺旋4dへ入力され、このタンク移送螺旋4d、移送排出筒装置6の各螺旋5a,7、及び移動螺旋軸9の後・中・前移動移送螺旋10,12,11等の穀粒を機外へ排出する排出経路の部品が回転駆動される構成である。又、排出スイッチレバー25aの「切」操作により、エンジン21cの回転駆動は、入力されなくなる。   By the "ON" operation of the discharge switch lever 25a, the discharge clutch device 26b is rotated by the tension motor 26a to be in the "ON" state, the belt 33b is operated in the tensioned state, and the rotational power of the engine 21c is supplied to the tank transfer spiral. 4d, and the grains such as the tank transfer spiral 4d, the spirals 5a and 7 of the transfer and discharge cylinder device 6, and the rear, middle, and front transfer spirals 10, 12, and 11 of the moving spiral shaft 9 are taken out of the machine. In this configuration, the parts of the discharge path for discharging are driven to rotate. Further, the rotation drive of the engine 21c is not input by the "turning off" operation of the discharge switch lever 25a.

前記移送排出筒装置6の固定用移送筒8の前方部の所定位置を支持するオーガ受装置35の全高を高くして、従来は排出筒14部が所定角度で上方へ位置すべく、前方の先端部を高所位置とし、後方基部を低所位置として、所定角度に傾斜させて設けた構成であったが、これをこの排出筒14部が回動移動する構成としたことにより、図8で示すように、前後方向に略水平状態に支持させるべくオーガ受装置35の受主柱35aの全高を低くして、この受主柱35aの上端部には、受ガイド35bを設け、この受ガイド35bで略水平状態に支持させる。又、これら固定用移送筒8と移動用移送筒13の地上高を低くしたことにより、コンバイン1の収納スペースを低くすることができる。   The overall height of the auger receiving device 35 that supports a predetermined position of the front portion of the fixing transfer tube 8 of the transfer discharge tube device 6 is increased, and conventionally, the discharge tube 14 portion is positioned forward at a predetermined angle so The tip portion is set at a high position and the rear base portion is set at a low position, and is tilted at a predetermined angle. As shown in the figure, the overall height of the receiving column 35a of the auger receiving device 35 is lowered to support it in a substantially horizontal state in the front-rear direction, and a receiving guide 35b is provided at the upper end of the receiving column 35a. The guide 35b is supported in a substantially horizontal state. Moreover, the storage space for the combine 1 can be reduced by lowering the ground clearance of the fixing transfer cylinder 8 and the transfer transfer cylinder 13.

前記穀粒移送排出筒装置6の固定用移送筒8、及び移動用移送筒13は、最下端位置を略水平状態に下降制御されることにより、操作が簡単である。又、コンバイン1の収納スペースを低くすることができる。   The fixing transfer cylinder 8 and the movement transfer cylinder 13 of the grain transfer / discharge cylinder device 6 are controlled easily by lowering the bottom end position to a substantially horizontal state. Moreover, the storage space of the combine 1 can be made low.
