これにより、前記排出筒１４内には、防止杆４１を設けたことにより、作業者が手を挿入した時であっても、危険防止することができる。又、排出筒１４を回動操作した時に、穀粒の流れを阻害することがない。 Accordingly, by providing the prevention rod 41 in the discharge cylinder 14, it is possible to prevent danger even when the operator inserts his / her hand. Moreover, when the discharge cylinder 14 is rotated, the flow of the grain is not hindered.

前記穀粒移送排出筒装置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３３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２３で示す如く前後方向に略水平状態に支持させるべくオーガ受装置３３の受主柱３３ａの全高を低くして、この受主柱３３ａの上端部には、受ガイド３３ｂを設け、この受ガイド３３ｂで略水平状態に支持させた構成である。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構成である。 To increase the overall height of the auger receiving device 33 that supports a predetermined position of the front portion of the fixing transfer cylinder 8 of the grain transfer / discharge cylinder device 6, conventionally, the discharge cylinder 14 portion should be positioned upward at a predetermined angle, The front tip portion was a high position and the rear base portion was a low position, and it was configured to be inclined at a predetermined angle. As shown in FIG. 23, the overall height of the receiving column 33a of the auger receiving device 33 is lowered so as to be supported in a substantially horizontal state in the front-rear direction, and a receiving guide 33b is provided at the upper end of the receiving column 33a. The guide 33b is supported in a substantially horizontal state. Further, 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、コンバインの収納スペースを低くすることができる構成である。 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. In addition, the storage space for the combine can be reduced.
