Was transferred to the stock source transfer device 22
And, the stalks are transferred to the grain culm feeding device 67 on the side of the threshing chamber 66 by the tip transfer device 23, and are supplied to the threshing chamber 66 by the grain culm feeding device 67 and threshed.

However, when the upper joint member 33 is moved upward, the connection between the upper split transmission shaft 30 on the downward transmission cylinder 25 side and the intermediate split transmission shaft 31 on the front lower tip end conveying device 21 side is disconnected, and the lower joint. When the member 34 is moved upward,
The connection between the intermediate split transmission shaft 31 and the lower split transmission shaft 32 is disconnected, and in this state, the case 3 of the front upper tip transfer device 20
6, the support member 41 is removed, and the front lower tip transfer device 21
When the case 43 is removed from the bolt 42 fixed to the lower mounting barrel 29, the front lower tip transporting device 21 can be removed while leaving the front upper tip transporting device 20 and the lower mounting barrel 29.
Therefore, a wide space is formed between the front upper tip transporting device 20 and the front stock source transporting device 18, and maintenance can be easily performed.

In the second embodiment shown in FIG. 6, the joint member 51 is moved downward to disconnect the upper split transmission shaft 30 on the side of the downward transmission cylinder 25 and the shaft 50 of the front-side upper tip transporting device 20 from the upper side. The joint member 33 is moved upward to disconnect the shaft 50 and the intermediate split transmission shaft 31 from each other, and the case 36 of the front upper tip conveying device 20 is supported by the support member 41 of the intermediate mounting cylinder 28.
When removed from the front side, the front upper tip transfer device 20 can be removed. Next, the joint member 53 between the intermediate split transmission shaft 31 in the intermediate mounting cylinder 28 and the shaft shaft 52 for fixing the drive gear 44 of the front lower tip transfer device 21 is moved upward to move the shaft 52 and the front stock carrier. The lower joint member 34 between the lower split transmission shaft 32 on the device 18 side is moved upward to move the front lower tip transfer device 2
When the case 43 of No. 1 is removed from the support member 46, the front lower tip transfer device 21 can be removed from the mounting frame 38. It is also possible to remove only the front lower tip transfer device 21 with the front upper tip transfer device 20 attached.
