On the other hand, the grain tip is transferred from the rear tip transport device 38 to the threshing section supply port by the handling depth sensor 53 so that the tip is detected and transported to a predetermined position at the threshing inlet (supply port). The tip guide 52 arranged in the support frame 51 suppresses the tip lift, and even if a large amount of cereal is supplied, it stays at the threshing section supply port 4a in FIG. It will be delivered smoothly to the threshing section. The tip guide 52 can be sent to the supply port while being held down to the extent that it does not damage the culm even if the amount of cereals transported is increased, while the tip of the culm is lightly pressed during normal transport. it can.

[0028] As described above, the tip guide 52 guides the tip portion of the transporting culm to improve the lifting force ^ of the culm tip, thereby preventing the cereal from staying and clogging at the threshing section supply port. Can be prevented. The tip guide 52 and its mounting method are simple in structure, and since the support support frame 51 of the tip guide also serves as the support frame of the handling depth sensor 53, the member is worn or deformed. It can be easily replaced and installed at any time, and the cost can be kept low.
