Therefore, a simple structure for transferring the harvested cereal meal from the auxiliary conveyance device 75 to the feed chain 90 can be realized at a low cost. Furthermore, it is possible to improve the appearance by preventing the stock guide member 101 from seeing the structure inside the cutting unit 4 and the sawdust accumulated on it.

  Further, in the harvesting part 4 of the combine 1, the harvesting part 4 can be laterally rotated to the left and right sides of the machine body, and the stock guide member 101 is located on the machine body rather than the pivot point of the harvesting part 4, that is, the support shaft 21. By arranging in front of the inside, it is possible to prevent the stock guide member 101 from interfering with surrounding members when the cutting unit 4 for maintenance or the like is turned sideways to the left and right sides of the machine body. It becomes. Therefore, it is not necessary to remove the stock guide member 101 when the mowing unit 4 is rotated sideways, and can be easily rotated.

Further, in the combine , the post-auxiliary guide member 102 that guides the midway portion of the harvested cereal rice cake after delivery from the auxiliary transport device 75 to the feed chain 90 is extended from the stock guide member 101 to the threshing portion 5 side. The rear end side of the auxiliary post-guide member 102 is arranged so as to overlap with the tip guide member 108 extended from the auxiliary transport device 75 to the threshing part 5 side in plan view. After the stock base part is guided by the stock base guide member 101, it becomes possible to continuously guide the head part from the post-assisting guide member 102 to the tip guide member 108, and after delivery from the auxiliary transport device 75 to the feed chain 90. It is possible to prevent the trouble that the tip portion of the tip hits the edge of the tip guide member and the conveying posture of the harvested cereal may be disturbed. Therefore, the harvested cereal grains inherited from the auxiliary conveying device 75 to the feed chain 90 can be smoothly conveyed to the handling port 91a formed in the handling chamber 91 of the threshing unit 5 without disturbing the conveying posture.
