The fuel tank 15 and the air cleaner 16 are housed in the roof-shaped lower space formed by, and the fuel cage 15a and the fuel port 15b of the fuel tank 15 make it easy to check the remaining fuel amount and refuel. It is provided facing the outside of the aircraft. Reference numeral 17 is a paddy receiving floor, 18 is an overhanging subfloor, and 19 is a padded bag hanging in front of and behind the engine compartment 12. As described above, the hopper 13 is installed in the upper part of the engine room 12 so as to extend in the front-rear direction centering on the engine room 12, and the pair of hopper openings 14, 14 provided in the lower part of the front and rear ends is provided with paddy on both flow slopes 13a. Since it is dropped, the capacity is conventionally larger than that of a hopper installed in series in front of or behind the engine compartment 12. Further, since the rice bag hanging rods 19 are provided in front of and behind the engine room 12, two workers can work at the same time without hitting each other.

FIG. 2 shows an embodiment of the device for removing sediment of straw according to the present invention. The device 10 for removing sediment of straw is provided from the start end of the straw feed chain 7 to the rear end of the machine body. A front end is rotatably supported by a shaft 20 on the root side of the straw until reaching the straw processing unit 9, and an extended end on the shaft 20 side is urged by a spring 21 so that a rear free end side. Is provided with a plate-shaped hitting member 22, and the hitting member 22 is driven by the rotating shaft 23 of the handling cylinder 5a in the threshing unit 5 via the bevel gear 24 and the universal joint 25.
