PURPOSE:To facilitate the removal of jamming, by providing a transmission shaft which is located in the cylindrical shaft of a carry-out screw for cereal grains in a tank and transmits motive power from the screw to a cereal grain carry-up unit, and by providing a clutch for stopping the drive of only the carry-out screw. CONSTITUTION:A carry-out screw 12 is provided in a tank 9 at its bottom so that the screw can be optionally driven. A thrower-type carry-up unit 13 is coupled to the downstream end of the screw 12. The end of the cylindrical shaft 12a of the carry-out screw 12 opposite the carry-up unit 13 is connected to an engine 19 through a first belt tension clutch 16 having a tension arm 16a fitted in a swingable manner to a support cylinder 15 extending from the tank 9, an intermediate shaft 17 and a transmission belt 18. The rotary shaft 13d of a thrower 13a is connected to a transmission shaft 17 through a bevel gear mechanism 20, a transmission shaft 21 provided in th cylindrical shaft 12a, and a second belt tension clutch 22 having a tension arm 22a. |
