PROBLEM TO BE SOLVED: To solve the problems that the rotation direction to be transmitted to a grain-raising screw of a unloading vertically grain-raising device and an unloading screw of an unloading auger is limited, the connecting metal is required to be interchanged based on the rotation direction to be transmitted, many elements are required, and assembly/production cost increases.SOLUTION: The connecting cylinder 14 includes a horizontal cylinder portion 20 connected with a grain tank 11, a vertical cylinder portion 22 connected with a grain-raising cylinder 21, an inclined part 23 of a crossing part of the vertical cylinder portion 22 with the horizontal cylinder portion 20, and a transfer screw 15 transferring grains transferred by a tank inside unloader 12 to a unloading vertical grain-raising device 18. In the connecting cylinder 14, a transmission case 25 including each of an unloading side bevel gear 27 and a grain-raising side bevel gear 30, transmitting rotation to the tank inside unloader 12, and the unloading vertical grain-raising device 18, is arranged, the transmission case 25 has a space in which position change of the unloading side bevel gear 27 to the grain-raising side bevel gear 30 can be performed so that the unloading side bevel gear 27 and the grain-raising side bevel gear 30 can transmit normal and reverse rotations. |
