PROBLEM TO BE SOLVED: To solve problems such as deterioration of efficiency in unloading grains to a tank by an unloading auger and deterioration of operation efficiency and operability. SOLUTION: An auger cylinder 16 arranged at the tip of the transverse unloading auger 6 is equipped with an auger grain unloading part 10 freely rotatably in the circumferential direction of the auger cylinder 16 by a rotation mechanism 20, and the auger grain unloading part 10 is provided with an ultrasonic sensor 35. The auger grain unloading part 10 directs an unloading port 11 toward a position just under the nearly right and left center of the tank 36 at the lowest position and unloads the grains, then sways the unloading port 11 to either one of the right and the left sides to unload the grains to the one side and subsequently sways the unloading port 11 to the other of the right and the left sides and unloads the grains to the other side as one stroke. When the unloading of the one stroke is completed, the unloading port 11 is automatically lifted to a prescribed height and the swaying and unloading from the position just under the center to the right and the left sides is repeated.
