PROBLEM TO BE SOLVED: To increase the capacity of a grain tank by reducing the size of a discharge auger derricking drive mechanism derricking a discharge auger in the upper end of a vertically feeding auger.SOLUTION: In a grain discharge auger derricking drive mechanism for a grain tank, a connection cylinder 50 communicating a vertically feeding auger 13 and a discharge auger 14 is connected to a vertically feeding auger side connection cylinder 50a such that a discharge auger side connection cylinder 50b can vertically turn, a turning gear 41 is fixed to one of the vertically feeding auger side connection cylinder 50a and the discharge auger side connection cylinder 50b, an electric motor 43 wherein a drive gear 42 meshing with the turning gear 41 is fixed to an output shaft is installed to the other, and the discharge auger 14 is derricked by a drive force of the electric motor 43. The grain discharge auger derricking drive mechanism is provided with an uprise energizing implement (44) energizing an auger cylinder (14c) to the uprise direction. |
