PURPOSE:To enable a winding machine to the operated with no necessity for large power, by providing the winding machine in an upper part of a supporting machine frame, vertically provided in a bed, and extending a rail of a turning arm, which turns being erected and laid for a grain hopper, in a vertical direction along the supporting machine frame. CONSTITUTION:In the initial time of lifting action by a chain 40, the front end bottom part of a grain hopper 2 is pulled up almost in a vertical direction. And if a tractive point P of the chain 40 comes to be transferred to a connection engaging point with a turning end part of a turning arm (a), the chain 40 thereafter turns the turning arm (a) to be erected further pulled up along a rail R extended to the front surface of a supporting machine frame F. In this way, a winding machine W, by which the turning arm (a) rises turning, turns the grain hopper 2 to be tilted. Accordingly, the grain hopper 2 can be turned large tilting with no necessity for large power.
