<P>PROBLEM TO BE SOLVED: To compactly attach a grain unloader to a relatively small discharge pipe by devising a structure of attaching a shutter driving device to the discharge pipe. <P>SOLUTION: The grain unloader is configured to swing and open/close a shutter 46 by using an electric motor 50 for opening/closing and a rotary cam 60. The rotary cam 60 and the electric motor 50 for opening/closing are disposed in such a way that the trajectory of movement of the rotary cam 60 and the center line p2 of a motor body of the electric motor 50 for opening/closing are along a side-wall portion 44a in the vertical direction of the discharge pipe 44. A rotation center position p3 of the rotary cam 60 is inclined to one side in the lateral direction relative to the center position y1 in the lateral direction of the discharge pipe 44 in the direction along the horizontal shaft center p1 of the shutter 46, and the center line p2 of the motor body of the electric motor 50 for opening/closing is located on the opposite side from the side to which the rotary cam 60 is inclined with the center position y1 in the lateral direction of the discharge pipe 44 disposed in-between. <P>COPYRIGHT: (C)2012,JPO&INPIT |
