HOPPER DEVICE

PROBLEM TO BE SOLVED: To provide a hopper device turning right and left lateral hopper wings in the direction of rise independently from each other on the right and left sides. SOLUTION: In this hopper device, both of front side end parts 22a, 22b of a hopper front apron and the right and left lateral hopper wings corresponding to both of front side end parts 22a, 22b are mutually connected by chains 23, 24, respectively, and a front end side of the hopper front apron 21 is made to rise and turn in the interlocking relationship with rise and turn of the right and left lateral hopper wings. The front side end parts 22a, 22b of the hopper front apron 21 and the chains 23, 24 are mutually connected through a long hole 25 extended in the vertical direction and an engaging piece 26 engaged slidably in the long hole 25. Length of the long hole 25 is set to such a size that the lateral hopper wing on one side can rise and turn by causing the hopper front apron to rise and turn in synchronization while the lateral hopper wing on the other side is held at a descent position.
