transmission mesh belt 12 passes from mesh belt kiln 13 both ends, and the length of box 1 equals mesh belt kiln 13 length, and the width of box 1 slightly is less than transmission mesh belt 12 width, because transmission mesh belt 12 both sides are equipped with the support, and box 1 installs in transmission mesh belt 12 below, so in order to satisfy the installation needs, the width of box 1 slightly is less than transmission mesh belt 12 and sets up.

Furthermore, each blade 2 is connected with the box body 1 through a rotating shaft 201, the end part of each rotating shaft 201 is fixedly connected with a first rod 501, and all the first rods 501 are positioned on the same outer side of the box body 1; all the first rods 501 are hinged with the connecting rods 6;
