[0032] Cam 6, cam 6 is mounted on the box body 1 through a rotating shaft 7, and the outer edge of cam 6 is in intermittent contact with the lower end surface of the material stripping plate 4;

[0033] A dispersing rod 8 is provided on the box body 1 and a rotating shaft 2 9 is installed. There are several dispersing rods 8, and several dispersing rods 8 are evenly distributed on the rotating shaft 2 9.
