[0019] A feeding port 9 is arranged above the crushing box 1, and the preliminary crushing mechanism includes a crushing roller 10, a crushing knife seat 11 and a crushing motor 12. The crushing roller 10 is arranged on a symmetrical rotating shaft below the dust suction port 6 in the crushing box 1, and the crushing knife seats 11 are distributed on the crushing roller 10 and on the side wall of the crushing box 1. A crushing motor 12 is installed on the outside of the crushing box 1, and the output end of the crushing motor 12 is connected with the crushing roller 10 for transmission. Meshing gears are arranged at the ends of the two groups of crushing rollers extending out of the crushing box. The crushing motor is connected with one group of crushing rollers for transmission, and the other group of crushing rollers is driven and rotated through the meshing gears.
