When the material falls, it will first pass through the blocking plate 7, and the blocking plate 7 will preliminarily intercept the material to reduce the falling speed of the material to prevent large particles from directly falling into the shell 2 and damaging the structure inside the shell 2.

[0022] The driving unit 9 includes a hydraulic rod 10, a connecting rod 11 and a vertical rod 12. Two hydraulic rods 10 are provided.

Before the material falls into the roller screen 3, the material passes through the material blocking plate 7. By adjusting the rotation angle of the two material blocking plates 7, the material feed amount per unit time in the roller screen 3 can be adjusted, thereby avoiding a large amount of material from pouring into the roller screen 3 in a short period of time, which affects the normal screening of the roller screen 3.

After the material is screened by the roller screen 3, the material with a smaller particle size is passed through the sieve wheel 25. The gap falls into the receiving box 13, and the particles with large particle size are transported to the receiving box 2 14 through the sieve wheel 25 and the rotating roller 24 to realize the screening of the material.

The rotating rod 21 slidingly arranged in the slide groove opened at the other end of the swing rod 20 then slides in the slide groove, and at the same time drives the rack 22 to slide relative to the receiving box 2 14. The rack 22 drives the gear 17 meshing with the rack 22 to rotate, and the gear 17 drives the rotating shaft 16 and the baffle 15 fixedly connected to the rotating shaft 16 to rotate. The specific position of the discharge is controlled by adjusting the angle of the baffle 15. When a number of sub-packaging boxes are placed in the receiving box 2 14, the position of the discharge can be adjusted by adjusting the angle of the baffle 15 to realize sub-packaging.
