[0031] The application of one aspect of this embodiment is as follows: during use, the material is introduced into the material box 9, and the power mechanism 2 is turned on by the switch. The power mechanism 2 will drive the screen plate 8 to move left and right, and the material inside the material box 9 will fall to the upper side of the screen plate 8. The moving screen plate 8 will drive the material to shake left and right. During the shaking process, the material is screened by the screen plate 8, and larger particles will be discharged through the discharge groove 11. The screened material will be guided to the discharge pipe 7 through the conical cover 6, and then to the inside of the collection box 13 through the discharge pipe 7. When in use, the device can break up the materials that are stuck together by quickly shaking the screen plate 8, so as to avoid the materials from sticking together and being difficult to screen, thereby improving the screening efficiency.

[0032] In this embodiment, a plurality of inclined plates 19 are evenly arranged on the upper end of the sieve plate 8, and the inclined plates 19 are welded to the upper end of the sieve plate 8. The arrangement of the inclined plates 19 can cause the material to shake greatly due to inertia during the shaking of the sieve plate 8, thereby facilitating the breaking up of the material and improving the efficiency of material screening.
