A second material dropping groove is formed through the lower part of the side of the box body away from the first material dropping groove. Sound insulation cotton is fixedly provided around the outer walls of the base and the box body.

[0007] Furthermore, an anti-slip pad is fixedly provided at the bottom end of the base.

[0008] Furthermore, a support plate is slidably arranged inside the base. The bottom ends of the support rods all extend into the base and are fixedly connected with the top end of the support plate. A vibration motor is fixedly provided at the bottom end of the support plate.

[0009] Furthermore, a plurality of springs are fixedly provided at the bottom end of the support plate in an array. The bottom ends of the springs are all fixedly connected with the inner wall of the bottom end of the base.

The screened material will enter the cavity and then be discharged through the second blanking chute, and the remaining material will be discharged through the first blanking chute. Since a plurality of shells and screening plates are provided, the length of linear screening is increased. Therefore, the pressure on the spring can be reduced, the amplitude can be reduced, and the generation of noise can be reduced.

[0025] Specifically, Figures 1-4 As shown, a double-headed motor 17 is fixedly provided on the rear side of the box body 4, and the front output end of the double-headed motor 17 is fixedly connected to the rear end of the rotating shaft on the adjacent transmission roller 8, and the rear end of the rotating shaft on the other transmission roller 8 and the rear output end of the double-headed motor 17 are fixedly provided with a pulley 18, and the two pulleys 18 are connected by a belt 19 for transmission, and a protective cover 20 is fixedly provided on the rear side of the box body 4, and the double-headed motor 17, the pulley 18, and the belt 19 are all located in the protective cover 20, and the corresponding transmission roller 8 and the pulley 18 are driven to rotate by the double-headed motor 17, so that the other transmission roller 8 can be driven to rotate by the belt 19 and the pulley 18, and then the conveyor belt 9 can be driven to move, and the protective cover 20 can be provided to protect the double-headed motor 17, the pulley 18 and the belt 19.
