A sieve plate 9 that can slide up and down is arranged inside the shell 1. The sieve plate 9 is tilted inside the shell 1, and waste particles that meet the specifications fall to the bottom of the shell 1 through the sieve holes of the sieve plate 9. Two push rods 10 are fixedly connected to the lower end of the sieve plate 9, and the lower end surfaces of the two push rods 10 are both arc surfaces. Two fixed plates 11 are fixedly connected to the inner wall of the shell 1, and the lower ends of the two push rods 10 penetrate the corresponding fixed plates 11. , springs 12 are sleeved on the two push rods 10, one end of the two springs 12 is fixedly connected to the lower end of the sieve plate 9, and the other end is fixedly connected to the upper end of the corresponding fixed plate 11. A rotating shaft 13 is rotatably connected to the inner wall of one side of the shell 1, and two cams 14 are fixedly connected to the rotating shaft 13. The two cams 14 are in contact with the lower ends of the corresponding push rods 10. By setting structures such as the push rods 10, springs 12 and cams 14, during the rotation of the two cams 14, the two push rods 10 move up and down with the rotation, thereby causing the sieve plate 9 to shake up and down, thereby accelerating the screening efficiency of the waste.

[0024] Among them, a reciprocating screw 15 is rotatably connected between the inner walls of both sides of the shell 1, and a strip plate 16 is threadedly connected to the reciprocating screw 15. The strip plate 16 is slidably connected to the inner wall of the shell 1, and a plurality of connecting rods 17 are fixedly connected to the lower end of the strip plate 16. The strip plate 16 is also in an inclined state and cooperates with the sieve plate 9. The plurality of connecting rods 17 can dredge a corresponding row of sieve holes on the sieve plate 9. By reciprocating the plurality of connecting rods 17, all the sieve holes on the sieve plate 9 are dredged to prevent the waste particles from clogging the sieve holes of the sieve plate 9 and affecting the screening effect. 1 is installed with a second motor 18 on the outer wall thereof, the output shaft end of the second motor 18 extends to the inside of the housing 1 and is fixedly connected to one end of the reciprocating screw 15, one end of the rotating shaft 13 passes through the housing 1 and extends to the outside, the part of the rotating shaft 13 located outside is connected to the output shaft part of the second motor 18 through a transmission structure, and the transmission structure includes two transmission wheels 19, which are respectively installed on the part of the rotating shaft 13 located outside and the output shaft part of the second motor 18, and the two transmission wheels 19 are connected through a belt 20.

In the transmission relationship between the transmission wheel 19 and the belt 20, the second motor 18 starts and drives the rotating shaft 13 to rotate, and then drives the two cams 14 to rotate. During the rotation, when the two cams 14 contact the corresponding push rods 10, the sieve plate 9 will be pushed up, and when the two cams 14 are separated from the corresponding push rods 10, the sieve plate 9 will move down under the elastic action of the two springs 12. In this way, the two push rods 10 move up and down with the rotation of the corresponding cams 14, so that the sieve plate 9 shakes up and down to screen the crushed waste. Waste particles that meet the specifications of the sieve plate 9 will fall to the bottom of the shell 1, and waste particles that do not meet the specifications of the sieve plate 9 will fall into the collection box outside the shell 1 through the discharge port 4.
