There are at least two sieve plates 3. The sieve holes on the sieve plates 3 become smaller from top to bottom. The second discharge port 4 is provided on the side of the box body 1 and is located at the lowest point of the sieve plate 3; The support base 5 is arranged in the box body 2 and is located on the left and right sides of the sieve plate 3; The installation box 6 is arranged on the other side of the box body 1; A rotating shaft 7 is provided in the installation box 6, and the rotating shaft 7 is equipped with a power device 8; A roller 9 is provided on the rotating shaft 7, and a cam groove 10 is provided on the surface of the roller 9; One end of the connecting rod 11 is connected to the sieve plate 3 , and the other end is matched with the cam groove 10 . The connecting rod 11 and the sieve plate 3 are arranged in parallel.

[0020] The power device 8 is a motor, and the support seat 5 is used to support the two ends of the screen plate 3. The motor drives the roller 9 on the rotating shaft 7 to rotate. During the rotation of the roller 9, one end of the connecting rod 11 moves in the cam groove 10, thereby driving the connecting rod 11 to move back and forth. The connecting rod 11 drives the screen plate 3 to move back and forth, allowing stones of different specifications to be discharged from different discharge ports respectively, and the stones are effectively sorted. At the same time, the device has low operating noise and will not cause interference to the surrounding environment.

[0021] In the embodiment, Figure 1 、 Figure 2 As shown, the connecting rod 11 is provided with a roller 12 for cooperating with the cam groove 10. The roller 12 and the cam groove 10 are rolling friction, and the friction force is small, which facilitates the connecting rod 11 to move back and forth in the cam groove 10.

[0022] In the embodiment, Figure 1 、 Figure 3 As shown, the support seat 5 is provided with a guide groove 13, and the bottom of the sieve plate 3 is provided with a guide block 14 for cooperating with the guide groove 13. The guide groove 13 can be a dovetail groove to ensure the linearity of the sieve plate 3 moving back and forth without interfering with the inner wall of the box body 1.

[0023] In the embodiment, Figure 1 、 Figure 4 As shown, a connecting sleeve 15 is provided at the bottom of the sieve plate 3, and through holes 16 are provided on both sides of the connecting sleeve 15. An elastic positioning pin 17 is provided on the connecting rod 11 for cooperating with the through holes 16. The connecting rod 11 is inserted into the connecting sleeve 15, and the elastic positioning pin 17 on the connecting rod 11 cooperates with the through holes 16, making it easy to assemble and disassemble the connecting rod 11 and the sieve plate 3.

[0024] In the embodiment, Figure 1 、 Figure 5As shown, the length of the connecting rod 11 is adjustable. By adjusting the length of the connecting rod 11, the other end of the connecting rod 11 is facilitated to accurately match the cam groove 13.

[0025] In the embodiment, Figure 1 、 Figure 5 As shown, the connecting rod 11 includes a No. 1 connecting rod 18 and a No. 2 connecting rod 19, and a bidirectional threaded rod 20 is connected between the No. 1 connecting rod 18 and the No. 2 connecting rod 19. The length of the connecting rod 11 can be adjusted by rotating the bidirectional threaded rod 20, and the adjustment is convenient.

[0026] In the embodiment, Figure 1 As shown, a dust suction pipe 21 is provided above the sieve plate 3, and the dust suction pipe 21 is connected to a dust collector 22. It is used to absorb the dust in the box body 1 to prevent the dust from overflowing from the box body 1 during sorting and polluting the environment.

[0027] In the embodiment, Figure 1 As shown, staggered baffles 23 are provided below the feed port. The baffles 23 are tilted downward and hinged to the box body 1. An elastic reset member 24 is provided between the bottom of the baffle 23 and the box body 1. The elastic reset member 24 is a spring, and the baffle 23 acts as a buffer to reduce the impact force when the stone falls into the screen plate, thereby preventing damage to the screen plate 3.
