[0021] A connecting plate 17 is connected to one side of the concave plate 6, a groove 16 is provided in the screening machine housing 3, a first threaded rod 9 and a second threaded rod 10 are rotatably connected in the concave plate 6, an anti-slip belt 11 is drivingly connected to the outside of the second threaded rod 10, the second threaded rod 10 is connected to the first threaded rod 9 through the anti-slip belt 11, a moving plate 12 is threadedly connected to the outside of the second threaded rod 10, and a third threaded rod 13 is threadedly connected in the moving plate 12. By providing the anti-slip belt 11, when an external driver drives the second threaded rod 10 to rotate, since the second threaded rod 10 is connected to the first threaded rod 9 through the anti-slip belt 11, the first threaded rod 9 and the second threaded rod 10 can rotate synchronously, avoiding jamming when the moving plate 12 moves;

[0022] A scraper 14 is provided under the third threaded rod 13, the scraper 14 is lapped on the multi-stage screening plate 7, and the moving plate 12 is threadedly connected to the outside of the first threaded rod 9. By providing the third threaded rod 13, when the scraper 14 moves in the multi-stage screening plate 7, the height of the scraper 14 can be adjusted through the third threaded rod 13, so that the scraper 14 can easily clean different positions in the multi-stage screening plate 7, ensuring the flexibility of the screening device;

[0023] A positioning rod 18 is rotatably connected inside the groove 16. A bolt 19 is connected to the outside of the positioning rod 18. An installation groove 20 is formed inside the connecting plate 17. The bolt 19 is externally threaded with a nut 21. By providing the concave plate 6 and the installation plate 15, when the multi-stage screening plate 7 is clamped inside the screening machine housing 3, the installation plate 15 will overlap above the screening machine housing 3, and the concave plate 6 will be clamped inside the installation plate 15 after being flipped, so that the concave plate 6 and the installation plate 15 can play a certain limiting role in the position of the multi-stage screening plate 7, preventing the multi-stage screening plate 7 from falling off during vibration;

[0024] The concave plate 6 is clamped inside the installation plate 15, the bolt 19 is clamped inside the installation groove 20, the connecting plate 17 overlaps on the screening machine housing 3, and the nut 21 is clamped inside the connecting plate 17.

[0025] The working principle of the present utility model is as follows:

[0026] When the screening device screens selenium particles, the multi-stage screening plate 7 can be clamped into the screening machine housing 3, and the installation plate 15 on the surface of the multi-stage screening plate 7 will overlap above the screening machine housing 3. Then, when a turning force is applied to the concave plate 6, it will flip around the guide rod 5. After the concave plate 6 is flipped, it will be clamped inside the installation plate 15, and the connecting plate 17 on one side of the concave plate 6 will overlap above the screening machine housing 3. When a thrust is applied to the bolt 19, it will rotate around the positioning rod 18, and the bolt 19 will be clamped inside the installation groove 20. The bolt 19 is attached to the connecting plate 17 after being connected to the nut 21. After the screening of selenium particles is completed, the external drive drives the second threaded rod 10 to rotate. Since the second threaded rod 10 is connected to the first threaded rod 9 through the anti-slip belt 11, the second threaded rod 10 and the first threaded rod 9 can rotate synchronously. The moving plate 12 will move on the surfaces of the first threaded rod 9 and the second threaded rod 10, and the scraper 14 below the moving plate 12 will clean the debris on the surface of the multi-stage screening plate 7. The height of the scraper 14 can be adjusted by rotating the third threaded rod 13.
