The central bin 5 is arranged between the screening bin 3 and the flushing bin 4. A bearing is arranged at the bottom of the central bin 5. The driven shaft 6 is sleeved in the bearing. Extension plates 14 are fixed to the outer sides of the driven shaft 6 near both ends by screws. The top of the extension plate 14 is installed with a screen 15 through an installation groove. A water inlet pipe 23 is provided on one side of the top of the flushing bin 4 through a reserved hole, and a multi-way valve 21 is connected to the bottom of the water inlet pipe 23. One end of the multi-way valve 21 is connected to the inner wall of the flushing bin 4 through screws, and a nozzle 22 is provided at the bottom of the multi-way valve 21. The nozzle 22 is located at the upper end of one group of the sieves 15. A booster pump 24 is provided on the water inlet pipe 23, and a vibration motor 28 is installed on one side of the bottom end of the screening bin 3 through bolts. A vibration structure 2 is provided between the bottom of the screening bin 3 and the flushing bin 4 and the base 1.

[0020] The vibration structure 2 is composed of a pad 26 , a fixing column 25 and a cylindrical spring 27 , and the cylindrical spring 27 is arranged between the fixing column 25 and the pad 26 .

[0021] In this embodiment, Figure 1 and Figure 3 As shown, the screening chamber 3 and the flushing chamber 4 can be vibrated by means of the cylindrical spring 27 .

[0022] Wherein, a drainage pipe 19 is provided at one end of the screening bin 3 and the flushing bin 4 near the bottom through a reserved hole, and a stop valve 20 is provided on the drainage pipe 19 .

[0023] In this embodiment, Figure 1 As shown, the stop valve 20 is opened to facilitate the discharge of the liquid in the screening bin 3 and the flushing bin 4 through the drain pipe 19.

[0024] A servo motor 9 is installed on the top of the flushing bin 4 through a mounting frame 8. The power output end of the servo motor 9 is connected to a driving bevel gear 10. A driven bevel gear 7 is arranged on the periphery of the top end of the driven shaft 6. The driving bevel gear 10 is meshed with the driven bevel gear 7.
