[0034] Embodiment III

[0035] As Figure 1 、 Figure 2 Figure 5 shown, a kind of impurity separation device proposed by the present utility model. Compared with Embodiment II, the detailed structure of the impurity removal assembly is recorded in this embodiment. The impurity removal assembly includes support feet 18, elastic members 19, vibration motors 20, and auxiliary components. There are multiple support feet 18 evenly distributed along the length direction of the moving mesh plate 6. The support feet 18 are connected to the separation box 1. The number of elastic members 19 corresponds to that of the support feet 18, and the elastic members 19 are connected to the support feet 18. One end of the elastic member 19 is connected to the moving mesh plate 6. The elastic member 19 is selected from but not limited to a gas spring. There are two vibration motors 20 arranged symmetrically, and the vibration motors 20 are connected to the lower end surface of the moving mesh plate 6.

[0036] The auxiliary component includes beaters 21, drive devices 22, and partition plates 23. There are two beaters 21 arranged in parallel. Both ends of the beaters 21 are rotatably connected to the separation box 1 through bearings. The number of drive devices 22 corresponds to that of the beaters 21.

When negative pressure is generated by pumping air through an external air extraction device, the negative pressure attracts the dust impurities and cotton debris on the moving mesh plate 6 into the air inlet funnel 10. The cotton debris will be blocked by the second filter mesh plate 12. After the telescopic device 16 is started, its telescopic end will move to drive the cleaning plate 17 to remove the debris on the second filter mesh plate 12 to prevent it from being blocked. The impurities of cotton at different positions are separated by the reciprocating movement of the air inlet funnel 10. With the vibration of the moving mesh plate 6, the cotton will gradually move towards the discharge port 3 through the inclined surface of the moving mesh plate 6 and be discharged.

Various changes can be made without departing from the spirit of the present utility model within the scope of knowledge possessed by those skilled in the art to which it pertains.
