[0023] A through rod 17 is slidably penetrated through the box body 1 by an elastic mechanism. The through rod 17 is T-shaped. The elastic mechanism includes a spring 18 sleeved on the outside of the through rod 17. Both ends of the spring 18 are elastically connected to the outer wall of the head of the through rod 17 and the outer wall of the box body 1 respectively.

[0024] The through rod 17 is connected to the rotating shaft 15 through a transmission mechanism, which includes an upper gear 19 installed in the upper rotating groove and connected to the rotating shaft 15. The through rod 17 is provided with a rack that cooperates with the upper gear 19. The upper gear 19 is an incomplete gear. An impact block is provided on the end of the through rod 17.

[0025] When the utility model is used, the material enters the placement trough 2, enters the filter chamber 4 through the feed port 3, is filtered through the filter screen 5, smaller particles enter the second collection chamber 8, and larger particles enter the accumulation trough 6. At the same time, the drive motor 10 is started, and the drive motor 10 drives the rotating frame 11 to rotate. The filter screen 5 can be cleaned with a brush to avoid accumulation.
