[0033] The rotating assembly includes a side plate 14, which is fixedly connected to the side of the second connecting block 10. A worm gear 15 is rotatably connected inside the side plate 14, and a worm wheel 17 is meshed with the outside of the worm gear 15. One end of a connecting frame 8 passes through the second connecting block 10 and is fixedly connected to the worm wheel 17. The impurity removal assembly includes a fixed frame 18, which is fixedly connected to the side of the filter plate 9.
