A gear ring 8 is provided on the side of the limiting ring 7. Four interconnected tool rods 9 are fixed on the inner wall of the gear ring 8.

[0028] See also Figure 3-Figure 7A support 10 is fixedly installed on the top of the fixed ring 6. A gear 11 meshing with the ring gear 8 is rotatably installed inside the support 10. The axis of the gear 11 is fixedly connected to the output end of the drive motor 12. An extrusion filter plate 13 is provided between the ring gear 8 and the flange 3. The drive motor 12 drives the gear 11 to rotate, and the gear 11 can drive the ring gear 8 and the cutter bar 9 to rotate. The cutter bar 9 is attached to the surface of the extrusion filter plate 13 and rotates and cuts.

[0029] See also Figure 3-Figure 7 , blades are fixedly installed on both sides of the knife rod 9, and the blades fit the surface of the extrusion filter plate 13. The surface of the extrusion filter plate 13 is provided with four groups of annular filter holes. The knife rod 9 is set in an inclined shape, and the inclination direction of the knife rod 9 is just located in the gap between two adjacent filter holes on the surface of the extrusion filter plate 13, ensuring that when the knife rod 9 is not rotating, the position of the knife rod 9 will not block the filter holes on the surface of the extrusion filter plate 13.

[0030] See also Figure 3-Figure 7 The outer side of the fixed ring 6 is provided with a through hole 14 corresponding to the gear 11. The gear 11 is inserted into the through hole 14 and extends to the position outside the gear ring 8.
