A first tearing blade 52 is fixed on the outside of the drive shaft 51, and two first shredding blades 53 are fixed on the first tearing blade 52. A second tearing blade 55 is fixed on the outside of the bushing 54, and two second shredding blades 56 are fixed on the side wall of the second tearing blade 55. The drive shaft 51 and the bushing 54 are connected by gear transmission.

[0040] The outer casing 20 of the machine body has a feeding chamber 21, a pressing and mounting chamber 22 and a tearing and crushing chamber 23 arranged sequentially from left to right. A transmission cover 24 is fixed on the right side of the outer casing 20 of the machine body. A filter drum 28 is fixed in the pressing and mounting chamber 22. The feeding chamber 21 and the tearing and crushing chamber 23 are both in communication with the inner cavity of the filter drum 28.

[0041] The upper side of the outer casing 20 is provided with a feed inlet 25 corresponding to the feeding chamber 21. The lower right side of the outer casing 20 is provided with a discharge outlet 26 corresponding to the tearing and crushing chamber 23. The lower side of the outer casing 20 is provided with a discharge outlet 27 corresponding to the extrusion mounting chamber 22.

[0042] The spiral shaft 30 includes a transport shaft section 31 and an extrusion shaft section 32, wherein the extrusion shaft section 32 and the transport shaft section 31 are integrally formed.

The left end of the transport shaft section 31 rotates through the left side wall of the outer casing 20 and extends out of the material conveying chamber 21. The extrusion shaft section 32 is nested inside the filter drum 28. The shaft diameter of the extrusion shaft section 32 increases sequentially from left to right.

[0052] The transmission shaft 51 is nested in the tearing and crushing cavity 23, the transmission shaft 51 is fixedly connected with the extrusion shaft section 32, one end of the transmission shaft 51 away from the extrusion shaft section 32 rotates to extend to the transmission cover 24 through the right side wall of the tearing and crushing cavity 23, and a first bevel gear 57 is fixedly sleeved on one end of the transmission shaft 51 in the transmission cover 24;

[0053] Both ends of the shaft sleeve pipe 54 are connected with the transmission shaft 51 through bearings, one end of the shaft sleeve pipe 54 away from the extrusion shaft section 32 rotates to extend to the transmission cover 24 through the right side wall of the tearing and crushing cavity 23, and a second bevel gear 58 is fixedly sleeved on one end of the shaft sleeve pipe 54 in the transmission cover 24;
