[0021] In use, the feedstock to be crushed is introduced into the crushing tank 1 through the inlet pipe 7, and the feedstock enters the inside of the partition cylinder 10, the first motor 8 and the air pump 5 are started, the first motor 8 drives the rotary knife mechanism 2 to rotate at high speed in the inside of the partition cylinder 10, the feedstock is sheared and crushed by the cutter, and then enters between the partition cylinder 10 and the crushing tank 1, the air is pressurized by the air pump 5 and introduced into the inside of the crushing tank 1, to drive the material that completes the crushing into the discharge mechanism 3, and the material that completes the crushing is discharged by the discharge mechanism 3 for the next process.

[0022] When the feed material is crushed, the feed material is first introduced into the inside of the partition cylinder 10, and cooperates with the rotary knife mechanism 2 through the inner guide plate 13. After the feed material is introduced, the introduced feed material is restricted by the inner guide plate 13, and the introduced feed material is prevented from freely falling. At the same time, the feed material is guided by the feature that the end of the inner guide plate 13 away from the partition cylinder 10 is inclined downward, so that the feed material falling on the top of the inner guide plate 13 slides along the inclined surface on the top to the central position, and is close to the cutter of the rotary knife mechanism 2.

In the process of rotating, the shaft cylinder 26 drives the convex strip cylinder 23 to rotate at high speed in the inside of the partition cylinder 10 through the convex strip cylinder 23.

In the process of rotating and interlacing, the feed material is sheared and crushed by the tooth edge of the tooth cutter 24.

In the process of falling, the crushing force acting on the material gradually increases, so that the material is gradually sheared and crushed. After the material is crushed and falls on the top of the conical disc 12, the bottom pad disc 27 is driven by the convex strip cylinder 23 through the fixed connection with the convex strip cylinder 23. At the same time, the bottom pad disc 27 is driven to rotate by the convex strip cylinder 23, and is restricted by the rotary fitting of the bottom rotary ring 29 and the ring groove of the conical disc 12. The bottom pad disc 27 drives the raking rod 25 to rotate by the feature that the end of the raking rod 25 away from the bottom pad disc 27 is bent downward. The crushed material is moved to the arc through slot position by the bending of the raking rod 25, and is guided out of the crushing position from the arc through slot position.

[0024] In the discharging mechanism 3, the fixed cylinder 31 connects the material guiding cylinder 32 with the crushing tank 1, so that the material which has finished crushing and sliding to the inner wall bottom of the crushing tank 1 is guided into the material guiding cylinder 32 by the fixed cylinder 31. After entering the material guiding cylinder 32, the material is rotated by the second motor 33 driving the inner rotating shaft 38, and the auger blade 37 is rotated in the material guiding cylinder 32 by the inner rotating shaft 38. When the auger blade 37 rotates, the material entering the material guiding cylinder 32 is moved to the direction of the material guiding groove 35. After reaching the material guiding groove 35, the material slides out along the material guiding groove 35 under the self-gravity and the extrusion of the subsequent material driven by the auger blade 37. At the same time, when there is liquid in the material, the liquid is concentrated at the bottom of the material guiding cylinder 32 under the action of self-gravity, and passes through the hollow plate 39 to enter the connecting groove 34 for collection.
