Preferably, recesses 13 with outward opening are arranged on the stator shell, so that the recesses 13 are clamped into fixing tools or dismounting tools. Preferably, the bottom surface of the recess 13 is a square plane, and the side wall of the recess is a sector surface. Preferably, there are four recesses, and the four recesses are arranged in one-to-one correspondence with the first through holes.

The main shaft 6 is inserted into the shaft hole, the top of the rotor shaft is provided with a pressing plate, a positioning bolt hole is arranged on the pressing plate, and the positioning bolt passes through the pressing plate and is connected with the main shaft 6. The rotor further comprises a safety device which is sleeved on the positioning bolt, the safety device is provided with a first flange which extends upward and abuts against the nut of the positioning bolt, and the safety device is provided with a second flange which extends downward and extends into the strip-shaped groove 23 after passing through the pressing plate. Thus, the rotor shaft can rotate with the main shaft 6 in two directions by using the safety device. A gap is arranged between the stator shell and the longest blade, and the gap is not greater than 4 mm. The material enters the stator shell from the first through hole, is thrown to the stator shell under the shearing of the rotor blade, and flows out from the lower part of the stator shell. Preferably, the blade is composed of a shoulder 21 in the horizontal direction and a helical surface 22 in the vertical direction, the lengths of the shoulders 21 of the blades are the same, and the lengths of the helical surfaces 22 of the blades gradually increase counterclockwise.

Further preferably, an outwardly opening annular groove is arranged outside the stator seat wall, and a steel wire rope is sleeved in the annular groove. Thus, the material thrown out at the waist hole is cut by the steel wire rope, the shearing effect is further improved, and the strength of the stator seat wall is increased by using the steel wire rope. Preferably, the inner diameter of the stator seat wall is smaller than the maximum inner diameter of the stator shell, so as to limit the position of the rotor by using the stator seat wall. Preferably, the upper opening of the stator seat wall is trumpet-shaped, and the inner diameter gradually decreases from top to bottom. Thus, the flow direction of the material is guided.
