[0030] When in use, by fixing the triangular plate 22 on both sides of the rotating plate 21 with bolts, the wear of the rotating plate 21 during rotation can be effectively reduced. At the same time, the triangular plate 22 can effectively and quickly guide qualified materials into the rotor, reducing the contact time with the blade 2 as a whole. After installation, the rotating plate 21 is rotatably installed between the upper mounting ring 111 and the lower mounting ring 121, and the upper rotor shaft 111 and the lower rotor shaft 121 are fixed by a flange, and then the upper rotor shaft 111 is fixed on the drive assembly for rotation.

[0031] Reference Figure 1-2 A plurality of guide plates 221 are arranged on the outer side surface of the triangular plate 22. The guide plates 221 are arranged to be tilted downward. The arrangement of the guide plates 221 can guide qualified raw materials downward so that the qualified raw materials can quickly enter the bottom for collection, and at the same time prevent larger raw materials from damaging the triangular plate 22 or the rotating plate 21.

The rotating block 32 is fixedly arranged on the top of the clamping block 31, and the clamping block 31 is slidably connected to the top of the rotating plate 21.

[0033] More specifically, the top of the rotating plate 21 is arranged in a square column;

[0034] When in use, the rotating block 32 is lifted to drive the clamping block 31 to move upward and disengage from the upper mounting ring 111. The clamping block 31 is connected to the top of the rotating plate 21, so that the rotating plate 21 can be driven to rotate at an angle. After the rotating plate 21 has rotated, the clamping block 31 is inserted into the upper mounting ring 111 for fixing. The angle of the rotating plate 21 can be adjusted and the angle of the rotating plate 21 can be fixed at the same time.
