Figure 1 and attached Figure 2 It can be seen that the connecting piece is a butterfly-shaped locking nut) and is movably connected to the top open end of the crushing chamber 2. A feed port 4 is provided on the top of the cover body 3, and a discharge port 5 is provided at the bottom of the crushing chamber 2.

[0041] Specifically, the shredding assembly includes a rotating shaft 6, which passes through the side wall of the crushing chamber 2 and maintains a rotation connection and maintains one end extending to the outside of the crushing chamber 2;

[0042] The transmission wheel 7 is arranged on the rotating shaft 6 outside the grinding chamber 2, so as to be connected to the external driving motor to realize transmission, driving the rotating shaft to rotate and cut the medicinal materials;

[0043] Several cutters 11 are evenly spaced and mounted on the rotating shaft 6 inside the pulverizing chamber 2 through the cutter disc 10 and are distributed in a circular array.

[0044] The cutters are evenly spaced to facilitate chopping of the medicinal materials, which are then cut into suitable sizes and sieved out from the screening assembly at the bottom.

[0045] Please see the attached Figure 5 Specifically, arc-shaped clamping plates 12 are arranged coaxially with the rotating shaft 6 on both sides of the inner wall of the crushing chamber 2. The two arc-shaped clamping plates 12 are installed opposite to each other and arc-shaped grooves along the arc direction of the arc-shaped clamping plates 12 are opened on the opposite surfaces. The arc-shaped grooves extend to the ends of the arc-shaped plates 12.

[0046] Please combine the attached Figure 5 and attached Figure 6 Specifically, the screening component is an arc-shaped screening plate 13, both sides of which are inserted into the arc-shaped grooves of the arc-shaped clamping plate 12 and can be kept sliding in the arc-shaped grooves, and a plurality of screening holes are opened on the arc-shaped surface of the arc-shaped screening plate 13.

[0047] Please refer to the attached Figure 6 Specifically, the arc-shaped clamping plate 12 and the arc-shaped screening plate 13 are both semi-cylindrical in shape.
