A sieve plate 12 is inserted between a group of fixed plates 6, and the sieve plate 12 is fixedly connected to the limiting slider 10.

By rotating the locking nut 11, the locking nut 11 is separated from the locking screw 9, and then the sieve plate 12 can be pulled outward. At this time, the limiting slider 10 is pulled out from the inside of the limiting slide groove 8, and the sieve plate 12 can be taken out from the inside of the box body 1, so as to facilitate better removal of the screened drugs on the sieve plate 12.

As shown in reference figure 1, a driving shaft 13 is rotatably connected to the upper part of the interior of the box body 1, a stirring blade 14 is fixedly connected to the driving shaft 13 inside the box body 1, a driving motor 15 is fixedly connected to the right wall of the box body 1, and the output end of the driving motor 15 is fixedly connected to the driving shaft 13.
