The bottom of the screening chamber 2 is connected to the top of the collecting chamber 3. The hydraulic rod 24 can push the filter frame 23 to move left and right. The positioning rod 21 on the left side of the filter frame 23 will move left and right repeatedly inside the fixed cylinder 22 driven by the filter frame 23. The front end of the bottom of the filter frame 23 is a placement plate, and the bottom of the upper half of the filter frame 23 is a filter screen 231. The front side of the filter screen 231 is connected to the rear side of the placement plate. The filter frame 23 is low in front and high in the back, forming a small acute angle with the horizontal plane. The gypsum mortar rolled inside the rolling chamber 1 will fall on the upper end of the filter screen 231 of the filter frame 23. During the repeated left and right movement of the filter frame 23, the gypsum mortar The mortar is continuously screened by the filter screen 231, and the gypsum particles of suitable size will fall down through the filter holes of the filter screen 231. Because the filter frame 23 has an inclined angle, the unqualified gypsum particles will continue to move forward during the repeated left and right movements of the filter frame 23, and finally fall onto the placement plate, where they accelerate forward and fall into the discharge hopper 5. A collection frame 4 is placed in the placement cavity inside the collecting chamber 3. The gypsum mortar filtered by the filter screen 231 will fall into the collection frame 4 of the collecting chamber 3, and the collection frame 4 can be taken out.
