During operation, by setting the upper fixed block 26 at the bottom end of the screening box 1, the filter plate 6 can be supported at one point. In addition, an inclined chute 27 is provided on the fixed block 26, so that the dry powder that does not meet the use standard slides down from the filter plate 6, falls into the inclined chute 27, and then slides into the second through groove 7. From the second through groove 7, it slides into the screening box 1, and the staff can prepare things in advance and then put it into the crushing box 29 for secondary crushing. When all the dry powder is crushed and falls into the storage box 28, the staff can pull the storage box 28 out of the screening box 1 through the second through groove 7.

[0031] A group of connecting blocks 30 are fixedly connected to the bottom end of the screening plate 2; a group of the connecting blocks 30 are hinged with a second connecting rod 31 at the bottom end; a group of the connecting blocks 30 and the second connecting rod 31 are hinged with a torsion spring at the hinge; a group of the second connecting rods 31 are fixedly connected with elastic balls 32 at the bottom end.

When the power member drives the screening plate 2 to move, the second connecting rod 31 and the elastic ball 32 will form an extrusion with the filter plate 6, so that the second connecting rod 31 is tilted, and then the second connecting rod 31 is hinged with the connecting block 30 due to the torsion spring. When the screening plate 2 moves back, the torsion spring rebounds and drives the second connecting rod 31 to rebound, so that the screening plate 2 shakes, and when the elastic ball 32 on one side touches the filter plate, the other side does not touch it.

[0032] Working principle: after the staff places the dry powder on the crushing piece and crushes it, the dry powder falls from the crushing piece into the screening box 1, and then a screening plate 2 is set inside the screening box 1. After the dry powder smoothly falls onto the screening plate 2, it is driven by the power piece to make the support plates 4 on both sides of the screening plate 2 slide, and the crushed dry powder is screened in the form of shaking back and forth. Because the screening holes 5 are relatively large, the dry powder that meets the standards can be dropped from the screening plate 2 to the filter plate 6 first. The holes on the filter plate 6 are small, and only the dry powder that meets the standards can be dropped. Then, the larger dry powder that falls from the screening plate 2 and does not meet the use standards will slide from the filter plate 6 to both sides, so that the dry powder that does not meet the use standards and the dry powder that meets the use standards are separated. An upper chassis 8 is arranged on one side of the screening box 1 in order to drive the screening plate 2 to screen the dry powder. A second through slot 7 is provided on one side of the chassis 8 so that the chassis 8 and the screening box 1 can be communicated.

When the turntable 13 rotates, the first rotating shaft can pull the first connecting rod 15, so that the first connecting rod 15 pulls the connecting column 16 to make the screening plate 2 shake and screen the dry powder. An upper crushing piece is arranged on the top of the screening box 1 in order to crush the powder before screening. In order to make the larger dry powder blocks become powder after crushing and meet the use standards, after the staff puts the dry powder blocks from the feed port 19 into the crushing box 29, the linkage drives the second rotating rod 20, and the second rotating rod 20 rotates to rotate the crushing roller 21 to crush the dry powder blocks. The first sprocket 22 is fixed to the outer circular wall of the first rotating rod 12, and the second sprocket 23 is set on the outer circular wall of the second rotating rod 20, and then the chain 24 is used to drive the second rotating rod 20 to rotate. The upper gear 25 is set on the second rotating rod 20 to make the second rotating rod 20 rotate in opposite directions, so that the crushing roller 21 can be driven to crush the dry powder in opposite directions. An upper fixed block 26 is provided at the bottom to support the filter plate 6. An inclined chute 27 is provided on the fixed block 26 to allow the dry powder that does not meet the use standard to slide down from the filter plate 6, fall into the inclined chute 27, and then slide into the second through slot 7. From the second through slot 7, it slides into the screening box 1. The staff can prepare things in advance and then put them into the crushing box 29 for secondary crushing. When all the dry powder is crushed and falls into the storage box 28, the staff can pull the storage box 28 out of the screening box 1 through the second through slot 7, and fix the upper connecting block 30 at the bottom end of the screening plate 2. The second connecting rod 31 is hinged at the bottom end of the connecting block 30 through a torsion spring. When the power component drives the screening plate 2 to move,The second connecting rod 31 and the elastic ball 32 will form an extrusion with the filter plate 6, causing the second connecting rod 31 to tilt. Then, the second connecting rod 31 and the connecting block 30 are hinged with a torsion spring. When the screening plate 2 moves back, the torsion spring rebounds and drives the second connecting rod 31 to rebound, causing the screening plate 2 to shake. When the elastic ball 32 on one side touches the filter plate, the other side does not touch it.
