When the motor 17 is working normally, the rotating first rotating rod 18 will drive the two groups of first top members 19 to rotate, and when the first top member 19 is close to the position of the second top member 111, the frame 14 will be lifted up as a whole, and the middle part of the elastic member 13 will be stretched, so that It has elastic force, and when the first top piece 19 and the second top piece 111 are separated, the frame 14 can fall and reset under the action of the elastic piece 13, and the frame 14 is attached with vibration force, and at the same time, the random materials are shaken through the screen 15, and the large pieces of materials are accumulated on the top of the screen 15. This step cooperates with the frame 14 that can be shaken to separate and store the materials accumulated inside it, reducing the large pieces of granular materials mixed with the powdered materials inside, so that the materials need to be stored separately again later, thereby improving the accuracy of collecting the two.
[0027] like Figure 3 and 4As shown, the support plate 12 is fixedly connected to a vertical plate 2 at the bottom; a reciprocating screw 21 is rotatably connected to the middle of the vertical plate 2; a slider 22 is threadedly connected to the middle of the reciprocating screw 21, and the slider 22 is slidably arranged on the inner wall of the vertical plate 2; a connecting rod 23 is fixedly connected to the middle of the slider 22; a scraper 24 is fixedly connected to the end of the connecting rod 23, and the scraper 24 is in contact with the middle of the first rotating rod 18; a belt 25 is rotatably connected to the end of the reciprocating screw 21, and the other end of the belt 25 is rotatably connected to the middle of the first rotating rod 18; when working, the vertical plate 2 is arranged at the bottom of the support plate 12, so that when the first rotating rod 18 rotates, the belt 25 is rotated.

This step cooperates with the bent guide plate 5 to guide the material. At the same time, when the material is being screened, the inner wall of the guide plate 5 can block part of the material to reduce the problem of its transfer to the outside.
[0031] like Figure 3 As shown, a soft strip 6 is fixedly connected to the middle part of the knocking piece 41, and the soft strip 6 is arranged at the top of the frame 14; when working, by arranging the soft strip 6 in the middle part of the knocking piece 41, the knocking piece 41 can bend and deform the middle part of the soft strip 6 under the action of inertia when working, and its end will contact the top of the frame 14. This step cooperates with the arrangement of the soft strip 6 to increase the area of the material on the top of the frame 14, and further improve the speed of screening the material on the screen 15.
[0032] like Figure 4-5 As shown, an observation port 7 is fixedly connected to the middle of the sliding frame 31; when working, by setting the observation port 7 in the middle of the sliding frame 31, the staff can observe the working status of the frame 14 through the observation port 7.

By providing a support plate 12 at the bottom of the discharge port 11, when the powdered material is discharged, the material will first contact the top of the frame 14, and at the same time, under the action of the middle inclined surface, the material can be close to the position of the screen 15. When the motor 17 is working normally, the rotating first rotating rod 18 will drive the two sets of first top pieces 19 to rotate, and when the first top piece 19 is close to the position of the second top piece 111, it will The frame 14 is lifted upward as a whole, and the middle part of the elastic member 13 is stretched to make it have elastic force. When the first top member 19 is separated from the second top member 111, the frame 14 can fall and reset under the action of the elastic member 13, and the frame 14 is attached with vibration force. At the same time, the random materials are shaken through the screen 15, and large pieces of materials are accumulated on the top of the screen 15. By arranging a vertical plate 2 at the bottom of the support plate 12, the first rotating rod 18 can drive the reciprocating screw 21 to rotate in the middle part of the vertical plate 2 under the action of the belt 25 when rotating. At the same time, the belt 25 will reciprocate in the middle of the reciprocating screw 21, so that the connecting rod 23 and the scraper 24 will follow The slider 22 moves synchronously, and the impurities attached to the middle of the first rotating rod 18 are cleaned and scraped off. By setting two sets of slide grooves 3 in the middle of the grinder body 1, when the grinder body 1 is working as a whole, the staff can align the specified position of the sliding frame 31 with the slide groove 3 and press it down, and at the same time wrap the support plate 12 as a whole inside the sliding frame 31. When the sliding frame 31 is pulled up and removed, under the action of inertia, the impact ball 33 will hit the inner wall of the sliding frame 31 and vibrate and clean the impurities attached to the inner wall. By setting a rotating second rotating rod 4 in the middle of the second connecting plate 110, the second connecting plate 110 can move upward or downward. During movement, the stationary knocking piece 41 will first separate from the top of the frame 14, and then use the gravity of the knocking piece 41 to vibrate the top of the frame 14. By providing a bent guide plate 5 in the middle of the support plate 12, the material discharged from the end of the discharge port 11 will contact the top of the guide plate 5 first, and then be transferred to the middle position of the screen 15.
