[0022] Working principle: When it is necessary to screen the tea leaves, first pour the tea leaves into the funnel 2, separate the tea leaves through the partition plate, and drop them on the screening plate 3 and on both sides of the convex plate 31. At this time, the tea leaves are initially separated to prevent the tea leaves from piling up in the middle of the screening plate 3. At this time, the motor 6 is started, and the motor 6 drives the rotating shaft 61 to rotate, and the rotating shaft 61 drives the cam 62 to rotate. When the cam 62 rotates to contact the screening plate 3, the screening plate 3 is squeezed, so that the screening plate 3 slides along the inner wall of the screening box 1 through the insertion rod 41. The No. 1 spring 42 is compressed at this time, and the insertion rod 41 drives the rack 43 to move, and the rack 43 and the No. 1 gear 44 are meshed with each other. , so that the No. 1 gear 44 rotates to drive the take-up wheel 46 to rotate, and the traction line is taken up, so that the traction line slides along the guide wheel 45, and pulls the convex plate 31 to slide, so that the convex plate 31 can scrape the tea leaves flat, and the effect of avoiding tea accumulation is achieved again. At this time, the cam 62 is out of contact with the screening plate 3. At this time, the rebound force of the No. 1 spring 42 makes the screening plate 3 move in the other direction, so that the rack 43 in the other direction moves and meshes with the gear in the other direction. The gear in the other direction drives the take-up wheel 46 to rotate, and pulls the convex plate 31 in the opposite direction through the traction line to scrape the tea leaves flat, so as to achieve the effect of scraping the tea leaves left and right, and at this time the cam 62 contacts the screening plate 3 again , repeat the above movement, and when the screening of the tea leaves on the screening plate 3 is completed, the screening plate 3 is directly disassembled, and after pouring out another part of the tea leaves, the screening plate 3 is reinstalled for splitting again. By setting the auxiliary structure 4 and the funnel 2 with the partition plate, the tea leaves can be scraped flat twice in succession to avoid the accumulation of tea leaves on the screening plate 3, which leads to a decrease in screening efficiency. As the rotation speed of the screening plate 3 increases with the cam 62, the speed of the left and right movement of the screening plate 3 also increases, which makes the screening speed of the tea leaves on the screening plate 3 also increase, thereby improving the practicality of the device. When the screened tea leaves fall onto the guide bucket 11, the left and right moving screening plate 3 drives the The tooth 32 moves and meshes with the No. 2 gear 51, and the No. 2 gear 51 rotates a short distance to the left and right, and at the same time, the rotation drives the traction rods 52 on the left and right sides to move. At this time, the traction rod 52 drives the slide bar 54 and the connecting rod 53 to move, and the connecting rod 53 drives the cleaning block 55 to move along the outlet edge of the guide bucket 11. At this time, the slide bar 54 can be retracted to the inside of the traction rod 52, and the No. 2 spring 541 is compressed, so that the cleaning block 55 fits the inner wall of the guide bucket 11, and sweeps the tea leaves remaining at the outlet edge of the guide bucket 11 into the collection box 12, thereby avoiding the accumulation of tea leaves at the outlet of the guide bucket 11 and affecting the discharge rate of the screened tea leaves.
