A drive motor 7 is mounted on the lower side of one side of the mounting frame 4, and the output end of the drive motor 7 passes through one side of the mounting frame 4 and is connected to a rotating rod 8. A driving circular gear 6 is mounted on the outer side of the rotating rod 8. An mounting rod 9 is mounted on the upper side of one side of the mounting frame 4 via a bearing, and a driven circular gear 10 is mounted on the outer side of the mounting rod 9. One end of the mounting rod 9 is bolted to a mounting plate 11, and a screening cylinder 2 is mounted on one side of the mounting plate 11. Both ends of the screening cylinder 2 are provided with sealing grooves 12, and multiple fine screening holes 1 are provided on the outer side of one end of the screening cylinder 2. 5. Multiple intermediate screening holes 14 are provided on the outer side of the middle position of the screening cylinder 2, and multiple coarse screening holes 13 are provided on the outer side of the other end of the screening cylinder 2. A movable frame 17 is provided inside the screening cylinder 2, and a base plate 18 is installed at the bottom end of the movable frame 17. Screws 21 are installed on both sides of the top of the movable frame 17, and a sleeve block 20 is sleeved on the outer side of the screw 21. A cover plate 16 is provided at the top of the movable frame 17. A servo motor 5 is installed at the bottom end of one side of the mounting plate 11, and a threaded rod 3 is connected to the output end of the servo motor 5. A threaded block 1 is sleeved on the outer side of the threaded rod 3, and a connecting block 19 is welded to the top of the threaded block 1. The movable frame 17 is H-shaped, and the two ends of the movable frame 17 are disc-shaped. The diameter of the two ends of the movable frame 17 is the same as the internal diameter of the screening cylinder 2. Both the base plate 18 and the cover plate 16 are disposed inside the sealing groove 12, and the thickness of the base plate 18, the cover plate 16 and the sealing groove 12 is the same. The connecting block 19 and the base plate 18 are located in the same vertical plane, and the top of the connecting block 19 passes through the bottom of the screening cylinder 2 and is connected to the base plate 18. The top end of the lead screw 21 passes through the bottom end of the cover plate 16 and extends above the cover plate 16, and the bottom end of the sleeve block 20 contacts the top end of the cover plate 16. The inner wall of the sleeve block 20 is provided with an internal thread that matches the outer side of the lead screw 21. Driven circular gear 10 and driving circular gear 6 are located in the same vertical plane and are meshed with each other; The centers of the mounting rod 9 and the screening cylinder 2 are located on the same horizontal straight line, and the internal length of the screening cylinder 2 is slightly larger than the length of the threaded rod 3. Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in the operation of this device, firstly, the device has a cover plate 16 and a movable frame 17. Since the outer sides of both ends of the movable frame 17 are in contact with the inner wall of the screening cylinder 2, combined with the contact relationship between the bottom plate 18, the cover plate 16, and the inner wall of the sealing groove 12, the screening cylinder 2, the movable frame 17, the cover plate 16, and the bottom plate 18 can form a relatively closed space. Therefore, this device can utilize the threaded connection between the lead screw 21 and the sleeve block 20 to release the restriction effect on the cover plate 16 by rotating the sleeve block 20. Thus, the cover plate 16 is removed, and the biodegradable material to be graded and screened is poured into the interior of the movable frame 17 through the cover plate 16. Then, the device uses the drive motor 7 to drive the active circular gear 6 to rotate. Due to the meshing relationship between the active circular gear 6 and the driven circular gear 10, the rotation of the active circular gear 6 drives the driven circular gear 10 to rotate, thereby causing the mounting rod 9 to drive the mounting plate 11 to rotate. During the rotation of the mounting plate 11, The biodegradable granular material inside the drive motor 7 can be rolled, allowing it to be graded and screened through the fine screening holes 15, thus achieving the screening effect of this device. To further improve the grading and screening quality and efficiency, the device is equipped with a connecting block 19. The threaded rod 3 can be rotated by the drive of the servo motor 5. The rotation of the threaded rod 3 and the connection of the connecting block 19 restrict the horizontal movement of the threaded block 1. During the horizontal movement of the threaded block 1, the base plate 18 can be moved horizontally through the connection of the connecting block 19, thereby driving the entire movable frame 17 to move horizontally. Since the outer side of the screening cylinder 2 has coarse screening holes 13, medium screening holes 14, and fine screening holes 15, the device can achieve screening of different specifications by moving the movable frame 17 sequentially to the positions of the fine screening holes 15, medium screening holes 14, and coarse screening holes 13. This enables continuous grading and screening, improving the screening efficiency and quality of the device.
