[0015] Compared with the prior art, the beneficial effects of this utility model are: the tobacco leaf sorting equipment not only makes it easy to screen broken leaves and adjust the position of the lighting lamp, but also makes it easy to pick up broken leaves;

[0016] (1) By setting up a fixed plate, a movable block, a screen plate, a drive motor and a damper, the drive mechanism drives the conveyor roller to rotate and convey tobacco leaves. Workers can select tobacco leaves. Broken leaves and impurities will fall into the processing box through the gap between the conveyor rollers. Start the drive motor, and the drive motor drives the movable block to rotate through the rotating shaft. This allows the movable block to squeeze the movable plate and the return spring to drive the screen plate to sway left and right to screen the debris. Dust and impurities fall into the storage box. Larger broken leaves are at the top of the screen plate. Screening broken leaves can make use of them and reduce waste.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 The present invention provides an embodiment of a tobacco leaf sorting device, comprising a frame 1, with four corner supports 17 fixedly connected to the bottom of the frame 1, a conveying roller 2 movably installed inside the frame 1, and processing boxes 7 fixedly connected to the left and right sides of the bottom of the frame 1, with a screening mechanism provided between the processing boxes 7.

[0026] The screening mechanism includes a fixed plate 14, a movable block 15, and a screen plate 16. The fixed plate 14 is fixedly connected to the middle position of the rear end of the frame 1. A drive motor 18 is installed at the rear end of the fixed plate 14. A rotating shaft 19 is fixedly connected to the output end of the drive motor 18. The movable block 15 is fixedly connected to the front end of the rotating shaft 19. The screen plate 16 is movably connected through the bottom end of the inside of the processing box 7. A movable plate 20 is fixedly connected to the side of the screen plate 16 near the middle. A return spring 21 is installed between the movable plate 20 and the processing box 7. A damper 22 is provided inside the return spring 21.

[0027] The mesh plate 16 slides left and right at the bottom inside the processing box 7. The movable block 15 is set between the movable plates 20. The bottom of the processing box 7 is provided with a storage box 13. The rear end of the frame 1 is provided with a drive structure, which is connected to the conveyor roller 2.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the drive mechanism drives the conveyor roller 2 to rotate and convey tobacco leaves. Workers can select tobacco leaves. Broken leaves and impurities will fall into the processing box 7 through the gaps between the conveyor rollers 2. The drive motor 18 is started, and the drive motor 18 drives the movable block 15 to rotate through the rotating shaft 19. This causes the movable block 15 to squeeze the movable plate 20 and the return spring 21, causing the screen plate 16 to shake left and right to screen the debris. Dust and impurities fall into the storage box 13. Larger broken leaves are at the top of the screen plate 16. Screening broken leaves can make use of them and reduce waste.

[0029] Support rods 3 are fixedly connected to the front and rear ends of the top of frame 1. A mounting plate 4 is set at the top of the support rod 3. A lighting lamp 5 is installed on the right side of the bottom end of the mounting plate 4. A mounting rod 6 is fixedly connected to the left side of the bottom end of the mounting plate 4. A support block 24 is fixedly connected to the top of the inside of the support rod 3. A limit rod 23 is fixedly connected to the top of the support block 24. Multiple sets of lighting lamps 5 are provided. The mounting rod 6 is set at the top of the inside of the support rod 3. The limit rod 23 is embedded in the inside of the mounting rod 6. The mounting rod 6 rotates outside the limit rod 23.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, the lighting lamp 5 can illuminate the top and front and rear ends of the frame 1, making it convenient for workers to select tobacco leaves. When the position of the lighting lamp 5 needs to be adjusted, the mounting plate 4 is rotated. The mounting plate 4 drives the mounting rod 6 to rotate outside the limit rod 23, which is highly flexible and can control the position of the lighting lamp 5 according to the needs of the workers.

[0031] The front end of the processing box 7 is provided with a reserved slot 10. The top of the reserved slot 10 is fixedly connected to a hinge shaft 9. The outside of the hinge shaft 9 is movably hinged to a baffle 8. The left and right sides of the front end of the processing box 7 are movably hinged to limit blocks 11. The front end of the baffle 8 is fixedly connected to a pull block 12. The hinge shaft 9 is located at the top of the inside of the baffle 8. The limit blocks 11 are located on the left and right sides of the front end of the baffle 8.

[0032] Specifically, such as Figure 1 As shown, when it is necessary to remove the broken leaves at the top of the mesh plate 16, rotate the limiting block 11 to make the baffle 8 unfixed, and then pull the pull block 12. The pull block 12 drives the bottom end of the baffle 8 to move and open the baffle 8. Opening the baffle 8 makes it convenient for the staff to remove the broken leaves at the top of the mesh plate 16 through the reserved slot 10. After removing them, rotate the limiting block 11 to the front end of the baffle 8 to limit and fix the baffle 8.

[0033] Working principle: In use, the drive mechanism of this invention rotates the conveyor rollers 2 to transport tobacco leaves, allowing workers to select them. The lighting 5 illuminates the top and front and rear ends of the frame 1, facilitating leaf selection. To adjust the position of the lighting 5, the mounting plate 4 rotates, causing the mounting rod 6 to rotate outside the limit rod 23. This provides high flexibility, allowing the position of the lighting 5 to be controlled according to worker needs. Broken leaves and impurities fall through the gaps between the conveyor rollers 2 into the processing box 7. The drive motor 18 is activated, and through the rotating shaft 19, it drives the movable block 15 to rotate, thus... The movable block 15 presses against the movable plate 20 and the return spring 21, causing the mesh plate 16 to sway left and right to screen the debris. Dust and impurities fall into the storage box 13. Larger debris is at the top of the mesh plate 16. Screening the debris allows for its utilization and reduces waste. When it is necessary to remove the debris at the top of the mesh plate 16, the limiting block 11 is rotated to loosen the baffle 8. Then, the pull block 12 is pulled, which moves the bottom of the baffle 8 to open it. Opening the baffle 8 makes it easier for staff to remove the debris at the top of the mesh plate 16 through the reserved slot 10. After removal, the limiting block 11 is rotated to the front of the baffle 8 to limit and fix the baffle 8.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
