[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figures 1-3As shown, a dustproof device for a conveyor belt includes an upper cover 1, a lower cover 2, and a scraper structure. The upper cover 1 and lower cover 2 are hinged together on one side, and a buckle 6 for fastening the upper cover 1 and lower cover 2 is provided on the other side. A handle 5 is fixedly provided on the outer wall of the upper cover 1 for easy gripping and rotation of the upper cover 1. The upper cover 1 and lower cover 2 form a sealed dustproof cover. A conveyor belt body 3 is fitted inside the lower cover 2. The conveyor belt body 3 can be horizontally or inclined. The conveyor belt body 3 includes a drive roller 4 for driving the conveyor belt body 3. A motor 7 for driving the drive roller 4 is fixedly provided on the lower cover 2. The drive roller 4 is rotatably connected to the lower cover 2. A rotating rod 8 is rotatably mounted through one side wall of the lower cover 2, opposite to the other side wall. A rotating support rod 15 is provided, and a cleaning roller 10 is installed between the rotating rod 8 and the support rod 15. A transmission structure is also provided between the transmission roller 4 and the rotating rod 8. A feeding structure is provided at the top of the upper cover 1, and a discharging structure is provided at the bottom of the lower cover 2. A scraper structure is movably fitted inside the lower cover 2 and cooperates with the cleaning roller 10 to periodically clean the material on the cleaning roller 10. The material reaches the conveyor belt body 3 from the feeding structure. The output end of the motor 7 rotates, driving the transmission roller 4 to rotate. Then, the conveyor belt body 3 carries the material to the unloading point. The conveyor belt body 3 continues to drive the material to fall to the discharging structure. The material is in a relatively sealed state during the conveying process, so the material will not fly and spread to the external environment, and it can reduce the amount of external dust falling into the material and affecting the material quality.
[0028] In some specific implementation plans, such as Figure 2 As shown, in order to reduce the amount of material flying out of the feed cylinder 21, the feeding structure includes a feed cylinder 21 and a closing plate 22. The feed cylinder 21 is installed through the top of the upper cover 1. The closing plate 22 is hinged to an inner wall of the conveyor belt body 3. A torsion spring is also provided between the closing plate 22 and the feed cylinder 21. The closing plate 22 is in a closed state when there is no material gravity. When the material falls to the top of the closing plate 22, it will fall to the top of the conveyor belt body 3 due to gravity.
[0029] In some specific implementation plans, such as Figure 2 As shown, in order to facilitate the control of the discharge speed, the discharge structure includes a discharge hopper 16. The discharge hopper 16 is bucket-shaped and is connected through to the bottom of the lower cover 2. A gate 161 is also slidably connected to the bottom of the discharge hopper 16. The discharge hopper 16 is located at the bottom of the conveyor belt body 3 away from the feed cylinder 21. A handle is provided on the side of the gate 161. The user can adjust the discharge quantity by controlling the position of the gate 161.
[0030] In some specific implementation plans, such as Figure 1As shown, in order to facilitate the rotation of the cleaning roller 10 during the rotation of the transmission roller 4, the transmission structure includes a synchronous belt 9. The outer sides of the transmission roller 4 and the rotating rod 8 are provided with corresponding synchronous pulleys. The synchronous belt 9 is fitted on the outer side of the two synchronous pulleys. As the motor 7 rotates, due to the transmission effect of the synchronous belt 9, the rotating rod 8 drives the cleaning roller 10 to rotate in contact with the conveyor belt body 3. During use, some material will adhere to the conveyor belt body 3. The material is scraped into the hopper 16 and discharged under the cleaning action of the rotating cleaning roller 10.
[0031] In some specific implementation plans, such as Figure 3 As shown, to facilitate the replacement of the cleaning roller 10, a relief groove 12 is provided on the side of the rotating rod 8 near the cleaning roller 10, and a slot 11 is provided on the side of the cleaning roller 10 near the rotating rod 8. A threaded rod 14 is threadedly connected to the side of the rotating rod 8 away from the cleaning roller 10, and a cross rod 13 is rotatably connected to the side of the threaded rod 14 near the cleaning roller 10. The cross rod 13 is inserted through the slot 11 and the relief groove 12. A groove corresponding to the abutment rod 15 is provided on the side of the cleaning roller 10 away from the rotating rod 8 to abut against the rod 15. The rod 15 is inserted into the groove, and a force rod 23 is fixedly installed on the rotating rod 8. When the cleaning roller 10 needs to be replaced, hold the force rod 23 with one hand to prevent the rotating rod 8 from rotating, and then use the other hand to rotate the threaded rod 14 to drive the cross rod 13 to move so that the cross rod 13 moves into the relief groove 12. After replacing the cleaning roller 10, rotate the threaded rod 14 in the opposite direction to drive the end of the cross rod 13 into the slot 11 to realize the installation of the cleaning roller 10, which can realize the quick replacement of the cleaning roller 10.
[0032] In some specific implementations, to facilitate the periodic scraping of material off the outer wall of the cleaning roller 10, the scraper structure includes a feed rod 17, which is rotatably connected to the bottom plate of the lower cover 2. A motor 18 for driving the feed rod 17 to rotate is fixedly installed on the lower cover 2. A scraper body 19 is threadedly connected to the outer side of the feed rod 17. A limit rod 20 is fixedly installed on the inner wall of the lower cover 2, which passes through the scraper body 19 and is slidably connected to it. The scraper body 19 cooperates with the cleaning roller 10. When the motor 18 is started, it drives the feed rod 17 to rotate, and the scraper body 19 moves upward, so that the scraper body 19 fits against the outer wall of the cleaning roller 10, scraping off the material on the outer wall of the cleaning roller 10 and causing it to fall into the discharge hopper 16, thus avoiding affecting the cleaning effect of the cleaning roller 10.
[0033] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:
[0034] Material arrives on conveyor belt body 3 through feed cylinder 21. The output end of motor 7 rotates, driving transmission roller 4 to rotate. Conveyor belt body 3 then carries material to the unloading point. Conveyor belt body 3 continues to drive material to fall into discharge hopper 16. Material discharge is controlled by control gate 161. As motor 7 rotates, due to the transmission of synchronous belt 9, rotating rod 8 drives cleaning roller 10 to rotate against conveyor belt body 3. During use, some material will adhere to conveyor belt body 3. The material is scraped into discharge hopper 16 and discharged under the cleaning action of the rotating cleaning roller 10. The material is in a relatively sealed state during the conveying process, and the material will not fly and spread to the external environment. A small amount of material and dust accumulates inside the upper cover 1 and lower cover 2, which can be cleaned periodically by opening buckle 6.
[0035] The foregoing has described several embodiments of this utility model in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
