Technical Field
[0001] This utility model relates to the field of feeding machines, and more specifically, to a dustproof feeding machine for rare earth processing. Background Technology
[0002] Bucket elevators are continuous conveying machines that vertically lift materials using a series of buckets uniformly fixed to an endless traction component. They are widely used in industries such as metallurgy, chemicals, building materials, and food processing for the vertical lifting and conveying of powdery, granular, and small lump materials. In the rare earth processing field, bucket elevators also play an important role, often used to lift raw materials such as rare earth powder and rare earth oxides from a low position to a higher inlet for subsequent processes such as crushing, grinding, and reaction tanks.
[0003] However, existing bucket elevators suffer from significant dust pollution during the feeding and conveying process. The buckets of bucket elevators are mostly open structures. When transporting powdery or granular materials, the vibration of the buckets during lifting and the airflow within the plant cause fine particles to easily escape from the bucket openings. This not only pollutes the workshop environment and affects worker health but also results in material waste. For rare earth materials, due to their typically high value and the fact that some materials possess toxicity or radioactivity, the environmental and health risks posed by dust pollution are particularly prominent. To address these issues, one solution involves installing bucket covers on top of the buckets to create a sealed cavity during conveying, preventing material from falling out due to vibration and airflow. However, this requires electronic control equipment to open the bucket covers during feeding in the feeding area, increasing costs. Therefore, we propose a dustproof feeding machine for rare earth processing. Utility Model Content
[0004] The purpose of this invention is to solve the problem that the opening and closing of the lid using electronic equipment is currently costly.
[0005] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a dustproof feeding machine for rare earth processing, comprising two side baffles, two sets of transmission wheels between the two side baffles, a transmission belt sleeved on the two sets of transmission wheels, a hopper mounted on the transmission belt, two sets of connecting ears fixedly connected to the right side surface of the hopper, a cover plate on the hopper, the cover plate being rotatably connected to the connecting ears, an extension plate fixedly connected to the right side surface of the cover plate, a lever fixedly connected to the lower side surface of the extension plate, a spring fixedly connected between the lower side surface of the extension plate and the right side surface of the hopper, and a triggering and adjusting assembly on the side baffles.
[0006] As a preferred technical solution of this application, the triggering and adjustment component includes two guide rails, which are fixedly connected to the adjacent side surfaces of the two side baffles. Each of the two guide rails is provided with a sliding seat, and each of the adjacent side surfaces of the two sliding seats is fixedly connected with a sleeve.

[0009] As a preferred technical solution of this application, both threaded rods extend into the interior of the sleeve, the two threaded rods are mirror images of each other, and a limiting groove is formed on the inner wall of the sleeve.
[0010] As a preferred technical solution of this application, the outer surface of the threaded rod is threaded with a locking sleeve, and the locking sleeve is slidably connected to the sleeve through a limiting groove.
[0011] As a preferred technical solution of this application, the sliding seat is provided with a hole that communicates with the inner diameter of the sleeve.
[0012] As a preferred technical solution of this application, an arc-shaped baffle is fixedly connected between the two side baffles, and the arc-shaped baffle is coaxially arranged with the transmission wheel at the higher position.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1.

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0019] Example 1 Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A dustproof feeding machine for rare earth processing includes two side baffles 1, with two sets of transmission wheels 2 for power transmission between the two side baffles 1. A transmission belt 3 is driven onto the two sets of transmission wheels 2, and a hopper 4 is installed on the transmission belt 3. Two sets of connecting ears 5 for component connection are fixedly connected to the right side surface of the hopper 4. A cover plate 6 for closing the hopper 4 is provided on the hopper 4. The cover plate 6 is rotatably connected to the connecting ears 5. An extension plate 7 is fixedly connected to the right side surface of the cover plate 6. A lever 8 is fixedly connected to the lower side surface of the extension plate 7. A spring 9 for auxiliary reset is fixedly connected between the lower side surface of the extension plate 7 and the right side surface of the hopper 4. A triggering and adjusting assembly is provided on the side baffles 1.
[0020] The transmission wheel 2 is driven to rotate by an external drive device, which in turn drives the hopper 4 to lift rare earth by the conveyor belt 3. The trigger and adjustment components work with the lever 8. When the hopper 4 moves to the feeding area, the lever 8 is blocked and cannot move with the hopper 4. Therefore, when the hopper 4 continues to move, the lever 8 can drive the cover plate 6 to open. When the cover plate 6 is opened, the extension plate 7 can compress the spring 9 to prepare for subsequent reset.
[0021] Example 2 The dustproof feeder for rare earth processing provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the triggering and adjustment assembly includes two guide rails 10 that serve as trajectory guides. The two guide rails 10 are fixedly connected to the adjacent surfaces of the two side baffles 1. Each guide rail 10 is provided with a sliding seat 11. A sleeve 12 is fixedly connected to the adjacent surfaces of the two sliding seats 11. A gap is provided between the two sleeves 12. A rotating cylinder 13 is rotatably fitted onto the outer surface of the two sleeves 12. A fixing block 14 is fixedly connected to the inner wall of the rotating cylinder 13. Two threads for driving are fixedly connected to the fixing block 14. The two threaded rods 15 extend into the interior of the sleeve 12. The two threaded rods 15 are mirror images of each other. The inner wall of the sleeve 12 has a limiting groove 16. The outer surface of the threaded rod 15 is threaded with a locking cylinder 17 that plays a locking role. The locking cylinder 17 is slidably connected to the sleeve 12 through the limiting groove 16. The sliding seat 11 has a hole 18 that communicates with the inner diameter of the sleeve 12. An arc-shaped baffle 19 is fixedly connected between the two side baffles 1. The arc-shaped baffle 19 is coaxially set with the transmission wheel 2 at the top.
[0022] When the lever 8 contacts the rotating drum 13, it is blocked. The hopper 4 continues to move, and the cover plate 6 can be opened with the help of the lever 8 and the extension plate 7. When the lever 8 moves past the rotating drum 13, the cover plate 6 can be reset by the spring 9. At the same time, when it is necessary to fine adjust the opening position of the rotating drum 13 and the cover plate 6, the rotating drum 13 can be rotated, which will drive the fixed block 14 and the two threaded rods 15 to rotate. Since the locking cylinder 17 is slidably connected to the sleeve 12 through the limiting groove 16, and the locking cylinder 17 is threaded Sleeves are fitted on the outer surface of the threaded rod 15, so when the threaded rod 15 rotates, it can drive the locking cylinder 17 to move horizontally. At this time, the locking cylinder 17 can be controlled to pass through the hole 18 and contact or separate from the guide rail 10. After separation, the sliding seat 11 can be pushed to move for adjustment. After adjustment, the locking cylinder 17 can be locked when it contacts the guide rail 10. At the same time, when the hopper 4 moves to the highest position, its lever 8 contacts the arc-shaped baffle 19 and opens the cover plate 6 again, so that the cover plate 6 is automatically opened when the hopper 4 flips to discharge material.
[0023] The usage process of the dustproof feeding machine for rare earth processing provided by this utility model is as follows: When the hopper 4 moves to the low-level feeding area under the drive of the conveyor belt 3, the lever 8 first contacts the rotating drum 13. Since the rotating drum 13 is fixed to the side baffle 1 by the sleeve 12 and the sliding seat 11, the lever 8 is blocked by the rotating drum 13 and cannot continue to move upward with the hopper 4. However, the hopper 4 continues to move under the drive of the conveyor belt 3. Therefore, after the lever 8 is blocked, it drives the cover plate 6 to rotate around the connecting ear 5 through the extension plate 7, so that the cover plate 6 gradually opens and the upper opening of the hopper 4 is exposed. At this time, the external feeding equipment can load rare earth materials into the hopper 4. During the opening of the cover plate 6, the extension plate 7 compresses the spring 9 downward, so that the spring 9 stores elastic potential energy. When the lever 8 continues to move with the hopper 4 to the position of passing the rotating drum 13, the lever 8 disengages from the rotating drum 13, the spring 9 releases elastic potential energy, pushes the extension plate 7 to reset, and then drives the cover plate 6 to re-close the upper opening of the hopper 4, so as to achieve the sealing and dust prevention of the hopper 4 during the lifting and transportation process.
[0024] At the same time, when the hopper 4 moves to the highest point (i.e., the position after passing the upper transmission wheel 2), the lever 8 contacts the arc-shaped baffle 19 fixedly connected between the two side baffles 1. The arc-shaped baffle 19 and the transmission wheel 2 at the higher position are coaxially set. The lever 8 is blocked by the arc-shaped baffle 19. Similarly, the extension plate 7 drives the cover plate 6 to open, so that the cover plate 6 automatically opens when the hopper 4 is flipped to unload, and the material is smoothly discharged from the hopper 4 to the subsequent work station.
[0025] When it is necessary to adjust the opening position of the cover plate 6 according to the actual working conditions (i.e., the triggering time when the adjusting lever 8 is blocked), the operator can rotate the rotating drum 13. The rotating drum 13 drives the fixed block 14 and the two threaded rods 15 to rotate synchronously. Since the locking cylinder 17 is slidably connected to the sleeve 12 through the limiting groove 16 and cannot rotate, and the locking cylinder 17 is threaded onto the outer surface of the threaded rod 15, the rotation of the threaded rod 15 drives the locking cylinder 17 to move horizontally along the axial direction of the sleeve 12. When the locking cylinder 17 retracts inward and separates from the guide rail 10, the sliding seat 11 can slide freely along the guide rail 10. The operator can adjust the position of the rotating drum 13 by pushing the sliding seat 11. After the adjustment is completed, the rotating drum 13 is rotated in the opposite direction, so that the locking cylinder 17 moves outward and passes through the hole 18 to abut against the guide rail 10. The friction between the locking cylinder 17 and the guide rail 10 locks the sliding seat 11 in the adjusted position, thereby achieving precise adjustment of the opening trigger position of the cover plate 6.
[0026] Each hopper 4 sequentially completes the above-mentioned cycle of "low-position opening for receiving material - closed lifting - high-position opening for unloading - closed return", thus achieving continuous dust-proof feeding operations.
