Dustproof protective structure for vibrating screen

Abstract

This utility model provides a dustproof protection structure for a vibrating screen, including a feed pipe. Two rotating shafts are rotatably connected to the feed pipe via bearings. Dustproof plates are fixedly installed on both rotating shafts. Movable plates are fixedly installed at both ends of the two rotating shafts extending to the outer end of the feed pipe. Movable grooves are opened inside the four movable plates. When the material falls, it contacts the two dustproof plates and applies pressure. The connecting plate compresses the spring, allowing the spring to store elastic potential energy. After the material continues to pass through, the spring pushes the connecting plate to reset. Then, through the rotating plate, connecting shaft, and movable plates, the dustproof plates rotate around the rotating shafts to close, which can immediately block the feed pipe and prevent the dust generated during the vibrating screen from spreading outward from the feed pipe, achieving a highly efficient dustproof effect and ensuring a clean working environment and the health of operators.

Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically to a dustproof protection structure for vibrating screens. Background Technology

[0002] A vibrating screen is a mechanical device that uses vibration to classify, screen, and remove impurities from solid materials. It is widely used in industries such as mining, building materials, chemicals, and food. The operation of a vibrating screen naturally generates dust; therefore, dust prevention is crucial for ensuring equipment operation, environmental safety, and personnel health.

[0003] The existing vibrating screens have no protective design for the feed inlet. After the material passes through, the feed pipe opening cannot be sealed in time. During the vibrating screen process, the dust generated by the impact of the material and the vibration of the screen will spread out of the feed inlet in large quantities, which not only pollutes the working environment, but also poses a threat to the health of the operators. Utility Model Content

[0004] This utility model addresses the technical problem of a dustproof protection structure for vibrating screens, which is provided to solve the problem that the feed inlet lacks a protective design, and the opening cannot be sealed immediately after the material passes through, resulting in a large amount of dust generated by the vibrating screen spreading, polluting the working environment and threatening the health of the operators.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a dustproof protection structure for a vibrating screen, including a feed pipe. Two rotating shafts are rotatably connected to the feed pipe via bearings. Dustproof plates are fixedly installed on both rotating shafts. Movable plates are fixedly installed at both ends of the two rotating shafts extending to the outer end of the feed pipe. Movable grooves are opened inside the four movable plates. Two sliding grooves are opened on the inner wall of each of the four movable grooves. Connecting shafts are provided inside the four movable grooves. Both ends of the four connecting shafts are slidably and rotatably connected to the sliding grooves.

[0007] In this technical solution, a rotating plate is fixedly installed on each of the four connecting shafts.

[0008] In this technical solution, a connecting plate is fixedly installed at the bottom end of each of the multiple rotating plates.

[0009] In this technical solution, four fixing plates are fixedly installed on the feed pipe, and each of the four fixing plates has a through hole.

[0010] In this technical solution, a connecting rod is fixedly installed at the bottom end of each of the multiple connecting plates, and the multiple connecting rods pass through the fixed plate through through holes.

[0011] In this technical solution, all of the connecting rods are slidably connected to the fixed plate.

[0012] In this technical solution, springs are sleeved on the outer surfaces of multiple connecting rods, and the two ends of the multiple springs abut against the fixing plate and the connecting plate, respectively.

[0013] In this technical solution, threaded grooves are provided inside all four connecting rods.

[0014] In this technical solution, each of the four threaded grooves is internally threaded with a threaded post.

[0015] In this technical solution, limit plates are fixedly installed on all four threaded posts.

[0016] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0017] The positive and progressive effects of this utility model are as follows:

[0018] The dustproof protection structure for the vibrating screen mentioned above works by applying pressure to the two dustproof plates during the material's descent. The connecting plate compresses the spring, allowing the spring to store elastic potential energy. After the material continues to pass through, the spring pushes the connecting plate to reset. Then, through the rotating plate, connecting shaft, and movable plate, the dustproof plates are driven to rotate around the rotating shaft and close. This can immediately block the feed pipe, preventing dust generated during the vibrating screen from spreading outward from the feed pipe. This provides a highly efficient dustproof function, ensuring a clean working environment and the health of the operators.

[0019] By rotating the limiting plate until the threaded post on the limiting plate disengages from the connecting rod, the limiting plate and the connecting rod are separated. After the limiting is released, the connecting rod is pushed upward through the through hole of the fixing plate, and the old spring can be removed for replacement. There is no need to disassemble the overall structure, which simplifies the spring replacement process, reduces maintenance difficulty and time consumption, and extends the overall service life of the device.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1-5 As shown, the dustproof protection structure for the vibrating screen includes a feed pipe 1. Two rotating shafts 5 are rotatably connected to the feed pipe 1 via bearings. Dustproof plates 15 are fixedly installed on both rotating shafts 5. Movable plates 12 are fixedly installed at both ends of the two rotating shafts 5 extending to the outer ends of the feed pipe 1. Movable grooves 6 are opened inside the four movable plates 12. Two sliding grooves 11 are opened on the inner walls of the four movable grooves 6. Connecting shafts 7 are provided inside the four movable grooves 6. Both ends of the four connecting shafts 7 are slidably and rotatably connected to the sliding grooves 11.

[0034] In this technical solution, a rotating plate 10 is fixedly installed on each of the four connecting shafts 7.

[0035] In this technical solution, a connecting plate 9 is fixedly installed at the bottom end of each of the multiple rotating plates 10.

[0036] In this technical solution, four fixing plates 2 are fixedly installed on the feed pipe 1, and each of the four fixing plates 2 has a through hole.

[0037] In this technical solution, a connecting rod 3 is fixedly installed at the bottom of each of the multiple connecting plates 9, and the multiple connecting rods 3 pass through the fixing plate 2 through through holes.

[0038] In this technical solution, all of the connecting rods 3 are slidably connected to the fixed plate 2.

[0039] In this technical solution, springs 8 are sleeved on the outer surfaces of multiple connecting rods 3, and the two ends of the multiple springs 8 abut against the fixing plate 2 and the connecting plate 9 respectively.

[0040] In this technical solution, threaded grooves 4 are provided inside the four connecting rods 3.

[0041] In this technical solution, each of the four threaded grooves 4 is internally threaded with a threaded post 13.

[0042] In this technical solution, a limiting plate 14 is fixedly installed on each of the four threaded posts 13.

[0043] In use, the material to be screened enters the device through the feed pipe 1. During the fall of the material, it comes into contact with the two dustproof plates 15 and is subjected to pressure, which pushes the dustproof plates 15 to rotate around the rotating shaft 5. When the dustproof plates 15 rotate, they drive the movable plates 12 at both ends to rotate synchronously. The connecting shaft 7 in the movable groove 6 inside the movable plate 12 slides along the slide groove 11 and rotates at the same time, thereby driving the rotating plate 10 to rotate. The rotating plate 10 then drives the connecting rod 3 to move downward through the connecting plate 9. The connecting rod 3 slides downward along the through hole of the fixed plate 2. At the same time, the connecting plate 9 compresses the spring 8. After the material continues to pass through, the spring 8 pushes the connecting plate 9 to reset. Then, through the rotating plate 10, the connecting shaft 7, and the movable plate 12, the dustproof plate 15 rotates around the rotating shaft 5 to close, which can immediately block the feed pipe 1 and prevent the dust generated during the vibrating screen from spreading outward from the feed pipe 1. This achieves a highly efficient dust prevention effect and ensures a clean working environment and the health of the operators.

[0044] When the elasticity of spring 8 decreases after long-term use, rotate the limiting plate 14 until the threaded post 13 on the limiting plate 14 disengages from the connecting rod 3, thereby separating the limiting plate 14 from the connecting rod 3. After releasing the limiting, push the connecting rod 3 through the through hole of the fixing plate 2 upwards, and the old spring 8 can be removed for replacement. There is no need to disassemble the overall structure, which simplifies the spring 8 replacement process, reduces maintenance difficulty and time consumption, and extends the overall service life of the device.

[0045] The advantages of this application are:

[0046] 1. As the material falls, it comes into contact with the two dustproof plates 15 and is subjected to pressure. The connecting plate 9 compresses the spring 8. After the material continues to pass through, the spring 8 pushes the connecting plate 9 to reset. Then, through the rotating plate 10, the connecting shaft 7, and the movable plate 12, the dustproof plates 15 are driven to rotate around the rotating shaft 5 and close. This can immediately block the feed pipe 1 and prevent the dust generated during the vibrating screen from spreading outward from the feed pipe 1, thus playing a highly efficient dustproof role and ensuring a clean working environment and the health of the operators.

[0047] 2. By rotating the limiting plate 14 until the threaded post 13 on the limiting plate 14 disengages from the connecting rod 3, the limiting plate 14 and the connecting rod 3 are separated. After the limiting is released, the connecting rod 3 is pushed upward through the through hole of the fixing plate 2, and the old spring 8 can be removed for replacement. There is no need to disassemble the overall structure, which simplifies the spring 8 replacement process, reduces maintenance difficulty and time consumption, and extends the overall service life of the device.
