Description

Technical Field

[0001] This utility model belongs to the technical field of scraper conveyors, and in particular relates to a dustproof and leak-proof sealing structure for scraper conveyors. Background Technology

[0002] In modern industrial production, scraper conveyors are key equipment for material handling and are widely used in many fields such as coal, mining, metallurgy, and chemical industry. Their operational stability and sealing performance are crucial to production efficiency, material loss, and maintaining a good working environment. The dustproof and leak-proof sealing structure of scraper conveyors is a key component to ensure their good operation, and its performance directly affects the overall efficiency of the scraper conveyor.

[0003] However, the existing dustproof and leak-proof sealing structure of scraper conveyors is not convenient to compensate for scraper wear during use. With long-term operation, the bottom of the scraper will lose coal due to friction with the machine casing. This will lead to coal leakage, material waste, pollution of the working environment, and a reduction in the service life of the scraper, as well as an increase in the workload and cost of frequent scraper replacement. Utility Model Content

[0004] The purpose of this utility model is to provide a dustproof and leak-proof sealing structure for scraper conveyors. By setting an elastic compensation part, it solves the problem that the existing dustproof and leak-proof sealing structures for scraper conveyors are not convenient to compensate for scraper wear during use. Over long-term operation, the bottom of the scraper will wear down due to friction with the machine casing, which will lead to coal leakage, material waste, and pollution of the working environment. At the same time, it will reduce the service life of the scraper and increase the workload and cost of frequent scraper replacement.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a dustproof and leak-proof sealing structure for scraper conveyors, including a housing, and also including:

[0007] The system includes a conveying section housed within a chassis; a plurality of elastic compensation sections, each mounted on the conveying section; and an adjusting section, also comprising a plurality of adjusting sections mounted on the elastic compensation sections. Each adjusting section is adapted to one of the elastic compensation sections, and is used to adjust the elasticity of the elastic compensation sections.

[0008] Furthermore, the conveying unit includes two rotating shafts rotatably connected to the inner wall of the housing, two sprockets fixedly connected to the outer walls of the two rotating shafts, two chains arranged on the sprockets, a motor fixedly connected to the front side of the housing, and inlet and outlet components provided on the housing; wherein, the front side of the rotating shaft on the right extends to the outside of the housing, the two chains respectively mesh with the sprockets, and the output shaft of the motor is fixedly connected to the front extension of the rotating shaft on the left side through a coupling.

[0009] Furthermore, the elastic compensation part includes a scraper assembly disposed between two chains; and an elastic component disposed within the scraper assembly; wherein the elastic component is used to keep the bottom of the scraper assembly in close contact with the bottom inner wall of the chassis.

[0010] Furthermore, the adjusting part includes a limiting component mounted on the scraper assembly; and a spring-loaded component mounted on the top of the scraper assembly; wherein the limiting component and the spring-loaded component cooperate to ensure that the elastic compensation part remains stable during the operation of the conveying part. Furthermore, the scraper assembly includes a U-shaped shell fixedly connected between two chains, a connecting plate slidably connected to the inner wall of the U-shaped shell, two rectangular plates slidably connected to the inner wall of the connecting plate, and scrapers fixedly connected to the bottom of the two rectangular plates; wherein rectangular grooves are provided on the left and right sides of the connecting plate, and the two rectangular plates are slidably connected to the connecting plate through the two rectangular grooves respectively.

[0011] Furthermore, the elastic component includes two U-shaped rods fixedly connected to the bottom of the connecting plate. Several spring plates are slidably connected to the outer walls of the two U-shaped rods. Several connecting blocks are fixedly connected to the spring plates. The bottom of each connecting block is fixedly connected to the scraper. The bottom inner wall of the chassis is an arc-shaped design adapted to the chain. The bottom of the scraper has the same design, so that the scraper corresponding to the conveyor is squeezed by the arc-shaped inner wall of the chassis and slides towards the connecting plate when the conveyor is running.

[0012] Furthermore, the limiting component includes a threaded rod rotatably connected to the top of the U-shaped shell, a cylindrical shell rotatably connected to the outer wall of the threaded rod, the bottom of the cylindrical shell being fixedly connected to the U-shaped shell, a plurality of limiting grooves being opened on the inner wall of the U-shaped shell, and a ring being fixedly connected to the outer wall of the threaded rod; wherein, the bottom of the threaded rod extends into the U-shaped shell and the thread penetrates the connecting plate.

[0013] Furthermore, the rebound assembly includes several connecting blocks II fixedly connected to the ring, and each of the several connecting blocks II is fixedly connected to a spring telescopic rod on the side away from the threaded rod, and each of the several spring telescopic rods is fixedly connected to a limit block on the side away from the limit block; wherein, the several connecting blocks II are distributed in a circumferential array on the ring, and the several limit blocks are adapted to several limit grooves.

[0014] Furthermore, the feeding and discharging components include a feeding port on the top of the chassis and a discharging port on the bottom of the chassis; wherein both the feeding port and the discharging port are connected to the inner cavity of the chassis, and the length of the discharging port is slightly less than the width of the inner wall of the bottom of the chassis, so that the scraper passes smoothly through the discharging port.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up an elastic compensation part, when in use, the motor is turned on, and the motor drives the two corresponding sprockets to rotate through the rotating shaft fixedly connected to it. The two sprockets drive the two chains to rotate, thereby causing the elastic compensation part to rotate with the two chains. The bottom of the corresponding scraper will rub against the bottom of the machine box. After wear occurs, several spring plates will deform, thereby driving the scraper to move away from the connecting plate through several connecting blocks, so that it is always in close contact with the bottom inner wall of the machine box. When adjusting the elasticity of the elastic component, the threaded rod is rotated. The threaded rod drives the connecting plate to slide away from the cylindrical shell in the rectangular plate, thereby compressing and deforming several spring plates, replenishing their elasticity, and keeping the bottom of the scraper in close contact with the bottom inner wall of the machine box, thus forming an effective sealing structure, preventing coal leakage, material waste, and pollution of the working environment, extending the service life of the scraper, and reducing the workload and cost of frequent scraper replacement.

[0017] 2. By setting an adjustment part, when the threaded rod is rotated, the corresponding spring telescopic rod is squeezed by the limiting groove and moves continuously on different limiting grooves. The corresponding spring telescopic rod will contract or stretch until the adjustment is completed. The limiting block will be locked in the corresponding limiting groove by the elastic force of the spring telescopic rod to prevent the threaded rod from rotating accidentally. This allows the elasticity of the spring plate to be adjusted, reducing excessive wear caused by poor contact between the scraper and the bottom of the chassis, thereby reducing the frequency of maintenance and replacement of the scraper and chassis.

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.

[0029] Please see Figure 1-6As shown, this utility model is a dustproof and leak-proof sealing structure for scraper conveyors, including a housing 101, and further including: a conveying section 1, which is disposed inside the housing 101; several elastic compensation sections 2, each disposed on the conveying section 1; and several adjusting sections 3, each mounted on one of the elastic compensation sections 2; wherein the adjusting sections 3 are adapted to the elastic compensation sections 2, and the adjusting sections 3 are used to adjust the elasticity of the elastic compensation sections 2. The conveying section 1 includes two rotating shafts 102 rotatably connected to the inner wall of the housing 101, and two sprockets 103 are fixedly connected to the outer wall of each of the two rotating shafts 102. Two chains 104 are provided, and a motor 105 is fixedly connected to the front side of the housing 101. The housing 101 has inlet and outlet components. The front side of the rotating shaft 102 on the right side extends to the outside of the housing 101. The two chains 104 are respectively engaged with several sprockets 103. The output shaft of the motor 105 is fixedly connected to the front extension of the rotating shaft 102 on the left side through a coupling. The inlet and outlet components include an inlet 106 opened at the top of the housing 101 and an outlet 107 opened at the bottom of the housing 101. Both the inlet 106 and the outlet 107 are connected to the inner cavity of the housing 101. The length of the outlet 107 is slightly less than the width of the inner wall at the bottom of the housing 101, so that the scraper 214 can pass smoothly through the outlet 107.

[0030] The elastic compensation unit 2 includes a scraper assembly 21 disposed between two chains 104; and an elastic component 22 disposed within the scraper assembly 21. The elastic component 22 is used to keep the bottom of the scraper assembly 21 in close contact with the bottom inner wall of the chassis 101. The scraper assembly 21 includes a U-shaped shell 211 fixedly connected between the two chains 104. A connecting plate 212 is slidably connected to the inner wall of the U-shaped shell 211. Two rectangular plates 213 are slidably connected to the inner wall of the connecting plate 212. Scrapers 214 are fixedly connected to the bottom of the two rectangular plates 213. Rectangular grooves are provided on both the left and right sides of the connecting plate 212. The two rectangular plates 213 are slidably connected to the connecting plate 212 through the two rectangular grooves. The elastic component 22 includes two U-shaped... The outer walls of the two U-shaped rods 221 are slidably connected to several spring plates 222. Several connecting blocks 223 are fixedly connected to the spring plates 222. The bottom of each connecting block 223 is fixedly connected to the scraper 214. The bottom inner wall of the housing 101 is designed to fit the arc shape of the chain 104. The bottom of the scraper 214 has the same design. When the conveying unit 1 is running, the corresponding scraper 214 is squeezed by the arc inner wall of the housing 101 and slides towards the connecting plate 212. By setting the elastic compensation part 2, the bottom of the scraper 214 is always in close contact with the bottom inner wall of the housing 101, thereby forming an effective sealing structure to prevent coal leakage, material waste, and pollution of the working environment. This extends the service life of the scraper 214 and reduces the workload and cost of frequently replacing the scraper 214.

[0031] The adjusting part 3 includes a limiting component 31, which is mounted on the scraper assembly 21; and a spring-loaded component 32, which is mounted on the top of the scraper assembly 21. The limiting component 31 and the spring-loaded component 32 cooperate to ensure that the elastic compensation part 2 remains stable during the operation of the conveying part 1. The limiting component 31 includes a threaded rod 311 rotatably connected to the top of the U-shaped shell 211. A cylindrical shell 312 is rotatably connected to the outer wall of the threaded rod 311. The bottom of the cylindrical shell 312 is fixedly connected to the U-shaped shell 211. Several limiting grooves 313 are provided on the inner wall of the U-shaped shell 211. A ring 314 is fixedly connected to the outer wall of the threaded rod 311. The bottom of the threaded rod 311 extends into the U-shaped shell 211 and is threaded... The spring-loaded assembly 32, which passes through the connecting plate 212, includes several connecting blocks 321 fixedly connected to the ring 314. Each connecting block 321 has a spring telescopic rod 322 fixedly connected to the side away from the threaded rod 311, and each spring telescopic rod 322 has a limit block 323 fixedly connected to the side away from the limit block 323. The connecting blocks 321 are arranged in a circumferential array on the ring 314, and the limit blocks 323 are adapted to the limit grooves 313. By setting the adjustment part 3, the elasticity of the spring sheet 222 can be adjusted, reducing excessive wear caused by poor contact between the scraper 214 and the bottom of the chassis 101, thereby reducing the frequency of maintenance and replacement of the scraper 214 and the chassis.

[0032] A specific application of this embodiment is as follows: In use, when the motor 105 is turned on, the motor 105 drives the two corresponding sprockets 103 to rotate via the rotating shaft 102 fixedly connected to it. The two sprockets 103 drive the two chains 104 to rotate, thereby causing the elastic compensation part 2 to rotate with the two chains 104. The bottom of the corresponding scraper 214 will rub against the bottom of the chassis 101. After wear occurs, several spring plates 222 will deform, thereby driving the scraper 214 to move away from the connecting plate 212 through several connecting blocks 223, so that it is always in close contact with the bottom inner wall of the chassis 101. When adjusting the elasticity of the elastic component 22, the threaded rod 311 is rotated. The threaded rod 311 drives the connecting plate 212 to slide away from the cylindrical shell 312 within the rectangular plate 213. This causes several spring plates 222 to be compressed and deformed, thus replenishing their elasticity. During this process, the corresponding spring telescopic rod 322 is compressed by the limiting groove 313 and moves continuously on different limiting grooves 313. The corresponding spring telescopic rod 322 undergoes contraction or extension until the adjustment is completed. The limiting block 323 will be locked in the corresponding limiting groove 313 by the elastic force of the spring telescopic rod 322, preventing the threaded rod 311 from rotating accidentally.
