Description

Technical Field

[0001] This invention relates to the field of conveyor equipment technology, and in particular to a belt self-cleaning device. Background Technology

[0002] With the continuous advancement of industrialization, belt conveyor systems have been widely used in industries such as mining, chemical engineering, food processing, and logistics. Belt conveyor systems, with their high-efficiency material handling capacity, low operating costs, and ease of maintenance, have become an indispensable component of modern industrial production. In particular, the application of belt cleaning devices in belt conveyor systems used in environments such as coal mines is crucial. These devices are mainly used to remove coal dust, mud, powdery materials, etc., adhering to the surface of the belt during transportation, preventing material dust and equipment wear, reducing material accumulation under the belt, lowering equipment failure rates, and improving transportation efficiency.

[0003] Belt cleaning equipment mainly includes sweepers, spray systems, and scraper conveyors. Sweepers are a key component of belt conveyors, used to remove material adhering to the conveyor belt surface, preventing dust and equipment wear. Their function is to reduce material accumulation on the belt, lower equipment failure rates, and improve transport efficiency. The spray system sprays medium-pressure water onto the belt surface, and then uses multi-stage sweepers to scrape away and dry the material adhering to the belt surface, solving the problem of material carried on the return belt, reducing dust in the conveyor head area, lowering safety hazards such as fires, and promoting energy recovery. The scraper conveyor collects the material cleaned from the belt and pushes it back to the main chute or collection area, achieving material recycling. Scraper conveyors often use a recovery chain to drive scrapers to recover material, replacing manual cleaning and achieving the ultimate purpose of cleaning the material.

[0004] In existing belt self-cleaning equipment, the scraper conveyor typically remains in a lateral position during the return stroke after pushing the material. This causes the falling material to directly impact the scraper during the return stroke, potentially damaging it or affecting its cleaning effect. The impact of the moving scraper on the falling material during the return stroke also causes the material to scatter, affecting recycling efficiency and polluting the surrounding environment. Furthermore, due to the lack of an effective self-cleaning mechanism, material easily adheres to the scraper surface during the scraper's return stroke. This not only increases the equipment's energy consumption but may also lead to poor cleaning results during the next push. Therefore, those skilled in the art have provided a belt self-cleaning equipment to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to address the problems of existing belt self-cleaning equipment where, during actual use, the return scraper is located on the path of the falling material, which easily increases equipment wear and causes material spillage. Furthermore, the return scraper cannot achieve self-cleaning, and the large amount of material adhering to its surface during the return stroke increases equipment energy consumption and affects the cleaning effect of the next cycle. Therefore, this invention proposes a belt self-cleaning equipment.

[0006] To achieve the above objectives, the present invention employs the following technology: a belt self-cleaning device comprising: A conveying module, the conveying module including a chain conveying mechanism set inside the equipment box, and two sets of rotating rods connected to the chain conveying mechanism are rotatably installed inside the equipment box, one set of rotating rods having a drive component connected to its end; An adjustment module includes a positioning bracket mounted on a chain conveyor and a retainer rotatable on the positioning bracket. A scraper body is fixedly mounted on one side of the retainer. An adjustment bracket extending into the retainer is slidably mounted on the positioning bracket. A limiting slide is installed inside the equipment box to control the movement of the adjustment bracket relative to the positioning bracket. The adjustment bracket slides within the positioning bracket to control the rotation of the retainer relative to the positioning bracket. The self-cleaning module includes an elastic adjustment mechanism installed inside the retainer. The elastic adjustment mechanism abuts against the end of the adjustment bracket. The elastic adjustment mechanism is connected to a cleaning mechanism for scraping off the surface of the scraper body via a connecting rod.

[0007] As a further description of the belt self-cleaning device described above: The chain conveyor mechanism includes two sets of parallel chains. Each set of rotating rods is equipped with two sets of sprockets that mesh with the chains. The positioning bracket is installed on the two sets of chains.

[0008] As a further description of the belt self-cleaning device described above: The positioning bracket includes connecting blocks fixedly installed on the chain. Two sets of connecting blocks on the chain are fixedly connected to a frame plate by bolts. The bottom of the frame plate is fixedly installed with a support ring by two sets of support blocks.

[0009] As a further description of the belt self-cleaning device described above: The retainer includes a support box fixedly connected to the scraper body. Two sets of vertical rods slidably connected to the support ring are fixedly installed on the top of the support box. A lever is fixedly installed on the opposite surface of the two sets of vertical rods.

[0010] As a further description of the belt self-cleaning device described above: The adjusting bracket includes a slide rod that is slidably connected to the frame plate. One end of the slide rod is fixedly installed with a linkage shaft that abuts against the elastic adjusting mechanism. The outer ring of the linkage shaft is provided with a spiral groove for the end of the lever to slide. Rollers extending into the limiting slide are rotatably installed on both sides of the other end of the slide rod.

[0011] As a further description of the belt self-cleaning device described above: The limiting slide includes a slide body that is rotatably connected to two sets of rotating rods. The slide body is installed between two sets of chains, and one side of the slide is fixedly connected to the equipment box through multiple sets of support rods. The slide body has a limiting groove inside for the displacement of the rollers.

[0012] As a further description of the belt self-cleaning device described above: The limiting chute includes a first straight section, a first ramp section, a second straight section, and a second ramp section. When the roller moves into the first straight section, the adjusting bracket controls the retainer and scraper body to be in a horizontally arranged pushing material state. When the roller moves into the second straight section, the adjusting bracket controls the retainer and scraper body to be in a longitudinally arranged return state. The first ramp section is used to adjust the retainer and scraper body from a horizontal arrangement to a longitudinal arrangement, and the second ramp section is used to adjust the retainer and scraper body from a longitudinal arrangement to a horizontal arrangement.

[0013] As a further description of the belt self-cleaning device described above: The elastic adjustment mechanism includes two sets of support rods fixedly installed inside the support box. Movable plates that abut against the ends of the linkage shaft are slidably installed on the two sets of support rods. A spring sleeved on the outer ring of the support rod is fixedly installed between the movable plate and the inner wall of the support box. A mounting block that is hinged to the end of the connecting rod is fixedly installed on the side of the movable plate away from the linkage shaft.

[0014] As a further description of the belt self-cleaning device described above: The cleaning mechanism includes a crossbar welded to the outside of the support box, a movable rod slidably mounted on the crossbar, and multiple sets of scraper strips that conform to the surface of the scraper body fixedly mounted on the movable rod. The side of the scraper strips near the support box is hinged to the end of the connecting rod.

[0015] As a further description of the belt self-cleaning device described above: The equipment box has two sets of chain conveyor mechanisms installed symmetrically on the left and right sides. Each set of chain conveyor mechanisms is equipped with multiple sets of adjustment modules, and the adjustment modules on the two sets of chain conveyor mechanisms are staggered front and back.

[0016] In summary, due to the adoption of the above-mentioned technology in the belt self-cleaning device, the beneficial effects of this invention are: By setting an adjustment module in conjunction with the limiting slide, the scraper body can be automatically rotated and adjusted to fold into the outer ring of the chain conveyor when it needs to return after completing one material push. After adjustment, the scraper body can stay away from the path of material fall during the return, which can prevent material from directly hitting the scraper during the return process, reduce material scattering due to impact, thereby improving material collection efficiency, reducing wear on the scraper body due to impact, extending the scraper's service life, and reducing the overall maintenance cost of the equipment. In addition, during the rotation adjustment process, the external self-cleaning module can automatically clean the adhering substances on its surface, thereby maintaining the cleanliness of the scraper body and ensuring the cleaning efficiency of the next push. It also helps to avoid unnecessary energy consumption of the equipment due to the adhering substances on the scraper body surface. Attached Figure Description

[0019] The following will describe, with reference to the accompanying drawings of the embodiments of the present invention, a belt self-cleaning device according to the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-9 As shown, the present invention provides a belt self-cleaning device, including a conveying module 20 and an adjusting module 30, etc. The conveying module 20 includes a chain conveying mechanism 201 disposed inside the equipment box 10. Two sets of rotating rods 202 connected to the chain conveying mechanism 201 are rotatably installed inside the equipment box 10. The end of one set of rotating rods 202 is connected to a driving component. The driving component can be a motor plus a gearbox commonly used in the prior art, used to control the rotation of the rotating rods 202 connected to it. The rotating rods 202 drive the chain conveying mechanism 201 to run and the other set of rotating rods 202 to rotate.

[0021] The adjustment module 30 includes a positioning bracket 301 mounted on the chain conveyor mechanism 201 and a retainer 302 that can rotate on the positioning bracket 301. A scraper body 11 is fixedly mounted on one side of the retainer 302. An adjustment bracket 303 extending into the retainer 302 is slidably mounted on the positioning bracket 301. A limiting slide 40 for controlling the movement of the adjustment bracket 303 relative to the positioning bracket 301 is installed inside the equipment box 10. The adjustment bracket 303 slides within the positioning bracket 301 to control the rotation of the retainer 302 relative to the positioning bracket 301.

[0022] In practical applications, the equipment can be used in combination with existing components such as sweepers and spray systems. The sweeper and spray system are assembled below the return of the conveyor belt to clean the return material. The equipment provided in this technical solution can be installed directly below the sweeper and spray system. The material cleaned from the conveyor belt can fall into the interior of the equipment box 10. The operation of the chain conveyor mechanism 201 can drive the positioning bracket 301 installed on it to move. The positioning bracket 301 drives the adjusting bracket 303 and the retainer 302 to move together. When the scraper body 11 moves against the bottom plate of the inner cavity of the equipment box 10, it can... The internal material is pushed to the main chute or collection area at the front of the equipment. When the chain conveyor mechanism 201 controls the scraper body 11 to move to the return path, the adjusting bracket 303 can slide relative to the positioning bracket 301 due to the limitation of the limiting slide 40, thereby making the retainer 302 and the scraper body 11 rotate to be parallel to the conveying direction. After the scraper body 11 is adjusted to both sides of the inner cavity of the equipment box 10, it can effectively avoid contact with the material during the return process. After the scraper body 11 moves to the rear end of the equipment box 10 and needs to be pushed again, it can be automatically adjusted to be perpendicular to the conveying direction for efficient material pushing.

[0023] The further self-cleaning belt cleaning equipment also has a self-cleaning module 50, which includes an elastic adjustment mechanism 501 installed inside the retainer 302. The elastic adjustment mechanism 501 abuts against the end of the adjustment bracket 303. The elastic adjustment mechanism 501 is connected to a cleaning mechanism 502 for scraping off the surface of the scraper body 11 via a connecting rod 12. When the limiting slide 40 controls the retainer 302 and the scraper body 11 to rotate and adjust, the limiting slide 40 can simultaneously drive the elastic adjustment mechanism 501 to extend and retract. The moving elastic adjustment mechanism 501 can drive the cleaning mechanism 502 to slide on the scraper body 11 via the connecting rod 12. The moving cleaning mechanism 502 can efficiently remove the attachments on the surface of the scraper body 11, so as to facilitate the efficient pushing of the scraper body 11 in the next cycle.

[0024] The chain conveyor mechanism 201 includes two sets of parallel chains 2011. Each set of rotating rods 202 is equipped with two sets of sprockets 2012 that mesh with the chains 2011. The positioning bracket 301 is installed on the two sets of chains 2011. The two sets of parallel chains 2011 are provided to support and convey the positioning bracket 301 and its connecting structure, which can improve the overall stability of the positioning bracket 301 and its connecting structure when moving. The top of the equipment box 10 can be provided with an inwardly folded baffle to prevent the material being fed from affecting the normal operation of the chain conveyor mechanism 201.

[0025] In one embodiment, such as Figures 3-9As shown, specifically, the positioning bracket 301 includes a connecting block 3011 fixedly installed on the chain 2011. The connecting blocks 3011 on the two sets of chains 2011 are fixedly connected to the frame plate 3012 by bolts. The bottom of the frame plate 3012 is fixedly installed with a support ring 3013 by two sets of support blocks 3014. The support blocks 3014 can be directly welded to their connecting components. The support ring 3013 is used to provide rotational support for the retainer 302. The frame plate 3012 is detachably connected to the connecting block 3011, which allows for flexible maintenance and replacement when the adjustment module 30 component is damaged.

[0026] Correspondingly, the retainer 302 includes a support box 3021 fixedly connected to the scraper body 11. Two sets of vertical rods 3022 slidably connected to the support ring 3013 are fixedly installed on the top of the support box 3021. A lever 3023 is fixedly installed on the opposite surface of the two sets of vertical rods 3022. The fixed connections between the components can be directly welded or detachably connected by bolts. The lever 3023 is used to enable the retainer 302 as a whole to rotate relative to the adjustment bracket 303 when the bracket 303 is displaced.

[0027] To achieve periodic rotational adjustment of the retainer 302 and the scraper body 11, specifically, the adjustment bracket 303 includes a slide rod 3031 slidably connected to the bracket plate 3012. One end of the slide rod 3031 is fixedly installed with a linkage shaft 3032 that abuts against the elastic adjustment mechanism 501. The outer ring of the linkage shaft 3032 is provided with a spiral groove 3033 for the end of the lever 3023 to slide. Both sides of the other end of the slide rod 3031 are rotatably installed with rollers 3034 extending into the limiting slide 40.

[0028] When the roller 3034 slides within the limiting slide 40 and generates displacement relative to the frame plate 3012, the roller 3034 can drive the slide rod 3031 to slide inside the frame plate 3012. The slide rod 3031 can drive the linkage shaft 3032 at the bottom to move together. The movement of the linkage shaft 3032 can control the lever 3023 to rotate and adjust in the horizontal plane through the spiral groove 3033 set on its outer ring. The lever 3023 can drive the vertical rod 3022 to rotate and slide on the support ring 3013. The vertical rod 3022 can drive the support box 3021, scraper body 11 and other structures to rotate and adjust together. This enables the chain conveyor mechanism 201 to automatically control the scraper body 11 to rotate and adjust at a fixed position during normal operation.

[0029] Based on the above embodiments, such as Figures 1-6As shown, specifically, the limiting slide 40 includes a slide body 401 that is rotatably connected to both sets of rotating rods 202. The slide body 401 is installed between two sets of chains 2011, and one side of the slide is fixedly connected to the equipment box 10 through multiple sets of support rods 402. One end of the support rod 402 can be directly welded to the slide body 401, and the other end of the support rod 402 can be detachably connected to the equipment box 10 by bolts. The slide body 401 has a limiting slide groove 403 inside for the displacement of the roller 3034. In order to realize the automatic control of the scraper body 11 adjustment during the movement of the adjusting bracket 303 following the chain conveyor mechanism 201, the limiting slide groove 403 may include a first straight section 4031, a first ramp section 4032, a second straight section 4033, and a second ramp section 4034. The center of the slide body 401 is also provided with an active space for the slide rod 3031 to move along the outer ring of the limiting slide groove 403.

[0030] When the roller 3034 moves into the first straight section 4031, the adjusting bracket 303 controls the retainer 302 and scraper body 11 to be in a horizontally arranged pushing state, with the scraper body 11 perpendicular to the conveying direction. When the conveying roller 3034 moves into the second straight section 4033, the adjusting bracket 303 controls the retainer 302 and scraper body 11 to be in a longitudinally arranged return state, with the scraper body 11 parallel to the conveying direction. When the roller 3034 moves to the first ramp section 4032, it can adjust the retainer 302 and scraper body 11 from a horizontal arrangement to a longitudinal arrangement. When the roller 3034 moves to the second ramp section 4034, it can adjust the retainer 302 and scraper body 11 from a longitudinal arrangement to a horizontal arrangement.

[0031] In one embodiment, such as Figures 3-9 As shown, specifically, the elastic adjustment mechanism 501 includes two sets of support rods 5011 fixedly installed inside the support box 3021. Movable plates 5012 that abut against the end of the linkage shaft 3032 are slidably installed on the two sets of support rods 5011. A spring 5013 sleeved on the outer ring of the support rod 5011 is fixedly installed between the movable plate 5012 and the inner wall of the support box 3021. A mounting block 5014 that is hinged to the end of the connecting rod 12 is fixedly installed on the side of the movable plate 5012 away from the linkage shaft 3032. Correspondingly, the cleaning mechanism 502 includes a crossbar 5021 welded to the outside of the support box 3021. A movable rod 5022 is slidably installed on the crossbar 5021. Multiple sets of scraper strips 5023 that conform to the surface of the scraper body 11 are fixedly installed on the movable rod 5022. The side of the scraper strip 5023 near the support box 3021 is hinged to the end of the connecting rod 12.

[0032] When the scraper body 11 needs to be adjusted to the return state after completing one push, the movement of the linkage shaft 3032 can simultaneously drive the movable plate 5012 to slide on the support rod 5011. The movable plate 5012 also drives the installation block 5014 to move and the spring 5013 to extend and retract. The subsequent reset of the spring 5013 can control the return movement of the installation block 5014 and its connecting structure. The moving installation block 5014 can drive multiple sets of scraper blades 5023 and movable rods 5022 to move through the connecting rod 12. The crossbar 5021 can provide limit support for the movement of multiple sets of scraper blades 5023 and movable rods 5022. The scraper blades 5023 that move in contact with the surface of the scraper body 11 can remove the adhering substances on its surface, effectively reducing the burden on the scraper body 11 during the return stroke, and also helping to ensure the cleaning effect of the next push.

[0033] In one embodiment, such as Figures 1-3 As shown, two sets of chain conveyor mechanisms 201 are symmetrically installed inside the equipment box 10. Each set of chain conveyor mechanisms 201 is equipped with multiple sets of adjustment modules 30, and the adjustment modules 30 on the two sets of chain conveyor mechanisms 201 are staggered. The two sets of chain conveyor mechanisms 201 can more effectively convey and collect materials, better adapt to different working conditions and material characteristics, and improve the versatility and adaptability of the equipment.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technology of the belt self-cleaning device and its inventive concept, should be covered within the scope of protection of the present invention.
