Description

Technical Field

[0001] This invention belongs to the field of transmission equipment technology, specifically relating to a transmission belt anti-deviation device and its usage method. Background Technology

[0002] Belt conveyors are mainly composed of drive, load-bearing, traction, and tensioning mechanisms. They are a continuous transport system that uses rubber or nylon conveyor belts to transport materials. They can transport loose materials horizontally or at an incline, as well as transport packaged goods.

[0003] It is a core component of large machinery such as ship loaders, stackers, and bucket wheel stacker-reclaimers, and as a separate continuous bulk material transport system, it has been widely used in various industries such as coal transportation, ports, power plants, mines, metallurgy, and grain.

[0004] Rubber or nylon conveyor belts, also known as belts, serve to provide traction and load-bearing functions. Belt conveyors include belt drive rollers, belt driven rollers, buffer idler groups, return belt pressure rollers, and a transmission belt (belt or conveyor belt). The belt runs around the belt drive rollers, buffer idler groups, belt driven rollers, and return belt pressure rollers, transporting materials placed on the belt from one place to another.

[0005] The stability and reliability of the conveyor belt are crucial. However, belt misalignment is inevitable during operation due to factors such as equipment manufacturing, installation, and uneven material distribution along the belt width. Severe misalignment can directly damage the belt and paralyze the equipment. Belt misalignment is the most common abnormality in conveyor systems, and its causes are numerous and difficult to manage.

[0006] Currently, when the conveyor belt is not misaligned, the side of the conveyor belt does not contact the surface of the anti-deviation roller, thus preventing wear on the side of the conveyor belt and the surface of the anti-deviation roller. However, once the conveyor belt deviates, the side of the conveyor belt will contact the surface of the anti-deviation roller, resulting in friction and wear. This wear will continue for a long section of the conveyor belt. If the misalignment is not corrected quickly, the two sides of the conveyor belt will become uneven. In severe cases, the conveyor belt may tip over or break, causing coal to spill and be difficult to clean. Moreover, the worn conveyor belt requires shutdown for replacement, which is time-consuming and inefficient, wasting conveyor belt resources. Simultaneously, the friction and wear between the conveyor belt and other structures such as the drive roller during transmission generates high temperatures, causing the conveyor belt to stretch due to heat. This makes the conveyor belt loosen, increasing the likelihood of deviation, damaging the conveyor belt, and even causing coal slag to spontaneously combust due to heat.

[0007] Therefore, it is necessary to design a conveyor belt anti-deviation device and its usage method to solve the problem of conveyor belt deviation. Summary of the Invention

[0008] To address some or all of the aforementioned technical problems in the prior art, this invention proposes a conveyor belt anti-deviation device and its usage method. This anti-deviation device can repair and reset a misaligned conveyor belt, preventing damage to the conveyor belt.

[0009] According to one aspect of the present invention, a conveyor belt anti-deviation device is provided, comprising: support platform A rotating plate positioned above the support platform. A first support plate is disposed above the rotating plate, and there are two first support plates arranged at a lateral interval. A drive roller is rotatably disposed between the first support plates, and the drive roller is used to be disposed on the bottom side of the outgoing conveyor belt in the conveyor belt. A first rotating rod is rotatably disposed between the first support plates, and the first rotating rod is pulsatorically connected to the transmission roller to rotate under the drive of the transmission roller. A cam plate is fixedly mounted on the first rotating rod, and the cam plate is located laterally outside the first support plate. The rotating plate has two uprights, which are spaced apart laterally and located on the outer side of the first support plate. Anti-deviation rollers are rotatably fitted onto the outer wall of each of the uprights. A third limiting plate is fixedly sleeved on the anti-deviation roller. A lower buffer plate, intermittently fitted onto the anti-deviation roller, is located above the third limiting plate and extends laterally to the bottom side of the outgoing conveyor belt. An actuating plate is intermittently fitted onto the anti-deviation roller, the actuating plate being located between the lower buffer plate and the third limiting plate. A spacer is intermittently fitted onto the anti-deviation roller, the spacer being located between the jacking plate and the third limiting plate. A fourth spring is disposed between the gasket and the actuating plate. A guide rod that passes intermittently through the top moving plate and is fixed to the lower buffer plate. A second spring is sleeved on the guide rod and located between the lower buffer plate and the top plate.

[0010] In one embodiment, an upper buffer plate is intermittently sleeved on each of the anti-deviation rollers, and the upper buffer plate and the corresponding lower buffer plate are spaced apart axially on the anti-deviation rollers to clamp the side of the outgoing conveyor belt in the conveyor belt. A first limiting plate is intermittently sleeved on the outer wall of each of the uprights. The first limiting plate is located above the anti-deviation roller and is fixedly connected to the upper buffer plate. A second limiting plate is fixedly installed at the top of the pole, and a first spring is provided between the second limiting plate and the first limiting plate.

[0011] In one embodiment, the device further includes an abrasion-resistant edge for being disposed on the side of the conveyor belt. The abrasion-resistant edge has a first insertion groove on its side for insertion into the side of the conveyor belt. An insertion strip is fixed to the bottom of the first insertion groove. The insertion strip is used to insert into a second insertion groove disposed on the side of the conveyor belt. A positioning groove is formed on one end wall of the second insertion groove. A positioning post is fixed on the insertion strip and is inserted into the positioning groove.

[0012] In one embodiment, a tensile-resistant strip extending along the length of the conveyor belt is provided within the connector strip.

[0013] In one embodiment, a rotating column is fixed at the bottom center of the rotating plate, and a positioning sleeve is fixed at the top of the support platform. The rotating column is slidably and rotatably inserted into the inner cavity of the positioning sleeve. A guide plate is fixed at the top of the support platform and at a position outside the positioning sleeve. A guide groove is opened in the middle of the guide plate. A guide column extending into the guide groove is fixed at the bottom of the rotating plate. Connecting holes are opened on both sides of the guide column. A sliding groove is opened on the side of the guide plate. A limiting bolt passes through the inside of the sliding groove, and the inner end of the limiting bolt is threaded into the connecting hole.

[0014] In one embodiment, baffles are fixed at both ends of the support platform in the horizontal direction, and actuating rods are fixed at both ends of the rotating plate. A second guide hole is opened on the surface of the baffle, and a buffer rod passes through the inside of the second guide hole. An abutment plate is fixed at the inner end of the buffer rod, and the abutment plate abuts against both sides of the actuating rod. A third spring is slidably sleeved on the surface of the buffer rod at a position between the baffle and the abutment plate.

[0015] In one embodiment, a first fan blade and a first cleaning brush are spaced apart on the surface of the first rotating rod.

[0016] In one embodiment, two second support plates are fixed at the bottom of the support platform, which are laterally spaced apart. A cleaning roller for the bottom side of the return conveyor belt in the conveyor belt is rotatably installed between the second support plates. A left-handed cleaning strip and a right-handed cleaning strip are fixed at both ends of the surface of the cleaning roller.

[0017] In one embodiment, a second rotating rod is rotatably mounted between the second support plates, the second rotating rod being located below the cleaning roller and being drive-connected to the cleaning roller.

[0018] According to another aspect of the present invention, a method of using a conveyor belt anti-deviation device is provided. When the conveyor belt deviates and one side is higher than the other, the lower buffer plate abuts against the lower side of the conveyor belt, and the rotating first rotating rod drives the cam plate to rotate intermittently to push the actuating plate, thereby pushing the lower side of the conveyor belt.

[0019] Compared with the prior art, the advantages of the present invention are as follows: the lower buffer plate of the conveyor belt anti-deviation device can extend to the bottom side of the conveyor belt. When the conveyor belt deviates, one side of the conveyor belt falls onto the lower buffer plate, which supports the conveyor belt and assists in its repositioning. In particular, the downward pressure of the conveyor belt is transmitted to the jacking plate, and the bottom side of the jacking plate is subjected to the intermittent jacking action of the cam, which facilitates vibration and pushing of the lower end of the conveyor belt, pushing the conveyor belt upward and further promoting its repositioning. In addition, due to the intermittent jacking action of the cam, materials such as coal at the edge of the conveyor belt can be vibrated and rolled into the inward recess of the conveyor belt, preventing coal from falling off. At the same time, the intermittent jacking action of the cam 8 on the conveyor belt 20 further promotes its repositioning. Furthermore, the intermittent jacking action of the cam can relatively reduce the friction between the outer edge of the conveyor belt 20 and the lower buffer plate 10, reducing wear on both sides of the conveyor belt 20 and improving its service life.

[0022] In the accompanying drawings, the same parts use the same reference numerals. The drawings are not drawn to scale. Detailed Implementation

[0023] To make the technical solutions and advantages of the present invention clearer, exemplary embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not an exhaustive list of all embodiments. Furthermore, without conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0024] Embodiments of the present invention provide a conveyor belt anti-deviation device. For example... Figures 1 to 13 As shown, the conveyor belt anti-deviation device includes a support platform 1. A rotating plate 22 is disposed above the support platform 1. The rotating plate 22 is planar and extends roughly parallel to the conveyor belt in actual use. A first support plate 7 is fixed to the top of the rotating plate 22. There are two first support plates 7, which are spaced apart in the transverse direction (consistent with the transverse direction of the conveyor belt, i.e., the width direction). A drive roller 19 is disposed between the two first support plates 7, and the drive roller 19 can rotate relative to the first support plate 7. During use, the drive roller 19 is disposed on the bottom side of the outgoing conveyor belt of the conveyor belt 20, i.e., below, so as to rotate under the drive of the conveyor belt 20. A first rotating rod 21 is disposed below the drive roller 19. A vertical rod 17 is fixed at the top of the rotating plate 22 and at a position outside the first support plate 7. An anti-deviation roller 12 is rotatably mounted on the surface of the vertical rod 17. After installation and use, the anti-deviation roller 12 is located on both sides of the conveyor belt 20. A second spring 34 is disposed below the lower buffer plate 10. A push plate 9 is provided at the bottom end of the second spring 34. Cam plates 8 are fixed at both ends of the first rotating rod 21. The cam plate 8 is vertically arranged on the outside of the first support plate 7 and located below the push plate 9. The top end of the cam plate 8 reciprocates to push the push plate 9. The lower buffer plate 10 is located at the bottom end of the edge of the conveyor belt 20. A third rotating hole 35 is opened in the middle of the lower buffer plate 10, and the anti-deviation roller 12 slides through the third rotating hole 35. The lower buffer plate 10 rotates around the anti-deviation roller 12 during the contact with the conveyor belt 20. A third limiting plate 39 is fixed at the bottom end of the surface of the anti-deviation roller 12. The push plate 9 is slidably installed on the top end of the third limiting plate 39 and can rotate around the surface of the anti-deviation roller 12. A fourth spring 68 is connected to the middle bottom end of the push plate 9. A washer 67 is connected to the bottom end of the fourth spring 68. The gasket 67 is slidably sleeved on the surface of the anti-deviation roller 12 and can rotate around the surface of the anti-deviation roller 12 by being driven by the fourth spring 68, pressing against the top of the third limiting plate 39. The lower buffer plate 10 is pushed upward by the fourth spring 68, the second spring 34 and the guide rod 38. The top plate 9 has a fourth rotating hole 40 in the middle. The anti-deviation roller 12 slides through the fourth rotating hole 40. The surface of the top plate 9 has a first guide hole 36. The bottom end of the lower buffer plate 10 is fixed with a guide rod 38. The guide rod 38 slides through the first guide hole 36. The second spring 34 is slidably sleeved on the surface of the guide rod 38 and is located between the lower buffer plate 10 and the top plate 9. The bottom end of the guide rod 38 is fixed with a fourth limiting plate 37.

[0025] An upper buffer plate 11 is also provided on the anti-deviation roller 12, so that it is located at the top of the conveyor belt 20 after installation. Specifically, the upper buffer plate 11 has a first rotating hole 32 in the middle, through which the anti-deviation roller 12 slides. The upper buffer plate 11 is located at the top edge of the conveyor belt 20. When the conveyor belt 20 is not deviating, the upper buffer plate 11 and the conveyor belt 20 are not in contact. After the conveyor belt 20 deviates, its higher side abuts against the upper buffer plate 11, causing the upper buffer plate 11 to rotate on the surface of the anti-deviation roller 12. A connecting rod 13 is fixed to the top of the upper buffer plate 11. A first limiting plate 14 is fixed to the top of the connecting rod 13 at the top of the anti-deviation roller 12. A second rotating hole 47 is opened in the middle of the first limiting plate 14. The upright 17 slides through the second rotating hole 47. The first limiting plate 14 is rotatably mounted on the top of the anti-deviation roller 12 and rotates around the upright 17. A second limiting plate 16 is fixed to the top of the upright 17. A first spring 15 is slidably sleeved on the surface of the upright 17 and located between the second limiting plate 16 and the first limiting plate 14. It provides cushioning for the upper buffer plate 11 and bounces downward to push the first limiting plate 14 and the upper buffer plate 11 to prevent the conveyor belt 20 from deviating excessively and to strengthen the correction of the deviated conveyor belt 20.

[0026] The surface of the anti-deviation roller 12 is fitted with an upper buffer plate 11 and a lower buffer plate 10, which are respectively set at the upper and lower ends of the side of the conveyor belt 20. When the conveyor belt 20 is transporting coal and there is no deviation, its two sides do not contact the upper buffer plate 11, the lower buffer plate 10, and the anti-deviation roller 12. When the conveyor belt 20 deviates, one side is higher than the other. The higher side pushes the upper buffer plate 11 upward and is cushioned by the downward pressure of the upper buffer plate 11 and the first spring 15, reducing the degree of upward deviation. The lower side presses the lower buffer plate 10 downward and is cushioned by the upward bounce of the lower buffer plate 10, the second spring 34, and the fourth spring 68, reducing the degree of downward deviation. At the same time, the first rotating rod 21 drives the cam plate 8 to rotate and intermittently pushes the jacking plate 9 upward, thereby strengthening the upward pushing force of the lower buffer plate 10 on the side of the conveyor belt 20, accelerating the correction and reset of the conveyor belt 20, reducing the degree of deviation, reducing the friction and wear on both sides of the conveyor belt 20, reducing coal spillage, and protecting the safe use of the conveyor belt 20.

[0027] The first rotating rod 21 is located below the anti-deviation roller 12 and is perpendicular to it. A first fan blade 46 and a first cleaning brush 45 are spaced apart on the surface of the first rotating rod 21. The first cleaning brush 45 contacts the surface of the transmission roller 19. The top of the transmission roller 19 slides over the conveyor belt 20. During the movement of the conveyor belt 20, the inner side of its top edge drives the transmission roller 19 to rotate, and the first rotating rod 21 drives the first fan blade 46 and the first cleaning brush 45 to rotate. The first fan blade 46 blows air onto the surface of the transmission roller 19 and the inner side of the top edge of the conveyor belt 20, dissipating the heat generated by friction, blowing away adhering dust and slag, and cooling the conveyor belt 20. This prevents the conveyor belt 20 from expanding and contracting due to heat, becoming loose, or even breaking. It also prevents the heat generated by friction from being conducted to the coal being transported via the conveyor belt 20, which could cause the coal to overheat and spontaneously combust. Furthermore, the first cleaning brush 45 cleans and scrubs the surface of the transmission roller 19, removing adhering slag.

[0028] The conveyor belt 20 has wear-resistant edges 33 on both sides. For example, the wear-resistant edges 33 are made of wear-resistant rubber. A first insertion groove 64 is formed on the side of the wear-resistant edge 33, into which the side of the conveyor belt 20 is inserted. An insertion strip 62 is fixed to the side of the first insertion groove 64. The insertion strip 62 is made of the same material as the wear-resistant edge 33. An anti-tensile strip 63 is provided inside the insertion strip 62. For example, the anti-tensile strip 63 is made of stainless steel wire and is wrapped inside the insertion strip 62. A second insertion groove 61 is formed on the side of the conveyor belt 20. After installation, the insertion strip 62 is inserted into the second insertion groove 61. A positioning groove 66 is formed at the bottom of the second insertion groove 61. For example, the positioning groove 66 is a circular groove structure, multiple in number, and evenly distributed along the length of the conveyor belt 20. Simultaneously, a positioning post 65 is fixed to the bottom of the insertion strip 62. The positioning post 65 is used to insert into the positioning groove 66. Understandably, multiple positioning posts 65 are also provided to match the positioning grooves 66. The positioning posts 65 can also be made of wear-resistant rubber. An anti-tensile strip 63 is installed inside the connector strip 62 to replace the wear on both sides of the conveyor belt 20, protecting the sides of the conveyor belt 20 and improving its tensile strength. This design allows for the quick removal of the anti-wear edge 33, connector strip 62, anti-tensile strip 63, and positioning posts 65 using hooks, flat blades, or other structures without stopping the movement of the conveyor belt 20. Then, the connector strip 62 is inserted into the second connector groove 61 to quickly install a new anti-wear edge 33, avoiding the disruption of coal transport by stopping the conveyor belt 20 and effectively reducing the time required for conveyor belt 20 maintenance.

[0029] A first mounting hole 43 is formed on the surface of the first support plate 7. A first bearing 44 is installed inside the first mounting hole 43. The first rotating rod 21 passes through the inner ring of the first bearing 44. It can be seen that the first bearing 44 is provided between the first rotating rod 21 and the first support plate 7 to ensure that the first rotating rod 21 rotates smoothly relative to the first support plate 7. A first driven gear 18 is installed on the outer wall of the first rotating rod 21 and near the inner side of the first support plate 7. A first rotating shaft 41 is installed at both ends of the transmission roller 19. The first rotating shaft 41 is rotatably connected to the top side of the first support plate 7. A first driving gear 42 is installed on the surface of the first rotating shaft 41. The first driving gear 42 meshes with the first driven gear 18 for transmission. It can be seen that the transmission roller 19 drives the first rotating rod 21 to move through the meshing of the first driving gear 42 and the first driven gear 18.

[0030] A rotating column 5 is fixed to the bottom center of the rotating plate 22. A positioning sleeve 2 is fixed to the top center of the support platform 1. The bottom end of the rotating column 5 is slidably and rotatably inserted into the interior of the positioning sleeve 2. The positioning sleeve 2 restricts the rotating column 5, thereby restricting the rotating plate 22. That is, the rotating column 5 can drive the rotating plate 22 to rotate around the axial direction of the positioning sleeve 2, but the rotating column 5 cannot slide on the top surface of the support platform 1 due to the restriction of the positioning sleeve 2, and therefore the rotating plate 22 cannot wobble relative to the support platform 1.

[0031] A guide plate 50 is fixed at the top of the support platform 1, located at both ends of the positioning sleeve 2. A guide groove 53 is formed in the middle of the guide plate 50. Both the guide plate 50 and the guide groove 53 are arc-shaped. A guide post 3 is fixed at the bottom of the rotating plate 22, located on both outer sides of the rotating post 5. The guide post 3 slides into the guide groove 53. Connecting holes 54 are formed on both sides of the guide post 3. The connecting holes 54 are threaded holes. A sliding groove 51 is formed on the side of the guide plate 50. The sliding groove 51 is arc-shaped and its length is less than the length of the guide plate 50. The interior of the sliding groove 51 is horizontal and slides through a limiting bolt 52. The inner end of the limiting bolt 52 is threaded into the connecting hole 54, limiting the guide post 3. This configuration allows the guide plate 50 to support the rotating plate 22, limiting the position of the rotating plate 22 relative to the support platform 1, and facilitating disassembly, installation, replacement, and maintenance of the rotating plate 22 and the support platform 1. In particular, the above-mentioned arrangement can guide the movement of the rotating plate 22 through the guide plate 50, so that the rotating plate 22 can rotate smoothly around the axial direction of the positioning sleeve 2. In addition, the cooperation between the guide post 3 and the guide plate 50 can also prevent the rotating plate 22 from tipping over relative to the support platform 1.

[0032] Two baffles 6 are fixed at both ends of the support platform 1. Two baffles 6 are located at each end and spaced apart along the length of the conveyor belt 20. A lever 4 is fixed at both ends of the rotating plate 22. A second guide hole 58 is formed on the surface of each baffle 6. A buffer rod 49 slides through the interior of the second guide hole 58. The buffer rod 49 is horizontally positioned. An abutment plate 48 is fixed to the inner end of the buffer rod 49. The abutment plate 48 abuts vertically against both sides of the lever 4. A third spring 60 is slidably sleeved on the surface of the buffer rod 49, located between the baffles 6 and the abutment plate 48. A fifth limiting plate 59 is fixed to the outer end of the buffer rod 49. When the conveyor belt 20 deviates from its original position, it drives the rotating plate 22 to rotate, causing the actuating rod 4 to push and squeeze the abutment plates 48 on both sides. At the same time, the third spring 60 pushes the actuating rod 4 back to the middle position through the reverse spring, thereby strengthening the rotation plate 22 to return to the correct position, strengthening the correction force of the conveyor belt 20, and reducing the vibration of the actuating rod 4 and the rotating plate 22.

[0033] A second support plate 23 is fixed to the bottom end of the support platform 1. The return conveyor belt in the conveyor belt 20 passes horizontally between the two second support plates 23. A cleaning roller 30 is installed between the two second support plates 23 and at the bottom end of the conveyor belt 20. A left-handed cleaning strip 26 and a right-handed cleaning strip 55 are fixed to both ends of the surface of the cleaning roller 30, respectively. The left-handed cleaning strip 26 and the right-handed cleaning strip 55 clean the coal slag adhering to the bottom surface of the conveyor belt 20. A second rotating shaft 31 is installed at both ends of the cleaning roller 30. The second rotating shaft 31 is rotatably connected to the second support plate 23.

[0034] A second drive gear 24 is sleeved and installed on the outer wall of the second rotating shaft 31. A second rotating rod 29 rotatably passes between the two second support plates 23. A second mounting hole 57 is opened on the surface of the second support plate 23. A second bearing 56 is installed inside the second mounting hole 57, and the second rotating rod 29 passes through the inner cavity of the second bearing 56. A second driven gear 25 is installed on the surface of the second rotating rod 29 and near the inner side of the second support plate 23. The second driven gear 25 is meshed and connected to the second drive gear 24 at the top. A second fan blade 28 and a second cleaning brush 27 are spaced apart on the surface of the second rotating rod 29, and the second cleaning brush 27 contacts the surface of the cleaning roller 30.

[0035] During the movement of the conveyor belt 20, its bottom outer side drives the cleaning roller 30 to rotate, and the cleaning roller 30 cleans the coal slag adhering to the bottom outer side of the conveyor belt 20. During the rotation of the cleaning roller 30, the second driven gear 25 meshes with the second driving gear 24 at the top, driving the second rotating rod 29 to rotate. The second rotating rod 29 drives the second fan blade 28 and the second cleaning brush 27 to rotate. The second fan blade 28 blows air onto the surface of the cleaning roller 30 and the bottom outer side of the conveyor belt 20, dissipating the heat generated by friction, reducing frictional heating of the conveyor belt 20, and drying the damp, muddy coal slag adhering to its surface. This facilitates both the cleaning roller 30's thorough cleaning of the coal slag adhering to the bottom outer side of the conveyor belt 20 and the second cleaning brush 27's brushing and cleaning of the surface of the cleaning roller 30. In this way, the weight of the bottom of the conveyor belt 20 when unloaded is reduced, transmission resistance is decreased, power consumption is saved, and there is no need to install a separate blowing device for cooling and drying the transmission structure.

[0036] This application also relates to a method of using a conveyor belt anti-deviation device. During operation, the rotating plate 22 is rotatably mounted on the top of the support platform 1 via the rotating column 5 and guide column 3. The transmission roller 19 is mounted on the top of the rotating plate 22 via the first support plate 7. The first rotating rod 21 rotates through the two first support plates 7. The first rotating rod 21 is connected to the first driven gear 18 via the meshing of the first driving gear 42. A first fan blade 46 and a first cleaning brush 45 are spaced apart on the surface of the first rotating rod 21. Cam plates 8 are fixed at both ends of the first rotating rod 21. The anti-deviation roller 12 is vertically mounted on both sides of the rotating plate 22 via the uprights 17. The upper half of the anti-deviation roller 12... An upper buffer plate 11 is rotatably mounted on the surface of the anti-deviation roller 12. The upper buffer plate 11 is in buffer contact with the first spring 15 via a connecting rod 13 and a first limiting plate 14. A lower buffer plate 10 is rotatably mounted on the lower half of the surface of the anti-deviation roller 12. The lower buffer plate 10 is in contact with the second spring 34 via a guide rod 38. The guide rod 38 slides through the surface of the actuating plate 9, and the actuating plate 9 is connected to the gasket 67 via a fourth spring 68. A guide post 3 fixed at the bottom of the rotating plate 22 is slidably inserted into the guide plate 50 at the top of the support platform 1. A toggle rod 4 fixed at both ends is set between two baffles 6 and is buffered and abutted by an abutment plate 48 and a third spring 60. Cleaning roller 3 The conveyor belt 20 is positioned below the support platform 1 via a second support plate 23. A right-handed cleaning strip 55 and a left-handed cleaning strip 26 clean the outer bottom edge of the conveyor belt 20, and the belt rotates between the two second support plates 23, passing through a second rotating rod 29. A second fan blade 28 and a second cleaning brush 27 are spaced apart on the surface of the second rotating rod 29. The top end of the conveyor belt 20 slides over the bottom end of the drive roller 19, and its bottom end slides over the top end of the cleaning roller 30, simultaneously driving the drive roller 19 and the cleaning roller 30 to rotate. Through the meshing of the first driving gear 42 and the first driven gear 18, the first rotating rod 21 drives the first fan blade 46 and the first driven gear 27 to rotate. The cleaning brush 45 and cam plate 8 rotate, and the rotating first fan blade 46 blows air to the surface of the transmission roller 19 and the inner side of the conveyor belt 20 to dissipate heat, clean the coal slag, and reduce the heat of the conveyor belt 20 and coal. The rotating first cleaning brush 45 brushes and cleans the surface of the transmission roller 19. Through the meshing of the second driving gear 24 and the second driven gear 25, the second rotating rod 29 drives the second fan blade 28 and the second cleaning brush 27 to rotate. The rotating second fan blade 28 blows air to the surface of the cleaning roller 30 and the outer surface of the conveyor belt 20 to dissipate heat and dry the moisture of the coal slag. The rotating second cleaning brush 27 brushes and cleans the surface of the cleaning roller 30.When the conveyor belt 20 deviates from its designated path, one side becomes higher than the other. The higher side pushes the upper buffer plate 11 upward, while the lower side presses down on the lower buffer plate 10. The upper buffer plate 11, via the first spring 15, abuts against the higher side of the conveyor belt 20, while the lower buffer plate 10, via the second spring 34 and the fourth spring 68, abuts against the lower side of the conveyor belt 20. The rotating first rotating rod 21 drives the cam plate 8 to rotate, intermittently pushing the pressed-down abutting plate 9 upward, thus forcefully correcting and resetting the lower side of the conveyor belt 20. Simultaneously, the rotating plate 22 rotates and tilts due to the conveyor belt 20's deviation, causing the actuating rod 4 to push the abutting plate 48. The third spring 60, the buffer rod 49, and the abutting plate 48 push the actuating rod 4 and the rotating plate 22 back to their original positions, thereby resetting the anti-deviation roller 12 and accelerating the correction of the deviated conveyor belt 20.

[0037] The conveyor belt anti-deviation device of this application has anti-deviation rollers 12 disposed on the left and right sides of the conveyor belt 20, while upper buffer plates 11 and lower buffer plates 10 are disposed on the upper and lower sides of the conveyor belt 20. When the conveyor belt 20 is transporting materials such as coal and does not deviate, its sides do not contact the upper buffer plates 11, lower buffer plates 10, and anti-deviation rollers 12. In addition, when the conveyor belt 20 is not deviating, there is a gap between the bottom end of the actuating plate 9 and the rotating cam 8, and the top end of the rotating cam 8 does not contact the actuating plate 9, thus not affecting the lower buffer plate 10. When the conveyor belt 20 deviates, one side is higher than the other. The higher side pushes the upper buffer plate 11 upward and is cushioned and pressed downward by the upper buffer plate 11 and the first spring 15, reducing the degree of upward deviation; the lower side presses the lower buffer plate 10 downward and is cushioned and bounced upward by the lower buffer plate 10, the second spring 34, and the fourth spring 68, reducing the degree of downward deviation. Simultaneously, the first rotating rod 21 drives the cam plate 8 to rotate and intermittently pushes the jacking plate 9 upward, thereby strengthening the upward thrust of the lower buffer plate 10 on the side of the conveyor belt 20, accelerating the correction and reset of the conveyor belt 20, reducing the degree of deviation of the conveyor belt 20, reducing friction and wear on both sides of the conveyor belt 20, reducing coal spillage, and protecting the safe use of the conveyor belt 20. The intermittent jacking of the conveyor belt 20 by the cam 8 generates a vibration push on the lower edge of the conveyor belt 20, causing materials such as coal at the edge of the conveyor belt 20 to be vibrated and roll into the inward recess of the conveyor belt 20, preventing coal from falling off. Furthermore, the intermittent pushing action of the cam 8 on the conveyor belt 20 can reduce the friction between the outer edge of the conveyor belt 20 and the lower buffer plate 10, thereby reducing the wear on both sides of the conveyor belt 20. In contrast, when the conveyor belt 20 deviates from its course, the prolonged upward pushing action of the lower buffer plate 10 on the lower end of the conveyor belt 20 will cause greater friction and wear between the lower buffer plate 10 and the outer edge of the conveyor belt 20, resulting in wear on the conveyor belt 20 and increased resistance to movement of the conveyor belt 20.

[0038] On both sides of the conveyor belt 20, a second insertion groove 61 and a positioning groove 66 are provided, and the anti-wear edge 33 is detachably snapped in place by the insertion strip 62 and the positioning post 65. Moreover, an anti-tensile strip 63 is provided inside the insertion strip 62 to replace the wear on both sides of the conveyor belt 20, protect the two sides of the conveyor belt 20, and improve the tensile strength of both sides of the conveyor belt 20. Therefore, after the conveyor belt 20 has been used for a long time, if the anti-wear edge 33 on both sides becomes worn, the anti-wear edge 33 can be quickly removed using a sharp hook, flat knife or other structure without stopping the movement of the conveyor belt 20. The new anti-wear edge 33 can then be quickly installed by inserting the insertion strip 62 into the second insertion groove 61, avoiding the impact of stopping the conveyor belt 20 on the coal transportation and effectively reducing the time required for the maintenance of the conveyor belt 20.

[0039] Baffles 6 are provided on both sides of the actuating lever 4, and buffer rods 49, third springs 60, and abutment plates 48 are used to buffer and abut the sides of the actuating lever 4. The rotating plate 22 is rotatably mounted on the top of the support platform 1 via guide posts 3 and rotating posts 5. When the conveyor belt 20 deviates, it drives the rotating plate 22 to rotate left and right, causing the actuating lever 4 to push and squeeze the abutment plates 48 on both sides. At the same time, the third spring 60 pushes the actuating lever 4 back to the middle position through reverse springing, thereby strengthening the rotation plate 22 to return to the correct position, strengthening the correction force of the conveyor belt 20, and reducing the vibration of the actuating lever 4 and the rotating plate 22.

[0040] A first rotating rod 21 is provided at the bottom end of the drive roller 19, and is connected to the first driven gear 18 through a first driving gear 42. A second rotating rod 29 is provided at the bottom end of the cleaning roller 30, and is connected to the second driven gear 25 through a second driving gear 24. Therefore, during the movement of the conveyor belt 20, its inner top side drives the drive roller 19 to rotate, and its outer bottom side drives the cleaning roller 30 to rotate, thereby cleaning the coal slag adhering to the bottom outer side of the conveyor belt 20. At the same time, the first rotating rod 21 drives the first fan blade 46 and the first cleaning brush 45 to rotate. The first fan blade 46 blows air onto the surface of the transmission roller 19 and the inner top of the conveyor belt 20, which can dissipate the heat generated by friction, blow away the adhering dust and coal slag, and cool down the conveyor belt 20. This prevents the conveyor belt 20 from expanding and contracting due to heat, becoming loose or even breaking. It also prevents the heat generated by friction from being conducted to the coal being transported through the conveyor belt 20, which could cause the coal to overheat and spontaneously combust. In addition, the first cleaning brush 45 cleans and scrubs the surface of the transmission roller 19, removing the adhering coal slag.

[0041] Simultaneously, the second rotating rod 29 drives the second fan blade 28 and the second cleaning brush 27 to rotate. The second fan blade 28 blows air onto the surface of the cleaning roller 30 and the outer bottom end of the conveyor belt 20, dissipating the heat generated by friction, reducing frictional heating of the conveyor belt 20, and drying the damp, muddy coal slag adhering to its surface. This facilitates the cleaning roller 30 in thoroughly cleaning the adhering coal slag from the outer bottom end of the conveyor belt 20, and also facilitates the brushing and cleaning of the surface of the cleaning roller 30 by the second cleaning brush 27. In this way, the weight of the bottom end of the conveyor belt 20 when unloaded can be reduced, transmission resistance can be decreased, power consumption can be saved, and there is no need to install a separate blowing device for cooling and drying the transmission structure.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and / or modifications falling within the scope of the invention, and all changes and / or modifications made according to embodiments of the invention should be covered within the protection scope of the invention.
