Description

Technical Field

[0001] This application relates to the field of conveyor belt technology, and in particular to a conveyor belt with an anti-fall structure and a method for preventing it from falling. Background Technology

[0002] Conveyor belts are widely used conveying equipment in industrial automation and logistics. They transport materials from one place to another through continuous or intermittent motion, and can be driven by methods such as electric rollers, friction drives, or chain drives. Conveyor belt systems play a vital role in industries such as packaging, food processing, chemicals, and electronics manufacturing due to their advantages of high efficiency, low energy consumption, and ease of control and maintenance.

[0003] A coal feeder anti-fall conveyor belt, mentioned in an existing Chinese patent (authorization announcement number: CN217534218U), relates to the field of coal conveyor belt technology. It addresses the problem that existing conveyor belts, with their simple structure, are prone to coal falling and slipping on the outer surface of the conveyor belt during conveying at a certain slope. The invention comprises two mounting plates, with multiple conveyor rollers rotatably mounted between the two mounting plates. Each conveyor roller is wrapped with a conveyor belt. Multiple side guards are integrally connected to the symmetrical side surfaces of the conveyor belt. Multiple separating rubber plates are integrally connected to the outer surface of the conveyor belt, with the outer end faces of the separating rubber plates flush with the outer end faces of the side guards. Multiple support legs are fixedly connected to the outer surface of the mounting plates, and adjusting columns are threaded into the threaded holes at the lower ends of the support legs.

[0004] In the aforementioned patent, the side baffles and partitions effectively improve the anti-falling capability of the conveyor belt, preventing coal from falling off the sides of the conveyor belt. However, in actual daily use, when conveying coal, the conveyor belt is usually continuously fed, which may cause the coal on the conveyor belt to accumulate and not be properly spread between each partition. Therefore, during the conveying process with a certain slope, the accumulated coal may still fall off due to gravity. To address this, this application provides a conveyor belt with an anti-falling structure. Summary of the Invention

[0005] The purpose of this application is to address the problem that coal accumulates on the conveyor belt and cannot be properly spread between each partition plate. Therefore, during conveying at a certain slope, the accumulated coal may still fall due to gravity. This application provides a conveyor belt with an anti-fall structure and a method for preventing the coal from falling.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A conveyor belt with an anti-fall structure includes two support frames. Two belt shafts are symmetrically and rotatably connected to opposite faces of the two support frames. A motor is fixedly connected to one side of one of the support frames, and the output end of the motor is fixedly connected to one end of one of the belt shafts. A conveyor belt body is rotatably mounted on the two belt shafts. A support plate is fixedly connected to opposite faces of the two support frames, and the support plate is located inside the conveyor belt body. An anti-fall component is installed on the top of the support plate. The anti-fall component includes two fixed plates symmetrically and fixedly connected to the top of the support plate. A connecting frame is slidably mounted on opposite faces of the two fixed plates. A sliding plate is slidably mounted inside the connecting frame. A connecting shaft is rotatably connected through one side of the sliding plate. A second motor is fixedly connected to one side of one of the support frames, and the output end of the second motor is fixedly connected to one end of the connecting shaft. A gear is fixedly connected to the end of the connecting shaft away from the second motor. A rotating shaft is rotatably connected to the bottom of the two support frames, and a second gear is fixedly connected to one end of the rotating shaft. The second gear meshes with the first gear. A cleaning component is mounted on the rotating shaft.

[0008] By adopting the above technical solution, during the coal feeding process, coal may accumulate on the conveyor belt body. At this time, motor two can be started to drive the connecting shaft to rotate. The rotation of the connecting shaft can drive the anti-drop component to operate simultaneously, so that the anti-drop component can circulate and shake the bottom of the conveyor belt body inside the conveyor belt body, thereby helping to disperse the coal on the conveyor belt and prevent it from accumulating too high in a certain part of the conveyor belt body, thus reducing the risk of coal falling. In addition, when the connecting shaft rotates, it will drive gear one to rotate as well. Since gear one and gear two are meshed with each other, when gear one rotates, it will drive the shaft to rotate continuously through gear two. This rotating shaft will drive the cleaning component at the bottom of the conveyor belt body to operate. The cleaning component can effectively clean the coal slag adhering to the surface of the conveyor belt body, reducing the amount of coal slag adhering to the surface of the conveyor belt body, thereby effectively restoring and improving the friction of the surface of the conveyor belt body, so that the coal can be transported stably and reducing the risk of slippage and falling.

[0009] Furthermore, baffles are symmetrically fixedly connected to both sides of the outer wall of the conveyor belt body, and multiple material support plates are uniformly fixedly connected to the outer wall of the conveyor belt body.

[0010] By adopting the above technical solution, the cooperation between the baffle and the support plate can effectively prevent coal from slipping during the conveying process, and also significantly improve the reliability and efficiency of the conveyor belt itself, keep the coal near the center line of the conveyor belt, reduce coal loss, and increase the stability of coal conveying.

[0011] Furthermore, two guide posts are symmetrically fixedly connected to both sides of the connecting frame, and the other ends of the two guide posts are slidably connected to the fixing plate. A spring is sleeved on each of the two guide posts, one end of the spring is fixedly connected to one side of the connecting frame, and the other end of the spring is fixedly connected to one side of the fixing plate.

[0012] By adopting the above technical solution, after the connecting frame is subjected to a relative force, according to the rebound contraction of the first spring, the connecting frame will move back and forth inside the two fixed plates under the guidance of the two guide columns, thereby driving the sliding plate to move back and forth as well.

[0013] Furthermore, springs are symmetrically fixedly connected to both the upper and lower ends of the sliding plate, and the ends of the springs away from the sliding plate are fixedly connected to the inner wall of the connecting frame. A connecting block is fixedly connected to the top of the sliding plate, and a fitting plate is fixedly connected to the top of the connecting block. Cams are fixedly connected to both ends of the connecting shaft, and the cams can fit against the top surface of the support plate.

[0014] By adopting the above technical solution, the rotating cam can intermittently impact the top of the support plate, thereby causing the sliding plate to vibrate continuously inside the connecting frame due to the rebound and contraction of multiple springs.

[0015] Furthermore, the top of the bonding plate is provided with a groove, and multiple rollers are uniformly rotatably connected in the groove, with the outer walls of the multiple rollers all fitting against the inner wall of the conveyor belt body.

[0016] By adopting the above technical solution, the friction between the inner wall of the conveyor belt body and the bonding plate can be effectively reduced by the bonding of multiple rollers with the inner wall of the conveyor belt body, thereby reducing frictional damage to the surface of the conveyor belt body.

[0017] Furthermore, the cleaning component includes a fixed cylinder fixedly connected to the rotating shaft. Multiple fixed blocks are evenly fixedly connected to the outer wall of the fixed cylinder. Each of the multiple fixed blocks has a T-shaped groove inside. A T-shaped block is slidably arranged inside the T-shaped groove. A brush is fixedly connected to the top of the T-shaped block. The brush is in contact with the bottom surface of the conveyor belt body. A snap-fit ​​component is provided at one end of the T-shaped block.

[0018] By adopting the above technical solution, when the fixed drum rotates, multiple brushes will circulate and wipe the surface of the conveyor belt body, which can effectively clean the coal slag adhering to the surface of the conveyor belt body, reduce the coal slag residue adhering to the surface of the conveyor belt body, enable the coal to be transported stably, and reduce the risk of slippage and falling.

[0019] Furthermore, the snap-fit ​​component includes a groove formed at one end of the T-shaped block, a spring three is fixedly connected in the groove, a buckle is slidably connected in the groove, one end of the spring three is fixedly connected to one end of the buckle, and a slot of the same size as the buckle is formed at the top of one end of the fixing block.

[0020] By adopting the above technical solution, when the brush is severely worn and needs to be replaced, the buckle can be manually pressed and the spring can be squeezed to push the buckle into the T-slot, thereby releasing the engagement between the buckle and the slot. At this time, the T-block can be pulled out of the T-slot to quickly replace the brush.

[0021] A method to prevent falling.

[0022] By adopting the above technical solution, excessive accumulation of coal in a certain part of the conveyor belt body is prevented, thereby reducing the risk of coal falling. By flattening the coal, the friction between the coal and the surface of the conveyor belt body can be increased, reducing the possibility of coal sliding, thereby reducing the risk of coal falling during the conveying process.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. This application includes an anti-drop component. When the motor is started, the connecting shaft rotates. The rotation of the connecting shaft drives the anti-drop component to rotate as well. This allows the anti-drop component to repeatedly vibrate the bottom of the conveyor belt body inside the conveyor belt body, thereby helping to disperse the coal on the conveyor belt and preventing it from accumulating too high in a certain part of the conveyor belt body. This reduces the risk of coal falling off. By flattening the coal, the friction between the coal and the surface of the conveyor belt body can be increased, reducing the possibility of coal slippage and thus reducing the risk of coal falling off during the conveying process.

[0025] 2. This application includes a cleaning component. When the connecting shaft rotates, it drives gear one to rotate as well. Since gear one and gear two mesh with each other, when gear one rotates, it drives the shaft to rotate continuously through gear two. This rotating shaft drives the cleaning component at the bottom of the conveyor belt body to operate. The cleaning component can effectively clean the coal slag adhering to the surface of the conveyor belt body, reducing the amount of coal slag residue adhering to the surface of the conveyor belt body. This effectively restores and improves the friction of the surface of the conveyor belt body, enabling the coal to be transported stably and reducing the risk of slippage and falling.

[0026] 3. This application includes baffles and support plates. Multiple support plates on the conveyor belt body divide the outer wall of the conveyor belt body into multiple areas, allowing coal to remain within each area. The baffles intercept the sides of the conveyor belt body, preventing coal from shifting and falling during transport. Furthermore, in conveying at a certain slope, the cooperation between the baffles and support plates effectively prevents accidental coal slippage during transport, significantly improving the reliability and efficiency of the conveyor belt body, keeping coal near the conveyor belt centerline, reducing coal loss, increasing the stability of coal transport, and preventing coal tumbling or misalignment.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses a conveyor belt with an anti-fall structure and a method for preventing it from falling.

[0036] Reference Figure 1 , Figure 2 and Figure 3A conveyor belt with an anti-fall structure includes two support frames 1. Two belt shafts 2 are symmetrically rotatably connected to the opposite faces of the two support frames 1. A motor 3 is fixedly connected to one side of one of the support frames 1, and the output end of the motor 3 is fixedly connected to one end of one of the belt shafts 2. A conveyor belt body 4 is rotatably mounted on the two belt shafts 2. A support plate 7 is fixedly connected to the opposite faces of the two support frames 1, and the support plate 7 is located inside the conveyor belt body 4. An anti-fall component is installed on the top of the support plate 7. The anti-fall component includes two fixed plates 8 symmetrically fixedly connected to the top of the support plate 7. A connecting frame 9 is slidably mounted on the opposite faces of the two fixed plates 8. An internal sliding plate 12 is provided, and a connecting shaft 14 is rotatably connected through one side of the sliding plate 12. A motor 15 is fixedly connected to one side of one of the support frames 1. The output end of the motor 15 is fixedly connected to one end of the connecting shaft 14. A gear 19 is fixedly connected to the end of the connecting shaft 14 away from the motor 15. A rotating shaft 20 is rotatably connected to the bottom of the two support frames 1. A gear 21 is fixedly connected to one end of the rotating shaft 20. The gear 21 meshes with the gear 19. A cleaning component is installed on the rotating shaft 20. Baffles 5 are symmetrically fixedly connected to both sides of the outer wall of the conveyor belt body 4. Multiple material support plates 6 are evenly fixedly connected to the outer wall of the conveyor belt body 4.

[0037] In operation, firstly, start motor 3 to drive belt shaft 2 to rotate. The mutual rotation of the two belt shafts 2 allows the conveyor belt body 4 to move forward and transport coal normally. Coal can be continuously poured onto the conveyor belt body 4. Multiple support plates 6 on the conveyor belt body 4 divide the outer wall of the conveyor belt body 4 into multiple areas, allowing coal to remain within each area. Baffles 5 intercept the sides of the conveyor belt body 4, preventing coal from shifting and falling during transport. Simultaneously, during transport on a slope, the cooperation of baffles 5 and support plates 6 effectively prevents accidental slippage of coal during transport, significantly improving the reliability and efficiency of the conveyor belt body 4, keeping coal near the centerline of the conveyor belt, reducing coal loss, increasing the stability of coal transport, and preventing coal rolling or misalignment. Additionally, during coal loading, coal may accumulate on the conveyor belt body 4. In this case, start motor 15 to drive connecting shaft 14 to rotate. The rotation of connecting shaft 14 can then... The anti-fall-off component operates simultaneously, causing the bottom of the conveyor belt body 4 to vibrate repeatedly within the conveyor belt body 4. This helps disperse the coal on the conveyor belt, preventing it from accumulating too high in any part of the conveyor belt body 4, thus reducing the risk of coal falling off. By flattening the coal, the friction between the coal and the surface of the conveyor belt body 4 is increased, reducing the possibility of coal slippage and thus reducing the risk of coal falling off during transportation. In addition, when the connecting shaft 14 rotates, it drives gear 19 to rotate as well. Since gear 19 and gear 21 mesh with each other, when gear 19 rotates, it drives the rotating shaft 20 to rotate continuously through gear 21. The rotating shaft 20 then drives the cleaning component at the bottom of the conveyor belt body 4 to operate. The cleaning component can effectively clean the coal slag adhering to the surface of the conveyor belt body 4, reducing the amount of coal slag residue adhering to the surface of the conveyor belt body 4. This effectively restores and improves the friction of the surface of the conveyor belt body 4, allowing coal to be transported stably and reducing the risk of slippage and falling off.

[0038] Reference Figure 1 , Figure 2 and Figure 3Two guide posts 10 are symmetrically fixedly connected to both sides of the connecting frame 9. The other ends of the two guide posts 10 are slidably connected to the fixed plate 8. A spring 11 is sleeved on each of the two guide posts 10. One end of the spring 11 is fixedly connected to one side of the connecting frame 9, and the other end of the spring 11 is fixedly connected to one side of the fixed plate 8. A spring 2 13 is symmetrically fixedly connected to both the upper and lower ends of the sliding plate 12. The ends of the spring 2 13 away from the sliding plate 12 are fixedly connected to the inner wall of the connecting frame 9. A connecting block 16 is fixedly connected to the top of the sliding plate 12. A bonding plate 17 is fixedly connected to the top of the connecting block 16. Cams 30 are fixedly connected to both ends of the connecting shaft 14. The cams 30 can fit against the top surface of the support plate 7. A groove is opened on the top of the bonding plate 17. Multiple rollers 18 are evenly rotatably connected in the groove. The outer walls of the multiple rollers 18 are all fitted against the inner wall of the conveyor belt body 4.

[0039] In use, motor 15 is first started to drive the connecting shaft 14 to rotate, thereby causing the cams 30 at both ends of the connecting shaft 14 to rotate continuously. The rotating cams 30 intermittently impact the top of the support plate 7. According to the rebound contraction of multiple springs 13, the sliding plate 12 can be driven to vibrate continuously inside the connecting frame 9. When the sliding plate 12 vibrates, it will transmit some force to the connecting frame 9. After the connecting frame 9 is subjected to the relative force, according to the rebound contraction of spring 11, the connecting frame 9 will move back and forth inside the two fixed plates 8 under the guidance of the two guide posts 10. This will drive the sliding plate 12 to move back and forth as well. Through the cooperation of the sliding plate 12 and the connecting frame 9, The adhesive plate 17 can effectively drive the bonding plate 17 to reciprocate inside the conveyor belt body 4. The continuous shaking of the bottom surface of the conveyor belt body 4 by the adhesive plate 17 helps to disperse the coal on the conveyor belt, preventing it from accumulating too high in a certain part of the conveyor belt body 4, thereby reducing the risk of coal falling. By flattening the coal, the friction between the coal and the surface of the conveyor belt body 4 can be increased, reducing the possibility of coal sliding, thereby reducing the risk of coal falling during the conveying process. At the same time, the adhesion of multiple rollers 18 to the inner wall of the conveyor belt body 4 can effectively reduce the friction between the inner wall of the conveyor belt body 4 and the adhesive plate 17, thereby reducing friction damage to the surface of the conveyor belt body 4 and effectively improving the service life of the conveyor belt body 4.

[0040] Reference Figure 1 , Figure 4 and Figure 5The cleaning component includes a fixed cylinder 22 fixedly connected to the rotating shaft 20. Multiple fixed blocks 23 are evenly fixedly connected to the outer wall of the fixed cylinder 22. Each of the multiple fixed blocks 23 has a T-shaped groove 24 inside. A T-shaped block 25 is slidably arranged inside the T-shaped groove 24. A brush 26 is fixedly connected to the top of the T-shaped block 25. The brush 26 is in contact with the bottom surface of the conveyor belt body 4. A snap-fit ​​is provided at one end of the T-shaped block 25. The snap-fit ​​includes a groove opened at one end of the T-shaped block 25. A spring 27 is fixedly connected in the groove. A buckle 28 is slidably connected in the groove. One end of the spring 27 is fixedly connected to one end of the buckle 28. A slot 29 of the same size as the buckle 28 is opened at the top of one end of the fixed block 23.

[0041] During use, because gear 19 and gear 21 mesh with each other, when gear 19 rotates, it drives the shaft 20 to rotate continuously via gear 21. This rotation of the shaft 20, in turn, drives the fixed cylinder 22 to rotate. As the fixed cylinder 22 rotates, multiple brushes 26 cyclically wipe and clean the surface of the conveyor belt body 4. This effectively removes coal slag adhering to the surface of the conveyor belt body 4, reducing coal slag residue and restoring and improving the friction of the conveyor belt body 4 surface. This allows for stable coal transport and reduces slippage and spillage. To mitigate the risk of damage, when the brush 26 is severely worn and needs replacement, the buckle 28 can be manually pressed and the spring 3 27 compressed to push the buckle 28 into the T-slot 24, thereby releasing the engagement with the slot 29. At this time, the T-block 25 can be pulled out of the T-slot 24 for quick replacement of the brush 26. Then, the new T-block 25 and brush 26 are inserted into the T-slot 24. At this time, according to the rebound of the spring 3 27, the buckle 28 will be pushed into the slot 29. The slot 29 limits the position of the buckle 28, so that the T-block 25 can be stably placed inside the T-slot 24, preventing the T-block 25 from falling off.

[0042] The implementation principle of this embodiment of a conveyor belt with an anti-drop structure and its anti-drop method is as follows: In use, the motor 3 is first started to drive the belt shaft 2 to rotate. Through the mutual rotation of the two belt shafts 2, the conveyor belt body 4 can move forward normally to transport coal. At this time, coal can be continuously poured onto the conveyor belt body 4. Multiple material support plates 6 installed on the conveyor belt body 4 can divide the outer wall of the conveyor belt body 4 into multiple areas, allowing the coal to remain within each area. The baffles 5 can intercept the coal on both sides of the conveyor belt body 4, thereby preventing the coal from moving to the sides during transportation and causing it to fall. In addition, during the conveying process with a certain slope, the cooperation between the baffle 5 and the support plate 6 can effectively prevent coal from accidentally slipping during the conveying process, and also significantly improve the reliability and efficiency of the conveyor belt body 4, keep the coal near the center line of the conveyor belt, reduce coal loss, increase the stability of coal conveying, and prevent coal from rolling or misaligning. In addition, during the coal feeding process, coal may accumulate on the conveyor belt body 4. At this time, the motor 15 can be started to drive the connecting shaft 14 to rotate, so that the cams 30 at both ends of the connecting shaft 14 rotate continuously. Through the rotation of the cams 30, the top of the support plate 7 can be intermittently moved. The impact causes the sliding plate 12 to vibrate continuously within the connecting frame 9 due to the rebound and contraction of multiple springs 13. As the sliding plate 12 vibrates, it transmits a portion of the force to the connecting frame 9. Upon receiving this force, the connecting frame 9, guided by the two guide posts 10, reciprocates left and right within the two fixed plates 8, causing the sliding plate 12 to reciprocate as well. Through the cooperation of the sliding plate 12 and the connecting frame 9, the bonding plate 17 is effectively driven to reciprocate within the conveyor belt body 4. The continuous shaking of the bottom surface inside the conveyor belt body 4 by 17 helps to disperse the coal on the conveyor belt and prevent it from accumulating too high in a certain part of the conveyor belt body 4, thereby reducing the risk of coal falling. By flattening the coal, the friction between the coal and the surface of the conveyor belt body 4 can be increased, reducing the possibility of coal sliding, thereby reducing the risk of coal falling during the conveying process. At the same time, the contact between the multiple rollers 18 and the inner wall of the conveyor belt body 4 can effectively reduce the friction between the inner wall of the conveyor belt body 4 and the contact plate 17, thereby reducing friction damage to the surface of the conveyor belt body 4 and effectively improving the service life of the conveyor belt body 4.Additionally, as the connecting shaft 14 rotates, it drives gear 19 to rotate as well. Since gear 19 meshes with gear 21, the rotation of gear 19 drives the rotating shaft 20 to rotate continuously via gear 21. This rotating shaft 20 then drives the fixed cylinder 22 to rotate as well. As the fixed cylinder 22 rotates, multiple brushes 26 cyclically wipe and clean the surface of the conveyor belt body 4, effectively removing coal slag adhering to the surface and reducing coal slag residue. This effectively restores and improves the friction of the conveyor belt body 4 surface, allowing coal to be transported stably. To minimize the risk of slippage and drop, when the brush 26 is severely worn and needs replacement, the buckle 28 can be manually pressed and the spring 3 27 compressed to push the buckle 28 into the T-slot 24, thus releasing the engagement with the slot 29. At this point, the T-block 25 can be pulled out of the T-slot 24 for quick replacement of the brush 26. The new T-block 25 and brush 26 are then inserted into the T-slot 24. The spring 3 27's rebound will push the buckle 28 into the slot 29, which then limits the position of the buckle 28, ensuring the T-block 25 remains stable within the T-slot 24 and preventing it from falling off.

S2: During the coal feeding process, coal may accumulate on the conveyor belt body (4). At this time, start the motor (15) to drive the connecting shaft (14) to rotate. The rotation of the connecting shaft (14) will drive the anti-drop component to operate together, so that the anti-drop component will repeatedly shake the bottom of the conveyor belt body (4) inside the conveyor belt body (4) to help disperse the coal on the conveyor belt and prevent it from accumulating too high in a certain part of the conveyor belt body (4), thereby reducing the risk of coal falling. By flattening the coal, the friction between the coal and the surface of the conveyor belt body (4) is increased, reducing the possibility of coal sliding, thereby reducing the risk of coal falling during the conveying process. S3: In addition, while the connecting shaft (14) rotates, it will drive the gear (19) to rotate as well. In this way, the rotating shaft (20) will drive the cleaning component at the bottom of the conveyor belt body (4) to operate. The cleaning component effectively cleans the coal slag adhering to the surface of the conveyor belt body (4), reducing the coal slag residue adhering to the surface of the conveyor belt body (4). This effectively restores and improves the friction of the surface of the conveyor belt body (4), so that the coal can be transported stably and the risk of slipping and falling is reduced. S4: When the brush (26) is severely worn and needs to be replaced, manually press the buckle (28) and squeeze the spring three (27) to retract, so as to push the buckle (28) into the T-slot (24) to release the engagement with the slot (29). At this time, pull the T-block (25) to pull it out of the T-slot (24) to quickly replace the brush (26) and improve cleaning efficiency.
