Abstract
Description
Technical Field
[0001] This utility model relates to the field of mineral conveying technology, and in particular to a lightweight, high-strength mining belt conveyor roller. Background Technology
[0002] In the process of mining operations, belt conveyors play a vital role. They are one of the key pieces of equipment for material transportation. As the core component of the belt conveyor, the rollers have an extremely important impact on the performance and service life of the entire machine. These rollers not only need to bear heavy loads of materials, but also need to ensure the smooth operation of the conveyor belt. Therefore, their design and manufacturing quality are directly related to the efficiency and reliability of the entire conveying system.
[0003] In practice, traditional belt conveyors operate in harsh environments, and some mineral debris enters the conveyor during mineral transport. Since this debris cannot be effectively removed during operation, it accumulates between the conveyor belt and the rollers. This debris is then squeezed between the rollers and the conveyor belt. Because mineral debris is hard and sharp, it easily scratches or wears the surfaces of the conveyor belt and rollers. Over time, this accumulation leads to belt damage and decreased roller performance, ultimately affecting the overall operating efficiency and stability of the conveyor and causing irreversible damage to the conveyor components. Summary of the Invention
[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that mineral debris is not easy to clean and can easily cause friction damage to the conveyor. To this end, we propose a lightweight and high-strength mining belt conveyor roller.
[0005] To achieve the above objectives, this application adopts the following technical solution: a lightweight, high-strength mining belt conveyor roller, comprising a housing, the key technical point of which is that a drive motor is fixedly connected to one side of the housing, the output shaft of the drive motor is fixedly connected to a first transmission rod disposed at one end inside the housing, the first transmission rod is sleeved over a first roller body, a second transmission rod is disposed on the other side of the housing opposite to the first roller body, the second transmission rod is sleeved over a second roller body, a conveyor belt is installed on the surface of the first roller body and the second roller body, the first transmission rod and the second transmission rod are connected by belt drive, gears are fixedly connected to both ends of the first transmission rod and the second transmission rod, a first long rod with first transmission teeth connected at both ends is disposed on one side of the first transmission rod, a second long rod with second transmission teeth connected at both ends is disposed on one side of the second transmission rod, the gear on the first transmission rod meshes with the first transmission teeth at corresponding positions on the first transmission rod, the gear on the second transmission rod meshes with the second transmission teeth at corresponding positions on the second transmission rod, a first spiral brush is fixedly connected to the surface of the first long rod, and a second spiral brush is fixedly connected to the surface of the second long rod.

[0007] Preferably, a plurality of springs are fixedly connected to the top of the rotating plate, and a long plate is fixedly connected to the top of the springs, the long plate being fixedly connected to the inner surface of the housing.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0018] Reference Figure 1 - Figure 4As shown, this embodiment provides a lightweight, high-strength mining belt conveyor roller, including a housing 1. A drive motor 2 is fixedly connected to one side of the housing 1. A first transmission rod 3 and a second transmission rod are rotatably connected to both ends inside the housing 1. The output end of the drive motor 2 is fixedly connected to the first transmission rod 3. A first roller body 4 is fixedly connected to the surface of the first transmission rod 3. A conveyor belt 5 is installed on the surface of the first roller body 4. The two first transmission rods 3 and the second transmission rod are connected by the conveyor belt 5. In this embodiment, gears 6 are fixedly connected to both sides of the first transmission rod 3 and both sides of the second transmission rod. First transmission teeth 7 and second transmission teeth are rotatably connected to both sides inside the housing 1. The first transmission teeth 7 are fixedly connected to both ends of the first long rod 8 and mesh with the gears 6 on the first transmission rod 3. A first spiral brush 9 is fixedly connected to the surface of the first long rod 8. The second transmission teeth are fixedly connected to both ends of the second long rod, and a second spiral brush is fixedly connected to the surface of the second long rod. When the operator starts the drive motor 2, the first transmission rod 3 rotates, which in turn drives the first roller body 4 to run the conveyor belt 5. The rotation of the first transmission rod 3 then drives the gears 6 to rotate, which in turn drives the first transmission teeth 7 to rotate the first long rod 8. The rotation of the first long rod 8 drives the first spiral brush 9 to rotate on one side of the first roller body 4. The process of the second long rod driving the second spiral brush in this embodiment is the same and will not be described further. The meshing connection between gear 6 and the first transmission gear 7 causes the first spiral brush 9 to rotate in the opposite direction to the first roller body 4 and the conveyor belt 5. The surface of the first spiral brush 9 adheres to the surface of the first roller body 4 and the interior of the conveyor belt 5. As the conveyor belt 5 rotates in the opposite direction, it brushes the inner wall of the conveyor belt 5 and the surface of the first roller body 4. The spiral arrangement of the first spiral brush 9 also allows it to sweep away debris that falls onto the inner wall of the conveyor belt 5 from the surface of the first roller body 4. The spiral brush 9 can gradually move to one side as it rotates, thus effectively cleaning both the first roller body 4 and the inner wall of the conveyor belt 5. The surface of the main body 4 is cleaned, and dirt and debris falling into the conveyor belt 5 are guided to be discharged from the inner diameter of the conveyor belt 5. This prevents the first roller body 4 and the conveyor belt 5 from rotating with debris, effectively reducing the wear caused by debris on the first roller body 4 and the conveyor belt 5 during ore production, reducing equipment failures caused by debris accumulation, and thus ensuring the stable operation of the device and improving its production efficiency. In addition, the first roller body 4 is made of high-strength alloy steel and has a hollow shaft design inside. It is lightweight, high-strength, and corrosion-resistant, making it suitable for various harsh mining environments and providing a strong guarantee for the safe production of mining enterprises.
[0019] Reference Figure 2 - Figure 4As shown in this embodiment: two shafts 10 are fixedly connected inside the housing 1, and each shaft 10 is connected to a rotating plate 11. The two shafts in this embodiment have the same structure and principle. The structure and principle of one shaft are explained below: one end of the rotating plate 11 abuts against the surface of the first spiral brush 9. The rotating plate 11 rotates about the shaft 10 as an axis. By installing it on one side of the first spiral brush 9, one end of the rotating plate 11 abuts against the top of the first spiral brush 9. When the first spiral brush 9 rotates, the rotating plate 11 contacts the surface of the first spiral brush 9 and generates friction, so that friction is generated between the first spiral brush 9 and the rotating plate 11. The rotating plate 11 pushes the dust adsorbed on the surface of the first spiral brush 9 to the side of the first spiral brush 9 away from the roller body 4, thereby maintaining the cleanliness of the surface of the first spiral brush 9 and ensuring the cleaning effect of the first spiral brush 9 on the first roller body 4 and the conveyor belt 5.
[0020] Reference Figure 2 and Figure 3 As shown in this embodiment: several springs 12 are fixedly connected to the top of the rotating plate 11, and a long plate 13 is fixedly connected to the top of the springs 12. The two ends of the long plate 13 are fixedly connected to the inner wall of the housing 1. The springs 12 are positioned between the rotating plate 11 and the long plate 13, so that the rotating plate 11 and the long plate 13 maintain a constant distance. When the spiral brush 9 rotates, it will push the rotating plate 11 to rotate a certain distance. The springs 12 limit the distance that the first spiral brush 9 drives the rotating plate 11 to rotate, so that the rotation of the rotating plate 11 will drive the springs 12 to store force, and then push the rotating plate 11 to reset, thereby knocking the surface of the first spiral brush 9, effectively removing the dirt adsorbed on the surface of the first spiral brush 9, improving the cleaning effect of the rotating plate 11 on the first spiral brush 9, and further ensuring the effective operation of the spiral brush 9.
[0021] Reference Figure 2 and Figure 3 As shown in this embodiment: several support rods 14 are fixedly connected inside the housing 1. A sleeve 15 is rotatably connected to the surface of the support rods 14. The surface of the sleeve 15 abuts against the inner wall of the conveyor belt 5. When the conveyor belt 5 is running, the bottom of its load-bearing point is supported by the support rods 14 and the sleeve 15. The rotation of the sleeve 15 and the surface of the support rods 14 reduces the friction between the conveyor belt 5 and the sleeve 15, thereby supporting the conveyor belt 5 and preventing the load-bearing surface of the conveyor belt 5 from sagging and loosening due to long-term operation. This further improves the load-bearing capacity of the conveyor belt 5 to be suitable for higher intensity operating loads.
[0022] Reference Figure 1As shown in this embodiment: one end of the bottom of the housing 1 is fixedly connected to an inclined plate 16, and a collection box 17 is provided at the bottom of the two inclined plates 16. When the first spiral brush 9 sweeps the debris on the conveyor belt 5 and the first roller body 4 and guides the debris to one side, by setting the inclined plate 16 at the bottom of the housing 1 and placing it on the side where the debris is discharged from the conveyor belt 5, when the debris falls, the inclined plate 16 guides the falling debris, so that the debris enters the collection box 17 through the inclined plate 16 for centralized collection, thereby preventing the cleaned debris from splashing and polluting the surrounding environment, so that the staff can centrally process the cleaned debris.
[0023] Reference Figure 1 and Figure 3 As shown in this embodiment: sleeve plates 18 are fixedly connected to both sides of the housing 1. The inner diameter of the sleeve plates 18 is slightly larger than the surface size of the conveyor belt 5. By sleeve plates 18 being fitted onto both sides of the conveyor belt 5, the gap between the conveyor belt 5 and the top of the housing 1 is shielded and protected, thereby reducing the possibility of debris entering the interior of the conveyor belt 5 through the gap between the housing 1 and the conveyor belt 5, preventing debris from interfering with or damaging the running parts inside the conveyor belt 5, and improving the overall stability and durability of the equipment. At the same time, the material of the sleeve plates 18 is preferably a wear-resistant and corrosion-resistant material to ensure that it can maintain a good protective effect in the harsh mining environment.
[0024] This embodiment uses the first transmission rod as an example to illustrate the working principle: The operator starts the drive motor 2, which drives the first transmission rod 3 to rotate, thus driving the first roller body 4 to run the conveyor belt 5. This causes the second roller body and the second transmission rod to rotate sequentially. The rotation of the first transmission rod 3 then drives the gear 6 to rotate, which in turn drives the first transmission gear 7 to rotate the first long rod 8. The rotation of the first long rod 8 drives the first spiral brush 9 to rotate on one side of the first roller body 4. Through the meshing connection between the gear 6 and the first transmission gear 7, the first spiral brush 9 rotates in the opposite direction to the first roller body 4 and the conveyor belt 5. The surface of the first spiral brush 9 adheres to the surface of the first roller body 4 and the interior of the conveyor belt 5. During the operation of the conveyor belt 5, it interacts with... Its reverse rotation further scrubs the inner wall of the conveyor belt 5 and the surface of the first roller body 4. The spiral arrangement of the first spiral brush 9 cleans the debris that falls onto the inner wall of the conveyor belt 5 from the surface of the first roller body 4. The spiral brush 9 gradually moves to one side as it rotates, cleaning the surface of the first roller body 4 while simultaneously guiding the dirt and debris that falls into the conveyor belt 5, allowing it to exit from the inner diameter of the conveyor belt 5. A rotating plate 11 rotates along the shaft 10. Installed on one side of the first spiral brush 9, one end of the rotating plate 11 abuts against the top of the first spiral brush 9. As the first spiral brush 9 rotates, the rotating plate 11 and the first spiral brush 9... Friction is generated on the surface of the brush 9, causing friction between the first spiral brush 9 and the rotating plate 11. The rotating plate 11 pushes the dust adsorbed on the surface of the first spiral brush 9 away from the first roller body 4. A spring 12 is placed between the rotating plate 11 and the long plate 13 to maintain a constant distance between them. When the first spiral brush 9 rotates, it will push the rotating plate 11 to rotate a certain distance. The spring 12 limits the distance that the first spiral brush 9 drives the rotating plate 11 to rotate. The rotation of the rotating plate 11 will cause the spring 12 to store force, and then push the rotating plate 11 to return to its original position, thus striking the surface of the first spiral brush 9. When the conveyor belt 5 runs, the bottom of its bearing point is supported by the support rod 1. The support of sleeve 15 and the rotation of sleeve 15 reduce the friction between the conveyor belt 5 and sleeve 15, thereby supporting the conveyor belt 5 and preventing the load-bearing surface of the conveyor belt 5 from sagging and loosening due to long-term operation. When the first spiral brush 9 sweeps the debris on the conveyor belt 5 and the first roller body 4 and guides the debris to one side, the inclined plate 16 is set at the bottom of the housing 1 and placed on the side where the debris is discharged from the conveyor belt 5. When the debris falls, the inclined plate 16 guides the falling debris into the collection box 17 for centralized collection. The sleeve 18 is set on both sides of the conveyor belt 5 to cover and protect the gap between the conveyor belt 5 and the top of the housing 1.This reduces the possibility of debris entering the conveyor belt 5 through the gap between the housing 1 and the conveyor belt 5.
