Description

Technical Field

[0001] This utility model belongs to the field of mining conveyor belt technology, and in particular relates to a mining conveyor belt idler that is easy to replace. Background Technology

[0002] Mining trough conveyor belts are a type of conveyor belt widely used in the mining industry. They are typically composed of a base belt, a cover layer, and side rubber. The trough design is formed by multiple idler groups supporting the trough cross section. Generally, three idlers are used, with the middle idler horizontal and the two side idlers inclined, so that the conveyor belt forms a trough shape. This can effectively increase the loading capacity of materials and prevent materials from scattering, thereby improving conveying efficiency and stability.

[0003] Currently, most minerals are transported using mining trough conveyor belts. The idlers of these belts are mostly fixed with bolts. When an idler is damaged, the user needs to replace it. The bolts are difficult to install and remove, and replacing multiple idlers in the same group takes even more time. Therefore, there is a need for a mining conveyor belt idler that is easy to replace. This idler can be fixed with a clip-on structure, which avoids the time required for replacement and increases the speed of replacement. Utility Model Content

[0004] The purpose of this invention is to provide a mine conveyor belt idler that is easy to replace. It has a locking structure that can fix the idler of the mine conveyor belt, which avoids the time required for users to replace it and improves the speed of replacing the mine conveyor belt idler, thereby solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A mine conveyor belt idler that is easy to replace includes multiple identical fixing frames fixed to the top of the conveyor belt frame. A housing is provided on the top of each fixing frame. Three idler roller groups are fixedly connected to the top of the housing by bolts. Two symmetrical slots are fixedly connected to the bottom of the housing. A mounting frame is fixedly connected to the inner cavity of each fixing frame. A bidirectional threaded rod is rotatably connected to the inner cavity of each fixing frame. The bidirectional threaded rod passes through the mounting frame and is rotatably connected to it. A bevel gear is fixedly connected to the surface of the bidirectional threaded rod. A rotating rod is provided through the top of the fixed frame. The top of the rotating rod passes through the inner cavity of the mounting frame and is fixedly connected to a second bevel gear. The first bevel gear and the second bevel gear are threaded together. The bottom of the rotating rod passes through the outside of the fixed frame and is fixedly connected to a rotating disk. The inner cavity of the fixed frame is provided with two symmetrical sliding plates. A bidirectional threaded rod passes through the sliding plates and is threadedly connected to the sliding plates. The top of the fixed frame has four symmetrical sliding grooves. The top of the sliding plates passes through the sliding grooves and is fixedly connected to a locking plate. The locking plate is adapted to the locking groove. The top of the fixed frame is fixedly connected to two symmetrical limiting plates.

[0006] Preferably, the fixing frame is adapted to the housing, and the front and back sides of the inner cavity of the housing are respectively attached to the front and back sides of the fixing frame.

[0007] Preferably, the bottom of the casing is fixedly connected with multiple longitudinal reinforcing plates, and the cross-section of the casing is inverted U-shaped.

[0008] Preferably, the mounting bracket has an H-shaped cross-section, and the top of the sliding plate fits against the top of the inner cavity of the fixing bracket.

[0024] Example 2:

[0025] Figure 1-4This invention illustrates an easily replaceable mining conveyor belt idler according to an embodiment of the present invention. It includes multiple identical fixing frames 2 fixed to the top of the conveyor belt frame 1. A housing 3 is provided on the top of the fixing frame 2, and three idler roller groups 4 are fixedly connected to the top of the housing 3 by bolts. Two symmetrical slots 5 are fixedly connected to the bottom of the housing 3. A mounting frame 6 is fixedly connected to the inner cavity of the fixing frame 2. A bidirectional threaded rod 7 is rotatably connected to the inner cavity of the fixing frame 2, passing through the mounting frame 6 and rotatably connected to it. A bevel gear 8 is fixedly connected to the surface of the bidirectional threaded rod 7. A rotating rod 9 is provided through the top of the fixing frame 2, and the top of the rotating rod 9 passes through the inner cavity of the mounting frame 6 and is fixedly connected to a bevel gear 10. The first bevel gear 8 and the second bevel gear 10 are threaded together. The bottom of the rotating rod 9 extends through to the outside of the fixed frame 2 and is fixedly connected to the rotating disk 11. The inner cavity of the fixed frame 2 is provided with two symmetrical sliding plates 12. The bidirectional threaded rod 7 passes through the sliding plate 12 and is threadedly connected to the sliding plate 12. The top of the fixed frame 2 is provided with four symmetrical sliding grooves 13. The top of the sliding plate 12 passes through the sliding groove 13 and is fixedly connected to the clamping plate 14. The bottom of the clamping plate 14 fits against the top of the fixed frame 2.

The limiting plates 15 are located on both sides of the clamping groove 5 and fit against the reinforcing plate at the bottom of the casing 3.

[0026] Working principle: When using this utility model, the user places the housing 3 on top of the fixed frame 2, so that the limiting plate 15 limits the housing 3. Rotating the rotating disk 11 causes the rotating rod 9 to drive the bidirectional threaded rod 7 to rotate through the bevel gear 10 and bevel gear 8. This causes the bidirectional threaded rod 7 to move threadedly with the sliding plate 12. Through the limiting of the sliding groove 13, the two symmetrical sliding plates 12 drive the two symmetrical clamping plates 14 to move away from each other, so that the clamping plates 14 enter the inner cavity of the limiting plate 15, completing the installation of the idler roller group 4. This avoids the user having to spend a lot of time when replacing it, and improves the speed of replacing the idler rollers of the mining conveyor belt. With the setting of the bottom reinforcement plate of the housing 3, when the idler roller group 4 is transporting minerals on the conveyor belt, the reinforcement plate at the bottom of the housing 3 will support the housing 3, preventing the housing 3 from bending when the idler roller group 4 is under pressure, thus improving the stability of the housing 3.

[0027] In summary, this easily replaceable mining conveyor belt idler utilizes a locking mechanism. By placing the housing 3 on top of the fixing frame 2 and rotating the rotating disk 11, the rotating rod 9 drives the bidirectional threaded rod 7 to rotate via the bevel gear 10 and bevel gear 8. Through the limiting of the sliding groove 13, the two symmetrical sliding plates 12 drive the two symmetrical clamping plates 14 to move away from each other, allowing the clamping plates 14 to enter the inner cavity of the clamping groove 5. This achieves the goal of fixing the mining conveyor belt idler through the clamping structure, avoiding the time-consuming replacement process and improving the speed of replacing the mining conveyor belt idler.
