[0002] Belt conveyors are widely used in metallurgy, mining, grain, steel, food processing, cement, water conservancy, and ports as material transport equipment. In the structure of a belt conveyor, idlers play a crucial role in supporting the conveyor belt and the weight of the materials; they are the most frequently used and replaced components.
[0003] Chinese utility model patent with announcement number CN219362303U discloses a high-sealing conveyor belt idler. Through a specific structural design, the idler has achieved good performance in terms of waterproof and dustproof effects, and to a certain extent meets the usage requirements of some working conditions. However, in practical application and maintenance, the aforementioned high-sealing conveyor belt idlers still have some defects that need improvement. Specifically, the first pressure cap of the idler is threadedly connected to the second pressure cap and the bearing housing, and lacks an effective locking structure. This leads to the threaded connections between the first and second pressure caps, and between the first pressure cap and the bearing housing, easily loosening during long-term operation due to continuous vibration. In severe cases, this can even cause the pressure caps to fall off, affecting not only the normal operation of the idler but also potentially causing equipment failure and safety hazards. Therefore, it is necessary to develop a roller to address the aforementioned shortcomings. Utility Model Content

[0021] In one specific embodiment of this utility model, a high-sealing conveyor belt idler is included. Specifically, it adopts a high-sealing conveyor belt idler disclosed in Chinese Utility Model Patent Publication No. CN219362303U, which belongs to the prior art and will not be described in detail here. This application also includes: The first limiting component is fixed to one end of the bearing housing 100 of the high-seal conveyor belt idler; The second limiting component is movably provided at one end of the first cover 200 and the second cover 300 of the high-sealing conveyor belt idler; The third limiting component can be detachably connected between the first limiting component and the second limiting component on the first pressure cover 200, and between the second limiting component on the first pressure cover 200 and the second limiting component on the second pressure cover 300.
[0022] In a specific embodiment of this utility model, the second limiting component includes an arc-shaped block 400, a prism 500, a first insertion part 600, and an orientation mechanism. The prism 500 is fixedly connected between the arc-shaped block 400 and the first insertion part 600. First annular grooves 700 are respectively formed on the end faces of the first pressure cap 200 and the second pressure cap 300. The prism 500 is movably connected to the side wall of the first annular groove 700. Specifically, the cross-section of the prism 500 is a regular polygon, and its maximum diagonal dimension is smaller than the width of the first annular groove 700, ensuring that the prism 500 can rotate and revolve within the first annular groove 700. A second annular groove 800 is formed on the side wall of the first annular groove 700, and the end of the arc-shaped block 400 is located in the second annular groove 800.

[0023] In a specific embodiment of this utility model, the orientation mechanism includes a connecting block 900 and an orientation block 1000. A prism 500 passes through the connecting block 900, and a first elastic retaining ring 510 is engaged on the prism 500 or between the prism 500 and the first insertion part 600. The first elastic retaining ring 510 contacts the end of the connecting block 900 away from the arc-shaped block 400. One end of the orientation block 1000 is fixedly connected to the connecting block 900, and the other end of the orientation block 1000 is slidably connected to the first annular groove 700. Specifically, the orientation block 1000 can be a cylindrical structure or other structures, and it is clearance-fitted with the side wall of the first annular groove 700 to ensure that it can move within the first annular groove 700. Through the arrangement of the connecting block 900 and the orientation block 1000, it is ensured that the prism 500 and the arc-shaped block 400 will not rotate, and the arc-shaped block 400 is prevented from coming out of the first annular groove 700.
[0024] In a specific embodiment of this utility model, the first limiting component includes a second insertion part 1100 fixedly connected to the bearing seat 100; a third limiting component can be detachably connected between the second insertion part 1100 and the first insertion part 600 on the first pressure cover 200, and between the first insertion part 600 on the first pressure cover 200 and the first insertion part 600 on the second pressure cover 300; an anti-detachment structure for preventing the third limiting component from detaching is provided on the first insertion part 600 or the second insertion part 1100.
[0025] In a specific embodiment of this utility model, the third limiting component includes a third insertion portion 1200, and a first insertion portion 600 and a second insertion portion 1100 are respectively inserted into the ends of the third insertion portion 1200. Specifically, the first insertion portion 600 and the second insertion portion 1100 can be cylindrical structures with the same diameter; the third insertion portion 1200 can be a plate structure, with through holes at both ends matching the diameter of the cylindrical structure.
[0026] In a specific embodiment of this utility model, the anti-detachment structure includes a second elastic retaining ring 610, which is snapped onto the first insertion part 600 corresponding to the first pressure cover 200. The second elastic retaining ring 610 is located on the side of the outer third insertion part 1200 away from the arc-shaped block 400.
[0027] In a specific embodiment of this utility model, the third insertion portion 1200 between the first insertion portion 600 on the first pressure cover 200 and the first insertion portion 600 on the second pressure cover 300 is located on the outer side.
[0028] Install the second limiting component: For the first pressure cap 200 and the second pressure cap 300, place the arc-shaped block 400 into the first annular groove 700 on its end face, so that the arc-shaped block 400 contacts the bottom wall of the first annular groove 700. Rotate the arc-shaped block 400 by the prism 500 or the first insertion part 600, so that the end of the arc-shaped block 400 enters the second annular groove 800 on the side wall of the first annular groove 700. Fit the connecting block 900 of the orientation mechanism onto the end of the prism 500 that protrudes from the first annular groove 700, and insert the orientation block 1000 into the first annular groove 700. Engage the first elastic retaining ring 510 on the prism 500 or between the prism 500 and the first insertion part 600, so that the first elastic retaining ring 510 contacts the end of the connecting block 900 away from the arc-shaped block 400.
[0029] Install the third limiting component: Move the second limiting component on the first pressure cover 200 to a suitable position along the corresponding first annular groove 700, and insert both ends of one third insertion part 1200 into the second insertion part 1100 and the first insertion part 600 on the first pressure cover 200, respectively. Then move the second limiting component on the second pressure cover 300 to a suitable position along the corresponding first annular groove 700, and insert both ends of another third insertion part 1200 into the two first insertion parts 600, respectively. Engage the second elastic retaining ring 610 on the first insertion part 600 corresponding to the first pressure cover 200, so that the second elastic retaining ring 610 is located on the outer side of the third insertion part 1200 away from the arc-shaped block 400, to prevent the third insertion part 1200 from coming out.
[0030] Disassembly process: First, remove the second elastic retaining ring 610 from the first insertion part 600 corresponding to the first pressure cover 200, and then remove the outer third insertion part 1200. Then, use calipers to twist the second pressure cover 300 to remove it. Since the third insertion part 1200 between the first insertion part 600 and the second insertion part 1100 is not removed, the first pressure cover 200 will not rotate with the second pressure cover 300 when it is twisted. After removing the second pressure cover 300, remove the other third insertion part 1200, and then use calipers to twist the first pressure cover 200.
[0031] When performing maintenance, repairs, or parts replacement on the idler rollers, which requires disassembly, the first cover 200 can easily rotate along with the second cover 300 when the operator uses tools such as calipers to tighten the second cover 300. This causes disassembly to be inconvenient. By addressing this issue, the third connector 1200 between the first and second cover 200 is located on the outer side. Furthermore, by not removing the inner third connector 1200 when tightening the second cover 300, the first cover 200 will not rotate with the second cover 300, thus resolving the problem of the first cover 200 rotating with the second cover 300 and causing disassembly inconvenience.
[0032] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably, and the embodiments can be combined with each other. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to in the method section.
[0033] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
