[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] See also Figures 1 to 5 The utility model provides a belt installation mechanism with an external bearing. The belt installation mechanism is used for a sealed belt conveyor, and can support the belt in the sealed belt conveyor. At the same time, the bearings connected to the rollers are externally placed, which not only improves the safety performance of the sealed belt conveyor, but also makes it easy to find that the supporting rollers do not support the belts, so as to repair the roller components in time. At the same time, when the bearings are externally placed, the sealed belt conveyor can maintain good sealing performance, avoiding the situation where dust escapes when the sealed belt conveyor transports materials and pollutes the environment.

[0027] In this specific embodiment, a belt mounting mechanism with an external bearing is used for a sealed belt conveyor. The belt mounting mechanism includes a plurality of supporting units connected in sequence, and the supporting unit includes a mounting seat 1, a roller assembly 2 and a closing assembly 3. The mounting seat 1 has a cavity therein and openings at both ends. The mounting seat 1 is provided with at least two through-hole groups, and the through-hole groups include through holes 11 respectively provided on opposite sides of the mounting seat 1; at least two of the roller assemblies 2 are connected to the mounting seat 1, and the roller assembly 2 includes at least one A support roller 21 and a bearing seat 22, wherein the opposite ends of the support roller 21 are respectively connected to the two bearing seats 22 via bearings, and the two bearing seats 22 are arranged on the opposite sides of the outside of the mounting seat 1, so that the support roller 21 is straddled in the cavity and the opposite ends are respectively penetrated in the two through holes 11, and the axes of the two support rollers 21 of the two roller assemblies 2 are parallel to each other; the opposite ends of the support roller 21 are both sleeved with the closing assembly 3, and the closing assembly 3 is fixedly connected to the outer wall of the mounting seat 1 to close the through hole 11.

[0028] During actual use, the conveying section of the sealed belt conveyor is modified, and a belt installation mechanism with an external bearing is adopted. The belt in the sealed belt conveyor is supported by the roller assembly 2, which can improve the safety performance of the sealed belt conveyor and can easily detect the situation where the support roller 21 does not support the belt, so as to timely repair the roller assembly 2. At the same time, the closing component is fixedly connected to the outer wall of the mounting seat 1 to close the through hole 11, ensuring that the mounting seat 1 maintains good sealing performance when the bearing is external, thereby avoiding dust escape during material transportation to pollute the environment.

[0029] In this specific embodiment, the two bearing seats 22 are fixedly connected to the mounting seat 1 by screws, and the closing component 3 is fixedly connected to the mounting seat 1 by screws.

[0030] In order to facilitate the disassembly of the roller assembly 2 as a whole for maintenance, on the basis of the above scheme, the bearing seat 22 can be passed through the cavity through the through hole 11. It is only necessary to remove the screws to separate the two bearing seats 22 from the mounting seat 1, and the roller assembly 2 can be pulled out of the through hole 11 as a whole.

[0031] On the basis of the above scheme, since the roller assembly 2 can be pulled out from a through hole 11 as a whole, the inner diameter of the through hole 11 is relatively large. If the through hole 11 is not sealed, the sealing performance of the sealed belt conveyor will inevitably be reduced.

[0032] It should be noted that the sealing component 3 is not limited to a specific structure. The sealing component 3 only needs to be able to seal the through hole 11, and no limitation is made here.

[0033] In this specific embodiment, the closing assembly 3 includes a sealing plate 31, on which a movable gap 32 and a connecting hole 33 connected to the movable gap 32 are provided, one end of the supporting roller 21 is inserted into the connecting hole 33, and the sealing plate 31 is fixedly connected to one side of the mounting seat 1.

[0034] It should be noted that the circumferential side of the sealing plate 31 is fixedly connected to the mounting base 1 by screws, and the sealing plate 31 has plasticity or elasticity. After the roller assembly 2 is installed, the movable gap 32 is pried open so that one end of the support roller 21 can be inserted into the connecting hole 33, and the inner diameter of the connecting hole 33 is slightly larger than the inner diameter of the support roller 21.

[0035] In one embodiment, the sealing plate 31 is an elastic plastic plate. In this specific embodiment, the sealing plate 31 is an elastic rubber plate.

[0036] On the basis of the above scheme, the roller assembly 2 includes two support rollers 21 , one end of each of the support rollers 21 is connected to the two bearing seats 22 via bearings, and a movable channel 20 is formed between the other ends of the two support rollers 21 .

[0037] It should be noted that the belt in the partially sealed belt conveyor is a sidewall conveyor belt, and the edges of the sidewall conveyor belt are supported by the two support rollers 21, so that the hopper part on the sidewall conveyor belt can be located in the movable channel 20.

[0038] In this specific embodiment, flanges 10 are provided at opposite ends of the mounting seat 1, and a plurality of threaded holes are provided on the flanges 10. The open ends of the two mounting seats 1 of two adjacent support units are fixedly connected by screws matching the threaded holes.

[0039] In order to improve the sealing performance of the connection between two adjacent mounting seats 1 , an elastic sealing gasket may be provided between the open ends of the two adjacent mounting seats 1 .

[0040] In this specific embodiment, the mounting seat 1 is made of an alloy plate, and the supporting roller 21 is a rubber roller. The alloy plate is light in weight, relatively high in cost, and can reduce the cost of the belt mounting mechanism.

[0041] On the basis of the above solution, a sound-absorbing cotton layer is provided on the inner wall of the mounting seat 1. It should be noted that the sound-absorbing cotton layer can absorb the noise generated when the belt and the supporting roller rotate.

[0042] In one embodiment, the number of the roller assemblies 2 is 2-6. In this specific embodiment, the number of the roller assemblies 2 installed on the mounting seat 1 is 4, and two of the roller assemblies 2 are located above the other two of the roller assemblies 2.

[0044] Compared with the prior art, the utility model provides a belt installation mechanism with external bearings, at least two roller assemblies are connected to the mounting seat, the roller assembly includes at least one support roller and a bearing seat, the opposite ends of the support roller are connected to the two bearing seats via bearings, respectively, the two bearing seats are arranged on opposite sides of the outside of the mounting seat, the support roller is straddled in the cavity of the mounting seat and the opposite ends are respectively penetrated in the two through holes, and the axes of the two support rollers of the two roller assemblies are parallel to each other. By externalizing the bearings, the safety performance of the sealed belt conveyor is improved, and it is easy to find that the support rollers do not support the belt, so as to repair the roller assemblies in time. At the same time, the opposite ends of the support rollers are sleeved with closing assemblies, which are fixedly connected to the outer wall of the mounting seat through the closing assemblies to close the through holes; when the bearings are externalized, the mounting seat maintains good sealing performance to avoid dust escaping during material transportation and polluting the environment.
