[0002] The belt is one of the important parts of the mining belt conveyor. The mining belt conveyor is an important mining equipment, mainly used for horizontal, inclined and vertical transportation of materials such as ore and coal.

[0003] The working principle of the mining belt conveyor is to transport materials through the circular motion of the conveyor belt. When the conveyor belt is started, the drive device drives the roller to rotate, so that the conveyor belt drives the materials to move together. The materials are transported on the conveyor belt through the action of gravity, friction and other forces. During the transportation process, the tightness and tension of the conveyor belt are ensured by adjusting the tensioning device to avoid problems such as deviation of the conveyor during operation. In order to solve the problem of belt deviation, it is necessary to install a belt deviation correction device on the conveyor.

[0004] The passive hydraulic belt deviation correction device is a technical device that uses hydraulic transmission to tighten the roller to correct the belt deviation and maintain lateral stability. This device has adaptive performance and can automatically adjust the deviation correction force according to the speed, tension and specifications of the belt, thereby ensuring the stable operation of the belt.

[0005] Since the surface of the conveyor belt is prone to adhesion after long-term use, too much adhesion will increase the conveying pressure of the conveyor belt and cause damage to the equipment. Manual cleaning not only has poor cleaning efficiency but is also very laborious. Utility Model Content

[0011] In order to achieve height adjustment of the scraper, as a preferred embodiment of the passive hydraulic belt deviation correcting device with a cleaning structure of the utility model, a hydraulic lifting structure is formed between the movable bracket and the telescopic rod.

[0023] See also Figure 1-Figure 5 The utility model provides the following technical solutions: a passive hydraulic belt deviation correction device with a cleaning structure, comprising a truss 1, a roller support 2, a belt roller 3 and a belt 4, the upper surface of the truss 1 is connected to the roller support 2, the surface of the roller support 2 is installed with the belt roller 3, and the surface of the belt roller 3 is provided with the belt 4; the side surface of the truss 1 is connected to a first transverse plate 5, the upper surface of the first transverse plate 5 is installed with a rotating shaft 6, the surface of the rotating shaft 6 is connected to a deviation correction bracket 7, and the end of the deviation correction bracket 7 is connected to a limited A positioning card shell 8 is provided, and a conveying roller 9 is installed inside the limiting card shell 8. A spring bar 10 is connected between the correcting bracket 7 and the first horizontal plate 5. The side surface of the truss 1 is connected to the second horizontal plate 11, and a telescopic rod 12 is installed on the upper surface of the second horizontal plate 11. The telescopic end of the telescopic rod 12 is connected to a movable bracket 13, and the end of the movable bracket 13 is connected to a support arm 14. A guide rod 15 runs through the inside of the support arm 14, and the guide rod 15 is connected to the upper surface of the truss 1. The side surface of the support arm 14 is connected to a scraper 16.

[0024] It should be noted that the passive hydraulic belt system used in this equipment is a technology that uses the hydraulic transmission principle to convert internal mechanical energy into hydraulic energy and then into mechanical energy to control the operation of the belt 4 and automatically correct the deviation.

[0025] Preferably, the deviation-correcting bracket 7 forms a rotating structure with the first transverse plate 5 through the rotating shaft 6 .

[0026] Preferably, the spring bars 10 are symmetrically arranged on both sides of the deviation-correcting bracket 7 , and an elastic telescopic structure is formed between the deviation-correcting bracket 7 and the spring bars 10 .

[0027] During specific use, when the deviation correction bracket 7 rotates, the spring bar 10 will be deformed. At this time, the spring bar 10 can drive the deviation correction bracket 7 to reset through its own elastic force, so that the belt 4 can be reset through the limit card shell 8 and the conveying roller 9, so that the deviation of the belt 4 can be corrected.

[0028] Preferably, the limiting card shell 8 and the conveying roller 9 are symmetrically arranged at two ends of the deviation correcting bracket 7 .

[0029] During specific use, when the belt 4 deviates during the conveying process, the belt 4 will generate a force on the conveying roller 9 and the limit clamp 8, and the limit clamp 8 can drive the deviation correction bracket 7 to rotate under the force.

[0030] Preferably, a hydraulic lifting structure is formed between the movable bracket 13 and the telescopic rod 12 .

[0031] When in use, the telescopic rod 12 can be retracted during operation. When the telescopic rod 12 is retracted, the support arm 14 can be driven to move downwards through the movable bracket 13. When the support arm 14 moves downwards, the scraper 16 can be driven to move downwards.

[0032] Preferably, the support arm 14 and the guide rod 15 are symmetrically arranged on both sides of the movable bracket 13, and the support arm 14 and the guide rod 15 are slidably connected.

[0033] During specific use, the support arm 14 can slide on the surface of the guide rod 15 when a force is applied, so that the movement direction of the support arm 14 can be limited.

[0034] Working principle: When using the passive hydraulic belt deviation correction device with a cleaning structure, firstly, the limit card shell 8 drives the conveying roller 9 to be sleeved on both sides of the belt 4. When the belt 4 deviates during the conveying process, the belt 4 will exert a force on the conveying roller 9 and the limit card shell 8. The limit card shell 8 is subjected to the force and can drive the deviation correction bracket 7 to rotate on the surface of the rotating shaft 6. When the deviation correction bracket 7 rotates, it drives the spring bar 10 to deform. At this time, the spring bar 10 can drive the deviation correction bracket 7 to reset through its own elastic force, so that the belt 4 can be reset through the limit card shell 8 and the conveying roller 9, so that the auxiliary deviation correction of the belt 4 can be achieved.

[0035] When the surface of the belt 4 is adhered with adhesions and needs to be cleaned, the telescopic rod 12 can be operated, and the telescopic rod 12 can be retracted when operating. When the telescopic rod 12 is retracted, the movable bracket 13 can be driven to move downward, and the movable bracket 13 can drive the support arm 14 to move downward, and the support arm 14 can drive the scraper 16 to move downward. When the scraper 16 moves downward to be close to the upper surface of the belt 4, the telescopic rod 12 stops operating. In this way, the adhesions can be scraped off by the scraper 16 during the transmission of the belt 4, and the adhesions can be transmitted to the end and dropped from the end during the transmission of the belt 4.

[0036] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
