Description

Technical Field

[0001] The utility model relates to the technical field of coal mine production, in particular to a coal mine belt conveyor anti-deviation structure. Background Art

[0002] Conveyor belts are often needed to transport mined coal over long distances. During the use of the belt conveyor, the conveyor belt on the belt conveyor is prone to deviation due to the long distance. Therefore, professional staff are required to regularly adjust and maintain the belt conveyor. If it is not maintained, the conveyor's operating stability will be poor.

[0003] However, most of the anti-deviation structures of coal mine belt conveyors currently use materials such as coal mines. Due to the characteristics of the materials themselves, the belts will still deviate when they are poured into the belt conveyor. The staff are required to frequently perform deviation adjustment and maintenance, which is rather cumbersome.

[0004] In the announcement number CN214454520U, a device for preventing a belt conveyor from running off the track in an underground coal mine is disclosed. The device comprises a base, two groups of electric rollers, a conveying belt and several groups of limiting devices. Two groups of vertical wing plates are symmetrically arranged on the base, mounting seats are arranged at both ends of the base, the two groups of electric rollers are rotatably mounted on the mounting seats at both ends of the base, the conveying belt tensioning sleeves are arranged on the two groups of electric rollers for conveying coal, limiting ribs are arranged on both sides of the conveying belt, and several groups of limiting devices are symmetrically fixedly mounted on the two groups of vertical wing plates for cooperating with the limiting ribs to limit the conveying belt in a direction perpendicular to the conveying direction.

[0005] Although the above patent can reduce the number of belt edge grinding times, save equipment maintenance costs, and improve the conveying stability of the belt conveyor; however, the device is not equipped with a dust reduction mechanism. A large amount of coal dust and particulate matter will be generated during coal mining operations. If these particulate matter are not treated, they will be suspended in the air and affect the health and respiratory system of the workers.

[0006] Therefore, it is necessary to propose a coal mine belt conveyor anti-deviation structure to solve the above problems. Utility Model Content
