Description

Technical Field

[0001] The utility model relates to the technical field of idlers, in particular to an idler for a mine machinery conveyor. Background Technique

[0002] In mine exploitation, the conveying of minerals is usually completed by a conveyor. A conveyor is a material handling machine that continuously conveys materials on a certain line, also known as a continuous conveyor. The conveyor can perform horizontal and inclined conveying, and can also form a spatial conveying line. The conveying line is generally fixed. In order to increase the mineral conveying capacity and protect the conveying belt of the conveyor, idlers are usually installed at equal distances at the bottom of the conveying belt.

[0003] However, when some existing idler mechanisms are in use, they lack an adjustment function, and it is not convenient for people to adjust the height of the idler, which easily leads to inconvenience in tightening the conveyor belt when it is loose. At the same time, it is also inconvenient to adjust the use width and angle of the idler, resulting in only being able to adapt to a single conveyor belt, which is not convenient for personnel to work. Therefore, in view of the above problems, an idler mechanism for a mine machinery conveyor is specifically proposed. Content of the Utility Model
