Description

Technical Field

[0001] This utility model belongs to the technical field of coal conveyor belt cleaning structure design, specifically relating to an adjustable angle cleaner. Background Technology

[0002] Belt conveyors are widely used in various fields of social production as the main tool for material transportation, such as coal, ore, grain, and chemical industries. Especially in the production process of coal mining enterprises, belt conveyors are important equipment connecting various production links such as coal mining and coal transportation. However, during the use of belt conveyors, a large amount of coal material often adheres to the surface of the conveyor belt. Therefore, it is necessary to use a conveyor belt cleaner to clean the material on the surface of the conveyor belt regularly.

[0003] However, most common conveyor belt cleaners on the market use fixed cleaning brushes, the angle of which cannot be adjusted. Therefore, in actual use, the contact between the cleaning brush and the conveyor belt cannot be adjusted according to actual needs. If the contact force is too large, it can easily damage the conveyor belt; if the contact force is too small, it will result in poor cleaning effect and failure to completely remove the material adhering to the surface of the conveyor belt. To address these issues, we provide an adjustable-angle cleaner. Utility Model Content
