[0001] The utility model relates to the technical field of belt conveyor equipment, in particular to an automatic belt attachment cleaning device. Background Art

[0002] The main purpose of using belt conveyors in coal mines is to improve the production efficiency and safety of coal mines. Belt conveyors in coal mines are usually used to transport coal from the mining site to other areas. Since spray dust reduction is often used when the coal transported by the belt conveyor is mined again, the coal contains a certain amount of moisture. The presence of moisture causes the coal to easily adhere to the surface of the belt, thereby increasing the load on the belt and reducing the service life of the belt. As time goes by, the belt will have an unbalanced load distribution. This unbalanced load causes the belt to deviate, further affecting the stable operation of the belt conveyor, causing the belt to derail, affecting the normal operation of the belt conveyor, causing equipment failure, and even shutdown, thereby affecting the overall production efficiency. Therefore, how to effectively reduce the impact of coal moisture on the operation of the belt conveyor and improve equipment cleaning efficiency has become an urgent problem to be solved in the current coal transportation field.
