Technical Field

[0001] The utility model belongs to the technical field of conveying devices, and more specifically, particularly relates to a coal scraping mechanism for a coal conveying belt. Background Art

[0002] In thermal power plants, conveyor belts are needed to transport coal. Some coal powder or coal slag in the coal will gather on the outer surface of the belt. When the belt rotates, some coal powder will fall on the inner end of the belt. This causes the belt to swing when transporting coal. Therefore, the belt needs to be cleaned regularly.

[0003] The existing conveyor belt cleaning device has some disadvantages in use:

[0004] First, when the belt is transporting coal, the belt itself is elastic. When the scraper is cleaning the coal on the belt surface, the belt is prone to move inwards under the pressure of the scraper, making it difficult to ensure that the scraper and the belt are always in close contact, resulting in poor cleaning effect.

[0005] Secondly, some existing coal scraping mechanisms only clean the outside of the belt, and when the belt is running, part of the coal powder will fall to the inner end surface of the belt, causing slippage between the belt and the conveyor belt. Utility Model Content
