Description

Technical Field

[0001] The utility model belongs to the technical field of conveying machinery, and in particular relates to a conveyor belt scraping device. Background Art

[0002] During the fertilizer production and transportation process, the raw materials between production components are transported by belt conveyors, which are transported by oil conveyor belts. The conveyor belts are composed of oil-immersed drum motors, drums, supporting drums, belts, belt connecting buckles, and brackets. The front drum motor and the rear drum are fixed by brackets, and the belt connected by belt buckles is driven to circulate around the drum and motor under the support of the small drum. Because the transported materials have a certain amount of moisture and adhesion, some raw materials will adhere to the conveyor belt. When the belt returns, it will fall due to gravity or fall in pieces after being crushed by the supporting small drum. This not only affects the workshop environment, but also requires manual cleaning, and it is a waste of repeated production energy. For this reason, an improved conveyor scraper device is designed.
