Description

Technical Field

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

[0002] When materials are transported by belt conveyors, sometimes materials may spill into the inner side of the closed belt, that is, the inner circumference that fits the belt roller. Due to the effects of gravity and friction, the deposits on the inner side of the belt will increase over time, increasing the movement resistance. Especially for products like gypsum, which have extremely strong viscosity, the adhesion of the material makes it adhere to the belt and not easy to fall off, increasing the power load of the conveying motor. In severe cases, it will cause the belt to deviate, thus affecting work efficiency.

[0003] Traditional scrapers will wear out due to friction with materials on the belt conveyor when used for a long time. When the scraper is worn to a certain extent, the scraper plate needs to be replaced. However, due to the uneven distribution of materials on the belt conveyor, the scraper plate will not wear evenly. Some parts of the scraper plate are severely worn, while other parts are less worn and have not yet reached the replacement standard.

[0004] In the prior art, when replacing a scraper plate, the entire scraper plate is replaced, so that the less worn position is replaced together, resulting in waste of the scraper plate and increased use cost. Utility Model Content
