[0001] The utility model relates to the technical field of belt conveyor, especially to the field of the cleaning of the conveyor belt of the belt conveyor, and specifically relates to a vibrating type patting sweeper for belt conveyor. BACKGROUND

[0002] The belt conveyor is a common material conveying equipment, which conveys materials through the rotation of the conveyor belt and discharges the materials from the end of the conveying process. However, if the conveyed materials have certain viscosity, the materials cannot be completely discharged, resulting in that the materials adhere to the surface of the return conveying belt. When used for a long time, the load of the conveyor is increased, and the adhered materials can damage the conveyor belt, such as accelerating aging and cracking.

[0003] In order to solve the problem of the materials adhering to the return conveying belt, a sweeper is usually arranged on the belt conveyor to clean the materials adhering to the return conveying belt. At present, the common sweeper mainly adopts the structure of a scraper, which scrapes the adhered materials by using the scraper structure fixed on the rack of the belt conveyor. Although the sweeper has a certain cleaning effect, the wear of the conveyor belt is relatively serious, which is not conducive to prolonging the service life of the conveyor belt. Therefore, in actual application, the scraper with poor wear resistance is selected to reduce the wear of the conveyor belt, but the scraper needs to be frequently replaced, which increases the number of shutdowns and is not conducive to improving the production efficiency.

[0010] As an optimization, the arc surface of the friction wheel is provided with a patterned rubber surface, and the patterned rubber surface is circumferentially closed.
