Cleaning device used for belt conveyor and crushing and screening equipment conveyor

The invention discloses a cleaning device used for a belt conveyor and a crushing and screening equipment conveyor. The cleaning device comprises a scraping plate, elastic tensioning devices and a positioning plate; the two sides of the scraping plate are each fixedly connected with one elastic tensioning device, the positioning plate is matched with the elastic tensioning devices to achieve synchronous rotation on a rack, a push and pull part is further included, and is connected with the positioning plate, through the push and pull part, the positioning plate can be pulled upwards or pusheddownwards, the positioning plate drives the elastic tensioning devices and the scraping plate to rotate, and the distance between the scraping plate and a conveying belt is changed. The angle of a cleaner can be flexibly adjusted, the angle adjusting range is large, and after adjusting to be in place, positioning locking is carried out. 本发明公开了一种用于带式输送机的清扫装置及破碎筛分设备输送机，清扫装置包括刮板、弹性张紧装置和定位板；在所述刮板两侧各固接有一个弹性张紧装置，所述定位板与弹性张紧装置配合实
