Abstract
A belt scraper for cleaning the conveyor belt on a cylindrical pulley including a plurality of scraping blades having transverse scraping edges at the leading end of the blade side surface which faces the conveyor belt. The side surfaces are tangential to and resiliently against the belt by a transverse rotary shaft parallel to the scraping edge. A separate blade support element connects each blade to the shaft so that the blades extend across the belt width, and includes a torsion element providing an additional point of rotation between the scraping blade and the rotary shaft located transverse to force the blade to pivot away from the belt surface upon impact by an object moving with the belt into engagement with the blade against the scraping edge.
