ABSTRACT:
A conveyor belt scraper has an elongate supporting frame that supports an elongate blade guided to move laterally with respect to the supporting frame in a direction towards a belt to be scraped. The blade is urged into engagement with the belt by at least one elongate element that is at least partly flexible and at least partly longitudinally resilient. Structure is provided for tensioning the elongate element. Various arrangements for the elongate element in relation to the blade and construction of the elongate element are disclosed. The conveyor belt scraper also has structure for mounting two or more scraper blades so that the force with which they engage the belt to be scraped is substantially equalized.
