ABSTRACT:
A conveyor belt cleaning assembly including at least one generally transversely extending cleaning device, engaging, in an operative position, a conveyor belt surface to be cleaned. The cleaning device includes a plurality of wear resistant scraper elements supported by a flexible tension member and resilient spacer coils coupled between the tension member and scraper elements for compressively engaging and yieldably maintaining the scraper elements at separate scraper positions along the tension member. Cable strand damage caused by pinching engagement of the scraper elements in response to deflection movement is reduced by mechanically decoupling the spacer coil end turns with respect to the cable. The scraper elements are mechanically engaged by oversized compression coils and spacer sleeve combinations, with scraper element deflection forces being reacted by axial compression of the spacer coils.
