ABSTRACT:
A conveyor belt scraper in which a row of scraping blades 38 is held clamped between upper flanges 30,30' of a resilient buffer 28,28'. Lower flanges 32,32' of the buffer are secured to opposite sides of a flange 40 of a supporting beam 42. Bowed side walls 34,34' of the buffer, extending between the lower flanges and the upper flanges, form a hollow structure housing the beam 42. The hollow structure is oversize compared with the beam cross-section so as to leave clearance space 46 between upper surfaces of the beam and upper portions of the buffer. The buffer components are moulded of rubber and some movement of the resiliently-supported blades, in a direction toward and away from the conveyor belt, is permitted by compression of the hollow structure into the clearance space 46.
