Abstract
A replaceable conveyor scraping blade has a blade body extending lengthwise along a longitudinal axis. The blade body is produced from a material having a flexible, elastic quality. The blade body comprises a base portion, and intermediate portion, and a terminal end. The base portion is attachable to a tensioning device for biasing the blade body against a conveyor belt. The intermediate portion is generally arcuate and comprises a leading surface and a trailing surface. The leading surface extends upwardly relative to the base portion. The trailing surface is opposite the leading surface. It also extends upwardly relative to the base portion and has a scalloped surface when viewed in cross-section extending lengthwise along the longitudinal axis. The terminal end has a scraping surface separating an uppermost portion of the trailing surface from an uppermost portion of the leading surface.
