Abstract
A conveyor belt scraping apparatus comprises a blade having a blade edge biased against a conveyor belt. The blade is supported at its base and has a web extending from the base to support the blade edge. The web has at least one groove therein substantially parallel to the blade edge to define a tensioning region at the narrowed region of the web, whereby the blade may be biased and tensioned without need for external biasing and tensioning arrangements. Preferably, there are plural grooves in the web. Also preferably, the plural grooves are of different sizes so as to provide a progressive rate to the spring characteristic of the tensioning region of the web. In addition, a groove may have a cushioning material therein so as to provide cushioning of the blade.
