Abstract:
A cleaner for conveyor belts comprising:a scraper blade for engaging against a conveyor belt running in a downstream travel direction; a blade mount member that resiliently keeps the blade engaged against the belt; a layback portion of the mount member having an upper end including a flat surface to which the scraper blade is secured and extending at a predetermined layback angle toward the belt for a predetermined distance; and a lower arcuate portion of the mount member spaced upstream of the upper end of the layback portion with the lower arcuate portion flexing during conveyor belt operations and having a predetermined radius of curvature that is minimized relative to the distance the layback portion extends so that the layback portion has a relatively long length for providing controlled deflections of the layback portion as a result of high impact forces against the scraper blade that reduces loading on the scraper blade and substantially keeps the scraper blade engaged against the belt as the belt is running, wherein the scraper blade includes a tip of hard material for engaging the belt.
