Abstract
A conveyor belt cleaner is provided that is particularly well-suited for high temperature applications. The cleaner includes a blade mount that has a layback arm mounting the cleaning blade and which can simultaneously deflect horizontally and vertically via changes in the radius of curvature of a lower arcuate portion connected thereto so as to minimize stress on the blade mount. The layback arm extends toward the conveyor belt at an acute layback angle relative to the immediately upstream belt surface. In another aspect, a belt cleaning system is provided including a plurality of resilient blade mounts that absorb the energy of impacts with the cleaning blade so as to allow for controlled release of the impact energy upon bringing the blade quickly back into scraping engagement with the belt. Preferably, two of these resilient mounts are associated with each blade in the belt scraping area and the others at ends of an elongate support laterally spaced from the scraping area.
