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. Preferably, the blade mount is of a shape retentive metal material so that it retains its bias force applied to cleaner blade even in high temperature and high loading conveyor belt applications. To keep the complexity of the blade mount to a minimum, it is preferably of a one-piece, angled spring plate construction including a base integral with the layback arm interconnected thereto by the arcuate portion.
