Abstract
Self-cleaning apparatus for removing material from a rotating drum. Buckets are associated with a scraper which is maintained in a substantially fixed position relative to the local gravitational force vector. The scraper is maintained in said position by means of a counterweight. A scraping action is achieved as the drum and buckets rotate.
