Abstract
In a self cleaning enclosure for production of livestock including hogs an enclosed slightly conical circular surface is disclosed which includes a scraper extending radially outward over the enclosed surface and rotational over the surface to effect cleaning and sanitization of the surface. The scraper includes a conveyor system out of direct contact with the surface which carries the waste material outward along the scraper to a trench encircling the enclosed surface and serving as a depository for the waste. A trench scraper is carried with the surface scraper, and extends into the trench for moving the waste to a localized outlet for removal of the waste from the trench. A motor caused rotation of the scraper around the surface and also causes operation of the conveyor system.
