Abstract
A circular area is provided having the floor sloping inwardly towards the center and having manure and urine disposal means within the center. A boom is pivotally mounted by one end thereof in the center and extends radially outwardly to the outer boundary of the area to be cleaned and a scraper component is supported by the boom and contacts the floor surface. The boom is operatively connected to a source of power for rotating same and the scraper is either straight or curved with the inner end secured at a point offset from the axis of the boom pivot so that when rotated, the outer end of the scraper is in advance of a radius line extending upwardly from the pivot and the inner end of the scraper is behind the same radius line extending from the pivot. An alternative embodiment provides a floor sloping outwardly from the central pivot to an annular sump or collector under which circumstances, the relation of the scraper is reversed. The scraper or the boom may be provided with floating mounting means to facilitate continuous contact with the floor surface. With the scraper crossing radius lines at an angle, in conjunction with the sloping floor surface, any debris or manure scraped from the floor surface is automatically urged towards the collecting sump. An alternative embodiment includes means mounted on the boom to spray water/disinfectant onto the floor as it is being scraped and cleaned.
