Poultry house cleaner apparatus

Mobile poultry house cleaner apparatus for scraping poultry manure and droppings from elongated parallel floor level receiving pits extending along parallel transversely spaced paths over the length of an elongated poultry house and disposed below rows of overhead poultry cages, the elongated receiving floor pits being of substantially rectangular cross-sectional configuration corresponding to the width of the cages of the associated row with intervening and flanking floor surface lanes coextensive longitudinally with and located between an outboard of the the pits, the apparatus comprising a transversely elongated main frame transversely spanning substantially the width of the poultry house having opposite ends to overlie the flanking floor lanes and a central portion overlying an intervening floor lane, a respective pair of wheels rotatably supported in depending relation from said main frame adjacent said opposite ends and said central portion forming plural pairs of outboard wheels to track on a plurality of said lanes, a driver's station and an engine and control therefor adjacent said station each surmounted on said main frame, output gear box means driven by drive means powered by the engine and having output shafts extending therefrom driving a chain sprocket at each of the opposite ends of the main frame, a pair of traction chains respectively located adjacent said opposite ends extending the length of the poultry house at floor level and anchored at opposite ends thereof to the building floor adjacent side walls of the poultry house, the chains being trained about said chain sprockets whereby rotation of the chain sprockets driven by said output shafts causes the sprocket to track along the chains and concurrently drive the opposite ends of the main frame to translate the main frame the length of the poultry house while maintaining predetermined transverse alignment relative to the receiving pits, and a plurality of scraper blade assemblies spaced widthwise along the main frame respectively aligned with and extending into the receiving pits, means to draw the scraper assemblies along their respective receiving pits upon movement of the main frame along the length of the poultry house, and remote controlled lift means for raising the scraper blade assemblies out of contact with the bottom and sides of the associated pits and lowering the same into contact therewith.
