Self-propelled overhead livestock enclosure washing system

An enclosure washing system for cleaning portions of an interior space of a livestock confinement building, the enclosure washing system comprising:

• a guide track assembly for positioning in an elevated condition above a floor of the livestock confinement building, the guide track assembly defining a path;
• a mobile spray assembly engaging the guide track assembly such that the mobile spray assembly is suspended and supported in an elevated position above the floor of the livestock confinement building and is movable along the guide track assembly along the path, the mobile spray assembly comprising:
• a frame;
• a movement mechanism mounted on the frame and configured to move the spray assembly along the guide track assembly, the movement mechanism comprising:
• a pair of movement wheels rotatably mounted on the frame and positioned to engage the track assembly such that rotation of at least one of the movement wheels causes the mobile spray assembly to move along the guide track assembly;
• a movement motor configured to rotate at least one movement wheel of the pair of movement wheels, the movement motor being mounted on the frame;
• a nozzle mechanism configured to disperse a cleaning fluid from the mobile spray assembly into the interior space of the livestock confinement building, the nozzle mechanism including a nozzle to dispense the cleaning fluid into the interior space;
• and
• a fluid supply assembly configured to provide cleaning fluid to the mobile spray assembly, the fluid supply assembly forming a fluid path from the cleaning fluid source, the fluid supply assembly being supportable on the floor of the livestock confinement assembly below the elevated position of the mobile spray assembly, the supply assembly comprising:
• a supply conduit for conducting the cleaning fluid from the fluid supply assembly to the mobile spray assembly, the supply conduit having a segment extending from the fluid supply assembly on the floor of the livestock confinement building to the mobile spray assembly in the elevated position above the floor, the segment comprising a flexible hose permitting movement of the mobile spray assembly on the guide track assembly while the fluid supply assembly remains stationary on the floor of the livestock confinement building.
