<p>A frame having a passageway is movably mounted on retractable wheels. A removable tongue is connected to the frame for transporting the spray machine. A spray system is mounted on a spray arch having a plurality of nozzles along its length and the spray arch is provided with sleeves at the bottom ends of its legs for slidably engaging vertical posts in the frame whereby the spray arch may be selectively vertically adjusted. The posts are provided with horizontal sleeves slidably connected to horizontal members of the frame for horizontally adjusting the position of the spray arch. The spray for the spray system is supplied from a tank mounted on the frame which in turn is connected to a pressurized air tank. An actuating wand extends transversely across the passageway through the frame to be engaged by an animal and maintain contact with the animal along its entire length such that that the animal will be sprayed. The movement of the actuating arm causes the spray system to function when moved only parallel to the length of the passageway in one direction only. The passageway may be substantially enclosed by a cover being provided over the frame thereby providing inducement for animals to enter the passageway.</p> |
