Patent ID: 7303362

Claim:
An automotive, self-propelled granular material handling mechanism comprising: a chassis carrying an engine and a drive train powered by said engine, said drive train including ground-engaging traction wheels for moving said chassis; a hydraulic system power driven upon said chassis, said hydraulic system including a pump, a hydraulic fluid reservoir, and conduits for communicating hydraulic fluid pressurized by said pump to receivers therefor; an air compressor power driven upon said chassis for receiving ambient air and providing regulated pressurized air for conveying granular material; a loading hopper with a top opening receiving granular material and a bottom opening directing granular material from said loading hopper; an auger associated with said bottom opening of said loading hopper providing a flow of granular material as a steady even stream; a rotary air lock pump mechanism receiving said steady even stream of granular material; and also receiving pressurized air from said air compressor for discharging said granular material by force of pressurized air along a discharge conduit; and a long flexible hose connecting said discharge conduit to a distant location to place said granular material ejected from said rotary air lock pump mechanism at said distant location wherein said screw auger has upwardly of its receiving portion an additional screw auger portion of reverse flighting.
