ABSTRACT:
A vacuum grain moving apparatus connected to a three-point hitch of a tractor and operated with the power take-off drive of the tractor. The apparatus has a grain holding tank connected to a grain collection hose used to carry grain and air to the tank. An air moving unit mounted on the tank has a rotatable power driven impeller that draws air from the center of the chamber of the tank to provide a vacuum pressure within the tank. The impeller has first and second generally radial blades that pump the air from the tank chamber. An auger conveyor operatively associated with the lower end of the tank moves the grain from the tank into a transport vehicle. The auger conveyor has a driven helical auger located within a tube. The tube extends beyond the outer end of the auger and retains a plug of grain in the tube to inhibit back flow of air into tank chamber during the running of the air moving unit. A swinging gate pivotally mounted on an outer end cap normally closes the exit opening of the tube. The closed gate restricts reverse flow of air in the tube during the starting period of the apparatus.
