ABSTRACT:
A method of forming a grain pile by pushing grain into a buried insertion point. A screw conveyor grain at ground level from a receiving point to the buried insertion point. The screw conveyor creates a pile core at the insertion point and forcibly enlarges the pile core into a large pile against forces of natural resistance. Piles as large as 2,000,000 bushels can be formed by a conveyor having a drive motor of less than 50 horsepower. Grains of different properties may be formed into a pile and become blended as a consequence thereof.
