Method and apparatus for efficiently filling and unloading flat and hopper bottom grain bins from the bottom using one conveyor

A method of moving granular materials comprising the steps

• a. using a horizontal screw auger conveyor powered by a drive system causing it to rotate in the proper direction for pushing granular materials and products, such as grain, seeds, pellets, and other granular particulate matter, either biological products or manufactured products that enter the conveying device through an inlet hopper or receiver,
• b. the material moves through auger tube pushed by an auger screw connected by a coupling to an auger power unit powered by an electric motor through a drive speed reducer,
• c. a elbow which turns the grain from horizontal to vertical flow with minimal frictional resistance, where the grain begins to flow upward in a core of moving grain through static grain resulting in a continuous rising grain cone pile surface,
• d. the grain is propelled upward by the pressure from following grain materials until it reaches the desired surface level, wherein continually pushing of grain through the horizontal base conveyor tube and elbow forcing the grain to flow upward through a loose center core with grain spilling out and slowly trickling down the continually rising grain bulk slope surface where the grain flows down the face of the pile at the natural angle of repose for the specific grain material.

A method for moving granular materials, including without limitation grain, into various types of storage structures and removing said granular materials using the same conveying system comprising

• a. a storage structure with a base, sidewalls to contain the granular commodity bulk and a covering system as needed for weather protection;
• b. a uniquely designed and operated conveying system capable of moving the grain into storage at the base and elevating the bulk to fill the entire structure to a desired depth;
• and
• c. the same conveying means capable of removing all of the bulk product that freely flows by gravity to a central unload receiving point of the conveying system.
