ABSTRACT:
A sweep auger, mounted for rotation in a horizontal plane within a circular storage bin is comprised of two flights. The first flight has a constant diameter and a constant pitch. The second flight has the same constant diameter but a variable pitch so as to form a composite flight having sections of variable thickness longitudinally of the sweep auger. The sweep auger is capable of removing a uniform layer of grain and beans and the like from the bin floor during each complete revolution across the floor of the storage bin, and is adapted to handle a variety of material particle sizes.
