ABSTRACT:
Circulator grain bins commonly comprise upright sidewall means customarily circularly surrounding the bin vertical-axis and also a substantially horizontal floor for supporting a lofty depth of grain thereupon; there is a substantially horizontal elongate sweep auger located immediately above the floor and henced submerged at the bottom of the grain pile, the sweep auger radiating lengthily outwardly from and angularly rotatable about the bin vertical-axis. Each of at least two consecutive medial helical flights for the sweep auger is provided with separate distinct cogs extending radially externally from the flighting helical edge whereby said arrayed distinct cogs at their curved free-edges define a segmented spiroid wheel rim submerged within the grain. A substantially horizontal annular roadway located along the bin floor between the bin sidewall and vertical-axis abuttably underlies the submerged spiroid rim whereby angular rotation of the axially revolving sweep auger is enhanced and improved to an unusually reliable condition.
