Sweep auger

In combination with a circular grain storage bin having a floor, an improved apparatus for moving granular material radially along the floor of the bin toward the center of the bin floor, said apparatus comprising:

• an elongated auger with a longitudinal axis to be disposed radially of such a bin above and proximate the floor thereof, said auger having a leading edge and a trailing edge, the auger having an inner end disposed at the center of said bin and an opposite distal end disposed radially outward of the center of the bin, said inner end of said auger being connected to a power means at the center of said bin for rotating said auger about its longitudinal axis, a support and drive wheel located proximate to the distal end of said auger for supporting said distal end of said auger on said floor and for advancing said auger around the central vertical axis of said bin, the improvement comprising:
• an elongated inclined panel mounted adjacent the trailing edge of the auger with an upper edge being rearward of a lower edge,
• adjustment means for raising or lowering the panel with respect to the bin floor to minimize the amount of granular material passing under the auger as it moves over the bin floor and to provide clearance for variations in the level of the bin floor;
• and
• a backboard extending along and behind the auger, the panel being adjustable mounted on the backboard.
