Patent ID: 7350964

Claim:
A device for circulating a grain product from a lower to an upper storage region, comprising: a feed screw having a screw axis and configured for immersion in the grain product, and a drive unit driving the feed screw, both of which are connected via a coupling unit, wherein the drive unit is non-rotatably connected with a support body which has a lower support surface that is inclined relative to the axis of the feed screw, the support body having a surface area capable of supporting the device on the surface of the grain product during operation of the feed screw and including at least one blocking plate oriented parallel to the screw axis and extending in a radial direction with respect to the screw axis, said blocking plate immersed in the grain product, wherein the blocking plate has a surface area capable of withstanding the peripheral forces of the rotating feed screw, wherein the feed screw has a length greater than an immersion depth of the blocking plate, and wherein the feed screw is sized so as to enable the grain product to be circulated from a lowermost to an uppermost storage region.
