主权项

1. A method for sweeping a storage bin, the method comprising:
rotating a first auger about a first longitudinal axis, wherein the first auger is supported by a first section frame of a bin sweep; rotating a second auger about a second longitudinal axis, wherein the second auger is supported by a second section frame of the bin sweep, the second section frame being operably engaged with the first section frame; moving the first section frame relative to a central support framework of the storage bin to cover a first footprint of the storage bin; extending the second section frame relative to the first section frame substantially along the second longitudinal axis, wherein the second section frame slideably moves along only a single side of the first section frame, and wherein a roller located on one of the first section frame and second section frame engages and rolls on a guide sleeve located on the other of the first section frame and second section frame; and moving the first section frame relative to the central support framework to sweep a second footprint of the storage bin after extending the second section frame, the second footprint having a greater area than the first footprint for a given distance of movement of the first section frame relative to the central support framework.
