Bin sweep auger unplugging system

A bin sweep auger for breaking up a clump of granular material above an unloading sump in a storage bin, comprising:

• a drive shaft having an inner end and an outer end, wherein the drive shaft is positioned above the unloading sump in the storage bin;
• a drive unit connected to the inner end of the drive shaft;
• an auger having a driven shaft, an inner end, an outer end and an auger flighting, wherein a longitudinal axis of the drive shaft and a longitudinal axis of the driven shaft are concentric;
• wherein a length of the drive shaft is less than a length of the auger;
• a manual clutch comprising a first fastener and a second fastener for selectively connecting the inner end of the driven shaft to the outer end of the drive shaft to selectively lock or unlock rotation of the drive shaft with the driven shaft;
• and
• a flighting positioned about and extending from the drive shaft, wherein the flighting breaks up the clump of granular material when the drive shaft is rotated;
• wherein the drive shaft includes a first aperture and a second aperture near the outer end of the drive shaft, wherein the driven shaft includes a first aperture and a second aperture near the inner end of the driven shaft corresponding respectively to the first aperture and the second aperture of the drive shaft, wherein the manual clutch is engaged when the first fastener extends through the first aperture of the drive shaft and the first aperture of the driven shaft and when the second fastener extends through the second aperture of the drive shaft and the second aperture of the driven shaft, and wherein the manual clutch is disengaged when the first fastener and the second fastener are removed from the first aperture and the second aperture respectively of the drive shaft and the first aperture and the second aperture respectively of the driven shaft whereby the drive shaft rotates freely from the driven shaft thereby not rotating the auger.
