Bin sweep auger unplugging system
A bin sweep auger unplugging system for unplugging a central unloading sump in a storage bin. The bin sweep auger unplugging system generally includes an auger having a driven shaft with auger fighting, a drive unit having a drive shaft, and a clutch connected between the drive shaft and the driven shaft. The clutch selectively transfers the rotation of the drive shaft to the driven shaft of the auger. The drive shaft includes a clump breakup component that breaks up the clump of granular material above the unloading sump when the drive shaft is rotated. The clutch is disengaged when breaking up a clump of granular material to prevent the rotation of the auger.

6. The bin sweep auger of claim 5 , wherein the projections each extend outwardly and radially from the drive shaft.
7. The bin sweep auger of claim 5 , wherein the projections are each comprised of teeth, tines or straight shafts.
8. The bin sweep auger of claim 1 , wherein the clutch is comprised of a one-way clutch.
9. The bin sweep auger of claim 1 , wherein the clutch is concentrically positioned with respect to the drive shaft and the driven shaft.
10. The bin sweep auger of claim 1 , wherein the clutch is comprised of a manual clutch.
11. The bin sweep auger of claim 1 , wherein the clutch is comprised of the outer end of the drive shaft being rotatably connected to the inner end of the driven shaft and a fastener removably extending through an aperture within the drive shaft and the driven shaft.
12. The bin sweep auger of claim 1 , wherein the clutch is remote controlled to selectively engage or disengage.
13. The bin sweep auger of claim 1 , wherein the clutch is mechanically actuated by an actuator to selectively engage or disengage.
14. The bin sweep auger of claim 1 , wherein the drive unit is comprised of a reversible motor that rotates the drive shaft in the first direction or the second direction.
15. The bin sweep auger of claim 1 , wherein the drive unit is comprised of a motor connected to at least one gearbox that rotates the drive shaft in the first direction or the second direction.
16. The bin sweep auger of claim 15 , wherein the at least one gearbox is comprised of a first gearbox connected to an unloading conveyor and a second gearbox connected to the first gearbox by a connecting shaft, wherein the drive shaft extends from the second gearbox.
17. The bin sweep auger of claim 1 , wherein the drive shaft is positioned above an unloading sump in a storage bin.
18. A method of using the bin sweep auger of claim 1 , comprising the step of rotating the drive shaft in the second direction by the drive unit with the clutch disengaged to break up a grain clump by the rotation of the drive shaft and the first fighting in the second direction without rotating the driven shaft.
19. A bin sweep auger, comprising:
a backboard;
a drive shaft having an inner end and an outer end;
wherein the drive shaft is positioned above an unloading sump in a storage bin;
a first fighting extending from the drive shaft;
a drive unit connected to the inner end of the drive shaft;
a driven shaft having an inner end and an outer end, wherein the driven shaft is rotatably connected to the backboard;
a second flighting extending from the driven shaft; and
a clutch connected between the drive shaft and the driven shaft;
wherein the clutch is configured for engaging or disengaging to selectively lock or unlock the rotation of the drive shaft with the driven shaft;
wherein the clutch is engaged when the drive shaft is rotated in the first direction so that the drive shaft rotates the driven shaft in the first direction, and wherein the clutch is disengaged when the drive shaft is rotated in a second direction so that the drive shaft does not rotate the driven shaft in the second direction;
wherein the first flighting and the second flighting are adapted to unload grain from a grain bin when rotated in the first direction;
wherein the first flighting breaks up a grain clump when rotated in the second direction;
