Folding Auger Assembly Coupler

摘要

An agricultural combine including an agricultural harvester, a crop tank for harvested material, and an unloading auger assembly for unloading and discharging crop material. The auger assembly has inner and outer auger tubes pivotally connected to one another. The auger tubes pivot between a first position in which the auger tubes extend transversely and are coaxial and a second position in which the auger tubes form an angle. The auger tubes contain augers having first and second couplings at cooperating ends. The first coupling has two projections extending to cooperate with a single radial projection on the second coupling to provide improved engagement.

1. An unloading tubular auger assembly for an agricultural harvester, said auger assembly comprising first and second tubes each having a longitudinal axis and pivotally connected to one another;
first and second augers positioned longitudinally in said tubes for rotating to move crop material longitudinally upon rotation of said augers; first and second couplers selectively coupling said first and second augers when said auger tubes are pivoted to be coaxial, said first coupler including at least two projections extending toward said second coupler, said second coupler having a single projection for interacting with one of said at least two projections.
