Auger bed with multiple augers in a single trough for a combine harvester

An agricultural harvester comprising:

• a cylindrical threshing rotor;
• at least two augers;
• and
• an auger bed positioned beneath the rotor for receiving grain or other material therefrom, the auger bed comprising a trough for accommodating the at least two augers, the trough comprising two side walls and a lower wall directly interconnecting and extending between the two side walls, wherein the at least two augers are positioned in the trough at a location above the lower wall and between the two side walls, and wherein the lower wall is positioned to extend beneath both of the at least two augers,
• wherein longitudinal axes of the at least two augers are positioned along a curve, wherein a central axis of the curve is either coincident with or adjacent to a longitudinal axis of the threshing rotor,
• wherein the lower wall, which directly interconnects and extends between the two side walls, extends along a second curve, wherein a central axis of the second curve is either coincident with or adjacent to a longitudinal axis of the threshing rotor.
