Abstract
A separating and cleaning mechanism for an agricultural combine may include: a return pan. The return pan includes a textured floor, two augers, and two motors coupled to the two augers, respectively, to selectively drive the motors in rotation independently. The textured floor may oscillate in a fore-and-aft direction to move grain toward the two augers.

A return pan for an agricultural combine for harvesting crops in an agricultural field and having a direction of travel through the field, wherein the return pan comprises:
- a textured floor configured to push grain toward an exit of the return pan when the return pan is oscillated in a fore-and-aft direction;
- a first auger and a second auger that extend across a forward edge of the textured floor generally perpendicular to the fore-and-aft direction;
- a first motor coupled to the first auger to drive the first auger in rotation;
- and
- a second motor coupled to the second auger to drive the second auger in rotation;
- wherein the first auger and the second auger are arranged to be selectively driven in opposite rotational directions and to be selectively driven in the same rotational direction.
A separating and cleaning mechanism for an agricultural combine comprising:
- a return pan comprising:
- a textured floor configured to push grain toward an exit of the return pan when the return pan is oscillated in a fore-and-aft direction,
- a first auger and a second auger that extend across a forward edge of the textured floor generally perpendicular to the fore-and-aft direction,
- a first motor coupled to the first auger to selectively drive the first auger in different rotational directions, a second motor coupled to the second auger to selectively drive the second auger different rotational directions;
- and wherein the selective rotation of the first and second augers are independent of each other.
A return pan for an agricultural combine for harvesting crops in an agricultural field and having a direction of travel through the field, wherein the return pan comprises:
- a textured floor configured to push grain toward an exit of the return pan when the return pan is oscillated in a fore-and-aft direction;
- a first auger and a second auger that extend across a forward edge of the textured floor generally perpendicular to the fore-and-aft direction;
- a first motor coupled to the first auger to drive the first auger in rotation;
- a second motor coupled to the second auger to drive the second auger in rotation;
- and
- a curved pan fixed to the forward edge of the textured floor and extending forward and downward therefrom.
