Agricultural elevator supplied by multiple cross augers
An agricultural harvester includes a chassis, a cleaning system carried by the chassis, and a crop material elevator for receiving crop material that has passed through the cleaning system. The crop material elevator has a top-most end, a bottom-most end, a first inlet between the top-most end and the bottom-most end, and a second inlet between the top-most end and the first inlet. The agricultural harvester also includes an auger system for supplying crop material from the cleaning system to the crop material elevator. The auger system includes a first auger defining an auger axis for supplying crop material to the first inlet, a second auger defining a second auger axis, and a crop material conveyor for supplying crop material from the second auger to the second inlet.
1. An agricultural harvester, comprising:
a chassis;
a cleaning system carried by the chassis;
a crop material elevator for receiving crop material that has passed through the cleaning system, the crop material elevator comprising:
a top-most end;
a bottom-most end opposite the top-most end;
a first inlet between the top-most end and the bottom-most end; and
a second inlet between the top-most end and the first inlet; and
an auger system for supplying crop material from the cleaning system to the crop material elevator, the auger system comprising:
a first auger defining an auger axis for supplying crop material to the first inlet;
a second auger defining a second auger axis; and
a crop material conveyor for supplying crop material from the second auger to the second inlet;
wherein the second auger is located above the second inlet.
2. The agricultural harvester of claim 1 , wherein the crop material elevator comprises an upper axle in proximity to the top-most end and a lower axle in proximity to the bottom-most end.
3. The agricultural harvester of claim 2 , wherein the first inlet is adjacent the lower axle, and the second inlet is between the lower axle and the upper axle.
4. The agricultural harvester of claim 2 , wherein the lower axle defines an axle axis that is generally transverse to the auger axis.
5. The agricultural harvester of claim 2 , wherein the lower axle defines an axle axis that is aligned with the second inlet.
6. The agricultural harvester of claim 1 , wherein the crop material elevator comprises a sloping surface descending from the second inlet toward the bottom-most end of the crop material elevator.
7. The agricultural harvester of claim 6 , wherein the crop material conveyor comprises a sloped surface directed toward the second inlet.
8. The agricultural harvester of claim 7 , wherein the crop material conveyor comprises a curved wall for directing crop material toward the sloped surface.
9. The agricultural harvester of claim 7 , wherein the sloping surface and sloped surface are sloped at an angle α.
10. The agricultural harvester of claim 9 , wherein angle α is greater than 25 degrees.
11. The agricultural harvester of claim 10 , wherein angle α is between 30 and 55 degrees.
12. An agricultural harvester, comprising:
a chassis;
a cleaning system carried by the chassis;
a crop material elevator for receiving crop material that has passed through the cleaning system, the crop material elevator comprising:
a top-most end;
a bottom-most end opposite the top-most end;
a first inlet between the top-most end and the bottom-most end; and
a second inlet between the top-most end and the first inlet; and
an auger system for supplying crop material from the cleaning system to the crop material elevator, the auger system comprising:
a first auger defining an auger axis for supplying crop material to the first inlet;
a second auger defining a second auger axis; and
a crop material conveyor for supplying crop material from the second auger to the second inlet, wherein the crop material conveyor comprises a cross auger.
13. The agricultural harvester of claim 1 , wherein the crop material elevator comprises a loop and a plurality of paddles connected to the loop.
14. The agricultural harvester of claim 13 , wherein the loop is driven by a sprocket.
15. The agricultural harvester of claim 1 , wherein the auger axis is generally parallel to the second auger axis.
16. The agricultural harvester of claim 1 , wherein the bottom-most end of the crop material elevator is rounded.
17. The agricultural harvester of claim 1 , wherein the crop material conveyor is configured to supply crop material from the second auger to the second inlet transverse to the second auger axis.
