Abstract

An elevator assembly for a harvester may include an elevator housing and an elevator extending within the elevator housing between a proximal end and a distal end. As such, the elevator may be configured to carry harvested crops between its proximal and distal ends. Furthermore, the elevator assembly may include a storage hopper extending from the elevator housing at a location adjacent to the distal end of the elevator. The storage hopper may include a conveyor extending within the storage hopper between a first end and a second end, with the conveyor configured to carry the harvested crops between its first and second ends towards a discharge opening of the storage hopper.

Claims (29)

1. A harvester, comprising:

a chopper assembly that processes harvested crops;

an elevator extending between a proximal end and a distal end, the elevator positioned downstream of the chopper assembly such that the harvested crops processed by the chopper assembly are received by the elevator at the proximal end of the elevator, the elevator carries the harvested crops between its proximal and distal ends;

a conveyor that receives the harvested crops from the distal end of the elevator, the conveyor including a first end closest to the distal end of the elevator and a second end further away from the distal end of the elevator, the conveyor including a conveyor belt that travels in an endless loop to carry the harvested crops received from the elevator between its first and second ends to allow the harvested crops to be discharged from the second end of the conveyor; and

an extractor positioned relative to the conveyor, the extractor extracts debris from the harvested crops.

2. The harvester of claim 1 , wherein the extractor is positioned vertically above the conveyor.

3. The harvester of claim 1 , wherein the extractor is positioned vertically above both the elevator and the conveyor.

4. The harvester of claim 1 , wherein the extractor is configured to extract debris from the harvested crops expelled from the distal end of the elevator.

5. The harvester of claim 1 , wherein the conveyor is positioned vertically below the distal end of the elevator.

6. The harvester of claim 5 , wherein the conveyor is positioned vertically below the distal end of the elevator and vertically above the proximal end of the elevator.

7. The harvester of claim 1 , wherein the harvested crops fall from the distal end of the elevator onto the conveyor.

8. The harvester of claim 1 , wherein an operating speed of the conveyor is adjustable.

9. The harvester of claim 1 , wherein the extractor comprises an extractor fan configured to generate a suction force for extracting the debris from the harvested materials.

10. The harvester of claim 1 , wherein the extractor comprises a secondary extractor of the harvester.

11. The harvester of claim 10 , further comprising a primary extractor positioned closer to the proximal end of the elevator than the secondary extractor.

12. The harvester of claim 1 , wherein the harvested crops discharged from the second end of the conveyor are configured to be dispelled from the harvester into an external receiver.

13. A harvester, comprising:

an elevator extending between a proximal end and a distal end, the elevator configured to receive harvested crops at its proximal end and carry the harvested crops from its proximal end to its distal end;

a conveyor configured to receive the harvested crops from the distal end of the elevator, the conveyor including a first end closest to the distal end of the elevator and a second end further away from the distal end of the elevator, the conveyor including a conveyor belt that travels in an endless loop to carry the harvested crops received from the elevator between its first and second ends to allow the harvested crops to be discharged from the second end of the conveyor;

a primary extractor configured to extract debris from the harvested crops being directed towards the proximal end of the elevator; and

a secondary extractor configured to extract debris from the harvested crops expelled from the distal end of the elevator.

14. The harvester of claim 13 , wherein the conveyer is positioned vertically below the secondary extractor.

15. The harvester of claim 13 , wherein the conveyor is positioned vertically below the distal end of the elevator.

16. The harvester of claim 15 , wherein the conveyor is positioned vertically below the distal end of the elevator and vertically above the proximal end of the elevator.

17. The harvester of claim 13 , wherein the harvested crops fall from the distal end of the elevator onto the conveyor.

18. The harvester of claim 13 , wherein an operating speed of the conveyor is adjustable.

19. The harvester of claim 13 , wherein the conveyor comprises a conveyor belt that travels in an endless loop between the first and second ends of the conveyor.

20. The harvester of claim 13 , wherein the extractor comprises an extractor fan configured to generate a suction force for extracting the debris from the harvested materials.

21. The harvester of claim 13 , wherein the harvested crops discharged from the second end of the conveyor are configured to be dispelled from the harvester into an external receiver.
