Abstract

An agricultural harvester includes a chassis, a header for cutting and gathering crop material, the header being carried by the chassis, and an auger. The auger moves the cut crop material toward a central area of the header. The auger is rotatably carried by the header. The auger has a plurality of auger sections. The auger includes an auger crankshaft and a hingeable coupling for coupling two of the auger sections to each other. The hingeable coupling allows the auger sections to rotate about differing axes. The hingeable coupling has an internal opening. The auger crankshaft provides positional timing to auger fingers. The auger crankshaft passing through the internal opening.

First claim

The invention claimed is:

1. An agricultural harvester, comprising:
a chassis;
a header for cutting and gathering crop material, the header configured for attachment to the chassis; and
an auger for moving the cut crop material, the auger being rotatably carried by the header, the auger having a plurality of auger sections;
wherein the auger comprises:
a hingeable coupling for coupling two of the auger sections to each other, the hingeable coupling allowing the auger sections to rotate about differing axes, the hingeable coupling having an internal opening; and
an auger crankshaft for providing positional timing to auger fingers, the auger crankshaft passing through the internal opening of the hingeable coupling, the auger crankshaft not contacting the hingeable coupling.

2. The agricultural harvester of claim 1 , further comprising a hanger support affixed to the header, the hanger support configured to support and rotatably couple the auger to the header allowing the auger to rotate relative to the hanger support.

3. The agricultural harvester of claim 2 , wherein the hingeable coupling is not directly coupled to the hanger support.

4. The agricultural harvester of claim 2 , wherein the hingeable coupling is directly coupled to the hanger support.

5. The agricultural harvester of claim 1 , wherein the auger crankshaft comprises a hingeable coupling.

6. The agricultural harvester of claim 5 , wherein the hingeable coupling of the auger crankshaft is not collocated with the hingeable coupling of the auger sections.

7. The agricultural harvester of claim 5 , wherein the hingeable coupling of the auger crankshaft is located proximate to the hingeable coupling of the auger sections.

8. The agricultural harvester of claim 1 , wherein the opening has edges, the auger crankshaft does not contact the edges even when the hingeable coupling is fully flexed.

9. The agricultural harvester of claim 1 , wherein the auger crankshaft is not drivingly coupled to the auger.

10. The agricultural harvester of claim 1 , wherein the hingeable coupling is interior to the auger.

11. The agricultural harvester of claim 1 , further comprising a plurality of hingeable couplings for coupling adjacent sections of the auger together along a longitudinal length of the auger.

12. An auger assembly for use on an agricultural harvester having a header, the auger assembly comprising:
an auger rotatably carried by the header, the auger having a plurality of auger sections;
a hingeable coupling for coupling two of the auger sections to each other, the hingeable coupling having an internal opening; and
an auger crankshaft passing through the internal opening, the auger crankshaft not contacting the hingeable coupling.

13. The auger assembly of claim 12 , further comprising a hanger support affixed to the header, the hanger support being rotatably coupled to the auger.

14. The auger assembly of claim 13 , wherein the hingeable coupling is not directly coupled to the hanger support.

15. The auger assembly of claim 13 , wherein the hingeable coupling is directly coupled to the hanger support.

16. The auger assembly of claim 12 , wherein the auger crankshaft includes a hingeable coupling.

17. The auger assembly of claim 16 , wherein the hingeable coupling of the auger crankshaft is not collocated with the hingeable coupling of the auger.

18. The auger assembly of claim 16 , wherein the hingeable coupling of the auger crankshaft is located proximate to the hingeable coupling of the auger sections.

19. The auger assembly of claim 12 , wherein the opening has edges, the auger crankshaft not touching the edges even when the hingeable coupling is fully flexed.

20. The auger assembly of claim 12 , wherein the hingeable coupling is interior to the auger, the hingeable coupling allowing the auger sections to rotate about differing axes.
