Abstract

The subject disclosure provides a draper belt assembly for an agricultural harvester header that includes a draper belt and a zipper assembly along a length of the draper belt. The zipper assembly includes a first zipper track extending at a non-perpendicular angle from a fore end of a leading edge of the draper belt, a second zipper track complementary to the first zipper track extending at a second non-perpendicular angle from the fore end of a trailing edge of the draper belt, and a slider releasably connectable to the first zipper track and the second zipper track.

First claim

The invention claimed is:

1. A draper belt assembly for an agricultural harvester header comprising:
a draper belt; and
a zipper assembly along a length of the draper belt, the zipper assembly including:
a first zipper track extending at a first, constant non-perpendicular angle from a fore end to an aft end of a leading edge of the draper belt,
a second zipper track complementary to the first zipper track extending at a second, constant non-perpendicular angle from the fore end to the aft end of a trailing edge of the draper belt, and
a slider releasably connectable to the first zipper track and the second zipper track.

2. The draper belt assembly of claim 1 , further comprising a lock for releasably securing the zipper assembly in a fixed position.

3. The draper belt assembly of claim 1 , further comprising a seal covering an upper surface of the first and second zipper tracks.

4. The draper belt assembly of claim 3 , wherein the seal overlaps an outer surface of the draper belt to cover the first zipper track and the second zipper track upon engagement of the slider to the first zipper track and the second zipper track.

5. The draper belt assembly of claim 3 , wherein the seal provides a watertight seal covering the first zipper track and the second zipper track.

6. The draper belt assembly of claim 3 , wherein the seal includes a first seal portion coextensive with the first zipper track and a second seal portion coextensive with the second zipper track.

7. The draper belt assembly of claim 6 , wherein the first seal portion and second seal portion overlap upon engagement of the first and second zipper tracks.

8. The draper belt assembly of claim 3 , wherein the seal is of unitary construction with the zipper assembly.

9. The draper belt assembly of claim 3 , wherein the seal includes a plurality of seal segments.

10. The draper belt assembly of claim 1 , wherein the draper belt comprises:
an outer surface that includes a plurality of spaced apart lugs or ribs.

11. The draper belt assembly of claim 10 , wherein the zipper assembly has a lower profile than the plurality of spaced apart lugs or ribs.

12. The draper belt assembly of claim 1 , wherein a portion of the first zipper track and second zipper track are vulcanized to the draper belt during manufacture thereof.

13. The draper belt assembly of claim 1 , wherein the sum of the first non-perpendicular angle and the second non-perpendicular angle is about 180°.

14. A header of an agricultural harvester comprising the draper belt assembly of claim 1 .

15. The draper belt assembly of claim 3 , wherein the seal is flush against the draper belt.

16. The draper belt assembly of claim 3 , wherein the seal extends from the zipper assembly.

17. The draper belt assembly of claim 3 , wherein the seal is coextensive with the leading edge of the draper belt.

18. The draper belt assembly of claim 1 , further comprising a seal extending from a leading section of the draper belt and extending past the leading edge of the draper belt sufficiently to overlap the zipper assembly and a portion of a trailing section of the draper belt adjacent the trailing edge.

19. The draper belt assembly of claim 1 , further comprising:
a lock for releasably securing the zipper assembly in a fixed position; and
a unitary watertight seal coextensive with the first zipper track and overlapping an outer surface of the draper belt and covering an upper surface of the first and second zipper tracks upon engagement of the slider to the first zipper track and the second zipper track, and
wherein the draper belt includes a plurality of spaced apart lugs or ribs and the zipper assembly has a lower profile than the plurality of spaced apart lugs or ribs, and
wherein a portion of the first zipper track and second zipper track are vulcanized to the draper belt.

20. A draper belt assembly for an agricultural harvester header comprising:
a draper belt that includes:
a leading edge at a first, constant non-perpendicular angle from a fore end to an aft end of the draper belt, and
a trailing edge at a second, constant non-perpendicular angle from a fore end to an aft end of the draper belt;

a zipper assembly along a length of the draper belt, the zipper assembly including:
a first zipper track extending along the leading edge of the draper belt,
a second zipper track complementary to the first zipper track extending along the trailing edge of the draper belt, and
a slider releasably connectable to the first zipper track and the second zipper track; and

a seal extending from a leading section of the draper belt and extending past the leading edge of the draper belt sufficiently to overlap the zipper assembly and a portion of a trailing section of the draper belt adjacent the trailing edge.
