Abstract

A belt and coupler arrangement for a feederhouse feed conveyor of an agricultural harvester includes an elongate belt having an elongate web (154) with a first end (102) and a second end (104), wherein the first end (102) and the second end (104) are thicker than the elongate web; and a coupler (100) having a first elongate recess to receive and enclose the first end (102), and a second elongate recess to receive and enclose the second end (104).

First claim

The invention claimed is:

1. A belt and coupler arrangement for a feederhouse feed conveyor of an agricultural harvester, the arrangement comprising:
an elongate belt having an elongate web with a first end and a second end, wherein the first end and the second end are thicker than the elongate web; and
a coupler having a first elongate recess to receive and enclose the first end, and a second elongate recess to receive and enclose the second end;
wherein the first elongate recess has a first elongate gap defined by first and second lips that are opposed and through which the elongate web extends;
wherein the second elongate recess has a second elongate gap defined by third and fourth lips that are opposed and through which the elongate web extends; and
wherein the coupler further comprises:
a first plate having a first abutment surface and the first and third lips,
a second plate having a second abutment surface and the second and fourth lips,
at least one threaded fastener fixing the first plate and the second plate together and forcibly abutting the first and second abutment surfaces together when the at least one fastener is torqued,
wherein the first and second abutment surfaces when forced into an abutting relationship establish predetermined volumes of the first and second elongate recesses and predetermined widths of the first and second elongate gaps, and
wherein the first abutment surface is disposed on a first ridge extending downward from an underside of the first plate, and wherein the second abutment surface is disposed on a second ridge that extends upward from an upper side of the second plate.

2. The belt and coupler arrangement of claim 1 , wherein the first end defines a first upper lobe that extends upward above the web and a first lower lobe that extends downward below the web.

3. The belt and coupler arrangement of claim 2 , wherein the second end defines a second upper lobe that extends upward above the web and a second lower lobe that extends downward below the web.

4. The belt and coupler arrangement of claim 3 , wherein the first upper lobe and the second upper lobe are disposed in a first central recess, and wherein the first lower lobe and the second lower lobe are disposed in a second central recess.

5. The belt and coupler arrangement of claim 1 , wherein the first and second abutment surfaces are disposed between the first end and the second end.

6. The belt and coupler arrangement of claim 1 , wherein the at least one fastener extends through a first gap in the first and second abutment surfaces.

7. The belt and coupler arrangement of claim 1 , wherein the web comprises a first fiber layer extending substantially the entire length of the web, and wherein the first end comprises a first retaining rod wrapped by the first fiber layer.

8. The belt and coupler arrangement of claim 7 , wherein the web comprises a second fiber layer extending substantially the entire length of the web, and wherein the first end comprises a second retaining rod wrapped by the second fiber layer.

9. The belt and coupler arrangement of claim 8 , wherein the first retaining rod and the second retaining rod are disposed inside the first elongate recess.

10. The belt and coupler arrangement of claim 9 , wherein the first retaining rod and the second retaining rod have a height greater than the first elongate gap.

11. The belt and coupler arrangement of claim 10 , wherein the first retaining rod and the second retaining rod abut opposing side of the first elongate recess to prevent the first end from being pulled out of the first elongate recess.

12. The belt and coupler arrangement of claim 2 , wherein the first end wall covers a first end of the first and second upper lobes, and a first end of the first and second lower lobes.

13. The belt and coupler arrangement of claim 12 , wherein a second end wall covers a second end of the first and second upper lobes, and a second end of the first and second lower lobes.

14. The belt and coupler arrangement of claim 13 , wherein the first end wall and the second end wall extend from the second plate, and abut the first plate.
