Abstract

A belt guide for a baler having a bale forming chamber with at least one belt to form a bale of crop material includes a guide. The guide includes a guide protrusion that extends inwardly toward the bale forming chamber proximate an edge of the at least one belt. The belt guide is coupled to the baler external to the bale forming chamber.

First claim

What is claimed is:

1. A belt guide for a baler having a bale forming chamber with at least one belt to form a bale of crop material and having a wrap feed system, the belt guide comprising:
a guide body including a belt- or wrap material-contacting guide surface and a guide including a guide protrusion that extends through an opening in the guide body inwardly toward the bale forming chamber proximate an edge of the at least one belt;
wherein the belt guide is coupled to the baler external to the bale forming chamber; and
wherein, when the wrap feed system is supplying wrap material into the bale forming chamber, the belt guide is configured so that the wrap material extends over the guide protrusion between the guide protrusion and the edge of the at least one belt.

2. The belt guide of claim 1 , wherein the guide is coupled to the guide body.

3. The belt guide of claim 2 , wherein the guide protrusion extends a distance above the guide surface.

4. The belt guide of claim 2 , wherein the guide surface is oblique to a surface of the at least one belt.

5. The belt guide of claim 4 , wherein a clearance is defined between the at least one belt and the guide surface.

6. The belt guide of claim 2 , further comprising a hinge coupled to the guide at a first end, the hinge having a second end that cooperates with the guide and the guide body to receive a portion of the baler to couple the belt guide to the baler.

7. The belt guide of claim 6 , wherein the guide body includes a coupling portion, and the hinge includes a mounting portion at the second end that cooperates with the coupling portion to couple the belt guide to the portion of the baler.

8. The belt guide of claim 7 , wherein the portion of the baler is a cross-member associated with the wrap feed system.

9. The belt guide of claim 2 , wherein the guide surface comprises two guide surfaces and the guide has opposed sides, with one of the guide surfaces on each side of the guide.

10. A baler comprising:
a bale forming chamber having at least one belt to form a bale of crop material;
a wrap feed system; and
a belt guide coupled to the baler so as to be external to the bale forming chamber, the belt guide including a guide body including a belt- or wrap material-contacting guide surface and a guide with a guide protrusion that extends through an opening in the guide body inwardly toward the bale forming chamber proximate an edge of the at least one belt;
wherein, when the wrap feed system is supplying wrap material into the bale forming chamber, the wrap material extends over the guide protrusion between the guide protrusion and the edge of the at least one belt.

11. The baler of claim 10 , wherein the guide is coupled to the guide body.

12. The baler of claim 11 , wherein the guide protrusion extends a distance above the guide surface.

13. The baler of claim 11 , wherein the guide surface is oblique to an exterior surface of the at least one belt.

14. The baler of claim 13 , wherein a clearance is defined between the exterior surface of the at least one belt and the guide surface.

15. The baler of claim 11 , wherein the belt guide further comprises a hinge coupled to the guide at a first end, the hinge having a second end that cooperates with the guide and the guide body to receive a portion of the baler to couple the belt guide to the baler and the portion of the baler is a cross-member associated with the wrap feed system.

16. The baler of claim 11 , wherein the guide surface comprises two guide surfaces and the guide has opposed sides, with one of the guide surfaces on each side of the guide.

17. The baler of claim 11 , wherein the at least one belt is supported on at least one belt support member, and the belt guide is coupled to the portion of the baler such that an end of the guide is adjacent to the at least one belt support member.

18. A baler comprising:
a bale forming chamber having a plurality of belts to form a bale of crop material, the plurality of belts supported on at least one belt support member, with a gap defined between adjacent belts of the plurality of belts;
a wrap feed system; and
a belt guide coupled to the baler, the belt guide coupled to the baler external to the bale forming chamber, the belt guide including:
a guide including a guide protrusion that extends into one of the gaps defined between adjacent belts of the plurality of belts and inward toward the bale forming chamber, the guide proximate edges of the respective adjacent belts of the plurality of belts; and
a guide body having a belt- or wrap material-contacting guide surface positioned proximate the respective adjacent belts of the plurality of belts opposite the bale forming chamber, the guide protrusion extends through an opening in the guide body a distance above the guide surface;
wherein, when the wrap feed system is supplying wrap material into the bale forming chamber, the wrap material extends over the guide surface and extends over the guide protrusion within the gap.

19. The baler of claim 18 , wherein a clearance is defined between the exterior surface each of the respective adjacent belts of the plurality of belts and the guide surface.

20. The baler of claim 18 , wherein the guide surface comprises two guide surfaces and the guide has opposed sides, with one of the guide surfaces coupled to each side of the guide.
