Abstract

A shield to prevent crop material from wrapping around the shaft of a rotary conveyor of a harvester, such as a baler, includes a body. The body is positioned between a stripper finger and a shaft of the rotary conveyor and has an end surface facing the shaft. A lug is positioned at the opposite end of the body from the end surface and is attached to the housing of the rotary conveyor. The body has opposite side surfaces positioned in spaced relation at a distance substantially equal to the width of the separation fingers of the rotary conveyor.

First claim

What is claimed is:

1. A shield mountable on a rotary conveyor and positionable between a stripper finger and a shaft thereof, said shield comprising:
a body having first and second ends oppositely disposed;
an end surface positioned at said first end of said body, said end surface being positionable in facing relation to said shaft;
a lug positioned at said second end of said body, said lug being attachable to said rotary conveyor for retention of said shield thereto;
first and second side surfaces positioned on opposite sides of said body and extending between said end surface and said lug, the shield configured for having an absence of a hinged connection with the stripper finger about an axis parallel with a longitudinal axis of the shaft.

2. The shield according to claim 1 , wherein said lug is positionable between said stripper finger and said rotary conveyor.

3. The shield according to claim 1 , wherein said end surface has a concave radius of curvature configured for facing said shaft.

4. The shield according to claim 1 , wherein said lug extends substantially perpendicularly to said end surface.

5. The shield according to claim 2 , wherein said lug defines at least one hole adapted to receive a locating pin extending from one of said stripper fingers or said portion of said rotary conveyor.

6. The shield according to claim 2 , wherein said lug defines at least one hole adapted to receive a fastener for attaching said body to said portion of said rotary conveyor.

7. The shield according to claim 1 , wherein said lug further comprises first and second skirts positioned in spaced relation on opposite sides of said lug, said first and second skirts extending transversely to said lug.

8. The shield according to claim 1 , wherein said first and second side surfaces are spaced apart from one another a distance that is substantially equal to a width of said stripper finger.

9. The shield according to claim 1 , wherein said first and second side surfaces have respective first and second edges configured for facing said stripper finger, said first and second edges each having a shape configured for matching to a shape of said stripper finger.

10. The shield according to claim 9 , wherein said shapes of said first and second edges comprise a convex curvature.

11. The shield according to claim 1 , wherein said first and second sides further comprise respective first and second ventral edges positionable in facing relation with an end of said stripper finger.

12. The shield according to claim 11 , wherein said first and second ventral edges have a shape configured for matching to a shape of said end of said stripper finger.

13. The shield according to claim 12 , wherein said shape of said first and second ventral edges comprises a concave curvature.

14. A rotary conveyor, said rotary conveyor comprising:
a housing;
a shaft mounted on said housing for rotation about a longitudinal axis of said shaft;
a plurality of tines mounted on said shaft in spaced relation to one another;
a plurality of stripper fingers mounted on said housing in spaced relation to one another, each said tine being positioned between two said stripper fingers;
at least one shield, said at least one shield being positioned between one of said stripper fingers and said shaft and having an absence of a hinged connection with any of said stripper fingers about an axis parallel with said longitudinal axis of said shaft, said at least one shield comprising:
a body having first and second ends oppositely disposed;
an end surface positioned at said first end of said body, said end surface facing said shaft;
a lug positioned at said second end of said body, said lug being attached to said housing;
first and second side surfaces positioned on opposite sides of said body and extending between said end surface and said lug.

15. The rotary conveyor according to claim 14 , wherein said lug is positioned between said one stripper finger and said housing.

16. The rotary conveyor according to claim 14 , wherein said end surface has a concave radius of curvature facing said shaft.

17. The rotary conveyor according to claim 14 , wherein said lug extends substantially perpendicularly to said end surface.

18. The rotary conveyor according to claim 15 , wherein said lug defines at least one hole adapted to receive a locating pin extending from said one stripper finger or said housing.

19. The rotary conveyor according to claim 15 , wherein said lug defines at least one hole adapted to receive a fastener for attaching said body to said housing.

20. The rotary conveyor according to claim 14 , wherein said lug further comprises first and second skirts positioned in spaced relation on opposite sides of said lug, said first and second skirts extending transversely to said lug.

21. The rotary conveyor according to claim 14 , wherein said first and second side surfaces are spaced apart from one another a distance that is substantially equal to a width of said one stripper finger.

22. The rotary conveyor according to claim 14 , wherein said first and second side surfaces have respective first and second edges facing said one stripper finger, said first and second edges each having a shape matched to a shape of said one stripper finger.

23. The rotary conveyor according to claim 22 , wherein said shapes of said first and second edges comprise a convex curvature.

24. The rotary conveyor according to claim 14 , wherein said first and second sides further comprise respective first and second ventral edges positioned in facing relation with an end of said one stripper finger.

25. The rotary conveyor according to claim 24 , wherein said first and second ventral edges have a shape matched to a shape of said end of said one stripper finger.

26. The rotary conveyor according to claim 25 , wherein said shape of said first and second ventral edges comprises a concave curvature.

27. The rotary conveyor according to claim 14 , further comprising a plurality of said shields, each said shield being positioned between a respective one of said stripper fingers and said shaft.

28. A harvester, said harvester comprising:
a rotary conveyor comprising:
a housing;
a shaft mounted on said housing for rotation about a longitudinal axis of said shaft;
a plurality of tines mounted on said shaft in spaced relation to one another;
a plurality of stripper fingers mounted on said housing in spaced relation to one another, each said tine being positioned between two said stripper fingers;
at least one shield, said at least one shield being positioned between one of said stripper fingers and said shaft and having an absence of a hinged connection with any of said stripper fingers about an axis parallel with said longitudinal axis of said shaft, said at least one shield comprising:
a body having first and second ends oppositely disposed;
an end surface positioned at said first end of said body, said end surface facing said shaft;
a lug positioned at said second end of said body, said lug being attached to said housing;
first and second side surfaces positioned on opposite sides of said body and extending between said end surface and said lug.

29. The harvester according to claim 28 , wherein said lug is positioned between said one stripper finger and said housing.

30. The harvester accor
