Abstract

A roller support for draper belt supporting rollers of a harvester header may include a base, a first post extending from the base in a direction to support a first roller, a second post extending from the base in the direction to support a second roller, an arm extending from the base in the direction between the first post and the second post and a wear structure supported by and immovable relative to the arm. The wear structure may have a wear surface facing downwardly.

First claim

What is claimed is:

1. A harvester header comprising:
a first draper belt;
a first roller about which the first draper belt wraps;
a second draper belt;
a second roller about which the second draper belt wraps;
a float arm;
a first wear structure removably mounted to the float arm and providing a first wear surface facing upwardly;
a roller support supporting the first roller and the second roller, the roller support comprising:
a base;
an arm extending from the base towards the float arm; and
a second wear structure supported by and immovable relative to the arm, the second wear structure having a second wear surface facing downwardly, the second wear surface being in abutting contact with and slidable relative to the first wear surface.

2. The harvester header of claim 1 , wherein the second wear structure and the arm are integrally formed as a single unitary body.

3. The harvester header of claim 2 , wherein the arm and the base are integrally formed as a single unitary body.

4. The harvester header of claim 3 , wherein the roller support further comprises:
a first post extending from the base towards the float arm on a first side of the arm, the first post supporting the first roller; and
a second post extending from the base towards the float arm on a second side of the arm, opposite the first side, the second post supporting the second roller.

5. The harvester header of claim 4 , wherein the first post and the second post are integrally formed as a single unitary body with the base.

6. The harvester header of claim 5 , wherein the first wear structure is cantilevered from one side of the float arm.

7. The harvester header of claim 5 , wherein the first wear surface comprises iron boride Fe 2 B.

8. The harvester header of claim 7 , wherein the second wear surface comprises a chrome oxide spray coating.

9. The harvester header of claim 1 , wherein the roller support further comprises:
a first post extending from the base towards the float arm on a first side of the arm, the first post supporting the first roller; and
a second post extending from the base towards the float arm on a second side of the arm, opposite the first side, the second post supporting the second roller.

10. The harvester header of claim 9 , wherein the first post and the second post are integrally formed as a single unitary body with the base.

11. The harvester header of claim 1 , wherein the first wear structure is cantilevered from one side of the float arm.

12. The harvester header of claim 1 , wherein the first wear surface comprises iron boride Fe 2 B.

13. The harvester header of claim 12 , wherein the second wear surface comprises a chrome oxide coating.

14. The harvester header of claim 1 further comprising first and second support rods extending from the base.

15. A roller support for draper belt supporting rollers of a harvester header, the roller support comprising:
a base;
a first post extending from the base in a direction to support a first roller;
a second post extending from the base in the direction to support a second roller, wherein the first post and the second post are integrally formed as a single unitary body with the base;
an arm extending from the base in the direction between the first post and the second post; and
a wear structure supported by and immovable relative to the arm, the wear structure having a wear surface facing downwardly.

16. The roller support of claim 15 , wherein the wear structure and the arm are integrally formed as a single unitary body.

17. The roller support of claim 15 , wherein the wear surface comprises a chrome oxide coating.

18. A method for supporting a draper belt of a harvester header, the method comprising:
supporting a first draper belt and a second draper belt with the first roller and a second roller, respectively;
supporting the first and second rollers with a roller support comprising:
a base;
a first post extending from the base in a direction to support the first roller;
a second post extending from the base in the direction to support the second roller;
an arm extending from the base in the direction between the first post and the second post; and
a wear structure supported by and immovable relative to the arm, the wear structure having a wear surface facing downwardly and slidably abutting a wear structure supported by a float arm of the harvester header.

19. The method of claim 18 , wherein the wear surface comprises a chrome oxide coating and wherein the wear structure has a layer of iron boride Fe 2 B in abutment with the chrome oxide coating.
