Abstract

An agricultural vehicle including a chassis and a header connected to the chassis. The header includes a frame, at least one crop divider connected to the frame and having a crop divider body with at least one opening therein, and at least one down crop gatherer rotatably mounted to the at least one crop divider and at least partially extending through the at least one opening of the crop divider body. The at least one down crop gatherer has a first rotational direction. The header also includes a drive unit rotatably mounted to the at least one crop divider and contacting the at least one down crop gatherer. The drive unit has a second rotational direction and is configured for contacting the field and driving the at least one down crop gatherer in its first rotational direction.

First claim

What is claimed is:

1. An agricultural vehicle, comprising:
a chassis; and
a header connected to the chassis and configured for traversing a field in a forward direction to harvest a crop material, said header including:
a frame;
at least one crop divider connected to the frame and having a crop divider body with at least one opening therein;
at least one down crop gatherer rotatably mounted to said at least one crop divider and at least partially extending through said at least one opening of the crop divider body, said at least one down crop gatherer having a first rotational direction, and said at least one down crop gatherer being in the form of at least one gathering wheel; and
a drive unit rotatably mounted to said at least one crop divider and contacting said at least one down crop gatherer, said drive unit having a second rotational direction and being configured for contacting the field and driving said at least one down crop gatherer in its first rotational direction.

2. The agricultural vehicle of claim 1 , wherein the drive unit includes at least one shaft rotatably coupled to said at least one crop divider and at least one drive wheel connected to the shaft.

3. The agricultural vehicle of claim 2 , wherein said at least one drive wheel respectively contacts the field and said at least one down crop gatherer as the header is moved in the forward direction such that said at least one drive wheel rotates in the second rotational direction and drives the down crop gatherer.

4. The agricultural vehicle of claim 3 , wherein said at least one gathering wheel is driven by said at least one drive wheel.

5. The agricultural vehicle of claim 4 , wherein said at least one gathering wheel includes a plurality of protuberances configured for contacting a down crop material.

6. The agricultural vehicle of claim 5 , wherein said plurality of protuberances are in the form of a plurality of flaps extending outwardly from said at last one gathering wheel.

7. The agricultural vehicle of claim 5 , wherein said plurality of protuberances are composed of at least one of a plastic material and a rubber material.

8. The agricultural vehicle of claim 1 , wherein said header further includes a gatherer shaft configured for rotatably mounting said at least one down crop gatherer to said at least one crop divider.

9. The agricultural vehicle of claim 1 , wherein said at least one down crop gatherer and said at least one drive unit rotate in opposite directions.

10. A header for an agricultural vehicle traversing a field in a forward direction to harvest a crop material, said header including:
a frame;
at least one crop divider connected to the frame and having a crop divider body with at least one opening therein;
at least one down crop gatherer rotatably mounted to said at least one crop divider and at least partially extending through said at least one opening of the crop divider body, said at least one down crop gatherer having a first rotational direction, and said at least one down crop gatherer being in the form of at least one gathering wheel; and
a drive unit rotatably mounted to said at least one crop divider and contacting said at least one down crop gatherer, said drive unit having a second rotational direction and being configured for contacting the field and driving said at least one down crop gatherer in its first rotational direction.

11. The header of claim 10 , wherein the drive unit includes at least one shaft rotatably coupled to said at least one crop divider and at least one drive wheel connected to the shaft.

12. The header of claim 11 , wherein said at least one drive wheel respectively contacts the field and said at least one down crop gatherer as the header is moved in the forward direction such that said at least one drive wheel rotates in the second rotational direction and drives the down crop gatherer.

13. The header of claim 12 , wherein said at least one gathering wheel is driven by said at least one drive wheel.

14. The header of claim 13 , wherein said at least one gathering wheel includes a plurality of protuberances configured for contacting a down crop material.

15. The header of claim 14 , wherein said plurality of protuberances are in the form of a plurality of flaps extending outwardly from said at last one gathering wheel.

16. The header of claim 14 , wherein said plurality of protuberances are composed of at least one of a plastic material and a rubber material.

17. The header of claim 10 , wherein said header further includes a gatherer shaft configured for rotatably mounting said at least one down crop gatherer to said at least one crop divider.

18. The header of claim 10 , wherein said at least one down crop gatherer and said at least one drive unit rotate in opposite directions.

19. A method for operating an agricultural vehicle, comprising the steps of:
providing a header for traversing a field, said header including a frame, at least one crop divider connected to the frame and having a crop divider body with at least one opening therein, at least one down crop gatherer rotatably mounted to said at least one crop divider and at least partially extending through said at least one opening of the crop divider body, said at least one down crop gatherer having a first rotational direction, and said at least one down crop gatherer being in the form of at least one gathering wheel, and a drive unit rotatably mounted to said at least one crop divider and contacting said at least one down crop gatherer, said drive unit having a second rotational direction and being configured for contacting the field and driving said at least one down crop gatherer in its first rotational direction;
rotating the drive unit in the second rotational direction by moving the header in a forward direction;
driving said at least one down crop gatherer by translating a rotational movement of the drive unit to rotate said at least one down crop gatherer in the first rotational direction; and
gathering a down crop material from said at least one crop divider toward a rear of the header by said down crop gatherer.

20. The method of claim 19 , wherein the drive unit includes at least one shaft rotatably coupled to said at least one crop divider and at least one drive wheel connected to the shaft, and said at least one gathering wheel contacts said at least one drive wheel.
