Abstract

A crop dividing device for an agricultural header including a hood and a divider connected to the hood. The divider includes a base member pivotally connected to the hood. The base member includes a receiving section. The divider also includes an ear dam member receivable in the receiving section. The ear dam member is positionable in between a first position for increasing an overall slope of the divider and a second position for decreasing the overall slope of the divider. The ear dam member is connected to the receiving section in the first position, and the ear dam member is connected to one of the hood and base member in the second position.

First claim

The invention claimed is:

1. A crop dividing device for an agricultural header with a frame, comprising:
a hood configured for connecting to the frame of the agricultural header; and
a divider connected to the hood and comprising:
a base member pivotally connected to the hood and comprising a receiving section; and
an ear dam member receivable in the receiving section, the ear dam member is positionable in between a first position for increasing an overall slope of the divider and a second position for decreasing the overall slope of the divider, the ear dam member is connected to the receiving section in the first position, and the ear dam member is connected to one of the hood and base member in the second position,
wherein the ear dam member comprises a first side defining a first ear dam slope and a second side opposite the first side and defining a second ear dam slope which is less steep than the first ear dam slope, and
wherein the ear dam member is connected to the receiving section in the first position and the second position such that the first side faces upwardly and extends above the base member in the first position and the second side faces upwardly in the second position.

2. The crop dividing device of claim 1 , wherein the first ear dam slope increases the overall slope of the divider.

3. The crop dividing device of claim 2 , wherein the second position is a stored position of the ear dam member, and the ear dam member in the stored position is stored in one of the hood and base member such that the ear dam member does not extend above the base member, which decreases the overall slope of the divider for gathering a down crop material.

4. The crop dividing device of claim 1 , wherein the receiving section of the base member is one of an indent and an opening, and the ear dam member is detachably connected to the receiving section in the first position.

5. The crop dividing device of claim 1 , wherein the ear dam member comprises at least one protrusion configured for engaging with the receiving section of the base member.

6. The crop dividing device of claim 5 , wherein the base member further comprises at least one track, and the at least one protrusion of the ear dam member engages with the at least one track in the first position.

7. The crop dividing device of claim 6 , wherein the base member further comprises a shell body, an upper track adjacent to the receiving section, and a lower track inside the shell body, and the at least one protrusion of the ear dam member engages with the upper track in the first position and with the lower track in the second position such that the ear dam member does not contact a crop material and is stored within the base member in the second position.

8. The crop dividing device of claim 6 , wherein the receiving section comprises at least one locking feature, and the ear dam member further comprises at least one corresponding locking feature which contacts the at least one locking feature of the receiving section in the first position.

9. The crop dividing device of claim 1 , wherein the ear dam member contacts a crop material in both of the first position and second position.

10. A header connectable to an agricultural vehicle, comprising:
a frame; and
at least one crop dividing device connected to the frame, the at least one crop dividing device comprising:
a hood connected to the frame; and
a divider connected to the hood and comprising:
a base member pivotally connected to the hood and comprising a receiving section; and
an ear dam member receivable in the receiving section, the ear dam member is positionable in between a first position for increasing an overall slope of the divider and a second position for decreasing the overall slope of the divider, the ear dam member is connected to the receiving section in the first position, and the ear dam member is connected to one of the hood and base member in the second position,
wherein the ear dam member comprises a first side defining a first ear dam slope and a second side opposite the first side and defining a second ear dam slope which is less steep than the first ear dam slope, and
wherein the ear dam member is connected to the receiving section in the first position and the second position such that the first side faces upwardly and extends above the base member in the first position and the second side faces upwardly in the second position.

11. The header of claim 10 , wherein first ear dam slope increases the overall slope of the divider.

12. The header of claim 11 , wherein the second position is a stored position of the ear dam member, and the ear dam member in the stored position is stored in one of the hood and base member such that the ear dam member does not extend above the base member, which decreases the overall slope of the divider for gathering a down crop material.

13. The header of claim 10 , wherein the receiving section of the base member is one of an indent and an opening, and the ear dam member is detachably connected to the receiving section in the first position.

14. The header of claim 10 , wherein the ear dam member comprises at least one protrusion configured for engaging with the receiving section of the base member.

15. The header of claim 14 , wherein the base member further comprises at least one track, and the at least one protrusion of the ear dam member engages with the at least one track in the first position.

16. The header of claim 15 , wherein the base member further comprises a shell body, an upper track adjacent to the receiving section, and a lower track inside the shell body, and the at least one protrusion of the ear dam member engages with the upper track in the first position and with the lower track in the second position such that the ear dam member does not contact a crop material and is stored within the base member in the second position.

17. The header of claim 15 , wherein the receiving section comprises at least one locking feature, and the ear dam member further comprises at least one corresponding locking feature which contacts the at least one locking feature of the receiving section in the first position.

18. The header of claim 10 , wherein the ear dam member contacts a crop material in both of the first position and second position.

19. A method for selectively varying a crop saving capability of a header, comprising:
positioning an ear dam member in a first position in a crop dividing device for the header, the crop dividing device comprising a hood configured for connecting to the header and a divider connected to the hood, the divider comprising a base member pivotally connected to the hood and comprising a receiving section, the ear dam member comprising a first side defining a first ear dam slope and a second side, the positioning for increasing an overall slope of the divider by connecting the ear dam member to the receiving section such that the first side of the ear dam member faces upwardly and extends above the base member to increase an overall slope of the divider; and
positioning the ear dam member in a second position for decreasing the overall slope of the divider by connecting the ear dam member to one of the hood and base member, the second side of the ear dame facing upwardly when the ear dam member is in the second position.

20. The method of claim 19 , wherein the second position is a stored position of the ear dam member, and the ear dam member in the stored position is stored in one of the hood and base member such that
