Abstract

A header for an agricultural vehicle includes: a header frame; at least two row dividers carried by the header frame and defining a gap therebetween; and a crop material saver disposed in the gap and including a pair of saver flaps, each of the saver flaps being positioned such that the saver flaps co-act as a one-way pass-through to allow crop material flow past the saver flaps in an admission direction and inhibit crop material flow past the saver flaps in an inhibited direction opposite the admission direction.

First claim

What is claimed is:

1. A header for an agricultural vehicle, comprising:
a header frame defining a travel axis;
at least two row dividers comprising a first row divider and a second row divider carried by the header frame and defining a gap therebetween, the first row divider comprising a first side surface and the second row divider comprising a second side surface; and
a crop material saver disposed in the gap and comprising a pair of saver flaps comprising a first saver flap comprising a first mounting portion mounted to the first side surface of the first row divider and a second saver flap comprising a second mounting portion mounted to the second side surface of the second row divider, each of the saver flaps being positioned such that the saver flaps co-act as a one-way pass-through to allow crop material flow past the saver flaps in an admission direction and inhibit crop material flow past the saver flaps in an inhibited direction opposite the admission direction, each of the saver flaps defining a non-perpendicular angle relative to the travel axis, the first mounting portion and the second mounting portion each defining a respective non-perpendicular angle relative to the travel axis.

2. The header of claim 1 , wherein the first saver flap and the second saver flap contact one another to define a crop admission region of the crop material saver.

3. The header of claim 2 , wherein an edge of the first saver flap contacts a surface of the second saver flap.

4. The header of claim 1 , wherein the first side surface comprises a first flat portion to which the first mounting portion mounts and the second side surface comprises a second flat portion to which the second mounting portion mounts.

5. The header of claim 4 , wherein the first flat portion is recessed inwardly relative to a lateral edge of the first row divider and the second flat portion is recessed inwardly relative to a lateral edge of the second row divider.

6. The header of claim 1 , further comprising a pair of deck plates carried by the header frame and defining a deck plate channel therebetween, the crop material saver having a portion disposed above the deck plate channel.

7. The header of claim 1 , wherein each of the saver flaps comprises rubber.

8. The header of claim 1 , wherein the non-perpendicular angle of the first mounting portion defines the non-perpendicular angle of the first saver flap and the non-perpendicular angle of the second mounting portion defines the non-perpendicular angle of the second saver flap.

9. An agricultural vehicle, comprising:
a chassis defining a travel axis; and
a header carried by the chassis, the header comprising:
a header frame;
at least two row dividers comprising a first row divider and a second row divider carried by the header frame and defining a gap therebetween, the first row divider comprising a first side surface and the second row divider comprising a second side surface; and
a crop material saver disposed in the gap and comprising a pair of saver flaps comprising a first saver flap comprising a first mounting portion mounted to the first side surface of the first row divider and a second saver flap comprising a second mounting portion mounted to the second side surface of the second row divider, each of the saver flaps being positioned such that the saver flaps co-act as a one-way pass-through to allow crop material flow past the saver flaps in an admission direction and inhibit crop material flow past the saver flaps in an inhibited direction opposite the admission direction, each of the saver flaps defining a non-perpendicular angle relative to the travel axis, the first mounting portion and the second mounting portion each defining a respective non-perpendicular angle relative to the travel axis.

10. The agricultural vehicle of claim 9 , wherein the first saver flap and the second saver flap contact one another to define a crop admission region of the crop material saver.

11. The agricultural vehicle of claim 10 , wherein an edge of the first saver flap contacts a surface of the second saver flap.

12. The agricultural vehicle of claim 9 , wherein the first side surface comprises a first flat portion to which the first mounting portion mounts and the second side surface comprises a second flat portion to which the second mounting portion mounts.

13. The agricultural vehicle of claim 12 , wherein the first flat portion is recessed inwardly relative to a lateral edge of the first row divider and the second flat portion is recessed inwardly relative to a lateral edge of the second row divider.

14. The agricultural vehicle of claim 9 , further comprising a pair of deck plates carried by the header frame and defining a deck plate channel therebetween, the crop material saver having a portion disposed above the deck plate channel.

15. The agricultural vehicle of claim 9 , wherein each of the saver flaps comprises rubber.

16. The agricultural vehicle of claim 9 , wherein the non-perpendicular angle of the first mounting portion defines the non-perpendicular angle of the first saver flap and the non-perpendicular angle of the second mounting portion defines the non-perpendicular angle of the second saver flap.
