Abstract

A baler including a frame a feed assembly coupled to the frame, an auger housing coupled to the frame and in operable communication with the feed assembly, the auger housing having an exterior wall including a first open end, a second open end opposite the first open end, and defining a volume therein. The baler also including a first auger at least partially positioned within the volume and rotatable with respect to the auger housing about a first axis, and a second auger at least partially positioned within the volume and rotatable with respect to the auger housing about a second axis.

First claim

What is claimed is:

1. A baler comprising:
a frame;
a feed assembly coupled to the frame;
an auger housing coupled to the frame and in operable communication with the feed assembly, the auger housing having an exterior wall including a first open end, a second open end opposite the first open end, and defining a volume therein;
a first auger at least partially positioned within the volume and rotatable with respect to the auger housing about a first axis, wherein the first axis passes through the first open end and the second open end;
a second auger at least partially positioned within the volume and rotatable with respect to the auger housing about a second axis, wherein the second axis passes through the first open end and the second open end; and
a bale case coupled to the frame and in operable communication with the volume of the auger housing, wherein the bale case is configured to apply a resistive force against a forming bale positioned therein, and wherein both the first auger and second auger convey crop material directly into the bale case.

2. The baler of claim 1 , wherein the first axis and the second axis lie on a first plane.

3. The baler of claim 1 , wherein the first axis is parallel to the second axis.

4. The baler of claim 1 , wherein the auger housing defines a third axis extending along the length of the auger housing proximate its center, and wherein at least one of the first axis and the second axis is parallel to the third axis.

5. The baler of claim 1 , wherein the feed assembly includes a pickup assembly, and an accelerator roll.

6. The baler of claim 1 , wherein at least one of the first auger and the second auger comprises a core and at least one flight.

7. The baler of claim 6 , wherein at least one of the first auger and the second auger includes two flights positioned 180 degrees from one another.

8. The baler of claim 6 , wherein the at least one flight originates proximate a front end of the core and extends axially rearwardly in a helical pattern.

9. The baler of claim 8 , wherein the at least one flight makes between approximately one-half and approximately two rotations about the core.

10. A baler comprising:
a frame;
a feed assembly coupled to the frame;
an auger housing coupled to the frame and configured to receive crop material from the feed assembly, the auger housing having an exterior wall including a first open end, a second open end opposite the first open end, and wherein the exterior wall defines a volume therein;
a first auger at least partially positioned within the volume and rotatable with respect to the auger housing about a first axis, wherein the first auger includes a flight defining a first flight diameter;
a second auger at least partially positioned within the volume and rotatable with respect to the auger housing about a second axis, wherein the second auger includes a flight defining a second flight diameter,
wherein the first axis is parallel to the second axis, and wherein the first axis is spaced a first distance from the second axis that is greater than the larger of the first flight diameter and the second flight diameter; and
a bale case coupled to the frame and in operable communication with the volume of the auger housing, wherein the bale case is configured to apply a resistive force against a forming bale positioned therein, and wherein both the first auger and second auger axially discharge crop material directly into the bale case.

11. The baler of claim 10 , wherein the first flight and the second flight do not overlap in the direction of the first distance.

12. The baler of claim 10 , wherein the auger housing defines a third axis extending along the length of the auger housing proximate its center, and wherein at least one of the first axis and the second axis is parallel to the third axis.

13. The baler of claim 10 , wherein the first axis and the second axis lie on a first plane.

14. The baler of claim 13 , wherein the auger housing defines a third axis extending along the length of the auger housing proximate its center, and wherein the first plane is defined by the direction of the first distance and the third axis.

15. The baler of claim 10 , wherein the auger housing defines a third axis extending along the length of the auger housing proximate its center, and wherein the cross-sectional shape of the volume taken perpendicular to the third axis is rectangular in shape.

16. The baler of claim 15 , wherein the cross-sectional shape of the volume includes a first dimension in the direction of the first distance, and a second dimension perpendicular the direction of the first distance, and wherein the first dimension is greater than the second dimension.

17. The baler of claim 10 , further comprising a drive assembly, and wherein the drive assembly is configured to rotate the first auger and the second auger at a first rotational speed.

18. The baler of claim 17 , wherein the drive assembly is configured to rotate the first auger in a first rotational direction, and the second auger in a second rotational direction opposite the first rotational direction.
