Abstract

An agricultural machine system includes a baling system. The baling system includes a bale forming region. The baling system also includes a tensioning arm rotatably coupled to a frame of the baling system at a pivot. The baling system also includes a first plurality of rollers disposed about the bale forming region. The baling system also includes a second plurality of rollers rotatably coupled to the tensioning arm. The baling system also includes a bale forming belt disposed about the bale forming region. The bale forming belt is engaged with the first plurality of rollers and the second plurality of rollers. A rotational axis of the pivot is positioned below a longitudinal central axis of a fully-formed bale disposed in the bale forming region at an end of a bale forming stage. At least a portion of each roller of the first plurality of rollers is disposed below a height of the fully-formed bale at the end of the bale forming stage.

First claim

The invention claimed is:

1. An agricultural machine system comprising:
a baling system comprising:
a bale forming region;
a tensioning arm rotatably coupled to a frame of the baling system at a pivot;
a first plurality of rollers disposed about the bale forming region;
a second plurality of rollers rotatably coupled to the tensioning arm; and
a bale forming belt disposed about the bale forming region, wherein the bale forming belt is engaged with the first plurality of rollers and the second plurality of rollers;

wherein a rotational axis of the pivot is positioned below a longitudinal central axis of a fully-formed bale disposed in the bale forming region at an end of a bale forming stage; and
wherein at least a portion of each roller of the first plurality of rollers is disposed below a height of the fully-formed bale at the end of the bale forming stage.

2. The agricultural machine system of claim 1 , wherein the baling system comprises a feeding system and a bale wrapping system, wherein the feeding system and the bale wrapping system are disposed in front of the bale forming region and below the height of the fully-formed bale.

3. The agricultural machine system of claim 2 , wherein the bale wrapping system is configured to wrap the fully-formed bale while the fully-formed bale is rotating in a direction that causes a top portion of the fully-formed bale to move toward a front side of the bale forming region.

4. The agricultural machine system of claim 1 , wherein the baling system comprises a pendulum arm configured to:
unwrap a portion of the bale forming belt from a perimeter of the fully-formed bale via rotation of the pendulum arm about the fully-formed bale; and
facilitate ejection of the fully-formed bale from the bale forming region in response to the rotation.

5. The agricultural machine system of claim 1 , comprising one or more actuators directly coupled to the tensioning arm, the one or more actuators configured to drive the tensioning arm to rotate about the pivot, wherein the pivot is disposed in front of the bale forming region.

6. The agricultural machine system of claim 1 , wherein the first plurality of rollers comprises:
a first roller disposed partially above the height of the fully-formed bale at a first height and in front of the bale forming region; and
a second roller disposed partially above the height of the fully-formed bale at a second height and behind the bale forming region;
wherein the first and second heights are equal.

7. The agricultural machine system of claim 6 , wherein a section of the bale forming belt extends from the first roller to the second roller, the section of the bale forming belt comprises a straight path of the bale forming belt, and the section of the bale forming belt is disposed above the height of the fully-formed bale.

8. The agricultural machine system of claim 7 , wherein the first plurality of rollers is configured to be disposed below the section of the bale forming belt at the end of the bale forming stage.

9. The agricultural machine system of claim 7 , wherein ends of the section of the bale forming belt extend past ends of a longitudinal extent of the fully-formed bale.

10. The agricultural machine system of claim 1 , wherein the tensioning arm is configured to rotate from a first angle at a beginning of the bale forming stage to a second angle at the end of the bale forming stage.

11. The agricultural machine system of claim 10 , wherein the first and second angles fall within first and second angle windows, respectively, the first angle window spans plus or minus 20 degrees relative to a 40-degree angle from a longitudinal axis, and the second angle window spans from 45 degrees to 90 degrees relative to the longitudinal axis.

12. An agricultural machine system comprising:
a baling system comprising:
a bale forming region;
a tensioning arm rotatably coupled to a frame of the baling system at a pivot;
a first plurality of rollers disposed about the bale forming region comprising first and second rollers;
a second plurality of rollers rotatably coupled to the tensioning arm; and
a bale forming belt disposed about the bale forming region, wherein the bale forming belt is engaged with the first plurality of rollers and the second plurality of rollers;

wherein the bale forming belt comprises a horizontal portion, the horizontal portion extending from the first roller to the second roller;
wherein a rotational axis of the pivot is positioned below a longitudinal central axis of a fully-formed bale disposed in the bale forming region at an end of a bale forming stage;
wherein at least a portion of each roller of the first plurality of rollers is disposed below a height of the fully-formed bale at the end of the bale forming stage;
wherein the first plurality of rollers is disposed below the horizontal portion of the bale forming belt, the horizontal portion disposed above the fully-formed bale at the end of the bale forming stage;
wherein the horizontal portion of the bale forming belt extends past a longitudinal extent of the fully-formed bale at the end of the bale forming stage;
wherein the first and second rollers are disposed at least partially above the height of the fully-formed bale.

13. The agricultural machine system of claim 12 , comprising one or more actuators directly coupled to the tensioning arm, the one or more actuators configured to drive the tensioning arm to rotate about the pivot, wherein the pivot is disposed in front of the bale forming region.

14. The agricultural machine system of claim 12 , wherein the horizontal portion of the bale forming belt is configured to be disposed above the height of the fully-formed bale by a gap, wherein a width of the gap does not exceed 10 percent of a diameter of the fully-formed bale.

15. The agricultural machine system of claim 14 , wherein the width of the gap does not exceed a larger of first and second diameters of the first and second rollers, respectively.

16. An agricultural machine system comprising:
a baling system comprising:
a bale forming region;
a tensioning arm rotatably coupled to a frame of the baling system at a pivot;
a pendulum arm coupled to the bale forming region;
a first plurality of rollers disposed about the bale forming region;
