Abstract

A baler includes a frame and a bale chamber structure that is supported by the frame. The bale chamber structure includes a plurality of walls that cooperate to define a baling chamber that extends along a longitudinal axis. The plurality of walls shape different sides of the bale. At least one of the plurality of walls includes a first segment panel that is moveably attached to the frame and a second segment panel that is arranged in a downstream direction from the first segment panel with respect to the longitudinal axis. The second segment panel is moveably attached to the frame independent of the first segment panel.

First claim

What is claimed is:

1. A baler configured to form a bale of crop material, the baler comprising:
a frame;
a bale chamber structure that is supported by the frame, the bale chamber structure including a first wall and a second wall that cooperate to define a baling chamber in which the bale is formed that extends along a longitudinal axis, the first and second walls configured to shape different sides of the bale, wherein the first wall includes:
a first segment panel that is moveably attached to the frame; and
a second segment panel that is arranged in a downstream direction from the first segment panel with respect to the longitudinal axis, the second segment panel being moveably attached to the frame independent of the first segment panel, wherein the first segment panel and the second segment panel cooperate in the forming of the bale in the baling chamber; and

wherein the second wall includes:
a third segment panel that is moveably attached to the frame; and
a fourth segment panel that is arranged in a downstream direction from the first segment panel with respect to the longitudinal axis, the fourth segment panel being moveably attached to the frame, the fourth segment panel being decoupled from the third segment panel and configured for movement independent of the third segment panel.

2. The baler of claim 1 , wherein the first segment panel is moveably attached to the frame via a first joint;
wherein the second segment panel is moveably attached to the frame via a second joint; and
wherein the first joint and the second joint are spaced apart along the longitudinal axis.

3. The baler of claim 2 , wherein at least one of the first joint and the second joint is a pivot joint.

4. The baler of claim 3 , wherein the first segment panel is moveably attached to the frame via the pivot joint;
wherein the pivot joint is configured to rotate the first segment panel about an axis of rotation;
wherein the first segment panel includes an upstream end and a downstream end; and
wherein the axis of rotation is proximate the upstream end.

5. The baler of claim 4 , wherein the axis of rotation extends substantially along a vertical direction.

6. The baler of claim 2 , wherein the frame includes a first elongate member and a second elongate member that extend along the longitudinal axis;
wherein the first elongate member and the second elongate member are spaced apart in a direction that is transverse to the longitudinal axis; and
wherein at least one of the first joint and the second joint is attached to the first elongate member and the second elongate member.

7. The baler of claim 1 , further comprising an actuator system with a first actuator and a second actuator;
wherein the first actuator is configured to actuate the first segment panel relative to the frame independent of the second segment panel; and
wherein the second actuator is configured to actuate the second segment panel relative to the frame independent of the first segment panel.

8. The baler of claim 7 , wherein the first actuator is configured to rotate the first segment panel relative to the frame about a first axis of rotation; and
wherein the second actuator is configured to rotate the second segment panel relative to the frame about a second axis of rotation.

9. The baler of claim 7 , further comprising a control system configured to communicate with the first actuator for controlled actuation of the first segment panel; and
wherein the control system is configured to communicate with the second actuator for controlled actuation of the second segment panel.

10. The baler of claim 1 , wherein the frame includes a first elongate member and a second elongate member that extend along the longitudinal axis;
wherein the first elongate member and the second elongate member are spaced apart to define an opening therebetween; and
wherein the first segment panel and the second segment panel are received within the opening and are configured to move within the opening relative to the frame.

11. The baler of claim 1 , wherein the first segment panel includes a first upstream end and a first downstream end;
wherein the second segment panel includes a second upstream end and a second downstream end;
wherein the second upstream end is disposed proximate the first downstream end;
wherein the first segment panel is configured for movement independent of the second segment panel to vary a gap defined between the second upstream end and the first downstream end.

12. A baler configured to form a bale of crop material, the baler comprising:
a frame;
a bale chamber structure that is supported by the frame and defines an inlet and an outlet, the bale chamber structure including a plurality of walls that cooperate to define a baling chamber in which the bale is formed that extends along a longitudinal axis, the plurality of walls configured to shape different sides of the bale, at least one of the plurality of walls including:
a first segment panel that is moveably attached to the frame; and
a second segment panel that is arranged in a downstream direction from the first segment panel with respect to the longitudinal axis, the second segment panel being moveably attached to the frame independent of the first segment panel, wherein the first segment panel and the second segment panel cooperate in the forming of the bale in the baling chamber; and

a compaction member disposed proximate the inlet of the baling chamber and configured to move the crop material away from the inlet of the baling chamber toward the outlet of the baling chamber and form the bale; and
wherein the first segment panel is disposed proximate the compaction member; and
wherein the second segment panel partly defines the outlet.

13. A method of operating a baler having a bale chamber structure that defines a variable baling chamber in which the bale is formed that extends along a longitudinal axis, the baling chamber partly defined by a wall configured to define a side of a bale of crop material, the method comprising:
actuating a first segment panel of the wall relative to a frame about a first joint that moveably attaches the first segment panel to the frame; and
actuating a second segment panel of the wall relative to the frame about a second joint that moveably attaches the second segment panel to the frame independent of the first segment panel;
wherein the first segment panel and the second segment panel cooperate in the forming of the bale in the baling chamber; and
wherein at least one of actuating the first segment panel and actuating the second segment panel includes rotating the one of the first panel and the second panel relative to the frame about an axis of rotation that extends substantially along a vertical direction.

14. The method of claim 13 , further comprising determining, by a processor of a control system, a baling chamber characteristic;
wherein actuating the first segment panel includes actuating the first segment panel according to the baling chamber characteristic; and
wherein actuating the second segment panel includes actuating the second segment panel according to the baling chamber characteristic.

15. The method of claim 14 , wherein the baling chamber characteristic is a dimension of the baling chamber.

16. The method of claim 14 , wherein the baling chamber characteristic is a chamber pressure characteristic.

17. A baler configured to form a rectangular bale of crop material, the baler comprising:
a frame with a first elongate member and a second elongate member that are spaced apart
