Abstract

A cylindrical bale-wrapping apparatus includes a main frame having a vehicle mounting apparatus, a first sub-frame adjustably mounted on the main frame between a bale-loading position and a bale-wrapping position, and a second sub-frame adjustably mounted on the main frame between a transport position and a bale-wrapping position. A wrapping table adapted to rotate a cylindrical bale about a central axis is associated with the first sub-frame. A wrapping ring including at least one roll support adapted to rotate about the wrapping table is mounted on the second sub-frame. The second sub-frame has a bale-support element.

First claim

What is claimed is:

1. A cylindrical bale lifting and wrapping apparatus comprising:
a main frame including a vehicle mounting apparatus;
a first sub-frame adjustably mounted on the main frame and operable to move with respect to the main frame between a bale-loading position in which the first sub-frame is configured to engage a cylindrical bale resting on the ground and a bale-wrapping position in which the first sub-frame lifts the cylindrical bale off of the ground;
a second sub-frame having a bale support element mounted thereon, the bale support element extending below the second sub-frame, the second sub-frame adjustably mounted on the main frame, the second sub-frame being operable to move with respect to the main frame between a transport position and a bale-wrapping position;
a wrapping table associated with the first sub-frame, the wrapping table configured such that when the first sub-frame is in the bale-wrapping position the cylindrical bale rotates about a central axis of the cylindrical bale;
a wrapping ring mounted on the second sub-frame, the wrapping ring including at least one roll support configured such that, when the second sub-frame is in the bale-wrapping position, the at least one roll support can rotate about the wrapping table.

2. The cylindrical bale lifting and wrapping apparatus according to claim 1 , wherein at least a portion of the bale-support element is pivotable with respect to the second sub-frame as the second sub-frame is moved between the transport position and the bale-wrapping position.

3. The cylindrical bale lifting and wrapping apparatus according to claim 1 , wherein the bale-wrapping apparatus further comprises first and second side elements connected between the main frame and the bale-support element.

4. The cylindrical bale lifting and wrapping apparatus according to claim 3 , wherein the main frame, the second sub-frame, the bale-support element and the first and second side elements are in a pantographic relationship with one another.

5. The cylindrical bale lifting and wrapping apparatus according to claim 1 , wherein the bale-support element is opposite the wrapping table when both the bale-support element and the wrapping table are in their respective bale-loading positions.

6. The cylindrical bale lifting and wrapping apparatus according to claim 1 , wherein the bale-support element is curved.

7. The cylindrical bale lifting and wrapping apparatus according to claim 1 , wherein the bale-support element includes a plurality of rollers.

8. The cylindrical bale lifting and wrapping apparatus according to claim 7 , wherein the plurality of rollers are free running.

9. A method of loading a cylindrical bale from a ground surface onto a cylindrical bale-wrapping apparatus comprising a main frame including a vehicle mounting apparatus, a first sub-frame adjustably mounted on the main frame between a bale-loading position in which the first sub-frame is configured to engage a cylindrical bale resting on the ground and a bale-wrapping position in which the first sub-frame lifts the cylindrical bale off of the ground, and a second sub-frame adjustably mounted on the main frame between a transport position and a bale-wrapping position, a wrapping table associated with the first sub-frame, the wrapping table configured such that when the first sub-frame is in the bale-wrapping position a cylindrical bale can rotate about a central axis of the cylindrical bale, a wrapping ring mounted on the second sub-frame, the wrapping ring including at least one roll support and configured such that when the second sub-frame is in the wrapping position, the at least one roll support can rotate about the wrapping table and the second sub-frame having a depending bale-support element mounted thereon, the bale-support element extending below the second sub-frame, in which prior to loading of the cylindrical bale the first sub-frame is in the bale-loading position and the second sub-frame is in the transport position, the method comprising:
guiding the cylindrical bale-wrapping apparatus towards a first surface of the cylindrical bale deposited on the ground surface such that a surface of the wrapping table is adjacent the first surface of the cylindrical bale;
causing the second sub-frame to move from the transport position to the bale-wrapping position adjacent a second side of the cylindrical bale; and
causing the first sub-frame to pivot from the bale-loading position to the bale-wrapping position to raise the cylindrical bale from the ground surface and pivot the cylindrical bale within the second sub-frame.
