Abstract
A bale wagon for large bales that uses a load rack made of a plurality of longitudinal spaced-apart channel members that move in segments to transfer the load rearwardly for unloading. A tilting bed round bale unloader deposits bales one tier at a time onto their cylindrical surfaces on the ground.
Claims15
In a bale wagon for big bales, the bale wagon having a loader for picking bales up from a field, a bale manipulator for selectively rotating a bale picked up by the loader and depositing it in selective locations on a load rack, the improvement comprising:
- the load rack has a forward end and an opposing rear end with a longitudinal axis between the two being generally parallel to the direction of travel of the bale wagon, the load rack comprising:
- a plurality of elongate spaced-apart channel members extending generally between the front and rear ends of the load rack and forming a generally planar surface of approximately 50% open space, the generally planar surface having a top and an opposing bottom;
- reciprocatable power sources affixed to each channel member such that a first selective activation of one of the power sources will slide the respective channel member a predetermined distance in the desired direction of bale movement, and a second selective activation of the one power source will slide the respective channel member to its initial position;
- a control device connected to each power source and adapted to selectively and generally simultaneously initiate the first activation of all power sources such that all channel members slide together the predetermined distance;
- and
- the control device further adapted to serially initiate the second activation of individual channel members to slide it to its initial position, whereby the bale pickup may grasp and pick up a single bale from the ground, the bale may be manipulated to a desired orientation and deposited on the load rack, and moved along the load rack by the moving the channel members.

A self-propelled bale wagon for big bales, comprising:
- a wheel-supported main frame;
- a source of motive power supported on the main frame;
- a loader supported on the main frame for picking bales up from a field;
- a bale manipulator supported on the main frame for selectively receiving a bale from the loader, clamping it and selectively rotating the bale and depositing it in selective locations on a load rack having a front end and an opposing rear end and a longitudinal axis generally therebetween, the load rack comprising:
- a plurality of elongate spaced-apart channel members extending generally between the front and rear ends of the load rack and forming a generally planar surface of approximately 50% open space, the generally planar surface having a top and an opposing bottom;
- reciprocatable power sources affixed to each channel member such that a first selective activation of one of the power sources will slide the respective channel member a predetermined distance in the desired direction of bale movement, and a second selective activation of the one power source will slide the respective channel member to its initial position;
- a control device connected to each power source and adapted to selectively and generally simultaneously initiate the first activation of all power sources such that all channel members slide together the predetermined distance;
- and
- the control device further adapted to serially initiate the second activation of individual channel members to slide it to its initial position, whereby the bale pickup may grasp and pick up a single bale from the ground, the bale may be manipulated to a desired orientation and deposited on the load rack, and moved along the load rack by the moving the channel members.
