First Claim
Patent Images
1. An apparatus for gathering bales resting on a surface, the apparatus comprising:
- ground-engaging wheels or tracks for moving the apparatus relative to the surface at a ground speed;
a bed for holding one or more bales and having a first side and a second side opposite the first side, the bed comprising a conveyor belt toward the first side of the bed and a conveyor belt toward the second side, the bed not having more than two conveyor belts opposite each other;
a loading assembly for grasping and lifting a bale and conveying it to the bed and comprising a first arm comprising a first conveyor belt and a second arm comprising a second conveyor belt, the loading assembly not comprising more than two conveyor belts; and
a drive system coupled to the ground-engaging wheels or tracks for controlling and varying a speed of the first and second conveyor belts of the loading assembly to match the ground speed of the apparatus, the drive system not varying the speed of the first and second conveyor belts from a pulling vehicle.

12. An apparatus for gathering bales resting on a surface, the apparatus comprising:
-
ground-engaging wheels or tracks for moving the apparatus relative to the surface at a ground speed; a bed for holding one or more bales and having a first side and a second side opposite the first side, the bed comprising a conveyor belt toward the first side of the bed and a conveyor belt toward the second side, the bed not having more than two conveyor belts opposite each other; a loading assembly for grasping and lifting a bale and conveying it to the bed, the loading assembly being separate from the bed and comprising a first arm comprising a first conveyor belt and a second arm comprising a second conveyor belt, the loading assembly not comprising more than two conveyor belts; and a hydraulic device coupled to the ground-engaging wheels or tracks for controlling and varying a speed of the first and second conveyor belts of the loading assembly to match the ground speed of the apparatus, the hydraulic device not varying the speed of the first and second conveyor belts from a pulling vehicle. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A method for gathering bales resting on a surface by use of an apparatus for gathering bales, the apparatus comprising ground-engaging wheels or tracks, a bed for holding one or more bales, a loading assembly for lifting a bale and conveying it toward the bed, the loading assembly comprising a first arm comprising a first conveyor belt and a second arm comprising a second conveyor belt, and a drive system or hydraulic device coupled to the ground-engaging wheels or tracks for controlling and varying a speed of the first and second conveyor belts of the loading assembly to match the ground speed of the apparatus, the method comprising:
-
propelling the apparatus over the surface on which the bales rest and toward a bale at a ground speed; actuating the first conveyor belt and the second conveyor belt while directing the apparatus toward the bale wherein the apparatus controls and varies a speed of the first and second conveyor belts to be substantially equal to the ground speed of the apparatus without input from an operator; loading a bale onto the first and second conveyor belts of the loading assembly; and conveying the bale from the loading assembly to the bed.

22. An apparatus for gathering bales resting on a surface, the apparatus comprising:
-
ground-engaging wheels or tracks for moving the apparatus relative to the surface at a ground speed; a bed having a first side and a second side opposite the first side, the bed comprising a conveyor belt toward the first side of the bed and a conveyor belt toward the second side, the bed not having more than two conveyor belts opposite each other; a loading assembly for grasping and lifting a bale and conveying it to the bed, the loading assembly being separate from the bed and comprising a first arm comprising a first conveyor belt and a second arm comprising a second conveyor belt, the loading assembly not comprising more than two conveyor belts; a drive system for controlling a speed of the first and second conveyor belts of the loading assembly to match the ground speed of the apparatus; a controller for adjusting a speed of the first conveyor belt and the second conveyor belt such that the speed of the first and/or second conveyor belts is substantially equal to the ground speed of the apparatus; and a speed sensor to detect the speed of the apparatus, the speed sensor being coupled to the controller to send a signal to the controller. - View Dependent Claims (23, 24, 25)
