  • Patent number: 4609050
    Abstract: A root picker includes a main frame supporting within it a triangular picker frame pivoted on the main frame at one apex with a lower and rearwardly positioned apex supporting a picker roller which is rotated to pick stones from the ground. A conveyor chain supporting transverse bars with outwardly extending teeth is pivotally mounted adjacent the third apex of the frame upwardly and rearwardly of the picker roller so that the chain turns around an axis at a position alongside the picker roller to lift rocks between the conveyor chain and the picker roller onto a surface which leads up to a bucket. The frame pivots to lift the conveyor chain and the picker roller away from the ground and also the conveyor chain is pivotal relative to the frame to increase the spacing between the chain and the picker roller. Rotating sweep drums are positioned forwardly and outwardly of the frame to pick and sweep rocks into the picker roller.
