Abstract
An improved sugar cane grab loader has a hydraulically actuated grab and supporting boom, and a mechanical pushpiler. The pushpiler has floating teeth to prevent undue ground penetration during its scraping action. The teeth move in free but limited fashion in a rearwardly inclined direction. The boom lifts the grab from the soil by a controlled height during closing action of the grab around the cane bundled on the ground.
Claims11
A sugar cane grab loader, comprising:
- an articulated and hydraulically actuated grab;
- a hydraulically actuated boom for lifting the grab, said grab being mounted at an end of the boom, said boom being connected to a support structure;
- means connected to said support structure for pushing sugar cane on top of soil to form bundles, said bundles adapted to be grabbed by said hydraulically actuated grab, said pushing means comprising:
- at least two main body plates, said plates being vertically oriented and substantially coplanar with the direction of pushing said cane, said plates being mounted in spaced relationship to one another;
- and a tooth articulatedly connected to each of said main body plates, each said tooth having a tip extending downwardly and forwardly from each said main body plate, said articulated connections providing means for limiting ground penetration by said tooth tips during said pushing of cane, said limiting occurring substantially without hydraulic control of said teeth and means for automatically lifting said grab a predetermined distance as a bundle of cane is grabbed.
