Abstract
An improved boom-supportable device for lifting large rocks, broken concrete or asphalt pieces, and the like from the ground without particulates. The invention includes a generally upright frame member having a lower edge, a shelf-like member extending laterally from the frame lower edge to a distal end and defining substantial voids, and devices removably attaching the shelf-like member to the frame lower edge selectively in either a forward position or a rearward position. The shelf-like member preferably has a plurality of elongated parallel teeth spaced along the lower edge. The teeth are most preferably separate, each individually attached to the lower edge.
Claims19
In a device for lifting and moving large rocks and the like from the ground of the type including a vehicle, a boom with a proximal end secured to the vehicle and a distal end movable with respect to the vehicle, and a scoop member secured at the distal end, the improvement wherein the scoop member comprises:
- a frame having a horizontal upper member and extending downwardly therefrom to a lower edge;
- means secured to the horizontal upper member and pivotably connected to the boom, the connection means including a pair of spaced pivot attachment means forming separate pivot axes to allow both lifting and tilting of the frame by the boom;
- means forming a shelf extending laterally from a proximal end along the frame lower edge to a distal end, the shelf means having a multiplicity of upwardly-facing support surfaces spaced thereacross and separated by substantial laterally-extending voids therebetween, thereby to support large rocks and the like without holding particulates;
- and
- means extending along and adjacent to the lower edge to removably attach the proximal end of the shelf means to the lower edge of the frame member selectively in either a forward position or a rearward position.
A boom-supportable device for lifting and moving large rocks and the like from the ground comprising:
- means for connection to a boom;
- a frame secured to the connection means and extending downwardly therefrom to a lower edge, the frame having n upper member and, spaced therefrom, a flat horizontal lower member along the lower edge;
- a plurality of elongated parallel flat teeth spaced along the flat horizontal lower member edgewise thereon and extending laterally from proximal ends along the lower edge to distal ends to form a shelf, the teeth having substantial voids therebetween to support large rocks and the like without holding particulates and each tooth having at least one tooth hole therein along its proximal end;
- pairs of flat vertical members each affixed to the lower member and extending therefrom immediately adjacent to a flat tooth, each of the vertical members having at least one hole therein adjacent to one of the tooth holes and each such pair of vertical members receiving one of said teeth therebetween;
- at least one rod extending through the frame and through the holes in the teeth and vertical members to removably attach the teeth to the lower edge of the frame selectively in either a forward position or a rearward position;
- and
- one of the vertical members of each pair extending between the lower and upper frame members, such vertical members defining substantial voids therebetween to support large rocks and the like without holding particulates.
