Abstract:
A rock bucket attachment for securement with a skid steer unit or tractor front loader, the attachment incorporating a bucket for use in combination with a grapple, the bucket having side walls, back walls, and a bottom wall, at least one pair of grapples interconnecting by lever arms to the side walls of the bucket, said at least one pair of grapples having a pair of side arms pivotally connected with the front of the lever arms, and hydraulic cylinders interconnecting between the back of the side arms and the back end of the side walls, or the frame structure interconnecting between the two, such that when the hydraulic cylinders are actuated, they initially pivot the lever arms forwardly to their fullest extent to arrange the grapples and its rake over a debris pile, and then further actuation of the hydraulic cylinders pivoting the side arms relative to the lever arms to pivot the rake of each grapple downwardly to urge any debris onto the bucket as the rake comes into proximity with the front of the bucket, to retain any raked debris therein. There are at least a pair or more of grapples operatively associated with the rock bucket attachment.

Claim (Index 1):
A rock bucket attachment incorporating sweep-in grapple for pick up and conveying of miscellaneous debris, including rocks, boulders, trees, and other debris, comprising:\n a bucket, said bucket having a pair of side walls, a back wall attaching with said side walls, and a bottom wall formed connecting with the approximate bottom of said back wall and located at its sides proximate the bottom of said side walls, and a cross bar connecting between the lower front of the side walls and securing the front of the bottom wall therewith, an upper frame connecting between the approximate upper back of said side walls; at least a pair of grapples, each grapple incorporating a pair of spaced apart side arms, and said bottom wall formed as a structural rake provided affixed between said pair of side arms, and a pair of lever arms, said lever arms pivotally connecting with the side arms, the opposite end of each lever arm pivotally connecting with the approximate upper back of each side wall, or upper frame of the back wall, the opposite end of each lever arm pivotally connecting with the approximate upper back of each side wall or upper frame, at least one hydraulic cylinder interconnecting to the upper portion of each grapple between the lever arms, said hydraulic cylinder incorporating a cylinder rod, and a cylinder rod pivotally connecting to the structural rake and which when actuated provided for compound movement of the structural rake and its side arms initially forwardly, and then pivotally downwardly for sweeping debris into the formed bucket, so that when the hydraulic cylinder is actuated, it pivots its grapple with the rake forwardly, and then upon further actuation of the hydraulic cylinder pivoting the structured rake of the grapple in a downward pivot and into contiguity with the front of the bottom wall of the bucket to rake in and pick up any rock or other debris from the surface of the ground.
