Abstract
A reciprocating adjunct for conventional backhoe buckets including a shaft which is supported on bearings and carried on connecting links depending from a bucket curl mechanism which is supported by transverse links extending to a dipper stick associated with conventional backhoe buckets, the shaft including termini having cam surfaces communicating with bearings supporting bucket brackets providing with the dipper stick the sole supports for the bucket whereby rotation of the shaft and therefor the associated cam surfaces causes a reciprocating oscillating motion of the bucket.
Claims3
A reciprocating device for a backhoe bucket which includes a downwardly extending dipper stick having respective ends pivotally connected and supporting an associated pair of bucket brackets, the bucket brackets having a contour complemental to an end wall of the bucket to support same, and a bucket curl cylinder and piston connected to the dipper stick by means of transverse links, similarly pivoted, and a pair of connecting links extending from the intersection of the bucket curl cylinder/piston and the transverse link to a further area on the bucket bracket, the reciprocating device including:
- shaft means being the connection between the connecting links and the bucket brackets,
- said shaft means rotatably supported by the connecting links by a bearing means and provided with means for rotating said shaft, said rotating means encased in a housing disposed between said pair of connecting links, and
- cam means associated with said shaft means and connecting the connecting links to the bucket brackets, whereby rotation of said shaft means imparts reciprocal oscillating motion to the bucket bracket and therefor the backhoe bucket.
