ABSTRACT:
A new loader bucket vibrational sifting system for separating rock and other abrasive material from dirt extracted from a trench for a pipe line, thereby allowing the user to fill in the trench after laying the pipe with the sifted dirt eliminating contact by rock or other abrasive material with the pipeline and, thereby, preclude rusting, corrosion, or like damage. The inventive device includes a sifting structure formed to pivotally enclose a conventional loader bucket, a vibrating means secured near the pivoting end of the sifting structure for vibrating the sifting structure, and a hydraulic releasing means pivotally secured at one end to the sifting structure and pivotally secured at the opposite end to the conventional loader bucket manipulating the sifting structure to allow rocks to be released.
