Patent ID: 8870296

Claim:
A hydraulic hammer ripper for mechanical diggers comprising a tooth with drive devices attached by means of attachment items to a headstock connected to a mechanical digger, wherein the drive devices are solidly attached to a power accumulator which is an air cushion or pneumatic cylinder; wherein the tooth, the drive devices, and the power accumulator together form an assembly that is mounted on the longitudinal axis of the tooth that strikes the ground by means of the tooth moving between a withdrawn and a deployed position, wherein when the tooth is being raised said accumulator is charged whereas when the tooth is being dropped, said accumulator discharges in such a way that the energy stored in the power accumulator is released when the tooth drops towards the ground; and wherein the drive devices are connected to a hydraulic motor that receives pressure and oil flow from the mechanical digger, which ensures that the drive devices turn in opposite directions to each other, and generate a force vector axis when they rotate, wherein the drive devices consist of a first cam and a second cam that are symmetrically disposed with respect to the force vector axis of the tooth defined by the line that runs from the apex of the tip on the tooth and passes through rotation points on said tooth, and wherein the shaft of the first cam is engaged with a shaft of the second cam such that the tooth assumes a withdrawn and a deployed position along said force vector axis.
