Abstract
A hammer-ripper system for use with the mounting on the boom arm, of an excavator/backhoe, of a conventional hydraulically-operated hammer fitted with a “shortened” chisel. A “ripping-type” device like a chisel tooth mounts to a lever with its pivot point attached to the side of the hammer. One end of the lever extends to be impacted by under the shortened chisel, while the other end extends inward. Thus, the tooth end can be placed under embedded boulders and used to hammer (using the transmitted reciprocating action of the hydraulic hammer), and pry or break up the boulders from underneath with the combined hammering and ripping action.
Claims20
An excavator tool system for use with an excavator boom arm comprising at least two articulated segments, for providing combination impact and other forces during excavation of material, comprising, in combination:
- a) a transmitting means for transmitting reciprocating impact forces in a first direction;
- b) a direction-changing means, removably attached to said transmitting means, for receiving said reciprocating impact forces from said transmitting means and for changing said first direction of said reciprocating impact forces at least about 90 degrees to a second direction;
- and
- c) an impact means, connected with said direction-changing means, for providing combination impact, in said second direction, and other forces to the material;
- d) wherein said transmitting means is adapted for attachment to the excavator boom arm.
An excavator tool system for use with an excavator boom arm comprising at least two articulated segments, for providing combination impact and other forces during excavation of material, comprising, in combination:
- a) an impact-force transmitter structured and arranged to transmit reciprocating impact forces in a first direction;
- b) a force redirector, removably attached to said impact-force transmitter, structured and arranged to receive said reciprocating impact forces from said impact-force transmitter and to change said first direction of said reciprocating impact forces at least about 90 degrees to a second direction;
- c) a force-transmitting tool, connected with said force redirector, structured and arranged to provide combination impact, in said second direction, and other forces to the material;
- and
- d) wherein said impact-force transmitter is structured and arranged to be attached to the excavator boom arm.
An excavator tool system for use with an excavator boom arm comprising at least two articulated segments, for providing combination impact and other action for assisting in displacing material, comprising, in combination:
- a) an impactor tool structured and arranged to provide a rapid series of power-driven impacts in a first direction;
- b) said impactor tool structured and arranged to be attached to the excavator boom arm;
- and
- c) a second tool, removably attached to said impactor tool, structured and arranged
- i) to provide an other action than impacting, and
- ii) to be impacted upon by said impactor tool and to transmit the power-driven impacts in a second direction at least about 90 degrees to the first direction, and
- iii) to combine impact action with said other action to act upon the material.
