  • Pneumatic excavator and methods of use
    Patent number: 12264453
    Abstract: A pneumatic excavator includes: a barrel with an ingress configured to be fluidly connected to a supply of compressed air and an egress; an actuator; a releasable coupling to lock the actuator to the barrel in a plurality positions; and a flow valve fixedly arranged to the barrel, the flow valve in a communicative coupling with the actuator by an actuation conduit. The actuation conduit is flexible and slaved by an adjustment movement of the releasable coupling and actuator along the barrel to thereby maintain the communicative coupling therebetween. When the actuator is actuated, the actuation conduit sends causes the flow valve to open and the compressed air passes through the flow valve and exits the pneumatic excavator, and when the actuator is released, the actuation conduit sends a signal to the flow valve to close to prevent the compressed air from passing through the flow valve.
