Pneumatic excavator and methods of use

A pneumatic excavator, comprising:

• an elongated barrel having an ingress and an egress, the ingress configured to be fluidly connected to a supply of compressed air, the egress defining an outlet of the pneumatic excavator;
• an actuator comprising an actuation switch;
• a releasable coupling configured to releasably couple the actuator to the barrel in a plurality of locked positions along a length of the barrel, such that the actuator is movably coupled to an exterior of the barrel;
• and
• a flow valve fixedly arranged to the barrel, wherein the flow valve is in a communicative coupling with the actuator by an actuation conduit,
• wherein the actuation conduit comprises tubing that is flexible and telescopic and is slaved by an adjustment movement of the actuator relative to the flow valve along the length of the barrel to thereby maintain the communicative coupling therebetween such that when the actuator is actuated, the actuation conduit sends a signal of compressed air emitted from the actuator to the flow valve to move to an open position and the supply of compressed air passes through the flow valve and the barrel and exits the pneumatic excavator through the outlet, and when the actuator is released, the actuation conduit sends another signal of compressed air to the flow valve to move to a closed position to prevent the supply of compressed air from passing through the flow valve.
