Abstract: A spring loaded retainer device for securing suction wands is disclosed. The device includes a handle configured to be gripped by an operator, a hollow cylinder, and a plunger disposed within the hollow cylinder, where a proximate end of the plunger is secured to the handle used to pull the plunger outward of the hollow cylinder. In addition, the device includes a spring that surrounds the plunger and biases a distal end of the plunger inward of the hollow cylinder and when the handle is released the spring pushes the plunger inward of the hollow cylinder. Opposing lateral tips of the handle are each configured to restrain an end of a suction wand being stored inside a compartment when the handle is rotated in line with a substantially horizontal axis, where the handle is configured to be pulled outwards and rotated in line with a substantially vertical axis when removing the suction wand from the compartment.

Abstract: A folding hose storage rack is disclosed. The rack includes two spaced apart support members with each support member having a vertical member configured to rotate about a vertical axis, an upper arm extending outward from the vertical member, a lower arm extending outward from the vertical member, where the lower arm is aligned under the upper arm, and a boss along a lower edge of the lower arm. In addition, the rack includes a retainer having intersecting slots such that each slot is configured to receive the boss to prevent the support member from rotating. Each support member is configured to lift up to remove the boss from the intersecting slots, rotate to a desired position, and lower down to insert the boss into a desired slot of the intersecting slots. The intersecting slots form a T-configuration to rotate and secure each supporting arm to either side.

A hinge assembly is associated with the door to mount the door to a periphery of the open end of the debris tank for swinging movement of the door between an open and a closed position.

Abstract: A dewatering system is disclosed. In a particular embodiment, the system includes a debris tank configured to receive a slurry through an inlet and a dewatering filter installed in the debris tank. In addition, the system includes a bar screen forming a curvilinear surface of the dewatering filter, where the bar screen is configured to prevent sediment from passing through and into an interior space of the dewatering filter. A first end of the dewatering filter is in communication with a discharge port to remove filtered liquid from an interior of the debris tank, and a vibratory device is configured to shake the dewatering filter to remove sediment from an exterior surface of the dewatering filter.

Abstract: A rotating high pressure air and water nozzle is disclosed. The nozzle includes a head adapted to rotate, a housing adapted to secure the head therein, and a plurality of passageways disposed through the head. In addition, the nozzle includes a supply port disposed at a first end of each of the passageways, where each supply port has a funnel shape adapted to direct fluid into each passageway to reduce hydraulic losses, and a discharge port disposed at an opposing end of each of the passageways adapted to discharge a jet of fluid. Each discharge port is offset from the respective supply port to cause the head to rotate when fluid flows through the passageways.

Abstract: A pulsating high pressure air and water nozzle is disclosed. The nozzle includes an impeller adapted to rotate about an axis, a housing adapted to secure the impeller therein, and a supply conduit secured to the housing. The supply conduit is orientated to direct a stream of pressurized fluid to impact the impeller to cause the impeller to rotate. The nozzle also includes a discharge port secured to the housing and is adapted to discharge a pulsating stream of fluid directly from the housing. The impeller includes a plurality of radial spaced vanes secured to a hub, where a cavity is disposed between each vane of the plurality of vanes. The plurality of vanes is adapted to intermittently block the discharge port as the impeller rotates. In addition, the nozzle includes a cover adapted to be removably secured to the housing to access an inside of the housing.

Abstract: A system to separate solids from liquids is disclosed. In a particular embodiment, the system includes a series of alternating baffles disposed along a length of a tank, where the series of alternating baffles define a vertical tortuous flow path of the fluid from a first end of the tank to a second end of the tank to cause solids to settle out of the fluid. The alternating baffles each have a sloped planar surface disposed between a lower horizontal planar surface and an upper horizontal planar surface to cause at least one eddy in a vertical plane as the fluid flows through the tank. The system may also include a series of tanks in fluid communication with the at least one tank and secured side by side, where the solids progressively settle out from the fluid in stages as the fluid passes from one tank to another in series.

Abstract: A system and method to excavate using a pneumatic shock wave is disclosed. The system includes a supply of pressurized fluid, a suction wand, and an air line in communication with the supply of pressurized fluid. A portion of the air line is integrated within the suction wand. The system also includes a dump valve interposed between the supply of pressurized fluid and the portion of the air line integrated within the suction wand. The dump valve is configured to rapidly discharge a pulse of the pressurized fluid out an open end of the air line to generate a shock wave at a distal end of the suction wand to fracture and dislodge soil so that the suction wand can excavate the soil.

Abstract: A system and method to excavate using a vacuum hose is disclosed. The system includes a suction wand handle, where a first end of the suction wand handle is adapted to be secured to a suction hose and a first and second grip project from opposing sides of the suction wand handle are adapted for a user to grasp. In addition, a suction wand is secured to a second end of the suction wand handle, where the suction wand includes an open end. An air line is secured to the suction wand, where a first end of the air line is adapted to be in communication with a pressurized air source and the second end terminates in at least one air nozzle at the open end of the suction wand.

Abstract: A filter silencer is disclosed. In a particular embodiment, the silencer includes a housing, a silencer chamber disposed inside the housing, and a filter chamber disposed between a sidewall of the housing and the silencer chamber. An intake port is in communication with the filter chamber and ambient air. The filter chamber also includes a filter chamber outlet that is in communication with a compressor or air blower, for example. A silencer chamber inlet is in communication with an exhaust of the compressor or air blower, where an air flow is forced through the silencer and out a discharge port. The discharge port and the intake port are at opposing ends of the silencer. In addition, the silencer includes at least one baffle secured within the silencer chamber, where the baffle is configured to generate a non-directional interference with the air flow to assist in silencing the discharge.

Abstract: A system and method to excavate and fill is disclosed. The system includes a canister adapted to receive and store excavated material. In addition, a plurality of blades are mounted inside of the canister about a horizontal shaft proximate a bottom end of the canister. A motor is adapted to rotate the plurality of blades to move the excavated material stored in the canister to the bottom end of the canister and a blower is adapted to blow the excavated material at the bottom end of the canister out of an opposing side of the canister through a discharge port. The canister includes a downward sloping lip disposed above the plurality of blades, where the downward sloping lip funnels the excavated material on to a downwardly rotating blade of the plurality of blades.
