Pneumatic pavement joint cleaning system

A frame for a paver joint cleaning system comprising:

• a first section having two opposing side rails extending from operable connection with a wheeled housing and the two opposing rails connected by a third rail positioned in a transverse direction such that the first section of the frame is substantially “H” shaped;
• a second section extending from the first section where in the second section comprises two opposing side rails which are oriented to converge at terminal ends of each side rail and the side rails connection by a third rail positioned in a transverse direction such that the second section of the frame is substantially “A” shaped;
• and
• wherein the frame comprises an open space configured for an operator to be positioned during operation of the wheeled housing.

A method of cleaning a surface area comprised of a plurality of pavers and having at least one paver joint, the method comprising:

• providing a housing having a rotatable wand with at least one nozzle configured to direct an airflow from the nozzle;
• providing air flow from a pneumatic source to the at least one nozzle;
• providing a hose connected to an outlet in the housing and connecting the hose to a vacuum source for creating suction through the outlet;
• moving the housing over a selected area comprising the plurality of pavers at least one paver joint and rotating the at least one nozzle providing an outwardly airflow;
• adjusting the rotation of the wand within the housing by selectively adjusting the RPM of a motor that is connected to the nozzle by a belt and pulley system configured to transfer torque from the motor to the wand;
• and
• removing debris dislodged by the air flow from the nozzle by positioning the inlet of the vacuum house near the debris.

A pavement joint cleaning system comprising:

• a wheeled housing comprising at least one wheel having a ground engaging surface;
• a rotatable shaft carrying at least one nozzle and secured within the wheeled housing and configured to hover over a ground surface;
• a source of compressed gas operably connected to the rotatable shaft for providing pressurized gas flow outwardly through the nozzle;
• a source of liquid operably connected to the operable connection of the source of compressed gas for selectively providing a pressurized mixture of gas and liquid flow outwardly through the nozzle
• a vacuum hose having a selectively positionable inlet and the vacuum hose extending to connection with a vacuum source;
• and
• a motor operably connected to the rotatable shaft and a belt configured to transfer torque from the motor to the rotatable shaft allowing an operator to selectively control the rate of rotation of the shaft and thus the at least one nozzle.

A method of cleaning a surface area comprised of a plurality of pavers and having at least one paver joint, the method comprising:

• providing a housing having a rotatable wand with at least one nozzle configured to direct a jet of a gas and liquid mixture from the nozzle;
• providing gas flow from a pneumatic source to the at least one nozzle;
• providing liquid flow from a supply source to the at least one nozzle, where in the gas flow and liquid flow turbulently mix while flowing to the nozzle to provide a gas/liquid jet through the nozzle;
• providing a hose having an inlet and positioning the inlet neat the housing and connecting the hose to a vacuum source for creating suction through the inlet;
• moving the housing over a selected area comprising the plurality of pavers at least one paver joint and rotating the at least one nozzle providing an outwardly airflow;
• adjusting the rotation of the wand within the housing by selectively adjusting the RPM of a motor that is connected to the nozzle by a belt and pulley system configured to transfer torque from the motor to the wand;
• and
• removing debris dislodged by the air flow from the nozzle by positioning the inlet of the vacuum house near the debris.
