Pneumatic pavement joint cleaning system

摘要

A pneumatic cleaning system for pavement joints controlled and driven by a motor. A wheeled housing carries a nozzle system where a stream of pressurized or forced air is directed through rotating nozzles to clean the joint surfaces. The RPM of the motor are selectively controlled by actuation of a throttle by the operator, and allows the operator to selectively control the rate of rotation of the nozzles are required by the state of the surface to be cleaned. A vacuum is further positioned to remove the debris dislodged by the pneumatic system. A brush or skirt component further loosens debris for removal and contains the debris within the cleaning area for controlled removal by vacuum suction. A frame may be operably connected to the cleaning base allowing the operator to stand/walk within the frame when moving the cleaning base and where the frame is a support for at least a vacuum hose.

主权项

1. A pneumatic 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 vacuum hose connected to an outlet in the housing and the vacuum hose extending from connection with the housing to 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.
