ABSTRACT:
A material-removal system can include a spray-head assembly with a plurality of rotatable fluid bars arranged in a single shroud with overlapping sweeps. A gear-box assembly can index the rotations of the fluid bars to coordinate their rotation and prevent the fluid bars from interfering with one another. The material-removal system can be mounted on a mobile platform, such as a vehicle. The vehicle can have a fluid-storage tank and a debris tank that can be tilted for dumping operation while the fluid-storage tank remains stationary. A peristaltic pump can advantageously remove liquid waste from the debris tank while a vacuum system has the debris tank operating under vacuum. The spray-head assembly can be coupled to the vehicle with an articulating-arm assembly that can include a four-bar mechanism and a pair of rotary actuators to facilitate vertical and rotational movement of the arm assembly and the spray-head assembly.
