Vacuum system for pavement grooving machine

摘要

A one-piece blade shroud and vacuum duct system for removing a water and swarf slurry from a pavement grooving site includes an adjustable intake nozzle for directly receiving the slurry hurled by the rotating blades of a pavement grooving machine. Only two nozzles are used in order to simplify the vacuum ducting and to improve the efficiency of the system. By disposing a water jet assembly within the blade shroud, efficiency is further increased.
