GRINDING/SWEEPING SYSTEM NOZZLE HEAD AND GRINDING/SWEEPING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a grinding/sweeping system nozzle head capable of grinding and sweeping the side wall face of a narrow part such as a gap of a bridge expansion device in a grinding/sweeping system that jets a grinding/sweeping material to a grinding/sweeping object face to grind and sweep the same and sucks and recovers jetted grinding/sweeping material and dust generated from the grinding/sweeping object face.SOLUTION: This system has a base end part 2 to which a hose for supplying a grinding/sweeping material is connected, a tip part 3 inserted into a narrow part, the tip part 3 having an opening 7 opened toward the side wall face in a narrow part which is a grinding/sweeping object face, a jet nozzle 6 that jets the grinding/sweeping material supplied from the hose from the jet port 6a toward the interior of the tip part 3, a reflection plane 8 that reflects the grinding/sweeping material jetted from the jet port 6a of the jet nozzle 6 toward the opening 7, and a suction recovery port 9 to which a hose for sucks and recovers the grinding/sweeping material and dust generated from the grinding/sweeping object face is connected, the suction recovery port 9 provided in a position closer to the base end part 2 than to the jet port 6a of the jet nozzle 6.SELECTED DRAWING: Figure 2
