BLASTING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a blasting machine which easily fits a casing for preventing the scattering of an abrasive material by sealing even to parts largely varied in size such as angle parts in the outer wall or inner wall of a building wall surface. SOLUTION: This blasting machine performs the surface treatment of a surface S1or S2to be treated by injecting the abrasive material to the surface S1or S2from an injection nozzle within a sealed hood 2 opened toward the surface S1or S2. This blasting machine comprises a tension plate 22a having a shape according to the surface S1or S2and mounted with a rubber packing 23 on the surface S1or S2side, a universal joint 25 for connecting and separating the tension plate 22 to the sealed hood 2, and a rubber sheet 26 for blocking the space between the tension plate 22 and the sealed hood 2.
