Device for the sandblasting of small surface regions

An attachment for the sandblasting of small surface regions of the surface (32) to be worked is fitted onto the nozzle (16) of a compressed-air gun. Its injector pipe (15) leads through the wall of a bend (24) and carries horizontally the air/sand-mixing and -discharging pipe (18), which ends at a distance (A2) from the surface (32) and is surrounded by a collecting pipe (28) with a sealing collar (30). The injector sand suction pipe (20) leads through the downward-pointing end (24.3) of the bend into the sand-collecting and -storing container (35) which has an air outlet screen (37) and contains the sand supply at the bottom. Small rust stains and the like can be easily cleaned and blown out. The rebounding sand passes back into the sand-storing and -collecting container (35) in the direction of the arrows (48, 49). ...
