FIELD: dredgers or soil-shifting machines adapted for trenchless underground service line laying.
SUBSTANCE: device comprises tubular vessel connected with percussion mechanism by means pf fastening unit. Percussion mechanism body includes two parts having spherical support surfaces and connected with spacing-guiding member. Fastening unit includes two bushes of annular cylindrical shapes. Each bush is provided with axial spherical orifice adapted to receive spherical support surfaces of percussion mechanism body parts. Cylindrical bush surfaces are secured to inner vessel surface.
EFFECT: increased operational efficiency and service life, prevention of percussion mechanism body defection and simplified structure.
