Urban road and traffic engineering road drilling machine

The utility model relates to the technical field of engineering road drilling machines, and discloses an urban road and traffic engineering road drilling machine which comprises a main body mechanism, an air suction mechanism is arranged on the surface of the main body mechanism, a connecting mechanism is arranged on the right side of the main body mechanism, and the main body mechanism comprises a supporting frame. A supporting column is fixedly connected to the bottom of the supporting frame, a supporting sliding rod is slidably connected to the inner wall of the supporting frame, a moving column is fixedly connected to the right side of the supporting sliding rod, and a supporting sleeve is fixedly connected to the end, away from the moving column, of the supporting sliding rod. A large amount of dust and broken stones are splashed at the moment when the drill bit is used for drilling, the broken stones can be effectively prevented from damaging the drill bit through the connection of the threaded connecti
