The invention discloses a machine-mounted type multipurpose anchor rod drilling machine, which comprises a drilling machine and further comprises a fixing disc, a traversing mechanism, a telescopic mechanism and a swing arm device, wherein the traversing mechanism is arranged on the fixing disc, and the telescopic mechanism comprises a telescopic outer arm, a telescopic inner arm and a telescopic arm oil cylinder. The telescopic outer arm is hinged to the traversing mechanism, one end of the telescopic inner arm is arranged in the telescopic outer arm and is connected with the telescopic outer arm through the telescopic arm oil cylinder arranged in the telescopic outer arm, and the other end of the telescopic inner arm is connected with the drilling machine. One end of the swing arm device is hinged to the traversing mechanism, and the other end of the swing arm device is hinged to the telescopic outer arm. The machine-mounted type multipurpose anchor rod drilling machine can carry out flexible positioning adjustment according to the contour of a small chamber, performs anchor rod hole construction, drills holes quickly and accurately, and fundamentally eradicates potential safety hazards caused by the fact that quality of an anchor rod supporting system cannot meet design requirements due to inconvenience of anchor rod hole construction.
