    摘要: A self-propelled drilling rig for boring blastholes and smalldiameter wells is disclosed, said rig comprising a carriage mounted on the frame of an undercarriage and provided with a manipulator carrying a boring tool. The drilling rig is provided with a servomechanism having a hydraulic drive with a reduction gear, which is operatively connected to a longitudinally movable slide valve, and a plate attached to the slide valve and cooperating with a pusher rigidly secured to the jib manipulator.
