Abstract

The invention discloses a reverse circulation drilling machine, comprising a rack, the front side and the rear side of the left side of the rack are fixedly connected with main frame assemblies through main frame pin shafts. The surface of each main frame pin shaft is sleeved by a main frame pin shaft check ring. The left side of the top of the rack is fixedly connected with an oil cylinder body through a first oil cylinder body pin shaft. The top end of the oil cylinder body is fixedly connected with the right side of the main frame assemblies through a second oil cylinder body pin shaft. A power assembly is fixedly connected to the upper portion of the interior of the rack, the front portion of the left side of the power assembly communicates with a slag discharging pipe, a fixing columnis fixedly connected to the rear portion of the bottom of the main frame assembly, a fixing clamping jaw is fixedly connected to the surface of the fixing column through a support, and transmission frames are fixedly connected to the front side and the rear side of the rack. The invention relates to the technical field of drilling machines. According to the reverse circulation drilling machine, the main frame assemblies are used for drilling in a vertical lifting mode, the pressurization mode is changed, overhead crane suspension and drill rod self-weight pressurization are changed into powerhead vertical pressurization, and the drilling perpendicularity is improved.
