Heading machine with function of preventing drifting of machine body

The heading machine with the machine body drift prevention function comprises a machine frame, a walking mechanism, a cutting part, a left drilling machine and a right drilling machine, the walking mechanism is composed of bottom beams arranged on the two sides of the bottom of the machine frame, a hydraulic motor and a crawler belt, the upper sides of the bottom beams are fixed to the machine frame, the crawler belt is located on the periphery of the bottom beams, and the hydraulic motor is fixed to one end of each bottom beam. The hydraulic motor is used for driving the crawler to rotate; the anti-drifting device is characterized in that a transverse anti-drifting supporting beam is fixed to the outer side face of the bottom beam, and the outer end of the anti-drifting supporting beam is used for abutting against the side wall of a coal mine tunnel. According to the heading machine with the machine body drifting prevention function, the outer ends of the drifting prevention supporting beams abut against the
