The utility model relates to a tapping device, particularly an automatic slag tapping machine for magnesium extraction, which is used in a reduction furnace for magnesium metallurgy. The utility model comprises a longitudinal horizontal-shifting vehicle, a transversal horizontal-shifting vehicle which is installed on the longitudinal horizontal-shifting vehicle and can do horizontal movements in the transversal direction, and a screw tapping head which is installed on the longitudinal horizontal-shifting vehicle. The utility model is characterized in that the screw tapping head is composed of a hollow shaft and screw blades fixed on the hollow shaft, and the screw blades have a screw water leg type structure. Inlet openings and outlet openings are fixed on the hollow shaft and the screw blades, and the head part of the tapping head is positioned by a bracket fixed on the longitudinal horizontal-shifting and a roller which is installed on the bracket and can move upwards and downwards. A high-pressure air tube is arranged in the hollow shaft, one end of the high-pressure air tube is communicated with an air-jetting hole at the head part of the hollow shaft, and the other end extends out of the hollow shaft and is connected with an air inlet tube. The tail of the tapping head is connected with a power part which is installed on the transversal horizontal-shifting vehicle and can drive the transversal horizontal-shifting vehicle to rotate. The utility model has the advantages of high efficiency, good using effect, reliable operation, etc.
