The invention provides a swinging arm type calcium carbide furnace discharging machine which mainly comprises a slewing mechanism, a swinging mechanism, a clamping and rotating mechanism and a telescopic mechanism, wherein the swinging mechanism is arranged on the slewing mechanism; the telescopic mechanism is arranged on the slewing mechanism; the clamping and rotating mechanism is arranged in the telescopic rod of the telescopic mechanism; a corresponding tool rod is clamped by the clamping and rotating mechanism, so that the corresponding functional operations such as drilling, burning through, punching, plugging and maintaining of a burner are finished. The machine is fully mechanized equipment, the condition that the human body works in a severe high-temperature environment for a long time can be avoided, the potential safety hazards are reduced, the condition that the normal production is influenced because the burner ascends to a table, the furnace bottom is elevated and the equipment is melted to cause loss is avoided during normal operation, the discharging operation time is reduced, the thermal loss is reduced, the quality is stabilized, the yield is increased, and the calcium carbide furnace lifting step is stabilized.
