Zusammenfassung:	The utility model provides a rotary drilling rig. The rotary drilling rig comprises an engine assembly, a rotary table assembly, a main winding assembly, a cab assembly, a diesel tank assembly and a heat radiator assembly, wherein the engine assembly, the rotary table assembly, the main winding assembly, the cab assembly, the diesel tank assembly and the heat radiator assembly are all arranged on a chassis of the rotary drilling rig, an interval is formed between the main winding assembly and the rotary table assembly, and an air outlet of the heat radiator assembly right faces the interval. The rotary drilling rig improves heat dissipation efficiency of the heat radiator assembly by leaving a channel for the heat radiator assembly to discharge hot air in the layout.
