Integrated steam drill

An integrated steam drill, comprising a drill rod;

• wherein the drill rod comprises a drill bit (1), and a steam generator (2) and an air-liquid mixing assembly (3) are sequentially provided at positions of the drill rod facing toward the drill bit (1) in that order;
• wherein the air-liquid mixing assembly (3) comprises a liquid storage component (31) with a liquid storage chamber (310), and an air pipeline (32) configured for connecting an external high-pressure air source;
• the air pipeline (32) is connected to an atomizer, an air-liquid mixing chamber (93) connected to an upstream and a downstream of the air pipeline (32) is defined inside the atomizer, and the air-liquid mixing chamber (93) is connected to the liquid storage chamber (310);
• the atomizer is configured to atomize water stored in the liquid storage chamber (310) to thereby obtain atomized water droplets for flowing into the air-liquid mixing chamber (93) and mixing with high-pressure air in the air pipeline (32) to form an air-liquid mixture;
• wherein the steam generator (2) is internally provided with a coil pipe (21) and a combustion mechanism (4);
• an inlet end of the coil pipe (21) is connected to an outlet end of the air pipeline (32);
• the combustion mechanism (4) faces toward the coil pipe (21) and is configured for connecting an external gas source;
• and the combustion mechanism (4) is configured to heat the air-liquid mixture in the coil pipe (21) into steam by burning gas;
• and
• wherein an end of the drill bit (1) is connected to the steam generator (2), and a nozzle (11) is disposed on another end of the drill bit (1);
• and the nozzle (11) is connected to an outlet end of the coil pipe (21).
