PURPOSE: An automatic air blasting machine for a subway is provided to rapidly and safely blast air through air blasting information programmed depending on the time of each subway and climate environment. CONSTITUTION: An automatic air blasting machine (2) for a subway comprises a robot blasting unit (200), a lower blasting unit (300), a supply/exhaust unit (400), and a controller. The robot blasting unit blasts fine dust by moving an injection port to a target area of a subway (4) and jetting compressed air to the target area. The lower blasting unit moves along the bottom of the subway to blast fine dust. The supply/exhaust unit supplies compressed air to the robot blasting unit and the lower blasting unit and exhausts air having the fine dust to the outside. The controller senses the position of the subway and determines where the blasting units are operated. |
