Abstract

The utility model provides an air volume adjusting device for a mine roadway. The air volume adjusting device comprises an air bag module, an inflation module, a fixing module, a master control module and a sensor module. The airbag module is formed by splicing a plurality of airbags; the inflating module is used for inflating and deflating the air bag; the fixing module comprises a first stand column, a second stand column, an upper guide rail, a lower guide rail and guide wheels. The left and right sides of the airbag module are respectively fixed with the first upright and the second upright to form an air door; the upper and lower sides of the airbag module are respectively fixed with the upper and lower guide rails; the upper and lower ends of the first upright post are fixed with the left side of the guide rail; guide wheels are arranged at the upper end and the lower end of the second stand column and can drive the second stand column to move left and right along the guide rails so as to drive the air door to open or close and achieve roadway ventilation and closing. Ventilation adjustment can be conducted on the mine roadway, and the roadway can be effectively closed.
