[0009] Preferably, the driving plate is meshingly connected with the driving gear via a gear block.

[0010] Preferably, the lever is slidably connected to the frame through the adjustment window.

[0011] Compared with the prior art, the beneficial effect of the utility model is that when the ventilation volume in the adjustable coal mine wind window needs to be adjusted, it is only necessary to push the driving plate to move by means of the lever, and the driving plate pushes the driving gear to rotate through the gear block, and the rotating driving gear will drive the wind shield plate to rotate synchronously through the second horizontal axis, making it convenient for the wind shield plate to rotate and tilt to different opening angles, thereby facilitating the purpose of adjusting the ventilation volume.
