[0021] Step 1: Install the hexagonal chassis on the coal mine ventilation equipment. The air generated by the coal mine ventilation equipment is discharged along the air inlet pipe, telescopic pipe, air outlet pipe, hollow disc and several sector baffles; successively adjust the inclination angle of the hexagonal collar through the first motor, the second motor and the third motor to adjust the air outlet direction of the air outlet pipe.

[0022] Step 2: Under the driving action of the first motor, the motor shaft of the first motor drives the first gear to rotate synchronously. The first gear meshes and drives the first gear ring, the first sleeve, the first collar and the first L-shaped swing arm to rotate along the air inlet pipe.

[0024] Step 4: Under the driving action of the third motor, the motor shaft of the third motor drives the third gear to rotate synchronously. The third gear meshes and drives the third gear ring, the third sleeve, the third collar and the third L-shaped swing arm to rotate along the second sleeve. Under the hinge action between the third L-shaped swing arm and the bending swing arm, drive the hexagonal collar and the air outlet pipe to tilt towards the corresponding side.

[0025] Step 5: Under the driving action of the fourth motor, the motor shaft of the fourth motor drives the fourth gear to rotate synchronously. The fourth gear meshes and drives the arc-shaped gear ring and the rotating ring to rotate slightly along several limit pin shafts.

[0026] The fixed ear seat on the rotating ring drives the sector baffle to rotate along the fixed ring through the hinge connecting rod, so that several sector baffles are unfolded in a divergent shape to adjust the air volume of the air outlet pipe.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. In the present invention, the inclination angle of the hexagonal ring is adjusted by three motors, so that the air outlet direction of the air outlet pipe can be accurately changed, so that the air outlet direction of the air outlet pipe can be adjusted and optimized according to actual conditions, thereby enabling the wind flow to flow more smoothly in the lane, reducing the energy loss of the wind flow on obstacles such as the lane wall;

[0029] 2. In the present invention, the divergent expansion design of the fan-shaped baffle makes ventilation adjustment more flexible. The air volume of the air outlet pipe can be quickly adjusted according to the mining progress and the changes of the ventilation system to adapt to different ventilation conditions. The air volume can be accurately distributed according to the actual ventilation needs of different working areas in the coal mine, ensuring that each work location has a suitable air volume, thereby effectively diluting the concentration of harmful gases such as gas;

[0030] 3. By setting up multiple motors to work together, the manual workload is reduced to the greatest extent, the operation is simple, time-saving and labor-saving, and is not limited by the miners' operating proficiency;
