A multi-stage adjustment device will be installed inside the ventilation device, which can automatically adjust the interior of the ventilation device according to the situation to achieve better ventilation effect.

[0003] When the ventilation device is used in a mine, it will be affected by the dust in the mine. Since there is a lot of dust when working in the mine, a filter assembly needs to be installed inside the ventilation device to filter the air entering the ventilation device. However, the internal mesh of the filter will be clogged with dust when it is in use. Therefore, a brush plate will be installed outside the filter to clean the filter. However, the dust cleaned by the brush plate will still be sucked into the inside by the fan. In addition, due to the importance of the ventilation device, it is necessary to ensure the normal operation of the ventilation device at all times during work. Therefore, the method of stopping the device and using a brush plate for cleaning cannot meet the requirements of underground mine ventilation. In order to solve this technical problem, the utility model proposes an automatic control device for underground mine ventilation. Utility Model Content
