Description

Technical Field

[0001] The utility model relates to the technical field of ventilation devices, in particular to a ventilation device for mining which is easy to adjust. Background Art

[0002] Mining operations require digging tunnels. Since the tunnel has only one opening, the air inside is difficult to circulate, and ventilation devices are needed to promote the flow of air inside, maintain the air quality inside, or purify the air inside.

[0003] Most of the existing ventilation devices do not have an adjustment structure, which makes it difficult to change the position and orientation of the ventilation devices during actual use, affecting the convenience of the ventilation devices during actual use. In addition, during use, the dustproof net surface of the existing ventilation devices will absorb dust, causing the air duct of the ventilation devices to be blocked, resulting in the ventilation devices being unable to be used normally, affecting the effect of the ventilation devices during actual use. For this reason, we propose a mining ventilation device that is easy to adjust. Utility Model Content
