In this structure, the right-hand member of the first air intake tube and the second air intake tube is designed with sealing ring.
In this structure, the outer rim place of the first air intake tube, the second air intake tube and chimney fan is designed with pricks hoop.
Advantageous effect of the present invention is: because this structure of the present invention, so use advantage of the present invention: 1, casing adopts the structure of hemispherical dome, the air channel airflow design, and very little of windage can keep the smoothness of ventilating.
2, cost performance of the present invention is high, and long service life adopts sheet iron to make, and is not fragile.
3, the linkage structure of sealing, in the gear housing, the dust that is contained in the pressure wind that blower fan is blown is isolated in the outside of gear housing, has reduced the probability that transmission system breaks down with grease seal first gear and second gear.
4, use under the situation of the present invention, more can be very reliably during ventilating fan, effectively change automatically, realized the target of automatic conversion of two blower fan dual power supplies of whole boring head.Guaranteed the reliable air feed of boring head.
5, reasonable in design of the present invention is convenient to hang, installs, uses, is safeguarded; Volume is little, has practiced thrift the space in tunnel, helps promoting transportation and ventilation.
