[0002] Nowadays, the use of dust collectors is more common in the field of tunnel construction. During the tunnel construction process, a large amount of dust will be generated, which will affect the normal work of the workers and also bring health hazards. In order to facilitate the dust removal in the tunnel, dust collectors are usually used to assist.

[0003] In application number: CN202320949915.1, a dust collector for tunnel construction is disclosed. The dust collector for tunnel construction drives the pallet to adjust up and down through a lifting component, and drives the air intake bell pipe to adjust the height through the pallet, thereby realizing the height adjustment processing of the dust collector. The air sucked into the intake pipe is sprayed and dusted through the setting of the spray component.

[0004] However, the height of the fixed back plate of the device is high and fixed and cannot be adjusted. Some shorter tunnels do not support the entry of the fixed back plate, and although the air intake horn of the device can be adjusted in height, if it is adjusted to a high position, dust at lower places cannot be inhaled, and if it is adjusted to a low position, dust at higher places cannot be inhaled. It is necessary to repeat the dust removal work many times to completely remove the dust in the tunnel, which increases the workload and has low dust removal efficiency. Therefore, a tunnel construction dust removal device is proposed, which can adjust the height of the blowing fan to adapt to tunnels of different heights, so that the blowing fan can blow the dust at high places down to the entrance of the low air intake hood, so as to achieve the effect of simultaneous dust removal at high and low places.
