Integrated ventilation and dust removal equipment for tunnel construction

Abstract

This utility model discloses an integrated ventilation and dust removal device for tunnel construction, relating to the field of tunnel construction technology. After the fan is started, the dust-removed gas inside the collection box is extracted through the exhaust nozzle, exhaust pipe, and connecting pipe. The extracted gas is discharged through the exhaust pipe. As the fan continues to operate, dust-laden gas in the tunnel enters the collection box through the air inlet, circulating repeatedly to achieve ventilation inside the tunnel. After the drive motor is started, it drives the drive wheel and the transmission wheels on both sides to perform circular motion. This causes the transmission wheels, drive shaft, and the striking wheels on their circumferential surfaces to perform circular motion. Under the action of the support spring, the inner wall of the screening plate always abuts against the outer wall of the striking wheels, allowing the screening plate to reciprocate vertically inside the collection box. Thus, the dust removal mechanism achieves its purpose.
