Anti-gushing structure of screw conveyor for shield construction

The invention relates to an anti-gushing structure of a screw conveyor for shield construction, which comprises a belt conveying device, dovetail baffles arranged on two sides of the belt conveying device, a shield screw conveyor gate right opposite to the belt conveying device, and a guide cabin formed by welding an inclined bottom plate, a rear plate and two side plates, the top and the front portion of the guide cabin are open, a front opening of the guide cabin faces the conveying direction of the belt conveying device, a top opening of the guide cabin is connected with a gate of the shield screw conveyor, triangular plates are welded to two side plates of the guide cabin, and the guide cabin is fixed to the dovetail baffle through the triangular plates in a welded mode. A leather curtain is arranged at the front opening of the guide cabin; the top of the leather curtain is fixed; by adopting the technical scheme, muck and/or mud falls into the guide cabin through the gate of the shield screw conveyor, th
