Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a screw conveyor device for a tunneling machine. Background Art

[0002] When using an earth pressure balance tunnel boring machine for tunnel construction, the screw conveyor is required to discharge the slag during excavation, which is one of the indispensable key components of the tunnel boring machine. The screw conveyor is arranged obliquely at the front of the tunnel boring machine, and the front end extends into the lower part of the soil bin. The slag is transported to the belt conveyor through the angle between the screw conveyor and the tunnel boring machine, and then discharged out of the tunnel.

A large amount of accumulated debris causes blockage of the discharge pipe, which results in unsmooth discharge of the screw conveyor and easy blockage. At the same time, when the screw conveyor is blocked, it needs to be disassembled as a whole, which consumes a lot of manpower and material resources, greatly reduces work efficiency, and is very inconvenient to use.
