Soil cabin structure of shield machine

Abstract

The invention discloses a soil cabin structure of a shield machine. A drive motor is fixedly installed at the proper position of the lower end of the soil cabin wall, the side facing a soil cabin, of the drive motor, is connected with a drive shaft, and a stirring wing is fixed in the peripheral direction of the drive shaft. Therefore, when fully stirred muck is fed into the soil cabin through cutting, the drive motor can be started and drives the stirring wing to rotate and stir the muck through the drive shaft. Mud cake forming is thoroughly prevented, the flowing and discharging speed of the muck is further improved, and the working efficiency is high. In addition, the soil cabin structure of the shield machine further has the advantages of being low in manufacturing cost, easy to install, convenient to operate and the like.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to an earth cabin structure of a shield machine. Background technique [0002] When the earth pressure balance shield machine is carrying out tunnel excavation construction, the soil cut by the cutter head will accumulate in the middle and lower part of the soil cabin after entering the soil cabin, and then sent out by the screw conveyor to the belt conveyor inside the shield machine. If the muck accumulated in the soil tank is not fully stirred, mud cakes will easily form, which will affect the discharge of muck. In severe cases, it will affect the quality of construction and the progress of construction. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies in the background technology and provide a soil chamber structure of a shield machine. The soil chamber structure of this shield machine is ...
