AI Technical Summary
Technical Problem
Existing slurry shield vibrating screens are ineffective in separating mud in cohesive soil layers, leading to screen plate blockage, ineffective mud separation, environmental pollution, and construction difficulties.
Method used
Perforated drive chain plates are used instead of screen plates to separate cohesive soil from muddy water. Large pieces of cohesive soil are transported to the slag yard for storage via the drive chain plates, while the water flows away directly, thus improving the separation effect.
Benefits of technology
It effectively separates cohesive soil from muddy water, reduces the risk of clogging, shortens the construction period, and avoids environmental pollution.

Abstract
The invention discloses a slurry shield tunneling full-section cohesive soil layer vibrating screen, and relates to the field of shield construction equipment, the slurry shield tunneling full-section cohesive soil layer vibrating screen comprises a screening machine base, a screening box, a vibration exciter and an elastic connecting mechanism, the screening box is installed on the screening machine base through the elastic connecting mechanism, and the vibration exciter is arranged on one side of the screening box; a transmission chain plate, a driving chain wheel, a driven chain wheel and chain wheel shafts are arranged in the screen box, the chain wheel shafts are rotationally arranged at the front end and the rear end of the screen box, the front chain wheel shaft is higher than the rear chain wheel shaft, the driving chain wheel is installed on the rear chain wheel shaft, and the driven chain wheel is installed on the front chain wheel shaft. One end of the rear chain wheel shaft penetrates through the screen box and is fixedly connected with an output shaft of the first motor, the transmission chain plate is annularly arranged on the driving chain wheel and the driven chain wheel in a surrounding mode, a plurality of drainage holes are formed in the transmission chain plate, and the transmission chain plate is connected with the driving chain wheel and the driven chain wheel in a meshed mode. The separation effect of the vibrating screen is improved, and slurry is prevented from flowing into a slag field after the vibrating screen is blocked.
