Abstract

The invention discloses a crushing and grinding machine for a shield machine, which solves the problems of easy blockage and low construction efficiency of a slurry shield machine or a slurry pipe jacking machine in the prior art when slurry is discharged. The invention comprises a support shell, wherein the front end of the support shell is provided with a slurry inlet and an observation hole, the rear end of the support shell is provided with a driving unit, the lower part of the support shell is provided with a slurry outlet, a crushing mechanism and a grinding mechanism are arranged in thesupport shell, and the crushing mechanism and the grinding mechanism are connected with the driving unit. The invention utilizes the crushing mechanism to crush pebbles step by step to ensure that the diameter of all the stones entering the slurry outlet is smaller than the maximum passing diameter of a slurry discharge pump, and the stones crushed by a conical crushing disk enter the grinding mechanism to re-grind the stones so as to ensure that the stones do not get stuck and avoid blockage.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to a crushing and grinding machine for shield tunneling. Background technique [0002] When the small-diameter mud-water shield or mud-water pipe jacking machine is constructed in the pebble formation, it is limited by the passing particle size of the slurry pump. The excavated pebbles may be larger than the maximum passing particle size of the slurry pump, and must be treated before passing the slurry. The pump is discharged, otherwise the stone stuck in the pump will pose a serious construction risk. [0003] The traditional method is generally to install a filter device before the slurry discharge pump to filter large pebbles, but small pebbles are easy to stay in the filter device while filtering large pebbles, causing pipeline blockage and slag cannot be discharged, which in turn causes The pressure of the excavation face suddenly rises, causing the groun...
