Problems solved by technology
Due to the long slag discharge channel, the lubricant consumption is too large during the slag discharge process, resulting in increased friction between the slag and the screw shaft, screw blades and cylinder in the second half, which is extremely easy to cause slag blockage

The invention discloses a screw structure, comprising a helical shaft, a helical blade arranged on the helical shaft, and a lubricating fluid passage arranged along the joint of the helical blade andthe helical shaft, and a lubricating fluid ejection outlet through which lubricating fluid flows out is arranged on the lubricating fluid passage. Compared with the prior art, the screw structure provided by the invention is applied to a screw conveyor, a lubricating fluid film can be formed between residue soil and the spiral shaft, between the residue soil and the spiral blade and between the residue soil and the inner wall of a barrel, thereby reducing the friction force between the residue soil and the spiral shaft, between the residue soil and the spiral blade and between the residue soiland the barrel during the residue soil discharge process, thus the residue soil can be smoothly and efficiently discharged, the engineering accident caused by the residue soil clogging is avoided, and the construction efficiency and the construction quality are improved. The invention also relates to a screw conveyor and a tunneller, which also have the aforementioned beneficial effects.
Description
technical field [0001] The application relates to the field of special mechanical equipment for tunnel construction, in particular to a screw structure. The application also relates to a screw conveyor and a boring machine. Background technique [0002] my country is one of the largest roadheader manufacturing bases and application markets in the world. The use of the roadheader is accompanied by the generation of dregs and waste. If the dregs are not discharged in time, engineering accidents such as clogging of dregs and damage to the mechanical structure of the roadheader will be caused, which will directly affect the slag discharge of the screw conveyor and increase the driving torque load. , slow tunneling speed and other related issues. In the construction process of the roadheader, the screw conveyor is generally used for slag discharge, but due to the high friction between the slag and the screw shaft, screw blade and cylinder, the slag discharge efficiency of the or...
