Abstract：In response to the structural failure,deformation,and insufficient stability of the scraper connection caused by factors such as wedge effect in the application of scraper slag cleaning conveyor in adverse geological engineering sites,an innovative method was proposed by combining on-site measurement and theoretical analysis to add limit components to the driving end and improve the segmented connection structure of the machine groove,in order to suppress the dynamic fluctuation of the chain and reduce the stress concentration of the machine groove.The improved equipment was designed in a modular manner,which is convenient for mining TBM matching.The on-site application test results are good,and the deformation of the scraper did not occur again.The connection failure of the machine groove was eliminated,improving the conveying efficiency and reducing the failure rate of the scraper slag cleaning conveyor.This provides corresponding reference for the application of scraper slag cleaning conveyor in adverse geological conditions.
