To effectively improve the wear resistance performance and service life of the scraper conveyor middle groove,optimize design of the middle groove structure is conducted.Based on the theory of non smooth wear resistance,a 3D-finite element model of the scraper conveyor middle groove is established using SolidWorks and ANSYS software,and the contact stress of the middle groove in smooth/non smooth state is simulated and studied.The results show that setting the groove structure on the middle plate surface of the middle groove can significantly improve friction and wear phenomena,and enhance wear resistance;the optimal parameters for the groove are a diameter of 2 mm,a depth of 5 mm,and a transverse and longitudinal spacing of 50 mm.The maximum contact stress value is 353.631 MPa,and the decrease reaches 23.78％.The new structure of the middle groove is applied to the SGB620/80T scraper conveyor at the 8311 working face of Tongxin Coal Mine.The structure and operation of the new structure of the middle groove are stable,and the service life is doubled.The improved design of the groove in the middle groove structure of the scraper conveyor can effectively improve its wear resistance performance,extend its service life,and achieve significant economic and safety benefits.
