Abstract: The middle transfer device of the belt conveyor in the dark inclined shaft is subject to space limitation and unreasonable design, which leads to blocking, spreading and dust pollution problems, thus establishing the mechanical model of the transfer material, using the discrete element method to simulate and compare the material transfer process of three working conditions, analyzing the discharge efficiency, conveying volume and material flow trajectory characteristics, designing a middle transfer device and summarizing the design method, and using the printing technology to pre-design and manufacture the transfer device. The design method is summarized, and the transfer device is pre-designed and manufactured by using printing technology. The results show that the middle transfer device designed by using the simulation speed, conveying volume and material trajectory has no blocking and spreading of material in the transfer process, And the design method constantly improve, optimize the structure, reduce the impact of the material on the central transfer device and conveyor belt, extend the life, with practical engineering application value.
