[0002] The slag discharging system is one of the key systems of a shield machine. At present, belt conveyors are mostly used for slag discharging in the equipment section of shield machines. The belt conveyor is generally divided into two major parts: an inclined section and a horizontal section. Since the slag on the inclined section is transported obliquely upward, for some special strata, the surface of the slag is very smooth, and slag slipping often occurs on the inclined section, seriously affecting the slag discharging efficiency and tunneling efficiency.
