Summary:The utility model provides a quarrying device of a shield tunneling machine. The quarrying device comprises a screening unit and a quarrying unit which are connected. A slurry inlet and a slurry outlet are formed in the screening unit box body, a stone outlet is formed in the end, away from the slurry inlet, of the screening unit box body, and a hobbing type screening conveying mechanism with a synchronous transmission function is arranged in the box body. In addition, silt, stones and clay blocks which are smaller than the screening hole diameter can be discharged from the slurry dischargingopening. The stone storage unit comprises a stone collecting channel, a stone storage box and a stone collecting gate and has the functions of storing and discharging large-particle-size slag stones.According to the quarrying device, the slag screening efficiency is improved to the maximum extent, sufficient screening is ensured, and efficient quarrying is achieved; the stone storage space is increased to the maximum exte
