The invention provides a shield tunneling machine with a bin-opening cutter-changing ventilation system. The shield tunneling machine with the bin-opening cutter-changing ventilation system comprisesa shield tunneling machine body, a screw conveyor, a cutter head, a cutter head supporting arm, a man bin, an isolation wall and a soil bin. The shield tunneling machine with the bin-opening cutter-changing ventilation system also comprises a cutter-changing device and a ventilation device. The cutter-changing device comprises a box body, a first telescopic mechanism, a second telescopic mechanism, a third telescopic mechanism and a cutter clamping mechanism; the ventilation device comprises an air compressor, an air delivery pipe, an air outlet pipe and a silencer. Noise generated by the aircompressor is eliminated while the temperature and the air in the soil bin are improved, a worker is assisted in replacing a cutter, the working efficiency is improved, and the life safety of the worker is protected.
