Embodiment Construction
[0022] Below in conjunction with accompanying drawing, the present invention will be further described:
[0023] like figure 1 , figure 2 As shown, a shield cutterhead system with a super large diameter for soft and hard uneven formations includes large cutterheads, medium cutterheads, small cutterheads, spokes, panels, hobs, cutters, leading knives, center knives, stirring Rods, reducers, hydraulic motors, power transmission devices, shields, screw excavation devices. It is characterized in that the front cutterhead structure of the shield machine consists of nine cutterheads distributed in a spatially staggered structure, including large cutterheads, medium-sized cutterheads, and small cutterheads. The first stage of the cutterhead structure is a medium-sized cutterhead, and one medium-sized cutterhead is located at the center of the shield cutterhead structure; the second stage of the cutterhead structure is a small cutterhead, and there are four small cutterheads along ...
