Knife and side hobboing cutter, level-one cutterhead are equipped with level-one slag notch.
The central hob is located at the center of level-one cutterhead, and side hobboing cutter is located at the edge of level-one cutterhead, and positive hobboing cutter is located at
Between central hob and side hobboing cutter, central hob and positive hobboing cutter are installed perpendicular to cutterhead face, and side hobboing cutter favours the installation of cutterhead face.
The second level cutter includes the edge doctor on second level cutterhead, and second level cutterhead is equipped with second level slag notch.
The edge doctor is located at the edge of second level cutterhead, and outstanding cutter favours the installation of cutterhead face.
The level-one cutterhead is panel type.
The second level cutterhead is plate spoke.
Seriously perplex hard rock tunnel for a long time compared with prior art, the utility model has the beneficial effects that solving
The problems such as cutterhead geological adaptability of construction is poor, super-large diameter drivage efficiency is low, knife disc tool limitation cutterhead digging diameter, foundation
Geological adaptability is theoretical, and level-one cutterhead uses hard rock hob allocation plan, and second level cutterhead is using outstanding cutter as broken rock cutter
Allocation plan so that two-stage cutterhead being capable of separately adjustable driving speed in tunneling process.Due to using two-stage cutter disc system
Split-type design substantially increases the geological adaptability of super-large-diameter shield cutterhead, improves the effective of knife disc tool and uses the longevity
Life, drivage efficiency and economy.
