2) the cutting tool height for cutting soft rock or soil layer is concordant, and when running into hard rock, cutting tool is very fast because of wearing and tearing or damaged in collision;
3) at hard-soft heterogeneous ground, excavation face less stable, cutter changing difficulty; Because needs frequently change cutter, speed of application is slow.
For first scheme, although hard rock greatly reduces the wearing and tearing of bite and collision, because hobboing cutter exceeds bite about 20 ~ 30mm, compared with the first scheme, hobboing cutter aggravates further at the eccentric wear of soft rock or soil layer, and tool changing is more frequent.
Hobboing cutter due to compound shield tooling setup or hobboing cutter identical with bite setting height(from bottom) exceeds bite about 20 ~ 30mm, and cutter is all installed by fixed pedestal, cannot to highly adjusting, this easily causes in hard-soft heterogeneous ground tool wear serious, reduce excavation efficiency, increase stratum deformation, improve tool changing frequency and construction cost.
Summary of the invention
The purpose of this utility model is exactly the deficiency that will solve above-mentioned background technology; a kind of shield machine cutter being applicable to hard-soft heterogeneous ground is provided; it can make the relative altitude between hobboing cutter and bite adjust; to play the compliance of different cutter to Different Strata, and make between different cutter, to play the effect given mutual protection.
The technical solution of the utility model is: a kind of shield machine cutter being applicable to hard-soft heterogeneous ground, it comprises the multiple knife combinations be arranged on cutterhead, described knife combination comprises at least one hobboing cutter and at least one bite, it is characterized in that: the axle portion of described hobboing cutter is provided with for detecting the sensor whether it is in rolling condition, described hobboing cutter rear portion is fixedly mounted on cutterhead, described bite rear portion is arranged on cutterhead by the pedestal with hydraulic telescopic device, and described pedestal can be axially movable along shield machine.
Preferably, described knife combination comprises a hobboing cutter and two rankings in the bite of described hobboing cutter both sides.
A kind of shield machine cutter being applicable to hard-soft heterogeneous ground of the present utility model, the sensor that cutter shaft portion installs can detect hobboing cutter and whether be in rolling condition, and the height that cutter head panel given prominence to by bite can regulate within the specific limits, when cutter is in soft rock or texture stratum, the height of bite is higher than hobboing cutter, now utilize bite to excavate, and hobboing cutter is shielded, to reduce the eccentric wear to hobboing cutter; When cutter runs into ground consisting of hard rock, the height of hobboing cutter, higher than bite, now utilizes hobboing cutter to break rock, and shields to bite, prevent bite damaged in collision and wearing and tearing.The utility model adapts to hobboing cutter and the bite of Different Strata driving needs by configuration simultaneously on cutterhead, effectively can reduce the wearing and tearing of cutter in hard-soft heterogeneous ground, reduce number of changing knife, improve drivage efficiency.
