Fig. 1 and Fig. 2 are please referred to, Fig. 1 is a kind of signal of specific embodiment of cutter of shield machine provided by the present invention
Figure；Fig. 2 is the side view of the cutter of shield machine shown in FIG. 1.
In a kind of specific embodiment, the present invention provides a kind of cutters of shield machine, for cutting in-situ consolidation
Drain bar and braided fabric, comprising: cutter hub 3, cutter head 2 and cutter head sharp sword 1；The cutter head 2 is embedded in the head of the cutter hub 3, institute
It states cutter head sharp sword 1 to be embedded on the cutter head 2, the height of the cutter head sharp sword 1 is greater than predetermined altitude, the sword of the cutter head sharp sword
Mouth angle α is less than predetermined angular, and the cutter head sharp sword 1 is arranged in three faces, and side is in inverted trapezoidal.
The cutter of shield machine provided by the invention has the cutter head sharp sword 1 higher than cutter head predetermined altitude, and shield machine uses should
When cutter cuts in-situ consolidation drain bar and braided fabric, cutter head sharp sword 1 preferentially cuts the soil body, in advance to the consolidation draining in the soil body
Plate and braided fabric are cut, and cutter head 2 then carries out tear failure driving to the soil body, can cut consolidation draining plate and braided fabric
At the effect of segmentation, the winding of drain bar and braided fabric to cutterhead is reduced, is conducive to consolidation draining plate and braided fabric and dregs
It excludes, improves shield machine drivage efficiency.
The cutter structure is simple, low in cost, and high reliablity is easy to use, and consolidation draining plate is encountered in shield-tunneling construction
Or can ensure that shield machine normally tunnels when braided fabric, the time that construction is shut down is reduced, construction cost is saved, improves construction effect
Rate.
For example, cutting edge angle α≤30 ° of cutter head sharp sword 1, are highly not less than 20mm, are fabricated using steel alloy,
Depth-width ratio 2:1 is embedded on cutter head at inverted trapezoidal soldering, and sharp sword is arranged in three faces, it can be achieved that positive and left and right three-sided cut.Work
During making principle, when shield machine encounters consolidation draining plate and braided fabric in the work environment, the cutting edge angle of the knife is utilized
α, cutter head sharp sword 1 are first advanced into the soil body, by consolidation draining plate cutting section in soil layer, then are broken ground and are struck off by cutter head 2, consolidation draining
Plate and braided fabric are discharged with dregs by screw machine.
In a kind of preferred embodiment, the groove of the head distribution of the cutter hub 3 at a predetermined distance, the cutter head 2
It inlays in the groove.
The cutter head 2 is alloy block, is distributed the groove of three interval 30mm, three pieces of hard alloy blocks on the head of cutter hub 3
Body, which is inlayed to be brazed in the groove, forms cutter head 2, which has certain intensity and wearability, is conducive to cutter to the soil body
Tearing abolish.
