Acute angle protrusion drives two semicircle crushing cutters to carry out rotation and breaks towards the interior positive side for wearing down cutterhead 500 in the cutterhead of work
When broken, when the torsion and main crushing cutter 501 that the both ends of two semicircle cutters generate when rotating to main crushing cutter 501 are crushed
The stress of generation carries out effective component work, improves main crushing cutter 501 and carries out broken to gravel and soil and excavate
Efficiency, while reducing abrasion of the main crushing cutter 501 in tunneling process.
Further, the broken notch 503 is irregular quadrangle, and the depth of the broken notch 503 is each
The half of semicircle shape crushing cutter thickness, and broken notch 503 is provided on the inner sidewall of main 501 arc of crushing cutter,
When the rotation of main crushing cutter 501 is broken, gravel and soil can be impinged upon in the inner cavity of broken notch 503, to gravel and soil
Impact force buffered, while the cavity wall that the turning of broken notch 503 and broken notch 503 are formed, in main crushing cutter 501
Gravel and soil can be carried out being crushed work again in rotation process, improve and broken completeness is carried out to soil and gravel.
Further, the piecemeal cutter 601 is helical form, and the quantity of the piecemeal cutter 601 is three, described in three
The middle part of piecemeal cutter 601 is overlapped and is welded on the middle part of 600 positive side of center cutterhead, and the cutting face of the piecemeal cutter 601 is
The triangular shape of spiral, in the cutterhead course of work, multiple synchronous rotations of piecemeal cutter 601 tunnel tunnel, make to tunnel
Cheng Zhongke split to gravel layer and is crushed, so that torsion and stress that cutterhead is integrally born in tunneling process are reduced, drop
The wear rate of low cutterhead and cutter.
Further, the outer limited diameter cutter 401, piecemeal cutter 601 and main crushing cutter 501 are located at cutter head of shield machine shell
The equidistant increase of depth of 100 inner cavity positive sides, and outer limited diameter cutterhead 400, the center cutterhead 600 of 100 inner cavity of cutter head of shield machine shell
With the interior equidistant increase of depth for wearing down cutterhead 500 and being located at 100 inner cavity positive side of cutter head of shield machine shell, dug in shield machine belt movable knife disc
During, the disruption elements such as outer limited diameter cutter 401, main crushing cutter 501 and piecemeal cutter 601 carry out substep and are crushed, and break
The gravel and soil of broken generation are broken in outer limited diameter cutterhead 400, the interior staged formed between cutterhead 500 and center cutterhead 600 of wearing down
It is moved in broken chamber, gravel and soil carry out again in knockout process through crushing cutters such as main crushing cutter 501 and piecemeal cutters 601
Broken work.
Further, the outer limited diameter cutterhead 400, center cutterhead 600 and the interior height of projection for wearing down 500 dorsal surface of cutterhead
With outer limited diameter cutterhead 400, center cutterhead 600 and the interior cutterhead 500 that wears down in the cup depth of 100 inner cavity positive side of cutter head of shield machine shell
It is corresponding, export the gravel of broken completion and soil successively through screening leak hole 700, while the export of the staged by being formed
Chamber, collision when increasing export between gravel and soil prevent the congestion in export cavity in gravel and soil export process.
Further, the screening leak hole 700 is divided into three groups, and screening leak hole 700 described in three groups is respectively distributed to interior wear down
The middle part of cutterhead 500 and center cutterhead 600, interior cutterhead 500 and the center cutterhead 600 of wearing down pass through screening leak hole 700 respectively
It connects with the inner cavity of cutter head of shield machine shell 100, wherein being located at interior wear down screens leak hole 700 in cutterhead 500 and center cutterhead 600
Diameter be sequentially reduced, and on center cutterhead 600 screen leak hole 700 internal diameter be sequentially reduced from outside to inside, the screening leak hole
700 are dislocatedly distributed with main crushing cutter 501, piecemeal cutter 601, welding plate 602, and in broken work, gravel and soil can be in ranks
It is exported in ladder type crusher chamber through various sizes of screening leak hole 700, meanwhile, because the crushing cutter that piecemeal cutter 601 forms is close
The crushing teeth at middle part is more concentrated, be crushed the gravel for more thoroughly making different degree of crushing and soil can also from different location and
It is exported in various sizes of screening leak hole 700, increases the gravel of broken completion and the export efficiency of soil.
Working principle:
When the shield machine belt movable knife disc of work is operated: the cutter head of shield machine shell 100 of rotation drives outer limited diameter cutterhead
400, the interior driving toolbox such as cutterhead 500 and center cutterhead 600 that wears down synchronizes driving and broken work；
Level-one driving is crushed: limited diameter cutterhead 400 outer first and outer limited diameter cutter 401 are tunneled and are broken to tunnel periphery
Broken, the end of tunneling process China and foreign countries limited diameter cutter 401 carries out the headwork of sizing, the gravel and soil generated in driving to tunnel
Earth enters through water conservancy diversion sliding slot 402 in the cavity of outer 400 inside of limited diameter cutterhead；
Second level driving is crushed: during cutterhead promotes, center cutterhead 600 drives piecemeal cutter 601 in the middle part of tunnel
It being tunneled and is crushed, the center cutterhead 600 and piecemeal cutter 601 of operating are crushed again after splitting to tunnel, meanwhile, it is crushed and generates
Soil and gravel in outer limited diameter cutterhead 400, interior wear down staged that cutterhead 500 and center cutterhead 600 surround and be crushed in cavity
Bump flow；
Three-level driving is crushed: the middle soil generated and gravel are tunneled and be crushed through firsts and seconds in outer limited diameter cutterhead
400, interior to wear down bump flow in the broken cavity of staged that cutterhead 500 and center cutterhead 600 surround, wear down cutterhead in rotation
500 drive main crushing cutter 501 to be crushed again to what gravel and soil synchronized, meanwhile, gravel and soil are in an impact through auxiliary
Crushing cutter 502 and broken notch 503 are collided and are crushed again work；
In cutterhead tunneling process, it is crushed the gravel and soil completed, it, can be through in staged is crushed in cavity and moves
The screening leak hole 700 inside worn down in cutterhead 500 and center cutterhead 600 exports respectively, then through outer limited diameter cutterhead 400, interior wear down
The staged export cavity that cutterhead 500 and 600 dorsal surface of center cutterhead surround is exported to gravel and soil storage cavity, then
Carry out subsequent transportation work.
