It cannot be understood as indicating or implying relative importance.Meanwhile in the description of the present invention, unless otherwise specific regulation and
It limiting, term " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or
It is integrally connected；It can be mechanical connection, be also possible to be electrically connected；It can be directly connected, intermediary can also be passed through
It is indirectly connected.For the ordinary skill in the art, above-mentioned term can be understood in the present invention with concrete condition
Concrete meaning.
The utility model provides a kind of technical solution: rock tunnel(ling) machine double-edged hobbing cutter, including 1 He of cutterhead referring to FIG. 1-2,
Cutter shaft 2, it is characterised in that: interference fit connection is realized between the cutter shaft 2 and the center of cutterhead 1；The table of the cutterhead 1
Face offers multiple installation card slots 4, and the installation card slot 4 is embedded and is equipped with cutter head assembly 5, the cutter head inside it
Component 5 includes tool apron 501, blade 502, helical edges 503 and moves back soil box 504, is realized between the tool apron 501 and installation card slot 4
Clearance fit, the blade 502 are welded in one with tool apron 501, and the helical edges 503 form one, institute by the cutting of blade 502
Stating and moving back soil box 504 is in that insertion is set between helical edges 503 and blade 502；It is equipped between the cutter shaft 2 and installation card slot 4 close
Storehouse 3 is sealed, and 3 hollow out of the gas-tight silo is set in cutterhead 1, the end of the cutter shaft 2 is connected with cutter shaft mounting head 201.
More specifically, the side of the cutterhead 1 is equipped with the spacing collar 6 of annular, and the spacing collar 6 approaches and is embedded in peace
Be loaded the setting of 4 bottom of slot, on the one hand increases the counterweight of cutterhead 1 by the spacing collar 6 of setting, on the other hand mainly prevents tool apron
