Using fishtail, frequently with two tool arms, in one line, with cutter head center line as axis of symmetry, form axially symmetric structure, and all adopt
Fixed with the mode of welding, non-dismountable, when needing more allowing blade replacement once being damaged, need whole center cutter is carried out more
Change, high cost.
The utility model patent of Publication No. CN203271749U discloses a kind of miniature shield machine on November 6th, 2013
Cutterhead, including circular knife rest, is located at the center cutter in the knife rest center of circle, along the setting of knife rest radial direction cutterhead spoke, be located at cutterhead
Multiple cutting knifes on spoke, along multiple all edge doctors of knife rest periphery setting, multiple along the setting of knife rest periphery are fixed on knife rest
On periphery dual-pilot cutter, along cutterhead spoke length direction setting multiple dual-pilot cutters being fixed on knife rest, described center cutter, week
Edge doctor and cutting knife are all connected with knife rest using round end hexagon socket head cap screw attachment structure.
Although this utility model achieves being detachably connected of center cutter, the center that the mode of being bolted connects
Knife easily loosens in use for some time, there is certain potential safety hazard.
Content of the invention
The defect easily loosening for the center cutter being detachably connected present in prior art, the utility model discloses
A kind of shield machine cutter, can effectively solve the problem that, using this utility model, the defect that center cutter easily slides.
