The purpose of the utility model realizes through following technical scheme:
A kind of hard rock cutter head of shield machine structure; Comprise that cutterhead, said cutterhead are provided with the tool rest that is welded with drum type brake in cutterhead support, the said cutterhead support, be placed with the column type hobboing cutter in the said tool rest, said tool rest inside is cavity; Said tool rest inwall up and down has the fixedly used chamfered groove of hobboing cutter; The shape of said chamfered groove and rectangle carrier block coupling, three faces of said rectangle carrier block can and have the column type hobboing cutter end cap that carries the side with two faces of chamfered groove and contact fully, and the location cooperatively interacts; The top of said rectangle carrier block is placed with latch segment, said latch segment and rectangle carrier block Bolt Connection.
Further, said tool rest is single chamber tool rest, two-chamber tool rest and four chamber tool rests; The inwall up and down of said single chamber tool rest has four chamfered grooves, and the inwall up and down of said two-chamber tool rest has six chamfered grooves, and said four chamber tool rests inwall up and down have ten chamfered grooves.
Further, be provided with the boss of restriction rectangle carrier block shifted laterally on the said hobboing cutter end cap.
Further, said rectangle carrier block and latch segment are provided with direction protrusion and groove.
The beneficial effect of the utility model is: owing to inwall about the tool rest that is employed in its drum type brake is offered chamfered groove, can adopt back of the body formula tool changing mode (at the back of shield machine dish replacing hobboing cutter) when making shield machine installation or construction replacing hobboing cutter; Owing to adopt on the rectangle carrier block latch segment is installed, its two bolton connects, and can make hobboing cutter fixing more firm, easy for installation, and this mounting means is not only firm, and has avoided a large amount of cost that welding brought height, the problem that precision is inaccurate.
