Summary of the invention
The purpose of this utility model is to provide the shield machine smear metal cutter that a kind of cutter head can be changed.
For achieving the above object, the technical solution adopted in the utility model is: a kind of self and cutter head be removable shield machine cutting cutter all, it comprises the handle of a knife that is connected with the cutterhead of shield machine and the cutter head removably connecting with described handle of a knife, described handle of a knife comprises handle of a knife body and is coated on the Hard Chromium Coating of described handle of a knife body periphery, described cutter head lower end is connected with described handle of a knife, its upper surface is by the umbilicate arcwall face of two side direction, and the axis of this arcwall face and handle of a knife is perpendicular or arcwall face with respect to being obliquely installed with handle of a knife, when bite is installed on the transition face of cutterhead end face and side, arcwall face is with respect to being obliquely installed with handle of a knife and its sharping degree and transition face angle of inclination match.
Optimize, described cutter head welds with described handle of a knife phase joggle and joint.
Further, described cutter head and described handle of a knife opening joggle, and the tenon width on handle of a knife is 69～71mm, tenon ditch size and tenon on described cutter head are of a size of interference fit.
Optimize, the sidewall of cutter head that is positioned at the tenon both sides of handle of a knife is provided with wearing layer, and the thickness of described wearing layer is less than 1.5mm, and width is 9～11mm.
Further, described cutter head is included in cutter head matrix that described handle of a knife is connected and processes through hardfacing, is arranged at the wear-resisting alloy block on described cutter head matrix, on described cutter head matrix, offer the draw-in groove that a plurality of axial directions along arcwall face extend, described wear-resisting alloy block is arranged in described draw-in groove.
Further, described draw-in groove has three, is respectively and offers the middle part draw-in groove middle with cutter head matrix arcwall face, is positioned at the side bayonet slot on arcwall face and sidewall.
Optimize, on the lower surface of described handle of a knife, offer the removal hole that extends and be convenient to bite replacing along its axis direction.
Because technique scheme is used, the utility model compared with prior art has following advantages: cutter head of the present utility model and handle of a knife removably connect, when cutter head is impaired, only need changes cutter head cannot use time and just can continue to use shield machine, greatly must save cost, and change easyly, improved the efficiency of work.
