Ring is installed on hobboing cutter body；Either import knife or domestic hobboing cutter is all to be made by rigid material in prior art, using
Cheng Zhong, cutter ring wearability is poor, when running into hard rock with complex geological conditions such as silts, the skills such as cutter ring stall eccentric wear easily
An art difficult problem, causes cutter ring to come off, and then so that hobboing cutter is integrally scrapped, and greatly shortens that service life is short, and the economy increasing enterprise is born
Load.
The utility model patent of Publication No. CN201074516Y discloses a kind of shield machine roller cutter on June 18th, 2008
Circle, including the annular cutter ring being sleeved on hobboing cutter assembly it is characterised in that：It is embedded with hard alloy on the excircle of cutter ring body
Block.This utility model improves the wearability of cutter ring in the case of not affecting cutter ring hardness, has that spoilage is low, service life
Long effect.It is suitable to the driving of hard rock, silt and various complex geological condition, it is to avoid the generation of cutter ring stall eccentric wear phenomenon,
Reduce the production cost of enterprise.
Although this utility model achieves the purpose improving Hob ring service life, there is a defect, i.e. hard
In the alloy groove that alloy is installed on cutter ring by way of welding, can not quickly, conveniently when hard alloy abrasion needs to change
Realization change, or even can not change and lead to Hob ring integrally to be scrapped, increase the production cost of enterprise.
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 hob ring, can effectively solve the problem that, using this utility model, the defect that center cutter easily slides.
This utility model is achieved through the following technical solutions above-mentioned purpose：
