Description
Technical field
The utility model is related to cutter accessory field, more particularly to a kind of shield machine cutter.
Background technology
Shield machine is widely used in the construction of the Tunnel Engineering such as railway, highway, municipal administration, water power, the groundwork of shield machine
Principle is that the firm component of a cylinder is excavated along canal axes when pushing ahead to soil.The Cutting tool installation manner of shield machine
On cutter head of shield machine, a variety of cutter work compounds on cutterhead complete excavation, the headwork in tunnel together.
Existing shield machine cutter master alloying body mounting groove is generally straight trough, and its advantage is to install facility, and production cost is low.But
Such a cutter is difficult in adapt to the higher stratum of hardness in actual use, and alloy body rapid wear easily comes off too early.It is common
Shield machine cutter due to design feature and higher frequency of use, each surface abrasion of cutter hub is very fast, and service life is short, improves
Construction cost, while also have impact on efficiency of construction.
Utility model content
A kind of shield machine cutter that the technical problems to be solved in the utility model is to provide, to improve alloy body on cutter head
Steadiness, and its abrasion resistance is lifted, so as to extend the life-span of shield machine cutter.
To reach above-mentioned purpose, a kind of shield machine cutter that the utility model is provided includes：
One handle of a knife, a cutter head, a main hard alloy blocks and two auxiliary hard alloy bars；The cutter head is fixedly arranged on institute
State above handle of a knife, the groove along edge direction is provided with the cutter head blade, the main hard alloy blocks are installed in along cutting edge side
To groove in；It is fixed respectively in groove of the cutter head upper surface provided with two insertion cutter head two sides, two insertion grooves
There is an auxiliary hard alloy bar；The cutter head both sides are provided with multiple hard, wear-resistant blocks.
Preferably, the cutter head is provided with wearing layer on the groove outer periphery surface along edge direction.
Preferably, the cutter head top surface is provided with wearing layer.
Preferably, in described two auxiliary hard alloy bars, the auxiliary hard alloy bar of blade near-end to blade distal end tilt 5 °-
10 °, the auxiliary hard alloy bar of blade distal end tilts 5 ° -10 ° to blade direction.
Preferably, it is T-slot along the groove of edge direction at the cutter head blade.
Preferably, the multiple wear-resistant block is shaped as having chamfering at the top of cylinder, wear-resistant block.
The shield machine cutter master alloying block mounting groove that the utility model is provided is T-slot, makes the company of master alloying body and cutter head
More stable reliability is connect, master alloying body preferably can be fixed on cutter head；Wearing layer at the top of cutting edge peripheral surface and cutter head is protected
The preceding surface of cutter head in mining process is demonstrate,proved and upper surface is adequately protected；The wear-resistant block of cutter head side makes the wear-resisting of cutter head side
Degree gets a promotion, and has chamfering at the top of wear-resistant block so that wear-resistant block is smoother, and the loss situation of wear-resistant block in itself is also changed
It is kind；Auxiliary cemented carbide body at the top of cutter head has certain angle of inclination, makes the mechanical property of cutter head and is improved, improves cutter head
Intensity.Compared with prior art, the shield machine cutter integral firmness that the utility model is provided is higher, and wearability is more preferable, from
And the life-span of cutter can be extended.
