Background technology
With the continuous development in China city, subway plays an important role in terms of urban traffic pressure is alleviated, mesh
Preceding the application of shield machine is more and more extensive in subway work, and hobboing cutter is the cutter for being used to tunnel on shield machine, for rock
Crushed and cut.Wherein hobboing cutter is made up of hobboing cutter body, installs alloy by cutter ring in the middle part of hobboing cutter body, cutter ring is by a fixation
Ring is installed on hobboing cutter body；Either import knife or domestic hobboing cutter is all made up of rigid material in the prior art, uses
Cheng Zhong, cutter ring wearability is poor, when running into the complex geological conditions such as hard rock, silt, the skills such as cutter ring stalling eccentric wear easily occurs
Art problem, causes cutter ring to come off, and then hobboing cutter is integrally scrapped, and greatly shortens service life, and the economy for increasing enterprise is born
Load.
Publication No. CN201696053U patent of invention disclosed a kind of shield machine hob ring on January 5th, 2011, bag
Hobboing cutter circle body is included, feature is that annular groove is provided with the excircle of circle body, soldering Circular Hard Alloy in groove.By hard alloy
Rolling operation is completed, the excessive wear of circle body is avoided, enhances the anti-wear performance of circle body, effectively increase Hob ring uses the longevity
Life, reduce production cost.
Although the invention realizes the purpose for improving Hob ring service life, but a defect, i.e. hard alloy be present
It is installed on by way of welding in groove, can not realizes after hard alloy abrasion and fast, easily change, and then cause to roll
Cutter ring is integrally scrapped, and increases the production cost of enterprise.
The content of the invention
It is short for hobboing cutter service life present in prior art, the defects of difficult is changed, the invention discloses a kind of shield
Structure machine hobboing cutter, the service life of hobboing cutter can be effectively improved using the present invention, while changed conveniently, successfully reduce the life of enterprise
Produce cost.
The present invention is achieved through the following technical solutions above-mentioned purpose：
A kind of shield machine roller cutter, including hobboing cutter circle body, it is characterised in that：The Hob ring is provided circumferentially about in vitro radially installed
Hole, end face of the radially installed hole also with hobboing cutter circle body are communicated, and the hard alloy blocks are arranged in radially installed hole, hard alloy
The profile of block is in I-shaped or swallow-tail form；It is connected between the hard alloy blocks and hobboing cutter circle body by connecting screw.
The tail end of the connecting screw is provided with regular hexagon blind hole.
The tip protrusion of the hard alloy blocks is concordant in the external circumference of Hob ring or circumference external with Hob ring holding.
One layer of wearing layer is welded with the external circumference of Hob ring.
The hard alloy blocks and the connecting screw at least two set on hobboing cutter circle body.
Compared with prior art, the invention has the advantages that：
1st, a kind of shield machine roller cutter of the present invention, including hobboing cutter circle body, it is characterised in that：On the external circumference of Hob ring
Radially installed hole is provided with, end face of the radially installed hole also with hobboing cutter circle body communicates, and the hard alloy blocks, which are arranged at, radially pacifies
Fill in hole, the profile of hard alloy blocks is in I-shaped or swallow-tail form；Pass through connection between hard alloy blocks and the hobboing cutter circle body
Screw rod is connected, and the hard alloy blocks of connecting screw connection are easy to dismount, while middle radially installed hole small, that two is big can be right
Hard alloy blocks progress is radially spacing, ensures two section intensity of hard alloy blocks；Symmetrical hard alloy blocks both ends
Used as cutter head, improve the service life of hard alloy blocks, increase economic efficiency.
2nd, the tail end of connecting screw of the present invention is provided with the blind hole of regular hexagon, can be hidden by whole connecting screw
It is hidden in inside hard alloy blocks, avoids connecting screw from being excessively ground by rock-soil layer and influence bonding strength.
3rd, the tip protrusion of hard alloy blocks of the present invention is protected in the external circumference of Hob ring or circumference external with Hob ring
Hold and flush, ensure that hard alloy blocks can fully contact with dirt bed, avoid only Hob ring from cutting ground, improve rolling
The service life of cutter ring.
4th, one layer of wearing layer is welded with tool rest of the present invention, delays the rate of wear of cutter by wearing layer, is improved
Cutter life.
5th, the connecting screw at least two that the present invention is set, ensure that hard alloy blocks can firmly be installed on Hob ring
On body, the security of cutter is improved.
