Abstract
The utility model discloses a kind of using diamond single crystal as inserted hard rock hob, diamond single crystal is installed on the outer surface of knife shell, the diamond single crystals more than two circles or two circles is at least installed with along the peripheral surface of the knife shell, rock slag chute is offered on the knife shell between diamond single crystal described in two adjacent rings.The utility model hard rock hob is by the use of diamond single crystal as inserted, and hardness is big and wearability is good, is crept into suitable for the broken rock of extremely solid rock.
Description
Technical field
The utility model is related to wellbore construction devices.More particularly, to one kind using synthetic diamond single crystal as inserted
Hard rock hob.
Background technology
Hard rock hob of the prior art is inserted using hard alloy, and the hardness of hard alloy is smaller and wearability is poor,
For extremely hard rock, it is unfavorable in cutter tooth plutone.
It is 2016YFC0600802, the entitled " metallic ore of problem in project number based on defect in the prior art
Deep shaft high efficient driving with into well key technology and equipment " research topic in, applicant is specifically for the difference of Hob for cutting rock
Species is inserted to be studied in detail, and solves problems of the prior art.
Utility model content
One of the utility model is designed to provide the hard rock hob that a kind of hardness is big and wearability is good, suitable for extremely
The broken rock drilling of solid rock.
In order to achieve the above objectives, the utility model uses following technical proposals：
It is a kind of using diamond single crystal as inserted hard rock hob, diamond list is installed on the outer surface of knife shell
It is brilliant.
It is above-mentioned using diamond single crystal as inserted hard rock hob, be at least installed with along the peripheral surface of the knife shell
The diamond single crystals more than two circles or two circles.
It is above-mentioned using diamond single crystal as inserted hard rock hob, the knife between diamond single crystal described in two adjacent rings
Rock slag chute is offered on shell.
It is above-mentioned using diamond single crystal as inserted hard rock hob, the rock slag chute along the knife columella to cross section take turns
Exterior feature is parabola.
It is above-mentioned using diamond single crystal as inserted hard rock hob, the grain size of the diamond single crystal is 15-20mm, described
Parabolical burnt standard is 13-18mm away from the groove depth for 2.4-2.8mm, the rock slag chute.
The beneficial effects of the utility model are as follows：
1st, the broken rock cutter tooth inlayed on knife shell uses diamond single crystal tooth.
2nd, it is inserted compared with original hard alloy suitable for extremely solid rock, since hardness improves, it is more advantageous to cutter tooth
In the rock mass of intrusion.
3rd, diamond hardness is high, the hard-metal insert that wearability compares before, and the service life improves 3 times.
4th, since the inserted rock breaking efficiency of diamond single crystal is good, rock solid impurity particle is larger, and knife shell rock slag chute is improved, is adopted
With circular arc deep groove, be conducive to the exclusion of rock slag, prevent abrasion knife shell, the knife shell service life can be extended more than 50%.
5th, a variety of diamond single crystal tooth forms can be inlayed, it is full including hemi-spherical ended shape insert, conical tooth, chisel teeth and parabola shaped tooth
The demand of foot difference efficiency of breaking rock.
It 6th, can be to compared with soft rock, using interval cloth tooth mode, a part uses diamond for the rock of varying strength
Monocrystalline, a part are inserted using ordinary rigid alloy.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 the utility model is using diamond single crystal as the structure diagram of inserted hard rock hob.
Wherein：1- knife shells；2- diamond single crystals；3- rock slag chutes；4- cutter shafts.
Specific embodiment
In order to illustrate more clearly of the utility model, the utility model is done into one with reference to preferred embodiments and drawings
The explanation of step.Similar component is indicated with identical reference numeral in attached drawing.It will be appreciated by those skilled in the art that below
Specifically described content is illustrative and be not restrictive, and should not limit the scope of protection of the utility model with this.
As shown in Figure 1, the present embodiment is a kind of using diamond single crystal as inserted hard rock hob, in the appearance of knife shell 1
Diamond single crystal 2 is installed on face.And along the peripheral surface of the knife shell 1 be at least installed with two circles or two circle with
On the diamond single crystal 2, offer rock slag chute 3 on the knife shell 1 between diamond single crystal 2 described in two adjacent rings.Institute
It is parabola that rock slag chute 3, which is stated, along the axial cross-sectional profiles of the knife shell 1, and the grain size of the diamond single crystal 2 is 17mm, described
Parabolical burnt standard is 15mm away from the groove depth for 2.58mm, the rock slag chute 3；The knife shell service life can be extended more than 70%.
Obviously, above-described embodiment of the utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to the embodiment of the utility model, for those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways, all embodiments can not be exhaustive here,
It is every to belong to obvious changes or variations that the technical solution of the utility model is extended out still in the utility model
The row of protection domain.
