Abstract
The present invention relates to a kind of Novel cutting tooth, it is hollow by the cutting tooth I of the hard alloy cone head with polycrystalline diamond composite coating and head, upper outer surface is taper, helical structure is welded on the face of upper surface, middle part is cylinder, and shank is the pedestal II of thin cylinder composition by being welded.After such scheme, the contact area of welding is improved, and greatly improves the impact resistance and wearability of diamond composite teeth, the service life of pick is greatly extended；And because cutting tooth I and pedestal II improve the torque resistant ability of pick using three prismatic male-female engagement modes；And helical structure can reduce the size of coal cinder in the pick course of work by cutting coal petrography, so as to accomplish the micronization processes to coal petrography.
Description
Technical field
It is specifically related to a kind of new section the invention belongs to tunnelling machine, coal-winning machine and shield machine, rotary drilling rig field
Tooth.
Background technology
In the prior art, development machine, fully mechanized mining machine and shield machine, rotary drilling rig are widely used in various colliery tunnel piercing works
In journey construction.Cutterhead is development machine, fully mechanized mining machine and shield machine, the critical piece of rotary drilling rig, and pick passes through cutting pick handle and tooth
Seated connection is touched and is fixed on corresponding toothholder, and pick is generally referred to as hard alloy pick, mostly circular cone using hard alloy crown
Profile, and directly fix.In practical work process, cutterhead, by pick cutting rock, is main in the way of impacting
Stressed member, and the coal cinder produced in practice or other material blocks grain are larger, and follow-up processing also needs to multiple reduction
Granularity.
In the course of work in pick, cutterhead to the impact of coal petrography to realize brokenly coal function, it is higher running into hardness
Rock stratum when, by larger shock loading and friction, hard alloy pick abrasion thereon is very fast, has had a strong impact on work effect
Rate.Therefore a kind of impact resistance abrasion and can reduce output object granularity pick be in process of production in the urgent need to.
The content of the invention
In order to solve the above-mentioned technical problem, the invention provides the Novel cutting tooth that a kind of impact resistance is strong, wearability is high.
The scheme that present invention solution above-mentioned technical problem is taken herein is as follows:Pick is made up of cutting tooth and pedestal.Cut
Tooth is cut to be made up of tapered head, and joint portion；Cone head, and joint portion material are hard alloy；While cone head
Surface scribbles one layer of diamond composite so that the wear resistance of cutting tooth is improved.Base material is hard alloy.
Further make the pick of cutting movement in rotation substantially can be acted on by moment of torsion.Base material closes for hard
Gold;The head of pedestal is hollow, and hollow area is prismatic, and joint portion is also prismatic;This ensure that cutting tooth and pedestal
While there are enough contact surfaces to prevent it by conquassation, the torque resistant ability of pick is improved.
The top of further pedestal is taper;Ensure that pick is crushed using stress concentration effect to coal petrography, justify relatively
For cylindricality, the impulsive force that pick is subject to is smaller, but bigger to coal petrography pressure, so extends the life-span of pick.
Helical structure is welded on the top of the taper of pedestal II.During pick rotates, helical structure is bright
Show to coal petrography pivotal cutting movement, can so reduce the size of coal cinder, be that follow-up coal processing procedure reduces the heavy burdens.
The middle part of further pedestal is cylinder, to the conical upper of pick, with cutting pick handle, forms pressure buffer band, this
Improve the intensity of pick.
Other features and advantages of the present invention will be illustrated in the following description, or by the implementation present invention
Solution.The purpose of the present invention and other advantages can be by being referred in particular in the specification, claims and accompanying drawing write
Go out.
Brief description of the drawings

Embodiment
With reference to the accompanying drawings and examples, the embodiment to the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
Pick is made up of cutting tooth I and pedestal II, is that cutting tooth is placed on pedestal during both welding, by the knot of pick
Conjunction portion is placed in the hollow area of seat head 3 so that the bottom on cutting tooth head is contacted with Chuck top, due to Chuck top
II is the circle of a bottom than cutting tooth head 1 greatly, can be very good accommodate welding material, and welding material can melt with
It is pressed in afterwards while with being attached to Chuck top on the conical surface of cutting tooth head 1, so not only make use of the anti-of welding material
Drawing property, also utilizes the resistance to torsion of welding material.So that cutting tooth and pedestal can be very good to fix.
Cutting tooth I is made up of tapered head 1, and joint portion 2;Cone head 1, and joint portion 2 is by hard alloy；Together
When the surface hard alloy of cone head 1 above be put into diamond powder and binding agent, HTHP sintering is into causing cutting tooth
Wear resistance improve.
Make the pick of cutting movement in rotation substantially can be acted on by moment of torsion.The material of pedestal II is hard alloy;Base
The head 3 of seat II is hollow, and for prismatic, it is milled out hollow area using milling cutter;Joint portion 2 is also prismatic, is also in casting
On the basis of milled out with milling cutter;This ensure that cutting tooth I has enough contact surfaces with pedestal II, so as to prevent it by conquassation
Meanwhile, improve the torque resistant ability of pick.
Helical structure 4 is formed by hard alloy casting;Helical structure 4 uses hydrogen arc welding technology, by tungsten carbide filler rod built-up welding
On helical structure 4 and the contact area of the conical upper 5 of pedestal II.Matrix II is preheated before welding, welded
Insulation is used to matrix II into rear.Strengthen the abrasion resistant effect in matrix area easy to wear with this.Rotated in pick
During, helical structure 4 can so reduce the size of coal cinder, so as to accomplish to coal substantially to coal petrography pivotal cutting movement
The micronization processes of rock.
The top 5 of pedestal II, the cutting pick handle 7 of middle part 6 is integral, is to be formed by hard alloy casting after cylindrical shape, to circle
Post Vehicle Processing goes out top 5, the cutting pick handle 7 of middle part 6;The middle part of pedestal II 6 is cylinder, to the conical upper 5 and cutting pick handle 7 of pick it
Between, pressure buffer band is formed, this improves the intensity of pick.
Improving the cutting pick handle 7 of pedestal II at low temperature can be placed on pick in liquid nitrogen after cooling using principle of expanding with heat and contracting with cold
It is fitted close with the toothholder of normal temperature.Pick will be fitted close with toothholder after recovery temperature is normal.
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., should be included in
Within protection scope of the present invention.Those skilled in the art are it is to be appreciated that specific descriptions above are intended merely to explain the present invention
Purpose, be not intended to limit the present invention.Protection scope of the present invention is limited by claim and its equivalent.
