In sharp triangle drill.
Further, the height of the positioning drill, level-one drill, two level drill and three-level drill is gradually reduced.
Further, it is welded with pointed positioning protrusion at the top of the mounting post of the two level drill.
Further, the drill pedestal has double-round apopore by center to edge.
Further, the drill base bottom offers the assembling for being welded and fixed with the electromagnetic wave drilling well knife bar
Hole.
Further, the material of the positioning drill, level-one drill, two level drill and three-level drill is top layer chemical vapor
Deposit the hard alloy of 5-7 μm of ultrahard titanium carbide.
A kind of improvement high intensity radio magnetic wave drilling bit of the utility model, compared with prior art with following excellent
Point：
The improvement high intensity radio magnetic wave drilling bit is by setting the columnar positioning drill to make whole drill bit work
There is good stationkeeping ability, so as to drive other drills to carry out deep drilling to the point during work.The level-one drill upper end is
Column drill, so the level-one drill can also play positioning function, and then drives two level drill deep drilling.And positioned at described one
The auxiliary drill of level drill lower part then can further crushing hard rock, this is designed as the two level drill crushing and cuts
Cut rock to get ready work, so that the workload of the two level drill reduces, when rock is after the cutting of two level drill
Directly dish out from the side of the three-level drill, the main function of the three-level drill makes to throw ground and right from center to foreign aid
Rock stratum carries out horizontal broken work.The design makes drill bit can not only the relatively low ground of cutting hardness, additionally it is possible to broken high rigidity
Rock stratum, thus the drill bit possesses the characteristics of applicability is stronger.Each drill cooperates so as to significantly be carried with reaching in the drill bit
Rise the purpose of drill bit drilling efficiency.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the top view of the utility model.
In figure：1st, drill is positioned, 2, level-one drill, 3, two level drill, 4, three-level drill, 5, apopore, 6, drill pedestal.
Embodiment
In order to be better understood from the utility model, with reference to specific embodiments and the drawings to the utility model into advance one
The description of step.
As shown in Figs. 1-2, a kind of improvement high intensity radio magnetic wave drilling bit, including for electromagnetic wave drilling well knife bar
The drill pedestal 6 being fixedly connected, 6 top end surface of drill pedestal are welded with drill mounting disc.Open 6 bottom of drill pedestal
Equipped with the pilot hole for being welded and fixed with the electromagnetic wave drilling well knife bar.The drill mounting disc carries for being welded and fixed for drill
Facility has been supplied, and connection of the design of the pilot hole then between the drill pedestal 6 and electromagnetic wave drilling well knife bar provides
It is convenient.
The center of the drill mounting disc is welded with column positioning drill 1, the institute centered on the positioning drill 1
Stating equidistant uniform welding in drill mounting disc has a loop pillar shape level-one drill 2, the drill peace of 2 periphery of level-one drill
Equidistant uniform welding has a circle two level drill 3 in sabot, in the drill mounting disc arround the two level drill 3 equidistantly
Uniform welding has a circle three-level drill 4.
The top of the positioning drill 1 and the level-one drill 2 is for ease of piercing the sharp tip structure of rock interior.Institute
State the auxiliary sheet drill that level-one drill 2 includes being located at the column drill at top and being welded and fixed with the column drill bottom.
The two level drill 3 includes the enhancing column being welded and fixed with the drill pedestal 6, the enhancing top end welded and installed column, institute
State the multiple arcs drill that equidistantly distributed is welded with arround mounting post circumference side.The three-level 4 is located at drill installation
The outer ring edge of disk, the transverse direction drill 4 is in sharp triangle drill.
By setting the columnar positioning drill 1 to make that there is good stationkeeping ability during whole bit operation, from
And other drills are driven to carry out deep drilling to the point.2 upper end of level-one drill is column drill, so the level-one drill 2
Positioning function can be played, and then drives 3 deep drilling of two level drill.And positioned at the auxiliary drill of 2 lower part of level-one drill
Then can further crushing hard rock, this is designed as the two level drill 3 and crushes rock cutting getting ready work, from
And reduce the workload of the two level drill 3.
When rock by two level drill 3 cutting after directly dish out from the side of the three-level drill 4, the three-level drill 4
Main function make from center to foreign aid throw ground and to rock stratum carry out horizontal broken work.As it can be seen that the design makes drill bit not
Only being capable of the relatively low ground of cutting hardness, additionally it is possible to broken high rigidity rock stratum, thus the drill bit possesses the characteristics of applicability is stronger.
In order to lift the deep drilling efficiency of the two level drill 3, to prevent situation about being had skidded in drilling process, so
Pointed positioning protrusion is welded with the top of the mounting post of the two level drill 3.In order to further improve the positioning drill 1, level-one
The synergistic effect of drill 2, two level drill 3 and three-level drill 4, so positioning drill 1, level-one drill 2, two level drill 3 by described
It is gradually reduced with the height of three-level drill 4, which can make each drill in the drill bit cooperate so as to reach notable
Lift the purpose of drill bit drilling efficiency.
Substantial amounts of heat can be produced during rock stratum scleroid due to the drill bit deep drilling, so in the drill pedestal 6 in
The heart to edge has double-round apopore 5.The design can accelerate the cooling velocity of the drill bit, drill bit is continued work
Make.The statement that drill bit present position carries out in Fig. 1 is subject in top and bottom described in the present embodiment.
In order to further improve the hardness and wearability of the drill bit on the basis of structure is optimized, so by the spitting drill
Knife 1, level-one drill 2, the material of two level drill 3 and three-level drill 4 are hard for 5-7 μm of ultrahard titanium carbide of top layer chemical vapor deposition
Matter alloy.The hard alloy be using tungsten-carbide powder as matrix, with cobalt powder make binding agent it is pressurized, sintering form, the hard close
Gold contains tungsten carbide 94%, containing cobalt 6%.In order to improve the service life of the drill bit, it is possible to by the drill mounting disc and institute
Drill pedestal 6 is stated to prepare using the hard alloy.
The embodiment of the utility model is described in detail above, but the content is only the preferable of the utility model
Embodiment, it is impossible to be construed as limiting the scope of the utility model.All impartial changes made according to the scope of the utility model
Change and improvement etc., should all still belong within this patent covering scope.
