Abstract
The content of present invention mainly provides a kind of pressure wind cooling deslagging compact bit, its primary structure is by coronal structure main body, press the structure compositions such as wind spray orifice device and composite sheet, coronal structure body top is that more bodies divide wing combined shaped, bizet wing location arrangements have composite sheet, composite sheet lower end is equipped with the outlet of pressure wind, the outlet of pressure wind carries out wind cooling temperature lowering by high-pressure blast to composite sheet prevents the burning of bits caused by deficiency in draught and wind speed are inadequate, phenomena such as abrasion, drill bit generated bit freezing phenomenon when creeping into tomography can be effectively solved by the way that high pressure is air-cooled, and be water cooling drilling 4-5 times.
Description
Technical field
The invention mainly relates to a kind of pressure wind cooling deslagging compact bits, are mainly used for mining, engineering the drilling, road
The numerous areas such as the trepanning of base engineering and geological prospecting detection drilling use.
Background technology
PDC diamond compact bit developing histories are long, can trace back to last century, presented by constantly reforming development
Go out the drill bit form of diversified forms to ensure the continuous promotion of drilling efficiency, by water filling or note wind to reach in boring procedure
To the purpose of composite sheet cooling, prevent from causing compound pad wear to fall off due to the temperature caused by high speed rotary grinding is excessively high.Water filling
During drilling is implemented, since water size variation and the soft degree of formation rock are different, usually expansion can be developed because of water rock is met
Plug-hole is caused, and water filling drilling often causes bit freezing when carrying out negative angle and vertical drilling because anti-slag effect is poor, in
Way stops boring causes drilling rod locking because landwaste meets water-setting admittedly, therefore water filling drilling is not suitable for compact bit and bores in many cases
Hole uses.Wind pressure is transferred to by drill pipe bore at compact bit when common wind pressure drilling, when transmission due to drilling rod sealing and
Fed distance is longer to cause air quantity loss that effective cooling-down effect is not achieved, and since ventilation aperture is larger, air quantity dispersion is uneven,
It is unable to reach good deslagging effect.
Invention content
The purpose of the present invention is a kind of pressure wind cooling deslagging compact bits, and specific manifestation mode is that drill bit is more
Body divides wing combined shaped, bizet wing location arrangements to have composite sheet, composite sheet lower end to be equipped with the outlet of pressure wind, and the outlet of pressure wind is according to multiple
It is in inclination angle opposite direction composite sheet surface to close piece arrangement, and pressure wind exit lower end is connected equipped with vent passages with main air duct, and lower part, which is equipped with, bores
Handle is machined with the attachment device for connection in drillstock.
A kind of pressure wind cooling deslagging compact bit in summary, it is characterised in that the pressure wind that composite sheet lower end is equipped with goes out
Mouthful, air outlet aperture is not more than 2mm, and the outlet of pressure wind and composite sheet angle are between 110 ° ~ 115 °, by high-pressure blast in 2mm
Rapidly jet stream wind is formed in spray orifice, then according to angle arrangement blow-through composite sheet drilling basil position, to reach rapid cooling
Purpose.
A kind of pressure wind cooling deslagging compact bit in summary, it is characterised in that the outlet of pressure wind is apart from composite sheet 10-
15mm。
A kind of pressure wind cooling deslagging compact bit in summary, it is characterised in that air outlet is in more bodies with bizet wing
Distribution of shapes, air outlet front end are provided with antifriction alloy.
It is a kind of to press wind cooling deslagging compact bit that effectively solve high temperature burning piece phenomenon caused in drilling process,
And crept by high wind pressure and increase deslagging speed, effectively achieve the purpose that energy-saving.

Specific implementation mode
It is described as follows with reference to the figure and specific practicality covered in attached drawing：
According to as shown in the figure, the coronal structure main body 1 of pressure wind cooling deslagging compact bit is that more bodies divide wing combined shaped, coronal
1 wing location arrangements of main structure body have composite sheet 5,5 lower end of composite sheet to be equipped with pressure wind outlet 4, and pressure wind exports 4 lower ends and is provided with side
Air duct 3, and connect with main air duct 2 by crosswind road 3,1 bottom of coronal structure main body is equipped with the guarantee of attachment device 7 can be with other
The connection of tool interworking uses, and the coronal concave surface in top is equipped with newel 8 and upper air outlet 6, and 8 top of newel is equipped with composite sheet 5,
Shield diameter alloy 9 is equipped with around 1 top of coronal structure main body is coronal,
Press wind export 4 apertures be not more than 2mm, pressure wind outlet with composite sheet angle between 110 ° ~ 115 °, pressure wind outlet 4 and again
Close 5 distance 10-15mm of piece.
