It is in 30-60 ° of angle to contrary with drill bit 301, and with the pole face of drilling rod 302, four second row stomatas 308 are not located at same
In level cross-sectionn, preventing internal stress from generating reduces by 302 intensity of drilling rod.The effect of second row stomata 308 is: when beating deep hole
(being greater than bit depth), caisson input high pressure pneumatics wind by gas-guide tube, and pneumatics wind passes through second row stomata 308 to outside
Exhaust is conducive to the substance that will be cut using high pressure pneumatics wind and is discharged along drilling；After present invention punching, it is not required to
Drill bit 301 is taken out, continues logical high pressure pneumatics wind using gas transmission air flue 307 and cleans out drilling, then pass through gas transmission air flue
307 low temperature liquid nitrogen injection hole, liquid nitrogen are discharged by second row stomata 308 from drilling rod 302, can reduce rapidly four walls of drilling
Temperature can quickly carry out next step program, the i.e. program of loading medicinal powder progress explosion, its operating process is made to become simpler
It is single, it is faster.Further, the preferred 45° angle of face angle of second row stomata 308 and drilling rod 302, in this way setting are more conducive to
Auxiliary discharge cutting object and more conducively reduction borehole temperature.
302 outside of drilling rod is also arranged with dust collector 310 in the present invention, and dust collector 310 is folding umbellate form,
Its middle part is hollow circular.Dust collector 310 is mobilizable to be sheathed on drill bit 301 or drilling rod 302, and no matter drill the depth,
Dust collector 310 can be moved into the outside of drilling, can be timely when the substance cut is discharged along drilling rod 302
It is collected, prevents from causing environmental pollution, prevent flue dust from entering human body, it is unhealthful, prevent flue dust from entering equipment, influencing equipment makes
With.Dust collecting connects the dust collector 310 by dust pipe in the present invention.
Heretofore described gas storage dust suction power supply device be fixed on the bracket 106 and with the power and master control device
It is electrically connected, entire fast cooling perforating device 300 is controlled convenient for power and master control device.
It can also include multiple brills in fast cooling perforating device 300 to advanced optimize technical solution of the present invention
Bar 302, multiple drilling rods 302 can also be detachably connected by screw thread, can satisfy the punching demand of different depth in this way, when necessary
By increasing by 302 quantity of drilling rod, increase drilling depth.Further, between drill bit 301 and drilling rod 302, multiple drilling rods 302
Junction be provided with the fixed cotter way of rectangle, fixed pin 309 is placed in the fixed cotter way of rectangle, when drill bit 301 and drilling rod
After 302 connections, it is put into relative position of the fixed pin 309 to fixed drill bit 301 and drilling rod 302, prevents from deflecting when rotation,
Increase its effect for resisting stress, ensure that the steady operation of drill bit 301.
Further, can have length difference, including long drill pipe and short drill pipe between multiple drilling rods 302, long drill pipe with
Structure in upper embodiment is identical, and short drill pipe is also hollow structure, but second row stomata is not provided on the body of rod.When explosion is punched
When needing to carry out shallow blasting, i.e., when its depth is with 301 same length of drill bit, it can be used and be not provided with second row stomata
308 short drill pipe；Or the drilling rod 302 connecting with gas storage dust suction power supply device does not have to setting when not directly entering bore inner
Second row stomata 308, so short drill pipe can also be used.The use of short drill pipe prevents second row stomata 308 is naked to be exposed on the external
The waste that pneumatics wind or cooling material are caused in present invention work, thereby reduces the energy consumption of gas storage dust suction power supply device, guarantees
Equipment being capable of efficient operation.
