Compared with prior art, it utility model works principle and has the beneficial effect that
1, in the utility model, dry to drill including drilling rod, drill bit, drilling rod is hollow, and several strip-shaped holes are provided on drilling rod, bores
If being provided with drilled dry tooth on head, bores tooth and be circumferentially arranged along drill rod end, and have gap between two neighboring brill tooth, existing dry
Increase gauge on the basis of drilling and protect tooth, gauge shield tooth is positioned close to bore on the drilling rod side wall at tooth, and circumferential along drilling rod side wall
Setting.Drill bit is pierced by high speed rotation in hard object, such as concrete, masonry, spaced brill tooth and drilling rod
On strip-shaped hole can increase the grey rate of discharge, accelerate drill bit heat dissipation performance, the clast drilled out does not easily cause bit freezing.Boring tooth side
Circumferential setting gauge protects tooth, and the diameter finally to drill is identical as the gauge shield drill pipe diameter of transverse tooth thickness degree is increased, and is advantageous in that,
On the one hand as gauge shield tooth pierces in drilling, increase boring aperture, the hole of discharge clast can be increased, preferably avoid card
The case where boring to enter caused by brill, on the other hand, gauge shield tooth, which is arranged, can be avoided drilling rod and drilling generation friction, make
Pierce it is more laborsaving, in addition it is possible to play the role of guiding, gauge shield tooth can make to pierce it is more firm, if boring tooth drilling
Some deflections, to gauge shield tooth and drilling plane contact when can discover drilling whether deflection, it is easy to adjustment in time, improve brill
The whole service performance of head.
2, in the utility model, gauge protects tooth and bores tooth there are certain distance, and desirable 1cm-2cm can be pierced initially
When avoid interfering to bore tooth drilling, gauge shield tooth can initially enter drilling after tooth to be drilled enters one section of small distance, can be fine
Reduction bit freezing situation occur, can also adjust the drilling of deflection in time.
3, in the utility model, gauge shield transverse tooth thickness spends the small effect for not having and increasing clast discharge gap, and thickness is excessive
Cause to make the dry consumptive material increase drilled, and is easy to cause rotation unstable in boring procedure, and it is too many to be extended drilling, shadow
Actual use is rung, therefore selects gauge shield tooth with a thickness of 0.4cm-0.6cm according to test of many times, it is real to be able to use least material
Existing predetermined action.There are three gauge shield tooth is total, there is gap between adjacent gauge shield tooth, for clast to be discharged.
4, in the utility model, disassembly is provided with the deep regulating device of brill on drilling rod, since drilling rod rotation speed is fast, and drilling rod
On without scale, unfamiliar new person is easy to hold inaccurate drilling depth, therefore can install the deep regulating device of brill and bore to control
Hole depth, boring deep regulating device includes identical two buckles of size, and buckle both ends are provided with bolt hole, and bolt is inserted into two buckles
In opposite bolt hole and nut is tightened, is fixed on buckle on drilling rod, buckle lower section is connected with divider, and two dividers connect
Being in the bowl-shape of back-off.On the one hand brill can be controlled deeply to the distance for boring tooth by adjusting divider end, on the other hand can also
It enough stops to collapse to splash from the clast of drilling discharge and do harm to huamn body.
5, it in the utility model, bores and is provided with strip groove on tooth medial lateral, the setting of strip groove is capable of increasing broken
It considers the path clearance of discharge to be worth doing, reduces bit freezing, and can increase when most rough drill tooth pierces and the friction on drilled object surface, subtract
It is few to skid.
6, in the utility model, the strip-shaped hole on drilling rod is parallel to drill rod axis, and strip-shaped hole can be accelerated high-speed rotating
The heat dissipation of drill bit drilling rod, and have the function of that clast is discharged, the strip-shaped hole technical requirements for being parallel to drill rod axis are lower, convenient
Production.
7, in the utility model, strip-shaped hole is tilted a certain angle relative to drill rod axis, and inclined direction is along rotation side
To making clast be easier to be discharged, angle setting is excessive to be not easy punch forming, therefore it is 10 ° -20 ° that its angle, which is arranged,.
8, in the utility model, brill tooth is diamond material, has very high hardness, can bore open hard objects, gauge
Shield tooth undertakes the power of grinding drill hole inner wall, therefore is also required to hardness with higher, is made using diamantiferous metal material.
