Abstract
The utility model discloses a novel quick streamlined rock drilling bore bit, include the steel body and establish the post tooth at steel body up end steel body lower extreme is opened has the blind hole, is equipped with the air vent of slope on the steel body, the air vent with the blind hole link up, many recesses that meet with the air vent are seted up to steel body up end, arbitrary two adjacent it has an at least auxiliary tank all to communicate between the recess, a plurality of wall grooves have been seted up to steel side wall, the upper end in arbitrary wall groove communicates an auxiliary tank at least. The utility model discloses a rock drilling bore bit can reduce the bore bit in tool joint with the resistance of dike, it is unobstructed to arrange the sediment, has reduced repeated breakage, has effectively improved rock drilling speed, and has improved the life of bore bit.
Description
Technical field
The utility model relates to a kind of drilling tool, especially relates to a kind of novel quick rock drill bit.
Background technology
At present, the widely used rock drill bit in drilling engineering that cuts into a mountain has trousers body, its head is embedded with Internal and external cycle carbide button, the slagging structure of its head mainly contains plane, concave shape, convex, dark recessed middle heart-shaped four kinds of structure designs, and being provided with limbers, this limbers mainly adopts symmetrical center and side mode.These four kinds of typical structure designs, have the limitation that it uses.Flat design wide adaptability, major defect is that rate of penetration is relatively slow; Concave design is good in general middle incompetent bed result of use, but is not suitable with competent bed; Convex-surface type design election war is that rate of penetration is fast, but drill bit centering effect is poor, is not suitable with and is using the exigent occasion of the position degree in hole; Dark convex Center is only adapted to use at soft formation to have good effect.And the bore bit deslagging effect of four kinds of forms is all undesirable, thus have impact on its rock drilling drivage efficiency, and in use carbide button easily occurs falling tooth, broken teeth, falls block, the phenomenons such as crackle, reduce the application life of bore bit.
Utility model content
The purpose of this utility model is to provide a kind of novel quick streamlined rock drill bit, and ensure that bore bit is in drilling process, deslagging is unobstructed, effectively can improve cutting rate, and improves the application life of bore bit.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of novel quick streamlined rock drill bit, comprise steel body and the post tooth being located at steel body end face, blind hole is had in described steel body lower end, described steel body upper end is provided with the air vent of inclination, described air vent and described blind hole through, described steel body upper surface offers many grooves connected with air vent, is all communicated with at least one auxiliary tank between any two adjacent described grooves, described steel body sidewall offers some wall grooves, and the upper end of described arbitrary wall groove is at least communicated with an auxiliary tank.
Further, described steel body bottom is provided with impact step.
Further, described air vent is set to 2-4, and described air vent diameter is set to 9 ~ 16mm.
Further, described wall groove is obliquely installed, and between described wall groove inclined plane and described steel body center line, angle is set to 0 ° ~ 30 °.
Compared with prior art, the beneficial effects of the utility model are:
The utility model scientific structure design, simple, rationally, by Design assistant groove by mutually through for many grooves, more groove makes to decrease in bore bit drilling process the resistance with dike, and deslagging is smooth and easy in time, decrease repetition fragmentation, what effectively improve bore bit creeps into punching rate, and improves the application life of bore bit.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment one
Consult Fig. 1, Fig. 2 and Fig. 3, a kind of novel quick streamlined rock drill bit, comprise steel body 1 and post tooth 2, post tooth 2 adopts carbide alloy to make, and has blind hole 3 at steel body 1 lower center, and steel body 1 upper end has the air vent 4 of inclination, and this air vent 4 is through with blind hole 3; Steel body 1 upper surface is set to plane 5, annular chamfer 6 is provided with in plane 5 periphery, boring tooth 2 is evenly arranged on plane 5 and annular chamfer 6, plane 5 offers many grooves 7 connected with air vent 4, at least one auxiliary tank 8 is all communicated with between any two adjacent grooves 7, this auxiliary tank 8 is for by through for many grooves 7, and described steel body 1 sidewall offers some wall grooves 9, and the upper end of arbitrary wall groove 9 is at least connected with an auxiliary tank 8.
In the present embodiment, steel body 1 bottom is provided with and impacts step 10, is provided with many splines 11 in the appearance of steel body 1 middle part.Be provided with many splines 11 for connecting at impact step 10 external surface simultaneously.
Wherein many grooves 7 and auxiliary tank 8 connect and distribute ringwise, reduce resistance when creeping into, creep into brisk, can improve rate of penetration, make deslagging more smooth and easy simultaneously.
In addition, air vent 4 is set to 2-4, and air vent 4 diameter is set to 9 ~ 16mm.
Further, wall groove 9 is obliquely installed, and the angle between its inclined plane and steel body 1 center line is set to 0 ° ~ 30 °, is so more conducive to the discharge of ground-slag.
Embodiment two
Steel body 1 bottom is set to straight barrel type structure in the present embodiment, is provided with screw thread is used for connecting other elements in steel body 1 bottom.
The above embodiments are only preferred embodiment of the present utility model, can not limit interest field of the present utility model with this, and therefore, the equivalent variations done according to the utility model claim, still belongs to the scope that the utility model is contained.
