Abstract
The reaming bit of equipment is adopted in a kind of facing granite horizon mining equipment and hole, the front portion of this reaming bit is a guide cylinder, the middle part of this reaming bit is the rock drilling body that diameter is greater than guide cylinder, described guide cylinder front end is provided with some front Place teeth, and described rock drilling body front end edge circumference is evenly equipped with some reamer buttons.The utility model can be used for carrying out reaming to less hole, thus reaches and be comparatively communicated with between small holes, realizes the cutting of the stone materials such as granite, has reaming accurate positioning, long service life, be convenient to the advantages such as deslagging.
Description
Technical field
The utility model relates to a kind of stone hole mining equipment, and the reaming bit of equipment is adopted in a kind of facing granite horizon mining equipment and hole specifically.
Background technology
In order to realize protection and the destruction of minimizing to surface vegetation of ecological environment, for fully developing the mineral resources of high-quality, the mode that some developed countries start to adopt hole to adopt is exploited stone materials such as granite.But the external hole technology of adopting mainly contains several at present: high pressure waterjet, the marble that sawing is cut, stone matter is softer of restricting can also adopt chain arm to saw.These mode machine costs, cost of winning, technical requirements are all very high.Therefore one more economic, effective, reliable hole mining method is needed.If hole in a row is through cutting path can be connected into, just adopt for facing granite hole and open the new gate of a fan.Adopt general hole knockout to realize, in the process of punching continuously, being easily subject to the problems such as the interference of adjacent holes, human factor, cause training off, go here and there the phenomenon in hole, thus be difficult to be formed continuously and the hole communicated.
Utility model content
The utility model provides the reaming bit that equipment is adopted in a kind of facing granite horizon mining equipment and hole, its object is to solve in the process of punching continuously, easily trains off, goes here and there the problems such as hole.
The reaming bit of equipment is adopted in a kind of facing granite horizon mining equipment and hole, the front portion of this reaming bit is a guide cylinder, the middle part of this reaming bit is the rock drilling body that diameter is greater than guide cylinder, described guide cylinder front end is provided with some front Place teeth, and described rock drilling body front end edge circumference is evenly equipped with some reamer buttons.
Further, described rock drilling body point diameter is greater than rear end diameter.
Further, the front end of described rock drilling body is transition cambered surface low outside the height of inner side.
Further, the sidewall of described rock drilling body offers some ash pits.
Further, described guide cylinder front end is taper surface, and described front Place tooth is symmetrically set on this taper surface.
Further, described rock drilling body front end is provided with some delivery ports.
Further, described front Place tooth and reamer buttons are hard alloy spherical-teeth.
The utility model can be used for carrying out reaming to less hole, makes to be connected between Kong Yukong, forms cutting loop.Carried out the accurate location of holing by guide cylinder, then expand hole by rock drilling body.Guide cylinder and rock drilling body front end be provided with carbide alloy make before Place tooth, play the effect preventing guide cylinder from wearing and tearing, prevent aperture from diminishing, extend application life of reaming bit.Described rock drilling body point diameter is greater than rear end, contributes to waste residue and discharges backward, and the discharge of waste residue is also convenient in the design of described ash pit.In addition, this bearizing mechanism is provided with delivery port, can make the cooling water ejection passed into wherein, cool, produce high temperature to avoid bearizing mechanism and stone material to rub to bearizing mechanism.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Detailed description of the invention of the present utility model is as follows:
With reference to Fig. 1, the reaming bit of equipment is adopted in a kind of facing granite horizon mining equipment and hole, the front portion of this reaming bit is a guide cylinder 2, and described guide cylinder 2 front end is taper surface 20, this taper surface 20 is arranged with the front Place tooth 21 that some carbide alloy are made.The middle part of described reaming bit is rock drilling body 3, this rock drilling body 3 point diameter is greater than rear end diameter, the front end of described rock drilling body 3 is the low transition cambered surface 31 in high outside, inner side, and this rock drilling body 3 front end edge circumference is evenly equipped with reamer buttons 30 that some carbide alloy make and offers some delivery ports 310.The sidewall of rock drilling body 3 offers some ash pits 32.
With reference to Fig. 1, mode of occupation of the present utility model is, the common perforating mechanism interval of normal diameter is first used to open the some apertures of cutter, rock drilling campaign is carried out by actuating unit drive again with reaming bit described in the utility model, the diameter of described guide cylinder 2 is consistent with the diameter of described common perforating mechanism, this guide cylinder 2 enters in the aperture dug in advance, further aperture is expanded by rock drilling body 3 again, Kong Yukong is interconnected, achieve accurate punching, effectively prevent the phenomenon trained off.
Above are only detailed description of the invention of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
