Abstract
A drill bit of a high-wind-pressure impacter comprises a drill bit body, wherein multiple layers of stepped tooth surfaces are arranged on the end surface of the drill bit body, the tooth surfaces are annularly raised outwards around the center of the drill bit body, the tooth surface of the edge of the drill bit body sinks, alloy teeth are arranged on the tooth surfaces, multiple primary water channels are formed in the edge of the drill bit body, secondary water channels connected with the primary water channels are formed in the drill bit body, the secondary water channels are communicated with the center of the end surface of the drill bit body and the primary water channels, each primary water channel is communicated with a primary slag discharge groove, multiple secondary slag discharge grooves are further formed in the edge of the drill bit body, and the primary slag discharge grooves and the secondary slag discharge grooves enable the end surface of the drill bit body to be connected with a water discharging end. The drill bit of the high-wind-pressure impacter has the advantages of being simple in structure, long in service life, good in abrasion resistance, good in slag discharge effect, capable of obviously improving the phenomena of breakage and abrasion of the teeth, and the like, and is applicable to rock drilling tools used in the fields of geological mining, hydroelectric power, highways, railways, water wells, oil wells, terrestrial heat and the like.
Description
Technical field
The utility model relates to a kind of high-wind pressure impactor drill bit.
Background technology
Along with the develop rapidly of the development of the national economy, in the process that pulls the national economic development for infrastructure, in bore operation, use a kind of fast, efficient, stable, economy, long drill bit of life-span becomes problem anxious to be resolved at present.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of simple in structure, long service life, and deslagging is effective, the broken fireballing high-wind pressure impactor drill bit of rock.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of high-wind pressure impactor drill bit, comprise drill body, the end face of described drill body is provided with the flank of tooth of multi-step formula, the described flank of tooth is with the center lifting laterally ringwise successively of described drill body, the flank of tooth at described drill body edge sinks, the described flank of tooth is provided with carbide button, the edge of described drill body is provided with multiple main tanks, described drill body is provided with the secondary tank being connected with described main tank, described secondary tank is communicated with center and the main tank of described drill body end face, each described main tank is communicated with a main ash pit respectively, on the edge of described drill body, be also provided with multiple secondary ash pits, described main ash pit is connected the end face of described drill body with secondary ash pit with discharge ends.
On the end face of described drill body, be evenly provided with three main tanks and three secondary tanks corresponding with described main tank, described secondary ash pit is arranged between two main rhones.
The end of described drill body is provided with spline and is connected with impactor.
Owing to adopting such scheme, this apparatus structure is simpler, and lengthen application life, and abrasion resistance is strengthened, and the possibility of fracture reduces, and makes drill bit penetration rate when being hit energy faster, and efficiency is higher, adapts to various bad border operations.
In sum, the utlity model has simple in structure, long service life, abrasion resistance is good, deslagging successful, the fracture wear situation of tooth such as obviously can improve at the advantage, the rock drill that the fields such as applicable and ore deposit, ground, water power, highway, railway, well, oil well, underground heat are used.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In accompanying drawing, 1-flank of tooth, 2-secondary tank, 3-secondary ash pit, 4-carbide button, 5-main water hole, 6-main tank, 7-main ash pit, 8-spline
