Description
Technical field
This utility model relates to technical field of geological exploration, particularly to drill bit.
Background technology
Its front end of drilling tool used by geological drilling is equipped with drill bit, in order to improve the hardness of drill bit, uses diamond compact at present more
Drill bit, i.e. installs diamond compact in the front end of drill bit.In existing diamond compact bit, the knot of diamond compact
Structure is arranged not reasonable, causes drilling through of drill bit inefficient.
Utility model content
The applicant, for the disadvantages mentioned above of prior art, studies and improves, it is provided that a kind of tunneling boring compact bit, phase
The traditional compact bit of ratio, substantially increases and drills through efficiency.
In order to solve the problems referred to above, this utility model following scheme of employing:
A kind of tunneling boring compact bit, including drill-bit installing seat and drill main body, the front end of drill main body is provided with composite sheet group
Part, composite sheet assembly includes welding base and composite sheet, and described composite sheet assembly forms inside and outside multi-turn, often in the end face of drill main body
The composite sheet assembly of one circle is circumferentially spaced layout, and the composite sheet assembly of outmost turns is on the circle of same place, inner ring
Composite sheet assembly staggering be positioned at inside and outside the circle of corresponding place；It is additionally provided with on described drill main body around its centrosymmetry cloth
The water-guiding hole put and drainage channels, water-guiding hole is connected by drainage channels with drill main body outer peripheral face.
Further improvement as technique scheme:
The side face of described drill main body is with around its center arrangement outwardly boss, and the side of described boss is inlaid with conjunction
Gold plaque.
The outer end outlet of described drainage channels is between adjacent described boss.
The cutting face, end of described drainage channels laminating composite sheet.
Angular range between central axis and the tangent line of its place circle of composite sheet assembly is 8-12 °.
Of the present utility model have the technical effect that
In this utility model, the end of drill bit is provided with many group composite sheet assemblies, and composite sheet assembly uses staggered Internal and external cycle to arrange,
Its connection and reasonable arrangement, forms all standing of bit face, and substantially increase drill bit drills through efficiency.
Accompanying drawing explanation

Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further.
As shown in Figure 1, Figure 2 and Figure 3, the tunneling boring compact bit of the present embodiment, including drill-bit installing seat 1 and drill bit master
Body 2, the front end of drill main body 2 is provided with composite sheet assembly 3, and composite sheet assembly includes welding base 30 and composite sheet 31, compound
Sheet 31 is diamond compact, and composite sheet assembly 3 forms inside and outside multi-turn in the end face of drill main body 2, as in figure 2 it is shown, each
The composite sheet assembly 3 of circle is circumferentially spaced layout, and the composite sheet assembly 3 of outmost turns is on the circle of same place, interior
The composite sheet assembly 3 of circle staggers and is positioned at inside and outside the circle of corresponding place；It is additionally provided with around its centrosymmetry on drill main body 2
The water-guiding hole 4 arranged and drainage channels 5, water-guiding hole 4 is connected by drainage channels 5 with drill main body 2 outer peripheral face.Water-guiding hole 4
The central shaft of drill main body 2 is certain angle relatively, and described angular range is 12-25 °, it is ensured that during bit operation, shaft bottom
Smooth in water flow, reduces resistance, improves and drills through efficiency.
In this utility model, composite sheet assembly is inside and outside multi-turn and is staggeredly arranged, and during bit, composite sheet assembly covers
Whole drilling through end face, it is high that it drills through efficiency.
The side face of drill main body 2 is with around its center arrangement outwardly boss, and the side of boss is inlaid with alloy sheet 6,
Alloy sheet 6, for protecting drill bit, prevents drill bit from wearing and tearing in boring procedure, it is ensured that its bore diameter is constant.
As shown in Figure 2 and Figure 3, the outer end outlet of drainage channels 5 is between adjacent boss, and drainage channels 5 laminating is multiple
Close the cutting face, end 310 of sheet 31, it is easy to discharge the chip after drilling through.
Efficiency is drilled through, the angular range between central axis and the tangent line of its place circle of composite sheet assembly 3 for improving further
For 8-12 °.
Embodiment provided above is better embodiment of the present utility model, is only used for convenient explanation this utility model, not to this
Utility model makees any pro forma restriction, has usually intellectual in any art, if new without departing from this practicality
In the range of the carried technical characteristic of type, the equivalence utilizing the done local of this utility model disclosed technology content to change or modify is real
Execute example, and without departing from technical characteristic content of the present utility model, all still fall within the range of this utility model technical characteristic.
