Abstract
The invention relates to a full-section compact bit, which comprises a bit installing seat and a bit main body, wherein the front end of the bit main body is provided with compact assemblies; each compact assembly comprises a welding seat and a compact; a plurality of inner and outer circles of compact assemblies are formed in the end surface of the bit main body; each circle of compact assemblies are in separated arrangement in the circumferential direction; the outermost circle of compact assemblies are positioned on the same circle; the compact assemblies at the inner circle are staggered and positioned at the inner side and the outer side of the corresponding circle; a drainage groove and water guide holes in symmetrical arrangement around the center are also formed in the bit main body; and the water guide holes and the peripheral surface of the bit main body are communicated through the drainage groove. The full-section compact bit has the advantages that the end part of the bit is provided with a plurality of groups of compact assemblies; the arrangement of the compact assemblies is reasonable; and the drilling efficiency of the bit is greatly improved.
Description
Technical field
The present invention relates to technical field of geological exploration, particularly drill bit.
Background technology
Drill bit is equipped with in geological drilling its front end of drilling tool used, in order to improve the hardness of drill bit, adopts diamond compact bit at present more, namely installs diamond compact in the front end of drill bit.In existing diamond compact bit, the structural configuration of diamond compact is reasonable not, cause drill bit to drill through efficiency lower.
Summary of the invention
The applicant, for the above-mentioned shortcoming of prior art, carries out studying and improving, and provides a kind of tunneling boring compact bit, compares traditional compact bit, substantially increase and drill through efficiency.
In order to solve the problem, the present invention adopts following scheme:
A kind of tunneling boring compact bit, comprise drill-bit installing seat and drill main body, the front end of drill main body is provided with composite sheet assembly, composite sheet assembly comprises welding base and composite sheet, described composite sheet assembly forms inside and outside multi-turn in the end face of drill main body, the composite sheet assembly of each circle is circumferentially arranged at interval, and the composite sheet assembly of outmost turns is on the circle of same place, and the composite sheet assembly staggering of inner ring is positioned at the inside and outside both sides of corresponding place circle; Described drill main body is also provided with the water-guiding hole be arranged symmetrically with around its center and drainage channels, and water-guiding hole is communicated with drill main body outer peripheral face by drainage channels.
Further improvement as technique scheme:
The side face of described drill main body is with around its center arrangement and outwardly boss, and the side of described boss is inlaid with alloy sheet.
The outer end outlet opening of described drainage channels is between adjacent described boss.
The cutting face, end of described drainage channels laminating composite sheet.
Angular range between the central axis of composite sheet assembly and the tangent line of its place circle is 8-12 °.
Technique effect of the present invention is:
In the present invention, the end of drill bit is provided with many group composite sheet assemblies, and composite sheet assembly adopts staggered Internal and external cycle to arrange, its connection and reasonable arrangement, and form all standing of bit face, what substantially increase drill bit drills through efficiency.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention.
In figure: 1, drill-bit installing seat; 2, drill main body; 3, composite sheet assembly; 310, cutting face, end; 4, water-guiding hole; 5, drainage channels.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, the tunneling boring compact bit of the present embodiment, comprise drill-bit installing seat 1 and drill main body 2, the front end of drill main body 2 is provided with composite sheet assembly 3, composite sheet assembly comprises welding base and composite sheet, composite sheet is diamond compact, composite sheet assembly 3 forms inside and outside multi-turn in the end face of drill main body 2, as shown in Figure 1, the composite sheet assembly 3 of each circle is circumferentially arranged at interval, the composite sheet assembly 3 of outmost turns is on the circle of same place, and the composite sheet assembly 3 of inner ring staggers and is positioned at the inside and outside both sides of corresponding place circle; Drill main body 2 is also provided with the water-guiding hole 4 and drainage channels 5 that are arranged symmetrically with around its center, water-guiding hole 4 is communicated with drill main body 2 outer peripheral face by drainage channels 5.The central axis of the relative drill main body 2 of water-guiding hole 4 is certain angle, and described angular range is 12-25 °, and when ensureing bit operation, shaft bottom smooth in water flow, reduces resistance, improves and drills through efficiency.
In the present invention, composite sheet assembly is inside and outside multi-turn and is staggeredly arranged, and during bit, the covering of composite sheet assembly is whole drills through end face, and it is high that it drills through efficiency.
The side face of drill main body 2 is with around its center arrangement and outwardly boss, and the side of boss is inlaid with alloy sheet, and alloy sheet is used for, to drill bit protection, preventing drill bit from wearing and tearing in boring procedure, ensureing that its bore diameter is constant.
As shown in Figure 1, the outer end outlet opening of drainage channels 5 is between adjacent boss, and drainage channels 5 is fitted the cutting face, end 310 of composite sheet, is easy to discharge the chip after drilling through.
Drill through efficiency for improving further, the angular range between the central axis of composite sheet assembly 3 and the tangent line of its place circle is 8-12 °.
Above illustrated embodiment is better embodiment of the present invention, only be used for conveniently the present invention being described, not any pro forma restriction is done to the present invention, have in any art and usually know the knowledgeable, if do not depart from the present invention carry in the scope of technical characteristic, utilize the Equivalent embodiments that the done local of disclosed technology contents is changed or modified, and do not depart from technical characteristic content of the present invention, all still belong in the scope of the technology of the present invention feature.
