Abstract
The invention discloses a drill bit with spiral lip surfaces. The drill bit comprises a drill bit body, a plurality of conical spiral carcasses, spiral water gaps and sector blocks. The conical spiral carcasses are disposed on the drill bit body in a surrounded manner. The sector blocks are disposed on the conical spiral carcasses. The spiral water gaps are formed among the conical spiral carcasses and are of a rightward spiral single-head shape and a multi-head spiral shape. The curve surface, forming a core part, of the each sector block and the curve surface, forming a hole wall part, of the sector block are located on a plane with the radius being R. The drill bit with the spiral lip surfaces has the advantages that various rocks can be crushed during drilling under different rock geological condition, stratum drilling application range of the drill bit is increased, friction force is lowered, radiation is facilitated, abnormal abrasion is avoided, complex situations are avoided, drilling speed and drill bit size are increased, accidents such as drill bit burning and jamming are reduced, and drill bit service life is prolonged.
Description
Technical field
The invention belongs to drill bit structure design field, be specifically related to a kind of spiral labial surface drill bit.
Background technology
Along with national economy is fast-developing, the demand of mineral resources is increased sharply, strengthen and look for ore deposit dynamics to bring into schedule.Diamond bit has the advantage that drilling depth is many, rate of penetration is fast, so being widely used in core drilling.Further investigate in terms of technique, material and structure etc. for these the most many research worker.Geological exploration field hard-rock boring selects diamond-impregnated bit mostly at present; existing diamond bit is unreasonable due to the design of its structure; in use detritus position is vulnerable to the grinding loss of rock and the erosion abrasion of coolant; usually there will be rock dust to be difficult to discharge; row's powder weak effect, heat is concentrated weak heat-dissipating, is easily generated the accident such as the burning of bits, bit freezing; directly affects construction speed and production cost, the life-span is substantially reduced.
Summary of the invention
The technical problem to be solved in the present invention is, for existing drill bit above shortcomings, it is provided that a kind of spiral labial surface drill bit, reduce frictional force and be beneficial to heat radiation, it is to avoid heel and toe wear, improving rate of penetration and footage per bit, reduce the accidents such as burning of bits bit freezing, improve bit life.
The present invention solves that above-mentioned technical problem be the technical scheme is that
A kind of spiral labial surface drill bit, it is made up of bit body, coniform spiral carcass, the helical form mouth of a river and secter pat, described coniform spiral carcass includes several, is circumferentially positioned on bit body, described secter pat is arranged on coniform spiral carcass, the described helical form mouth of a river is arranged between coniform spiral carcass, and it is on the Surface of Sphere of R that the curved surface of curved surface and formation wall portion that described secter pat forms rock core part is positioned at a radius.
By such scheme, described coniform spiral carcass is cone shape, and the helical form mouth of a river is dextrorotation single head or multi-head spiral shape.
The operation principle of the present invention: coniform spiral carcass can ensure that secter pat front portion is not hit, by rock fracture fractured rock in drilling process；It is on the Surface of Sphere of R that the curved surface of curved surface and formation wall portion that the secter pat of drill bit forms rock core part is positioned at a radius, bit operation part radiating rate can be increased, reduce frictional force, centralized heat energy is not produced in the secter pat center and curvature portion of drill bit, meanwhile, the helical form mouth of a river is conducive to rock dust to discharge rapidly below drill bit labial surface.Additionally, in the case of the short time at the bottom of hole stops supply flushing liquor, the effect of screw pump can be played in the helical form mouth of a river, it is ensured that produce microcirculation at the bottom of hole, it is to avoid the drill bit burning of bits, it is to avoid drill bit clip in drilling process.
Compared with prior art, the invention has the beneficial effects as follows: spiral labial surface drill bit uses the structure design of spiral labial surface, various rocks can be crushed under the conditions of creeping into different rock geology, increase drill bit and creep into the range on stratum, reduce frictional force and be beneficial to heat radiation, it is to avoid heel and toe wear, prevent complex situations, thus improve rate of penetration and footage per bit, reduce the accidents such as burning of bits bit freezing, improve bit life.
Accompanying drawing explanation
Fig. 1 is the structural representation of spiral labial surface drill bit of the present invention；
In figure, 1-bit body, 2-coniform spiral carcass, the 3-helical form mouth of a river, 4-secter pat.
Detailed description of the invention
The present invention is described in detail with embodiment below in conjunction with the accompanying drawings.
With reference to shown in Fig. 1, spiral labial surface drill bit of the present invention, it is made up of bit body 1, coniform spiral carcass 2, the helical form mouth of a river 3 and secter pat 4, described coniform spiral carcass 2 includes several, is circumferentially positioned on bit body 1, described secter pat 4 is arranged on coniform spiral carcass 2, the described helical form mouth of a river 3 is arranged between coniform spiral carcass 2, and it is on the Surface of Sphere of R that the curved surface of curved surface and formation wall portion that described secter pat 4 forms rock core part is positioned at a radius.
Described coniform spiral carcass 2 is in cone shape, and the helical form mouth of a river 3 is in dextrorotation single head or multi-head spiral shape.
Spiral labial surface drill bit of the present invention is as follows in shaft bottom work process:
Bit body 1 is threadedly attached on basket, arrive down at the bottom of hole, cooling drill bit, the flushing liquor of discharge rock dust, flowing to below the secter pat 4 of coniform spiral carcass 2 of drill bit along drill string by the helical form mouth of a river 3, secter pat 4 carries and under the effect of moment of torsion at axle, interacts with hole bed rock stone, fractured rock, in this case, coniform spiral carcass 2 can ensure that secter pat 4 front portion is not hit in drilling process, by rock fracture fractured rock；It is on the Surface of Sphere of R that the curved surface of curved surface and formation wall portion that the secter pat 4 of drill bit forms rock core part is positioned at a radius, bit operation part radiating rate can be increased, reduce frictional force, centralized heat energy is not produced in the secter pat center and curvature portion of drill bit, meanwhile, the helical form mouth of a river 3 is conducive to rock dust to discharge rapidly below drill bit labial surface.
Additionally, in the case of the short time at the bottom of hole stops supply flushing liquor, the effect of screw pump can be played in the helical form mouth of a river 3, it is ensured that produce microcirculation at the bottom of hole, it is to avoid the drill bit burning of bits, it is to avoid drill bit clip in drilling process.
The above-described presently preferred embodiments of the present invention that is only, the interest field that certainly can not limit the present invention with this, therefore change according to the equivalence that scope of the present invention patent is made, still belong to protection scope of the present invention.
