Abstract
Disclosed is a diamond impregnated deflecting bit capable of effectively cutting center rocks at the bottom of holes, which is characterized in that a ribbed matrix and a central matrix are connected to a steel bit body, the matrixes are embedded with diamonds, circular water pores penetrate through the steel bit body at the center of the ribbed matrix, a fan-blade shaped water pore is arranged at the center of the matrix, and the fan-blade shaped cutting edge is embedded with diamonds. While the impregnated diamonds cut and break rocks, the impregnated diamonds around the fan-blade shaped water pore rotationally cut and break the center rocks along the circle center, and then washing fluid flows from the inner circle of the steel bit body to the bottom of the bit, thereby generating a stronger liquid washing force which carries rock cuttings up along the surrounding spacing of the drill bit, further avoiding being unfavorable for cutting rocks at the position of zero central linear velocity, and effectively breaking the center rocks at the bottom of the holes.
Description
Affiliated technical field
The utility model relates to a kind of impregnated with diamond deflecting bit.
Background technology
At present, the directional drilling technology develops rapidly, is widely used in the exploitation and the special engineering project of mineral exploration, exploitation of mineral resources, coal bed gas, and the deflecting bit important Cutting Rock instrument that is directional drilling, but, influence the drill bit guiding in the build-up process because the structural factor of deflecting bit own can't effectively be avoided center " dead point ", the centre rock can't be effectively broken, it is broken to cause bottom rock to repeat, and bit wear is serious, and rate of penetration reduces, prolong the duration, improved drilling cost.
Summary of the invention
Can't effectively solve the deficiency that the bit central linear velocity is zero position for overcoming existing deflecting bit, the utility model provides a kind of impregnated with diamond deflecting bit, this impregnated with diamond deflecting bit not only has guidance quality and detritus function, and to solve the bit central linear velocity be zero position, improves the efficient of broken centre rock.
The technical scheme that its technical problem that solves the utility model adopts is: in drill bit bottom, three flabellum shape otch are set on the mole of center, six plane ribs of uniform all around arrangement are at the center mole with inlay impregnated with diamond on six ribs on every side.When creeping into, central whole formula mole has good guidance, impregnated with diamond cuts broken centre rock around the flabellum shape otch, flushing liquor penetrates from flabellum shape otch and circular hydrophthalmia, carry portal bed rock powder and sillar, the cooling drill bit reaches that to solve in the drilling process guidance quality bad, the center rock is difficult for broken, produces the purpose of difficult problems such as little core.
The beneficial effects of the utility model are, in the directional drilling process, and center rock at the bottom of effective broken hole, cleaning hole bed rock powder and sillar, simple in structure.
Description of drawings
Fig. 1 is a drill bit chart at the bottom of of the present utility model;
Fig. 2 is the A-A1 section right view of the utility model Fig. 1;
1. rib carcasses among the figure, 2. drill steel body, 3. center carcass, 4. circular hydrophthalmia, 5. center flabellum shape hydrophthalmia.
The specific embodiment
In Fig. 1, rib carcass (1), center carcass (3) are connected on the drill steel body (2), rib carcass (1) and center carcass (3) are an integral body, mosaic gold hard rock in the carcass, circular hydrophthalmia (4) runs through the drill steel body (2) in the middle of the rib carcass (1), center flabellum shape hydrophthalmia (5) is at center carcass (3) center, and three flabellum shape otch are 120 degree angles each other and overlap flabellum shape incision mosaic gold hard rock with drill bit bottom circular diameter.Drill steel body (2) is supporting rib carcass (1) and center carcass (3) as shown in Figure 2, in the diamond cutting sword incision lithosome, drilling tool reverses and drives the drill bit rotation, impregnated with diamond cutting fractured rock, the drill bit outer edge has rib diamond carcass (1) to protect the footpath, center flabellum shape hydrophthalmia (5) impregnated with diamond on every side is along the broken center of center of circle rotary cutting rock, flushing liquor flows to the drill bit bottom by drill steel body (2) internal diameter, through three the circular hydrophthalmias in bottom (4), produce stronger flushing liquor pressure during center flabellum shape hydrophthalmia (5), cutting carring returns on the space all around along drilling tool, and the assurance landwaste is in time drained, prevent the repetition fragmentation, the cooling drill bit.
Claims (3)
1, a kind of impregnated with diamond deflecting bit, rib carcass, center carcass are attached on the drill steel body, and mosaic gold hard rock in the carcass, hydrophthalmia are arranged on drill steel body bottom, it is characterized in that: center flabellum shape hydrophthalmia is in carcass centre, center, flabellum shape incision mosaic gold hard rock.
2, according to the described impregnated with diamond deflecting bit of claim 1, it is characterized in that: circular hydrophthalmia runs through the drill steel body in the middle of the rib carcass, and center flabellum shape hydrophthalmia is 120 degree angles each other and overlaps with drill bit bottom circular diameter.
3, according to the described impregnated with diamond deflecting bit of claim 1, it is characterized in that: rib carcass and center carcass are for studding with adamantine monolithic.
