Abstract
The invention discloses a drill bit of drilling. The drill bit for drilling comprises a rod body, a drill bit body, a cutter body and a spiral chip removing plate; the drill bit body is shaped like a circular cone, and the rod body and the drill bit body are integrally formed; the cutter body is installed on the rod body, and the cutter body is arranged to be perpendicular to the rod body in the axial direction; the spiral chip removing plate is installed on the rod body, and one end of the spiral chip removing plate is fixed with the cutter body in a welded mode. The drill bit for drilling is simple in structure and especially suitable for drilling of hard strata, the better effects of removing chips and broken stones are achieved, and the drilling efficiency is improved.
Description
Technical field
The present invention relates to bit technique field, be specifically related to a kind of probing drill bit.
Background technology
At present, probing drill bit is only applicable to soft to middle hardness homogeneous formation, be not suitable with creeping into of hardpan, bore hardpan time, rate of penetration and drilling depth low, stability of bit is poor, in drilling process, because landwaste can not be discharged in time, and cause and landwaste returns and is detained, thus reduce rate of penetration; When especially running into the more stratum of rubble, creeping into speed can be had a strong impact on.
Summary of the invention
The present invention is intended at least solve one of the problems of the prior art.
The object of the invention is to propose a kind of probing drill bit.
Probing drill bit according to an embodiment of the invention, comprise the body of rod, bit body, cutter hub, helical form chip removing sheet, described bit body is coniform, the described body of rod and described bit body one-body molded; Described cutter hub is arranged on the described body of rod, and the axis of described cutter hub and the described body of rod is vertically arranged; Described helical form chip removing sheet is arranged on the described body of rod, and one end and the described cutter hub of described helical form chip removing sheet are welded and fixed.
According to one embodiment of present invention, chip area is formed with between the described body of rod and described bit body.
According to one embodiment of present invention, the degree of depth of described chip area is 5-8mm.
According to one embodiment of present invention, the described body of rod is also provided with mounting groove.
According to one embodiment of present invention, the described body of rod and bit body integrally casting shaping.
According to one embodiment of present invention, the end coated of described bit body has hard alloy abrasion-resistant layer.
The present invention has following advantage relative to prior art:
Probing drill bit disclosed by the invention, comprise the body of rod, bit body, cutter hub, helical form chip removing sheet, bit body is arranged to coniform, and it is one-body molded with the body of rod, bit body can be made to pierce geology depths more easily, and bit body and the one-body molded rigidity that can improve drill bit entirety of the body of rod, there is the phenomenon ruptured when preventing from creeping into hardpan between bit body and the body of rod; Cutter hub is arranged on the body of rod, and cutter hub is arranged perpendicular to the axis of the body of rod, can ensure that cutter hub can bear larger moment of flexure like this; Helical form chip removing sheet is arranged on the body of rod, and one end and cutter hub are welded and fixed, and can strengthen the bonding strength between cutter hub and the body of rod further, and chip or rubble can be discharged by helical form chip removing sheet in time, improve drilling efficiency.
Probing drill bit disclosed by the invention, structure is simple, is particularly useful for creeping into of hardpan, has row's chip preferably, the effect of row's rubble, improves drilling efficiency.
Accompanying drawing explanation
The following drawings is only intended to schematically illustrate the present invention and explain, not delimit the scope of the invention.Wherein:
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is left view;
In figure: the 1-body of rod, 2-bit body, 3-cutter hub, 4-helical form chip removing sheet, 5-chip area, 6-mounting groove.
Detailed description of the invention
Below in conjunction with drawings and Examples, set forth the present invention further.In the following detailed description, the mode only by illustrating describes some one exemplary embodiment of the present invention.Undoubtedly, those of ordinary skill in the art can recognize, when without departing from the spirit and scope of the present invention, can revise by various different mode to described embodiment.Therefore, accompanying drawing is illustrative with being described in essence, instead of for limiting the protection domain of claim.
Shown in composition graphs 1 and Fig. 2, according to the probing drill bit of the embodiment of the present invention, comprise the body of rod 1, bit body 2, cutter hub 3, helical form chip removing sheet 4, bit body 2 is arranged to coniform, bit body 2 can be made to pierce geology depths more easily, and bit body 2 is one-body molded with the body of rod 1, as preferably, bit body 2 is shaping with the body of rod 1 integrally casting, the rigidity of drill bit entirety can be improved like this, the phenomenon ruptured occurs between bit body 2 and the body of rod 1 when preventing from creeping into hardpan;
Be arranged on by cutter hub 3 on the body of rod 1, cutter hub 3 is axially vertically arranged with the body of rod 1, can ensure that cutter hub can bear larger moment of flexure like this, can be more suitable for and creep into hardpan;
Helical form chip removing sheet 4 is arranged on the body of rod 1, and one end of helical form chip removing sheet and cutter hub 3 are welded and fixed, can strengthen the bonding strength between cutter hub 3 and the body of rod 1 further, and chip or rubble can be discharged by helical form chip removing sheet 4 in time, improve drilling efficiency.
Further, be formed with chip area 5 between the body of rod 1 and bit body 2, chip area 5 pairs of cutter hubs 3 cut the part chip of rear generation and rubble plays cushioning effect, prevent from producing clamping stagnation in the overall drilling process of drill bit.
As preferably, the degree of depth of chip area 5 is 5-8mm, and more specifically, the chip area degree of depth disclosed in the present embodiment is 6mm, better to chip and rubble cushioning effect.
Further, the body of rod 1 is also provided with mounting groove 6, the body of rod 1 and rig can be installed by mounting groove 6 easily.
Again further, there is hard alloy abrasion-resistant layer in the end coated of bit body 2, the end of bit body 2 can be made so more wear-resisting, be more suitable for creeping into of hardpan, and the application life of bit body 2 can be improved.
The foregoing is only the schematic detailed description of the invention of the present invention, and be not used to limit scope of the present invention.Any those skilled in the art, equivalent variations done under the prerequisite not departing from design of the present invention and principle and amendment, all should belong to the scope of protection of the invention.
