Abstract
The utility model discloses a drill bit is used in probing, including the body of rod, bit body, cutter body, heliciform chip removal piece, the bit body is coniformly, the body of rod with bit body integrated into one piece, the cutter body is installed on the body of rod, the cutter body with the axial vertical ground of the body of rod sets up, heliciform chip removal piece is installed on the body of rod, the one end of heliciform chip removal piece with cutter body welded fastening. The utility model discloses a drill bit is used in probing, simple structure is particularly useful for creeping into of stereoplasm stratum, has row's piece, the effect of row's rubble on better ground, has improved and has crept into efficiency.
Description
Technical field
The utility model relates to bit technique field, is specifically related to a kind of probing drill bit.
Background technology
At present, probing drill bit is only applicable to soft to middle hardness uniform formation, it is not suitable with creeping into of hardpan, when boring hardpan, rate of penetration and drilling depth are low, and stability of bit is poor, in drilling process, owing to landwaste can not be discharged in time, and cause and landwaste returns and is detained, thus reduce drill speed; When especially running into the more stratum of rubble, creep into speed and can be subject to serious impact.
Practical novel content
The utility model is intended at least solve one of the problems of the prior art.
The purpose of this utility model is to propose a kind of probing drill bit.
Probing drill bit according to embodiment of the present utility model, comprises the body of rod, frame of the bit, cutter hub, spirrillum chip removing sheet, and described frame of the bit is circular cone shape, and the described body of rod and described frame of the bit are one-body molded; Described cutter hub is arranged on the described body of rod, arranging of described cutter hub and the described body of rod axial vertically; Described spirrillum chip removing sheet is arranged on the described body of rod, and one end and the described cutter hub of described spirrillum chip removing sheet are welded and fixed.
According to an embodiment of the present utility model, between the described body of rod and described frame of the bit, it is formed with junk slot.
According to an embodiment of the present utility model, the degree of depth of described junk slot is 5-8mm.
According to an embodiment of the present utility model, the described body of rod is also provided with installation groove.
According to an embodiment of the present utility model, the described body of rod and frame of the bit integrally casting are shaping.
According to an embodiment of the present utility model, the end coated of described frame of the bit has hard alloy abrasion-resistant layer.
The utility model has following advantage relative to prior art:
Probing drill bit disclosed in the utility model, comprise the body of rod, frame of the bit, cutter hub, spirrillum chip removing sheet, frame of the bit is arranged to circular cone shape, and it is one-body molded with the body of rod, frame of the bit can be made to be more prone to ground auger and to enter geology depths, and frame of the bit and the one-body molded rigidity that can improve drill bit entirety of the body of rod, there is the phenomenon of fracture when preventing from creeping into hardpan between frame of the bit and the body of rod; Cutter hub is arranged on the body of rod, and the axis making cutter hub be perpendicular to the body of rod is arranged, and can ensure that cutter hub can bear bigger moment of flexure like this; Spirrillum chip removing sheet is arranged on the body of rod, and one end and cutter hub are welded and fixed, it is possible to strengthen the strength of joint between cutter hub and the body of rod further, and chip or rubble can be discharged by spirrillum chip removing sheet in time, it is to increase drilling efficiency.
Probing drill bit disclosed in the utility model, structure is simple, is particularly useful for creeping into of hardpan, have row's chip preferably, row's rubble effect, it is to increase drilling efficiency.
Accompanying drawing explanation
The following drawings is only intended to be done by the utility model schematic description and interpretation, does not limit scope of the present utility model. Wherein:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is left view;
In figure: the 1-body of rod, 2-frame of the bit, 3-cutter hub, 4-spirrillum chip removing sheet, 5-junk slot, 6-installs groove.
Embodiment
Below in conjunction with drawings and Examples, set forth the utility model further. In the following detailed description, only some one exemplary embodiment of the present utility model is described by the mode of explanation. Undoubtedly, the those of ordinary skill of this area is not it is to be appreciated that when deviateing spirit and scope of the present utility model, it is possible to described embodiment revised by various different mode. Therefore, accompanying drawing and description are being explanation property 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 utility model embodiment, comprise the body of rod 1, frame of the bit 2, cutter hub 3, spirrillum chip removing sheet 4, frame of the bit 2 is arranged to circular cone shape, frame of the bit 2 can be made to be more prone to ground auger and to enter geology depths, and frame of the bit 2 is one-body molded with the body of rod 1, as preferably, frame of the bit 2 is shaping with the body of rod 1 integrally casting, the rigidity of drill bit entirety can be improved like this, the phenomenon of fracture occurs between frame of the bit 2 and the body of rod 1 when preventing from creeping into hardpan;
Being arranged on the body of rod 1 by cutter hub 3, cutter hub 3 is axial with the body of rod 1 to be arranged vertically, can ensure that cutter hub can bear bigger moment of flexure like this, it is possible to be more suitable for and creep into hardpan;
Spirrillum chip removing sheet 4 is arranged on the body of rod 1, and one end of spirrillum chip removing sheet and cutter hub 3 are welded and fixed, the strength of joint between cutter hub 3 and the body of rod 1 can be strengthened further, and chip or rubble can be discharged by spirrillum chip removing sheet 4 in time, it is to increase drilling efficiency.
Further, being formed with junk slot 5 between the body of rod 1 and frame of the bit 2, the part chip that junk slot 5 produces after being cut by cutter hub 3 and rubble play shock absorption, prevent producing card in the overall drilling process of drill bit stagnant.
As preferably, the degree of depth of junk slot 5 is 5-8mm, more specifically, the junk slot degree of depth disclosed in the present embodiment is 6mm, better to chip and rubble shock absorption.
Further, the body of rod 1 is also provided with groove 6 is installed, groove 6 is installed and can conveniently the body of rod 1 and miser be installed.
Again further, the end coated at frame of the bit 2 has hard alloy abrasion-resistant layer, the end of frame of the bit 2 can be made so more wear-resisting, be more suitable for creeping into of hardpan, and can improve the work-ing life of frame of the bit 2.
The foregoing is only the schematic embodiment of the utility model, it does not mean to limit scope of the present utility model. The technician of any this area, equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.
