Abstract
Convenient for the diamond compact coring bit of drilling depth, including steel body and cutting tooth；Steel body is in sleeve shaped, and one end is drilling equipment connecting pin, and the other end is cutting tooth connecting pin；Cutting tooth have it is multiple, it is uniformly distributed in a ring respectively and be welded on a side end face of steel body；The cutting face of tooth ends is cut in sector.Cutting tooth is column of the radial section in sector, and the end face of the cutting tooth connecting pin of cambered surface and steel body on side wall is affixed, and the intersection of two planes on side wall is equipped with cutting rib；The sector is the closed figure surrounded by a camber line and two straight lines.The drill bit of the utility model is greatly improved due to the change of cutting tooth tooth form, working face (i.e. cutting face) resistance smaller, penetration rate.
Description
Technical field
The utility model is related to technical field of geological exploration, especially a kind of diamond compact core drills convenient for drilling depth
Head.
Background technology
In geological prospecting, situations such as to grasp earth formation, mineral resources distribution, need to obtain by core-drilling relevant
Matter data.
Drill bit is the critical component of drilling equipment, should have the characteristics that intensity is high, service life is long.Bit performance it is good
It is bad, it is directly related to drilling efficiency and drilling cost.
The existing diamond compact coring bit for being commonly used in core-drilling includes steel body and cutting tooth；Steel body is in set
Tubular, one end are drilling equipment connecting pin, and the other end is cutting tooth connecting pin；Cutting tooth have it is multiple, respectively it is equal in a ring
Cloth is welded on the end face of cutting tooth connecting pin of steel body；Steel body is equipped with recessed to drilling equipment connecting pin between adjacent cutting tooth
Sunken drain chamber.
Shortcoming is existing for above-mentioned diamond compact coring bit, the cutting face (definition of cutting tooth front end
The one side of cutting tooth towards drain chamber is cutting face) rounded, not sharp corner angle, although having good wearability
Can, but it is slower to bore penetration rate.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, and provide a kind of diamond compact convenient for drilling depth
Coring bit.It solves the problems, such as that existing diamond compact coring bit drilling ruler is slow-footed.
The technical solution of the utility model is：Convenient for the diamond compact coring bit of drilling depth, including steel body and cutting
Tooth；Steel body is in sleeve shaped, and one end is drilling equipment connecting pin, and the other end is cutting tooth connecting pin；Cutting tooth have it is multiple, point
It is evenly distributed with and is welded on a side end face of steel body in a ring；The cutting face of tooth ends is cut in sector.
The further technical solution of the utility model is：Cutting tooth is radial section in fan-shaped column, on side wall
Cambered surface and steel body cutting tooth connecting pin end face it is affixed, the intersections of two planes on side wall is equipped with cutting rib；Institute
It is the closed figure surrounded by a camber line and two straight lines to state sector.
Further technical solution is the utility model：The rear end of cutting tooth be equipped with diamond shape inclined-plane, diamond shape inclined-plane with cut
Two on flank wall planes are cut to be separately connected.
The further technical solution of the utility model is：The quantity of cutting tooth is six.
The utility model has the following advantages that compared with prior art：
The drill bit of the utility model is due to the change of cutting tooth tooth form, working face (i.e. cutting face) resistance smaller, drilling depth
Speed greatly improves.
The utility model is further described below in conjunction with figure and embodiment.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the vertical view of Fig. 1.
Specific implementation mode
Embodiment 1：
As shown in Figure 1, 2, it is convenient for the diamond compact coring bit of drilling depth, including steel body 1 and cutting tooth 2.
Steel body 1 is in sleeve shaped, and one end is drilling equipment connecting pin, and the other end is cutting tooth connecting pin.
There are six cutting tooths 2, is evenly distributed with and is welded on the end face of cutting tooth connecting pin of steel body 1 in a ring respectively, cuts
The cutting face 21 of 2 end of tooth is in sector.The sector is the closed figure surrounded by a camber line and two straight lines.Cutting tooth 2
It is in fan-shaped column for radial section, the cambered surface and the end face of the cutting tooth connecting pin of steel body 1 on side wall are welded and fixed,
The intersection of two planes on side wall is equipped with cutting rib 22.
It is preferred that steel body 1 is equipped with the drain chamber 11 for connecting concave end to drilling equipment between adjacent cutting tooth 2.
It is preferred that the rear end (rear end is one end far from cutting face 21) of cutting tooth 2 is equipped with diamond shape inclined-plane 23, diamond shape is oblique
Face 23 is separately connected with two planes on 2 side wall of cutting tooth.
