Abstract
Conducive to the diamond compact coring bit of draining during drilling, including steel body and cutting tooth;Steel body is in socket type, and one end is the first end being connected with drilling equipment, and the other end is the second end being connected with cutting tooth;Cutting tooth has 35 groups, and each group cutting tooth is distributed on the second end of steel body in a ring;One group of cutting tooth includes a cutting tooth A and at least one cutting tooth B, cutting tooth A are fixed on the end face of the second end of steel body, and cutting tooth B is fixed on the lateral wall of the second end of steel body, and with cutting tooth A in the axial direction close to;Steel body is equipped with drain chamber in the region between adjacent cutting tooth A.The utility model has the advantage of drill bit abrasion resistance is good, and when work takes stratum core convenient, and gauge effect is good, not water blockoff, is not easy bit freezing.
Description
Technical field
The utility model is related to technical field of geological exploration, particularly a kind of diamond compact for being conducive to draining during drilling
Coring bit.
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;Cutting tooth have it is multiple, it is equidistant respectively to be welded on a side end face of steel body, set in the steel body between adjacent cutting tooth
There is the drain chamber that semicircular in shape is recessed.
Shortcoming existing for above-mentioned diamond compact coring bit is:1st, the quantity of cutting tooth is usually no less than
6 efficiency that just can guarantee cutting rock mass, all cutting tooth equidistant arrangements are on one side end face of steel body, when the quantity of cutting tooth
When being 6 or 6 or more, the distance between adjacent cutting tooth is relatively near, and the size for leading to drain chamber is smaller relative to steel body,
The phenomenon that water blockoff is susceptible in drilling process.2nd, the cutting face of cutting tooth front end (defines cutting tooth one towards drain chamber
Face is cutting face) it is rounded, without sharp corner angle, although with good wear-resisting property, 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 for being conducive to draining during drilling
Composite sheet coring bit, it is smaller that it solves existing diamond compact coring bit drain chamber size, is unfavorable for draining
The problem of, also solve the existing diamond compact coring bit drilling slow problem of ruler.
The technical solution of the utility model is:Conducive to the diamond compact coring bit of draining during drilling, including steel body
And cutting tooth;Steel body is in socket type, and one end is the first end being connected with drilling equipment, and the other end is is connected with cutting tooth
Second end;
Cutting tooth has 3-5 groups, and each group cutting tooth is distributed on the second end of steel body in a ring;One group of cutting tooth is cut including one
Tooth A and at least one cutting tooth B are cut, cutting tooth A is fixed on the end face of the second end of steel body, and cutting tooth B is fixed in steel body
On the lateral wall of second end, and with cutting tooth A in the axial direction close to;
Steel body is equipped with drain chamber in the region between adjacent cutting tooth A.
The further technical solution of the utility model is:The front end of each cutting tooth A and the rear end phase of adjacent cutting tooth A
It is right;The front end is cutting tooth A close to one end of grinding surface, and the rear end is the other ends of the cutting tooth A far from grinding surface;Each
The front end of cutting tooth B is opposite with the rear end of adjacent cutting tooth B;The front end is cutting tooth B close to one end of grinding surface, after described
It holds as the other ends of the cutting tooth B far from grinding surface.
Further technical solution is the utility model:Cutting tooth has three groups, and two are included in one group of cutting tooth along axis
To the cutting tooth B of parallel arrangement, the grinding surface of cutting tooth B is equipped with transversal crack.
The further technical solution of the utility model is:Drain chamber semicircular in shape.
The utility model has the following advantages that compared with prior art:
1st, drill bit abrasion resistance is good, and when work takes stratum core convenient, and gauge effect is good, not water blockoff, is not easy bit freezing.
2nd, due to the double change of tooth form and drill bit structure, working face resistance smaller, penetration rate greatly improves.
3rd, it is competing to greatly improve market for leftover pieces of the drill bit outer fractionlet for full wafer, recycling, cost reduction
Strive power.
The utility model is further described below in conjunction with figure and embodiment.
Description of the drawings
Fig. 1 is the dimensional structure diagram of the utility model;
Fig. 2 is the structure diagram of the utility model;
Fig. 3 is the vertical view of Fig. 2.
