Description
Technical field
The present invention relates to technical field of geological exploration, particularly a kind of diamond compact coring for being beneficial to draining during drilling
Drill bit.
Background technology
In geological prospecting, it is necessary to which passing through core-drilling obtains related ground situations such as to grasp earth formation, mineral resources distribution
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 connected 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.
Weak point existing for above-mentioned diamond compact coring bit is：1st, the quantity of cutting tooth is generally no less than
6 efficiency that just can guarantee that cutting rock mass, all cutting tooth equidistant arrangements are on the side end face of steel body one, when the quantity of cutting tooth
For 6 or more than 6 when, the distance between adjacent cutting tooth is relatively near, causes the size of drain chamber smaller relative to steel body,
Easily occurs the phenomenon of water blockoff 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 anti-wear performance, it is slower to bore penetration rate.
The content of the invention
The purpose of the present invention is overcome the deficiencies in the prior art, and it is compound to provide a kind of diamond for being beneficial to draining during drilling
Piece coring bit, it is smaller that it solves existing diamond compact coring bit drain chamber size, is unfavorable for asking for draining
Topic, also solve the existing diamond compact coring bit drilling slow problem of chi.
The technical scheme is that：The diamond compact coring bit of draining during beneficial to drilling, including steel body and cut
Cut tooth；Steel body is in socket type, and its one end is the first end being connected with drilling equipment, and the other end is that cutting tooth is connected
Two ends；
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 includes a cutting tooth
A and at least one cutting tooth B, cutting tooth A are fixed on the end face at the second end of steel body, and cutting tooth B is fixed in the second of steel body
On the lateral wall at end, and with cutting tooth A in the axial direction close to；
Steel body is provided with drain chamber in the region between adjacent cutting tooth A.
Further technical scheme is the present invention：Each cutting tooth A front end is relative with adjacent cutting tooth A rear end；Institute
State front end for cutting tooth A close to one end of grinding surface, the rear end is the other ends of the cutting tooth A away from grinding surface；Each cutting
Tooth B front end is relative with adjacent cutting tooth B rear end；The front end is that cutting tooth B is close to one end of grinding surface, the rear end
The other ends of the cutting tooth B away from grinding surface.
Further technical scheme is the present invention：Cutting tooth has three groups, is put down vertically comprising two in one group of cutting tooth
The cutting tooth B of row arrangement, cutting tooth B grinding surface are provided with transversal crack.
Technical scheme of the invention further is：Drain chamber semicircular in shape.
The present invention has the following advantages that compared with prior art：
1st, drill bit abrasion resistance is good, takes during work stratum core convenient, 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 is smaller, and penetration rate greatly improves.
3rd, drill bit outer fractionlet is the leftover pieces of full wafer, recycling, cost reduction, it is competing to drastically increase market
Strive power.
Below in conjunction with figure, the invention will be further described with embodiment.
