Abstract
The invention discloses a core-drilling type hard alloy drill bit for a polar ice rock interlayer. A TSP (Thermal Stability Polycrystalline Diamond) composite sheet cutting tool is arranged at the top end of a drill bit body, an ice core breaker is arranged at the lower end of the TSP composite sheet cutting tool, a clamping groove is formed on the inner cavity wall of the drill bit body at the lower part of the TSP composite sheet cutting tool, and a clamp spring is arranged in the clamping groove. A knife-clamping spring is connected to the outer side wall of the lower end of the TSP composite sheet cutting tool and is disposed outside the ice core breaker, and a baffle plate is arranged on the outer side wall of the drill bit body, where the ice core breaker and the knife-clamping spring are arranged. The core-drilling type hard alloy drill bit for the polar ice rock interlayer has the beneficial effects that the core-drilling type hard alloy drill bit can effectively drill a core in the polar ice rock interlayer, the drilling efficiency is improved and the polar core-drilling progress can be accelerated.
Description
Technical field
The present invention relates to a kind of carbide drill, particularly a kind of polar region aqualite interlayer is cored formula carbide drill.
Background technology
Current, core in the course of work at polar drilling, there is the ice sheet of several meters to tens meters, mixed zone, rock stratum, to the coring of this aqualite interlayer be continue to go deep into rock stratum core drilling work under polar ice one of key request.Common ice drill bit is sharper, when creeping into aqualite interlayer, large to bit wear, drilling effect is undesirable, and mode of coring is also inapplicable, and when general diamond bit creeps in this aqualite interlayer, because drill bit structure feature causes diamond surface not exposed, be difficult to creep into, when coring, jump ring easily skids, poor effect of coring.Analyze existing formula carbide drill of coring, formula of the coring carbide drill being applicable to polar region aqualite interlayer is very important for the polar drilling work of coring, but does not still have corresponding aqualite interlayer drill bit at present.
Summary of the invention
The object of the invention is to core in the course of work in order to solve at polar drilling, common ice auger or the problem that geology rock core drill creeps into difficulty in the aqualite interlayer of polar region, effect of coring is undesirable, the formula carbide drill and a kind of polar region aqualite interlayer provided is cored.
Aqualite interlayer formula carbide drill of coring in polar region provided by the invention is provided with TSP composite sheet cutting element on the top of drill body, the lower end of TSP composite sheet cutting element is provided with moral purity card and breaks device, the internal chamber wall of the bottom drill body of TSP composite sheet cutting element offers draw-in groove, in draw-in groove, is provided with jump ring.
The lower end outside wall of TSP composite sheet cutting element is connected with swaging clamp spring, and swaging clamp spring is located at moral purity card and breaks the outside of device, be provided with moral purity card break device and swaging clamp spring place drill body lateral wall on be provided with catch.
The lower end of jump ring is provided with partition.
TSP composite sheet cutting element single loop arrangement has six, and cutting angle α is 0-10 °, and positively biased edge basil β is 5 °.
Operating principle of the present invention:
Drill body TSP composite sheet cutting element in rotation process cuts aqualite interlayer, catch covers in the gap that moral purity card breaks between device and drill body, avoid the inflow of drilling fluid, drilling fluid is flowed by the tank in drill body and water hole, forms local reverse-circulation at drill bit place.When creeping into end, when upwards carrying drill body, break device and jump ring of the aqualite heart in drill body compressing moral purity card moves, and moral purity card breaks the swaging clamp of device to the extruding of moral purity direction, and jump ring shrinks simultaneously, and the aqualite heart is disconnected by card, thus obtains aqualite heart sample.
Beneficial effect of the present invention:
The invention provides a kind of polar region aqualite interlayer to core formula carbide drill, can effectively creep in the aqualite interlayer of polar region and core, improve drilling efficiency, accelerate polar drilling and to core the process of work.

Detailed description of the invention
Refer to shown in Fig. 1, Fig. 2 and Fig. 3:
Aqualite interlayer formula carbide drill of coring in polar region provided by the invention is provided with TSP composite sheet cutting element 2 on the top of drill body 1, the lower end of TSP composite sheet cutting element 2 is provided with moral purity card and breaks device 3, the internal chamber wall of the bottom drill body 1 of TSP composite sheet cutting element 2 offers draw-in groove 4, in draw-in groove 4, is provided with jump ring 5.
The lower end outside wall of TSP composite sheet cutting element 2 is connected with swaging clamp spring 6, and swaging clamp spring 6 is located at moral purity card and breaks the outside of device 3, be provided with moral purity card break device 3 and swaging clamp spring 6 place drill body 1 lateral wall on be provided with catch 7.
The lower end of jump ring 5 is provided with partition 8.
TSP composite sheet cutting element 2 single loop arrangement has six, and cutting angle α is 0-10 °, and positively biased edge basil β is 5 °.
Operating principle of the present invention:
Drill body 1 TSP composite sheet cutting element 2 pairs of aqualite interlayers in rotation process cut, catch 7 covers in the gap that moral purity card breaks between device 3 and drill body 1, avoid the inflow of drilling fluid, drilling fluid is flowed by the tank in drill body 1 and water hole, forms local reverse-circulation at drill bit place.When creeping into end, when upwards carrying drill body 1, break device 3 and jump ring 5 of the aqualite heart in drill body 1 compressing moral purity card moves, and moral purity card breaks the swaging clamp of device 3 to the extruding of moral purity direction, and jump ring 5 shrinks simultaneously, and the aqualite heart is disconnected by card, thus obtains aqualite heart sample.
