Description
Technical field
The utility model relates to for exploiting drill bit field, colliery, is specially a kind of diamond compact coring bit.
Background technology
In the process of geological prospecting, coal mining, water conservancy and hydropower, road and rail construction, tooth mainly plane structure brill tooth or laciniation brill tooth is bored in the work of current drill bit.But in rock hard especially, in order to understand the geological condition on stratum, need rock drilling coring and sampling, plane structure bores teeth drill bit can there is skidding and drilling depth problem slowly because contact area is larger, in order to solve the problem, generally can use jagged drill bit, but because jagged drill bit is in work progress, be subject to lateral pressure, the impact of the material factors such as depth of groove, sawtooth each several part is stressed excessive, there is bit wear and bore tooth by the phenomenon interrupted, thus shorten the application life of drill bit, bit change-over number of times is increased, cause the waste of time and resource, and bring potential safety hazard to staff.
Utility model content
The technical problem that the utility model solves is to provide a kind of novel core bit structure, solves the problem proposed in above-mentioned background technology, is specially a kind of diamond compact coring bit.
A kind of diamond compact coring bit, comprising: drill body, ducted body, drill body outer wall, cutting edge, alloy blade, described drill body is provided with ducted body, and drill body outer wall is polycrystalline diamond material, and drill body outer wall upper end is provided with cutting edge.
Described cutting edge discharges the two-layer alloy blade be arranged above and below in a step-wise manner, be looped around drill body upper end between cutting edge according to uniform distances with circular configuration, every layer of alloy blade top is smooth arcuate structure.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, be the two-layer cutting edge core bit of hollow, two-layer alloy cutting edge can increase the sharp keen of drill bit, improve the stock-removing efficiency of drill bit, reduce and change number of times, improve the application life of drill bit, be convenient to popularize.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in Figure 1, a kind of diamond compact coring bit, comprise: drill body 1, ducted body 2, drill body outer wall 3, cutting edge 4, alloy blade 5, drill body 1 is provided with ducted body 2, ducted body 2 is used for collecting core drilling sample, drill body outer wall 3 is polycrystalline diamond material, increase the soundness of drill bit, drill body outer wall 3 upper end is provided with cutting edge 4, cutting edge 4 discharges the two-layer alloy blade 5 be arranged above and below in a step-wise manner, increase the sharp keen of drill bit, improve the stock-removing efficiency of drill bit, every layer of alloy blade 5 top is smooth arcuate structure, increase the stability of drill bit, drill body 1 upper end is looped around according to uniform distances with circular configuration between cutting edge 4.
Drill bit of the present utility model is ducted body drill bit, is provided with two-layer alloy blade, in use, add the taxes and profits of drill bit, improve stock-removing efficiency, the structure of drill bit is polycrystalline diamond material, add the abrasion resistance using drill bit, reduce and change number of times, improve application life.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
