Description
Technical field
The utility model is related to bit technique fields more particularly to a kind of circular cone to crush drill bit.
Background technology
Currently, drill bit type on the market is various, different shapes is marked off according to different functions, is used for crushing function
Drill bit generally use pyramid type drill bit, the diameter of tip to the rear of drill bit gradually increases, but main function is tip, after
Edge point is unable to give full play effect, little to the effect of reaming, and in drilling process, the discharge of clast is ineffective,
The phenomenon that being susceptible to plug-hole, it is relatively low so as to cause working efficiency.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of circular cone crushing drill bit, fully profit
It is cut with each position of drill bit, drilling efficiency is high, and clast can be discharged in time.
Technical solution is used by the utility model solves its technical problem：
A kind of circular cone crushing drill bit, it is described from top to bottom successively including connecting rod, round platform crushing knife stage body and subland drill
Subland drill bottom has positioning apex point, and the side of the round platform crushing knife stage body offers a plurality of cutting slot, the round platform powder
Broken knife stage body is located at cutting slot one side edge and is additionally provided with the cutting tip for extending to cutting slot opening.
As an improvement of the above technical solution, a plurality of helicla flute is offered on the outside of the subland drill.
As an improvement of the above technical solution, the cutting slot and helicla flute correspond and the lower ending opening of cutting slot with
The upper end opening of helicla flute is connected.
As an improvement of the above technical solution, the cutting slot from top to bottom runs through the outside of round platform crushing knife stage body, institute
State the outside that helicla flute from top to bottom runs through subland drill.
As an improvement of the above technical solution, the groove depth of the cutting slot and helicla flute is from top to bottom gradually reduced.
As an improvement of the above technical solution, the cutting slot, helicla flute and cutting tip are both provided with four groups.
As an improvement of the above technical solution, the cutting tip is anchored on the outer of round platform crushing knife stage body by screw
Side.
The beneficial effects of the utility model have：
This drill bit makes full use of each position to be cut, and round platform crushing knife platform is added between connecting rod and subland drill
The side of body, round platform crushing knife stage body offers a plurality of cutting slot, facilitates timely chip removal, and cutting slot one side edge is additionally provided with
The cutting tip of cutting slot opening is extended to, cutting tip can cut hole wall, play a decisive role to the expansion of drilling, bore
Into very high with crush efficiency.
Description of the drawings
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail, wherein：
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the vertical view of Fig. 1；
Fig. 3 is the hidden line visible structure schematic diagram of round platform crushing knife stage body in the utility model embodiment.
Specific implementation mode
Referring to Fig. 1, a kind of circular cone of the utility model crushes drill bit, includes from top to bottom connecting rod 1, round platform crushing successively
There is positioning apex point 4, positioning apex point 4 to be used for centralized positioning trepanning for knife stage body 2 and subland drill 3,3 bottom of the subland drill,
It is directed at center hole to be drilled, connecting rod 1 connects driving source, such as gasoline engine.
With further reference to Fig. 2 and Fig. 3, the side of the round platform crushing knife stage body 2 offers a plurality of cutting slot 5, the circle
Platform crushing knife stage body 2 is located at 5 one side edge of cutting slot and is additionally provided with the cutting tip 6 for extending to 5 opening of cutting slot, the cutting
Blade 6 is anchored on the outside of round platform crushing knife stage body 2 by screw 8, and cutting tip 6 can cut hole wall, the expansion to drilling
It plays a decisive role, drilling and crush efficiency are very high.
Wherein, the outside of subland drill 3 offers a plurality of helicla flute 7, and cutting slot 5 is corresponded and cut with helicla flute 7
The lower ending opening of slot 5 is connected with the upper end opening of helicla flute 7 so that the clast in helicla flute 7 can successfully lead to cutting
In slot 5.
As shown in figure 3, the visual cutting slot 5 of dotted portion, screw 8 and cutting tip 6, specifically, cutting slot 5 by up to
Run through the outside of round platform crushing knife stage body 2 down, helicla flute 7 from top to bottom runs through the outside of subland drill 3, and clast is by cutting slot 5
Upper end opening is expelled directly out, in addition, the upper end and lower end of cutting tip 6 are concordant with the upper end of cutting slot 5 and lower end holding respectively.
Due to entire drill bit from top to bottom reduced diameter, the groove depth of cutting slot 5 and helicla flute 7 is from top to bottom gradually
Reduce, meets the needs of practical chip removal.In the present embodiment, the cutting slot 5, helicla flute 7 and cutting tip 6 are both provided with four groups
And it uniformly arranges.
The above, the only better embodiment of the utility model, but the utility model is not limited to above-mentioned reality
Example is applied, as long as it reaches the technique effect of the utility model with any same or similar means, should all belong to the utility model
Protection domain.
