Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1 to Fig. 2, the two-tube churning drill bit that this utility model embodiment provides, it has nipple 1, coupling 2, blast cap 3, nozzle assembly 4 and fin 6.Being provided with blind hole 11 on above-mentioned nipple 1, serosity is entered in nipple 1 by this blind hole 11, and the side of nipple 1 is provided with nozzle assembly 4, and for being sprayed by serosity, concrete, serosity passage 41 on nozzle assembly 4 sprays. The outside of nipple 1, it is provided with coupling 2, namely this coupling 2 is enclosed within the outside of nipple 1, and form cavity 5 between the two, in addition, position corresponding with nozzle assembly 4 in coupling 2 is provided with installing hole, and equipped with being used for the blast cap 3 of air ejection, and this blast cap 3 is equipped with nozzle assembly 4. Air flows in cavity 5, and can on blast cap 3 perforate 31 place ejection, thus mixing with serosity, after mixing, under the effect of air serosity can spray farther, the gunite effect of shower nozzle is better. Preferably, above-mentioned perforate 31 is coaxially disposed with passage 41, and is positioned at the periphery of serosity at nozzle air, to ensure to be sufficiently mixed. Fin 6 is arranged on one end of coupling 2, concrete, is located remotely from the side of blind hole 11 opening, and for stratum is drilled through, fin herein can be preferably Q235 fin.
In the use procedure of two-tube churning drill bit, it is to be ensured that the relative stability between nipple 1 and coupling 2, now, both can be fixedly installed, it is preferred that nipple 1 is welded and fixed near one end of fin 6 with coupling 2 near one end of fin 6. Certainly, being fixedly installed herein is not limited to welding, and under being capable of this precursor being fixedly installed, all the other forms are also feasible.
In one embodiment of the application, the internal diameter of passage 41 is set to change, and interior tapers into the one end away from blind hole 11 near one end of blind hole 11 without leave, and when internal diameter is reduced to target value, the inner diameter values of passage 41 tends to be steady, and no longer changes. Due to the size being smaller in size than porch of nozzle in this passage 41, therefore, the serosity flow velocity when ejection can be relatively big, so that serosity ejection is farther, and then improves gunite effect and the work efficiency of drill bit.
Additionally, yielding groove also can be offered in coupling 2, to facilitate blast cap 3 to dismount. In one preferred version of the application, the periphery of blast cap 3 is provided with external screw thread, and blast cap 3 passes through threaded engagement with coupling 2, thus facilitating the dismounting to blast cap 3, and is easy to the maintenance to blast cap 3 and replacing. In another preferred version, nozzle assembly 4 is provided with external screw thread, and by threaded engagement between nozzle assembly 4 and nipple 1, thus facilitating the dismounting of nozzle assembly 4, it is carried out, keeps in repair or changes. Certainly, blast cap 3 and nozzle assembly 4 are installed each through screw thread is also feasible, it is to be understood that is not limited to screw thread and installs, it is also possible to being be bolted or the form of clamping, concrete installation form can select according to actual production demand.
The two-tube churning drill bit that this utility model embodiment provides, nipple 1 is provided with blind hole 11, and nozzle assembly 4 is arranged on nipple 1, and serosity, after entering blind hole 11, can spray by the passage 41 on nozzle assembly 4 under pressure. Additionally, have cavity 5 between nipple 1 and coupling 2, air can flow in this cavity 5, and owing to being provided with blast cap 3 in coupling 2, blast cap 3 is provided for the perforate 31 that air passes through, and therefore, air can spray from perforate 31. Above-mentioned blast cap 3 coordinates with nozzle assembly 4, at serosity while passage 41 sprays, air sprays from perforate 31, so that air mixes with serosity, owing to air has certain pressure, therefore after mixing, serosity can spray farther under the effect of air, thus improve the gunite effect of drill bit, and then improve work efficiency.
Based on the two-tube churning drill bit that above-described embodiment provides, this utility model embodiment also provides for a kind of twist bit, and including rig body, the drilling rod being arranged on rig body and be arranged on the drill bit on drilling rod, and this drill bit is above-mentioned two-tube churning drill bit. The concrete structure of the remainder of this twist bit refers to prior art, repeats no more herein. Owing to this twist bit has above-mentioned two-tube churning drill bit, therefore to a certain extent, this twist bit also has higher gunite effect and work efficiency.
Adopting the form gone forward one by one to be described in this specification between each embodiment, what each embodiment stressed is all the difference with other embodiments, the similar portion between each embodiment mutually referring to.
Described above to the disclosed embodiments, makes those skilled in the art be capable of or uses this utility model. The multiple amendment of these embodiments be will be apparent from for a person skilled in the art, and generic principles defined herein when without departing from spirit or scope of the present utility model, can realize in other embodiments.
