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.
Refer to Fig. 1, this utility model embodiment provide jet drill rig drill through mechanism, including drilling rod and the drill bit being arranged on drilling rod one end. Above-mentioned drilling rod includes outer drilling rod and is arranged on the interior drilling rod within outer drilling rod, and forms the cavity bypassed air through between the two, to transport air while transporting serosity.Concrete, outer drilling rod includes first coupling the 1, second coupling 2 and the male rod 3 being arranged between the first coupling 1 and the second coupling 2; Interior drilling rod includes first nipple the 4, second nipple 5 and is arranged on the core pipe 6 between the first nipple 4 and the second nipple 5, and first nipple 4 be provided with, with on the second nipple 5, the through hole that the mesopore with core pipe 6 connects, to transport serosity, when namely transporting, serosity transports by the middle of interior drilling rod, and air is transported by the cavity between interior drilling rod and outer drilling rod. Air and serosity after by drilling rod, can enter drill bit and spray from drill bit, and during ejection, it is farther that serosity can spray under the effect of air, thus improve the effect of serosity injection.
Certainly, the drill bit coordinated with above-mentioned drilling rod is preferably two-tube churning drill bit, between nipple and the coupling of this two-tube churning drill bit, there is the cavity for bypassing air through, this cavity connects with cavity, and be provided with the blind hole making serosity pass through connected with through hole on nipple, so that air and serosity pass through.
Consider interior drilling rod and the relative stability of outer drilling rod, male rod 3 and core pipe 6 are fixedly installed. Concrete, back-up ring 7 is set between male rod 3 and core pipe 6, male rod 3 is welded and fixed by this back-up ring 7 with core pipe 6, it is understandable that, back-up ring 7 needs arrange the perforate bypassed air through, while avoiding the relative male rod 3 of core pipe 6 to slide, it is ensured that air can transport smoothly.
For fixing between each parts of outer drilling rod, and fixing between each parts of interior drilling rod, it is preferred that elect the form removably connected as, to facilitate the dismounting to drilling rod, maintenance and replacing. Concrete, in the embodiment of the present application, male rod 3 and the first coupling 1 and the second coupling 2 are each through threadeding, and core pipe 6 and the first nipple 4 and the second nipple 5 are each through threadeding. Certainly, the fixed form between each parts can be various, it is not limited to threaded. Additionally, for the replacing facilitating joint, straight joint 8 also can be arranged between joint and core pipe 6, it is preferred that the two ends of this straight joint 8 are provided with screw thread, and are connected with core pipe 6 and joint screw thread respectively. Concrete, when arranging straight joint 8, can select to arrange according to actually used situation, can arrange between Partial joints and core pipe 6.
What this utility model embodiment provided drills through mechanism, and its drilling rod includes outer drilling rod and interior drilling rod, and has the cavity passed through for air between the two, and in use, air passes through in cavity, and flows to drill bit; Serosity can pass through from the first nipple 4 and the through hole of the second nipple 5 and the mesopore of core pipe 6 and flow to drill bit, sprays from drill bit. This drills through the drilling rod in mechanism when serosity is transported, air is transported to bit part simultaneously, serosity is mixed with air when ejection, thus spraying under the effect of air, what make that serosity sprays is farther, and then improve the effect that serosity sprays, and improve the work efficiency drilling through mechanism.
Mechanism is drilled through based on what above-described embodiment provided, this utility model embodiment also provides for a kind of twist bit, including rig body and drill through mechanism, and drilling through the drilling rod that mechanism includes being arranged on rig body and the drill bit being arranged on drilling rod, this drills through mechanism and above-mentioned drills through mechanism. The structure of the remainder of this twist bit refers to prior art, repeats no more herein.Above-mentioned drilling through mechanism owing to this twist bit has, therefore to a certain extent, this twist bit also improves the effect of serosity injection, and improves the work efficiency drilling through mechanism.
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.
