Specific embodiment
The following description and drawings fully show specific embodiments of the present invention, to enable those skilled in the art to
Practice them.Other embodiments may include structure, logic, it is electrical, process and other change.Embodiment
Only represent possible variation.Unless explicitly requested, otherwise individual components and functionality is optional, and the sequence operated can be with
Variation.The part of some embodiments and feature can be included in or replace part and the feature of other embodiments.This hair
The range of bright embodiment includes equivalent obtained by the entire scope of claims and all of claims
Object.
As shown in Fig. 3 to 6, in some illustrative embodiments, a kind of interior deslagging binary channels drilling rod is provided, comprising: outer
Pipe 1, inner tube 2, support helix band 3 and external spiral band 4.
The inside of outer tube 1 is arranged in inner tube 2, forms first passage 5 inside inner tube 2, medium 17 flows in first passage 5
It is dynamic.A cavity is formed between the outer surface of inner tube 2 and the inner surface of outer tube 1, as second channel 6, medium 17 carries material 18
It is flowed in second channel 6.Several support helix bands 3 being parallel to each other of setting, the side of support helix band 3 in second channel 6
Face is welded on the outer surface of inner tube 2, and another side is welded on the inner surface of outer tube 1, and outer tube 1 and inner tube 2 pass through support helix band 3
Be welded as a whole structure.One end of inner tube 2 is arranged extension tube 11, and the outer surface of extension tube 11 opens up external screw thread, inner tube 2 it is another
The inner surface at end opens up internal screw thread, i.e. binary channels drilling rod one end of the utility model is helicitic texture, and the other end is nut structure,
Convenient for being attached with other pipes.
External spiral band 4 is wrapped in the outer surface of outer tube, and external spiral band 4 is welded on the outer surface of outer tube 1, not only realizes and collapses
Hole deslagging, and drilling rod rigidity is improved, it is not easily broken.
Winding direction of the external spiral band 4 in the outer surface of outer tube 1, winding with support helix band 3 in the outer surface of inner tube 2
Direction is consistent, is not only convenient for deslagging, drilling, and Impact direction is consistent, further increases the intensity of drilling rod.
