Abstract
The utility model discloses a triangular rotor drill pipe, aiming at solving the problems in the prior at that an auger stem poor in bending resistance is generally used for coal hole drilling and cannot be removed out after the coal hole is collapsed caused by drilling. The triangular rotor drill pipe, as shown in figure 1, is composed of a male joint (1) and a female joint (2), wherein the male joint is connected with a triangular drill pipe (3); the other end of the triangular drill pipe is connected with the female joint; and the triangular drill rod is connected with a group of rotor sheets (4). The triangular rotor drill pipe disclosed by the utility model is used for drilling mine.
Description
Technical field
The utility model relates to a kind of triangle rotor drilling rod
Background technology
Now beat the coal hole and all use auger stem, the counter-bending ability extreme difference of auger stem often collapses the coal hole drill, causes drilling rod to remove to come out.
Chinese patent CN201220015349.9 discloses a kind of auger stem, is made up of the body of rod, male joint, female joint, and the body of rod is auger stem, and the bending resistance driving force of auger stem is bad in the process of boring, and the hole of boring is subsided
Summary of the invention
The purpose of this utility model provides that a kind of to bore that caving in can not appear in the coal hole, drilling rod is withdrawn from be to be relatively easy to triangle rotor drilling rod.
Described purpose is achieved by the following scheme:
A kind of triangle rotor drilling rod, its composition comprises: male joint, female joint, described male joint connects the triangle drilling rod, and the described triangle drilling rod other end connects described female joint, and described triangle drilling rod connects one group of rotary blade.
Described triangle rotor drilling rod, described male joint is truncated cone-shaped, and the end of described male joint is circular arc, and the afterbody of described male joint has the connection boss.
Described triangle rotor drilling rod, described male joint, described female joint, described triangle drilling rod all have through hole.
The rear portion has the truncated cone-shaped hole in the described triangle rotor drilling rod, described female joint, and described truncated cone-shaped hole connects boss hole, described truncated cone-shaped hole other end connecting through hole, and described connecting through hole connects the through hole of described triangle drilling rod.
Described triangle rotor drilling rod, the diameter of the connection boss of described male joint is d, the diameter of the through hole of described male joint is f, the connection boss of described male joint is b to the distance of end, the boss hole diameter of described female joint is g, the external diameter of described female joint is h, the length in the truncated cone-shaped hole of the boss hole of described female joint and described female joint and be c.
The beneficial effects of the utility model are:
The triangle drilling rod that the utility model adopts counter-bending very competent bored and withdrawn from behind the hole smoothly, and the hole of boring is complete, can not cave in.
The position at the angle of the triangle drilling rod that the utility model adopts is circular arc, and the hole that gets out is very regular circle, the not phenomenon that can occur caving in.
The rotary blade that the utility model adopts can be scraped out with the powder that inner hole deposition forms sediment, and water is rushed out the powder that inner hole deposition forms sediment, and has improved the operating efficiency of rig.
