Description

Double-end drill rod

Technical Field

The utility model relates to the technical field of drill rods, in particular to a double-head drill rod.

Background

More effective broken stone and rock can be more in the construction to the quartering hammer, and the drill rod is the machines and tools of roadway engineering connection drill bit and rock drilling, and the drill rod on the quartering hammer of current is various, and is different to broken thing, and the drill rod shape of design is also different, but exists to viscidity or the bigger ore crushing efficiency of softness low, and broken area is little, and crushing ability is low, the low scheduling problem of operating efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art, and provides a double-end drill rod which is easier to crush ores with larger viscosity or softness, increases the crushing area, increases the crushing capacity, has high crushing efficiency, improves the working efficiency and can effectively solve the problems in the background art.

In order to achieve the purpose, the utility model provides the following technical scheme: the double-head drill rod comprises a drill rod tail arranged at the tail of a drill body and a drill rod head arranged at the head of the drill body, wherein a mounting groove is formed in the side wall of the drill rod tail, a transition part is arranged at the tail end of the head of the drill body, the tail end of the transition part is connected with the drill rod head, the drill rod head is of a double-drill-bit structure and comprises a drill bit A and a drill bit B, and the drill bit A and the drill bit B are identical in structure.

Furthermore, the drill bit A and the drill bit B are both in a conical structure, and the center of the cross line of the head parts of the drill bit A and the drill bit B is superposed with the center line of the drill body.

Furthermore, the included angle between the center lines of the drill bit A and the drill bit B is 18-26 degrees.

Furthermore, the transition part is of a circular truncated cone-shaped structure with a large upper end outer diameter and a small lower end outer diameter, and the outer diameter of the top end of the transition part is matched with the outer diameter of the drill body.

Compared with the prior art, the utility model has the beneficial effects that: this double-end drill rod is favorable to letting the gaseous through-flow of drill rod head through two drill rod head structures, and the ore can be cut into to the drill rod front end like this, makes the drill rod more broken viscidity or the bigger ore of softness ratio more easily, increases broken area, increases crushing ability, and broken high-efficient improves the operating efficiency.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is an enlarged view of the head of the present invention.

In the figure: 1 drill body, 2 drill bit tails, 3 mounting grooves, 4 transition parts, 5 drill rod heads, 51 drill bits A and 52 drill bits B.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

Referring to fig. 1-2, the present invention provides a technical solution: a double-head drill rod comprises a drill rod tail 2 arranged at the tail of a drill body 1 and a drill rod head 5 arranged at the head of the drill body 1, wherein the side wall of the drill rod tail 2 is provided with an installation groove 3, the tail end of the head of the drill body 1 is provided with a transition part 4, the tail end of the transition part 4 is connected with the drill rod head 5, the drill rod head 5 is of a double-bit structure and comprises a drill rod A51 and a drill rod B52, the drill rod A51 and the drill rod B52 are identical in structure, and the double-bit structure is beneficial to enabling the gas at the drill rod head 5 to flow through, so that double-head ores can be cut into at the front end of the drill rod, the drill rod can more easily crush sticky ores or more soft ores, the crushing area is increased, the crushing capacity is increased, and the operation efficiency is improved.

Furthermore, the drill bit A51 and the drill bit B52 are both conical structures, the center of the intersection line of the drill bit A51 and the drill bit B52 is overlapped with the center line of the drill body 1, ores are crushed simultaneously through the drill bit A51 and the drill bit B52 during crushing, the crushing unit area is increased, and the ventilation effect is good during crushing and striking.

Furthermore, the included angle between the center lines of the drill bit A51 and the drill bit B52 is 18-26 degrees, so that the gas through flow of the drill rod head 5 is facilitated, and the ore crushing capacity is high.

Furthermore, the transition part 4 is in a circular truncated cone-shaped structure with a large upper end outer diameter and a small lower end outer diameter, and the outer diameter of the top end of the transition part 4 is matched with the outer diameter of the drill body 1.

When in use: when the drill rod head part 5 is used for crushing ores, the double-drill-bit structure is favorable for enabling the gas at the drill rod head part 5 to flow through, so that the front end of the drill rod can cut into the ores with double heads, the drill rod can crush the ores with high viscosity or larger loose and soft more easily, the crushing area is increased, the crushing capacity is increased, and the operation efficiency is improved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
