[0014] Furthermore, the positioning wedge block engages with the positioning wedge groove;

[0015] The above technical solution enables the first connecting seat and the second connecting seat to be fixed and limited when they are connected together.

[0016] Furthermore, the limiting groove is located at the center of the upper surface of the rod.

[0017] The above technical solution can absorb and guide the heat generated by the shaft.

[0018] Furthermore, a heat dissipation groove is provided at the center of the upper surface of the limiting rod;

[0019] The above technical solution guides and dissipates the heat generated by the shaft by setting up heat dissipation channels.

[0020] Furthermore, a threaded groove is provided at the upper end of the inner wall of the limiting groove, and a positioning screw block is threadedly fitted on the inner wall of the threaded groove.

[0021] The above technical solution enables users to push the position of the limiting rod in the limiting groove by rotating the positioning screw block.

[0022] Furthermore, a through hole is provided at the center of the inner bottom surface of the positioning screw block;

[0023] The above technical solution allows heat to circulate between the shafts by setting through holes.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] One embodiment provided by this utility model:

[0039] Reference Figure 1 , 2 5. A high-strength drill rod for mining, comprising a rod body 1, a first connecting mechanism 2 provided on the upper surface of the rod body 1, the first connecting mechanism 2 including a first connecting seat 201, a threaded connecting block 202 fixedly connected to the upper surface of the first connecting seat 201, a positioning inclined groove 203 provided on the inner wall of the threaded connecting block 202, a second connecting mechanism 3 provided on the lower surface of the rod body 1, the second connecting mechanism 3 including a second connecting seat 301, a threaded connecting groove 302 provided on the lower surface of the second connecting seat 301, and a plurality of positioning inclined blocks 303 fixedly connected to the middle of the inner top surface of the threaded connecting groove 302;

[0040] The rod body 1 is equipped with a locking mechanism 4, which includes a limiting groove 401. A limiting rod 402 is slidably connected to the inner wall of the limiting groove 401. A pressing block 404 is fixedly connected to the lower surface of the limiting rod 402. The structure of this mining drill rod is simple, and the user can quickly install and connect the drill rods. This not only improves the convenience of operating the mining drill rod, but also reduces the possibility of damage to the mining drill rod, thereby improving the convenience of maintenance and repair of the mining drill rod.

[0041] Reference Figure 1 , 35. The first connecting seat 201 is fixedly connected to the upper end of the outer wall of the rod body 1, and the second connecting seat 301 is fixedly connected to the lower end of the outer wall of the rod body 1. By setting the first connecting seat 201 and the second connecting seat 301, the rod body 1 can be connected and installed. The threaded connecting block 202 and the threaded connecting groove 302 are threadedly engaged, so that the first connecting seat 201 and the second connecting seat 301 can be initially connected and fixed. The positioning wedge block 303 and the positioning wedge groove 203 are engaged, so that the first connecting seat 201 and the second connecting seat 301 can be fixed and limited when connected together. The limiting groove 401 is opened on the upper surface of the rod body 1. At the center, the heat generated by the rod body 1 can be absorbed and guided. A heat dissipation groove 403 is provided at the center of the upper surface of the limiting rod 402. The heat generated by the rod body 1 is guided and dissipated by the heat dissipation groove 403. A threaded groove 405 is provided at the upper end of the inner wall of the limiting groove 401. A positioning screw block 406 is threadedly fitted on the inner wall of the threaded groove 405. The user can push the limiting rod 402 in the limiting groove 401 by rotating the positioning screw block 406. A through hole 407 is provided at the center of the bottom surface of the positioning screw block 406. The heat between the rod bodies 1 can be circulated by the through hole 407.

[0042] Working principle: First, the rod bodies 1 are connected and fixed together by the first connecting mechanism 2 and the second connecting mechanism 3. Through the threaded engagement between the threaded connecting block 202 and the threaded connecting groove 302, the first connecting seat 201 and the second connecting seat 301 are tightly fitted together. Then, the positioning screw block 406 is rotated to apply pressure to the limiting rod 402, causing the extrusion block 404 to push against the positioning inclined block 303. This causes the lower part of the positioning inclined block 303 to expand outward and fit tightly against the positioning inclined groove 203. Under the oblique extrusion and positioning action of the positioning inclined block 303 and the positioning inclined groove 203, the first connecting seat 201 and the second connecting seat 301 apply pressure to each other, reducing the possibility of thread loosening caused by drill rod vibration. This results in the upper rod body 1 and the lower rod body 1 being tightly and firmly connected together. Under the mutual extrusion action, the positioning screw block 406 is positioned and clamped, reducing the possibility of movement that could cause the extrusion block 404 to loosen.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
