Description

Mining equipment drilling equipment

Technical Field

The utility model relates to a be used for rotary drill field, concretely relates to mining equipment drilling equipment.

Background

The mining industry is an important basic industry related to the national economic life and energy safety, particularly the coal industry, although in recent years, China has been adjusting energy structures and reducing the proportion of coal in energy consumption. However, the proportion of coal in the primary energy structure is still kept above 60%, and the coal will not swing as the main energy of China in a long period in the future. Because the geological conditions of the coal mine in China are complicated and changeable, the overall technical level of coal production is low, besides the complicated geological conditions of the coal mine in China, the mining difficulty is high, the gap between the coal mining mechanization degree and the advanced coal producing country is large, the mining technology and the equipment level are far behind other advanced coal producing countries, and the following problems can occur in the use process of the existing rotary drill:

1. due to the fact that the road surface of the mine is uneven, the phenomenon that the drill hole is inclined occurs in the drilling process, and further later-stage mining operation is affected;

2. when the drill bit is used for drilling, high-strength pressure is formed between the drill bit and the bottom of a drilled well easily, so that the drill bit idles and is not used for cutting ores, and the drilling efficiency is finally influenced;

for this reason, there is an urgent need to solve the existing problems.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, an object of the utility model is to provide a mining equipment drilling equipment reaches the purpose of effective stable drilling.

In order to achieve the purpose, the utility model relates to a drilling device for mining equipment, which comprises a base, a plurality of fixing components, a fixing rod, a sleeve rod and a drill bit, wherein the fixing rod is fixedly arranged on the side surface of the base, the drill bit is fixedly connected with the fixing rod through the sleeve rod, a cavity is arranged inside the drill bit, the cavity is mutually communicated with the inside of the sleeve rod, and the drill bit and the sleeve rod are provided with through air holes;

the fixed assembly comprises a screw and a negative pressure sucker, and the negative pressure sucker is in threaded connection with the bottom of the base through the screw.

Further, the number of the fixing components is at least three.

Furthermore, a negative weight block is fixedly arranged on the base.

Furthermore, the bottom of base is fixed and is equipped with the universal wheel.

Furthermore, the edge of base is fixed and is equipped with the guardrail.

Compared with the prior art, the utility model, its beneficial effect is:

the negative pressure sucker can adjust the height of the base through the screw rods, the base can be adjusted through the screw rods, the levelness of the base can be finally adjusted, severe vibration can be generated during drilling, the negative pressure sucker is adopted to suck the ground, and compared with the traditional method that the negative pressure sucker is directly driven into the ground through bolts, the levelness of the base cannot be changed due to vibration, the screw rods are in threaded connection with the base, the effect of preventing vibration to influence the levelness of the base is achieved, and the principle of a jack is applied;

when the drill bit drills, high-strength air pressure formed by the drilled hole and the bottom of the drilled hole flows into the outside through the air holes, and finally the drill bit can be always abutted against the bottom of the drilled hole, so that idling is prevented from occurring, and further the working efficiency is influenced;

in conclusion, the device can achieve the purpose of effectively and stably drilling.
