Abstract

The invention relates to a diamond coated drill bit, and mainly relates to the technical field of drill bits for drilling. According to the diamond coated drill bit, when mine drilling operation is carried out, in the drilling process, a control module compares the detected actual temperature of the drill bit with the preset drilling temperature, compares the actual drilling amount of the drill bit with the preset minimum drilling amount and calculates the average vibration frequency of the drill bit within a period of time, if the temperature and the vibration frequency in the comparison result meet the requirements, the drilling quantity is larger than or equal to the preset minimum drilling quantity, and the actual rotating speed of the drill bit exceeds the preset maximum rotating speed, the rotating speed of the drill bit is controlled to be reduced through an adjusting control module, the drilling quantity is lower than the preset minimum drilling quantity, the actual rotating speed of the drill bit exceeds the preset maximum rotating speed, the control module judges that the drill bit needs to be replaced, the self-checking capacity of the drill bit is improved, and the drilling efficiency of the drill bit is improved.

Description

technical field [0001] The invention relates to the technical field of drill bits for drilling, in particular to diamond-coated drill bits. Background technique [0002] When mining, drilling is an important process. Since the structure of the underground rock formation is very complex during drilling, it is necessary to select different hardness drill bits for drilling according to the structure of different rock formations. The existing rock formations with higher hardness basically use Diamond coating is used to improve the hardness of the drill bit, but the formation of the drill hole has many influencing factors. Therefore, the quality of a drill hole requires high requirements for the size of the drill bit and the film thickness of the diamond coating. In the prior art, for With the complex rock structure, when drilling, only the drill bit with a relatively single hardness is selected for drilling after the preliminary inspection. During the drilling process, due to th...
