Problems solved by technology

[0002] With the continuous improvement of coal mining technology and the gradual enhancement of people's awareness of coal mine resource conservation, high-cost, time-consuming, labor-intensive, and low-efficiency mining methods have seriously restricted the mining level. The method is obviously unable to meet the basic mining needs. A low-cost, safe and efficient coal mining method has become an inevitable trend in the coal mining industry. PDC drill bits and TBM hobs are the most basic tools for coal mining, and their performance seriously restricts mining efficiency. and mining level, while the existing PDC bit and TBM hob are mostly set separately, most of them have complex structure, poor impact performance, low work efficiency, long operation switching time between PDC bit and TBM hob, and low coal mining efficiency
