Problems solved by technology
[0002] During the working process of the rotary drilling rig, the ideal state is to be able to monitor the vertical resistance and lateral resistance of the drill bit in real time to help the operator judge the geological conditions, but it is not convenient to install a pressure sensor on the drill bit, so in the prior art It mainly depends on the pressure gauge of the hydraulic system and the readings of the engine ECU, and is judged by the professionalism of the operator. Operators are required to be professional enough, which brings a very high burden to the enterprise
