It includes an oil tank, an actuator, a power source, a reversing valve group, a sensor group, a pressure adjustment oil circuit, and a controller. The sensor group monitors the impact pressure and propulsion pressure values ​​in the pressure adjustment oil circuit in real time. The impact pressure in the pressure adjustment oil circuit is dynamically adjusted using an impact force adjustment oil circuit formed by connecting a first pressure valve group and a reversing valve group. Similarly, the propulsion pressure in the pressure adjustment oil circuit is dynamically adjusted using a propulsion force adjustment oil circuit formed by connecting a second pressure valve group and a reversing valve group. This improves drilling efficiency while extending equipment life, solving the problem that current hydraulic systems cannot adjust the impact pressure during operation according to actual working conditions.
