Hydraulic power head drilling rig is a type of rotary drilling rig. It is driven by a hydraulic motor through a reducer, and uses a power head that moves up and down along the tower instead of the turntable and faucet on the rotary drill rig to drive the drill pipe and drill bit to rotate and cut the rock formation. Large-diameter water wells can be drilled with large drill bits with a diameter of up to 1 meter. It is characterized by fast drilling speed, easy loading and unloading of drilling tools and easy running of well pipes. There is no need to lift the drilling tools when extending the drill pipe, and there is no need for winches, lifting pulleys, etc. A series of components such as turntables, faucets, and kelly rods. Down-the-hole vibratory rotary drilling rig is a rotary drilling rig that combines vibration and rotary motion to drill into rock formations. Drilling tools are composed of drill bits, vibrators, shock absorbers and guide tubes (Figure 3). The excitation force generated by the vibrator causes the entire drilling tool to perform a conical pendulum motion. The drill bit is set on the outside of the vibrator shell through a friction ring. On the one hand, it vibrates horizontally with the vibrator with a frequency of about 1000 rpm and an amplitude of about 9 mm; on the other hand, it vibrates around the axis of the vibrator at 3 to 12 rpm. The low-speed rotating motion is used to break the rock formation, while the drill pipe does not rotate, and the vibration absorber is used to prevent vibration from being transmitted to the drill pipe. The compressed air reverse circulation method is used to clean the well, so that the cuttings are discharged out of the well through the conduit located in the center of the vibrator and the inner cavity of the drill pipe. This kind of drilling rig has simple structure and high drilling efficiency. The diameter of the wellbore is about 600 mm, and the drilling depth can reach 150 meters.
