Impact drilling rigs break rock layers into holes through the impact effect. This type of drilling rig was already used in ancient China, using manpower and bamboo bow elasticity to make the conical drill bit impact the formation. Modern impact drills, on the other hand, use more advanced power systems and impact mechanisms. The composite rotary drilling rig combines the characteristics of rotary and impact drilling rigs, allowing for flexible selection of suitable drilling methods under different geological conditions.

A water well drilling rig is a mechanical equipment specifically used for drilling water wells and completing operations such as lowering pipes and washing wells. It is mainly composed of power equipment, drill bits, drill rods, drill frames, etc., and has the characteristics of large drilling depth, large drilling diameter, and fast drilling speed. Water well drilling machines are usually divided into three categories: rotary rotary machines, impact drilling machines, and composite rotary machines.
