Has good maneuverability, can move quickly with tires, adapts to various terrains, and is easy to transfer between different construction sites. The operation is mainly controlled by hydraulic pressure, which is simple and labor-saving, with high drilling efficiency. It can automatically adjust parameters according to geological conditions, and has complete safety protection devices to adapt to different drilling depths, diameters, and geological conditions.

Working principle:
Usually powered by a diesel engine or electric motor, the rotary table is driven by a transmission system to rotate, thereby rotating the drill rod and drill bit. At the same time, the hydraulic system pushes the drill rod to feed, and the drill bit cuts the formation to achieve drilling. During the drilling process, the mud pump injects mud or water into the drill pipe, carrying rock debris to the ground to complete slag discharge, while the winch is responsible for lifting and lowering equipment such as the drill pipe.

Scope of application: Widely used in geological survey exploration, road and high-rise building foundation exploration, etc. It can also be used for drilling water wells, including civil water wells, agricultural irrigation wells, geothermal air conditioning holes, etc., especially suitable for water intake projects in mountainous areas and rock formations.

The four-wheel tire water well drilling rig mainly drives the hydraulic system through the power system, and the hydraulic system controls the actions of various components to achieve drilling operations. The specific process is as follows:

• Drilling: The power system drives the turntable to rotate, and the turntable drives the drill bit to rotate through the drill rod. At the same time, the hydraulic system controls the oil cylinder to push the drill rod downwards, so that the drill bit cuts and breaks the formation, achieving the drilling function.
• Slag discharge: During the drilling process, a large amount of waste such as rock debris and soil will be generated. Inject mud or water into the drill rod through a mud pump, spray it out from the nozzle of the drill bit, and carry the rock debris to the ground to achieve the function of slag discharge.
• Lifting and lowering: When it is necessary to replace the drill bit, extend the drill rod, or complete the drilling operation, the lifting and lowering of the drill rod is controlled by a winch, and the drill rod is lifted out of or placed into the wellbore.
