Description

It can drive the drill to drill underground to obtain physical geological data, including but not limited to cores, ore cores, cuttings, gas samples, liquid samples, etc., to explore the underground geology and mineral resources.

[0003] The multifunctional rock and soil geological drilling rig has a relatively high height, which is not convenient for transportation. Therefore, the existing multifunctional rock and soil geological drilling rig is generally installed on a mobile vehicle through a rotating device, and the rotation of the drilling rig is driven by a hydraulic cylinder. During transportation, the drilling rig is in an inclined or horizontal state, which is used to reduce the height of the drilling rig.
