Description

Technical Field

[0001] The utility model relates to the technical field of geological drilling, in particular to a foldable drilling device for geological exploration. Background Art

[0002] Geological drilling uses drilling equipment to obtain underground rock samples. By analyzing the parameters of rock samples, it can provide data support for ore evaluation, mineral resources, mineral distribution, and geological composition. Geological drilling has formed a systematic independent discipline and is used in industries such as industry, mining, and infrastructure. At present, there are three methods of geological drilling, including: impact drilling, which uses the weight of the drill bit and mechanical impact to drill into soft soil layers, and is mostly used for exploration; rotary drilling, which is a method of grinding the cylindrical drill bit under axial pressure, and is suitable for rocks with drillability grades below 7; impact-rotary drilling, a drilling method that combines impact and rotation, greatly improves drilling efficiency.

[0003] The authorization announcement number is CN212479090 U, which discloses a drilling device for geological exploration, including a drilling base, wherein the four corners of the inner wall of the drilling base are hingedly provided with a first connecting rod, one end of the four first connecting rods is rotatably connected to one end of the second connecting rod, and the other ends of the four second connecting rods are rotatably connected to the two ends on both sides of the drilling chassis, and a threaded column is rotatably provided at the top of the inner wall of the drilling base. The utility model provides a drilling device for geological exploration. By installing a connecting rod group at the four corners inside the drilling base and installing a lead screw in the middle of the inner wall of the drilling base, on the one hand, the drilling chassis threadedly connected to the lead screw is moved up and down, driving the universal wheel to extend and retract, thereby supporting the entire drilling device, making it convenient to move the entire drilling device. On the other hand, the universal wheel is retracted, so that the drilling base is fixedly set on the ground and will not move during drilling, which is convenient for the drilling head to drill downward for sampling, thereby achieving a fixed sampling effect.
