Problems solved by technology

[0003] In the existing drilling technology, the long drill bit is driven from the ground to drill into the ground, so that the sample enters the drill bit from the bottom of the drill bit to sample. Depth sampling requires multiple trips, which is inefficient and has a single function. Multiple equipments are required for one exploration

Abstract

The invention discloses a multifunctional efficient drilling device for geological survey. The device comprises a detection assembly, a derrick and a sliding mechanism, wherein the derrick is rotatably mounted on the base through an adjusting mechanism, the sliding mechanism can move along the derrick through a motor in a gear and rack driving mode, the sliding mechanism is fixedly connected withthe upper end of the drilling rod, a detection assembly is fixed to the bottom of the drilling rod, and the detection assembly can collect samples with different depths from the side face. Compared with the prior art, the multifunctional efficient drilling device is short in transmission distance, small in torsion loss and accurate in sample scraping position, the samples are prevented from leaking in the drill bit taking-back process, and the samples of different depths can be taken through one-time drilling.

Description

technical field [0001] The invention relates to the technical field of a drilling device, in particular to a multifunctional high-efficiency drilling device for geological survey. Background technique [0002] Geological prospecting is the investigation and research activity of conducting geological exploration and detection through various means and methods, determining the appropriate bearing layer, determining the foundation type and calculating the foundation parameters according to the foundation bearing capacity of the bearing layer. It is the discovery of mineral deposits with industrial significance in the general survey of mineral resources. In order to ascertain the quality and quantity of mineral products, as well as the technical conditions for mining and utilization, provide mineral reserves and geological data required for mine construction design, and analyze rocks and strata in a certain area. Conduct investigation and research work on geological conditions s...
