Problems solved by technology

[0003] Traditional geological sampling equipment is usually bulky, and since geological sampling locations are mostly mountains and ravines, it is not easy to carry when working in the field; existing smaller volume geological testing sampling equipment usually has limited geological sampling depth and cannot achieve the expected results, mainly relying on manpower Sampling is time-consuming and labor-intensive; the existing geological sampling equipment can only sample horizontally or vertically, and cannot be flexible with changes in sampling geological conditions, which increases the difficulty of sampling
In addition, geological samples are easily blocked inside the drill bit during the sampling process, and it is necessary to manually knock the outer wall of the drill bit to drop the sample, which not only increases the labor intensity of the staff, but also may damage the integrity of the sample and reduce work efficiency

Embodiment 1

[0040] Figure 1-Figure 3 A schematic diagram of a multifunctional geological sampling device is given schematically. The device consists of a geological sampling system and an auxiliary system. Different systems are selected according to different terrain conditions and sampling requirements. If vertical sampling is required, the entire device can be directly applied without disassembly.

[0041] The geological sampling system includes a motor 3, and the motor 3 is surrounded by a metal casing, and control handles 1 are installed at the left and right ends of the metal casing, and a rubber sleeve 2 is wrapped around the control handle 1;

[0042] The motor 3 is fixedly arranged on the upper surface of the bearing plate 4, and the lower part of the bearing plate 4 is connected with the outer cylinder 5 of the sampling device;

[0043] A hole is provided at the center of the load-bearing plate 4;

[0044] A motor central shaft 7 is connected below the motor 3, and the motor c...

Embodiment 2

[0056] When geological sampling is carried out in the field, it cannot be guaranteed that the vertical operation is performed on the ground every time. The geological sampling system of the present invention can perform sampling on the rock wall. In the case of horizontal sampling, just remove the screw 11 of the present invention, separate the geological sampling system and the auxiliary system, and then use the screw 11 to fix the geological sampling system on the rock wall to be sampled. It should be noted that the high-pressure water tank 8 needs to be located directly above the sampling pipe 17 . The high-pressure nozzle 9 is also inclined downward, but the acute angle between the high-pressure nozzle 9 and the sampling pipe 17 is controlled at about 35 degrees.

[0057] The rest of the operations are similar to those in Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a multifunctional geological sampling device and a sampling method thereof.The multifunctional geological sampling device comprises a geological sampling system, a motor is fixedly arranged on the upper surface of a bearing plate, and the lower portion of the bearing plate is connected with an outer cylinder of the sampling device; a motor middle shaft penetrates through a hole in the center of the bearing plate, and the lower part is connected with a sampling pipe; the sampling pipe is of a structure in which a plurality of sections of sleeves are sequentially sleeved from inside to outside, a sampling tool bit is mounted at the lower end part of the section of sleeve at the innermost layer of the sampling pipe through threads, and a shooting device with a lighting function is mounted in the lower end part of the section of sleeve at the innermost layer of the sampling pipe and is used for detecting the information of a drilled rock stratum at present. When a sampling field is a flat ground and longitudinal sampling is needed, the geological sampling system and the auxiliary system are used at the same time; when transverse sampling needs to be carried out on the rock wall, only the geological sampling system needs to be fixed on the rock wall needing sampling. According to the invention, visual sampling can be realized, and the sampling uncertainty is reduced.

Description

technical field [0001] The invention relates to the technical field of mining machinery in geological mines, is suitable for geological detection and sampling, and more particularly relates to a multifunctional geological sampling device and a sampling method thereof. technical background [0002] Geological sampling refers to mining a certain quantity and quality of samples from the ground according to certain specifications and requirements, and through research and analysis to determine the rock origin, mineral quality, physical and chemical properties of ore and surrounding rocks, ore processing conditions, deposit mining technical conditions and Reserve calculation, etc. With the rapid development of science and technology, the global demand for mineral resources is increasing. However, geological sampling will be carried out before mineral mining, and the samples will be identified and analyzed before deciding on the technical plan for mining. [0003] Traditional geo...
