Description

Technical Field

[0001] The invention relates to the technical field of geological exploration, in particular to a drilling sampling device for mining geological exploration. Background Art

[0002] In the field of mineral resource exploration and development, geological exploration is a vital link. It aims to reveal key information such as geological structure, rock type, mineral distribution, etc. below the earth's surface through scientific methods and technical means, and provide a scientific basis for the rational development and utilization of mineral resources. Among them, drilling sampling is the core link of geological exploration, and its technical level and advanced equipment are directly related to the accuracy and reliability of exploration results;

[0003] The Chinese announcement number is: CN114624053B, which discloses a mining geological exploration drilling sampling device, including an outer cylinder assembly, a drill bit and an inner cylinder assembly. The inner cylinder assembly does not rotate with the outer cylinder assembly. The bottom of the inner cylinder assembly is connected to a pull cylinder, and the interior of the pull cylinder is provided with a positioning cylinder. The positioning cylinder has multiple groups of grinding parts arranged along the axial direction. In the mining geological exploration drilling sampling device, the grinding parts can be drilled into the rock column when the outer cylinder assembly rotates, and the texture is soft and the drilling depth is deep. When the positioning cylinder is lifted with the pull cylinder, it can automatically locate the harder part of the rock column and cut off the rock column from the harder part. The harder rock column blocks the lower part of the inner cylinder assembly, which can avoid the scattering and sliding of the soft part, which is conducive to keeping the soil layer information intact. Secondly, the remaining core in the well is clamped and protected by the guide cylinder, and is completely retained in the upper part of the rock column during the next coring, so as to keep the soil layer information intact.

[0004] Although the above patent uses grinding parts, guide cylinders and other components to automatically locate the harder parts of the rock column, and seals the inner cylinder through the rock column to prevent the sample from scattering and ensure the integrity of the soil layer, considering the different distribution of rock layers in the mine, the components contained in the sampled cores will also be different. In some specific cases, when the integrity of the sampled rock soil needs to be ensured, the sealing of the sample needs to be ensured to prevent the detection data from being affected by some moisture or air;

[0039] like Figure 7-Figure 8 As shown, the sealing assembly 3 includes a sliding plate 31, which is slidably connected to the outer wall of the storage chamber 1. The sliding plate 31 is rotatably connected to a No. 1 connecting rod 32 at both ends of the side away from the storage chamber 1.

[0040] It can be seen from this that when it is necessary to sample the mine core, Figure 2-Figure 5As shown, after the staff places the bracket 11 at the designated sampling position, the entire storage chamber 1 is placed inside the bracket 11 for stabilization, and then stabilized by the limit bar 15. First, the motor 22 at the top of the adjustment chamber 2 drives the rotating rod 23 and the drill rod 24 to rotate together. At this time, the adjustment chamber 2 slides downward under the drive of the driving column 14, and drives the drill rod 24 to move downward. The drill rod 24 is used for sampling. At this time, if the depth of the sampling core touches a harder rock, it is necessary to adjust the position of the drill rod 24 by a smaller amplitude.

[0041] Embodiment 2

[0042] Different from the first embodiment, when the core in the storage chamber 1 needs to be sealed and stored, Figure 7-Figure 8 As shown, after sampling in the regulating chamber 2, the driving column 14 drives the regulating chamber 2 and the sliding frame 21 to slide upward, and in the process of the regulating chamber 2 moving upward, the sliding frame 21 will drive the push-pull rod 34 to pull inward and upward, and make the sealing covers 13 on both sides slide inward, at this time, the No. 1 connecting rod 32 and the No. 2 connecting rod 33 are affected by the tension, and the No. 1 connecting rod 32 and the No. 2 connecting rod 33 are contracted inwardly to each other, and drive the sealing cover 13 to contract toward the bottom of the preservation chamber 1, and finally the sealing covers 13 on both sides are merged and sealed. Similarly, when the core needs to be taken out again, the driving column 14 drives the regulating chamber 2 and the sliding frame 21 to slide downward a short distance again, and then the drill rod 24 pops out, and the staff takes out the core sample for testing. This can ensure that the core can be sealed during the inspection process, thereby ensuring the integrity of the core inspection.
