Description

Technical Field

[0001] This utility model relates to the technical field of soil sampling equipment, specifically to a geochemical soil sampling device for geological prospecting. Background Technology

[0002] In the field of geological prospecting, geochemical soil sampling is an important step in obtaining geological information and determining the distribution of mineral resources. Accurate and complete soil samples can provide a reliable basis for subsequent chemical analysis and mineral prediction. At present, most geochemical soil sampling devices widely used in the market adopt a sampling tube structure that can be separated into half. This design makes it easy to remove the soil sample after sampling for subsequent analysis and testing.

[0003] However, existing detachable sampling tubes have significant drawbacks in their fixing method. They are mainly secured to the two halves of the sampling tube with bolts. After sampling, the operator needs to completely remove the bolts from one half of the sampling tube to remove the soil sample. This separation method is prone to disturbing the soil in the remaining sampling tube during actual operation. On the one hand, the external force when removing the bolts may cause the soil to shift and loosen inside the sampling tube; on the other hand, directly removing one half of the sampling tube will disrupt the original soil accumulation, especially for some loosely structured or specific soil samples. Layered soil samples may exhibit disordered stratification and compromised integrity. If the stability and integrity of soil samples cannot be guaranteed, it will directly affect the accuracy of subsequent chemical analysis data, thereby interfering with the reliability of mineral resource exploration results and increasing errors and risks in prospecting. Therefore, existing geochemical soil sampling tubes, which use bolt fastening and have unreasonable separation methods, are no longer sufficient to meet the high-quality soil sample collection requirements of geological prospecting. There is an urgent need to develop a new soil sampling device to solve the problem of unreliable soil stability during the separation process of the sampling tube, and to improve the accuracy and effectiveness of soil sampling.

[0004] The above content is only used to help understand the technical solution of this utility model, and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned shortcomings and provide a geochemical soil sampling device for geological prospecting.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a geochemical soil sampling device for geological prospecting, comprising a sampling handle and a sampling cylinder, wherein the sampling handle is composed of a holding column and a connecting column, and the sampling cylinder is composed of a fixed cylinder, a movable cylinder and a baffle, and further comprising: The separation assembly comprises a movable plate disposed on one side of the movable cylinder and a threaded ring disposed on the outer wall of the connecting column, for achieving stable separation of the movable cylinder and the fixed cylinder.

[0007] Furthermore, the fixed cylinder and the movable cylinder have matching grooves on their opposite side walls, and the movable cylinder has protrusions that match the matching grooves fixedly installed on its opposite side wall.

[0008] Furthermore, the movable plate is fixedly mounted at one end of the movable cylinder, and a threaded hole is provided at the center of the movable plate.

[0009] Furthermore, the threaded ring is located at one end of the connecting post near the baffle, and the end of the connecting post near the baffle passes through the movable plate and is adapted to the threaded hole at its center.

[0010] Furthermore, one end of the connecting column is fixedly connected to the center of the holding column, and the other end of the connecting column is rotatably connected to the center of one side of the baffle.

[0011] Furthermore, the outer wall of the baffle is fixedly connected to the inner wall of one end of the fixed cylinder.

[0012] Compared with the prior art, this utility model has the following beneficial effects: By setting up a separation component, the traditional bolt-fastened separation method is changed through the cooperation of the moving plate and the threaded ring. When it is necessary to separate the moving cylinder and the fixed cylinder, the operator only needs to rotate the grip column, and the moving cylinder moves smoothly along the connecting column by using the threaded transmission, avoiding the external force impact generated when disassembling the bolts. At the same time, the adapter groove and protruding strip structure on the opposite side wall of the fixed cylinder and the moving cylinder play a guiding and limiting role in the separation process, further ensuring the stability of the moving cylinder during separation, effectively preventing displacement and loosening of the soil in the remaining fixed cylinder due to the separation action, and maximizing the preservation of the original accumulation state and layered structure of the soil sample, ensuring the integrity of the sample.

[0018] Please see Figure 1-4 .

[0019] This utility model provides a technical solution for a geochemical soil sampling device for geological prospecting: A geochemical soil sampling device for geological prospecting includes a sampling handle 1 and a sampling cylinder 2. The sampling handle 1 is composed of a holding column 101 and a connecting column 102. The sampling cylinder 2 is composed of a fixed cylinder 201, a movable cylinder 202 and a baffle 203. One end of the connecting column 102 is fixedly connected to the center of the holding column 101, and the other end of the connecting column 102 is rotatably connected to the center of one side of the baffle 203. The outer side wall of the baffle 203 is fixedly connected to the inner side wall of one end of the fixed cylinder 201. It also includes a separation component 3 composed of a movable plate 301 disposed on one side of the movable cylinder 202 and a threaded ring 302 disposed on the outer side wall of the connecting column 102, which is used to achieve stable separation of the movable cylinder 202 and the fixed cylinder 201.

[0020] In one embodiment, the fixed cylinder 201 and the movable cylinder 202 have an adapter groove 2011 on their opposite sidewalls, and the movable cylinder 202 has a protrusion 2021 that is adapted to the adapter groove 2011 fixedly provided on its opposite sidewall.

[0021] This design, with the adapter groove 2011 and the raised strip 2021 working together, ensures a tight fit between the fixed cylinder 201 and the moving cylinder 202 during sampling, effectively preventing soil leakage from the gap between the two cylinders and ensuring the integrity and accuracy of the collected soil sample. When separating the moving cylinder 202 from the fixed cylinder 201, the raised strip 2021 slides along the adapter groove 2011, providing precise guidance and preventing the moving cylinder 202 from shaking or shifting during separation. This further reduces disturbance to the soil sample inside the fixed cylinder 201, ensuring that the original accumulation state and layered structure of the soil sample are not damaged, providing a reliable sample basis for subsequent accurate chemical analysis and mineral prediction.

[0022] In one embodiment, a movable plate 301 is fixedly disposed at one end of a movable cylinder 202. A threaded hole 3011 is provided at the center of the movable plate 301. A threaded ring 302 is provided at the end of the connecting post 102 near the baffle 203. The end of the connecting post 102 near the baffle 203 passes through the movable plate 301 and is adapted to the threaded hole 3011 provided at its center.

[0023] This design, through the threaded transmission structure of the threaded hole 3011 and the threaded ring 302, allows the operator to simply fix the fixed cylinder 201 and rotate the gripping column 101 to achieve smooth movement of the moving cylinder 202 along the connecting column 102, completing the separation or connection with the fixed cylinder 201. Compared to the traditional bolt fastening method, it eliminates the need for tedious disassembly of multiple bolts one by one, greatly simplifying the operation process and saving operation time. It also enables quick and efficient separation of the sampling cylinder 2 in complex field environments. At the same time, the threaded transmission has a self-locking characteristic, ensuring a stable connection between the moving cylinder 202 and the fixed cylinder 201 during sampling, preventing accidental separation due to external forces and ensuring smooth sampling. During separation, it also enables controllable and stable movement, reducing the impact on soil samples and improving the practicality and reliability of the entire sampling device.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
