Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, and in particular to a portable soil stratification sampling device for geological exploration. Background Technology

[0002] In the field of geological exploration, accurate and efficient stratified soil sampling is crucial. Soil stratification sampling provides key data for studying soil structure, composition, and properties, contributing to a deeper understanding of geological structures, mineral distribution, and ecological conditions. In recent years, with the continuous deepening of geological exploration and the increasing demand for more refined methods, higher requirements have been placed on the performance and functionality of portable soil stratification sampling devices.

[0003] Existing technologies, such as the utility model disclosed in patent CN 218823322 U, describe a soil sampler comprising a vertical rod with a through groove on its surface. A horizontal rod is housed within the cavity of the through groove, and connecting blocks are fixedly connected to both ends of the horizontal rod. A vertical plate is fixedly connected to the opposite side of each connecting block, and a threaded sleeve is threaded through the surface of the vertical plate. A threaded rod is threaded onto the inner wall of the threaded sleeve. This utility model, through the combination of the vertical rod, through groove, horizontal rod, connecting blocks, vertical plate, threaded sleeve, threaded rod, fixing sleeve, handle, drill bit, and sampling groove, achieves the advantage of combining drilling and sampling. It solves some defects in previous soil samplers, such as the lack of combined drilling and sampling advantages, increased sampling difficulty, reduced user efficiency, and inability to meet current market demands. These problems reduce the practicality and usability of the soil sampler.

[0004] When using the above technical solution,

[0005] (1) It is difficult to accurately sample soil at different depths. Due to the limitations of its structural design, it is difficult to ensure the independence and integrity of each soil sample when going to different depths of the soil. This can easily lead to soil at different depths being mixed together, affecting the accurate analysis of the composition and properties of each soil layer.

[0006] (2) The device is not stable during use. When inserted into the soil, it is easy to shake, which makes the location of the collected soil sample inaccurate. Moreover, it is difficult to stably penetrate to the required depth in some hard or complex soil environments, which affects the smooth progress of the sampling work.

[0007] To address the aforementioned problems, this utility model provides a portable soil stratification sampling device for geological exploration. Utility Model Content

[0008] The purpose of this invention is to solve the problems of difficulty in accurate stratified sampling and poor stability in the existing technology, and to propose a portable soil stratification sampling device for geological exploration.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a portable soil stratification sampling device for geological exploration, comprising a supporting top plate, a stratification sampling mechanism, and a stable connection mechanism, wherein the stratification sampling mechanism is threadedly connected to the top of the supporting top plate, and the stable connection mechanism is fixedly connected to the bottom of the supporting top plate. The stratification sampling mechanism includes through holes opened on both sides of the supporting top plate, and a transmission component is threadedly connected to the top of the through holes.

[0010] The stratified sampling mechanism includes an outer sampling cylinder and an inner sampling cylinder, with the inner sampling cylinder rotatably connected to the interior of the outer sampling cylinder.

[0011] The inner bottom wall of the outer sampling cylinder is fixedly connected to a bearing, and the inner sampling cylinder is rotatably connected to the inside of the outer sampling cylinder through the bearing. The outer surfaces of the outer sampling cylinder and the inner sampling cylinder are provided with holes and slots at four equal intervals. The inner cavity of the inner sampling cylinder is fixedly connected with layered partitions at three equal intervals. The inner sampling cylinder is divided into four sampling chambers by the layered partitions.

[0012] Furthermore, the transmission assembly includes a connecting frame threaded to the top of the supporting top plate, with bolts threaded to both sides of the connecting frame, and the connecting frame is threaded to the top of the supporting top plate by the bolts.

[0013] Furthermore, a servo motor is fixedly connected inside the connecting frame, and a connecting plate is fixedly connected to the output end of the servo motor. Connecting parts are threaded to both sides of the connecting plate, and the sampling outer cylinder is threaded to the bottom of the connecting plate through the connecting parts.

[0014] Furthermore, a rotating slot is provided on the top of the outer surface of the sampling outer cylinder, and a rotating handle is fixedly connected to the top of the sampling inner cylinder, the rotating handle being engaged inside the rotating slot.

[0015] Furthermore, a spiral blade is fixedly connected to the top of the sampling outer cylinder, and a sharp head is fixedly connected to the bottom of the spiral blade.

[0016] Furthermore, the stabilizing connection mechanism includes connecting columns fixedly connected to the four corners of the bottom of the supporting top plate, a stabilizing base plate fixedly connected to the bottom of the connecting columns, sampling holes on both sides of the stabilizing base plate, and connecting ground cones fixedly connected to the four corners of the bottom of the stabilizing base plate.

[0017] Furthermore, the stabilizing connection mechanism includes inclined support plates threaded to both sides of the supporting top plate, with limiting components threaded to both sides of the inclined support plates, and the inclined support plates threaded to both sides of the supporting top plate through the limiting components. A ground connector is threaded to the bottom of the inclined support plates, and the ground connector and the inclined support plates are symmetrically arranged on both sides of the supporting top plate.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. In this utility model, the arrangement of an outer sampling cylinder, an inner sampling cylinder, and a layered partition effectively enables stratified sampling of soil at different depths. During the sampling process, soil enters different sampling chambers of the inner sampling cylinder through the holes and grooves on the outer and inner sampling cylinders, reducing disturbance to the original stratified structure of the soil and ensuring the authenticity and accuracy of the collected soil samples. This provides a reliable sample basis for subsequent soil analysis. The layered partition divides the inner sampling cylinder into four sampling chambers, thereby achieving effective stratified sampling of soil at different depths. The servo motor provides stable and controllable power to drive the outer sampling cylinder to rotate, ensuring smooth sampling operations under different soil conditions.

[0020] 2. In this utility model, the spiral blade, the inclined support plate, and the connecting ground cone allow the sharp head to easily penetrate the soil surface. The spiral blade further breaks up the soil by rotating, reducing the resistance of the soil to the insertion of the device. This allows the device to penetrate into soil layers of different depths more smoothly and quickly, improving sampling efficiency. The inclined support plate and the connecting ground cone work together to firmly fix the device on the ground, reducing shaking and displacement of the device during sampling and preventing tilting during sampling, thus ensuring the smooth progress of the sampling work.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a portable soil stratification sampling device for geological exploration, including a supporting top plate 1, a stratification sampling mechanism 2 and a stable connection mechanism 3. The stratification sampling mechanism 2 is threadedly connected to the top of the supporting top plate 1, and the stable connection mechanism 3 is fixedly connected to the bottom of the supporting top plate 1. The stratification sampling mechanism 2 includes through holes 21 opened on both sides of the supporting top plate 1, and a transmission component 22 is threadedly connected to the top of the through holes 21.

[0030] The specific setup and function of its layered sampling mechanism 2 and stable connection mechanism 3 will be explained below.

[0031] In this embodiment: the layered sampling mechanism 2 includes an outer sampling cylinder 23 and an inner sampling cylinder 24, with the inner sampling cylinder 24 rotatably connected to the inside of the outer sampling cylinder 23.

[0032] A bearing 25 is fixedly connected to the inner bottom wall of the sampling outer cylinder 23. The sampling inner cylinder 24 is rotatably connected to the inside of the sampling outer cylinder 23 through the bearing 25. The outer surfaces of the sampling outer cylinder 23 and the sampling inner cylinder 24 are provided with holes and slots 26 at four equal intervals. The inside of the sampling inner cylinder 24 is fixedly connected with layered partitions 27 at three equal intervals. The sampling inner cylinder 24 is divided into four sampling chambers 28 by the layered partitions 27.

[0033] The effect achieved by the above components is as follows: the layered partition 27 divides the sampling inner cylinder 24 into four sampling chambers 28, each sampling chamber 28 corresponding to soil collection at a specific depth range. In actual operation, as the device gradually penetrates the soil, soil at different depths enters the corresponding sampling chamber 28 through the slots 26 in sequence, thereby achieving layered sampling of the soil and providing reliable samples for subsequent compositional analysis and research of soil at different depths.

[0034] Specifically, the transmission assembly 22 includes a connecting frame 221 threaded to the top of the supporting top plate 1, and bolts 222 threaded to both sides of the connecting frame 221. The connecting frame 221 is threaded to the top of the supporting top plate 1 by the bolts 222.

[0035] The effect achieved by the above components is that the connecting frame 221 can be disassembled during the transportation or storage of the device to reduce the size of the device and make it easier to carry. During use, it can be quickly and firmly installed to ensure a stable connection between the transmission component 22 and the support top plate 1, providing a foundation for the normal operation of subsequent components.

[0036] Specifically, a servo motor 223 is fixedly connected inside the connecting frame 221, and a connecting plate 224 is fixedly connected to the output end of the servo motor 223. Connecting parts 225 are threadedly connected to both sides of the connecting plate 224, and the sampling outer cylinder 23 is threadedly connected to the bottom of the connecting plate 224 through the connecting parts 225.

[0037] The effect achieved by the above components is that during the soil sampling process, the servo motor 223 can precisely control the rotation speed and rotation angle according to different soil hardness and sampling depth requirements, ensuring that the outer sampling cylinder 23 can smoothly penetrate into the soil and stop rotating at a suitable position so that the soil can enter the inner sampling cylinder 24 through the slot 26, which greatly improves the accuracy and efficiency of sampling.

[0038] Specifically, a rotating slot 29 is provided on the top of the outer surface of the sampling outer cylinder 23, and a rotating handle 210 is fixedly connected to the top of the sampling inner cylinder 24. The rotating handle 210 is engaged inside the rotating slot 29.

[0039] The effect achieved by the above components is as follows: rotating the handle 210 can rotate the sampling inner cylinder 24, so that during the soil sampling process, the sampling outer cylinder 23 and the sampling inner cylinder 24 are misaligned with each other, preventing soil from falling into the sampling chamber 28 during the drilling process. After reaching the specified depth, rotating the handle 210 to rotate the sampling inner cylinder 24 allows the soil at the corresponding depth to enter the corresponding sampling chamber 28.

[0040] Specifically, a spiral blade 211 is fixedly connected to the top of the sampling outer cylinder 23, and a sharp head 212 is fixedly connected to the bottom of the spiral blade 211.

[0041] The effect achieved by the above-mentioned components is as follows: the sharp head 212 can penetrate the soil surface first, reducing the initial resistance of the soil to the insertion of the device. As the device continues to go deeper, the spiral blade 211, when the servo motor 223 drives the sampling outer cylinder 23 to rotate, breaks up the soil by rotating and pushes the soil away, creating conditions for the device to go deeper into the soil.

[0042] Specifically, the stabilizing connection mechanism 3 includes connecting columns 31 fixedly connected to the four corners of the bottom of the supporting top plate 1, a stabilizing base plate 32 fixedly connected to the bottom of the connecting columns 31, sampling holes 33 on both sides of the stabilizing base plate 32, and connecting cones 34 fixedly connected to the four corners of the bottom of the stabilizing base plate 32.

[0043] The above-mentioned components achieve the following effects: the connecting cone 34 can stably fix the device on the ground when the device is in use, preventing the device from shifting or tipping over due to soil reaction force or slight shaking by the operator during the sampling process; the sampling holes 33 opened on both sides of the stable base plate 32 correspond to the slots 26 on the outer sampling cylinder 23 and the inner sampling cylinder 24, ensuring that the soil is not obstructed when entering the inner sampling cylinder 24, thus ensuring the smooth progress of the sampling process.

[0044] Specifically, the stable connection mechanism 3 includes inclined support plates 35 threadedly connected to both sides of the supporting top plate 1. Limiting members 36 are threadedly connected to both sides of the inclined support plates 35. The inclined support plates 35 are threadedly connected to both sides of the supporting top plate 1 through the limiting members 36. A ground connector 37 is threadedly connected to the bottom of the inclined support plates 35. The ground connector 37 and the inclined support plates 35 are symmetrically arranged on both sides of the supporting top plate 1.

[0045] The above components achieve the following effects: the ground connector 37 is used to connect the inclined support plate 35 to the ground, providing a stable support point for the inclined support plate 35. The inclined support plate 35 and the ground connector 37, which are symmetrically arranged on both sides, can support and fix the device from multiple directions, effectively preventing the device from shaking or tilting during the sampling process, and ensuring the stable operation of the sampling work.

[0046] Working principle: When carrying out soil stratification sampling, the device is first moved to the predetermined sampling location. Through manual operation, the connecting cone 34 at the bottom of the stabilizing base plate 32 is inserted into the ground. At the same time, the angle of the inclined support plate 35 is adjusted, and the ground connector 37 is fixed on the ground to ensure that the entire device is stably fixed on the ground.

[0047] The servo motor 223 in the transmission assembly 22 is started. The servo motor 223 drives the connecting plate 224 to rotate, which in turn drives the sampling outer cylinder 23 to rotate through the connecting piece 225. During the rotation, the spiral blade 211 and sharp head 212 at the top of the sampling outer cylinder 23 gradually penetrate the soil, allowing the device to penetrate deeper into the soil.

[0048] When the device reaches a predetermined sampling depth, the servo motor 223 stops rotating. At this time, soil enters the sampling inner cylinder 24 through the corresponding slots 26 on the outer sampling cylinder 23 and the inner sampling cylinder 24. The operator can adjust the position of the sampling inner cylinder 24 by rotating the handle 210, so that different sampling chambers 28 are aligned with the slots 26 in sequence, realizing the stratified collection of soil at different depths. Rotating the handle 210 can rotate the sampling inner cylinder 24, so that during the soil sampling process, the slots 26 of the outer sampling cylinder 23 and the sampling inner cylinder 24 are misaligned, preventing soil from falling into the sampling chamber 28 during drilling. After reaching the designated depth, rotating the handle 210 to sample the inner cylinder 24 allows soil at the corresponding depth to enter the corresponding sampling chamber 28.

[0049] After collection, the servo motor 223 is restarted and reversed to remove the device from the soil. Finally, the device is disassembled, the sampling inner cylinder 24 is removed, and the soil samples collected in different sampling chambers 28 are subjected to subsequent analysis and research. Throughout the process, the stable connection mechanism 3 ensures the stability of the device during sampling.
