Description

Technical Field

[0001] The present application belongs to the field of Gobi surface sampling technology, and specifically relates to a Gobi surface multi-depth quantitative sampling device and a control method. Background Art

[0002] Gobi landforms are a subtype of desert, characterized by gravel and coarse sand, formed by long-term weathering, water erosion, and wind action. They are primarily composed of gravel and coarse sand, with sparse vegetation. Their formation process is primarily due to the physical weathering of rocks into gravel in an arid climate. Wind then transports loose surface material, leaving coarse gravel covering the surface and gradually forming the Gobi. Gobi landforms have a significant impact on ecology and human activities. Their fragile ecosystems make it difficult for vegetation to recover, making them a major source of sandstorms. However, the Gobi's underlying surface may contain rich mineral resources, such as oil, natural gas, and metal ores. Furthermore, the Gobi's unique landscape has attracted numerous tourists, driving the development of local tourism. However, tourism development also faces the challenge of balancing ecological protection with resource utilization.

[0003] Accurately obtaining quantitative soil samples at different depths on the Gobi surface is of great significance for studying the ecological evolution of soil in the Gobi region, water resource management, desertification prevention and control, mineral resource exploration and other fields. At present, traditional soil sampling methods and devices face many challenges when used in the Gobi region. Conventional surface soil sampling tools, such as shovels and soil drills, are difficult to penetrate the hard gravel layer and cannot achieve simultaneous sampling at multiple depths, resulting in low efficiency. For stratified sampling, existing equipment mostly uses manual segmented excavation, which is not only time-consuming and labor-intensive, but also prone to sample contamination and inter-layer disturbance, making it difficult to ensure the representativeness and quantitative accuracy of the samples. In addition, the Gobi region has a harsh climate, with strong winds and sand and large temperature differences. The existing sampling devices lack effective protection measures. During the sampling process, samples are easily disturbed by the outside world, resulting in data distortion. Summary of the Invention

[0004] The purpose of this application is to provide a Gobi surface multi-depth quantitative sampling device and a control method to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, this application provides the following technical solutions:

[0014] Preferably, the plurality of baffles are respectively arranged on the inner sides of the plurality of slots, and the plurality of baffles are respectively arranged on the outer sides of the plurality of sampling boxes.

[0015] A Gobi surface multi-depth quantitative sampling device and control method, the method comprising the following steps:

[0016] S1 Sampling preparation: determine the sampling depth and sampling location, carry the corresponding number of extension rods according to the sampling depth, and prepare multiple dedicated soil sample boxes;

[0017] S2 Sampling device installation: Divide the sampling area according to the area and uniformity of the Gobi land, determine the number of sampling points, and set up the device at the sampling point. Install the limit seat on the sampling point through multiple anchor nails, then install the extension rod and sampling assembly on the drilling machine, and then set up the installed device above the limit seat;

[0018] S3 sampling operation, using a drilling machine to drill the sampling assembly and extension rod into the Gobi surface, disassemble and install the extension rod of the corresponding depth according to the sampling depth, drill the sampling assembly into the corresponding depth, and then take samples through the sampling assembly;

[0019] S4 sample storage: the taken samples are placed into multiple dedicated soil sample boxes, and the corresponding sample number, sampling date, sampling point coordinates and soil depth are marked on the container.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] (1) By setting up a sampling assembly, when sampling on the surface, the hydraulic cylinder drives the column to move downward, so that the column drives multiple bosses to move downward, and the multiple sampling boxes arranged inside the sampling tube are pushed outward by the multiple bosses, so that multiple sampling boxes on both sides are moved out from the corresponding slots, and the sampling boxes on both sides are inserted into the soil, so that sampling is performed through the sampling boxes on both sides, so that quantitative soil samples are collected inside the sampling boxes. This method can obtain soil samples from multiple locations at the same time, avoid the randomness of single-point sampling, ensure that the collected soil samples more comprehensively reflect the regional soil characteristics, improve the representativeness of the samples and the reliability of the analysis results, and through the multiple sampling boxes arranged inside the sampling tube, the soil at different depths of the surface can be sampled at one time, which is suitable for multiple scientific research and detection scenarios such as soil profile research and vertical distribution detection of pollutants, and broadens the application range of the equipment.

[0022] (2) By setting up a sampling component and a shielding component, when sampling, the hydraulic cylinder drives the column to move downward, so that the column drives multiple baffles to move at the same time, and moves the baffles to the bottom of the sampling box, so as not to affect the removal of the sampling box; subsequently, the hydraulic cylinder drives the column to move upward, and the sampling boxes on both sides are reset under the action of the spring, and at the same time, the column drives multiple baffles to reset, so that the baffles cover the outside of the sampling box; with this design, the sampling component and the shielding component are linked by the hydraulic cylinder and the column. During the sampling process, the column moves downward and automatically drives the baffles to move under the sampling box, creating space for the sampling box to be removed; after the sampling is completed, the column moves upward and can simultaneously drive the baffles and the sampling box to reset, without the need for manual adjustment of the component position; at the same time, after the sampling box completes soil collection, the baffle automatically covers the outside of the sampling box, forming a physical barrier, effectively preventing external debris, dust, rainwater, etc. from contaminating the sample, maximizing the integrity and purity of the sample, and providing a reliable sample for subsequent accurate analysis.

[0033] Example 1:

[0034] See also Figure 1 - Figure 3 As shown, the Gobi surface multi-depth quantitative sampling device and control method include:

[0035] A drilling machine 1 and a limit seat 2 provided at the bottom of the drilling machine 1, as well as a plurality of extension rods 4 and a sampling assembly 5 installed at the bottom end of the drilling machine 1;

[0036] As can be seen from the above, the drilling machine 1 (a prior art product, on which a stroke engine is installed) provides power for drilling during sampling, and the limit seat 2 is used to facilitate limiting during subsequent drilling to avoid displacement during drilling sampling. By splicing multiple extension rods 4, the drilling depth can be adjusted conveniently, thereby facilitating subsequent sampling through the sampling component 5.

[0037] A plurality of anchors 3 are mounted on the limiting seat 2, and the sampling assembly 5 includes a sampling barrel 51. Connectors 6 are provided at the bottom of the drilling machine 1, at both ends of the plurality of extension rods 4, and at the top of the sampling barrel 51.

[0038] As can be seen from the above, the limit seat 2 is installed by multiple anchor nails 3, and the device is conveniently spliced ​​through the drilling machine 1, multiple extension rods 4 and the connector 6 on the sampling tube 51.

[0039] Specifically, regarding the above-mentioned sampling component 5, refer to Figure 3 and Figure 4 As shown, the sampling assembly 5 further includes a plurality of notches 52, which are symmetrically and equidistantly provided on the sampling tube 51. A hydraulic cylinder 53 is mounted on the top of the inner side of the sampling tube 51, and a column 54 is mounted on the bottom end of the hydraulic cylinder 53. A plurality of transverse plates 55 are fixedly connected to the interior of the sampling tube 51, and sampling boxes 56 are symmetrically provided on the top of the plurality of transverse plates 55. A plurality of bosses 57 are fixedly connected to the column 54.

[0040] As can be seen from the above, when sampling, the hydraulic cylinder 53 drives the column 54 to move, so that the column 54 drives the multiple bosses 57 to move downward, and the bosses 57 push the sampling boxes 56 on both sides to move outward, so that the sampling boxes 56 on both sides are moved out from the multiple slots 52, and the sampling boxes 56 on both sides are inserted into the soil, thereby sampling is performed through the sampling boxes 56 on both sides.

[0041] Specifically, regarding the above-mentioned sampling component 5, refer to Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, the sampling assembly 5 further includes a plurality of through holes 58, which are respectively provided on the plurality of transverse plates 55. The plurality of transverse plates 55 have grooves 59 symmetrically provided on the tops thereof. The interiors of the grooves 59 on both sides are fixedly connected to limit rods 510, and the limit rods 510 on both sides are respectively installed with springs 511, and the limit rods 510 on both sides are respectively provided with movable plates 512.

[0042] As can be seen from the above, when sampling, the sampling boxes 56 on both sides move, so that the bottom movable plate 512 moves with the sampling box 56, thereby squeezing the spring 511 through the movable plate 512. After the subsequent sampling is completed, the spring 511 rebounds and resets, so that the sampling boxes 56 on both sides are reset.

[0043] Preferably, a plurality of bosses 57 are respectively provided on the top of a plurality of sampling boxes 56 , and the bosses 57 are provided at the top position between the sampling boxes 56 on both sides;

[0044] As can be seen from the above, the boss 57 is arranged at the top position between the sampling boxes 56 on both sides, so that the boss 57 can push out the sampling boxes 56 on both sides when it moves downward.

[0045] Preferably, the upright post 54 is arranged inside the through hole 58, and the sampling boxes 56 on both sides are respectively installed on the top of the movable plate 512;

[0046] As can be seen from the above, the column 54 is set inside the through hole 58 so that the column 54 can move inside the through hole 58, and the sampling boxes 56 on both sides are installed on the top of the movable plate 512 so that the subsequent sampling boxes 56 can move with the movable plate 512.

[0047] Example 2:

[0048] refer to Figure 5 and Figure 6 As shown, a shielding assembly 7 is provided inside the sampling tube 51, and the shielding assembly 7 includes a plurality of baffles 71, and the plurality of baffles 71 are connected to the column 54 through a connecting rod 72;

[0049] As can be seen from the above, multiple baffles 71 are connected to the column 54 through the connecting rod 72, so that when the column 54 moves, it can simultaneously drive the multiple baffles 71 to move. When the hydraulic cylinder 53 drives the column 54 to move upward, the baffle 71 resets and moves to the outside of the sampling box 56; when the hydraulic cylinder 53 drives the column 54 to move downward, the baffle 71 moves to the bottom of the sampling box 56, thereby not affecting the subsequent removal of the sampling box 56.

[0050] Preferably, the plurality of baffles 71 are respectively disposed inside the plurality of notches 52 , and the plurality of baffles 71 are respectively disposed outside the plurality of sampling boxes 56 ;

[0051] As can be seen from the above, the baffle 71 is arranged inside the notch 52 so that the baffle 71 just blocks the inside of the notch 52 after being reset and is located outside the sampling box 56 .
