Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a soil environment detection sampling device. Background Art

[0002] Soil testing is the analysis and evaluation of soil samples to determine the content of nutrients and harmful substances in the soil. By accurately evaluating the nutrients and harmful substances in the soil, we can better manage soil resources, ensure the quality and safety of agricultural products, and reduce the harm caused by soil pollution to the environment and humans. It is of great significance to agricultural production, environmental protection and human health. The core goal of soil environmental testing is to obtain real and reliable soil data. The sampling device is a key tool for obtaining soil samples. Its performance and accuracy directly determine the reliability of the test results.

[0003] When existing soil environmental testing sampling devices sample deep soil, as they gradually penetrate deeper into the soil, they first contact shallow soil, resulting in some soil from depths other than the target depth being inevitably mixed into the sampling device. These soils may carry physical and chemical properties and pollutant information that are completely different from those of the deep soil, thus becoming interference factors and affecting the accuracy and reliability of the final test results.

[0004] Therefore, a soil environment detection sampling device is proposed. Utility Model Content

[0023] like Figures 1 to 3As shown, a soil environment detection sampling device includes a base 1, a through groove 2 is opened on the surface of the base 1, a support column 3 is fixedly installed on the top surface of the base 1, a lifting mechanism 4 is provided on the surface of the support column 3, a connecting rod 5 is fixedly installed on the surface of the lifting mechanism 4, a blocking column 6 is fixedly installed on the bottom surface of the connecting rod 5, a soil sampling auxiliary mechanism 7 is provided on the surface of the connecting rod 5, a soil sampling pipe 8 is fixedly installed on the surface of the soil sampling auxiliary mechanism 7, the blocking column 6 is arranged inside the soil sampling pipe 8, and a blocking head 9 is fixedly installed on the bottom surface of the blocking column 6.

[0024] Specifically, the collection device is placed on the soil surface to be collected, and the lifting mechanism 4 on the surface of the supporting column 3 drives the connecting rod 5 and the blocking column 6, the soil-taking auxiliary mechanism 7 and the soil-taking pipe 8 on its surface to descend and gradually penetrate into the soil, and the non-target soil is blocked by the blocking head 9 to prevent the soil of the non-target layer from entering the soil-taking pipe 8 and affecting the final detection result. When the soil-taking pipe 8 reaches the target layer of soil, the soil-taking auxiliary mechanism 7 on the surface of the connecting rod 5 drives the soil-taking pipe 8 to separate from the blocking column 6 and the blocking head 9 and gradually descend into the soil, thereby achieving the purpose of sampling the soil of the target layer. After the soil sampling is completed, the connecting rod 5, the blocking column 6 and the soil-taking pipe 8 are driven to rise by the lifting mechanism 4, and the soil-taking auxiliary mechanism 7 drives the soil-taking pipe 8 to rise along the surface of the blocking head 9, so that the blocking head 9 can push out the soil inside the soil-taking pipe 8, thereby completing the sampling and performing the detection, which is beneficial to the accuracy and reliability of the final detection result.

[0025] like Figures 1 to 3 As shown, the bottom surface of the base 1 is fixedly mounted with support legs 10 , and there are four support legs 10 arranged in front, back, left and right directions.

[0026] Specifically, the provision of the support legs 10 enables the sampling device to be placed more stably on the soil surface, which is beneficial to the stability of the sampling process.

[0027] like Figures 1 to 3 As shown, the blocking head 9 has an inverted cone structure, the top surface diameter of the blocking head 9 is the same as the inner wall diameter of the soil sampling tube 8, and the diameter of the blocking column 6 is smaller than the inner wall diameter of the soil sampling tube 8.

[0028] Specifically, the inverted cone-shaped blocking head 9 facilitates reducing the friction of the soil when penetrating into the soil, making sampling easier and more convenient, and reducing losses. The top surface diameter of the blocking head 9 is the same as the inner wall diameter of the soil sampling tube 8, which facilitates more comprehensive blocking of non-target layer soil, which is beneficial to the accuracy and reliability of the final result.

[0029] like Figures 1 to 3 As shown, the through groove 2 is located directly below the soil borrowing pipe 8, and the diameter of the through groove 2 is larger than the diameter of the soil borrowing pipe 8.

[0030] Specifically, the through groove 2 is located directly below the soil-boring pipe 8 and the diameter of the through groove 2 is larger than the diameter of the soil-boring pipe 8, which reserves sufficient space for the soil-boring pipe 8 to descend deep into the soil, which is beneficial to the stability of the overall structure.

[0031] like Figures 1 to 3 As shown, the lifting mechanism 4 includes a slide groove 401, which is opened on the surface of the support column 3, and a first motor 402 is fixedly installed on the top surface of the support column 3. The output end of the first motor 402 is fixedly connected to a first threaded rod 403, and the first threaded rod 403 is rotatably installed on the inner wall surface of the slide groove 401. A lifting rod 404 is threadedly sleeved on the surface of the first threaded rod 403, and the lifting rod 404 is slidably installed on the inner wall surface of the slide groove 401, and the connecting rod 5 is fixedly installed on the bottom surface of the lifting rod 404.

[0032] Specifically, the output end of the first motor 402 rotates to drive the first threaded rod 403 to rotate, thereby driving the lifting rod 404, which is threadedly mounted on the surface of the first threaded rod 403 and slidably installed on the inner wall surface of the slide groove 401, to move up and down, thereby driving the connecting rod 5, the blocking column 6 and the soil sampling pipe 8 to rise and fall, which is conducive to the subsequent collection of soil at different depths.

[0033] like Figures 1 to 3 As shown, the soil-taking auxiliary mechanism 7 includes a second motor 701, which is fixedly mounted on the top surface of the connecting rod 5. The output end of the second motor 701 is fixedly connected to the second threaded rod 702. The second threaded rod 702 is rotatably arranged relative to the bottom surface of the connecting rod 5 and the top surface of the blocking head 9. A guide rod 703 is fixedly connected between the opposite surfaces of the connecting rod 5 and the blocking head 9. A moving block 704 is fixedly mounted on the inner wall surface of the soil-taking pipe 8. There are two moving blocks 704, which are arranged on the left and right. The left moving block 704 is threadedly mounted on the surface of the second threaded rod 702, and the right moving block 704 is slidably mounted on the surface of the guide rod 703.

[0034] Specifically, the second threaded rod 702 is driven to rotate by the output end of the second motor 701, thereby driving the moving block 704 threadedly mounted on the surface of the second threaded rod 702 to move up and down, and the right moving block 704 slides up and down along the surface of the guide rod 703, thereby driving the soil sampling pipe 8 fixedly installed on the surface of the moving block 704 to move up and down, so that the blocking head 9 can move to the inside of the soil sampling pipe 8, making it easier for the soil sampling pipe 8 to sample the target soil layer, avoiding the mixing of soil from shallow non-target soil layers in the process of penetrating the soil, which is beneficial to the accuracy and reliability of the final detection results.

[0035] To sum up: the collection device is placed on the surface of the soil to be collected, and the lifting mechanism 4 drives the connecting rod 5 and the blocking column 6 on its surface, the soil sampling auxiliary mechanism 7 and the soil sampling tube 8 to descend and gradually penetrate into the soil, and the non-target soil is blocked by the blocking head 9 to prevent the soil of the non-target layer from entering the soil sampling tube 8 and affecting the final detection result. When the soil sampling tube 8 reaches the target layer of soil, the soil sampling auxiliary mechanism 7 drives the soil sampling tube 8 to gradually descend and penetrate into the soil, thereby achieving the purpose of sampling the soil of the target layer. After the soil sampling is completed, the connecting rod 5, the blocking column 6 and the soil sampling tube 8 are driven to rise by the lifting mechanism 4, and the soil sampling auxiliary mechanism 7 drives the soil sampling tube 8 to rise along the surface of the blocking head 9, so that the blocking head 9 can push out the soil inside the soil sampling tube 8, thereby completing the sampling and testing, which is conducive to the accuracy and reliability of the final test results.
