Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil carbon sequestration sampling technology, and in particular to an integrated device for soil carbon sequestration sampling and analysis. Background Technology
[0002] Against the backdrop of a severe global climate change situation, soil carbon sinks, as a key link in the carbon cycle of terrestrial ecosystems, play a vital role in regulating atmospheric carbon dioxide concentration and mitigating the greenhouse effect. Accurate monitoring and assessment of soil carbon sink levels have become a core basis for countries to address climate change and formulate carbon neutrality strategies. Driven by this need, integrated soil carbon sink sampling and analysis equipment has emerged. It aims to provide reliable data support for soil carbon sink research through efficient and precise technical means, contributing to ecological environmental protection and sustainable development.
[0003] Soil carbon sequestration detection technology typically employs a step-by-step approach. First, soil samples are collected from the target area using manual or semi-automatic sampling tools, such as soil augers and sampling shovels. These samples are then transported back to the laboratory where specialized analytical instruments, such as organic carbon analyzers and elemental analyzers, are used for sample pretreatment and index detection. The entire process relies heavily on manual labor, from sample collection and transportation to analysis. This is not only time-consuming but also prone to introducing errors during sample transfer and processing, affecting the accuracy and reliability of the test results.
[0004] In existing technologies, manual operation during the sampling process makes it difficult to ensure the consistency of sampling depth and sample volume each time; during sample transportation, environmental factors may cause changes in sample properties; and in the laboratory analysis stage, sample pretreatment, instrument operation, and other steps still require manual intervention, which is not only inefficient but also unable to achieve real-time dynamic monitoring of soil carbon sequestration. Therefore, an integrated soil carbon sequestration sampling and analysis device is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An integrated soil carbon sequestration sampling and analysis device includes a housing, a sampling mechanism and a transfer mechanism located at the bottom inner side of the housing, and a detection needle fixedly connected to the top inner side of the housing. The transfer mechanism includes a fixing plate, the bottom of which is fixedly connected to the bottom inner side of the housing, and a support frame fixedly connected to the top of the fixing plate. Two connecting blocks are fixedly connected to the top two sides of the support frame.

A metering base one is fixedly connected to the other side of the bottom of the inner side of the outer shell directly below the discharge port.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, by driving the coordinated work of components such as cylinders and motors, a series of operations including soil sampling, transfer, and testing are automated. The entire process requires minimal human intervention, which not only improves work efficiency but also reduces the risk of human error. Furthermore, integrating sampling, transfer, and testing functions into a single device reduces the space requirements and cumbersome procedures associated with traditional multi-device setups, making the equipment more compact and efficient.
[0024] 2. In this invention, during the sampling process, the rotating screw pulls the soil sample into the connecting cylinder, while the connecting cylinder rotates within the fixed ring via the sliding block two. This design ensures that the screw pull can uniformly collect soil samples from different directions, avoiding sampling deviation and guaranteeing the representativeness of the collected samples. Compared to traditional single-direction sampling methods, this method more accurately reflects the actual soil conditions in the sampling area, providing a reliable data foundation for subsequent soil carbon sequestration analysis.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1 to 3 This utility model provides an embodiment of an integrated soil carbon sequestration sampling and analysis device, comprising a shell 1, which is made of a high-strength, corrosion-resistant alloy material, such as aluminum alloy or stainless steel, capable of resisting erosion in complex outdoor environments and ensuring long-term stable operation of the device. A sampling mechanism is located at the bottom inner side of the shell 1, and a transfer mechanism is also located at the bottom inner side of the shell 1. A detection needle 3 is fixedly connected to the top inner side of the shell 1. The transfer mechanism includes a fixing plate 10, the bottom of which is fixedly connected to the bottom inner side of the shell 1. A support frame 4 is fixedly connected to the top of the fixing plate 10. The support frame 4 is a frame structure composed of multiple metal rods, possessing sufficient strength and stability. Two connecting blocks 6 are fixedly connected to the top two sides of the support frame 4. Cylinders are installed inside the two connecting blocks 6. A protective shell 7 is fixedly connected to the drive end of the cylinder inside the connecting block 6. A [missing information - likely a device name] is fixedly connected inside the protective shell 7. The clamping assembly includes a motor 11, which is externally fixedly connected to the inside of the protective shell 7. A rotating gear 12 is fixedly connected to the drive end of the motor 11, which drives the rotating gear 12. The rotating gear 12 is manufactured using high-precision machining technology, with precise tooth profile, and meshes tightly with the rack 13. Two racks 13 are slidably connected inside the protective shell 7. The tooth surfaces of the racks 13 are hardened to improve wear resistance and can transmit greater force when meshing with the rotating gear 12. The outside of the racks 13 meshes with the outside of the rotating gear 12. A sliding block 8 is fixedly connected to the outside of the racks 13. The sliding block 8 is made of wear-resistant engineering plastic or metal, and its shape matches the slide rail on the outside of the protective shell 7, allowing it to slide flexibly on the slide rail. A fixing clamp 9 is fixedly connected to the outside of the sliding block 8, and the outside of the sliding block 8 is slidably connected to the outside of the protective shell 7.
[0033] Reference Figure 1 , Figure 2 and Figure 4 The sampling mechanism includes a fixed ring 21, the bottom of which is fixedly connected to the bottom inner side of the outer casing 1. A sliding block 22 is rotatably connected inside the fixed ring 21. The fixed ring 21 is welded to the bottom inner side of the outer casing 1, serving a fixing and supporting function. A connecting cylinder 2 is fixedly connected to the outside of the sliding block 22. The connecting cylinder 2 is a cylindrical structure made of high-strength and relatively tough plastic or metal material, used to hold the collected soil samples. The sliding block 22 is made of wear-resistant engineering plastic material and contacts the fixed ring 21 via ball bearings or a slide rail, reducing friction during rotation and ensuring that the connecting cylinder 2 rotates smoothly during sampling, thereby achieving uniform sampling. A support ring 1 is fixedly connected to the top of the connecting cylinder 2. 5. The support ring 15 has multiple mounting holes for easy fixing and disassembly of the pushing assembly. A pushing assembly for sampling is fixedly connected to the top of the support ring 15. The pushing assembly includes a pushing cylinder 14, which is externally fixedly connected to the top of the support ring 15. A second motor 16 is fixedly connected to the drive end of the pushing cylinder 14, which drives the second motor 16 to move up and down. A helical rod 19 is fixedly connected to the drive end of the second motor 16, which drives the helical rod 19 to rotate. A pushing column 17 is fixedly connected to the outside of the second motor 16. The pushing column 17 is a cylindrical rod, one end of which is fixedly connected to the second motor 16, and the other end passes through the through hole at the top of the connecting cylinder 2 and slides inside the connecting cylinder 2. A limit block is provided on the outside of the pushing column 17 to prevent it from detaching from the connecting cylinder 2 during sliding. Under the action of the push cylinder 14, the push column 17 drives the motor 16 and the screw rod 19 to move up and down, and at the same time plays a guiding role to ensure that the screw rod 19 rises and falls vertically. The outside of the push column 17 is slidably connected to the inside of the connecting cylinder 2. The outside of the push column 17 is fixedly connected to the discharge port 5. The metering base 20 is fixedly connected to the bottom of the inner side of the outer shell 1 directly below the discharge port 5. The metering base 18 is fixedly connected to the bottom of the inner side of the outer shell 1 on the other side directly below the discharge port 5. The thread, pitch and tooth profile of the screw rod 19 can efficiently transport soil samples into the connecting cylinder 2. Its material has good wear resistance and corrosion resistance. The surface is specially treated to prevent soil samples from adhering and is easy to clean.
[0034] Working principle: The cylinder 14 drives the motor 16, the push column 17, and the screw rod 19 downwards. When the preset sampling depth is reached, the motor 16 drives the screw rod 19 to rotate. During the rotation of the screw rod 19, the soil sample is drawn into the connecting cylinder 2. During the sampling process, the connecting cylinder 2 rotates within the fixed ring 21 through the sliding block 22 to ensure that the screw rod 19 can collect the soil sample evenly. After the sampling is completed, the cylinder 14 drives the components to reset and pushes the sample out through the discharge port 5, lifting the collected soil sample to a suitable position inside the equipment.
[0035] The cylinder inside the connecting block 6 drives the protective shell 7 to move downwards. When the protective shell 7 moves to the appropriate position, the motor 11 drives the rotating gear 12 to rotate. The rotating gear 12 meshes with the rack 13, causing the two racks 13 to move relative to each other. The sliding block 8 slides outside the protective shell 7, thereby causing the fixing clamp 9 to open. Subsequently, the protective shell 7 continues to move downwards, causing the fixing clamp 9 to clamp the sample tube and move it from the metering base 20 to the metering base 18. The detection needle 3 descends and is inserted into the soil sample on the metering base. The sensor built into the detection needle 3 begins to detect and analyze indicators such as carbon content and carbon form in the soil sample. The detection data is transmitted to the equipment's data processing system in real time. The data processing system processes, analyzes, and stores the data, and finally generates an analysis report related to soil carbon sequestration.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
