[0002] Mineral-bound organic carbon in wetland soil is one of the important carbon pools in soil and plays a vital role in the global carbon cycle and climate change. Understanding the composition and formation process of mineral-bound organic carbon in wetland soil has become the key to understanding soil carbon dynamics and mitigating climate change. In order to accurately determine the content of mineral-bound organic carbon in wetland soil, it is usually necessary to use soil mineral-bound organic carbon detection equipment to complete the collection and processing of soil samples.

[0003] However, existing soil mineral bound organic carbon detection equipment has certain defects during use. Existing soil mineral bound organic carbon detection equipment lacks flexible sampling components, which limits the sampling ability of the equipment in complex terrain, especially in a changeable environment such as wetlands. Existing soil mineral bound organic carbon detection equipment lacks automated sampling and sample processing procedures, which increases the possibility of human error and reduces work efficiency. Existing soil mineral bound organic carbon detection equipment does not have integrated drying and crushing components and screening components, resulting in a cumbersome and inefficient sample processing process, and is prone to sample loss and contamination during the processing process.

The wetland soil mineral-bound organic carbon detection device integrates the sampling component, the drying and crushing component and The screening component is integrated into one, realizing a one-stop operation from sampling to sample processing to screening. Since the equipment can continuously process samples, the exposure and contamination of samples during the processing process are reduced. In particular, the screening component is located directly below the drying and crushing component, and can directly receive the processed dry and crushed samples, reducing the loss and contamination of samples during the transfer process. The sampling component is installed at one end of the top of the vehicle body, and the drying and crushing component and the screening component are respectively fixed on the top of the support frame and the top of the support table, forming a linear process from sampling to processing and then to screening.

Finally, the pulverized soil sample falls directly onto the first screen 606 of the screening component 6. The vibration motor 603 makes the bottom support 602 vibrate to help the soil sample to be screened through the first screen 606 and the second screen 607 in the screen frame 605. The aperture of the first screen 606 is larger than that of the second screen 607. The larger particles are intercepted by the first screen 606 and discharged from the first row of debris plates 608. The smaller particles pass through the second screen 607 and enter the bottom support 602 and are discharged through the second row of debris plates 610. The particles that meet the requirements remain on the second screen 607 and are sent to the sample barrel 7 through the sample unloading plate 609. After screening, the mineral-bound organic carbon separation sample that meets the requirements falls directly into the sample barrel 7, and the operator can conduct further analysis and research thereafter.
