Description

Technical Field

[0001] This application relates to the technical field of analytical and detection equipment, and particularly relates to a diffusion and absorption device for soil detection. Background Art

[0002] Soil respiration refers to the process in which plant roots, detritivores, fungi, bacteria, etc. in the soil carry out metabolic activities, consume organic matter and produce carbon dioxide; this process includes three main biological processes: soil microbial respiration, root respiration, and soil animal respiration, as well as a non-biological process, namely the chemical oxidation of carbon-containing minerals. The intensity of soil respiration is often used to measure the total activity of soil microorganisms and is also used as one of the indicators to evaluate soil fertility; more than 90% of the nitrogen in the soil exists in the form of organic matter, and this part of nitrogen plays an important role in the nitrogen nutrition supply of plants. Therefore, studying soil respiration and the organic nitrogen components in the soil has an important role in the research of plant growth and soil fertility.

[0003] Currently, the diffusion method is often used for the research of soil organic nitrogen components and soil respiration. A diffusion and absorption device applied to the diffusion method known to the inventor includes a cavity for containing soil or reaction solution, a beaker, a sealing cover, and a group of guide rods fixed in the cavity for containing soil or reaction solution. The cavity formed by all the guide rods serves as the placement cavity for the beaker, and the upper ends of the guide rods pass through the sealing cover and extend above the sealing cover. However, during the implementation of the above-mentioned prior art solution by the inventor of this application, it is found that due to the guide rods passing through the sealing cover in the existing diffusion and absorption device, the sealing cover cannot be quickly tightened and sealed, and the sealing effect is not good.

[0004] The information disclosed in this background art section is only used to deepen the understanding of the background art of the present disclosure, and should not be regarded as an admission or any form of implication that this information constitutes the prior art known to those skilled in the art.

[0022] In order to better understand the technical solution of the present application, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0023] In the description of the present application, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", "clockwise", "counterclockwise", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application. And the "connection" and "coupling" involved in the present application, unless otherwise specified, both include direct and indirect connections (couplings).

[0024] The components, structures, and mechanisms involved in the following embodiments, unless otherwise specified, are all conventional commercially available products.

[0025] The embodiment of the present application provides a diffusion absorption device for soil detection, which solves the technical problems of slow sealing speed and poor sealing effect of the existing diffusion absorption device. It realizes rapid sealing through a bracket that is designed separately from the sealing cover, and has a good sealing effect and higher experimental accuracy.

[0026] This example discloses a diffusion absorption device for soil detection. Refer to Figures 1 to 3 , including a sealable container for accommodating the soil or reaction solution to be detected, a bracket movably placed in the container, and a culture dish 3 relatively fixed on the bracket; after the soil to be detected, the bracket, and the culture dish 3 are sequentially placed in the container, the container is sealed, and the gas emitted by the soil or reaction solution can react with the solution in the culture dish 3, thereby completing the research on soil organic nitrogen components or soil respiration.

[0027] Refer to Figure 1, the container is a transparent glass bottle. The material of the glass bottle is stable and resistant to strong acids and alkalis, which can ensure the accuracy of the experiment. The container includes a bottle body 1 and a sealing cap 2 that corresponds to and matches the bottle body 1. The sealing cap 2 is in threaded fit with the bottle body 1, can be quickly screwed onto the bottle body 1, and has a good sealing effect.

[0028] See Figure 1 , the bracket is a PVC material part with stable properties and resistant to strong acids and alkalis, which can reduce the influence of experimental equipment on the soil or reaction solution and ensure the accuracy of the experiment. It includes a tray 4 for supporting the culture dish 3 and at least three legs passing through the tray 4. A cylindrical protrusion 5 is provided at the bottom inside the container. The enclosed area at the bottom of the legs corresponds to and matches the protrusion 5, and each leg is tangent to the side of the protrusion 5 respectively, so that the bottom of the bracket can be embedded on the protrusion 5 to stabilize the bracket and prevent it from tilting. The top of the legs passes through the tray 4 and is arranged at the corresponding position above the tray 4. The culture dish 3 is placed in the enclosed area at the top of the legs. The top of the legs has a certain blocking effect on the culture dish 3 to prevent the culture dish 3 from falling off the tray 4. The legs include a long leg 6 and two short legs 7. The horizontal position of the top of the long leg 6 is higher than the horizontal position of the top of the short legs 7, which is convenient for the operator to lift the bracket, so as to facilitate the bracket to be placed into or taken out of the container. The two short legs 7 are provided to facilitate the placement of the culture dish 3 on the tray 4, making the bracket easy to operate and use.

[0029] See Figure 2 , Figure 3 , a plurality of air-permeable holes 8 for ventilation are provided on the tray 4, which is convenient for the gas discharged from the soil or reaction solution to be detected below the culture dish 3 to flow through the tray 4 to the upper part, thus ensuring the accuracy of the experiment. At the position where the legs are correspondingly connected to the tray 4, an expansion band 9 and a bottom support 10 for supporting the tray 4 are provided. The middle part of the expansion band 9 is hollow and protrudes to both sides. The outer diameter of the expansion band 9 is larger than the outer diameter of the other positions of the legs. When the legs pass through the tray 4, the tray 4 squeezes the expansion band 9 to make the expansion band 9 contract. The outward tension of the expansion band 9 makes the expansion band 9 fit tightly with the tray 4, and then the tray 4 is fixedly connected to the legs. The bottom support is arranged below the expansion band 9 to block the downward movement of the tray 4, so that the tray 4 is just at the corresponding position of the expansion band 9, making the bracket easy to install. And the legs are movably passed through the tray 4, making the bracket convenient to carry and store.
