Technical Field
[0001] The utility model relates to the technical field of soil detection, and in particular to a soil organic carbon storage detection device. Background Art
[0002] Soil organic carbon is a collective name for humus, plant and animal residues, and microorganisms formed by microbial action. Carbon in the soil includes inorganic carbon and organic carbon. Soil organic carbon refers to various positively charged carbon-containing organic compounds in the soil. It is an extremely important component of the soil. It is not only closely related to soil fertility, but also has a huge impact on the earth's carbon cycle. It is both a "source" and an important "sink" of greenhouse gases.
[0003] In the process of detecting soil organic carbon content, it is first necessary to sample the soil, then mix the soil with the detection reagent so that the soil is fully dissolved in the detection reagent, and then the dissolved soil liquid is tested. However, soil samples often contain impurities such as sand and stone. These impurities cannot be fully mixed with the detection reagent, which will introduce errors in the subsequent detection process and affect the accuracy. Therefore, the soil samples need to be crushed and screened before testing. At present, these pretreatment steps are completed manually, which brings many inconveniences to the operation, the operation is cumbersome, time-consuming, and greatly reduces the work efficiency. Therefore, how to simplify the operation process and improve the detection efficiency is a problem that the current detection device needs to solve. Utility Model Content

[0015] Compared with the prior art, the utility model has the following beneficial effects:
[0016] 1. The utility model integrates the crushing and screening functions into the organic carbon reserve detection device through an integrated design. The device can complete the pre-processing steps of crushing, storing and screening of soil samples in an automated and mechanized manner, thereby avoiding tedious manual operations, simplifying the operation process, improving the convenience of detection operations, saving time, and improving work efficiency.
[0017] 2. The utility model can crush soil samples through the crushing mechanism, crushing the soil samples into small particles suitable for detection, which is conducive to the dissolution of soil samples in the detection reagent, is easy to use, and can effectively improve the working efficiency of soil organic carbon content detection. During use, the soil sample to be tested needs to be placed in the storage mechanism first, and then the crushing impeller is moved to the appropriate position by controlling the electric push rod to drive the horizontal plate to descend, start the drive motor, drive the crushing impeller to rotate at high speed, crush the soil sample, and prepare for the subsequent detection steps.
[0018] 3. The guide plate and guide groove provide stability and guidance, ensuring that the horizontal plate can move up and down smoothly along the predetermined path under the push of the electric push rod. The matching design of the guide plate and the guide groove ensures that the horizontal plate remains stable during the up and down movement without shaking or deviation from the track, which helps to ensure the accurate alignment of the crushing mechanism and the smooth progress of the crushing process. The guide groove moves along the guide plate, providing a clear path for the movement of the horizontal plate. This design ensures the accuracy of the movement of the horizontal plate, allowing the crushing mechanism to accurately reach the predetermined position for work.
[0019] 4. The storage mechanism is convenient for storing soil samples. It is responsible for temporarily storing the soil samples to be processed, and is convenient for cooperating with the crushing mechanism to crush the soil, and can discharge the crushed soil samples into the screening mechanism. In actual use, the crushing mechanism extends into the storage tank to crush the soil sample. After the crushing is completed, turn the knob to drive the bottom plate to flip to the right, so that the crushed soil sample falls into the discharge funnel, and then falls into the screening mechanism through the discharge funnel for screening.
[0020] 5. The support assembly is used to position and support the storage tank, which can ensure the stability of the storage tank and facilitate the placement of the storage tank, thus improving the convenience of operation. In actual use, insert the slide into the slide slot and push the storage tank inward until the slide hits the magnet block. The magnet block can use its magnetism to adsorb and fix the slide, thereby providing a stable fixing force to prevent the storage tank from accidentally moving during the operation of the equipment and ensure the stability of the storage tank.
[0021] 6. A shielding plate is provided on the upper side of the crushing impeller, and the shielding plate is fixed on the rotating shaft. The diameter of the shielding plate is smaller than the inner diameter of the storage tank. The shielding plate is fixed on the rotating shaft and rotates with the crushing impeller. Since its diameter is smaller than the inner diameter of the storage tank, it will not interfere with other structures inside the storage tank, and can effectively shield and protect. The shielding plate can prevent the splashes or dust generated during the crushing process from spreading to the outside of the storage tank, thereby protecting the safety of the operator and keeping the equipment clean.
[0022] 7. The screening mechanism can screen and filter the crushed soil samples to remove the solid particulate matter contained in the soil samples, so as to conduct more accurate analysis and ensure the accuracy of subsequent testing. When the soil sample falls into the screening tank, it can be screened through the screen, so that the soil powder particles fall into the screening tank, while other larger and insoluble solid particles are retained on the screen.
[0023] 8. The support rods are set through the four corners of the support plate, and the upper baffle is limited and the lower end is fixedly connected to the outer shell, providing stable support for the support plate. A vibration motor is installed on the bottom of the support plate, which generates vibrations. The vibration separates the soil particles on the screen more effectively, which can greatly improve the screening efficiency and ensure the accuracy of the screening. The support spring plays a role of buffering and shock absorption, so that the screening tank can obtain a stable vibration frequency during screening, while reducing the impact on the entire device.
