Description

Technical Field

[0001] The present invention relates to the technical field of soil detection, and in particular to a soil organic matter detection device and a detection method. Background Art

[0002] The soil organic matter detection device is an instrument used to detect the content of organic matter in the soil. It can quickly and accurately measure the mass fraction of organic matter in the soil and provide a scientific basis for agricultural production.

[0003] In the prior art, when testing soil for organic matter, workers usually collect soil and transport it to the laboratory for testing. It is difficult to test soil organic matter while taking soil, which increases the transportation and pretreatment time of soil, resulting in a slow testing process, making it difficult for workers to obtain soil fertility information in a timely manner. In addition, some equipment is difficult to transport soil at the same time when testing soil for organic matter, and its practicality is relatively simple. In the prior art, soil usually needs to be ground and mixed after taking soil, and grinding and mixing may introduce new changes, which makes it difficult for the testing process to more truly reflect the natural state of the soil.

[0004] In addition: after testing untreated soil, the prior art finds it difficult to transport, grind and mix the soil, which reduces the uniformity of the soil and increases the matrix effect and spectral interference of later testing. In addition, during the grinding process, some volatile substances may escape from the soil, and the prior art finds it difficult to monitor the gas composition in real time and evaluate the loss of the substance, thereby making it difficult to ensure the integrity of the soil. After grinding the soil, the prior art finds it difficult to perform layered testing on the soil, which reduces the reliability of the test data.

[0005] Finally: Existing technologies make it difficult to integrate soil organic matter data from different processing stages, making it difficult for workers to fully understand the dynamic changes in soil organic matter from its original state to after grinding and mixing, and thus difficult to provide a comprehensive perspective on soil health.

[0048] First, when using this device, first place the device in the working area, and then connect the device to an external power source to provide the device with the power required for operation;

[0049] Second, the staff moves the cart 1 to the area where soil organic matter detection is required, and then starts the motor in the transmission part 2, so that the motor in the transmission part 2 drives the gear set in the transmission part 2 to rotate, the left end gear of the gear set in the transmission part 2 drives the sleeve 31 to rotate, and the sleeve 31 drives the drill bit 4 to rotate, and then starts the cylinder in the transmission part 2, the cylinder in the transmission part 2 drives the mounting rod in the transmission part 2 to move downward, the mounting rod in the transmission part 2 drives the gear box in the transmission part 2 to move downward, and the gear box in the transmission part 2 drives the sleeve 31 and the drill bit 4 to move downward through the gear set, so that the soil is drilled by the rotation and downward movement of the drill bit 4. During the drilling process, the light emitted by the optical fiber probe 35 is irradiated to the soil directly below through the slide groove of the drill bit 4. When the incident light reaches the soil surface, a part of it is absorbed by the soil, and a part of it is diffusely reflected and received by the optical fiber probe 35 and recorded in the first spectrometer 33, so that the organic matter of the soil is detected while drilling the soil, reducing the transportation and pretreatment time of the soil, speeding up the detection process, and enabling the staff to obtain soil fertility information in a timely manner;

[0050] Third, when the drill bit 4 is drilling the soil, the soil is transported from bottom to top through the spiral rod at the top of the drill bit 4 to the sleeve 31, and then transported to the bellows 36 through the sleeve 31, so that the soil in the bellows 36 is gradually accumulated, and then the soil is gradually transported to the test tube 56, thereby increasing the practicality of soil drilling detection. During the use of the bellows 36, the limit rope 37 is used to prevent the bellows 36 from expanding, which makes it difficult to transport the soil.

[0057] After the soil is transported to the test tube 56, the four groups of electromagnetic blocks in the ten groups of arc-shaped slide grooves 54 are driven to work step by step through the external current output device, so that each group of first protrusions 53 slides in the corresponding arc-shaped slide grooves 54 under the magnetic influence of the four groups of electromagnetic blocks, so that the ten groups of first protrusions 53 drive the ten groups of opening and closing plates 52 to move relatively on the top of the fixed plate 51, so that the distance between the ten groups of opening and closing plates 52 is gradually shortened, and then the ten groups of opening and closing plates 52 are closed to prevent the soil from falling off during the detection process. When the soil in the test tube 56 needs to be tested, the staff inserts the four groups of plug blocks 510 into the four groups of empty slots 58, and then starts the light source 59, so that the laser beam of a specific wavelength is irradiated on the soil. The wavelength is selected to be able to effectively excite the specific fluorescence spectrum of the organic pollutant molecules in the soil, and then through The second spectrometer 513 analyzes the collected fluorescence spectrum, and then the second spectrometer 513 performs qualitative and quantitative analysis according to the wavelength and intensity of the fluorescence, so as to identify the organic matter in the soil, and obtain the untreated soil organic matter test results, which more truly reflects the natural state of the soil.
