[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Figure 1 is a schematic diagram of the structure of the mobile soil sample processing device provided by the present invention, such as Figure 1 As shown, the device comprises: a multi-rod parallel spiral sampling device 1, a multi-stage vibration screening device 3 composed of a vibration motor 2, screens 5 with different apertures, namely a first screen, a second screen and a third screen, and a movable partition 6 for isolating each screen, wherein a V-shaped funnel 4 is arranged under each screen; A mobile crawler device consisting of a mobile crawler 7, a crawler support structure 12 and a guide rail driving wheel 11, wherein the guide rail driving wheel 11 is used to drive the mobile crawler 7 to move, and a plurality of sample collecting grooves 8 are arranged in the mobile crawler 7; and a sample processing device consisting of a surface leveling device 9 and a surface compacting roller 10; the device also includes: a sample cleaning roller 13, an image recognition device 15 and a spectrum detection device 14; The multi-rod parallel spiral sampling device 1 is arranged above the multi-stage vibration screening device 3, and the multi-rod parallel spiral sampling device 1 is used to screen the soil sample to the area of ​​the first screen; the multi-stage vibration screening device 3 is arranged obliquely relative to the ground, and the multi-stage vibration screening device 3 is arranged above the mobile crawler device; The multi-stage vibrating screening device 3 comprises a vibrating motor 2, a first screen, a second screen and a third screen whose screen apertures increase from top to bottom, and a movable partition 6 for isolating each screen; More specifically, a first sample collecting slot, a second sample collecting slot and a third sample collecting slot are arranged on the mobile crawler of the mobile crawler device; the first sample collecting slot is used to collect soil samples of a first particle size sieved from a first sieve, the second sample collecting slot is used to collect soil samples of a second particle size sieved from a second sieve, and the third sample collecting slot is used to collect soil samples of a third particle size sieved from a third sieve; In the present invention, the sample slot on the moving crawler is hollowed out at the top and bottom. When the sample is collected and leveled and compacted, a support structure is designed at the bottom of the sample slot. After the sample is leveled, compacted and subsequently spectrally detected, it needs to be driven by the crawler to rotate back to the other end. Before the next sample collection cycle, there is no support structure under the crawler in front of the multi-stage vibration screening equipment, and a structure with a rolling wheel connected to the soft spring terminal is designed above. When the sample passes by, the rolling wheel enters the sample slot under pressure to eject the sample prepared in the previous sample slot, and then the roller slides out of the sample slot during the translation of the guide rail, ready to enter and clear the sample in the next sample slot.

[0025] The image recognition device 15 is used to detect the filling completion status of the first sample collection slot, the second sample collection slot and the third sample collection slot, and transmit the filling completion status to the main control device; The main control device is used to control the mobile crawler device to rotate when the filling completion status of the first sample collection trough, the second sample collection trough and the third sample collection trough are all filled, and control the sample processing device to compact the soil samples in the first sample collection trough, the second sample collection trough and the third sample collection trough; The spectrum detection device 14 is used to perform spectrum detection on soil samples of different particle sizes to obtain characteristic spectra of soil samples of each particle size. The main control device determines the soil composition information of the soil sample based on the characteristic spectra of the soil samples of each particle size.

[0026] Figure 2 This is a top view of the multi-rod parallel spiral injection device in this application, such as Figure 2As shown, the multi-rod parallel spiral sampling device 1 uses multiple spiral sampling rods installed side by side, and there are certain gaps between the spiral sampling rods, which can ensure that small-size soil particles fall into the multi-stage vibration screening device through the gaps. After the soil sample is transferred to the multi-rod parallel spiral sampling device by manual or automatic sampling equipment, the parallel screws transport the soil sample along the radial direction of the screws by rotation. During the transportation process, small particles of soil automatically fall into the multi-stage vibration screening device through the gaps between the screws, while large particles of stone seeds or impurities cannot pass through the gaps between the screws. They move to the far end of the screws and automatically fall under the push of the rotating threads of the screws. The multi-rod parallel spiral sampling device realizes continuous sampling and updating of soil samples and removal of impurities without manual operation.

[0027] The automated sampling and impurity removal process significantly improves the efficiency of soil sample processing and reduces the need for manual operations. Through precise particle separation, the soil samples entering the subsequent processing process are ensured to have higher quality and consistency, thereby improving the accuracy of subsequent spectral detection.

[0028] More specifically, in the present application, a multi-stage vibration screening device is used to sort the particle size of soil samples collected by a multi-rod parallel spiral sampling device. Figure 3 A schematic diagram of a multi-stage vibrating screening device screen provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the multi-stage vibrating screening equipment is divided into three different areas, each area is equipped with a screen 5 with different apertures, and the different areas are separated by a movable partition 6, and the movable partition 6 can specifically be an electrically controllable flap.

[0029] The screen in the present invention presents a certain inclination angle as a whole, and the upper end is a small-aperture screen and the lower end is a large-aperture screen. The collected soil sample first falls into the small-aperture screen at the upper end of the screening device, the partition is in an upright blocking state, and the vibration motor works, so that the small-size particles in the soil sample pass through the screen and fall into the corresponding sample collection slot; after a certain period of time, the partition of the first area opens, and the soil sample that has not passed through the screen of the first area flows to the second area under the joint action of the vibration motor and the inclination of the screening device. The partition of this area is also initially in a blocking state, and the sample is screened out of the second particle size in the second area under the action of vibration; similarly, the soil sample of the third particle size is screened out in the third area. After the screening is completed, the partition of the third area is opened to allow the remaining soil samples to slide out of the screening device under the action of vibration, and the samples on the screen of the screening device are emptied, and then the partitions of the three areas are folded. Through the above device, automatic grading and screening of soil samples and automatic cleaning of the device are realized.

[0030] For example, the multi-stage vibration screening equipment includes three screens, namely the first screen, the second screen and the third screen, whose apertures increase from top to bottom to achieve the separation of soil samples with different particle sizes. In order to isolate each screen, the equipment is equipped with three movable partitions, namely: the first movable partition: arranged between the first screen and the second screen. The second movable partition: arranged between the second screen and the third screen. The third movable partition: arranged at the end of the third screen.

[0031] A V-shaped funnel is arranged under each sieve, and they correspond to the corresponding sample collecting slots respectively. The first V-shaped funnel is located under the first sieve, and its opening size is consistent with the first sample collecting slot and directly corresponds to the first sample collecting slot.

[0032] The second V-shaped funnel is located below the second screen, and the opening size thereof is consistent with the second sample collecting slot and directly corresponds to the second sample collecting slot.

[0033] The third V-shaped funnel is located below the third screen, and the opening size thereof is consistent with the third sample collecting slot and directly corresponds to the third sample collecting slot.

[0034] The soil sample is fed into the first screen area of ​​the multi-stage vibration screening device through a multi-rod parallel spiral feeding device. Under the action of the vibration motor, the soil sample passes through screens of different apertures to achieve particle size classification.

[0035] Soil samples of different particle sizes fall into the sample collection slots on the mobile crawler device through the corresponding V-shaped funnels, namely the first sample collection slot, the second sample collection slot and the third sample collection slot. The movable partition can be adjusted as needed to control the flow of soil samples between different sieves to ensure that each sample collection slot can collect soil samples of corresponding particle sizes.

[0036] In the present invention, accurate screening of soil samples is achieved through the cooperation of sieves with different apertures and movable partitions, ensuring the effective separation of soil samples with different particle sizes. The design of the V-shaped funnel ensures that the soil samples can flow smoothly into the corresponding sample collection slot, improving the efficiency and accuracy of sample collection. The design of the movable partition provides operational flexibility, and the screening process can be adjusted according to actual needs to adapt to different soil sample characteristics. The entire screening process is automatically carried out under the drive of the vibration motor, without the need for manual intervention, thereby improving the convenience and safety of operation.

[0037] In the present invention, the image recognition device uses a visible light camera to observe the sample collection tank in real time to monitor the filling status of the soil sample in the sample tank. Through the built-in image recognition algorithm, it is automatically identified whether the sample volume in the sample tank has reached a predetermined full filling state.

[0038] If the sample slot is completely filled, the image recognition device sends this information to the master control device, and the master control device stops adding samples to the sample slot.

[0039] If the sample slot is not completely filled, the image recognition device sends this information and the location of the missing sample slot to the main control device, requesting additional soil samples.

[0040] The main control device controls the multi-rod parallel spiral sampling device to continue to obtain soil samples based on the information provided by the image recognition device, and accurately transfers the supplementary soil samples to the upper screen of the corresponding sample-deficient slot through the partition baffle control. The main control device starts the vibration motor to help the supplementary soil samples fall through the screen into the corresponding sample collection slot until the sample slot is completely filled.

[0041] Optionally, the surface leveling device is provided with a V-wedge-shaped scraper for scraping off excess soil samples collected in each sample slot during the movement of the soil sample along the moving crawler, so as to ensure that the scraped excess soil will not be mixed into the next sample collection slot; The surface compacting roller is used to compact the soil sample when the soil sample moves along the moving track.

[0042] In the present invention, the surface leveling device is provided with a V-wedge scraper to scrape off excess samples collected in the sample trough during the movement of the soil sample. At the same time, a cylindrical surface compacting roller is provided at the back of the surface leveling device. The roller compacts the soil sample in the sample trough during the passage of the sample. The compacted sample continues to move backward for use in different forms of spectral detection.

[0043] At the same time, the shape of the wedge-shaped scraper is designed to allow excess soil to slide off the sides instead of scraping the soil to the next location as the scraper moves, causing sample confusion.

[0044] The sample trough is moved by the moving tracks, and the surface leveling device and surface compacting roller move accordingly. The tip of the surface leveling device first contacts the soil sample in the sample trough, and scrapes off the excess soil sample in the sample trough during the forward movement, making the sample surface flat and preparing for the compaction operation. At the same time, the excess soil sample in the sample trough is removed from the side of the surface leveling device, so that it falls into the field through the gaps in the moving tracks to avoid sample accumulation and confusion with subsequent samples.

[0045] The front end of the surface compaction roller device is a roller structure, which is in close contact with the surface of the moving track. After the sample is leveled, the roller compacts the sample in the sample slot under the action of the spring. The rotation of the roller ensures that the compaction roller can pass through the sample groove smoothly, so that the sample in the sample slot becomes an ideal sample suitable for spectral detection after compaction.

[0046] In the present invention, the quality of the soil sample is improved through leveling and compacting operations, making it more suitable for spectral detection.

[0047] In the present invention, the spectrum detection device performs spectrum detection on soil samples of different particle sizes to obtain characteristic spectrum data of each particle size sample. Through spectrum detection, the device can capture the spectrum characteristics of soil samples of each particle size, which are crucial for analyzing soil composition.

[0048] In the present invention, laser-induced atomic emission spectroscopy can be performed to determine the contents of different elements in the soil (global indicators).

[0049] Near infrared / infrared absorption spectroscopy can also be used to determine the content of compound molecules in the soil (effective state indicator).

[0050] During the spectrum detection process, the multi-point measurement of a single sample is achieved by controlling the stepping micro-motion of the guide rail. The acquired characteristic spectrum data is smoothed and averaged to improve the stability of the characteristic signal. The processed characteristic spectrum intensity data is brought into the system's built-in model to calculate the content of the target component. The measurement of a point soil sample is completed.

[0051] Optionally, the device further comprises: a sample cleaning roller, wherein the sample cleaning roller is used to clean residual samples on the moving crawler after the soil sample undergoes spectral detection.

[0052] The main function of the sample cleaning roller is to clean the residual soil sample on the moving track after the soil sample has been spectrally detected. By removing the residual sample, the sample cleaning roller ensures that the moving track remains clean and ready for the collection and processing of the next sample.

[0053] More specifically, the present invention can also combine the GPS location information of the mobile positioning system and the soil component content information of the point to establish a one-to-one correspondence between the geographical location and the component information. The combined mobile "measurement while walking" can form a spatial distribution map of the soil component information of the plot, which can also be used to provide prescriptions for soil testing formulas.

[0054] In an optional embodiment, the multi-rod parallel spiral injection device, the mobile crawler device, the multi-stage vibration screening device, the sample processing device, the spectral detection device, the image recognition device, and the main control device are all fixed in a fixed structure, such as the outer shell of a movable vehicle.

[0055] Figure 4 A schematic diagram of the soil sample processing method provided for this application, such as Figure 4 As shown, including: Step 410, the main control device controls the multi-rod parallel spiral sampling device to screen the soil sample into the area of ​​the first screen in the multi-stage vibration screening device; The soil loosening device mounted during the field work of the agricultural machinery plows the soil and breaks up the large pieces of soil in advance to obtain a relatively loose soil sample, and the loosened soil sample can be transmitted to the top of the multi-rod parallel spiral sampling device of the device through a conveyor belt.

[0056] The multi-rod parallel spiral sampling device starts running, and the samples on the conveyor belt automatically fall onto the parallel screws of the multi-rod parallel spiral sampling device. Driven by the rotation of the screws, small particles in the soil sample can pass through the gaps between the screws and fall directly into the first screening area (small particle size) of the screening device, while larger stones, plant residues, etc. are moved to the far end of the sampling screw under the rotation of the screw and finally fall into the farmland.

[0057] Step 420, after the vibration motor in the multi-stage vibration screening device operates for a first preset time, the main control device controls the first movable partition in the multi-stage vibration screening device to open, so that the soil sample that has not passed through the first screen slides to the area where the second screen is located; Step 430, the main control device is used to control the second movable partition in the multi-stage vibration screening device to open after the vibration motor works for a second preset time, so that the soil sample that has not passed through the second screen slides to the area where the third screen is located; Step 440, the main control device is used to control the third movable partition in the multi-stage vibration screening device to open after the vibration motor works for a third preset time, so that the soil sample that has not passed through the third screen slides out of the multi-stage vibration screening device; In the present invention, the multi-stage vibration screening equipment is started, and the movable partitions used for partitioning are all erected in a partitioning state. The filling status of the soil sample in the first sample collection slot is continuously observed by the image recognition device until no sample falls in; then, the first zone partition is driven by the servo to control the first zone partition to rotate 90 degrees and fall down, so that the remaining samples in the first screening zone are transferred to the second sieve area under the action of vibration, and the above actions are repeated until no sample continues to fall into the second sample collection slot; the second zone partition is controlled to flip, and the remaining soil samples are transferred to the third sieve area, and the first partitioning action is repeated to obtain soil samples of corresponding particle sizes to fill the corresponding sample slots. After no new samples fall into the last sample slot, the third partition is controlled to flip, and the remaining soil samples on the sieve are removed under the action of vibration and tilt angle. After the removal is completed, all three partitions are folded up and restored to the original separation state.

[0058] In the present invention, the multi-stage vibration screening equipment does not have any soil sample remaining after the screening process is completed through inclination design and vibration control, and can directly process the next soil sample without human intervention.

[0059] Step 450, the main control device is used to control the mobile crawler device to rotate when the first sample collection trough, the second sample collection trough and the third sample collection trough are all filled, and control the sample processing device to compact the soil samples in the first sample collection trough, the second sample collection trough and the third sample collection trough; The image recognition system is used to determine whether the target samples in the three sample slots are completely filled. If any sample slot is not completely filled, the soil sampling equipment is started again to transport the field soil sample to the multi-rod parallel spiral sampling device until all sample slots are filled with samples.

[0060] Then, the mobile crawler device is started to rotate, thereby driving the sample slot to move. The sample processing device is pressed against the surface of the guide rail under the action of the spring, and the surface of the sample in the sample slot is leveled to facilitate the subsequent compaction operation.

[0061] In step 460, the main control device controls the spectral detection device to perform spectral detection on the soil samples of different particle sizes to obtain characteristic spectra of the soil samples of each particle size. The main control device determines the soil composition information of the soil samples according to the characteristic spectra of the soil samples of each particle size.

[0062] The main control device issues a command to control the spectrum detection device to start working. The spectrum detection device performs spectrum scanning on soil samples of different particle sizes. Through spectrum detection, characteristic spectrum data of each particle size soil sample is obtained. The characteristic spectrum contains unique information about various components in the soil sample. Based on the analysis results, the main control device determines the content and type of each component in the soil sample. This information is crucial for understanding the fertility, pollution level and agricultural suitability of the soil.

[0063] In the present invention, the multi-stage vibrating screening device provides three relatively uniform independent soil samples of different particle sizes. These samples are very important in spectral detection because they allow soils of different particle sizes to be analyzed separately.

[0064] In soil composition, the proportion of soil mechanical composition in the same plot is usually relatively fixed. This means that the proportion of soil particles of different particle sizes in the overall soil is certain. The proportion of the content of soil components in particles of different particle sizes is also relatively stable, that is, each particle size of soil has a certain weight (0-100%).

[0065] In practical applications, only 1-2 typical soil samples can be taken for laboratory analysis for soil in an area. These analyses are used to determine the distribution of target components in samples of different particle sizes, that is, the weight of different particle sizes. Combined with the mobile soil sample rapid spectral detection technology, the characteristic spectra of soil samples of different particle sizes can be obtained. The content of the target under different particle sizes is calculated using the built-in model. The content of the target under different particle sizes is multiplied by the weight of each particle size to obtain the total content of the target in the sample.

[0066] For example: In a sample, the three particle sizes account for P1, P2 and P3 respectively, the sum of P1, P2 and P3 is 100%, and the target content obtained by the three particle sizes is C1, C2 and C3 respectively. Then the actual content of the target in the sample is C, which can be calculated by the following formula: In the present invention, a multi-rod parallel spiral sampling device is located above the multi-stage vibration screening device and is responsible for sending soil samples into the screening process. The multi-stage vibration screening device is tilted relative to the ground to facilitate the classification of soil samples through sieves of different apertures under the action of gravity. The device is provided with a first sieve, a second sieve and a third sieve with gradually increasing apertures from top to bottom, and a movable partition for isolating each sieve to ensure that the soil samples are classified according to particle size. The mobile crawler device is located below the multi-stage vibration screening device, and is provided with a first sample collection slot, a second sample collection slot and a third sample collection slot corresponding to the sieves, respectively, for collecting soil samples of different particle sizes. The image recognition device is used to detect the filling status of each sample collection slot and feed back the information to the main control device. When all the sample collection slots are filled, the main control device controls the mobile crawler device to rotate, so that the sample processing device can compact the soil samples in the collection slots to prepare for spectral detection.
