Description

Technical Field

[0001] This invention relates to the field of topsoil stripping measurement technology, and in particular to a multi-dimensional intelligent topsoil stripping measurement device for power grid engineering. Background Technology

[0002] Topsoil stripping is a technical measure that uses mechanical or manual methods to remove the topsoil from land occupied by construction, storing it for priority use in ecological restoration projects such as land reclamation and farmland improvement. This technology follows the principle of "stripping all that should be stripped and covering all that can be covered," and its implementation scope covers permanent basic farmland, high-quality arable land, and temporary land use. After stripping, the soil needs to be temporarily protected with woven bags and dust nets before being transported to designated storage areas for classified storage. Reuse applications include mine reclamation and high-standard farmland construction. However, in current power grid projects, which often occupy large areas for construction, topsoil stripping should be carried out before construction. However, during the stripping process, it is often impossible to fully test the stripped soil and classify it for storage, resulting in an inability to accurately and fully strip the topsoil for use according to demand.

[0003] Chinese Patent Publication No. CN118937267B discloses a soil organic matter content detection device and its detection method. The method determines the fluctuation difference in the vertical diffusion distribution of organic matter in the soil using spectral data, and then performs multi-scale decomposition on the spectral data to obtain horizontal and vertical spectral characteristic bands. Based on the horizontal spectral characteristic bands, it determines the entropy of organic matter content distribution in the horizontal direction and the distribution information of sampling points to determine the gradient of organic matter content change in different soil blocks. The horizontal and vertical spectral characteristic bands are hierarchically coupled using the content change gradient and fluctuation difference to obtain coupled features. The method also determines the band perturbation during the spectral measurement process and performs spectral compensation on the coupled features based on the band perturbation, thereby realizing the detection of soil organic matter content based on the compensated coupled features. However, the aforementioned soil organic matter content detection device and its detection method have the following problems: It is not possible to determine the subsequent testing process by periodically testing the organic matter content of the topsoil stripped from the soil, so as to classify and store the stripped topsoil and provide timely feedback to the topsoil stripping process for accurate stripping. Summary of the Invention

[0004] To address this, the present invention provides a multi-dimensional intelligent topsoil stripping measurement device for power grid engineering, which overcomes the problem in the prior art that it is impossible to determine the subsequent detection process by periodically detecting the organic matter content of the stripped topsoil, so as to classify and store the stripped topsoil and provide timely feedback to the topsoil stripping process for accurate stripping.

[0005] To achieve the above objectives, the present invention provides a multi-dimensional intelligent topsoil stripping measurement device for power grid engineering, comprising, The organic matter measurement module includes a sampling module and a soil and fertilizer nutrient rapid tester. The sampling module periodically inserts itself into the topsoil after topsoil stripping and transportation to take samples, and then transports the sampled topsoil to the soil and fertilizer nutrient rapid tester to detect the organic matter content. The detection and analysis module determines the first level of soil based on the organic matter content value and the preset content range, and screens out soil that does not meet the preset content range through the channel selection module. The pH value measurement module obtains the pH value of the remaining soil and the preset pH range to determine the second level of soil, and screens out soil that does not meet the preset pH range again. Based on the first deviation value of the organic matter content value from the target organic matter content value and the second deviation value of the pH value from the preset pH median value, the third level of soil and the soil detection tendency group are determined. The topsoil stripping module, connected to the detection and analysis module, is used to strip topsoil layer by layer according to a preset number of stripping times and stripping layer spacing. It determines the first stripping layer spacing of the subsequent topsoil based on a first deviation value, and determines the second stripping layer spacing of the topsoil based on a second deviation value to compensate for the deviation of the previous first stripping layer spacing. Based on the first and second deviation values ​​in the mixed soil detection tendency group, it combines the first moisture content of the soil obtained by the moisture content detection module with the second stripping layer spacing of the topsoil for stripping. The topsoil stripping thickness is then determined based on the difference between the theoretical total amount and the actual total amount of stripped topsoil obtained by the weight measurement module. The channel selection module is used to install the organic matter measurement module, pH value measurement module and moisture content detection module, and connects with the detection and analysis module and the topsoil stripping module. Based on screening, the soil is transported to the corresponding storage location, and the remaining soil is transported to the preset location. The weight measurement module is used to detect the layer spacing of the soil stripped by the topsoil stripping module and to obtain point cloud data by emitting a laser beam to scan the topsoil stripping area. After processing, the point cloud data is used to construct a three-dimensional model of the topsoil stripped to determine the theoretical total amount of topsoil stripped and to weigh the actual total amount of topsoil stripped.

[0006] Furthermore, the channel selection module includes a limiting frame, a fixed channel, a rotating table, a rotating channel, and a storage box; Storage bins, of which several are provided, are used to classify and store soil in response to determining whether it is of the first, second, or third grade. There are two limit frames, each of which includes several storage channels and is connected to several storage boxes to transport soil into the storage boxes. There are two fixed channels, which are respectively set on two limit frames. The two limit frames are connected through the fixed channels to transport the topsoil stripped to the rotating platform. There are two rotating platforms, which are rotatably connected to the middle of two limit frames to drive the rotating channel to rotate and connect with several storage channels on the corresponding limit frames to transport the soil to several storage boxes. The rotating channel is connected to the rotating table at one end and fits into the corresponding limiting frame at the other end. When rotating, it can be connected to the storage channel.

[0007] Furthermore, the sampling module is set on the limiting frame corresponding to the fixed channel for the initial transport of soil, and can realize lifting and translating movements to sample and lay out the soil during the lifting process and switch the sampling and laying out positions during the translating process.

[0008] Furthermore, the soil fertilizer nutrient rapid tester is set below the sampling position to quickly detect the soil organic matter content when the sampling module performs soil sampling.

[0009] Furthermore, the pH measurement module includes an electronic pH meter and a lifting assembly that drives the electronic pH meter to move linearly. The lifting assembly is set on a fixed channel connecting two limit frames, and can drive the electronic pH meter to quickly measure the pH value of the soil during descent, and drive the electronic pH meter to detach from the soil being tested during ascent.

[0010] Furthermore, the moisture content detection module is installed on the storage channel and the corresponding storage box for transporting soil of the third grade (preferably), and is used to measure the volumetric moisture content of the soil.

[0011] Furthermore, it also includes a mixing component installed on the storage tank equipped with a moisture content detection module to fully mix the soil, thereby ensuring the accuracy of the volumetric moisture content of the mixed soil detected by the corresponding moisture content detection module.

[0012] Furthermore, the weight measurement module includes a laser ranging module, a three-dimensional laser scanning module, and a weighing module; The laser ranging module is used to detect the layer spacing of the soil stripped by the topsoil stripping module; The three-dimensional laser scanning module is used to emit a laser beam to scan the topsoil stripping area to obtain point cloud data. After processing, the point cloud data is used to construct a three-dimensional model of the topsoil stripping soil and determine the theoretical total amount of topsoil stripping. The weighing module is used to weigh the soil stripped from the topsoil to obtain the actual total amount of soil.

[0013] Furthermore, the re-determination of topsoil stripping thickness includes determining the preset stripping layer spacing and preset stripping number of times for the topsoil stripping module.

[0014] Furthermore, the limiting frame is provided with a baffle to prevent soil from falling off when the rotating channel rotates.

[0015] Compared with the prior art, the beneficial effect of the multi-dimensional intelligent topsoil stripping measurement device for power grid engineering of the present invention is that it can determine the subsequent detection process by periodically detecting the organic matter content of the topsoil stripping soil, classify and store the stripped topsoil, and promptly feed back to the topsoil stripping to accurately perform topsoil stripping.

[0016] Furthermore, by using multiple preset organic matter content ranges, the stripped topsoil can be periodically tested and transported to different channels in a timely manner to determine the first grade of the soil and carry out different treatments for different topsoil types.

[0017] Furthermore, by conducting targeted pH value tests on a portion of the identified first-level soil, the soil can be further classified into second-level categories, thus reclassifying the soil into multiple levels and applying different treatments to different topsoil types.

[0018] Furthermore, it is possible to determine the third soil grade for selected soil samples based on the first and second soil grades, and to determine the subsequent testing and treatment processes for these soil samples, so as to accurately control the soil classification and enable the recovered topsoil to be specifically improved for different use needs, thereby making full use of the topsoil recovered during the construction of power grid projects and other projects.

[0025] Please see Figure 1 The following is a detailed embodiment of a multi-dimensional intelligent topsoil stripping measurement device used in topsoil stripping and recycling in power grid engineering: A multi-dimensional intelligent topsoil stripping measurement device for power grid engineering includes, The organic matter measurement module includes a sampling module and a soil and fertilizer nutrient rapid tester 11. The sampling module periodically inserts into the topsoil after topsoil stripping and transportation to take samples, and then transports the sampled topsoil to the soil and fertilizer nutrient rapid tester 11 to detect the organic matter content. Please see Figure 2 As shown, the sampling and testing process of the organic matter measurement module is described in detail. The sampling module is set on the limit frame 01 corresponding to the fixed channel 02 of the initial soil transportation. It can realize lifting and translating movements to sample and lay out the soil during the lifting process and switch the sampling and laying out positions during the translating process. The system includes a base frame connected to a limit frame 01, on which two first cylinders 13 are installed to drive the lifting frame 17 to move linearly. A switching plate 15 is slidably connected to the lifting frame 17, and a sampling frame is fixedly connected to the switching plate 15. A linear module 12 is installed on the lifting frame 17 to drive the switching plate 15 to slide. The lifting frame 17 is driven to move linearly by the synchronous lifting and lowering of the two first cylinders 13. The lifting frame 17 drives the sampling frame to insert into the soil for sampling or to lay out the soil during the descent. During the ascent, it is inserted into the soil for sampling and then removed from the soil or reset after the soil is laid out. The sampling frame includes a body 14 and multiple rows of sampling rods 16 installed on the body 14. The multiple rows of sampling rods 16 are inserted into the soil for sampling. The body 14 is also provided with several handles with different force directions for easy hand sampling. The linear module 12 can be a cylinder assembly or a lead screw and lead screw nut assembly, all of which can realize the required movement process under the control of the intelligent module.

[0026] The soil and fertilizer nutrient rapid tester 11 is set below the sampling position to quickly detect the soil organic matter content when the sampling module performs soil sampling. Please see Figure 3 The process for determining the first level is detailed below: The first level of the soil is determined based on the organic matter content value obtained by the organic matter measurement module and a preset content range. Soils that do not conform to the preset content range are screened out using a channel selection module. The preset content range is (2, 4], but different values ​​can be set according to different needs. The target organic matter content value is 3. The detection and analysis module obtains the organic matter content value, compares it with several preset organic matter content ranges, determines the first grade of the soil, and simultaneously determines whether to conduct soil pH testing or determine the first stripping layer distance of the topsoil. Several preset organic matter content ranges are respectively (0, 1], (1, 2], (2, 3], (3, 4], (4, 10], and the deviation value of organic matter content is determined by subtracting the median value of organic matter content from the organic matter content value. The median value of organic matter content is 2.5. When organic matter content value When the value is (0, 1), the first level is determined to be the extreme level, and the excess level is stored directly without testing the next parameter. The topsoil stripping thickness is reduced by adjusting the stripping layer spacing under a fixed number of stripping times, and the test is performed according to the preset test interval. When organic matter content value When (1, 2), the first level is determined to be poor, and the pH value measurement process is initiated, and the topsoil is stripped according to the preset stripping layer spacing. When organic matter content value When (2, 3), the first grade is determined to be good, and the pH value measurement process is started, and the topsoil is stripped according to the preset stripping layer spacing. When organic matter content value When (3, 4), the first grade is determined to be excellent, and the pH value measurement process is started, and the topsoil is stripped according to the preset stripping layer spacing. When organic matter content value When (4, 10), the first level is determined to be super-excellent, and the super-excellent level is directly stored without testing the next parameter. The topsoil stripping layer spacing is increased to increase the topsoil stripping thickness, and testing is performed according to the preset testing interval. Let the stripping layer spacing before regulation be... The adjusted peeling layer spacing is The deviation value of organic matter content is The regulation coefficient is The correlation coefficient is ; ; This is the control coefficient; The regulation coefficient is correlated with the deviation of organic matter content within a certain range; the greater the deviation of organic matter content, the greater the regulation coefficient. ; at this time The value can be 0.2, but different values ​​can be used depending on the different needs of the subsequent recycling of the topsoil.

[0027] Specifically, the process for determining whether to conduct soil pH testing after identifying the first soil grade is explained in detail: The pH measurement module 21 includes a lifting component and an electronic pH meter. The lifting component drives the electronic pH meter to rise and fall to detect the soil pH value. It is set on the fixed channel 02 connecting the two limit frames 01. It can quickly measure the soil pH value during the descent and detach from the soil during the ascent. The detection and analysis module obtains the pH value of the electronic pH meter and determines the pH deviation value. The lifting assembly includes a fixed frame connected to the corresponding fixed channel 02 and a second cylinder installed on the fixed frame to lift and lower the mounting plate on which the electronic pH meter is mounted. When the second cylinder is activated to extend and retract the cylinder rod, the mounting plate can drive the electronic pH meter to insert into the soil for pH value detection and then detach from the soil to reset, waiting for the next detection.

[0028] Please see Figure 4 The process for determining the second and third levels is detailed below: The pH value of the remaining soil is obtained based on the pH value measurement module and the preset pH range, the second soil grade is determined, and soil that does not meet the preset pH range is screened out again; the preset pH range is [0, 1]. In response to soil pH testing, the pH value of the electronic pH meter is obtained, the pH value is determined to meet the requirements, the second soil grade is determined, and the third soil grade is determined in conjunction with the first soil grade. At the same time, it is determined whether to conduct moisture content testing, determine the second stripping layer distance of the topsoil, or determine the periodic testing interval. By comparing the pH deviation value with the preset pH deviation value, the degree of qualification is determined and the soil is classified as Grade II. The absolute value of the difference between the pH value and the preset pH median value is determined as the pH deviation value; The preset pH value is 6.25, but different preset pH values ​​can be selected according to specific needs. If the pH deviation is ≤0.5, the soil is classified as excellent (second grade). If 0.5 < pH deviation value ≤ 1, then the soil is determined to be of the second grade as good. If 1 < pH deviation value ≤ 1.5, then the soil is determined to be of poor grade 2. If 1.5 < pH deviation, the second soil grade is determined to be the extreme grade. The soil is directly stored in the extreme grade without testing the next parameter. The topsoil stripping thickness is reduced by decreasing the topsoil stripping layer spacing.

[0029] Specifically, the process of confirming the third soil grade and readjusting the stripping layer spacing is described in detail: Based on a first deviation of the organic matter content value from the target organic matter content value and a second deviation of the pH value from a preset pH median value, the soil third grade and soil testing tendency group are determined; the first deviation value is determined by subtracting the target organic matter content value from the organic matter content value, and the second deviation value is determined by the absolute value of the difference between the pH value and the preset pH median value. When the first grade is excellent (i.e., the first deviation value is less than 0 and greater than -1), and the second grade is excellent (i.e., the second deviation value belongs to (0, 0.5)), the soil is determined to be excellent in the third grade. It is directly stored as excellent and the next parameter is not tested. The topsoil stripping layer spacing is increased to increase the topsoil stripping thickness, and the test is carried out according to the preset test interval. When the first grade is excellent (i.e., the first deviation value is less than 0 and greater than -1), and the second grade is good (i.e., the second deviation value belongs to (0.5, 1)), the third grade of soil is determined to be good (i.e., the first deviation value is greater than 0 and less than or equal to 1). The soil is then stored in the good grade and enters the moisture content testing process. The topsoil stripping layer spacing is adjusted, and the testing interval is shortened to test the soil organic matter content. When the first grade is good (i.e., the first deviation value is greater than 0 and less than or equal to 1), and the second grade is excellent (i.e., the second deviation value belongs to (0, 0.5)), the third grade of soil is determined to be good. The soil is then stored in good grade to determine the moisture content testing process. The topsoil stripping layer spacing is adjusted, and the testing interval is shortened to test the soil organic matter content. Soils classified as Grade 3 or better are stored together and then mixed thoroughly. During the mixing process, the volumetric moisture content is tested to determine the degree of acceptance, thereby re-determining the topsoil stripping layer spacing. When the first grade is good and the second grade is good, the third grade of soil is determined to be good. Good grade storage is carried out, the stripping layer spacing is reduced to adjust the topsoil stripping thickness, and the test is carried out according to the preset test interval. When the first grade is poor, or the second grade is poor, the third grade of the soil is determined to be poor. The soil is directly stored as poor grade and the next parameter is not tested. The topsoil stripping layer spacing is reduced to reduce the topsoil stripping thickness, and the test is carried out according to the preset test interval. The adjustment of the peeling layer spacing at this point still follows the relationship described above, as follows: Let the stripping layer spacing before regulation be y, the stripping layer spacing after regulation be y1, the deviation value of organic matter content be x, the regulation coefficient be k1, and the correlation coefficient be k2; ; k1 is the control coefficient; The regulation coefficient is correlated with the deviation of organic matter content within a certain range; the greater the deviation of organic matter content, the greater the regulation coefficient. ; At this point, k2 is set to 0.2. However, different values ​​can be used depending on the different needs of the subsequent recycling and reuse of the topsoil.

[0030] Specifically, the process of testing the volumetric moisture content of soils that have been confirmed as being in the third soil grade and the second testing state is described in detail: A moisture content detection module is used to detect the volumetric moisture content of the soil; including a soil moisture sensor, which is installed on the storage channel 05 for transporting the soil of the third grade (preferred) and on the storage box 06 for loading the soil of the third grade (preferred) to measure the volumetric moisture content of the soil. Based on the determined second soil detection state, the first moisture content of the moisture content detection module is obtained, the moisture content deviation is determined, and its qualification level is judged in order to determine the third stripping layer distance of the topsoil, or, combined with the determined periodic detection interval, the periodic detection interval is re-determined. The detection and analysis module obtains the first moisture content from the soil moisture sensor, determines the moisture content deviation, and judges its qualification level in order to determine the topsoil stripping thickness. The absolute value of the difference between the first moisture content and the preset moisture content is used to determine the moisture content deviation. The moisture content deviation is compared with the preset moisture content deviation to determine its qualification. The preset moisture content is 75%, and the preset moisture content deviation is 15%. Alternatively, different values ​​can be determined for the preset moisture content and preset moisture content deviation based on the required composition of the recycled soil. If the moisture content deviation is less than or equal to the preset moisture content deviation, it is deemed to be qualified; if the moisture content deviation is greater than the preset moisture content deviation, it is deemed to be unqualified. When the moisture content deviation is greater than the preset moisture content deviation, and the moisture content deviation is deemed unqualified, the topsoil is stripped according to the preset stripping layer spacing. If the moisture content deviation is less than or equal to the preset moisture content deviation, it is considered qualified. The topsoil stripping layer spacing is increased to increase the topsoil stripping thickness, and the periodic detection interval is further adjusted to shorten the detection interval for detecting soil organic matter content. The adjustment of the peeling layer spacing still follows the relationship described above, as follows: Let the stripping layer spacing before regulation be y, the stripping layer spacing after regulation be y1, the deviation value of organic matter content be x, the regulation coefficient be k1, and the correlation coefficient be k2; ; k1 is the control coefficient; The regulation coefficient is correlated with the deviation of organic matter content within a certain range; the greater the deviation of organic matter content, the greater the regulation coefficient. ; At this point, k2 is set to 0.2. However, different values ​​can be used depending on the different needs of the subsequent recycling and reuse of the topsoil.

[0031] Specifically, the process of sorting and storing the soil after topsoil stripping and transportation is described in detail: The channel selection module is used to install the organic matter measurement module, pH value measurement module 21 and moisture content detection module, and in response to determining the first, second or third grade of soil, the corresponding topsoil is transported or stored respectively. The channel selection module includes a limiting frame 01, a fixed channel 02, a rotating table 03, a rotating channel 04, and a storage box; The storage tank, which is provided in several units, is used to classify and store soil in response to determining whether it is of the first, second, or third grade. The storage tank can be connected to other storage structures. When the tank is full of soil, soil can be loaded into other storage structures or supplied to other storage structures at fixed intervals to prevent the soil in the storage tank from becoming too full to continue storing. There are two limit frames 01. Each limit frame 01 includes several storage channels 05. Each limit frame 01 is connected to several storage boxes for transporting soil into the storage boxes. There are two fixed channels 02, which are respectively set on two limit frames 01. The two limit frames 01 are connected through the fixed channels 02 to transport the topsoil stripped soil to the rotating platform 03. Two rotating platforms 03 are provided, each rotatably connected to the middle of two limit frames 01, to drive the rotating channel 04 to rotate and connect with several storage channels 05 on the corresponding limit frame 01 to transport soil to several storage boxes; each rotating platform 03 is connected to a first servo motor installed on the corresponding limit frame 01, thereby controlling the rotation direction, rotation speed and opening and closing time of the first servo motor through an intelligent module, and adjusting the rotation direction, rotation angle and speed of the rotating platform 03.

[0032] The rotating channel 04 is connected to the rotating table 03 at one end and is attached to the corresponding limiting frame 01 at the other end. When rotating, it can be connected to the storage channel 05.

[0033] This allows for the initial grading of topsoil after organic matter content testing, followed by a secondary grading after pH testing. Different types of topsoil are stored in different spaces, enabling targeted selection and improvement of different soil types for reuse during topsoil recycling. For example, overly acidic or alkaline soils can be neutralized before use, or soils with low organic matter content can be mixed with soils with high organic matter content to create a better-quality soil for use.

[0034] Specifically, this document details the process of comparing the theoretical total amount obtained through modeling and experiments with the actual total amount obtained through actual measurement after topsoil separation: The weight measurement module is used to detect the layer spacing of the soil stripped by the topsoil stripping module and to scan the topsoil stripping area with a laser beam to obtain point cloud data. After processing, the point cloud data is used to construct a three-dimensional model of the topsoil stripped soil to determine the theoretical total amount of topsoil stripped, and to weigh the stripped soil to determine the actual total amount of soil. The weight measurement module includes a laser ranging module, a three-dimensional laser scanning module, and a weighing module; The laser ranging module detects the layer spacing of the soil stripped by the topsoil stripping module in real time. The three-dimensional laser scanning module emits a laser beam, measures the reflection time or phase delay of the laser from the instrument to the target surface, calculates the distance, and combines it with horizontal or vertical angle data to generate a dense point cloud. After processing, the point cloud data can be used to construct a three-dimensional model of the topsoil stripped soil for accurate calculation of the stripped soil volume. Combined with the laser ranging module, the layer spacing of the topsoil stripped by the topsoil stripping module is detected in real time, and the generated three-dimensional model of the topsoil stripped soil is overlaid in real time to construct a new three-dimensional model of the topsoil stripped soil to determine the theoretical total amount of topsoil stripped. The weighing module weighs the stored soil in real time to determine the actual total amount of soil. The detection and analysis module acquires a three-dimensional model of the topsoil stripped from the soil to determine the theoretical total amount of topsoil stripped from the soil, and acquires soil data weighed by the weighing module to determine the actual total amount of topsoil stripped from the soil. The soil weight is obtained by multiplying the topsoil stripping soil three-dimensional model by the soil density, and the theoretical total amount is determined. By comparing the theoretical total amount with the actual total amount, the degree of qualification of topsoil stripping is determined; If the theoretical total amount ≤ the actual total amount ± the correction coefficient, then the topsoil stripping is deemed qualified; if the theoretical total amount ≤ the actual total amount ± the correction coefficient, then the topsoil stripping is deemed unqualified. Based on the unqualified topsoil stripping, the topsoil stripping thickness is re-determined. Determining the topsoil stripping thickness includes determining the preset stripping layer spacing and the preset stripping number. When the theoretical total amount ≤ the actual total amount ± the correction factor, or when the theoretical total amount < the actual total amount - the correction factor, or when the theoretical total amount > the actual total amount + the correction factor, the preset stripping layer spacing and preset stripping number are redefined to ensure timely understanding of the topsoil stripping situation and to fully correct the accuracy of construction.

[0035] Specifically, the process of the intelligent module acquiring organic matter content, pH value, moisture content, theoretical total and actual total, and adjusting the working status of each module is explained in detail: The intelligent module is connected to the organic matter measurement module, pH value measurement module 21, moisture content detection module, channel selection module and weight measurement module; Obtain the organic matter content value from the organic matter measurement module, compare the organic matter content value with several preset organic matter content ranges, determine the first soil grade, and simultaneously determine the first soil detection state, or determine the first topsoil stripping layer distance. Based on the determined first soil testing state, the pH value of the electronic pH meter is obtained to determine its qualification level, the second soil level is determined, and the third soil level is determined in conjunction with the first soil level. At the same time, the second soil testing state is determined, or the second stripping layer distance of the topsoil is determined, or the periodic testing interval is determined. Based on the determined second soil detection state, the first moisture content of the moisture content detection module is obtained, the moisture content deviation is determined, and its qualification level is judged in order to determine the third stripping layer distance of the topsoil, or, combined with the determined periodic detection interval, the periodic detection interval is re-determined. Obtain the theoretical and actual total amounts, determine the degree of qualification of topsoil stripping, and redetermine the topsoil stripping thickness.

[0036] Specifically, the sampling module is set on the limiting frame 01 corresponding to the fixed channel 02 for initial soil transportation, and can realize lifting and translating movements to sample and lay out the soil during the lifting process and switch the sampling and laying out positions during the translating process.

[0037] Specifically, the soil fertilizer nutrient rapid tester 11 is set below the sampling position to quickly detect the soil organic matter content when the sampling module performs soil sampling.

[0038] Specifically, the pH measurement module 21 includes an electronic pH meter and a lifting assembly that drives the electronic pH meter to move linearly. The lifting assembly is set on a fixed channel 02 that connects two limit frames 01. It can drive the electronic pH meter to quickly measure the pH value of the soil during the descent and drive the electronic pH meter to detach from the soil being tested during the ascent.

[0039] Specifically, the moisture content detection module is installed on the storage channel 05 for transporting soil of the third grade (ideal) and on the corresponding storage box 06, and is used to measure the volumetric moisture content of the soil.

[0040] Specifically, it also includes a mixing component installed on the storage bin 06, which is equipped with a moisture content detection module, to fully mix the soil and ensure the accuracy of the volumetric moisture content of the mixed soil detected by the corresponding moisture content detection module.

[0041] Specifically, the limiting frame 01 is provided with a baffle to prevent soil from falling off when the rotating channel 04 rotates. Specifically, the working process of the topsoil stripping module will be explained in detail: The topsoil stripping module is used to strip topsoil layer by layer. It strips topsoil according to a preset number of stripping operations and a preset stripping layer spacing. The stripping layer spacing can be adjusted by adjusting the penetration depth of the stripping parts to meet the needs of different stripping thicknesses. The preset number of stripping operations and the preset stripping layer spacing can be set according to the topsoil stripping thickness.

[0042] The organic matter measurement module can also measure the content of nutrients such as ammonium nitrogen and available phosphorus.
