[0010] Preferably, the container is composed of a cabinet, partitions and a door. The cabinet is located in the middle of the testing machine. The door is rotatably installed on one side of the cabinet. The partitions are evenly installed inside the cabinet. A door lock is installed between the door and the cabinet.

[0011] Preferably, the first soil testing mechanism consists of a soil tester, a wire, and a probe. The soil tester is installed on the upper side of the testing platform, one end of the wire is installed on one side of the soil tester, and the probe is installed on the other side of the wire. The wire and the probe are placed inside a holding trough on the upper side of the testing platform.

[0012] Preferably, the second soil testing mechanism consists of a rotating support and an X-ray fluorescence analyzer. The upper end of the X-ray fluorescence analyzer is installed in the lower middle of the rotating support, and the bottom end of the rotating support is rotatably installed inside the holding tank on the upper side of the testing platform.

[0014] Preferably, the moving mechanism consists of omnidirectional wheels and movable wheels, with the omnidirectional wheels installed on both sides of the front end of the detection body and the movable wheels installed on both sides of the rear end of the detection body.

[0015] A detection method for a soil testing device in a contaminated environment includes the following steps: S1. Upon arrival at the testing point, fix the soil testing device and adjust its orientation using the casters of the moving mechanism to prevent displacement during the testing process. Take a sampling tool from the holding plate of the holding mechanism and collect an appropriate amount of soil sample from the target contaminated soil area. Place the collected soil sample in the soil placement trough at the front of the testing platform on the upper part of the testing machine for temporary storage. Perform preliminary sample sorting in this area, screening and classifying the samples to distinguish between key testing samples and routine testing samples, laying the foundation for subsequent testing operations; S2. After the preliminary preparation and sample pretreatment are completed, the formal testing stage begins. During the testing process, the opening and closing status of the testing space can be controlled by opening and closing the cover of the testing machine; the testing data generated in each testing stage will be transmitted in real time to the display inside the cover to achieve intuitive presentation of the testing results. This testing operation is divided into two core stages: the first soil testing mechanism testing and the second soil testing mechanism testing. The specific operation process is as follows; S4. The probe and lead wire of the first soil testing institution are normally stored in the storage tank of the testing platform. Before testing, they are taken out of the storage tank, and the probe of the first soil testing institution is inserted into the pre-treated soil sample, ensuring full contact between the probe and the sample. The soil tester of the first soil testing institution establishes a signal transmission path with the probe through the lead wire. After the probe senses the physicochemical properties of the soil, such as conductivity, pH, and salinity, it transmits the signal to the soil tester through the lead wire. After the soil tester completes signal conversion and analysis, it generates test data and transmits it to the control processor. The testing personnel can view the test results in real time through the display inside the cover plate, and can also issue operation commands through the control buttons on the control processor to trigger the loudspeaker to announce the test status information; S5, the first soil testing institution tests... After the initial test, the heavy metal testing of the second soil testing unit is carried out. The second soil testing unit consists of a rotating support and an X-ray fluorescence analyzer. Normally, it is stored in the holding slot of the testing platform. Before testing, the rotating support is taken out and adjusted to rotate the X-ray fluorescence analyzer to the preset testing angle. The container containing the sample to be tested is placed in the contour groove of the holding platform to achieve precise positioning of the sample container and avoid detection offset. The height of the holding platform is adjusted by the telescopic rod so that the X-ray fluorescence analyzer is aligned with the sample to be tested. The X-ray fluorescence analyzer is started, and the heavy metal elements in the soil sample are excited to produce characteristic fluorescence using the principle of X-ray fluorescence spectroscopy. Then, the types and contents of heavy metals in the soil are analyzed and determined. The data generated by the test is transmitted to the control processor in real time and displayed on the display inside the cover plate.S6. The test data generated by the first and second soil testing institutions are received and analyzed by the control processor at the front end of the testing platform. The storage on the upper side of the control processor synchronously stores all test data in real time, ensuring data traceability, preventing data loss, and facilitating subsequent data processing and analysis. If remote data transmission is required, the wireless transceiver module on the control processor side can be activated to complete the wireless synchronous transmission of test data with external terminals, eliminating the need for manual copying on-site and improving the convenience and timeliness of data transmission. S7. After data storage is completed, the testing personnel manually record key test data based on the test results displayed on the internal monitor of the cover plate. If a printing device is provided, the test data can be printed and archived through relevant operations to ensure the completeness of the test data record and provide a reliable basis for subsequent analysis. S8. After testing and data recording are completed, the probe and wires of the first soil testing institution are tidied up and placed back into the storage tank of the testing platform to avoid wire tangling and probe wear. The rotating bracket of the second soil testing institution is adjusted to return the X-ray fluorescence analyzer to its initial position and placed into the storage tank of the testing platform. The tested soil samples and waste are then classified and sorted. First, place the samples to be retained into the sample box and put it into the corresponding compartment of the storage cabinet in the middle of the testing unit. Dispose of waste properly according to regulations; indiscriminate disposal is strictly prohibited. Clean the auxiliary tools and containers on the storage plate of the storage mechanism. Fold the folding triangular support frame of the storage mechanism to reduce the space occupied by the device. Close the cover of the testing unit and lock it with the mechanical lock. Close the storage cabinet door and lock it with the door lock. Thoroughly check that all components of the device are in their proper positions and that the power supply is off. After confirming that everything is correct, push the handrail at the rear of the testing unit and use the casters and wheels of the moving mechanism to transfer the soil testing device to the designated storage location, completing this testing process.

[0016] The beneficial effects of the above technical solution are as follows: 1. This solution, through the first and second soil testing mechanisms, enables the soil testing device to possess the core advantage of on-site testing, eliminating the need for complex laboratory equipment. It is convenient to operate and highly practical, capable of quickly responding to on-site needs for soil testing in polluted environments. Simultaneously, it allows for simultaneous testing and sampling, effectively improving testing results. 2. In this solution, the holding mechanism achieves the switching between storage and use of the holding plate through the folding and unfolding of the folding triangular support frame. When the holding plate is needed, the folding triangular support frame is unfolded, and its stable triangular structure provides solid support for the holding plate. The holding plate can be used to place auxiliary tools, sample containers, and other items required during the testing process, making them easily accessible to testing personnel. When the testing is completed or the holding plate is no longer needed, the folding triangular support frame is folded away, significantly reducing the space occupied by the device and facilitating its storage and movement. 3. In this solution, the rotating bracket of the second soil testing mechanism can drive the X-ray fluorescence analyzer during use. The X-ray fluorescence analyzer is adjustable by rotating the support during testing to align it with the contaminated soil sample. Utilizing X-ray fluorescence spectroscopy, the analyzer excites heavy metals in the soil sample to produce characteristic fluorescence, thus analyzing the types and amounts of heavy metals present. When not in use, the support can be rotated to a suitable angle and placed in the storage compartment. 4. In this solution, the soil testing instrument establishes a signal transmission path with the probe via wires during use. The probe is inserted into the contaminated soil sample, sensing the soil's conductivity, pH, and salinity, transmitting the sensed signals to the soil testing instrument via wires. The instrument converts and analyzes the signals to obtain corresponding test data, which is then transmitted to the control processor. When not in use, the wires and probe can be stored in the storage compartment on the top of the testing platform to prevent wire tangling and probe wear, extending component lifespan.

Detailed Implementation

[0019] The foregoing and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the embodiments with reference to Figures 1 to 5. The structural contents mentioned in the following embodiments are all based on the accompanying drawings.

[0020] Example 1: This example provides a soil testing device for contaminated environments, as shown in Figures 1-5. The device includes a soil testing device 1; the soil testing device 1 consists of a testing body 2 and a cover plate 11. One end of the cover plate 11 is rotatably mounted on the upper side of the testing body 2. Mechanical locks are installed on the upper side of the testing body 2 and the front end of the cover plate 11. A display 24 is installed inside the cover plate 11. A power supply mechanism 4 is installed below the testing body 2. A moving mechanism 6 is installed at the bottom of the testing body 2. A handrail 12 is installed at the rear end of the testing body 2. A storage cabinet 3 is installed in the middle position. A storage mechanism 10 is installed on one side of the testing body 2. A testing platform 13 is installed on the upper end of the testing body 2. A first soil testing mechanism 25 is installed on one side of the upper end of the testing platform 13. A second soil testing mechanism 32 is installed on the other side of the upper end of the testing platform 13. Storage platforms 29 are installed on both sides of the first soil testing mechanism 25 and the second soil testing mechanism 32 on the upper side of the testing platform 13. A control processor 20 is installed on one side of the front end of the testing platform 13. A soil placement trough 23 to be tested is installed on the other side of the front end of the testing platform 13.

[0021] In Example 2, based on Example 1, as shown in Figure 4, a contoured groove 30 is provided on the upper side of the holding platform 29. A telescopic rod 31 is installed at the bottom of the holding platform 29 located below the second soil testing mechanism 32. The bottom end of the telescopic rod 31 is installed inside the testing table 13. The contoured groove 30 on the upper side of the holding platform 29 can achieve precise positioning of the sample container or testing element, ensuring the stability of the sample or element during the testing process and avoiding the impact of placement offset on the testing accuracy. The telescopic rod 31 located below the second soil testing mechanism 32 realizes the height adjustment of the holding platform 29 through telescopic drive, thereby driving the test sample to contact the second soil testing mechanism 32, allowing the X-ray fluorescence analyzer 34 to better align with the test sample and ensure the accuracy of heavy metal detection data.

[0022] In Example 3, based on Example 1, as shown in Figures 2 and 4, a storage unit 19 is installed on the upper side of the control processor 20. Control buttons 35 are installed on one side of the storage unit 19 on the upper side of the control processor 20. A speaker 21 and a wireless transceiver module 22 are installed side-by-side on the other side of the control processor 20. When in use, the control processor 20 receives test data transmitted from the first soil testing institution 25 and the second soil testing institution 32, analyzes and processes the data, and then sends it to the display 24 for display. Simultaneously, based on the operation commands input by the testing personnel via the control buttons 35, the storage unit 19 can store all test data generated during the testing process in real time, facilitating subsequent data tracing, organization, and analysis, and preventing data loss. The speaker 21 can issue voice prompts when testing is completed, equipment malfunctions, or a preset testing threshold is reached, promptly reminding the testing personnel to perform corresponding operations. The wireless transceiver module 22 enables wireless transmission of test data to external terminals, facilitating remote data synchronization, data sharing, and subsequent analysis by the testing personnel, eliminating the need for manual data copying on-site, improving the convenience and timeliness of data transmission. The collaborative operation of multiple components significantly enhances the intelligence of the device and reduces the intensity of manual operation.

[0023] Example 4, based on Example 1, as shown in Figures 1 and 2, the holding mechanism 10 consists of a holding plate 14 and a folding triangular support frame 15. The holding plate 14 is installed on one side of the folding triangular support frame 15, and the folding triangular support frame 15 is installed on the other side of the testing body 2. The holding mechanism 10 realizes the switching between storing and using the holding plate 14 by folding and unfolding the folding triangular support frame 15. When the holding plate 14 needs to be used, the folding triangular support frame 15 is unfolded, and its stable triangular structure can provide a firm support for the holding plate 14. The holding plate 14 can be used to place auxiliary tools, sample containers and other items required during the testing process, which are convenient for testing personnel to use at will. When the testing is completed or the holding plate 14 is not needed, the folding triangular support frame 15 is folded up, which can greatly reduce the space occupied by the device and facilitate the storage and movement of the device.

[0024] Example 5, based on Example 1, as shown in Figures 2 and 4, the storage cabinet 3 consists of a box body 18, partitions 16, and a door 17. The box body 18 is located in the middle of the testing machine body 2. The door 17 is rotatably installed on one side of the box body 18. The partitions 16 are evenly installed inside the box body 18. A door lock is installed between the door 17 and the box body 18. The storage cabinet 3 opens and closes the internal space of the box body 18 by rotating the door 17. The partitions 16 evenly installed inside the box body 18 divide the internal space into multiple independent areas, which can realize the classified storage of testing tools, consumables, sample boxes, and other items, avoiding the inconvenience of retrieval due to mixed items. The door lock between the door 17 and the box body 18 can lock the door 17 when closed, preventing the internal items from falling out during the movement of the device, and at the same time preventing external pollutants from entering the box body 18 and contaminating the internal stored items.

[0025] Example 6, based on Example 1, as shown in Figures 2 and 3, the first soil testing mechanism 25 consists of a soil tester 26, a wire 27, and a probe 28. The soil tester 26 is installed on the upper side of the testing platform 13. One end of the wire 27 is installed on one side of the soil tester 26, and the probe 28 is installed on the other side of the wire 27. The wire 27 and the probe 28 are placed inside the storage tank on the upper side of the testing platform 13. When in use, the soil tester 26 establishes a signal transmission path with the probe 28 through the wire 27. During testing, the probe 28 is inserted into the contaminated soil sample. The probe 28 can sense the physical and chemical properties of the soil, such as conductivity, pH, and salinity, and transmit the sensed signal to the soil tester 26 through the wire 27. The soil tester 26 converts and analyzes the signal to obtain the corresponding test data, and then transmits the data to the control processor 20. When not in use, the wire 27 and the probe 28 can be stored in the storage tank on the upper side of the testing platform 13 to avoid the wire 27 from getting tangled and the probe 28 from wearing out, thus extending the service life of the components.

[0026] Example 7, based on Example 1, as shown in Figures 2 and 4, the second soil testing mechanism 32 consists of a rotating support 33 and an X-ray fluorescence analyzer 34. The upper end of the X-ray fluorescence analyzer 34 is installed in the lower middle of the rotating support 33, and the bottom end of the rotating support 33 is rotatably installed inside the holding tank on the upper side of the testing platform 13. When in use, the rotating support 33 can drive the X-ray fluorescence analyzer 34 to rotate and adjust at multiple angles. During testing, the detection angle of the X-ray fluorescence analyzer 34 is adjusted by rotating the support 33 to align it with the contaminated soil sample to be tested. The X-ray fluorescence analyzer 34 uses the principle of X-ray fluorescence spectroscopy to excite the heavy metal elements in the soil sample to produce characteristic fluorescence, thereby analyzing the type and content of heavy metals in the soil. When not in use, the rotating support 33 can be rotated to a suitable angle to accommodate the X-ray fluorescence analyzer 34 in the holding tank.

[0027] Example 8, based on Example 1, as shown in Figure 1, the power supply mechanism 4 consists of a battery 5 and a charging port 7. The battery 5 is installed inside the detection body 2, and the charging port 7 is installed on one side of the battery 5. When in use, the battery 5 serves as the core power supply component, providing a stable power output to all power-requiring components such as the control processor 20, the detection mechanism, the display 24, and the wireless transceiver module 22, ensuring that the device can still operate normally in polluted environments without external power. When the battery 5 is low on power, it can be charged by connecting an external charging device through the charging port 7, ensuring the continuous operation capability of the device.

[0028] Example 9, based on Example 1, as shown in Figure 1, the moving mechanism 6 consists of casters 8 and moving wheels 9. The casters 8 are installed on both sides of the front end of the detection body 2, and the moving wheels 9 are installed on both sides of the rear end of the detection body 2. When in use, the moving mechanism 6 realizes the overall movement of the device through the coordinated rolling of the casters 8 and the moving wheels 9. The casters 8 have a steering function, which can flexibly adjust the movement direction of the device, making it convenient to turn and shuttle in narrow spaces or complex terrains at the pollution site. The moving wheels 9 provide stable rolling support for the device. With the help of the handrail 12, the testing personnel can easily push the device to move between different testing points without the need for other handling equipment.

[0029] A detection method for a soil detection device in a contaminated environment includes the following steps: S1. After arriving at the detection point, fix the soil detection device 1, adjust the orientation of the device using the casters 8 of the moving mechanism 6 to prevent displacement of the device during the detection process, take a sampling tool from the holding plate 14 of the holding mechanism 10, collect an appropriate amount of soil sample from the target contaminated soil area, and temporarily store the collected soil sample in the soil placement trough 23 at the front end of the detection platform 13 on the upper end of the detection body 2. Complete the preliminary sorting of the sample in this area, screen and classify the sample, distinguish between key detection samples and routine detection samples, and lay the foundation for subsequent detection operations; S2. After the preliminary preparation and sample pretreatment are completed, the formal detection stage begins. During the detection process, the opening and closing state of the detection space can be controlled by opening and closing the cover plate 11 of the detection body 2; the detection data generated in each detection stage will be transmitted in real time to the display 24 inside the cover plate 11 to realize the intuitive presentation of the detection results. This detection operation is divided into two core stages: the first soil detection mechanism 25 detection and the second soil detection mechanism 32 detection. The specific operation process is as follows; S4. The probe 28 and wire 27 of the first soil testing device 25 are normally stored in the holding tank of the testing platform 13. Before testing, they are taken out of the holding tank, and the probe 28 of the first soil testing device 25 is inserted into the pre-treated soil sample, ensuring that the probe 28 is in full contact with the sample. The soil tester 26 of the first soil testing device 25 establishes a signal transmission path with the probe 28 through the wire 27. After the probe 28 senses the physical and chemical properties of the soil such as conductivity, pH and salinity, it transmits the signal to the soil tester 26 through the wire 27. After the soil tester 26 completes signal conversion and analysis, it generates test data and transmits it to the control processor 20. The testing personnel can view the test results in real time through the display 24 inside the cover plate 11, or issue operation commands through the control button 35 on the control processor 20 to trigger the announcer 21 to broadcast the test status information; S5, the first soil testing device After the initial test 25 is completed, the heavy metal testing operation of the second soil testing unit 32 is carried out. The second soil testing unit 32 consists of a rotating support 33 and an X-ray fluorescence analyzer 34. Normally, it is stored in the holding slot of the testing platform 13. Before testing, the rotating support 33 is taken out and adjusted to rotate the X-ray fluorescence analyzer 34 to the preset testing angle. The container containing the sample to be tested is placed in the contour groove 30 of the holding platform 29. The contour groove 30 achieves precise positioning of the sample container and avoids detection offset. The height of the holding platform 29 is adjusted by the telescopic rod 31 so that the X-ray fluorescence analyzer 34 is aligned with the sample to be tested. The X-ray fluorescence analyzer 34 is started and the heavy metal elements in the soil sample are excited to produce characteristic fluorescence using the principle of X-ray fluorescence spectroscopy. Then, the types and contents of heavy metals in the soil are analyzed and obtained. The data generated by the test is transmitted to the control processor 20 in real time and displayed through the display 24 inside the cover plate 11.S6. The test data generated by the first soil testing institution 25 and the second soil testing institution 32 are received and analyzed by the control processor 20 at the front end of the testing station 13. The storage 19 on the upper side of the control processor 20 synchronously stores all test data in real time, ensuring data traceability, avoiding data loss, and facilitating subsequent data processing and analysis. If remote data transmission is required, the wireless transceiver module 22 on the side of the control processor 20 can be activated to complete the wireless synchronous transmission of test data with external terminals, eliminating the need for manual copying on-site and improving the convenience and timeliness of data transmission; S7. After data storage is completed, the testing personnel manually record key test data such as soil pH and heavy metal content based on the test results displayed on the internal display 24 of the cover plate 11. If a printing device is provided, the test data can be printed and archived through relevant operations to ensure the completeness of the test data record and provide a reliable basis for subsequent analysis. S8. After the test and data recording are completed, the probe 28 and wire 27 of the first soil testing mechanism 25 are tidied up and placed back into the storage tank of the testing platform 13 to avoid tangling of the wire 27 and wear of the probe 28. The rotating bracket 33 of the second soil testing mechanism 32 is adjusted to rotate the X-ray fluorescence analyzer 34 back to its initial position and place it into the storage tank of the testing platform 13 for storage. The tested soil samples and waste Waste is sorted and organized. Samples that need to be retained are placed into sample boxes and then placed in the corresponding compartment of the storage cabinet 3 in the middle of the testing unit 2. Waste is disposed of properly according to regulations and must not be discarded at will. Auxiliary tools and containers on the storage plate 14 of the storage mechanism 10 are cleaned. The folding triangular support frame 15 of the storage mechanism 10 is folded to reduce the space occupied by the device. The cover 11 of the testing unit 2 is closed and locked with a mechanical lock. The door 17 of the storage cabinet 3 is closed and locked with a door lock. The device's components are fully checked for proper placement and the power supply mechanism 4 is turned off. After confirming that everything is correct, the handrail 12 at the rear of the testing unit 2 is pushed, and the soil testing device 1 is transferred to the designated storage location using the casters 8 and 9 of the moving mechanism 6, completing this testing process.

[0030] Working principle: When in use, the soil testing device 1 controls the opening and closing of the testing space through the opening and closing of the cover plate 11 and the testing body 2. During the testing process, the first soil testing mechanism 25 can perform on-site rapid testing of the soil's conductivity, pH, and salinity, while the second soil testing mechanism 32 focuses on on-site testing of the heavy metal content in the soil. The test data can be transmitted in real time to the display 24 inside the cover plate 11 for intuitive presentation, facilitating immediate access to test results by the testing personnel. Before testing, the soil sample can be temporarily stored and preliminarily prepared through the soil placement trough 23 on the testing platform 13, and can also be processed using related structures. The system allows for on-site screening of soil samples, precisely distinguishing between those requiring intensive testing and routine samples. Selected intensive samples can be directly tested on-site, eliminating the need to bring them all back to the laboratory, effectively shortening the testing cycle and improving efficiency. The power supply mechanism 4 provides stable power support for the entire device. The mobility mechanism 6, in conjunction with the handrail 12, enables flexible movement of the device in contaminated environments, facilitating personnel switching between different testing points. The storage cabinet 3 and storage mechanism 10 can separately classify and store testing tools, auxiliary consumables, and sample waste generated during the testing process, ensuring a clean and orderly testing site. This structural design gives the device the core advantage of on-site testing, eliminating the need for complex laboratory equipment, offering convenient operation and high practicality, and enabling rapid response to on-site needs for contaminated soil testing.

10. A detection method for a detection device for soil in a contaminated environment as described in any one of claims 1-9, characterized in that, Includes the following steps: S1. After arriving at the testing point, fix the soil testing device (1), and adjust the orientation of the device by using the casters (8) of the moving mechanism (6) to avoid displacement of the device during the testing process. Take the sampling tool from the holding plate (14) of the holding mechanism (10), collect an appropriate amount of soil sample in the target contaminated soil area, and place the collected soil sample in the soil placement trough (23) at the front of the testing platform (13) on the upper end of the testing body (2) for temporary storage. Complete the preliminary sorting of the sample in this area, screen and classify the sample, and distinguish between key testing samples and routine testing samples to lay the foundation for subsequent testing operations; S2. After the preliminary preparation and sample pretreatment are completed, the formal testing stage begins. During the testing process, the opening and closing status of the testing space can be controlled by opening and closing the cover plate (11) of the testing machine (2). The testing data generated in each testing stage will be transmitted in real time to the display (24) inside the cover plate (11) to realize the intuitive presentation of the testing results. This testing operation is divided into two core stages: the first soil testing institution (25) testing and the second soil testing institution (32) testing. The specific operation process is as follows: S4, The probe (28) and wire (27) of the first soil testing unit (25) are normally stored in the storage tank of the testing platform (13). Before testing, they are taken out of the storage tank and the probe (28) of the first soil testing unit (25) is inserted into the pre-treated soil sample to ensure that the probe (28) is in full contact with the sample. The soil tester (26) of the first soil testing unit (25) establishes a signal transmission path with the probe (28) through the wire (27). After the probe (28) senses the physical and chemical properties of the soil such as conductivity, pH and salinity, it transmits the signal to the soil tester (26) through the wire (27). After the soil tester (26) completes the signal conversion and analysis, it generates test data and transmits it to the control processor (20). The tester can view the test results in real time through the display (24) inside the cover plate (11), or issue operation commands through the control button (35) on the control processor (20) to trigger the loudspeaker (21) to broadcast the test status information.S5. After the first soil testing institution (25) completes the testing, the second soil testing institution (32) will carry out heavy metal testing. The second soil testing institution (32) consists of a rotating support (33) and an X-ray fluorescence analyzer (34). It is normally stored in the holding slot of the testing platform (13). Before testing, the rotating support (33) is taken out and adjusted to drive the X-ray fluorescence analyzer (34) to rotate to the preset testing angle. The container containing the sample to be tested is placed in the contour groove (30) of the holding platform (29) (the contour groove (30) enables the sample container to be accurately positioned and avoids detection offset). The height of the holding platform (29) is adjusted by the telescopic rod (31) so that the X-ray fluorescence analyzer (34) is aligned with the sample to be tested. The X-ray fluorescence analyzer (34) is started and the characteristic fluorescence of the heavy metal elements in the soil sample is excited by the principle of X-ray fluorescence spectroscopy. Then, the types and contents of heavy metals in the soil are analyzed and obtained. The data generated by the test is transmitted to the control processor (20) in real time and displayed through the display (24) inside the cover plate (11); S6. The test data generated by the first soil testing institution (25) and the second soil testing institution (32) are received and analyzed by the control processor (20) at the front end of the testing station (13). The storage device (19) on the upper side of the control processor (20) synchronously stores all test data in real time, ensuring data traceability, avoiding data loss, and facilitating subsequent data organization and analysis. If remote data transmission is required, the wireless transceiver module (22) on the side of the control processor (20) can be activated to complete the wireless synchronous transmission of test data with external terminals, eliminating the need for manual copying on-site and improving the convenience and timeliness of data transmission; S7, After the data storage is completed, the testing personnel manually record key testing data (such as soil pH value, heavy metal content, etc.) based on the test results displayed on the internal display (24) of the cover plate (11). If a printing device is provided, the test data can be printed and archived through relevant operations to ensure the completeness of the test data record and provide a reliable basis for subsequent analysis. S8. After the test and data recording are completed, the probe (28) and wire (27) of the first soil testing mechanism (25) are tidied up and put back into the storage tank of the testing table (13) to avoid the wire (27) from getting tangled and the probe (28) from getting worn. Adjust the second soil testing mechanism. (32) Rotate the bracket (33) to rotate the X-ray fluorescence analyzer (34) back to the initial position and place it in the storage slot of the detection table (13) for storage. Soil samples and waste after detection are sorted and sorted. Samples that need to be retained are put into sample boxes and placed in the corresponding partition of the storage cabinet (3) in the middle position of the detection body (2). Waste is properly disposed of in accordance with the specifications and is strictly prohibited from being discarded at will. Clean the auxiliary tools and containers on the storage plate (14) of the storage mechanism (10), fold the folding triangular support frame (15) of the storage mechanism (10) to reduce the space occupied by the device, close the cover plate (11) of the detection body (2) and lock it with a mechanical lock.Close the container door (17) of the storage cabinet (3) and lock it with the door lock. Thoroughly check the placement of all components and the power supply status (4). After confirming everything is correct, push the handrail (12) at the rear of the testing unit (2). Using the casters (8) and wheels (9) of the moving mechanism (6), transfer the soil testing device (1) to the designated storage location to complete the testing process.
