Description

A comprehensive soil testing device Technical Field

[0001] This utility model relates to the field of soil testing, and in particular to a comprehensive soil testing device. Background Technology

[0002] Current soil testing technologies mainly include laboratory chemical analysis, portable spectrometer detection, and IoT-based remote monitoring systems. Laboratory chemical analysis offers high accuracy but is time-consuming, typically requiring 3-5 days to complete sample analysis. Portable spectrometers enable rapid on-site testing, but limitations in equipment size and cost make it difficult to cover simultaneous measurement of multiple parameters. IoT monitoring systems can achieve long-term data acquisition, but rely on fixed sensor nodes, resulting in insufficient flexibility. In recent years, with the increasing demand for precision agriculture and soil pollution remediation, the market urgently needs testing tools that combine high efficiency, multi-indicator simultaneous testing, and mobile deployment capabilities.

[0003] Existing integrated soil testing devices typically involve continuous sampling at multiple points during soil sample collection. This results in a lack of partitioned design in the sample storage components during the storage and processing of collected soil samples. Consequently, soil samples collected from multiple batches are easily mixed, leading to cross-contamination and making traceability difficult. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a comprehensive soil testing device, which aims to improve the problem that soil samples from multiple locations are easily mixed and cause poor contamination when the existing device is used for soil sample testing.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A comprehensive soil testing device includes a frame, a testing component installed on one side of the frame, a collection component installed on the other side of the frame, and a sampling component disposed in the middle of the frame.

[0007] The collection assembly includes a connecting shell, a collection port fixedly connected to the top of the connecting shell, a sealing cap threadedly connected to the top of the collection port, an installation chamber threadedly connected to the bottom of the connecting shell, a toothed ring one fixedly connected to the lower side of the inner wall of the installation chamber, a limiting ring fixedly connected to the upper side of the inner wall of the installation chamber, a sample chamber slidably connected to the middle of the limiting ring, a toothed ring two fixedly connected to the outer wall of the sample chamber, the toothed ring two meshing with the toothed ring one, a spring sleeved on the outside of the sample chamber, and a sample partition fixedly connected inside the sample chamber.

[0008] Using the above technical solution, soil samples are collected through the sampling component. Then, the sealed cover is opened, and the collected soil samples are placed into the sample chamber through the collection port. When collecting soil samples from the next area, the sample chamber is pushed upwards, causing it to move upwards. During this process, the second toothed ring moves upwards and compresses the spring, disengaging the second toothed ring from the first toothed ring. At this point, the sample chamber can be rotated to rotate the sample partition inside, causing the next area without a soil sample to rotate to below the collection port. Simultaneously, the sample chamber is released, and under the action of the spring, the second toothed ring is pressed back against the top of the first toothed ring, causing the second toothed ring and the first toothed ring to re-engage, thus locking the adjusted sample chamber back in place.

[0009] Furthermore, the upper and lower sides of the installation chamber are fixedly connected with fixing rings, and the outer side of the sample chamber is slidably connected to the middle of the fixing rings;

[0010] The above technical solution ensures that the sample chamber remains stable when it moves up and down and rotates, thanks to the two fixing rings.

[0011] Furthermore, the second toothed ring is disposed between the first toothed ring and the limiting ring;

[0012] The above technical solution restricts the second toothed ring between the first toothed ring and the limiting ring, preventing the sample chamber from falling out of the installation chamber during movement.

[0013] Furthermore, the top end of the spring is disposed at the bottom of the limiting ring, and the bottom end of the spring is disposed at the top of the toothed ring II;

[0014] Through the above technical solution, the spring is restricted to the outside of the sample chamber by the cooperation of the toothed ring two and the limiting ring. Then, through the support of the limiting ring, the spring can apply a downward pressure to the toothed ring two, thereby ensuring that the toothed ring two and the toothed ring one are engaged and locked.

[0015] Furthermore, the detection component includes a housing, the outer side of which is fixedly connected to the inside of the frame. Inside the housing, an electrochemical workstation, a near-infrared spectral sensor, a capacitive moisture probe, and a display screen are disposed. A cross plate is disposed between the electrochemical workstation, the near-infrared spectral sensor, the capacitive moisture probe, and the display screen, and the cross plate is fixedly connected to the inside of the housing.

[0016] By separating the connecting shell and the installation chamber, the soil sample stored inside the sample chamber can be taken out. Then, the collected soil sample can be detected and analyzed by an electrochemical workstation, a near-infrared spectral sensor, and a capacitive moisture probe to determine whether the soil sample is contaminated. The detection data will be displayed on the screen.

[0017] Furthermore, a controller is installed inside the housing, and the electrochemical workstation, near-infrared spectroscopy sensor, and capacitive moisture probe are electrically connected to the controller, and the controller and the display screen are electrically connected;

[0018] Through the above technical solution and the connection of the controller, users can operate the detection components on the display screen, thereby improving the convenience of the device in the detection process.

[0019] Furthermore, the sampling component includes a storage compartment, a hydraulic motor is installed on one side inside the storage compartment, a drill rod is installed on the other side inside the storage compartment, and a connector is fixedly connected to the output end of the storage compartment, with the connector and the drill rod engaging with each other;

[0020] The above technical solution connects the drill rod with the joint structure on the drill rod and the hydraulic motor with the joint on the hydraulic motor. With the bolts in place, the hydraulic motor and the drill rod are assembled together. Then, the hydraulic motor drives the drill rod to rotate, collect the underground soil, and then put it into the sample chamber.

[0021] Furthermore, the outer side of the connecting shell is fixedly connected to the inside of the frame, and the top of the storage compartment is fixedly connected to the center of the bottom of the frame;

[0022] With the above technical solution, the entire device is mounted on a frame, making it convenient for users to carry the device for regional soil sampling.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this invention, the meshing and locking structure of toothed ring one and toothed ring two in the collection component, combined with spring force and the gravity of the sample chamber, enables independent storage and rapid switching of soil samples from multiple regions. During operation, simply press the sample chamber to separate the toothed rings, rotate to switch to an unused area, and it automatically resets and locks, ensuring that soil samples from different sampling points are stored separately in the independent spaces defined by the sample partitions, avoiding cross-contamination. The cooperation of the fixing ring and the limiting ring further improves the stability of the sample chamber movement, and the transparent connecting shell facilitates observation of the sample position.

[0025] 2. In this invention, by integrating the detection component, sampling component, and collection component into the same frame, the device achieves integrated operation of soil sampling, storage, and analysis. During sampling, a hydraulic motor drives the drill rod to directly collect soil samples and transfer them to the collection component. The electrochemical workstation, near-infrared spectroscopy sensor, and moisture probe integrated in the detection component can simultaneously analyze soil pollutant composition, organic matter content, and humidity. The data is integrated by the controller and displayed in real time. This highly integrated design reduces equipment carrying and sample transfer steps, significantly improving field detection efficiency while avoiding secondary contamination of samples by the external environment and ensuring the accuracy of the test results.

[0034] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] Referring to Figure 1, one embodiment of this utility model is provided: a comprehensive soil testing device, including a frame 1, a testing component installed on one side of the frame 1, a collection component installed on the other side of the frame 1, and a sampling component set in the middle of the frame 1; the testing component can further analyze and test the collected soil samples to determine the soil pollution status, and the collection component can collect the soil samples collected in the sampling component.

[0036] Referring to Figures 1, 4, 5, and 6, the collection assembly includes a connecting shell 13. A collection port 14 is fixedly connected to the top of the connecting shell 13, and a sealing cap 15 is threaded onto the top of the collection port 14. By opening the sealing cap 15, the collected soil sample can be placed inside the collection assembly for storage. An installation chamber 16 is threaded onto the bottom of the connecting shell 13. By rotating the installation chamber 16, the installation chamber 16 and the connecting shell 13 can be separated, and the soil sample stored inside the collection assembly can be taken out. A toothed ring 17 is fixedly connected to the lower inner wall of the mounting chamber 16, and a limit ring 18 is fixedly connected to the upper inner wall of the mounting chamber 16. A sample chamber 19 is slidably connected to the middle of the limit ring 18. A toothed ring 20 is fixedly connected to the outer wall of the sample chamber 19, and the toothed ring 20 and the toothed ring 17 are engaged. A spring 21 is sleeved on the outer side of the sample chamber 19. Under normal conditions, the elastic force generated by the spring 21 and the weight of the mounting chamber 16 itself can lock the toothed ring 20 and the toothed ring 17, thereby preventing the sample chamber 19 from rotating. When it is necessary to collect another set of soil samples, simply push upwards. The sample chamber 19 allows the toothed rings 20 and 17 to separate. At this point, the sample chamber 19 can be rotated to allow the internal sample partition 23 to rotate, moving the next area without a soil sample to below the collection port 14. Simultaneously, the sample chamber 19 is released, and under the force of the spring 21 and the gravity of the sample chamber 19 and the soil sample inside, the toothed rings 20 and 17 re-engage and lock, thus fixing the sample chamber 19 inside the mounting chamber 16. This ensures that soil samples collected from different locations can be stored in different areas for subsequent testing and analysis. The sample chamber 19 is fixedly connected to the sample partition 23, which divides the interior of the sample chamber 19 into multiple spaces for holding soil samples.

[0037] Referring to Figures 4-6, fixing rings 22 are fixedly connected to both the upper and lower sides of the mounting chamber 16, and the outer side of the sample chamber 19 is slidably connected to the middle of the fixing rings 22. The upper and lower fixing rings 22 restrict the sample chamber 19, ensuring its stability during pressing and movement. A second toothed ring 20 is positioned between a first toothed ring 17 and a limiting ring 18. The first toothed ring 17 and the limiting ring 18 restrict the second toothed ring 20, preventing the sample chamber 19 from detaching from the mounting chamber 16 during pressing and movement. The top end of the spring 21 is located at the bottom of the limiting ring 18, and the bottom end of the spring 21 is located at the top of the second toothed ring 20. The limiting ring 18 restricts the spring 21, allowing it to apply a downward elastic force, thus tightly pressing the second toothed ring 20 against the top of the first toothed ring 17. Simultaneously, the weight of the sample chamber 19 ensures that the second toothed ring 20 and the first toothed ring 17 are engaged and locked, preventing the sample chamber 19 from rotating.

[0038] Referring to Figures 1 and 2, the detection assembly includes a housing 2, which is fixedly connected to the outside of a frame 1. Inside the housing 2 are an electrochemical workstation 4, a near-infrared spectral sensor 5, a capacitive moisture probe 6, and a display screen 7. The electrochemical workstation 4 is a CS360 high-frequency impedance electrochemical workstation, the near-infrared spectral sensor 5 is a NIR-M-R2 reflective near-infrared spectrometer, and the capacitive moisture probe 6 is an AKF-IS2019C moisture analyzer. A crossbeam 8 is positioned between the electrochemical workstation 4, the near-infrared spectral sensor 5, the capacitive moisture probe 6, and the display screen 7, and is fixedly connected inside the housing 2. A controller is installed inside the housing 2. The electrochemical workstation 4, the near-infrared spectral sensor 5, and the capacitive moisture probe 6 are electrically connected to the controller, and the controller is electrically connected to the display screen 7. The controller allows users to operate the device more conveniently when detecting the pollution level of soil samples, making the detection process more efficient and convenient.

[0039] Referring to Figures 1 and 3, the sampling assembly includes a storage chamber 9. A hydraulic motor 10 is located on one side of the storage chamber 9, and a drill rod 11 is located on the other side. A connector 12 is fixedly connected to the output end of the storage chamber 9, and the connector 12 and the drill rod 11 engage. A connecting shell 13 is fixedly connected to the outside of the frame 1, and the top of the storage chamber 9 is fixedly connected to the center of the bottom of the frame 1. By engaging the connector on the drill rod 11 with the connector 12 on the hydraulic motor 10, and then locking them together with bolts, the drill rod 11 and the hydraulic motor 10 are easily assembled. The hydraulic motor 10 can then drive the drill rod 11 to rotate, drilling and sampling the soil, making the operation more convenient and efficient.

[0040] Working principle: When using the device for soil pollution testing, staff can carry the device to the testing site using the handle structure installed on the top of the device. Then, staff open the cover on the side of the storage compartment 9 to remove the hydraulic motor 10 and drill rod 11. Using the connector 12 and bolts installed on the hydraulic motor 10, the hydraulic motor 10 and drill rod 11 are assembled together. Then, by operating the hydraulic motor 10, the drill rod 11 is driven to rotate, and soil samples are taken from the target location.

[0041] The collected soil samples are then collected and placed inside the collection port 14 after the sealing cover 15 is opened. The samples will eventually enter the installation chamber 16 through the collection port 14 and fall into one of the spaces separated by the sample partition 23. Then, the staff presses the sample chamber 19 to move it upward, thereby disengaging the toothed rings 20 and 17 on the outside of the sample chamber 19, allowing the sample chamber 19 to rotate inside the installation chamber 16. At this time, the staff rotates the sample chamber 19 and observes through the transparent connecting shell 13 whether the area separated by the sample partition 23 inside the sample chamber 19 has moved below the collection port 14. When the next area moves below the collection port 14, the sample chamber 19 is released. The elastic force of the spring 21, the weight of the sample chamber 19 itself and the sample inside, causes the installation chamber 16 to move downward, thereby re-engaging and locking the toothed rings 20 and 17 to prevent the sample chamber 19 from rotating again. This ensures that each collected and stored soil sample can be independently separated and stored, providing convenience for subsequent analysis.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
