Description

Technical Field

[0001] The present application relates to the technical field of soil detection, and in particular to a collection device for soil detection and analysis. Background Art

[0002] In the fields of soil science and environmental monitoring, soil testing and analysis are important means of assessing soil quality, fertility, and contamination. Soil sampling, as the first step in testing and analysis, directly impacts the reliability of subsequent analytical results through its accuracy and convenience.

[0003] In actual applications, existing soil testing samplers are mostly driven manually or by simple mechanical means, such as manual auger. These tools require the operator to exert a large force to push the sampler deep into the soil during sampling, which is particularly laborious for soils with hard texture or low water content. After completing the soil sampling, how to effectively separate the soil in the sampler from the surrounding soil and remove it smoothly is another problem that needs to be solved. Traditional methods often try to separate the soil by shaking or knocking the sampler, but this method is not only inefficient, but also easily destroys the integrity of the soil sample, affecting the accuracy of subsequent analysis results. Especially for deep soil sampling, due to the high pressure and strong viscosity of the soil, the separation and removal process is more difficult.

[0004] In view of the above problems, a collection device for soil detection and analysis is now designed. Utility Model Content

[0005] The embodiment of the present application provides a collection device for soil detection and analysis to solve the problem in the related art that the soil detection sampler penetrates into the soil, effectively separates the soil in the sampler from the surrounding soil, and smoothly removes it, which is relatively laborious and inefficient.

[0008] A driving motor is provided at the bottom of the connecting seat, and the sampling cylinder is connected to the output shaft of the driving motor. The driving motor is used to drive the sampling cylinder to rotate, and an annular blade is provided at the bottom of the sampling cylinder;

[0009] The annular blade is provided with a detachable separation rod.

[0010] In some embodiments, the support frame includes a main disk body, and a plurality of annularly distributed connecting blocks are provided on the main disk body, and the bottom of the connecting blocks is threadedly connected to the support rod.

[0011] In some embodiments, the driving member is an electric push rod, and a through hole for extending the piston rod of the electric push rod is opened at the center of the main disk body. The piston rod of the electric push rod passes through the through hole and is fixedly connected to the connecting seat.

[0012] In some embodiments, the sampling cylinder is cylindrical, and a cavity for soil sampling is defined at the bottom of the sampling cylinder.

[0013] In some embodiments, through holes are formed on the annular blades, and the separation rods are inserted into the through holes.

[0014] In some embodiments, a limiting plate abutting against the annular blade is provided at one end of the separation rod, and a bolt is threadedly connected to the other end of the separation rod, and the separation rod is fixed to the annular blade through the limiting plate and the bolt.

[0024] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] The embodiment of the present application provides a collection device for soil detection and analysis, which can solve the problem in the related art that the soil detection sampler penetrates into the soil, effectively separates the soil in the sampler from the surrounding soil, and smoothly removes it, which is relatively laborious and inefficient.

[0026] See also Figure 1-Figure 3 A collection device for soil detection and analysis includes: a support frame 1, a sampling cylinder 2, and a connecting seat 3 arranged at the bottom of the support frame 1, the sampling cylinder 2 is used to collect soil, a driving member 4 is provided above the support frame 1, the driving member 4 is connected to the connecting seat 3 and is used to drive the connecting seat 3 to move up and down, a driving motor 5 is provided at the bottom of the connecting seat 3, the sampling cylinder 2 is connected to the output shaft of the driving motor 5, and the driving motor 5 is used to drive the sampling cylinder 2 to rotate, and an annular blade 6 is provided at the bottom of the sampling cylinder 2; a detachable separating rod 7 is provided on the annular blade 6.

[0027] Place the sampling device above the soil to be tested, ensure that the support frame 1 is stable, and the sampling tube 2 and the annular blade 6 are in the initial position.

[0028] Controlled by the drive element 4, the connector 3 lowers the sampling tube 2 and the drive motor 5. Simultaneously, the drive motor 5 activates, rotating the sampling tube 2. The annular blade 6 at the bottom rotates and cuts the soil, allowing the sampling tube 2 to penetrate deeply into the soil. When the sampling tube 2 reaches the desired depth, the drive element 4 reverses, returning the sampling tube 2 and the drive motor 5 to their initial position. At this point, the sampling tube 2 is filled with a predetermined amount of soil sample.

[0029] After the sampling tube 2 is raised, the detachable separator rod 7 is installed on the annular blade 6. This step is to provide the necessary support and cutting force during the subsequent soil sample segmentation process. The drive member 4 is activated again, driving the sampling tube 2 and the annular blade 6 with the separator rod 7 installed to descend, so that the separator rod 7 is inserted into the collected cylindrical soil sample. At this time, the separator rod 7 cuts the sampled soil in half. Subsequently, the drive motor 5 drives the separator rod 7 to rotate 180 degrees, cutting from the bottom of the soil sample, separating the soil sample from the ground.

[0030] After the initial segmentation is completed, the separation rod 7 rotates another 90°, at which point it becomes a support for the segmented soil sample, preventing it from scattering during the ascent of the sampling tube 2. Finally, the driving member 4 operates again, driving the sampling tube 2 and the segmented and supported soil sample inside to ascend, completing the entire soil sampling process.

[0031] By automatically controlling the lifting and rotation of the sampling tube and utilizing the coordinated work of the annular blade and separation rod, rapid and accurate soil sampling is achieved, greatly improving sampling efficiency.

[0032] The circular blades evenly cut the soil during rotation, eliminating the uneven sampling that can occur with manual sampling. Furthermore, the separation rod design ensures the integrity of the soil sample during extraction, minimizing the impact of sample breakage on analytical results.

[0033] This device is suitable for sampling soils with different textures and water contents. By adjusting the parameters of the drive component and the drive motor, the sampling depth and rotation speed can be flexibly controlled to meet different sampling requirements.

[0034] The entire sampling process is automated, making it easy and quick to operate, reducing the need for operator skill and physical strength. Furthermore, the detachable separation rod design facilitates cleaning and replacement, extending the device's service life and ease of maintenance.

[0035] Specifically, the support frame 1 in this embodiment includes a main plate body 11, on which a plurality of annularly distributed connecting blocks 12 are provided. The bottom of the connecting blocks 12 is threadedly connected to a supporting rod 13. The bottom of the supporting rod 13 is provided with a supporting plate.

[0036] In this embodiment, the specific design of the support frame 1 further enhances the stability and adjustability of the collection device. The following is a detailed description of the various parts of the support frame 1 and the beneficial effects it brings:

[0037] The main plate 11 provides a stable support base for the entire device. The connecting block 12, serving as the connection point between the support rod 13 and the main plate 11, helps distribute the weight and enhance stability. Furthermore, the annular design makes the support frame 1 more compact and aesthetically pleasing.

[0038] Support rod 13 is connected to the bottom of connecting block 12 via a threaded connection. This design allows the user to adjust the length of support rod 13 as needed to accommodate sampling requirements at different heights and terrains. Furthermore, the threaded connection provides excellent stability, preventing support rod 13 from loosening or falling off during use. A support plate is provided at the bottom of support rod 13. This plate increases the contact area with the ground, further enhancing the stability of the entire device.

[0039] In this embodiment, the driving member 4 is an electric push rod. A through hole for the piston rod of the electric push rod to extend is opened at the center of the main disk body 11. The piston rod of the electric push rod passes through the through hole and is fixedly connected to the connecting seat 3.

[0040] In this embodiment, selecting an electric push rod as the driving member 4 is an efficient and practical design.

[0041] The electric push rod is driven by electricity and can quickly and accurately control the extension and contraction of the piston rod, thereby driving the connection base 3 and the sampling tube 2 up and down. This driving method is more efficient than manual or mechanical transmission and can significantly improve the efficiency of sampling work.

[0042] The through hole is provided at the center of the main disk body 11 so that the piston rod of the electric push rod can smoothly pass through and be connected to the connecting seat 3 .

[0043] After the piston rod of the electric push rod passes through the through hole, it is fixedly connected to the connecting base 3. This connection is usually fixed with fasteners such as bolts and pins to ensure a firm and reliable connection. During the sampling process, this fixed connection can prevent the connecting base 3 from shaking or falling off, thereby ensuring smooth sampling.

[0044] In this embodiment, the sampling tube 2 is cylindrical, and a cavity 21 for soil sampling is provided at the bottom of the sampling tube 2 .

[0045] The cylindrical structure has good stability and load-bearing capacity, and can resist the resistance of the soil during the sampling process without being easily deformed or damaged. This is of great significance for ensuring that the sampling tube 2 can maintain its shape intact and not twist when it penetrates the soil.

[0046] The uniform cross-sectional area of ​​the cylindrical sampling tube 2 allows for uniform soil cutting during sampling, reducing sampling unevenness caused by irregular shapes. This helps obtain more representative soil samples and improves the accuracy of analytical results. Furthermore, the cylindrical structure is relatively simple, making it easy to manufacture and maintain.

[0047] Cavity 21 is the space at the bottom of sampling tube 2 that holds the soil sample. Once sampling tube 2 is inserted into the soil to a predetermined depth, the soil is rotated and pressed downward, forcing it into cavity 21, thereby sampling. Cavity 21 is designed to ensure that soil can enter and remain within it, preventing leakage or dislodging during the sampling process.

[0048] It should be noted that a through hole 8 is relatively opened on the annular blade 6 , and the separating rod 7 is inserted into the through hole 8 .

[0049] The plug-in connection between through-hole 8 and separator rod 7 ensures a more stable connection. During sampling, even when encountering significant soil resistance or vibration, separator rod 7 remains in place and functions reliably. Furthermore, when separator rod 7 needs to be replaced or cleaned, it can simply be removed from through-hole 8. This design simplifies maintenance and improves work efficiency.

[0050] Specifically, in this embodiment, one end of the separation rod 7 is provided with a limiting plate 71 that abuts against the annular blade 6, and the other end of the separation rod 7 is threadedly connected with a bolt, and the separation rod 7 is fixed to the annular blade 6 through the limiting plate 71 and the bolt.

[0051] The limiting plate 71 abuts against the annular blade 6 and provides a clear positioning point for the separating rod 7. Simultaneously, it also plays a role in supporting the separating rod 7 to prevent it from deflecting or shaking during operation.

[0052] The bolt is connected to the other end of the separation rod 7 by a thread, and works together with the limit plate 71 to firmly fix the separation rod 7 on the annular blade 6. This fastening connection method ensures the stability and reliability of the separation rod 7 during the sampling process.

[0053] The threaded connection of the bolts also allows the user to adjust the tightness thereof as required. If the separator rod 7 is found to be loose during use, the fixing effect can be strengthened by tightening the bolts; conversely, if the separator rod 7 needs to be replaced or removed, the bolts can be loosened for operation.

[0054] It should be noted that the separation rod 7 is located on the center line of the annular blade 6.

[0055] The centerline position allows the separator rods 7 to be evenly distributed along the cutting path of the annular blade 6, dividing the soil sample into two even halves. When the separator rods 7 rotate with the annular blade 6, they can more effectively penetrate the soil and assist in cutting, thereby improving sampling efficiency.

[0056] Designing the separation rod 7 on the center line also helps to achieve a compact structure of the sampling device.

[0057] In practice, the separator rod 7 can be connected to the annular blade 6 and maintained on the centerline in a variety of ways. For example, the aforementioned combination of the retaining plate 71 and bolts can be used to secure the separator rod 7 and ensure its position on the centerline. Furthermore, a specialized fixture or bracket can be designed to support and position the separator rod 7, ensuring it remains in the correct position.

[0058] In addition, the support frame 1 in this embodiment is provided with a handle.

[0059] In one embodiment, Figure 4 As shown, a reducer is also included, which is arranged at the bottom of the driving motor 5. The output shaft of the driving motor 5 is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the sampling tube 2.

[0060] The speed reducer's primary function is to convert the high-speed, low-torque output of the drive motor 5 into a low-speed, high-torque output. This is particularly important for soil sampling, as soil typically has high resistance and requires a high torque for effective cutting and sampling. The speed reducer improves the cutting capacity of the sampling barrel 2 without increasing the power of the drive motor 5.

[0061] When the drive motor 5 and the sampling tube 2 are directly connected, if a large resistance is encountered during the sampling process, the drive motor 5 may be overloaded or even damaged. The reducer can absorb and mitigate this impact, thereby protecting the drive motor 5 from damage.

[0062] As a preferred embodiment, a battery and a controller (not shown in the figure) are provided on the support frame 1, the battery is electrically connected to the controller, the controller is electrically connected to the electric push rod and the drive motor 5 respectively, the battery supplies power to the electric push rod and the drive motor 5, and the controller is used to control the start and stop of the electric push rod and the drive motor 5.

[0063] As the primary power source for the sampling device, the battery provides stable power to the electric actuator and drive motor 5. This self-sufficient power supply eliminates reliance on external power sources, allowing for flexible use in a variety of environments. By selecting an appropriate battery capacity, the sampling device can be guaranteed to operate continuously for extended periods on a single charge, meeting diverse sampling needs.

[0064] The controller, as the brain of the sampling device, is responsible for receiving operating instructions and controlling the start and stop of the electric push rod and the drive motor 5. Through a preset program, the controller can achieve precise control of the sampling device.

[0065] Users can operate the sampling device through buttons on the controller or remote control, without complicated wiring and debugging processes. This greatly reduces the difficulty of operation and improves work efficiency.
