Description

Technical Field

[0001] This utility model relates to the field of soil sampler technology, specifically a combined soil sampler for soil testing. Background Technology

[0002] In the field of soil testing, accurate and efficient soil sample collection is fundamental to obtaining reliable testing data. The quality of soil sample collection directly affects the accuracy of analysis of various indicators such as soil composition, fertility, and pollution levels, thereby influencing decision-making and practices in multiple fields, including agricultural production, environmental monitoring, and geological research.

[0003] Traditional soil samplers are complex to operate in practice and require a high level of skill from operators. For example, some manual soil samplers require operators to have certain experience and skills to accurately insert the sampler into the soil and collect representative samples. For people without professional skills, it is difficult to master the operation method in a short time. This not only reduces sampling efficiency but may also lead to inaccurate sample collection, affecting subsequent test results. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a combined soil sampler for soil testing, which solves the problems of complex operation and high skill requirements for operators in practical applications of soil samplers.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a combined soil sampler for soil testing, comprising a handle and a limiting component. The top of the limiting component is fixedly connected to the outer wall of the handle, and an installation component is slidably connected to the inner wall of the limiting component. The installation component includes a sampling shell, with an inclined groove in the bottom wall of the sampling shell for easy insertion into the soil. A vibration guide column is slidably connected to the inner wall of the sampling shell, and a pressure plate is fixedly connected to the outer wall of the vibration guide column. Grooves are formed in the walls on both sides of the vibration guide column, and the grooves are arranged in a linear array along the central axis of the vibration guide column. The outer wall of the pressure plate is slidably connected to the inner wall of the sampling shell.

[0008] Preferably, the limiting component includes a limiting shell, the outer wall of which is slidably connected to a slip ring, and the inner wall of the slip ring is rotatably connected to a roller via a rotating shaft, wherein the outer wall of the rotating shaft is rotatably connected to the inner wall of the roller.

[0009] Preferably, the outer wall of the rotating shaft is fixedly connected to the inner wall of the slip ring, and limit frames are fixedly connected to the outer walls of both sides of the limiting shell. The outer walls of the limit frames are fitted with buckles. The limit frames are used to restrict the position of the buckles.

[0010] Preferably, the bottom of the buckle is fixedly connected to the top of the sampling shell, and the sampling shell has striking windows in the walls on both sides to facilitate the sliding of the rollers. The bottom of the limiting shell is in contact with the top of the sampling shell.

[0011] Preferably, the outer wall of the roller is in contact with the outer wall of the vibration guide column, the outer wall of the vibration guide column is slidably connected to the inner wall of the limiting shell through the mounting groove, and the mounting groove is opened in the wall of the vibration guide column.

[0012] (III) Beneficial Effects

[0013] This invention provides a combined soil sampler for soil testing. It has the following advantages:

[0014] (I) This combined soil sampler for soil testing, by setting a limiting component, allows the sampling shell to be inserted into the soil simply by grasping the handle and applying downward force. Subsequently, the limiting component generates vibration to assist sampling. The operation steps are simple and clear. Even personnel without professional skills can quickly get started after simple training, which improves the efficiency of sampling work. It is especially suitable for scenarios that require the collection of a large number of soil samples. By sliding the sliding ring up and down, the roller can be driven to slide on the guide column. The groove on the guide column forces the roller to vibrate, thereby causing the guide column to disperse the soil. This design allows the operator to flexibly control the frequency and intensity of vibration according to different soil textures and sampling needs, further improving the convenience and adaptability of sampling.

[0015] (II) This combined soil sampler for soil testing, through the installation components and the coordinated work of the pressure plate and the guide column, not only assists the soil in entering the sampling shell during sampling, but also, after sampling, the guide column moves downward to drive the pressure plate, which can smoothly press the soil sample out of the sampling shell, ensuring the integrity and accessibility of the sample, and providing a reliable basis for subsequent soil testing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a combined soil sampler for soil testing, including a handle 1 and a limiting component 2. The top of the limiting component 2 is fixedly connected to the outer wall of the handle 1, and an installation component 3 is slidably connected to the inner wall of the limiting component 2. The installation component 3 includes a sampling shell 34, a vibration guide column 31 is slidably connected to the inner wall of the sampling shell 34, and a pressure plate 35 is fixedly connected to the outer wall of the vibration guide column 31. Grooves 32 are provided in the walls on both sides of the vibration guide column 31, and the grooves 32 are arranged linearly along the central axis of the vibration guide column 31. The outer wall of the pressure plate 35 is slidably connected to the inner wall of the sampling shell 34. After sampling, the operator can release the buckle 24 from the limiting frame 23, then remove the vibration guide column 31 from the limiting shell 21, then grasp the sampling shell 34 and hold its position, and then move the vibration guide column 31 downward, thereby driving the pressure plate 35 downward to press the soil sample out of the sampling shell 34.

[0024] The limiting component 2 includes a limiting shell 21. A slip ring 22 is slidably connected to the outer wall of the limiting shell 21. A roller 26 is rotatably connected to the inner wall of the slip ring 22 via a rotating shaft 27. The outer wall of the rotating shaft 27 is rotatably connected to the inner wall of the roller 26. The outer wall of the rotating shaft 27 is fixedly connected to the inner wall of the slip ring 22. Limiting frames 23 are fixedly connected to the outer walls on both sides of the limiting shell 21. Buckles 24 are snapped onto the outer walls of the limiting frames 23.

[0025] The bottom of the buckle 24 is fixedly connected to the top of the sampling shell 34. The sampling shell 34 has impact windows 25 on both sides of its walls. The bottom of the limiting shell 21 is in contact with the top of the sampling shell 34. The outer wall of the roller 26 is in contact with the outer wall of the guide column 31. The outer wall of the guide column 31 is slidably connected to the inner wall of the limiting shell 21 through the mounting groove 33. The mounting groove 33 is opened in the wall of the guide column 31. By simply sliding the sliding ring 22 up and down, the roller 26 on the rotating shaft 27 is driven to slide on the guide column 31 through the sliding ring 22. The roller 26 is forced to slide in the groove 32 through the groove on the guide column 31, thereby causing the guide column 31 to generate vibration force, which can disperse the soil through the guide column 31.

[0026] This modular soil sampler for soil testing mainly consists of a handle 1, a limiting component 2, and an installation component 3. The handle 1 provides a gripping area for the operator to easily operate the sampler. The top of the limiting component 2 is fixedly connected to the outer wall of the handle 1 to limit and guide the installation component 3, ensuring the stable operation of the installation component 3 during operation. The installation component 3 is the core part for soil sampling, and completes the collection of soil samples through the synergistic effect of its internal structure.

[0027] The mounting assembly 3 consists of a sampling shell 34, a vibration guide column 31, a pressure plate 35, a groove 32, and a mounting slot 33. The sampling shell 34 is the main structure of the mounting assembly 3. The vibration guide column 31 is slidably connected to its inner wall to guide the movement of the vibration guide column 31. The pressure plate 35 is fixedly connected to the outer wall of the vibration guide column 31. The outer wall of the pressure plate 35 is slidably connected to the inner wall of the sampling shell 34, so that the pressure plate 35 can move up and down inside the sampling shell 34.

[0028] The walls on both sides of the vibration guide column 31 are provided with grooves 32, and the grooves 32 are arranged in a linear array along the central axis of the vibration guide column 31. When soil sampling is performed, simply grasp the handle 1 and apply a downward force to the handle 1, so that the sampling shell 34 is inserted into the soil. Then, vibration is generated by the limiting component 2, which facilitates the soil sampling work.

[0029] The limiting assembly 2 consists of a limiting shell 21, a slip ring 22, a roller 26, a rotating shaft 27, a limiting frame 23, a buckle 24, and a striking window 25. The outer wall of the limiting shell 21 is slidably connected to the slip ring 22, which can slide up and down on the outer wall of the limiting shell 21. The inner wall of the slip ring 22 is rotatably connected to the roller 26 through the rotating shaft 27. The outer wall of the rotating shaft 27 is rotatably connected to the inner wall of the roller 26, and the outer wall of the rotating shaft 27 is fixedly connected to the inner wall of the slip ring 22, so that the roller 26 can rotate around the rotating shaft 27.

[0030] Limiting frames 23 are fixedly connected to the outer walls on both sides of the limiting shell 21. Buckles 24 are snapped onto the outer walls of the limiting frames 23. The bottom of the buckles 24 is fixedly connected to the top of the sampling shell 34. This connection method connects the limiting shell 21 and the sampling shell 34 together. At the same time, the limiting frames 23 and buckles 24 play the role of limiting and fixing, ensuring that the sampling shell 34 will not shake or shift during operation.

[0031] The sampling shell 34 has striking windows 25 on both sides of its walls. The bottom of the limiting shell 21 is in contact with the top of the sampling shell 34. When it is necessary to operate the guide column 31, the guide column 31 can be struck through the striking windows 25 to achieve the movement of the guide column 31.

[0032] The outer wall of the roller 26 contacts the outer wall of the guide column 31. The outer wall of the guide column 31 is slidably connected to the inner wall of the limiting shell 21 through the mounting groove 33. The mounting groove 33 is opened in the wall of the guide column 31. The roller 26 rolls along the outer wall of the guide column 31 under the drive of the slip ring 22. Thus, by simply sliding the slip ring 22 up and down, the roller 26 on the rotating shaft 27 is driven to slide on the guide column 31 through the slip ring 22. And through the groove 32 on the guide column 31, the roller 26 is forced to slide in the groove 32, thereby causing the guide column 31 to generate vibration force, so as to disperse the soil through the guide column 31.

[0033] The operator holds the handle 1 and places the sampler at the location of the soil to be sampled. The connection between the limiting frame 23 and the buckle 24 ensures that the limiting shell 21 and the sampling shell 34 are securely connected.

[0034] The operator can strike the guide column 31 through the striking window 25, causing the guide column 31 to move downward inside the sampling shell 34. The slip ring 22 slides on the outer wall of the limiting shell 21, driving the roller 26 to roll along the outer wall of the guide column 31, assisting the movement of the guide column 31.

[0035] Once the guide column 31 and the pressure plate 35 reach the appropriate positions, the soil sample is collected into the sampling shell 34. After sampling is completed, the operator can release the latch 24 from the limiting frame 23, then remove the guide column 31 from the limiting shell 21, grasp the sampling shell 34 and maintain its position, and then move the guide column 31 downwards, thereby driving the pressure plate 35 downwards and pressing the soil sample out of the sampling shell 34.

[0036] During use, regularly check whether the connection between the limit frame 23 and the buckle 24 is loose, whether the movement of the slip ring 22 and the roller 26 is smooth, and whether the guide column 31 and the pressure plate 35 are damaged. If there are any problems, repair or replace them in time to ensure the normal operation of the soil sampler.
