[0002] Soil aggregates are the foundation of soil fertility and have a significant impact on soil moisture, air, and nutrient cycling. Therefore, accurate collection of soil aggregate samples is of great importance for soil research and agricultural production. Traditional soil sampling methods, such as using shovels, are difficult to preserve the original shape and structure of soil samples, especially large water-stable aggregates, which are easily destroyed.

[0003] In the prior art, patent application number 2022226622773 discloses a soil aggregate sampling device that restricts the shape of the soil sample through a sampling cylinder, push plate, push rod, and other structures. However, this device still has the problem of easy separation between the lower and upper soil layers during the sampling process, which changes the volume of the sample and is not conducive to the subsequent detection of water-stable large aggregates.

[0004] To address this issue, a convenient soil water-stable large aggregate sampling device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a convenient soil water-stable large aggregate sampling device to solve the problems existing in the prior art, and to provide a sampling tool that can maintain the original state of the soil sample and prevent soil aggregates from separating during the sampling process.

[0007] An uncirculated sampler includes an outer box, on which a four-edged blade is fixedly connected. A sample container is placed inside the outer box. Two cutting blade inlets are opened on the outer box and are arranged opposite to each other. The sample container is detachably connected to a lid.

[0008] A soil cutting blade, which is inserted into the soil cutting blade inlet.

[0009] Preferably, the cutting blade includes a blade, a handle is fixedly connected to the blade, a handle rubber pad is fixedly connected to the handle, and the blade is adapted to the cutting blade inlet.

[0010] Preferably, the outer box has an internal track, and the blade slides within the internal track.

[0011] This utility model discloses the following technical advantages: In this device, the undisturbed sampler ensures that the collected soil samples remain in their original state, avoiding structural damage. The sample container design protects the soil samples from compression, contamination, and damage during transportation. The sampling process is simple and straightforward, requiring no complex operating skills. The overall device design is compact, easy to carry and operate, and suitable for field sampling work. This utility model has the advantages of accurate sampling, integrity protection, ease of operation, and high portability. Attached Figure Description

Detailed Implementation

[0018] 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.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figure 1-4This utility model provides a convenient soil water-stable large aggregate sampling device, comprising:

[0021] The original sampler 200 includes an outer box 210, a four-edged blade 220 fixedly connected to the outer box 210, a sample box 310 placed inside the box, two soil cutting blade inlets 230 opened on the outer box 210, the two soil cutting blade inlets 230 are arranged opposite to each other, and the sample box 310 is detachably connected to a box cover 320.

[0022] Cutting blade 100, inserted into cutting blade inlet 230.

[0023] In this device, the four-edged blade 220 is convenient for insertion into the soil, and the sample container 310 is used to hold soil samples. When using it, a pit needs to be dug first, and the side wall of the pit should be vertical. Then, the device is placed on the side wall so that the entry of the cutting blade protrudes from the ground surface. The back of the outer box 210 is struck with a hammer to make the four-edged blade 220 enter the soil. The appropriate sampling thickness is selected as needed, and then the cutting blade 100 is inserted into the cutting blade entry 230 to separate the soil entering the sample container 310 from the external soil, thereby completing the sampling.

[0024] Further optimization of the design: the soil cutting blade 100 includes a blade 110, a handle 120 fixedly connected to the blade 110, a handle rubber pad 130 fixedly connected to the handle 120, and the blade 110 is adapted to the soil cutting blade inlet 230.

[0025] The worker holds the handle 120 and inserts the blade 110 into the cutter inlet 230.

[0026] The design is further optimized by providing an internal track 240 inside the outer casing 210, within which the blade 110 slides.

[0027] The internal track 240 facilitates the sliding of the blade 110.

[0028] Advantages of this device:

[0029] Precise sampling: The undisturbed sampler 200 ensures that the collected soil samples remain in their original state, avoiding structural damage.

[0030] Integrity protection: The design of the sample container 310 protects soil samples from compression, contamination and damage during transportation.

[0031] Easy to operate: The sampling process is simple and straightforward, requiring no complicated operating skills to complete.

[0032] Highly portable: The device has a compact overall design, making it easy to carry and operate, and suitable for field sampling work.

[0033] This device employs an undisturbed sampler and a soil cutter. Soil is collected by fixing the undisturbed sampler and using a soil hammer, while the soil cutter facilitates the separation of the collected sample from the soil layer. The device's compact design enables precise collection of the desired soil sample and ensures the stability of the soil sample during the sampling process. Compared to existing technologies, this device better preserves the undisturbed state and water stability of the soil sample, providing a reliable sample for subsequent detection of water-stable large aggregates.
