[0002] Soil bulk density is one of the important indicators to measure the soil compaction degree, which directly affects the soil aeration, permeability and plant root growth, etc. In agriculture, horticulture and soil science research, accurate determination of soil bulk density has important practical significance. In order to obtain the value of soil bulk density, a certain amount of soil sample is usually extracted from the soil by a sampler for analysis. The existing soil bulk density sampler is generally made of metal or plastic material, has a cylindrical structure, and is vertically inserted into the soil during operation, then the sampler is removed, and the soil sample in the sampler is taken out for weighing and further processing. However, in practical application, especially in humid or sticky soil, it is a big challenge to take out the soil sample from the sampler.
[0003] In the prior art, the design of the soil sampler is relatively mature, but still has certain defects and deficiencies. Especially for wet soil or sticky soil (such as clay), the soil in the sampler is easy to adhere and not easy to fall off, which makes the process of extracting the soil sample from the sampler very difficult. The traditional sampler design usually lacks effective soil separation device, and the soil sample is often stuck in the cylindrical sampler and cannot be smoothly taken out. Especially in wet or sticky soil, the adhesion between the soil sample and the sampler is large, and the traditional manual operation cannot effectively solve this problem, often needs to be forcibly taken out by knocking, vibrating or other auxiliary means, which not only increases the operation difficulty, but also may cause the damage or shape change of the soil sample, affecting the measurement accuracy of the soil bulk density.
[0004] In addition, the design of the existing soil sampler is mostly a simple cylindrical structure, which does not consider the need for the soil sample to smoothly fall off from the sampler. Although some samplers are provided with exhaust holes or drainage holes, these designs are only effective under certain conditions and cannot effectively solve the problem of extracting the soil sample in sticky or wet soil.

[0023] EMBODIMENT
[0024] The following will be combined Figure 1 And Figure 2 Introduce an easy sampling soil bulk density sampler provided by the application, which is simple and practical in design, can effectively solve the problem of difficult soil sampling in wet or clay soil, and ensure the accuracy of soil bulk density measurement. The specific implementation is as follows:
[0025] 1. Structural Design
[0026] The basic structure of this soil bulk density sampler includes components such as a cylinder 1, a cylinder cover 2, an installation tube 3, a handle 4, a threaded sleeve 5, a threaded rod 6, and a push plate 7. The cylinder 1 is a hollow cylinder with an open end for inserting soil samples and an installation tube 3 at the other end. The outer wall of the cylinder 1 is also equipped with an observation window 15 and an exhaust vent for observing the sampling process and ensuring air circulation.
[0027] Cylinder 1: Cylinder 1 is a hollow cylinder with a smooth inner wall, facilitating the sliding of soil samples. The open end of cylinder 1 has a conical transition 9 to facilitate quick engagement between the cap 2 and cylinder 1. The outer wall of cylinder 1 has a circumferentially circumferentially provided barb groove 8. The embedded barb 13 on the cap 2 can easily match the barb groove 8, and the elastic element 14 ensures a tight fit of the cap 2 during operation.
[0028] Cylinder cover 2: The cylinder cover 2 is connected to the open end of the cylinder body 1 through a barb groove 8 and an embedded barb 13. This connection method allows the cylinder cover 2 to firmly cover the open end of the cylinder body 1, preventing soil leakage during sampling. At the same time, the elastic element 14 provides a certain thrust to ensure the sealing between the cylinder cover 2 and the cylinder body 1.
[0029] Installation tube 3 and handle 4: An installation tube 3 is concentrically installed at the end of the cylinder 1 furthest from the open end. Both ends of the installation tube 3 are open and connected to the cylinder 1. A handle 4 is rotatably installed on the installation tube 3, and a threaded sleeve 5 is provided on the handle 4 that extends into the installation tube 3. The circumferential surface of the handle 4 has a hand groove 12 parallel to the axis of the handle 4 to increase the gripping force. The threaded sleeve 5 and the threaded rod 6 are connected by threads. When the handle 4 is rotated, the threaded rod 6 pushes the soil sample smoothly out of the cylinder 1 through the push plate 7. The push plate 7 can also be pushed to a preset position by rotating the handle 4 to control the sampling depth.
[0030] Push plate 7: The end of the threaded rod 6 is provided with a push plate 7. The structural design of the push plate 7 ensures that it can fit tightly against the inner wall of the cylinder 1, thereby effectively pushing the soil sample and preventing the soil sample from getting stuck in the cylinder 1. The material and shape design of the push plate 7 can reduce damage to the soil sample during the pushing process and maintain the integrity of the soil sample.
[0031] 2. Operating Procedures
[0032] Sampling preparation: Insert the open end of cylinder 1 into the soil to be sampled, ensuring that the sampler is inserted vertically into the soil and reaches the predetermined depth.
[0033] Sealing the sampler: After inserting it into the soil, the cap 2 is rotated to seal it to the open end of the cylinder 1. At this time, the soil sample inside the cylinder 1 is completely sealed inside the sampler.
[0034] Soil sample extraction: Rotating the mounting tube 3 via the handle 4 causes the threaded rod 6 to push the push plate 7. The push plate 7, pressed tightly against the inner wall of the cylinder 1, pushes the soil sample out of the cylinder 1. The design of the push plate 7 prevents the soil sample from adhering to the cylinder wall, ensuring smooth detachment of the soil sample.
[0035] Observation and Calibration: During soil sample extraction, the condition of the soil sample can be observed through the transparent observation window 15 on the cylinder 1. Simultaneously, the bubble level 10 can be used to ensure the verticality of the sampler, avoiding errors caused by sampler tilting.
[0036] 3. Preferred Implementation Method
[0037] Conical transition 9 design: The outer wall of the opening end of the cylinder 1 is provided with a conical transition 9, which helps the cylinder cover 2 to be inserted and sealed, and avoids jamming and air leakage.
[0038] The barbed groove 8 and the elastic element 14: The design of the barbed groove 8 and the elastic element 14 enhances the fit between the cap 2 and the body 1, improves the sealing performance, and enables the cap 2 to be firmly fixed on the body 1, preventing it from loosening during carrying.
[0039] Transparent observation window 15 and scale 16: The transparent observation window 15 facilitates observation of the soil sample's condition inside the tube during the sampling process, while the scale 16 can be used to record the soil sample's depth and location, ensuring accurate sampling.
[0040] Air guide hole 11 design: The air guide hole 11 on the cylinder 1 away from the opening end can prevent negative pressure from forming during the sampling process and avoid operational difficulties caused by poor air circulation.
[0041] In summary, the easy-to-sampling soil bulk density sampler of the present invention has the advantages of simple operation, smooth sampling, high efficiency, and high accuracy, making it an ideal tool for measuring soil bulk density, especially suitable for sampling moist or clayey soils. Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 invention should be included within the protection scope of the present invention.
