[0002] In hydrogeological surveys, soil sampling tools are indispensable key equipment. By accurately sampling soil at different depths and in different areas, they can provide original samples for subsequent soil composition testing and physicochemical property analysis, thereby scientifically determining the soil quality status and providing important data support for groundwater protection, geological environment assessment, and other work.

[0003] Existing layered soil sampling tools require various replaceable accessories (such as sampling plugs) during use. These accessories are consumable parts and need to be replaced in time after a period of use. However, in the current tool design, each set of soil sampling tools usually only comes with one sampling plug. The spare plug is not fixedly associated with the main body of the tool and needs to be stored separately by the user. This is not only easy to lose, but also brings a lot of inconvenience to carrying in the field and affects the efficiency of operation. Summary of the Invention

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please refer to Figures 1 to 5 Example 1:

[0028] This utility model proposes a convenient layered soil sampling tool for hydrogeological surveys, comprising: a sampling tube 1, with a layered sleeve 101 inserted inside the sampling tube 1. The layered sleeve 101 is designed to facilitate direct introduction of soil into the layered sleeve 101 during sampling. The layered sleeve 101 is made of transparent plastic. An integrated handle 2 is threaded onto the top of the sampling tube 1, designed to facilitate the insertion of the sampling tube 1 into the soil by the operator. A storage slot A201 is provided on the right end of the integrated handle 2, which can store the dividing blade 203. A knob 204 is fixedly installed on the right end of the locking handle 202, designed to facilitate rotation of the locking handle 202 by the user. A storage slot B205 is provided on the left end of the integrated handle 2, designed to facilitate the storage of a spare sampling head 206 for layered soil sampling. The sleeve 101 is inserted into the sampling tube 1, and then the sampling head 103 is threaded and locked to the bottom end of the sampling tube 1, so that the sampling head 103 restricts the layered sleeve 101 inside the sampling tube 1. Then, the user uses the integrated handle 2 to apply force to insert the sampling tube 1 into the soil. During the insertion process, the soil will be introduced into the interior of the layered sleeve 101, so that the layered sleeve 101 collects the soil in layers. After the collection and sampling are completed, the sampling tube 1 is taken out of the soil, and then the sampling head 103 is loosened to remove the restriction on the layered sleeve 101. At this time, the layered sleeve 101 can be taken out from the interior of the sampling tube 1. After taking it out, the user can rotate the knob handle 204 to make it, along with the locking handle 202 and the dividing blade 203, disengage from the storage groove A201. Then, the user uses the dividing blade 203 to cut the layered sleeve 101 from the dividing groove 102, thereby separating and storing the soil samples taken from different depths.

[0029] In Example 2, based on Example 1, a row of dividing grooves 102 are arranged at equal intervals from top to bottom on the outer wall of the layered sleeve 101. The dividing grooves 102 are designed to facilitate the later cutting of the layered sleeve 101 containing soil samples into multiple segments. A sampling head 103 is threaded onto the bottom end of the sampling tube 1. The sampling head 103 is designed to facilitate the insertion of this sampling tool into the soil. The bottom end of the sampling head 103 has a conical structure. The integrated handle 2 has a T-shaped structure. A locking handle 202 is threaded onto the inside of the storage groove A201. The locking handle 202 is designed to facilitate the installation of the dividing blade 203. By integrating the accessories, the spare sampling head 206 and the dividing blade 203 are stored inside the storage groove structure, so that the accessory structures are all hidden inside the integrated handle 2. When these accessories are needed, they can be taken out from the tool in a timely manner. The accessories are stored together with the tool body, so the accessories are not easy to lose, and the entire tool is easy to carry.

[0030] In Example 3, based on Example 2, a dividing blade 203 is provided at the left end of the locking handle 202. The dividing blade 203 can cut the layered sleeve 101 into multiple segments through the dividing groove 102. A spare sampling head 206 is inserted inside the storage groove B205, which is a substitute for the sampling head 103. A sealing head 207 is threaded on the outer end of the storage groove B205. The sealing head 207 is provided to facilitate the confinement of the spare sampling head 206 inside the storage groove B205. By placing the layered sleeve 101 inside the sampling tube 1, after the sampling tube 1 is inserted into the soil, the soil will be introduced into the layered sleeve 101. After the layered sleeve 101 is removed, it can be segmented by the dividing blade 203 to store soil at different depths separately. The cutting method will not damage the structure of soil samples at different depths, which is convenient for subsequent soil testing.

[0031] Working principle: In use, first, the layered sleeve 101 is fitted into the sampling tube 1, ensuring that the outer wall of the layered sleeve 101 fits snugly against the inner wall of the sampling tube 1. Then, the sampling head 103 is screwed onto the bottom end of the sampling tube 1. The top surface of the sampling head 103 abuts against the bottom surface of the layered sleeve 101, forming an axial limit, which securely confines the layered sleeve 101 within the sampling tube 1, preventing displacement of the sleeve during sampling. During the sampling stage, the operator holds the integrated handle 2 and applies force with their arm to press the sampling tube 1. As the sampling tube 1 sinks into the soil to be sampled, the soil is continuously guided into the layered sleeve 101 by the sampling head 103. Because the inner wall of the layered sleeve 101 is smooth and the contact surface with the soil is treated to prevent adhesion, soil at different depths naturally maintains its original layered state, sequentially filling the interior of the layered sleeve 101, achieving simultaneous collection of multiple soil layers. After sampling is completed, the sampling tube 1 is pulled out of the soil by applying reverse force. At this point, the layered sleeve 101 has completely contained columnar soil samples from different depths. Next... To separate the sampling head 103 from the sampling tube 1, loosen the threaded connection and release the axial restraint on the layered sleeve 101. Then, smoothly extract the layered sleeve 101 from the sampling tube 1 for sample segmentation. The operator rotates the knob 204 on the integrated handle 2, which, through threaded transmission, causes the locking handle 202 to rotate and unlock the dividing blade 203 from the receiving groove A201. At this point, using the sharp edge of the dividing blade 203, align it with the pre-set dividing groove 102 on the outer wall of the layered sleeve 101 (each dividing groove...). 102 corresponds to a preset sampling depth. By smoothly cutting the layered sleeve 101 radially, soil samples at different depths within the layered sleeve 101 can be separated layer by layer for preservation. This ensures that subsequent testing can accurately correspond to the original soil depth information. The entire process, through the pre-installation and limiting of the layered sleeve 101, the layered introduction of soil, and the directional cutting of the samples, not only ensures that the original layered state of the soil samples is not destroyed, but also simplifies the operation process through integrated tool design, improving the efficiency and accuracy of layered sampling.
