[0024] Please see Figures 1-5 A soil sample storage box for preventing cross-contamination includes a storage box body 1, with multiple partition boxes 2 inside the storage box body 1 and multiple placement cavities 101 inside the storage box body 1. Each placement cavity 101 contains a sponge pad 102. The partition boxes 2 are located inside the placement cavities 101. The multiple placement cavities 101 allow for separate placement of the partition boxes 2, preventing breakage of the partition boxes 2 due to shaking inside the storage box body 1. The sponge pads 102 also provide cushioning protection for the partition boxes 2 inside the placement cavities 101. Furthermore, each partition box 2 contains soil samples from different locations and times, preventing the possibility of cross-contamination between soil samples.

[0025] like Figure 3 , Figure 4 and Figure 5 As shown, the separator box 2 includes a screening box 201 and a material holding box 4, which are threaded together. The screening box 201 can crush the soil. A sealing cover 202 is provided on the top of the screening box 201. A protective cover 203 is fixedly connected to the upper side of the sealing cover 202. A rope winding rod 207 is rotatably connected inside the protective cover 203. A crushing rod 205 is fixedly connected to the lower side of the rope winding rod 207. The crushing rod 205 passes through the sealing cover 202 and extends into the screening box 201. A roller is provided at the connection between the crushing rod 205 and the sealing cover 202. A spring 206 is installed on the top side of the inner wall of the rope winding rod 207 and the protective cover 203. A pull rope 204 is wound on the rope winding rod 207. The pull rope 204 passes through the protective cover 203 and extends to the outside. A screening plate 208 is installed on the bottom side of the screening box 201.

[0026] When soil needs to be crushed, the pull rope 204 can be pulled. When the pull rope 204 is pulled, it drives the winding rod 207 to rotate. When the winding rod 207 rotates, it drives the crushing rod 205 to rotate. At this time, the coiled spring 206 is also in the unfolded state. When the crushing rod 205 rotates, the blades on the crushing rod 205 crush the soil, turning the coagulated large soil particles into small particles, which can fall into the collection box 4 through the screening plate 208. When the winding rod 207 stops being pulled, under the action of elastic potential energy, the spring 206 will return to its initial state, thereby driving the winding rod 207 to rotate in the opposite direction, which in turn plays a role in winding the winding rod 207. The pull rope 204 is wound back onto the winding rod 207. At this time, the crushing rod 205 will also crush the soil in the opposite direction. This process is repeated to complete the crushing and screening of the soil.

[0027] Furthermore, the material container 4 is equipped with a label that records the soil collection time, location, temperature, weather, and information of the collector, facilitating subsequent traceability.

[0028] Specifically, a plug-in block 3 is fixedly connected to the upper side of the screening box 201, and a plug-in groove 302 is provided on the sealing cover 202. Both the sealing cover 202 and the screening box 201 have threaded holes 301, and a threaded rod 303 is threadedly connected inside the threaded holes 301. A rubber ring 401 is fitted at the connection between the material container 4 and the screening box 201. To prevent the sealing cover 202 from rotating when the pull rope 204 is pulled, a plug-in block 3 and a plug-in groove 302 are designed. When the plug-in block 3 is inserted into the plug-in groove... When inside 302, the rotation angle of the sealing cover 202 is limited. When the worker holds the screening box 201 and then pulls the rope 204, the sealing cover 202 will not shift at an angle. After the soil collection is completed, the threaded rod 303 is rotated to connect the sealing cover 202 with the screening box 201. Then, the rubber ring 401 is fitted onto the connection between the material box 4 and the screening box 201. This setting can play a sealing role and prevent soil from leaking from the material box 4 and the screening box 201.

[0029] Working principle: During use, the collected soil is placed inside the screening box 201, and then the sealing cover 202 is closed. When the pull rope 204 is pulled, it drives the winding rod 207 to rotate. The rotation of the winding rod 207 drives the crushing rod 205 to rotate, which also causes the coiled spring 206 to unfold. When the crushing rod 205 rotates, the blades on it break up the soil, turning large, coarse soil particles into smaller particles that can then pass through the screening plate 208 and fall into the collection box 4. When the winding rod 207 stops pulling, the spring 206 will return to its initial state under the action of elastic potential energy, thereby driving the winding rod 207 to rotate in the opposite direction, which in turn plays a role in winding the winding rod 207. The pull rope 204 will then wind back onto the winding rod 207. At this time, the crushing rod 205 will also crush the soil in the opposite direction. This process is repeated to complete the crushing and screening of the soil. Each partition box 2 contains soil from different locations and times, avoiding the possibility of cross-contamination between soils.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
