Technical Field

[0001] This utility model relates to the field of soil sampling technology, and in particular to a soil extraction device. Background Technology

[0002] Soil extraction devices, also commonly known as soil samplers, are tools or equipment specifically designed to collect samples from soil. These devices play a crucial role in various fields such as soil analysis, environmental monitoring, geological surveys, and agricultural research. They help researchers, environmental experts, geologists, and farmers obtain representative soil samples for subsequent laboratory analysis, soil quality assessment, environmental pollution monitoring, and crop cultivation guidance.

[0003] Existing soil extraction devices typically require manual removal of the soil from the sampling tube after sampling, which increases the time the soil remains in the tube, increasing the risk of soil contamination and compromising the purity of the soil sample.

[0004] Therefore, it is necessary to propose a soil extraction device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a soil extraction device to solve the problem that, after sampling, soil usually needs to be manually removed from the sampling tube, which increases the residence time of the soil in the sampling tube, poses a risk of soil contamination, and compromises the purity of the soil sample.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a soil extraction device, comprising a sampling rod, a sampling tube fixedly connected to the bottom end of the sampling rod, a push plate movably disposed inside the sampling tube, and a plurality of scrapers fixedly connected in a ring shape to the bottom surface of the push plate;

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. In this utility model, through the cooperation of the components, the push plate can quickly move the soil to the sampling box, eliminating the need for manual removal of the extracted soil, reducing the time the soil stays in the sampling tube, avoiding soil contamination from the inside of the device, and ensuring the purity of the soil sample.

[0016] 2. In this utility model, the scraper can efficiently scrape the soil adhering to the inner wall of the sampling tube during the movement and rotation process, ensuring that the soil sample is completely collected.

[0024] This invention addresses the problem that, typically, after sampling, soil needs to be manually removed from the sampling tube, increasing the soil's residence time in the tube, posing a risk of soil contamination, and compromising the purity of the soil sample. It provides a solution such as... Figures 1-3 The soil extraction device shown includes a sampling rod 1, a sampling tube 2 fixedly connected to the bottom end of the sampling rod 1, a push plate 21 movably disposed inside the sampling tube 2, and multiple scrapers 22 fixedly connected in a ring shape on the bottom surface of the push plate 21. The scrapers 22 are arc-shaped plates, and the tips of the scrapers 22 are in movable contact with the inner wall of the sampling tube 2. When soil sampling is performed, the push plate 21 and the scrapers 22 are located at the top surface inside the sampling tube 2. The sampling rod 1 and the sampling tube 2 are brought to the sampling location, and the sampling rod 1 and the sampling tube 2 are pressed down, so that the sampling tube 2 contacts the ground and extracts the soil.

[0025] It should be noted that a transparent sampling observation window can be installed on one side of the sampling tube 2, which is a mature technology in the prior art. It is not shown in the figure and will not be described in detail here.

[0026] In this utility model, a sliding plate 31 is slidably arranged inside the connecting rod 33, and a through groove 36 is opened at the top of the sampling rod 1. A push rod motor 3 is fixedly connected inside the through groove 36. The end of the push rod on the push rod motor 3 passes through the cylindrical groove 32 and is fixedly connected to the top surface of the sliding plate 31. The bottom surface of the sliding plate 31 is rotatably connected to the top of the connecting rod 33. When in use, the push rod motor 3 is turned on, and the push rod motor 3 drives the sliding plate 31 to move through the push rod. The movement of the sliding plate 31 drives the connecting rod 33 to move. During the movement, the top of the connecting rod 33 rotates on the sliding plate 31.

[0027] It should be noted that the sampling rod 1 has a cylindrical groove 32 inside, and a connecting rod 33 is installed inside the cylindrical groove 32. The connecting rod 33 has a threaded groove 34 on its outer periphery. A cylindrical rod 35 is fixedly connected to one side of the bottom of the cylindrical groove 32. The cylindrical rod 35 is movably connected to the threaded groove 34. During the downward movement of the connecting rod 33, the cylindrical rod 35 causes the connecting rod 33 to rotate along the path of the threaded groove 34, so that the connecting rod 33 rotates while moving downward.

[0028] It should also be noted that the contact section between the cylindrical rod 35 and the threaded groove 34 is arc-shaped, which facilitates the normal operation of the component.

[0029] The bottom end of the connecting rod 33 passes through the sampling tube 2 and is fixedly connected to the top surface of the push plate 21; as the connecting rod 33 moves downward and rotates, it drives the push plate 21 to move and rotate as well, thereby completing the subsequent work.

[0030] In this invention, after soil sampling is completed, when the soil needs to be placed into the sampling box, the push plate 21 is moved. The push plate 21 moves and rotates at the same time, which drives the scraper 22 on it to move and rotate at the same time. During the rotation of the scraper 22, it scrapes the inner wall of the sampling tube 2. Through the cooperation of the components, the push plate 21 can quickly move the soil into the sampling box without the need for manual removal of the extracted soil. This reduces the time the soil stays in the sampling tube 2, avoids soil contamination from the inside of the device, and ensures the purity of the soil sample.

[0031] Furthermore, during its movement and rotation, the scraper 22 can efficiently scrape the soil adhering to the inner wall of the sampling tube, ensuring that the soil sample is collected completely. The rotation and downward movement of the scraper 22 helps to thoroughly remove soil residue from the inner wall of the sampling tube 2, reducing soil residue and improving the accuracy of soil sampling.

[0032] Furthermore, the combined use of the push plate 21 and the scraper 22 ensures that no soil remains inside the sampling tube 2, avoiding cross-contamination between different soil samples. After the work is completed, the staff does not need to use additional tools to clean the inside of the sampling tube 2. The cleaning is completed during the soil sample removal process, saving time and effort and improving the overall work efficiency.

[0033] In this invention, a mounting frame 11 is movably sleeved around the sampling rod 1, and tapered rods 12 are fixedly connected to the bottom surfaces on both sides of the mounting frame 11. When extracting soil, the sampling tube 2 is placed at the extraction location, and then the mounting frame 11 and tapered rods 12 are pressed down. After the tapered rods 12 are inserted into the ground, the entire device can extract soil in the vertical direction, ensuring the accuracy of soil sampling.

[0034] It should be noted that a handle 13 is fixedly connected to the top of the sampling rod 1; when extracting soil, the handle 13 is rotated, and the rotation of the handle 13 drives the sampling rod 1 and the sampling tube 2 to rotate. Through the power of rotation, the sampling tube 2 enters the extraction location to complete the extraction.
