Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, specifically to a soil sampling sampler. Background Technology

[0002] Soil samplers are core tools in environmental monitoring, agricultural production surveys, and geological exploration. They are mainly used to obtain soil samples from different depths and areas, providing basic samples for soil composition analysis, fertility assessment, and pollution detection. They typically consist of a gripping component, a sampling tube, and an operating mechanism. The core requirements are easy insertion into the soil, ensuring sample integrity, and facilitating subsequent sample retrieval. The ease of operation and component compatibility of the sampler directly affect sampling efficiency and the accuracy of sample testing.

[0003] Existing soil sampling samplers have a fixed grip structure, which makes it difficult to find a comfortable angle for application, increasing the difficulty of insertion into the soil, or it takes up a lot of space and is inconvenient to carry due to its non-adjustable structure. Disassembling and assembling the sampling tube requires additional tools such as wrenches, which are easily lost or misplaced, making it impossible to change to different sizes of sampling tubes in time during on-site sampling, interrupting the work process. At the same time, after sampling, the soil tends to stick tightly to the inner wall of the sampling tube, requiring tools to knock or dig to remove it. This is not only cumbersome but also easily damages the original structure of the soil sample, affecting the accuracy of subsequent test data. It is difficult to meet the needs of efficient and accurate soil sampling. Therefore, it is necessary to design a soil sampling sampler. Utility Model Content

[0020] This utility model provides a technical solution: Example

[0021] Combination Figures 1 to 8 A soil sampling device includes a main rod 3, sampling mechanisms 1 are provided on the upper and lower sides of the main rod 3, and a discharge mechanism 2 is provided at the bottom of the sampling mechanism 1.

[0022] The sampling mechanism 1 includes a gripping component 11, a sampling component 12, a locking component 13, and a disassembly component 14.

[0023] The grip assembly 11 includes a frame plate 1101, which is fixedly connected to the top of the front and rear sides of the main rod 3. A fixed shaft 1102 is fixedly connected to the top of the inner side of the frame plate 1101. A grip rod 1103 is rotatably connected to the outer ring of the fixed shaft 1102.

A locking rod 1202 is fixedly connected to the top of the sampling cylinder 1201 and is engaged with the bottom of the main rod 3. A collar 1203 is fixedly connected to the top of the sampling cylinder 1201 and is sleeved on the outer ring of the main rod 3. A reinforcing element is fixedly connected to the outer ring of the collar 1203. Fin 1204 is fixedly connected to the top of sampling cylinder 1201. Locking assembly 13 includes fixing seat 1301, which is fixedly connected to the right side of main rod 3 at the position corresponding to clamp rod 1202. Bolt 1302 is clamped in the inner ring of fixing seat 1301 and threadedly connected to clamp rod 1202. Disassembly assembly 14 includes threaded block 1401, which is threadedly connected to the left side of handle 1103. L-shaped hexagonal wrench 1402 is fixedly connected to the right side of threaded block 1401 and is located inside the left side of handle 1103. Torsion plate 1403 is fixedly connected to the left side of threaded block 1401.

[0024] Furthermore, when using this device, the operator can adjust the horizontal and vertical position of the handle 1103 according to the needs of use, making it convenient for the operator to use or store. At the same time, the operator can disassemble and assemble the threaded block 1401 and the L-shaped hex wrench 1402 by rotating the torsion plate 1403, and the operator can adjust the bolt 1302 by using the L-shaped hex wrench 1402. This makes it convenient for the operator to disassemble and assemble the sampling cylinder 1201 and the main rod 3. The operation is simple and easy to use. Example

[0025] See Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 9 Furthermore, based on Embodiment 1, the discharge mechanism 2 includes a discharge component 21 and an adsorption component 22. The discharge component 21 is disposed inside the sampling component 12, and the adsorption component 22 is disposed above the discharge component 21.

[0026] The discharge assembly 21 includes a slide cylinder 2101, which is slidably connected to the inner ring of the sampling cylinder 1201. A limiting slide rod 2102 is fixedly connected to the front side of the slide cylinder 2101. The limiting slide rod 2102 is slidably connected to the inner front side of the sampling cylinder 1201. A fixing plate 2103 is fixedly connected to the front side of the limiting slide rod 2102. A pedal 2104 is fixedly connected to the top of the fixing plate 2103. A reinforcing fin 2105 is fixedly connected to the bottom of the pedal 2104. The reinforcing fin 2105 is fixedly connected to the front side of the fixing plate 2103. The adsorption assembly 22 includes a retaining ring 2201, which is fixedly connected to the top of the sampling cylinder 1201. A magnetic block 2202 is fixedly connected to the inner ring of the retaining ring 2201. A metal block 2203 is provided below the magnetic block 2202. The metal block 2203 is fixedly connected to the top of the slide cylinder 2101.

[0027] Furthermore: After the sampling tube 1201 is inserted into the ground to complete the soil sampling, the staff only needs to step on the pedal 2104 downwards to squeeze the soil in the sampling tube 1201 downwards through the slide tube 2101, making it easy for the staff to take out the sampled soil. The operation is simple and easy for the staff to use.

[0028] In actual operation, when this device is used, the operator first places the sampling cylinder 1201 inside the bottom of the main rod 3, so that the locking rod 1202 is locked inside the bottom of the main rod 3. Then, the operator inserts the bolt 1302 into the inner ring of the fixing seat 1301, and then rotates the bolt 1302. The bolt 1302 rotates and the threaded connection of the bolt 1302 is connected to the inner ring of the locking rod 1202. At this time, the operator has completed the installation of the sampling cylinder 1201. Then, the operator moves the pedal 2104 upward, so that the metal block 2203 moves upward and contacts the limiting slide bar 2102. At this time, the metal block 2203 is attracted by the magnetic block 2202, fixing the position of the slide bar 2101 inside the top of the sampling cylinder 1201. Next, the staff flips the handle 1103 to make it straight, and then inserts the sampling tube 1201 into the ground to allow soil to enter the sampling tube 1201 to complete the soil sampling process. After that, the staff pulls out the sampling tube 1201 and fixes it to the ground at an angle. Then, the staff holds the handle 1103 to keep the sampling tube 1201 from falling down, and at the same time steps on the pedal 2104 downward. The downward movement of the pedal 2104 drives the sliding tube 2101 downward through the fixing plate 2103 and the limiting slide rod 2102. The sliding tube 2101 pushes the soil sampled in the sampling tube 1201 downward and discharges it from the sampling tube 1201. At this time, the collection of the sampled soil is completed.
