Description

Technical Field

[0001] This application relates to the field of soil sampling technology, and in particular to a biological crust soil sampling device. Background Technology

[0002] Biocrusts, also known as biological soil crusts or soil microbial crusts, are an important type of land cover in arid and semi-arid regions such as deserts, with a coverage rate of over 40%, and are one of the most distinctive biological landscapes in these areas. For research and production purposes, soil sampling devices are typically used to collect soil samples from designated areas, which are then processed and analyzed.

[0003] Existing soil sampling devices include a perforated plate with a soil sampling drill connected to its inner wall. A horizontal plate, a bonding plate, and a conical plate ensure a stable connection between the outer wall of the drill and the ground, preventing accidental contact that could cause the drill to separate from the loose soil and facilitating better soil sampling. A ring, a sliding plate, and a fixing block ensure a secure embedding of the conical plate into the soil, preventing the connecting rod from shaking and causing the conical plate to separate from the ground, thus effectively improving the device's ability to limit the drill's position.

[0004] In the process of developing this application, the inventors discovered the following problem in the technology: after the device is used, soil is easily left on its inner wall, making it inconvenient to clean. This makes it easy to interfere with the sampling of samples and affect the test results when used in subsequent applications, so it needs to be improved. Utility Model Content

[0027] After sampling, the soil adhering to the inner wall of the sampling tube needs to be cleaned. Press the two No. 1 pressing plates to make the sliding rod slide down along the outside of the connecting column. The sliding rod drives the shovel to slide up and down inside the sampling tube through the connecting rod. The conical groove design at the bottom of the shovel helps to shovel and clean the soil more effectively. After cleaning, the sliding rod can be fixed to the locking block with the retaining ring to prevent it from sliding freely.

The cleaning mechanism allows the soil on the inner wall of the sampling tube to be easily cleaned with a shovel, avoiding the tedious manual cleaning process required in traditional sampling methods and ensuring the accuracy of subsequent sampling results. At the same time, the design of the pins and connecting blocks can firmly fix the device to the soil surface, preventing slippage or tilting during sampling. Attached Figure Description

A connecting column 9 is installed on the top plate 1, with its bottom sliding through the top of the top plate 1 and fixedly connected to the top of the sampling cylinder 5. A second pressing plate 14 is installed on the connecting column 9, with its bottom fixedly connected to the top of the connecting column 9. A fixing mechanism is provided on the top plate 1 for fixing the device body. A cleaning mechanism is also provided on the top plate 1 for cleaning the inside of the sampling cylinder 5.

[0037] The sampling cylinder 5 is supported by a fixing mechanism and the second pressing plate 14 can be pressed to drive the sampling cylinder 5 to move up and down, thereby completing the soil sampling. After sampling, the inside is scraped and cleaned by the shovel plate 15.

[0038] Reference Figure 3 and Figure 4 The cleaning mechanism includes two pressing plates 10, two sliding rods 16, two connecting rods 8, and a shovel plate 15. The sides of the two pressing plates 10 that are close to each other are fixedly connected to the sides of the two sliding rods 16 that are far apart. The sides of the two sliding rods 16 that are close to each other are slidably connected to the outside of the same connecting column 9. The tops of the two connecting rods 8 are fixedly connected to the bottoms of the two sliding rods 16. The bottoms of the two connecting rods 8 slide through the top of the top plate 1 and the top of the sampling cylinder 5 and are fixedly connected to the top of the shovel plate 15. The bottom of the shovel plate 15 has a conical groove for easy shoveling. The shovel plate 15 is located inside the sampling cylinder 5.

[0039] When it is necessary to clean the sampling cylinder 5, the first pressing plate 10 can be pressed, and the sliding rod 16 and connecting rod 8 can drive the shovel plate 15 to slide up and down inside the sampling cylinder 5, thereby cleaning the inner wall of the sampling cylinder 5.

[0040] Reference Figure 1 and Figure 2The fixing mechanism includes two side plates 2, two connecting blocks 3 and two pins 4. The side of the two side plates 2 that are close to each other is fixedly connected to the two sides of the same top plate 1. The side of the two side plates 2 that are close to each other is slidably connected to the two sides of the same sampling cylinder 5. The side of the two side plates 2 that are far apart from each other is fixedly connected to the side of the two connecting blocks 3 that are close to each other. Both connecting blocks 3 have round holes. The two pins 4 slide through the two round holes and are inserted into the plane.

[0041] When it is necessary to fix the device to the ground, the bottom of the side plate 2 can be placed close to the ground for support, and then the pins 4 can be inserted into the ground to fix the device.

[0042] Reference Figure 2 and Figure 3 To improve the stability of sliding, both sides of the sampling cylinder 5 are fixedly connected with sliders 13 that facilitate sliding. The two side plates 2 are provided with grooves 7 that are adapted to the sliders 13 on the side that are close to each other. The two sliders 13 are slidably connected to the two grooves 7 respectively to ensure the stable movement of the sampling cylinder 5 during sampling.

[0043] Reference Figure 5 The top of each of the two sliding rods 16 is rotatably connected with a retaining ring 17 for fixing the sliding rod 16. Both sides of the second pressing plate 14 are fixedly connected with a locking block 19 that fits with the retaining ring 17. The two retaining rings 17 are respectively sleeved on the two locking blocks 19.

[0044] When it is not necessary to clean the sampling cylinder 5, the sliding rod 16 can be fixed to the locking block 19 by the retaining ring 17 to prevent the sliding rod 16 from sliding freely.

[0045] Reference Figure 1 and Figure 5 To facilitate pressing, the tops of the two pressing plates 10 and 14 are respectively fixed with pressing pads 11 and 12. The materials of pressing pads 11 and 12 are both rubber. The rubber material of pressing pads 11 and 12 can increase friction and improve pressing comfort.

[0046] Reference Figure 1 and Figure 3 The bottom of the sampling tube 5 is fixedly connected to a conical ring 6, which facilitates the sampling of soil samples. The bottom of the conical ring 6 is designed with an annular blade for easy insertion into the flat surface. This design makes it easier for the sampling tube 5 to be inserted into the soil, and the annular blade ensures the accuracy of the sampling.

[0047] Reference Figure 5 Both retaining rings 17 have a push block 18 fixedly connected to their tops to facilitate pushing the retaining rings 17 open. Both push blocks 18 are arc-shaped.

[0048] When it is necessary to open the retaining ring 17, the retaining ring 17 can be easily pushed off the retaining block 19 by pushing the block 18, thereby facilitating the sliding of the sliding rod 16.

[0049] A conical ring 6 is fixedly connected to the bottom of the sampling cylinder 5, and the bottom of the conical ring 6 is set with an annular knife edge.

[0050] The implementation principle of the biological crust soil sampling device in this application embodiment is as follows: Before sampling, the device needs to be fixed on the soil surface. The side plate 2 is placed on a flat surface for support, and the pin 4 is inserted into the round hole on the connecting block 3, penetrating the soil surface to fix the device. The position of the sampling cylinder 5 can be adjusted by sliding the groove 7 on the side plate 2 to the sliders 13 on both sides of the sampling cylinder 5. Pressing down the second pressing plate 14 drives the sampling cylinder 5 to move downward through the connecting column 9 until the annular blade of the conical ring 6 is inserted into the soil. After sampling, the soil adhering to the inner wall of the sampling cylinder 5 needs to be cleaned. Pressing down the two first pressing plates 10 causes the sliding rod 16 to slide downward along the outside of the connecting column 9. The sliding rod 16 drives the shovel plate 15 to slide up and down inside the sampling cylinder 5 through the connecting rod 8. The conical groove design at the bottom of the shovel plate 15 helps to more effectively shovel and clean the soil. After cleaning, the sliding rod 16 can be fixed to the locking block 19 by the locking ring 17 to prevent it from sliding freely.

[0051] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
