Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of soil sampling, and in particular to a soil sampling device for soil environment monitoring. Background Art

[0002] Soil environmental monitoring is an important means of systematically and periodically evaluating soil environmental quality. Through monitoring, soil pollution problems can be discovered in a timely manner, providing a scientific basis for environmental protection departments to formulate effective soil pollution prevention and control and remediation measures. At the same time, soil environmental monitoring is also an important cornerstone for ensuring the safety of agricultural products, maintaining ecological balance and promoting sustainable development. However, the traditional sampling method relies on the motor to drive the entire sampling device to move vertically. This design not only leads to a lengthy sampling process, but also requires multiple lifting and lowering to obtain soil samples at different depths, which increases time and energy consumption. In addition, the sampling tube is prone to residual soil during repeated use. If it is not cleaned in time and thoroughly, it will directly affect the purity and analysis accuracy of subsequent samples, forcing operators to perform additional cleaning steps, which not only increases labor intensity, but also may cause continuous sampling errors due to incomplete cleaning. Therefore, the development of a soil sampling device for soil environmental monitoring that can effectively overcome the defects in the above-mentioned related technologies has become a technical problem that needs to be solved urgently in the industry.

[0035] In the above-mentioned embodiments, a soil sampling device for soil environment monitoring provided in the embodiments of the present invention adopts a relatively strong metal material for soil sampling, and the sampling material (such as cemented carbide, titanium alloy, stainless steel, etc.) can be replaced according to the hardness of the sampled soil. When the device is used, the frame 1 is placed above the soil to be sampled, and the rotating handle 25 is rotated, and the rotating handle 25 drives the first threaded rod 3 to drill into the soil, so that the first threaded rod 3 fixes the entire device. At this time, the pushing device 5 is started, and the pushing device 5 pushes the first pushing plate 6, and the first pushing plate 6 pushes the second pushing plate 8, and the second pushing plate 9 is driven by the first pushing plate 9. The plate 8 drives the sampling tube 11 to slide downward on the slide bar 2, so that the sampling tube 11 is inserted into a suitable position in the soil. At this time, the second motor 10 is started, and the second motor 10 drives the sampling tube 11 to rotate clockwise. The rotation of the sampling tube 11 drives multiple toggle blocks 16 to rotate accordingly. The rotating toggle blocks 16 are squeezed by the soil to push the closing plate 17 to slide in the annular groove 21, thereby opening the closed sampling port 18. At this time, the rotating toggle blocks 16 break the soil, and the broken soil enters the storage tank 24 in the sampling tube 11 through the opened sampling port 18 and falls on the partition 19, thereby realizing the layered collection of soil at different depths;

[0036] When the required amount is extracted, the sampling barrel 11 is rotated counterclockwise to make the sampling barrel 11 drive the toggle block 16 to rotate. The rotating toggle block 16 pushes the closing plate 17 to close the sampling port 18 through the squeezing of the soil. At this time, the pushing device 5 moves upward to make the sampling barrel 11 separate from the soil. When the sample needs to be taken out, the drill bit 14 is rotated to make the drill bit 14 separate from the sampling barrel 11. At this time, the start of the first motor 9 drives the second threaded rod 15 to rotate. The rotation of the second threaded rod 15 causes the partition 19 to slide on the limit rod 20 toward the drill bit 14. The partition 19 drives the soil to separate from the interior of the sampling barrel 11. At this time, the staff can collect soil at different layers. By reversing the second threaded rod 15, the partition 19 is pushed onto the limit rod 20 and meshed with the second threaded rod 15. The partition 19 will move in the direction away from the drill bit 14 inside the sampling barrel 11. In this way, through repeated operations of multiple partitions 19, the partition 19 can be fixed in the original position.

[0037] Continue to see Figure 1-Figure 7Based on the aforementioned embodiments, a first motor 9 is fixedly connected to a side of the first push plate 6 away from the second push plate 8, an output shaft end of the first motor 9 is fixedly connected to the second threaded rod 15, and the second threaded rod 15 is movably connected to the first push plate 6. The start of the first motor 9 drives the second threaded rod 15 to rotate.

[0038] The first push plate 6 is symmetrically fixedly connected to a limiting rod 20 on one side close to the second push plate 8. The limiting rod 20 is slidably connected to the partition 19, the cleaning plate 22 is threadedly connected to the second threaded rod 15, the cleaning plate 22 is slidably connected to the limiting rod 20, the cleaning plate 22 is fixedly connected to the cleaning bristles 23, the cleaning bristles 23 are movably connected to the storage slot 24, and the rotation of the second threaded rod 15 drives the cleaning plate 22 and the cleaning bristles 23 to slide on the limiting rod 20.

[0039] In this embodiment, as described in the previous step, when the partition 19 is completely separated from the interior of the sampling tube 11, the first motor 9 is started to drive the second threaded rod 15 to rotate forward and reverse, so that the cleaning plate 22 moves up and down on the limiting rod 20, so that the cleaning plate 22 drives the cleaning bristles 23 to clean the storage tank 24 in the sampling tube 11. During the movement of the cleaning plate 22 and the cleaning bristles 23, water can be filled into the interior of the sampling tube 11 to improve the cleaning efficiency and effect. The interior of the sampling tube 11 can be cleaned by repeated cleaning of the cleaning plate 22 and the cleaning bristles 23.

[0040] The present invention provides a soil sampling device for soil environment monitoring. The multi-layer sampling assembly realizes synchronous sampling of soil at different depths under one power drive, which greatly shortens the time required for the sampling process and reduces energy consumption. The ingenious combination of the sampling barrel, the toggle block, the partition and the closing plate ensures that the soil sample can accurately fall on the corresponding partition, effectively avoiding cross contamination between samples and ensuring the purity of the sample and the analysis accuracy. On the other hand, the forward and reverse rotation of the second threaded rod in the cleaning assembly allows the cleaning plate to easily move up and down inside the sampling barrel, and the cleaning hairs thereon can penetrate into every corner of the sampling barrel, effectively removing residual soil, avoiding cross contamination between soil samples, and ensuring the accuracy of the next sampling.
