Description

Technical Field

[0001] The present invention relates to the technical field of soil sampling, in particular to a soil sampling device for ecological restoration. Background Art

[0002] In environmental governance, soil remediation is an important part. For soil remediation, it is necessary to first investigate the soil conditions. The usual investigation method is to take stratified samples at different depths of the soil, and perform component analysis based on the sampled samples to determine the specific conditions of the soil and formulate a remediation strategy based on the conditions.

[0003] Current deep soil sampling devices suffer from numerous drawbacks, particularly their inability to effectively segment and stratify soil samples during the sampling process. In practice, these devices typically only remove relatively large clumps of soil at a time, failing to accurately stratify them as needed. This necessitates manual labor to perform subsequent fine segmentation and stratification when obtaining deep soil samples. This not only adds additional workload but also easily leads to sample loss or contamination, increasing uncertainty and the risk of detection error, significantly impacting the overall efficiency of soil testing.

The four corners of the bottom of the top mounting plate are fixedly mounted with support rods, and the four corners of the limit slide 1 and the limit slide 2 are fixedly mounted on the outside of the support rods. The sampling outer cylinder is slidably mounted inside the limit slide 1 and the limit slide 2, and a pin assembly is installed on the top of the limit slide 2.

Two movable grooves 27 are symmetrically provided inside the rotating block 21. The outer sides of the tops and bottoms of the multiple rotating blocks 21 are rotatably installed with limit rings 20. The positions of the multiple limit rings 20 correspond to the positions of the multiple arc-shaped through grooves 24 respectively. The outer sides of the tops and bottoms of the rotating rods 29 are rotatably installed on the outer sides of the limit rings 20. The sliding rod 30 is movably installed on the inner side of the movable groove 27. The top of the rotating shaft 19 is fixedly installed with a hand-turning block 9. The interior of the hand-turning block 9 is symmetrically provided with two locking holes 26. The top of the sampling outer cylinder 1 is provided with four locking holes 25, and the four locking holes 25 are divided into two groups. The interiors of the locking holes 26 are slidably installed with locking rods 18, and the top of the locking rod 18 is fixedly installed with a locking plate 8.

[0026] The working principle of the above technical solution is: when sampling is required, the device can be moved to the required position, and then the sampling outer cylinder 1 only needs to be rotated, and the inner drill cylinder 23 is driven to rotate, and the rotating sampling outer cylinder 1 and the inner drill cylinder 23 can be made to enter the ground through the pointed cone block 15 at the bottom of the sampling outer cylinder 1 and the drill bit 16 at the bottom of the inner drill cylinder 23, so that a soil ring is formed between the sampling outer cylinder 1 and the inner drill cylinder 23, and then the rotation of the sampling outer cylinder 1 is stopped, and the hand-turned block 9 is manually rotated to drive the rotating shaft 19 to rotate, thereby driving the rotating block 21 to rotate, and then the sliding rod 30 is driven to move through the moving groove 27, thereby driving the rotating rod 29 to rotate through the moving block 22, driving the dividing knife 28 to rotate, so that the dividing knife 28 is disengaged from the inside of the arc-shaped through groove 24, and the dividing knife 28 is cut into the soil ring inside the sampling outer cylinder 1 and the inner drill cylinder 23, and then the locking rod 18 at the bottom of the locking plate 8 can be locked. Inserted into the inside of locking hole 26 and locking hole 1 25, the hand-turning block 9 and the rotating shaft 19 are locked, and then the sampling outer cylinder 1 is rotated again, thereby driving the separating knife 28 to rotate, and the soil ring between the sampling outer cylinder 1 and the inner drill cylinder 23 is cut, which can accurately separate and sample the soil at different depths, greatly improving the sampling effect, and can obtain more comprehensive and accurate soil sample information, which is of vital importance for subsequent soil testing, component analysis and environmental assessment. It can more deeply understand soil characteristics, evaluate soil quality and predict environmental change trends, and then stop rotating the sampling outer cylinder 1. The separating knife 28 can also support the soil ring between the sampling outer cylinder 1 and the inner drill cylinder 23. When the sampling outer cylinder 1 is pulled upward, the separating knife 28 can push the soil ring upward, thereby facilitating the removal of the soil ring, making the entire removal process smoother and more efficient.

The four corners of the bottom of the top mounting plate 6 are fixedly mounted with support rods 7, and the four corners of the limit slide 1 31 and the limit slide 2 32 are fixedly mounted on the outside of the support rod 7. The sampling outer cylinder 1 is slidably mounted on the inside of the limit slide 1 31 and the limit slide 2 32, and a pin assembly is installed on the top of the limit slide 2 32. The pin assembly includes four inner sleeve rods 14, and the outer sides of the four inner sleeve rods 14 are slidably mounted with a movable plate 10, and the bottom of the movable plate 10 is fixedly mounted with a movable rod 11, and the bottom of the movable rod 11 is fixedly mounted with a pedal 12, and the bottom of the pedal 12 is fixedly mounted with a pin 13. The four inner sleeve rods 14 are respectively fixedly mounted on the four corners of the top of the limit slide 2 32, and the four movable plates 10 are respectively slidably mounted on the outsides of the four support rods 7.

[0028] The sampling outer cylinder 1 can be installed in the required position through the support and limit assembly. The staff only needs to step on the pedal 12, and the moving plate 10 is driven by the moving rod 11 to slide on the outside of the support rod 7 and the inner sleeve rod 14, so that the pin 13 is plugged into the ground, thereby installing the device in the required position, providing a solid guarantee for subsequent sampling operations. After that, the sampling outer cylinder 1 can be pushed to move downward on the inner side of the limit slide 1 31 and the limit slide 2 32, effectively reducing the vibration and impact generated during the sampling process, and ensuring the accuracy and reliability of the sampling results.

[0029] In another embodiment, Figure 1-Figure 7 As shown, a driving motor 5 is fixedly installed on the top of the top mounting plate 6, and the output end of the driving motor 5 movably passes through the top mounting plate 6 and is fixedly installed with a rotating plate 17. The four corners of the bottom of the rotating plate 17 are fixedly installed with telescopic rods 4, and the bottom of the telescopic rod 4 is fixedly connected to the top of the sampling outer cylinder 1. A bearing ring 2 is fixedly installed on the outside of the sampling outer cylinder 1, and four hand-held rods 3 are fixedly installed on the outside of the bearing ring 2.

[0030] After the driving motor 5 is started, the four telescopic rods 4 can be driven to rotate through the rotating plate 17, thereby driving the sampling outer cylinder 1 to rotate. In addition, the bearing ring 2 and the four hand-held rods 3 can be set to press the sampling outer cylinder 1 downward when the sampling outer cylinder 1 rotates, so that the sampling outer cylinder 1 and the inner drill cylinder 23 can be inserted into the ground, which is convenient for subsequent soil sampling.

[0031] Working principle: When sampling is required, the device can be moved to the required position, and the sampling outer cylinder 1 can be installed in the required position through the support limit assembly. The staff only needs to step on the pedal 12, and the moving rod 11 drives the moving plate 10 to slide on the outside of the support rod 7 and the inner sleeve rod 14, so that the pin 13 is plugged into the ground, thereby installing the device in the required position, providing a solid guarantee for the subsequent sampling operation, and then the sampling outer cylinder 1 can be pushed to move downward on the inside of the limit slide 1 31 and the limit slide 2 32, which effectively reduces the vibration and impact generated during the sampling process, ensures the accuracy and reliability of the sampling results, and drives After the motor 5 is started, the four telescopic rods 4 can be driven to rotate through the rotating plate 17, thereby driving the sampling outer cylinder 1 to rotate and driving the inner drill cylinder 23 to rotate. In addition, the bearing ring 2 and the four hand-held rods 3 can be used to press the sampling outer cylinder 1 downward when the sampling outer cylinder 1 rotates. The pointed cone block 15 at the bottom of the sampling outer cylinder 1 and the drill bit 16 at the bottom of the inner drill cylinder 23 can make the rotating sampling outer cylinder 1 and the inner drill cylinder 23 enter the ground, so that a soil ring is formed between the sampling outer cylinder 1 and the inner drill cylinder 23. After that, the rotation of the sampling outer cylinder 1 is stopped, and the hand-turning block 9 is manually turned to drive the rotating shaft 19 to rotate, thereby driving the rotating block 21 to rotate. The sliding rod 30 is then driven to move through the moving groove 27, thereby driving the rotating rod 29 to rotate through the moving block 22, driving the dividing knife 28 to rotate, so that the dividing knife 28 is disengaged from the inside of the arc-shaped through groove 24, and the dividing knife 28 is cut into the soil ring inside the sampling outer cylinder 1 and the inner drill cylinder 23. After that, the locking rod 18 at the bottom of the locking plate 8 can be inserted into the inside of the locking hole 26 and the locking hole 1 25, and the hand-turning block 9 and the rotating shaft 19 are locked. Then, the sampling outer cylinder 1 is rotated again, thereby driving the hand-turning block 9 and the dividing knife 28 to rotate, and the soil ring between the sampling outer cylinder 1 and the inner drill cylinder 23 is cut. The sampling effect is greatly improved by accurately separating and sampling the soil at different depths, and more comprehensive and accurate soil sample information can be obtained, which is of vital importance for subsequent soil testing, component analysis, and environmental assessment. It can provide a deeper understanding of soil characteristics, evaluate soil quality, and predict environmental change trends. Then stop rotating the sampling outer cylinder 1. The separating knife 28 can also support the soil ring between the sampling outer cylinder 1 and the inner drill cylinder 23. When the sampling outer cylinder 1 is pulled upward, the separating knife 28 can push the soil ring upward, thereby facilitating the removal of the soil ring, making the entire removal process smoother and more efficient.
