Description

Technical Field

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

[0002] Soil sampling refers to the methods of collecting soil samples, including sampling layout and techniques. The selection of sampling points needs to consider factors such as soil type, parent material, topography, natural vegetation, or crops to ensure representativeness. During sampling, the sampling depth is usually determined according to the research objectives, and multiple samples are taken and mixed into a single composite sample to better represent the soil properties of the sampling area.

[0003] Common soil sampling devices are cylindrical structures. The cylinder is rotated to enter the soil, and then the cylinder is pulled out to remove the soil and complete the sampling. However, when the soil is very compacted or contains a lot of water, the cohesion between soil particles increases, making it difficult for the soil to be lifted by the cylinder, thus leading to soil sampling failure. To address this, a deep soil sampling device is proposed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a technical solution: a deep soil sampling device. Please refer to [link / reference needed]. Figure 1 , Figure 2and Figure 3 ,include:

[0025] The base frame 1 and the threaded pipe 4 are provided. The lower end of the base frame 1 is provided with a bottom ring 3, and the threaded pipe 4 and the bottom ring 3 are connected by a threaded engagement.

[0026] Side cavity 12 is located on both sides of the lower end of the threaded tube 4. A transmission gear 14 is provided inside the upper end of the side cavity 12 and is rotatably connected to the threaded tube 4. A clamping plate 15 is provided at the lower end of the transmission gear 14. A drive tooth plate 13 is provided on the side of the transmission gear 14 near the center of the threaded tube 4. The drive tooth plate 13 is slidably connected to the side cavity 12 and the transmission gear 14 is meshed with the drive tooth plate 13.

[0027] Pull rings 10 are provided on both sides of the upper end of the threaded tube 4. A wire rope 11 is provided between the pull rings 10 and the drive tooth plate 13, and the two ends of the wire rope 11 are connected to the pull rings 10 and the drive tooth plate 13.

[0028] Please see Figure 1 and Figure 2 Both sides of the upper outer end of the threaded tube 4 are provided with a handle 5, and the handle 5 is connected to the threaded tube 4. The handle 5 is used to rotate the threaded tube 4.

[0029] Please see Figure 2 The threaded pipe 4 has a pressure plate 8 inside, and the pressure plate 8 has four ventilation holes 9 distributed in a ring. The ventilation holes 9 are used for ventilation.

[0030] Please see Figure 1 and Figure 2 A pressure rod 6 is provided at the upper end of the pressure plate 8, and the pressure rod 6 is connected to the pressure plate 8.

[0031] Please see Figure 1 and Figure 2 The upper end of the pressure rod 6 is provided with a top plate 7, and the top plate 7 is connected to the pressure rod 6. The pressure rod 6 is used to control the lifting and lowering of the pressure plate 8.

[0032] Please see Figure 1 and Figure 2 The base frame 1 has two fixed cones 2 inside, which penetrate and extend to the lower end of the base frame 1. The fixed cones 2 are used to insert into the soil.

[0033] This method involves placing the base frame 1 on top of the soil to be sampled, using the foot to step on the fixing cone 2 to insert it into the ground for fixation, then holding the handle 5 and rotating the threaded tube 4. The threaded tube 4, the bottom ring 3, and the soil are engaged by the threads, converting the rotational motion of the threaded tube 4 into linear motion, thus allowing the threaded tube 4 to penetrate deeper into the soil. Pulling the pull ring 10 causes the wire rope 11 to drive the drive tooth plate 13 upward. The drive tooth plate 13 and the transmission gear 14 mesh together, thus converting the linear motion of the drive tooth plate 13 into the rotational motion of the clamping plate 15. The clamping plate 15 clamps the soil towards the center of the threaded tube 4, thereby lifting it up. Then, the threaded tube 4 is pulled out, causing the soil to be pulled up. Pushing the top plate 7 causes the pressure rod 6 to drive the pressure plate 8 to push out the soil inside the threaded tube 4, completing the sampling work.
