During the environmental investigation process, sampling the soil in the area to be investigated is a conventional inspection method. There are various ways of soil sampling. The most common ones are the short-stem soil drill for collecting shallow soil samples and the sleeve soil drill for observing the profile characteristics in the underground soil layer;

[0003] After retrieval, in the prior art, there is a "soil collection device for environmental monitoring" with the publication number of "CN219038456U". This device pushes the soil to be sampled into the sampling cylinder to facilitate the removal of the sampled soil. However, during the sampling process, holes need to be opened inside the soil, which will increase the contact with the soil during the gradual penetration process, resulting in an increase in friction, increasing the difficulty of soil sampling operations, and affecting the work efficiency of soil sampling.

[0004] Therefore, a soil sampling device for environmental monitoring is proposed to solve the above problems. Content of the Utility Model

A vertical rod is fixedly connected to the surface of the storage tube. The vertical groove is slidably connected to the surface of the vertical rod. The vertical groove and the vertical rod drive rotation during sampling.

[0010] Preferably, a pulling rod is fixedly connected to the upper end of the inner wall of the storage tube. Side holes are formed on both sides of the storage tube. The pulling rod and the side holes cooperate to take out the sample after sampling.

[0011] Preferably, a plurality of export ridges are annularly distributed along the surface of the outer tube. The export ridges are spiral-shaped. The export ridges are arranged to reduce contact with the inner wall of the soil hole and improve the smoothness of sampling.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Specific implementation: As Figures 1-5 shown, a soil sampling device for environmental monitoring includes: an upper frame 1, with handles 2 fixedly connected to both sides of the upper frame 1; a sampling mechanism 3, and the sampling mechanism 3 is installed on the inner wall of the upper frame 1; among them, the sampling mechanism 3 includes a material storage component 31 installed at the lower end of the upper frame 1, the surface of the material storage component 31 extends into the interior of the upper frame 1, an excavation component 32 is installed on the surface of the material storage component 31, and the lower end of the excavation component 32 extends below the material storage component 31;

[0024] As Figure 1 , Figure 4 and Figure 5 shown, the material storage component 31 includes an outer tube 311 fixedly connected to the inner wall of the upper frame 1, an inner ring groove 314 is opened inside the outer tube 311, a material storage tube 312 is slidably connected to the inner wall of the inner ring groove 314, a plurality of export ribs 313 are fixedly connected to the surface of the outer tube 311, a side groove 319 is opened at the upper end of the outer tube 311, a vertical groove 315 is opened inside the outer tube 311, the vertical groove 315 communicates with the inner ring groove 314, a vertical rod 316 is fixedly connected to the surface of the material storage tube 312, the vertical groove 315 is slidably connected to the surface of the vertical rod 316, a pull-out rod 317 is fixedly connected to the upper end inner wall of the material storage tube 312, side holes 318 are opened on both sides of the material storage tube 312, and a plurality of export ribs 313 are annularly distributed along the surface of the outer tube 311, and the export ribs 313 are spiral;

[0025] When the device is in use, the material storage pipe 312 can be inserted into the inner ring groove 314. Due to the cooperation between the vertical groove 315 and the vertical rod 316, a longitudinal sliding effect can be formed. After the internal sampling is completed, the pulling rod 317 can be manually pulled to drive the material storage pipe 312 to move accordingly. If the sample inside the material storage pipe 312 cannot be taken out, the two wedges at the side groove 319 can be squeezed into the side hole 318 by tools, so that the side hole 318 is pushed upward to assist the sampling operation of the pulling rod 317.

[0026] As Figure 1 , Figure 2 and Figure 3 As shown in , , , , and , the excavation assembly 32 includes a fixing ring 321 fixedly connected to the lower end of the outer pipe 311 surface.

[0027] When the device is in use, the soil can be excavated by the excavation inclined block 323. During the use process, the lower end of the outer pipe 311 drives the fixing inclined plate 322 and the outer pipe 311 to rotate accordingly. At this time, excessive excavation is formed on the inner wall of the soil collection hole. In cooperation with the spiral arrangement of the guiding ridges 313, the soil is gradually driven upward, reducing the frictional contact between the inner wall of the hole and the material storage pipe 312 during the collection process and maintaining the smoothness of sampling.

[0028] When the utility model is in use, when the device is in use, by inserting the material storage pipe 312 into the inner ring groove 314, due to the cooperation between the vertical groove 315 and the vertical rod 316, a longitudinal sliding effect is formed. After the internal sampling is completed, the pulling rod 317 is manually pulled to drive the material storage pipe 312 to move accordingly. If the sample inside the material storage pipe 312 cannot be taken out, the two wedges at the side groove 319 are squeezed into the side hole 318 by tools to make the side hole 318 push upward. When the device is in use, the soil is excavated by the excavation inclined block 323. During the use process, the lower end of the outer pipe 311 drives the fixing inclined plate 322 and the outer pipe 311 to rotate accordingly. Excessive excavation is formed on the inner wall of the soil collection hole. In cooperation with the spiral arrangement of the guiding ridges 313, the soil is gradually driven upward, reducing the frictional contact between the inner wall of the hole and the material storage pipe 312 during the collection process and maintaining the smoothness of sampling.
