Description

Technical Field

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

[0002] Soil sampling involves collecting and analyzing soil samples from the field. When sampling and analyzing soil profiles, soil layers need to be divided based on factors such as color, structure, texture, compaction, temperature, and distribution of plant roots, and then carefully observed and analyzed.

[0003] A soil sampler is a tool used to obtain soil samples. Commonly used ones include soil drills, shovels, and spades. A soil drill consists of a drill bit and a handle made of hard material. The drill bit is often spiral or cylindrical. The top of the spiral drill bit has a pair of sharp cutting edges that can rotate and cut into the soil. Next to the cutting edges is a large cavity for holding soil. As the handle is rotated, the drill goes down into the soil surface, allowing soil samples from the desired soil layer to be introduced into the cavity.

[0004] Currently, conventional soil samplers are unable to perform stratified sampling of soil at different depths, resulting in a single type of soil sample. In use, the sampler is a single unit, and when the collected soil needs to be transported, it also needs to be transferred, which can easily cause soil contamination and make it difficult to use. Therefore, we have proposed a soil profile stratified sampler to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a soil profile stratification sampler, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A soil profile stratified sampler includes a mounting plate. An outer cylinder is fixedly mounted on the lower surface of the mounting plate, and both the upper and lower sides of the outer cylinder are open. An inner cylinder is mounted on the lower surface of the outer cylinder through a locking mechanism. A partition mechanism is provided between the inner walls of the inner cylinder. Four drive mechanisms are fixedly mounted on the mounting plate corresponding to the inner cylinder, and the drive mechanisms are movably inserted into the inner cylinder.

[0007] Furthermore, the lower surface of the outer cylinder is a sloping structure, and a limit ring is fixedly installed on the inner wall of the outer cylinder at a position corresponding to the upper surface of the inner cylinder.

[0008] Furthermore, the locking mechanism includes a threaded hole and a locking bolt. Threaded holes are provided on the side walls of both the outer cylinder and the inner cylinder. The locking bolt is installed in the threaded hole, and the outer surface of the locking bolt is perpendicular and flush with the outer surface of the outer cylinder.

[0009] Furthermore, the upper and lower sides of the inner cylinder are both open structures, and the lower surface of the inner cylinder has a tapered cross-section.

[0010] Furthermore, the dividing mechanism includes a cross plate and sampling chambers. The cross plate is fixedly installed between the inner walls of the inner cylinder, and the cross plate divides the inner cylinder into four sampling chambers.

[0011] Furthermore, observation ports are provided on the inner cylinder sidewalls corresponding to the sampling chamber.

[0012] Furthermore, the drive mechanism includes a ball screw, a bearing assembly, a handle, a ball nut, a connecting pipe, and a plug. The ball screw is fixedly mounted on the mounting plate via the bearing assembly. A handle is fixedly mounted on the upper surface of the ball screw. A ball nut is provided on the ball screw. A connecting pipe is fixedly mounted on the lower surface of the ball nut. A plug is fixedly mounted on the lower surface of the connecting pipe, and the plug is movably inserted into the sampling chamber.

[0013] Furthermore, the top view cross-section of the plug matches the top view cross-section of the sampling chamber.

[0014] Compared with the prior art, the present invention provides a soil profile stratification sampler, which has the following beneficial effects: This invention utilizes four driving mechanisms that move upwards at different depths within the inner cylinder's partition mechanism, allowing soil samples of varying depths to enter the collection chamber. This enables the inner cylinder to collect soil samples at different depths and in layers, resulting in more diverse soil sampling and more accurate subsequent testing results. Furthermore, the locking mechanism allows for the disassembly and assembly of the outer and inner cylinders, and the driving mechanisms can detach from the inner cylinder, allowing for the transfer of soil along with the inner cylinder. This effectively prevents soil contamination and ensures the accuracy of subsequent testing results. Attached Figure Description

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.

[0018] like Figures 1-4 As shown, a soil profile stratified sampler proposed in one embodiment of the present invention includes a mounting plate 1. An outer cylinder 2 is fixedly mounted on the lower surface of the mounting plate 1, and the upper and lower sides of the outer cylinder 2 are both open structures. An inner cylinder 4 is mounted on the lower surface of the outer cylinder 2 through a locking mechanism 3. A partition mechanism 5 is provided between the inner walls of the inner cylinder 4. Four driving mechanisms 6 are fixedly mounted on the mounting plate 1 corresponding to the inner cylinder 4, and the driving mechanisms 6 are movably inserted into the inner cylinder 4.

[0019] like Figure 2 As shown, in some embodiments, the lower surface of the outer cylinder 2 is a sloped structure, and a limit ring 7 is fixedly installed on the inner wall of the outer cylinder 2 at a position corresponding to the upper surface of the inner cylinder 4.

[0020] In this embodiment, the inclined surface of the lower surface of the outer cylinder 2 facilitates insertion into the soil, and the limiting ring 7 limits the inner cylinder 4 to ensure stable installation of the inner cylinder 4.

[0021] like Figure 2 As shown, in some embodiments, the locking mechanism 3 includes a threaded hole 301 and a locking bolt 302. Threaded holes 301 are provided on the side walls of both the outer cylinder 2 and the inner cylinder 4. The locking bolt 302 is installed in the threaded hole 301, and the outer surface of the locking bolt 302 is perpendicular and flush with the outer surface of the outer cylinder 2.

[0022] In this embodiment, the locking bolt 302 is threaded into the threaded hole 301 on the side wall of the outer cylinder 2 and the inner cylinder 4, so that the outer cylinder 2 and the inner cylinder 4 are locked and fixed.

[0023] like Figure 2 As shown, in some embodiments, the upper and lower sides of the inner cylinder 4 are open structures, and the lower surface of the inner cylinder 4 has a tapered cross-section.

[0024] In this embodiment, the opening on the upper surface of the inner cylinder 4 facilitates the insertion of the drive mechanism 6, and the tapered structure on the lower surface of the inner cylinder 4 facilitates the insertion of the inner cylinder 4 into the soil.

[0025] like Figure 3As shown, in some embodiments, the dividing mechanism 5 includes a cross plate 501 and a sampling chamber 502. The cross plate 501 is fixedly installed between the inner walls of the inner cylinder 4, and the cross plate 501 divides the inner cylinder 4 into four sampling chambers 502.

[0026] In this embodiment, the four sampling chambers 502 formed by the cross plate 501 in the inner cylinder 4 are capable of collecting soil samples at different depths.

[0027] like Figure 3 As shown, in some embodiments, observation ports 8 are provided on the inner cylinder 4 corresponding to the sampling chamber 502.

[0028] In this embodiment, the observation port 8 facilitates the viewing of the soil in the inner cylinder 4.

[0029] like Figure 4 As shown, in some embodiments, the drive mechanism 6 includes a ball screw 601, a bearing assembly 602, a handle 603, a ball nut 604, a connecting pipe 605, and a plug 606. The ball screw 601 is fixedly mounted on the mounting plate 1 via the bearing assembly 602. The handle 603 is fixedly mounted on the upper surface of the ball screw 601. The ball nut 604 is provided on the ball screw 601. The connecting pipe 605 is fixedly mounted on the lower surface of the ball nut 604. The plug 606 is fixedly mounted on the lower surface of the connecting pipe 605, and the plug 606 is movably inserted into the sampling chamber 502.

[0030] In this embodiment, the handle 603 drives the ball screw 601 to rotate in the bearing assembly 602, which in turn drives the ball nut 604 to rotate. The ball nut 604 drives the plug 606 to move up and down in the sampling chamber 502 through the connecting pipe 605.

[0031] like Figure 3 As shown, in some embodiments, the top view cross-section of the plug 606 matches the top view cross-section of the sampling chamber 502.

[0032] In this embodiment, the outer surface of the plug 606 can move stably up and down along the inner wall of the sampling chamber 502.

[0033] In use, the plug 606 in the drive mechanism 6 is inserted into the sampling chamber 502 in the inner cylinder 4. The inner cylinder 4 is then moved upwards, and the locking bolt 302 in the locking mechanism 3 is threaded into the threaded holes 301 on the side walls of the outer cylinder 2 and the inner cylinder 4, thus locking and fixing the outer cylinder 2 and the inner cylinder 4. The outer cylinder 2 and the inner cylinder 4 are then inserted into the soil. When the inner cylinder 4 reaches the required sampling depth, the handle 603 in one of the drive mechanisms 6 drives the ball screw 601 to rotate in the bearing assembly 602. The ball screw 601 drives the ball nut 604 to rotate, and the ball nut 604 drives the plug 606 to move upwards in the sampling chamber 502 through the connecting pipe 605. At this time, the inner cylinder 4 continues to move downwards. This allows soil to enter the sampling chamber 502 that leaks upward from the plug 606. Similarly, the outer cylinder 2 and inner cylinder 4 move downward to the required depth, causing another drive mechanism 6 to move upward, allowing the corresponding sampling chamber 502 to leak out for soil collection. After soil collection is completed, the outer cylinder 2 and inner cylinder 4 are removed, and the locking mechanism 3 is disassembled, allowing the inner cylinder 4 to be removed from the outer cylinder 2. The soil inside the sampling chamber 502 can be viewed through the observation port 8, thus enabling the soil to be transported along with the inner cylinder 4. This allows for layered collection of soil at different depths, making soil sampling more diverse, subsequent test results more accurate, effectively avoiding soil contamination, and ensuring the accuracy of subsequent test results.

[0034] In summary, this soil profile stratification sampler, through the cooperation of the dividing mechanism 5 and the driving mechanism 6 of the inner cylinder 4, enables the inner cylinder 4 to meet the requirements of stratified sampling of soil at different depths, making soil sampling more diverse, subsequent test results more accurate, and facilitating the disassembly and assembly of the inner cylinder 4. It also allows for the transfer of soil along with the inner cylinder 4, effectively avoiding soil contamination and ensuring the accuracy of subsequent test results.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
