There are scales on the outside of the sampling tube, which can enable users to master the insertion depth and achieve the purpose of accurately obtaining soil samples at the required depth. However, the previous soil samplers have some defects in use. They do not have the advantages of combining drilling and sampling, increasing the sampling difficulty, thus reducing the working efficiency of users and not meeting the needs of today's market. Due to the above existing problems, the practicability and usability of the soil sampler are reduced, and a soil sampler is specifically introduced. Summary of the Utility Model

For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0027] The following further describes the present utility model in detail in combination with the full text.

[0028] Combined with the attached Figures 1 - 4 , a portable soil investigation sampler, which includes a hollow tubular drill pipe 1 with openings at both ends. The lower end of the drill pipe 1 is communicated with a sampling head 2. Specifically, the sampling head 2 is a structure with an opening at one end, and the opening end is a blade. The lower end of the drill pipe 1 is communicated with the inside of the sampling head 2. The sampling head 2 can be turned downward to take soil in the land into the inside of the sampling head 2. A first soil sampler 3 is clamped inside the lower end of the drill pipe 1. The first soil sampler 3 and the drill pipe 1 are clamped through protrusions and grooves, and can be disassembled when the first soil sampler 3 is subjected to an external force.

[0029] When the present utility model is specifically implemented, as Figure 2 and Figure 3 shown, a rotary sampling device 5 is installed inside the drill pipe 1. The rotary sampling device 5 includes a sampling drill bit 501 and a second soil sampler 502 connected to the sampling drill bit 501. The drill pipe 1 and the second soil sampler 502 are threadedly connected. Specifically, the lower end of the second soil sampler 502 is an opening structure, and the sampling drill bit 501 can be installed inside the second soil sampler 502 through threads. When the sampling drill bit 501 rotates driven by the handle component 6, the first soil sampler 3 can be pushed to move out of the drill pipe 1.

[0030] In the specific implementation of the present utility model, as Figure 3 shown, a handle component 6 for driving the second soil sampler 502 to move is installed on the second soil sampler 502. The handle component 6 includes a connecting block 601 fixedly arranged inside the drill pipe 1. A connecting rod 602 is threadedly installed inside the connecting block 601. The lower end of the connecting rod 602 is fixedly connected to the second soil sampler 502. The upper end of the connecting rod 602 extends to the outside of the drill pipe 1. A rotating disc 603 is installed at the upper end of the connecting rod 602. The rotating disc 603 can be manually rotated to drive the connecting rod 602 to rotate and move downward inside the connecting block 601, driving the rotary sampling device 5 to move downward.

[0031] With the sampling head 2 facing downward, the soil in the land enters the inside of the sampling head 2 to achieve the first layer of sampling. Then, the handle component 6 drives the rotary sampling device 5 to push the first soil sampler 3 to move out of the drill pipe 1, and the sample in the first soil sampler 3 is taken out. Then, when aligning with the soil in the land, the handle component 6 is rotated again to drive the rotary sampling device 5 to rotate downward for sampling. It achieves the functions of telescopic lifting and layered soil sampling through this mechanism, meets the soil sampling requirements of different needs, solves the problems of portability, miniaturization, layered soil sampling and inspection of daily tools for outdoor and field research. The soil pushing and cleaning device 4 is set to facilitate the sampler to clean this mechanism, thereby greatly improving the sampling efficiency of the sampler for the soil quality of the land, and also ensuring the inspection quality of the soil samples in different depth soil layers subsequently.

[0032] In the specific implementation of the present utility model, as Figure 3 and Figure 4 shown, a soil pushing and cleaning device 4 is installed on the sampling head 2. The soil pushing and cleaning device 4 includes a movable ring 401 arranged outside the drill pipe 1 and a soil pushing plate 402 that can slide inside the sampling head 2. Guide rods 403 are oppositely installed on the soil pushing plate 402 and the guide rods 403 penetrate through the sampling head 2. A spring 404 is installed outside the guide rods 403 and between the movable ring 401 and the sampling head 2. A through hole 7 for cooperating with the guide rods 403 is opened on the sampling head 2. After sampling, the movable ring 401 can be pushed to move, compressing the spring 404, and the guide rods 403 move in the through hole 7, causing the soil pushing plate 402 to slide inside the sampling head 2 to push out the remaining soil and clean the inside of the sampling head 2.

[0033] A discharge port 9 for cooperating with the first soil sampler 3 is opened on the soil pushing plate 402.

[0034] Foot pedals 8 are oppositely installed on the sampling head 2. Specifically, when in use, both feet can step on the foot pedals 8, and by applying their own gravity, the sampling head 2 is made to sample downward.

[0035] The working principle of the present utility model:

[0036] Turn the sampling head 2 downward, step on the foot pedal 8 with both feet, and apply force through its own gravity to make the sampling head 2 take samples downward. The soil in the land enters the inside of the sampling head 2 and then enters the first soil sampler 3. The handle component 6 drives the rotary sampling device 5 to push the first soil sampler 3 to move out of the drill pipe 1, take out the sample in the first soil sampler 3, take out the first soil sampler 3, and then align the sampling head 2 with the soil in the land. Rotate the handle component 6 again to drive the rotary sampling device 5 to rotate downward for sampling. The sampling drill bit 501 rotates to break the soil, and the soil enters the second soil sampler 502 to complete the sampling.

[0037] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown throughout the text is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. In short, if those of ordinary skill in the art are inspired by it and, without departing from the purpose of the creation of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
