Description
Technical Field
[0001] This utility model relates to the technical field of soil sampling equipment, specifically a lightweight soil testing and sampling device. Background Technology
[0002] In numerous fields such as soil research, environmental monitoring, and agricultural production, accurately obtaining representative soil samples is a crucial prerequisite for in-depth analysis and scientific decision-making. However, many challenges currently exist in the soil sampling process.
[0003] On the one hand, traditional soil samplers often require operators to manually rotate them to insert them into the soil. However, due to different personnel's varying force application habits, it is difficult to apply force evenly. This can easily cause the sampler to tilt during insertion, affecting sampling accuracy. This is especially true when dealing with soils of different textures; harder soils require more force, and operators are more prone to applying uneven force, causing deviations in the sampler's insertion direction.
[0004] On the other hand, even if the initial insertion is smooth during sampling, once the sampler penetrates deep into the soil, it is prone to swaying and shaking due to the soil's reaction force and the unevenness of the surrounding soil. This instability not only makes it difficult to control the sampling depth but may also result in soil samples that do not accurately reflect the true soil conditions of the area. Moreover, the shaking of the sampler may damage the soil structure, affecting subsequent analyses of soil layers and other aspects. Furthermore, the unstable sampling process increases the difficulty and labor intensity for operators, reducing work efficiency. Summary of the Invention
[0005] (a) Technical problems to be solved
[0006] The technical problem this invention aims to solve is that traditional samplers require manual rotation by the operator to insert them into the soil.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0039] Please see Figures 1-8 The portable soil testing and sampling device shown includes a soil sampling drill bit 1 for soil sampling, an extension rod 2 with a tubular structure, a handheld component 3, and a ground insertion component 4. The extension rod 2 is connected to the upper part of the soil sampling drill bit 1, the handheld component 3 is located at the top of the extension rod 2, and the ground insertion component 4 is located at the lower part of the outer ring of the extension rod 2.
[0040] The upper part of the soil sampling drill bit 1 is provided with a threaded hole, and the lower part of the extension rod 2 is connected to the upper part of the soil sampling drill bit 1 by a threaded connection. There are multiple extension rods 2. The lower end of the extension rod 2 closest to the soil sampling drill bit 1 is connected to the soil sampling drill bit 1 by a threaded connection, and adjacent extension rods 2 are connected by a threaded connection. When it is necessary to sample soil samples at different depths, different numbers of extension rods 2 can be spliced to extend the length of the entire sampling device. At the same time, certain scale lines can be set on the outer wall of each extension rod to facilitate the staff to control the sampling depth.
[0041] To improve the stability of the sampling device during sampling and prevent tilting and swaying, the ground insertion assembly 4 is designed to include a first pin 401, a second pin 402, and a collar 403. The collar 403 is movably mounted on the outer wall of the extension rod 2. The collar 403 has an annular groove 404 at both the upper and lower parts. There are two first pins 401 arranged symmetrically, and an annular ring 406 is provided between the two first pins 401. The annular ring 406 is movably mounted in the annular groove 404 at the upper part of the collar 403. There are two second pins 402 arranged symmetrically, and an annular ring 405 is provided between the two second pins 402. The annular ring 405 is movably mounted in the annular groove 404 at the lower part of the collar 403.
[0042] When using it, first rotate pin 1 (401) and pin 2 (402) to the appropriate position and then insert them into the ground. This will fix the extension rod 2 in place and reduce the occurrence of swinging or tilting.
[0043] The handheld assembly 3 includes a horizontal bar 301 and a vertical tube 302. The horizontal bar 301 and the vertical tube 302 are inherently connected, and the lower end of the vertical tube 302 is connected to the extension rod 2 by a threaded connection. The inner cavity of the vertical tube 302 is in communication with the inner cavity of the extension rod 2.
[0044] The bottom end of the soil sampling drill bit 1 is provided with a beveled opening 6, and the side of the soil sampling drill bit 1 is provided with an opening groove 7, the lower end of the opening groove 7 penetrating downward through the soil sampling drill bit 1.
[0045] Specifically, each extension rod 2 has a locking threaded hole 8 on its upper part. When two adjacent extension rods 2 are connected, screws are used to lock and fix the two adjacent extension rods 2 through the locking threaded hole 8.
[0046] In this embodiment, when multiple extension rods 2 are connected, adjacent extension rods 2 can be fixed with screws to increase the rigidity of the connection.
[0047] Specifically, it also includes a bulldozing assembly 5, which includes multiple push rods 501, a gravity block 502, and a bulldozing sleeve 503. The upper end of the bulldozing sleeve 503 is fixedly connected to the gravity block 502, and both are movably set in the inner cavity of the soil-boring drill bit 1. One end of the push rod 501 near the gravity block 502 is fixedly connected to the gravity block 502. Two adjacent push rods 501 are connected by a threaded connection. The push rod 501 near the handheld assembly 3 extends out from the inner cavity of the vertical tube 302. The upper part of the push rod 501 extending out from the inner cavity of the vertical tube 302 is provided with a handle 504 by a threaded connection, and the outer diameter of the handle 504 is larger than the inner diameter of the vertical tube 302.
[0048] In this implementation scheme, the bulldozing component 5 is mainly designed to facilitate the ejection of soil samples from the soil sampling drill bit 1, making it easier for workers to collect soil samples. During use, workers pull the handle 504, which in turn pulls the push rod 501 to move the gravity block 502 and the bulldozing sleeve 503, using impact or compression to eject or squeeze out the soil sample from the soil sampling drill bit 1, thus improving the convenience of soil sample collection.
[0049] Specifically, one end of the crossbar 301 is provided with a storage cavity 303, and one end of the storage cavity 303 is provided with a cap 304 connected to it by a threaded connection. An L-shaped internal hex wrench 305 is fixed on one side of the cap 304, and the internal hex wrench 305 is located in the storage cavity 303.
[0050] In this embodiment, the multiple extension rods 2 can be locked and connected by the internal hex wrench 305 provided in the device itself, even when the operator does not carry a tightening wrench.
[0051] Specifically, the lengths of both pin 1 (401) and pin 2 (402) are greater than the length of the soil sampling drill bit 1. The bulldozer sleeve 503 has a cutting edge 505 on the side near the inclined opening 6, and the thinner end of the cutting edge 505 is located near the inclined opening 6.
[0052] In this embodiment, the cutting edge 505 can effectively cut and separate the soil sample from the inner wall of the soil sampling drill bit 1, making it convenient to remove the soil sample.
[0053] The working principle is as follows: First, the operator selects an appropriate number of extension rods 2 and push rods 501 according to the required sampling depth, assembles the sampling device, and then rotates and separates the first pin 401 and the second pin 402 into a cross-shaped pattern, inserting them into the ground. Then, holding the handheld component 3, the operator presses down on the soil drill bit 1 while rotating it to collect soil samples. During the rotation and pressing process, the force applied by the operator may inevitably cause some tilting, resulting in the extension rod 2 tilting. To prevent this, the first insertion component 4, by penetrating deep into the ground, provides some restraint to the extension rod 2, preventing it from tilting and swaying, thus facilitating the soil sampling process.
[0054] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
