[0002] Environmental soil testing and sampling is a process of collecting representative soil samples from a specific environmental area using scientific methods and standardized procedures to provide a basis for subsequent analysis of the soil's physical, chemical, and biological properties.

[0003] Currently, manual soil samplers are inexpensive, but their design is not simple and convenient, their fixed structure is difficult to disassemble, and they are not easy to carry around for work. An existing patent (publication number: CN220670984U) discloses a portable soil sampling device. This utility model provides a portable soil sampling device with a handle, a movable rod, a connecting rod, and a pair of side grooves on the main rod. This allows for easy manipulation of the movable rod via the handle to pull the soil sampling drill bit into a nested configuration with the main rod. The movable rod and connecting rod can then be disassembled, facilitating the storage of the portable soil sampling device and making it easy to carry. Furthermore, a soil-opening frame facilitates fixing the soil sampling drill bit to the ground, improving its stability during sampling. A foot pedal allows for convenient foot pressure on the main rod to press down on the soil sampling drill bit.

[0004] Existing patents offer solutions to the above problems, but some existing environmental soil sampling tubes are quite long. After sampling, when the soil is pushed out of the sampling tube, soil at different depths will stick together, affecting the accuracy of subsequent testing.

[0005] Therefore, an environmental soil testing and sampling device is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an environmental soil testing and sampling device that can solve the problem that in some existing environmental soil sampling methods, the sampling tube is too long, and when the soil is pushed out of the sampling tube after sampling, soil at different depths will stick together, affecting the accuracy of subsequent testing.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an environmental soil testing and sampling device, comprising a sampling tube body, an opening mechanism provided on the front side of the sampling tube, a connecting mechanism provided on the top of the sampling tube body, a sealing cap provided on the bottom of the sampling tube, and a handle fixedly connected to the top of the sampling tube body. The opening mechanism includes several teeth, an opening cover, several connecting holes, and several screws. The teeth are evenly fixed to the bottom of the sampling cylinder body and the opening cover. The connecting holes are opened inside the opening cover. The rear side of the screws passes through the connecting holes and is connected to the internal threads of the sampling cylinder body.

[0008] Preferably, the connecting mechanism includes a connecting sleeve, two first through holes, a limiting pin, and a magnet. The bottom of the connecting sleeve is fixedly connected to the top of the sampling cylinder, the two first through holes are respectively opened on both sides of the connecting sleeve, and the right side of the magnet is fixedly connected to the left side of the limiting pin.

[0009] Preferably, a connecting rod is fixedly connected to the bottom of the handle, and the connecting rod is movably inserted into the inside of the connecting sleeve.

[0010] Preferably, the connecting rod has a second through hole inside, the right side of the limiting pin passes through the first through hole and the second through hole on the left side in sequence and extends to the outside of the first through hole on the right side, and the right side of the magnet is magnetically attracted to the left side of the connecting sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This application sets up an opening mechanism, which allows the sampling tube body and the bottom of the opening cover to easily cut into the soil. The opening cover is fixed to the front of the sampling tube body by means of connecting holes and screws to prevent soil leakage during sampling. After sampling, the screws are removed and the opening cover is separated by pull rings.

[0018] 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.

[0019] Please see Figure 1-7 The present invention provides the following technical solution: An environmental soil testing and sampling device includes a sampling tube body 1, an opening mechanism 2 is provided on the front side of the sampling tube, a connecting mechanism 3 is provided on the top of the sampling tube body 1, a sealing cap 7 is provided on the bottom of the sampling tube, and a handle 5 is fixedly connected to the top of the sampling tube body 1. The opening mechanism 2 includes several teeth 201, an opening cover 202, several connecting holes 203 and several screws 204. The teeth 201 are evenly fixed to the bottom of the sampling cylinder body 1 and the opening cover 202. The connecting holes 203 are opened inside the opening cover 202. The rear side of the screws 204 passes through the connecting holes 203 and is threadedly connected to the inside of the sampling cylinder body 1.

[0020] In this embodiment: the sampling cylinder body 1 is used to hold soil samples. The teeth 201 of its front opening mechanism 2 can easily cut into the soil. The opening cover 202 is fixed to the sampling cylinder body 1 through the connecting hole 203 and the screw 204 to prevent soil leakage during sampling. In the connecting mechanism 3 at the top of the sampling cylinder body 1, the first through hole 302, the limiting pin 303, and the magnet 304 on both sides of the connecting sleeve 301 cooperate to fix the connecting rod 4 at the bottom of the handle 5, making it convenient to hold the handle 5. While pressing the sampling cylinder body 1 and the opening cover 202 downward, the cylinder body 1 is rotated into the soil for sampling. After sampling, the sealing cover 7 seals the soil through the threaded connection. The anti-slip post 10 facilitates rotation operation and limits... Pulling out the pin 303 allows for the removal of the handle 5, facilitating the storage of the sampling tube and the soil sample inside, thus improving the convenience of soil storage after sampling. The scale groove 6 on the sampling tube body 1 makes it easy to determine the sampling depth. It, along with the opening cover 202, teeth 201, and sealing cover 7, are made of tungsten carbide reinforced steel, which is wear-resistant and corrosion-resistant. After returning to the laboratory, the sealing cover 7 and screw 204 are removed, and the pull ring 8 is pulled to separate the opening cover 202. Soil samples from different locations can be taken out for testing as needed. This solves the problem that in some existing environmental soil sampling methods, the sampling tube is too long, and when the soil is pushed out of the sampling tube after sampling, soil at different depths will stick together, affecting the accuracy of subsequent testing.

[0021] Specifically, such as Figure 4 As shown, the connecting mechanism 3 includes a connecting sleeve 301, two first through holes 302, a limiting pin 303, and a magnet 304. The bottom of the connecting sleeve 301 is fixedly connected to the top of the sampling cylinder. The two first through holes 302 are respectively opened on both sides of the connecting sleeve 301. The right side of the magnet 304 is fixedly connected to the left side of the limiting pin 303.

[0022] Specifically, such as Figure 4 and Figure 5 As shown, a connecting rod 4 is fixedly connected to the bottom of the handle 5, and the connecting rod 4 is movably inserted into the inside of the connecting sleeve 301.

[0023] Specifically, such as Figure 4 and Figure 5As shown, the connecting rod 4 has a second through hole 9 inside. The right side of the limiting pin 303 passes through the left first through hole 302 and the second through hole 9 in sequence and extends to the outside of the right first through hole 302. The right side of the magnet 304 is magnetically attracted to the left side of the connecting sleeve 301.

[0024] In this embodiment, the connecting mechanism 3, through the connecting sleeve 301, the first through hole 302, the limiting pin 303, the magnet 304, and the connecting rod 4 and the second through hole 9, achieves a stable connection and quick separation between the handle 5 and the sampling tube body 1. This ensures the reliability of hand operation during sampling and facilitates the disassembly of the handle 5 after sampling to store the sampling tube and the soil sample inside, thus improving ease of use.

[0025] Specifically, such as Figure 1 , Figure 3 and Figure 6 As shown, the surface of the sampling cylinder body 1 and the surface of the opening cover 202 are both threadedly connected to the inner wall of the sealing cover 7. Anti-slip posts 10 are fixedly connected to the surface of the sealing cover 7. There are several anti-slip posts 10, which are evenly distributed on the surface of the sealing cover 7.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, the surface of the sampling cylinder body 1 is provided with a scale groove 6, and the number of scale grooves 6 is several and they are evenly distributed on the surface of the sampling cylinder body 1.

[0027] In this embodiment: the sealing cap 7 is threadedly connected to the sampling cylinder body 1 and the opening cap 202, and works with the anti-slip post 10 to achieve convenient sealing operation. After soil sampling is performed in the cylindrical space formed by the sampling cylinder body 1 and the opening cap 202, the cylindrical space can be quickly sealed to effectively prevent soil moisture evaporation. The scale groove 6 can intuitively display the sampling depth, which is conducive to obtaining accurate soil information at different depths.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, the sampling cylinder body 1, the opening cover 202, the teeth 201 and the sealing cover 7 are all made of tungsten carbide reinforced steel.

[0029] Specifically, such as Figure 2 As shown, a pull ring 8 is fixedly connected to the top of the opening cover 202.

[0030] In this embodiment: the sampling cylinder body 1, the opening cover 202, the teeth 201 and the sealing cover 7 are made of tungsten carbide reinforced steel, which gives it excellent wear resistance and corrosion resistance and makes it suitable for polluted soil environments. The pull ring 8 is designed to facilitate the separation of the opening cover 202 from the sampling cylinder body 1.

[0031] Working principle: The sampling cylinder body 1, as the core component, is used to contain soil samples. Its front opening mechanism 2, through several teeth 201 evenly fixed to the bottom of the sampling cylinder body 1 and the opening cover 202, can more easily cut into the soil, ensuring smooth sampling. The opening cover 202 is fixed to the sampling cylinder body 1 through internal connecting holes 203 and several screws 204 threaded through the connecting holes 203 and connected to the inside of the sampling cylinder body 1, ensuring that soil will not leak from the connection point during sampling. In the connecting mechanism 3 at the top of the sampling cylinder body 1, the bottom of the connecting sleeve 301 is fixed to the top of the sampling cylinder. Two first through holes 302 on both sides, in conjunction with a limiting pin 303 and a magnet 304 fixedly connected to the left side of the limiting pin 303, can achieve connection... The rod 4 is fixed in place, and the connecting rod 4 fixed at the bottom of the handle 5 is movably inserted into the connecting sleeve 301. The second through hole 9 inside the connecting rod 4 allows the limiting pin 303 to pass through. The right side of the limiting pin 303 passes through the left first through hole 302 and the second through hole 9 in sequence and extends to the outside of the right first through hole 302. At the same time, the right side of the magnet 304 is magnetically attracted to the left side of the connecting sleeve 301, ensuring the stability of the connection between the handle 5 and the sampling cylinder body 1. This makes it convenient to hold the handle 5 and press down the sampling cylinder body 1 and the opening cover 202 while rotating it into the soil to perform sampling. After sampling, the surfaces of the sampling cylinder body 1 and the opening cover 202 are threadedly connected to the inner wall of the sealing cover 7. Several evenly distributed anti-slip posts 10 on the surface of the sealing cover 7 facilitate the rotation of the sealing cover 7. The grooved connection ensures a tight seal for the soil inside the sampling cylinder body 1, preventing moisture evaporation. Pulling out the limiting pin 303 releases the limiting on the connecting rod 4, separating it from the connecting sleeve 301, thus allowing the handle 5 to be removed for easy storage of the sampling cylinder and its internal soil sample. Several evenly distributed graduated grooves 6 on the surface of the sampling cylinder body 1 visually display the sampling depth, facilitating the acquisition of soil information at different depths. Since the sampling cylinder body 1, opening cover 202, teeth 201, and sealing cover 7 are all made of tungsten carbide reinforced steel, they possess excellent wear resistance and corrosion resistance, adapting to polluted soil environments. After returning to the laboratory, the sealing cover 7 is removed, followed by the screw 204. Pulling the pull ring 8 fixed to the top of the opening cover 202 allows the opening cover 202 to be opened. Separated from the sampling cylinder body 1, soil at the required depth is removed for testing. This avoids the problem of soil at different depths adhering to the inner wall of the sampling cylinder body 1 when the soil is directly pushed out of the body, ensuring the accuracy of subsequent soil testing and improving the convenience of storing the sampled soil. It also solves the problem of existing environmental soil sampling cylinders being too long, causing soil at different depths to adhere to each other when the soil is pushed out of the cylinder after sampling, affecting the accuracy of subsequent testing. It should be noted that when the cylindrical space formed by the sampling cylinder body 1 and the opening cover 202 rotates into the soil, the air inside will be expelled from the soil and the inner wall of the sampling cylinder body 1 and the inner wall of the opening cover 202.It will not affect normal soil sampling.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
