Description

Technical Field

[0001] This utility model relates to the field of soil and water conservation monitoring technology, specifically to a sampling device for soil and water conservation testing. Background Technology

[0002] Soil and water conservation monitoring helps to understand the types, intensity and distribution characteristics, hazards and impacts of soil erosion, its occurrence and development patterns, and dynamic trends. This is of great significance for macro-level decision-making on comprehensive soil and water conservation and ecological environment construction, as well as for the scientific, rational, and systematic deployment of various soil and water conservation measures. Soil sampling is a common testing method that facilitates subsequent analysis of soil composition.

[0003] A sampler for soil and water conservation monitoring, with existing patent number CN117538095B, ​​facilitates sampling and testing of deep soil through the sealed combination of an openable and closable cone. During drilling, the closed cone reduces resistance, making the drilling process easier and less strenuous. A sampling tube is installed inside the drill barrel, allowing soil samples to be directly deposited. After sampling, the tube is pushed out of the drill barrel via a push-pull assembly, enabling sample storage and transport without container replacement. This makes the sampling process more convenient and faster, avoiding the risk of sample spillage or contamination during discharge and container replacement, ensuring soil testing accuracy. Furthermore, the push-pull assembly and sampling tube work together to open the openable and closable cone during sampling, making the opening process even more convenient.

[0004] Existing technologies often lack a proper tunneling structure. When moving into the soil, they rely solely on a conical tip at the bottom, which is inconvenient. Furthermore, the drill pipe is directly in contact with the soil, making it unclear how to remove the bottom soil during tunneling. Without a clearing structure, the device experiences strong compressive forces as it moves to the bottom, hindering tunneling. Additionally, the sampling tube lacks the ability to break up the soil, making it difficult to move soil into the sampling tube. Moreover, after sampling, the entire device must be pulled back to the top, preventing repeated sampling. Summary of the Invention

[0005] The purpose of this invention is to provide a sampling device for soil and water conservation testing, which solves the problems of existing sampling devices being inconvenient to move into the soil and to repeat sampling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for soil and water conservation testing, comprising a tunneling cylinder, a rotating rod being installed through the center of the tunneling cylinder, a receiving cylinder being installed on the outer wall of the bottom end of the rotating rod, and multiple conical plates being rotatably connected to the bottom end of the tunneling cylinder; magnets are installed between the multiple conical plates to attract and adhere to each other.

[0007] A spiral impeller is fixedly connected around the bottom outer wall of the tunneling cylinder, and rotating rods are fixedly connected symmetrically on both sides of the top of the tunneling cylinder.

[0008] A helical blade is fixedly connected to the outer wall of the bottom end of the rotating rod, and the edge of the helical blade is in contact with the inner wall of the receiving cylinder.

[0009] The outer wall of the receiving cylinder is rotatably connected to the inner bottom of the tunneling cylinder by threads, and a sealing cover is connected to the top of the receiving cylinder.

[0010] Preferably, the inner wall of the bottom end of the tunneling cylinder is provided with a circumferential thread protruding towards the center, and the outer wall of the receiving cylinder is provided with a threaded groove that is recessed inward and corresponds to the circumferential thread on the inner wall of the tunneling cylinder.

[0011] Preferably, the bottom of the conical plate is inclined towards the center, and the top of the conical plate is rotatably connected to a rotating shaft. The center of the top of the conical plate is rotatably connected to the bottom edge of the tunneling cylinder via the rotating shaft, and a torsion spring is installed inside the rotating shaft. The bottoms of multiple conical plates are all inclined towards the center of the tunneling cylinder and fit together. The two ends of the torsion spring are fixedly connected to the rotating shaft and the tunneling cylinder, respectively. The torsion spring can accumulate energy when the conical plate drives the rotating shaft to rotate. When the push on the conical plate is released, the rotating shaft rotates in the opposite direction, thereby driving the conical plate to rotate in the opposite direction, so that the multiple conical plates fit together again.

[0012] Preferably, the sealing cover is fixedly connected to the outer wall of the rotating rod, and multiple fixing bolts are installed through the inner wall of the sealing cover. The fixing bolts penetrate the interior of the sealing cover and are threadedly connected to the top of the receiving cylinder. The sealing cover is fixedly connected to the receiving cylinder by the fixing bolts.

[0013] Preferably, the end of the rotating rod away from the tunneling cylinder is slidably connected to an extension rod, and the diameter of the outer wall of the spiral impeller at the bottom of the outer wall of the tunneling cylinder is smaller than the diameter of the baffle.

[0014] Preferably, a knob is fixedly installed on the top of the rotating rod, and a through hole corresponding to the rotating rod is opened at the center of the baffle.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By rotating the rotating rod, the tunneling cylinder rotates, causing the conical plate to rotate. Simultaneously, the inclination of the conical plate compresses the soil towards the edge, allowing the soil to move to the outer wall of the tunneling cylinder. The rotation of the tunneling cylinder also drives the spiral impeller to rotate, which can easily move the soil to the top, transporting the soil during tunneling to the outside. This also avoids the tunneling cylinder from squeezing against the inner wall of the soil, reducing friction and facilitating tunneling to the bottom. At the same time, the extension rod inside the rotating rod can be pulled out to adjust the operator's rotation position. This allows the operator to be further away when the tunneling cylinder rotates, resulting in a longer lever arm and thus less effort. This facilitates the movement of the device into the soil, making subsequent sampling operations easier.

[0017] 2. The container is equipped with spiral blades inside. When the rotating rod rotates, it drives the spiral blades to rotate, causing the soil at the bottom to be rotated and carried into the container. Simultaneously, the continuous rotation of the spiral blades also causes the soil to continuously move into the container, thus compressing and compacting the soil for easy collection. When removing the soil, the rotating rod can be rotated in the opposite direction to move the container to the top, thereby pulling the container out of the tunneling cylinder without pulling the tunneling cylinder. At the same time, the fixing bolts can be easily rotated to release the sealing cover from the container, making it easy to remove the spiral blades from the container and clean out the sampled soil. It can be easily reassembled and reinserted into the tunneling cylinder for repeated sampling. Attached Figure Description

[0026] 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.

[0027] This utility model provides, for example Figure 1-5 The sampling device for soil and water conservation testing shown includes a tunneling cylinder 1, a rotating rod 2 installed through the center of the tunneling cylinder 1, a receiving cylinder 3 installed on the bottom outer wall of the rotating rod 2, and multiple conical plates 4 rotatably connected to the bottom end of the tunneling cylinder 1; a spiral impeller 101 is fixedly connected around the bottom outer wall of the tunneling cylinder 1, and rotating rods 102 are symmetrically fixedly connected to both sides of the top of the tunneling cylinder 1; a spiral blade 203 is fixedly connected to the bottom outer wall of the rotating rod 2, and the edge of the spiral blade 203 is in contact with the inner wall of the receiving cylinder 3; the outer wall of the receiving cylinder 3 is rotatably connected to the inner bottom end of the tunneling cylinder 1 by threads, and a sealing cover 301 is connected to the top of the receiving cylinder 3. To ensure a tighter closure of the conical plates 4, magnets can be installed between the multiple conical plates 4, so that the multiple conical plates 4 attract and adhere to each other.

[0028] A spiral thread protrudes from the inner wall of the bottom end of the tunneling cylinder 1 towards the center. A threaded groove corresponding to the spiral thread on the inner wall of the tunneling cylinder 1 is recessed inward on the outer wall of the receiving cylinder 3. The sealing cover 301 is fixedly connected to the outer wall of the rotating rod 2. Multiple fixing bolts 302 are installed through the inner wall of the sealing cover 301. The fixing bolts 302 penetrate the interior of the sealing cover 301 and are threadedly connected to the top of the receiving cylinder 3. The sealing cover 301 is fixedly connected to the receiving cylinder 3 by the fixing bolts 302. The rotating rod 2 drives the receiving cylinder 3 to rotate through the sealing cover 301, so that the receiving cylinder 3 moves to the bottom of the device. Since the receiving cylinder 3 is equipped with a spiral blade 203, the rotation of the rotating rod 2 can drive the spiral blade 203 to rotate, so that the soil at the bottom is rotated and carried into the receiving cylinder 3. At the same time, through the continuous rotation of the spiral blade 203, the soil can also continuously move into the receiving cylinder 3, realizing soil collection.

[0029] The bottom of the conical plate 4 is inclined towards the center, and the top of the conical plate 4 is rotatably connected to the rotating shaft 401. The center of the top of the conical plate 4 is rotatably connected to the bottom edge of the tunneling cylinder 1 through the rotating shaft 401. A torsion spring is installed inside the rotating shaft 401. The two ends of the torsion spring are fixedly connected to the rotating shaft 401 and the outer wall of the tunneling cylinder 1, respectively. The torsion spring can accumulate energy when the conical plate 4 drives the rotating shaft 401 to rotate. When the push on the conical plate 4 is released, the rotating shaft 401 rotates in the opposite direction, thereby driving the conical plate 4 to rotate in the opposite direction, so that the multiple conical plates 4 re-adhere to each other. The bottoms of multiple conical plates 4 are inclined and fitted towards the center of the tunneling cylinder 1. An extension rod is slidably connected to the end of the rotating rod 102 away from the tunneling cylinder 1. The outer diameter of the spiral impeller 101 at the bottom of the outer wall of the tunneling cylinder 1 is smaller than the diameter of the baffle 201. A knob 202 is fixedly installed on the top of the rotating rod 2. A through hole corresponding to the rotating rod 2 is opened at the center of the baffle 201. The soil is squeezed towards the edge by the inclined surface of the conical plates 4, so that the soil can move to the outer wall of the tunneling cylinder 1. The rotation of the tunneling cylinder 1 can also drive the spiral impeller 101 to rotate. The spiral impeller 101 can easily move the soil to the top, transport the soil during excavation to the outside of the top, reduce friction, and facilitate excavation to the bottom. At the same time, the extension rod inside the rotating rod 102 can be pulled out for operation, thus saving more effort.

[0030] In use, the device is moved to the desired sampling location, and then pressed and rotated to the bottom, allowing the conical plate 4 to be inserted into the soil. By rotating the rotating rod 102, the tunneling cylinder 1 is rotated, causing the conical plate 4 to rotate. At the same time, the inclined surface of the conical plate 4 squeezes the soil towards the edge, allowing the soil to move to the outer wall of the tunneling cylinder 1. The rotation of the tunneling cylinder 1 also drives the spiral impeller 101 to rotate, which in turn moves the soil to the top, transporting the soil during tunneling to the outside of the top. This also avoids the tunneling cylinder 1 being squeezed against the inner wall of the soil, reducing friction and facilitating tunneling to the bottom. Additionally, the extension rod inside the rotating rod 102 can be pulled out to adjust the operator's rotation position, increasing the lever arm and making it more labor-saving.

[0031] During sampling, the excavating cylinder 1 moves upward a certain distance, causing the conical plate 4 to move upward as well. This releases the outer wall of the bottom of the conical plate 4 from contact with the soil, allowing the conical plate 4 to rotate and open. When squeezed by the receiving cylinder 3, the conical plate 4 can rotate and tilt around the rotating shaft 401. Turning the knob 202 drives the rotating rod 2 to rotate, which in turn drives the receiving cylinder 3 to rotate via the sealing cover 301. Since the receiving cylinder 3 is connected to the excavating cylinder 1 by threads, it can move downwards during rotation. By squeezing the conical plate 4 at the bottom, the receiving cylinder 3 causes multiple conical plates 4 to rotate and open around the rotating shaft 401, allowing the receiving cylinder 3 to move to the bottom of the device. Because the container 3 has a spiral blade 203 inside, the rotation of the rotating rod 2 drives the spiral blade 203 to rotate, causing the soil at the bottom to be rotated and carried into the container 3. At the same time, the continuous rotation of the spiral blade 203 also causes the soil to continuously move into the container 3, thereby compressing the soil and facilitating soil collection. For soil collection at the corresponding depth, during operation, the spiral impeller 101 drives the soil to the top, transporting the soil from the excavation to the outside of the top, while avoiding mixing with other soil. When picking up, the rotating rod 2 is rotated in the opposite direction, driving the container 3 to the top, pulling the container 3 out from the inside of the excavation tube 1 without pulling the excavation tube 1. At the same time, the fixing bolt 302 can be rotated to release the fixing of the sealing cover 301 to the container 3, remove the spiral blade 203 from the inside of the container 3, clean out the sampled soil, reassemble and reinsert it into the excavation tube 1, and achieve repeated sampling.
