Description

Technical Field

[0001] This utility model relates to the technical field of soil and water testing samplers, specifically a sampler for detecting soil erosion in arable land. Background Technology

[0002] In current agricultural and environmental science research, the detection of soil erosion in arable land is a crucial foundation for assessing soil erosion status and developing soil and water conservation measures. Traditional soil sampling tools are mainly based on a simple sampling tube design, with one end made into a pointed cone shape, which facilitates the penetration of the soil layer by manual rotation or tapping to obtain soil samples. However, these traditional samplers have revealed certain shortcomings in practical applications.

[0003] Traditional sampling tubes often extract the entire soil column when collecting soil samples. While this whole sample is convenient for collection, it presents challenges for subsequent analysis. Especially when specific analyses of different soil depths are required, researchers must manually break up the entire soil sample to separate the layers. This process is not only time-consuming and labor-intensive but also easily damages the original structure and layers of the soil sample, making it difficult to maintain its integrity and thus affecting the accuracy of the analytical results. Utility Model Content

[0004] (I) Purpose of the utility model

[0005] In view of this, the purpose of this utility model is to provide a sampling device for detecting soil erosion in arable land, which solves the problems mentioned in the background above.

[0006] (2) Technical solution

[0007] A sampling device for detecting soil erosion in arable land includes a fixed sampling tube. A fixed plate is fixedly installed at the top of the fixed sampling tube, and a limiting tube is connected to the top of the fixed plate. A long rod is movably installed on the inner wall of the limiting tube, and two sets of operating rods are fixed on the outer surface of the top of the long rod. A movable plate is connected to one end of the long rod, and a third movable sampling tube is connected to one end of the movable plate. A second movable sampling tube is connected to one end of the third movable sampling tube, and a first movable sampling tube is connected to one end of the second movable sampling tube. The third, second, and first movable sampling tubes are all movably installed in the inner wall of the fixed sampling tube.

[0008] Preferably, multiple sets of magnetic grooves are formed on the outer surface of one end of the movable plate, the third movable sampling tube, the second movable sampling tube and the first movable sampling tube, and multiple sets of magnetic pins are fixedly installed on the outer surface of the other end of the third movable sampling tube, the second movable sampling tube and the first movable sampling tube.

[0009] Preferably, the other end of the long rod is connected to an abutment plate.

[0010] Preferably, the outer surfaces of both sets of operating rods are covered with rubber sleeves.

[0011] Preferably, the outer surface of the limiting tube is provided with two sets of limiting holes.

[0012] Preferably, the bottom outer surface of the fixed sampling tube is provided with two sets of mounting grooves, and the inner walls of the two sets of mounting grooves are connected with springs. One end of the spring is connected with a telescopic pin, and the telescopic pin is movably engaged in the inner wall of the limiting hole.

[0013] Preferably, the outer surfaces of the fixed sampling tube and the fixed plate are provided with multiple sets of screw grooves, and the inner walls of the multiple sets of screw grooves are movably installed with bolts.

[0014] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0015] 1. This utility model involves a movable sampling tube that penetrates into the soil along with a fixed sampling tube during the sampling process, filling the soil sample. When sample separation is required, pressing the telescopic pin releases the locking mechanism, pushing the fixed sampling tube to detach the movable sampling tube from its inner wall. Because the movable sampling tubes are interconnected via magnetic grooves and pins, they can be easily separated from the overall structure to form multiple independent soil sample segments. This not only maintains the integrity of the soil sample but also ensures that each sample segment represents the true condition of a specific soil layer, providing a reliable basis for subsequent detailed analysis.

[0016] 2. This utility model uses a rotating operating lever to drive the long rod and movable sampling tube to rotate synchronously, allowing them to penetrate deep into the soil layer for sampling. This design ensures the consistency and stability of the sampling process and enables precise control of the sampling depth. Attached Figure Description

It should be understood that throughout the drawings, identical or similar reference numerals indicate identical or similar parts and features. The drawings merely schematically illustrate the concepts and principles of the embodiments of the present disclosure and do not necessarily depict the specific dimensions and proportions of the various embodiments of the present disclosure. Certain portions of certain drawings may be exaggerated to illustrate relevant details or structures of the embodiments of the present disclosure.

[0027] Please see Figure 1-8 One embodiment provided by this utility model:

[0028] A sampling device for detecting soil erosion in arable land includes a fixed sampling tube 1, a fixed plate 2 fixedly installed at the top of the fixed sampling tube 1, and a limiting tube 3 connected to the top of the fixed plate 2. A long rod 4 is movably installed on the inner wall of the limiting tube 3, and two sets of operating rods 5 are fixed on the outer surface of the top of the long rod 4. A movable plate 411 is connected to one end of the long rod 4, and a third movable sampling tube 911 is connected to one end of the movable plate 411. A second movable sampling tube 9 is connected to one end of the third movable sampling tube 911, and a first movable sampling tube 8 is connected to one end of the second movable sampling tube 9. The third movable sampling tube 911, the second movable sampling tube 9, and the first movable sampling tube 8 are all movably installed in the inner wall of the fixed sampling tube 1.

[0029] Furthermore, multiple sets of magnetic grooves 913 are formed on the outer surface of one end of the movable plate 411, the third movable sampling tube 911, the second movable sampling tube 9, and the first movable sampling tube 8, and multiple sets of magnetic pins 912 are fixedly installed on the outer surface of the other end of the third movable sampling tube 911, the second movable sampling tube 9, and the first movable sampling tube 8. The cooperation of the magnetic grooves 913 and the magnetic pins 912 realizes the tight connection and rapid separation between the movable sampling tubes. This design not only enhances the structural stability during sampling, but also facilitates the subsequent sample separation operation.

[0030] Furthermore, the other end of the long rod 4 is connected to a push plate 7, which allows the operator to easily push out the soil sample from the sampling tube without additional tools or complicated operations.

[0031] Furthermore, the outer surfaces of the two sets of operating levers 5 are covered with rubber sleeves 6, which provide a comfortable grip and anti-slip performance, reducing the difficulty of operation and fatigue.

[0032] Furthermore, two sets of limiting holes 311 are provided on the outer surface of the limiting tube 3, and two sets of mounting grooves 213 are provided on the outer surface of the bottom end of the fixed sampling tube 1. Springs 212 are connected to the inner walls of the two mounting grooves 213, and one end of each spring 212 is connected to a telescopic pin 211. The telescopic pin 211 is movably engaged in the inner wall of the limiting hole 311. The cooperation of the telescopic pin 211 and the spring 212 enables precise control and locking of the long rod 4 during sampling. This design ensures the accuracy of the sampling depth and prevents accidental detachment during sampling.

[0033] Furthermore, multiple sets of screw grooves 111 are provided on the outer surfaces of the fixed sampling tube 1 and the fixed plate 2, and bolts 312 are movably installed on the inner walls of the multiple sets of screw grooves 111. The bolts 312 and screw grooves 111 allow the various components of the sampler to be easily disassembled and reinstalled.

[0034] Working principle: First, the operator holds both sets of operating levers 5 with both hands, and with the help of the comfortable grip and anti-slip performance provided by the rubber sleeves 6, rotates the operating levers 5 to drive the long rod 4 and the connected movable plate 411, the third movable sampling tube 911, the second movable sampling tube 9, and the first movable sampling tube 8 to rotate synchronously. Since these movable sampling tubes are all movably installed in the inner wall of the fixed sampling tube 1, they will gradually penetrate deeper into the soil layer as the fixed sampling tube 1 rotates. When the sampling reaches the predetermined depth, the operator stops rotating the operating levers 5 and gently pulls out the sampler. At this time, the third movable sampling tube 911, the second movable sampling tube 9, and the first movable sampling tube 8 are all filled with soil samples. The operator needs to remove the entire sampler from the soil first. In order to perform the sampling operation, the operator first presses the telescopic pin 211, which retracts into the mounting groove 213 under the elastic force of the spring 212, thereby releasing the locking state between the fixed sampling tube 1 and the limiting tube 3. Next, the operator gently pushes the fixed sampling tube 1, causing it to slide upward along the inner wall of the limiting tube 3, and pushes the movable plate 411 and the movable sampling tube connected to it to detach from the inner wall of the fixed sampling tube 1.

[0035] Since the movable plate 411, the third movable sampling tube 911, the second movable sampling tube 9, and the first movable sampling tube 8 are all interconnected via magnetic grooves 913 and magnetic pins 912, they can be easily separated from the overall structure to form multiple independent soil sample segments. These sample segments retain the original structure and layers of the soil, greatly facilitating subsequent detailed analysis.

[0036] Finally, the operator can use the ejector plate 7 to gently push through the inner walls of the third movable sampling tube 911, the second movable sampling tube 9, and the first movable sampling tube 8 to completely eject the soil sample from the sampling tube. In this way, the operator can independently test and analyze each soil sample segment, thereby more accurately assessing the situation of soil erosion in arable land.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
