Description

Technical Field

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

[0002] Soil and water conservation monitoring sampling is a core step in obtaining key data on soil erosion by collecting soil, runoff, sediment, and vegetation samples using scientific methods. It directly determines the accuracy of monitoring and assessment results. By collecting soil samples from different soil layers and analyzing indicators such as bulk density, moisture content, and organic matter content, it is possible to determine whether soil erosion leads to soil degradation, as well as the speed and extent of degradation, thus providing data reference for soil protection.

[0003] For example, a sampling device for soil and water conservation monitoring with publication number CN222280188U can quickly remove the disassembly plate from the first installation slot by means of an inserted disassembly plate, a limit pin, a fixed plate, a movable plate, an insert block, and a top block. This allows soil samples at different depths in the soil layer to be completely extracted from the soil sampling tube, improving the convenience of soil sample extraction and the accuracy of soil sample data monitoring. However, the location of the soil extracted in this way changes each time, resulting in the test results not showing the changes of the same soil in each test. Utility Model Content

[0004] The purpose of this invention is to provide a sampling device for soil and water conservation monitoring to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for soil and water conservation monitoring, comprising a pre-embedded cylinder, a sleeve movably fitted onto the inner wall of the pre-embedded cylinder, an insert rod inserted into the inside of the sleeve, a rotating rod fixedly connected to the upper end of the insert rod, an elliptical block fixedly connected to the lower end of the insert rod, a collar movably fitted onto the outer wall of the elliptical block, a connecting rod fixedly connected to the upper surface of the collar, the upper end of the connecting rod fixedly connected to the lower surface of the insert rod, two hooks fixedly connected to the lower surface of the collar, a fixing rod engaged inside the hooks, and round caps fixedly connected to both ends of the fixing rod, an opening on one side of the lower surface of the round cap, and a cutter fixedly connected to the inner wall of the opening.

[0006] Preferably, two fixing plates are fixedly connected to the upper outer wall of the pre-embedded cylinder, and a cover plate is hinged to one side of the fixing plate.

[0007] Preferably, the round cover is movably sleeved on the lower end of the inner wall of the pre-embedded cylinder, and the round cover corresponds to the collar.

[0008] Preferably, the outer wall of the elliptical block matches the inner wall of the collar, and the elliptical block corresponds to the fixing rod.

[0009] Preferably, the length of the hook is shorter than the thickness of the elliptical block.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] (1) By fixing the sampling position through the pre-embedded cylinder, each sampling comes from the same soil area, and the changes in soil indicators at different time points can be directly compared, avoiding the data deviation caused by the sampling position shift of traditional devices. Through the linkage of mechanical structures such as rotating rod and elliptical block, the opening and closing of the round cover and soil cutting can be controlled by rotating the rotating rod, without complicated disassembly and assembly, reducing the difficulty of operation.

[0012] (2) The cutter at the opening of the round cap can quickly cut the soil, reduce the damage to the soil structure during the sampling process, and at the same time the round cap can protect the sample from falling during the extraction process, thus improving the sample quality.

[0019] 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.

[0020] Please see Figure 1-5 The present invention provides the following technical solution:

[0021] Example 1: A sampling device for soil and water conservation monitoring includes a pre-embedded cylinder 1. A sleeve 2 is movably sleeved on the inner wall of the pre-embedded cylinder 1. An insert rod 3 is inserted into the sleeve 2. A rotating rod 4 is fixedly connected to the upper end of the insert rod 3. An elliptical block 5 is fixedly connected to the lower end of the insert rod 3. A collar 6 is movably sleeved on the outer wall of the elliptical block 5. A connecting rod 7 is fixedly connected to the upper surface of the collar 6. The upper end of the connecting rod 7 is fixedly connected to the lower surface of the insert rod 3. Two hooks 8 are fixedly connected to the lower surface of the collar 6. A fixing rod 10 is snapped into the inside of the hooks 8. A round cover 9 is fixedly connected to both ends of the fixing rod 10. An opening 11 is opened on one side of the lower surface of the round cover 9. A cutter 12 is fixedly connected to the inner wall of the opening 11.

[0022] Two fixing plates 13 are fixedly connected to the upper outer wall of the pre-embedded cylinder 1. A cover plate 14 is hinged to one side of the fixing plate 13. Closing the cover plate 14 can ensure that the soil inside the pre-embedded cylinder 1 is not affected by the pre-embedded cylinder 1.

[0023] The round cover 9 is movably sleeved on the lower end of the inner wall of the pre-embedded cylinder 1. The round cover 9 corresponds to the collar 6, so that the round cover 9 can be stably locked at the lower end of the collar 6, and at the same time, the round cover 9 can slide stably in the pre-embedded cylinder 1.

[0024] The outer wall of the elliptical block 5 matches the inner wall of the collar 6, and the elliptical block 5 corresponds to the fixed rod 10, so that the elliptical block 5 can drive the collar 6 to rotate.

[0025] The length of hook 8 is shorter than the thickness of elliptical block 5, so that elliptical block 5 remains stuck in collar 6 when it abuts against fixing rod 10.

[0026] In use, first, vertically bury the pre-embedded cylinder 1 into the soil to be monitored, ensuring that the lower end of the pre-embedded cylinder 1 penetrates deep into the target soil layer and the upper end is flush with the ground. Then, snap the round cap 9 into the bottom of the collar 6, so that the hook 8 and the fixing rod 10 are engaged. Then, push the insertion rod 3 to move the elliptical block 5 against the upper end of the fixing rod 10, so that the hook 8 and the fixing rod 10 are fixed. Then, fix the round cap 9 to the lower end of the collar 6. When sampling, press down and rotate the rotating rod 4 to drive the insertion rod 3 and the elliptical block 5 to rotate and move downward synchronously, so that the round cap 9 is subjected to pressure and rotates downward. When the soil is removed from the lower end of the pre-embedded cylinder 1, the cutter 12 at the opening on the lower surface of the round cover 9 cuts the soil in contact, allowing the soil to enter the interior of the round cover 9. Then, the rotating rod 4 is pulled back to move the round cover 9 out of the pre-embedded cylinder 1. At this time, the round cover 9 is pushed to move the fixing rod 10 out of the hook 8, and the round cover 9 can be removed from the lower end of the collar 6. The soil removed from the round cover 9 each time is from the same soil area, and the changes in soil indicators at different time points can be directly compared. Finally, closing the cover plate 14 can ensure that the soil inside the pre-embedded cylinder 1 is not affected by the pre-embedded cylinder 1.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
