Description

Technical Field

[0001] This utility model relates to the field of water and soil management sampling technology, and more specifically, to a continuous detection sampler. Background Technology

[0002] Currently, soil erosion is a critical issue that has attracted much attention and urgently needs to be addressed. It not only damages land resources, reduces soil fertility, and affects agricultural production, but also causes a series of environmental problems such as river siltation, water turbidity, and ecosystem imbalance. In order to effectively control soil erosion, relevant indicators such as the sand content of soil or silt serve as important criteria for measuring the status of soil erosion. Therefore, it is necessary to use a sampler to sample soil or silt.

[0003] However, most existing samplers require manual sampling, have low sampling efficiency, and cannot perform continuous automatic sampling.

[0004] For example, Chinese patent CN217237313U discloses a continuous sampler for soil and water conservation monitoring. This structure can facilitate automatic and continuous sampling, with higher sampling efficiency and easier use.

[0005] However, in actual use, this sampler uses a motor to drive a rotating shaft and a spiral blade to rotate inside the sampling cylinder to achieve the purpose of sampling. However, the rotating shaft and spiral blade are difficult to extend out from the inside of the sampling cylinder, making it difficult to clean the mud and sand inside the sampling cylinder as well as the mud and sand on the surface of the rotating shaft and spiral blade. Moreover, once the spiral blade is worn, it is difficult to perform maintenance operations, affecting the service life of the equipment. In view of this, this utility model proposes a continuous detection sampler. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a continuous detection sampler to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a continuous detection sampler, comprising two support frames, a support plate disposed between the two support frames, a sampling cylinder fixedly embedded in the center of the surface of the support plate, a sealing cap mounted on the top of the sampling cylinder, a drive motor fixedly mounted on the sealing cap, a rotating shaft fixedly mounted on the output end of the drive motor, a spiral blade fixedly mounted on the outside of the rotating shaft, both the rotating shaft and the spiral blade being located inside the sampling cylinder, and a discharge port penetrating through the outer wall of the top of the sampling cylinder.

[0008] As can be seen from the above structure, the drive motor drives the rotating shaft and spiral blades to rotate inside the sampling tube, which enables the soil or mud to be discharged through the discharge port of the sampling tube, thus achieving the purpose of sampling.

[0009] To facilitate the extension of the rotating shaft and spiral blades from the inside of the sampling cylinder, enabling convenient subsequent cleaning and maintenance and extending the equipment's lifespan, preferably, the surface of the support plate at the sealing cover is provided with a lifting structure. This lifting structure includes two mounting brackets, both fixedly mounted on the surface of the support plate and located on opposite sides of the sealing cover. A lead screw is rotatably mounted inside one mounting bracket, while a sliding rod is fixedly mounted inside the other. A threaded block and a slider are respectively mounted on the outside of the lead screw and the sliding rod. A first servo motor is mounted at the top of the lead screw, fixedly mounted on the top of the corresponding mounting bracket, and its output end is fixedly connected to the lead screw. The threaded block is threaded onto the outside of the lead screw, and the slider is slidably connected to the sliding rod. Both the threaded block and the slider are fixedly connected to the outer wall of the sealing cover.

[0010] To facilitate sampling of soil and silt at different depths, preferably, the inner walls of both support frames are provided with mounting grooves. A screw is rotatably mounted inside one mounting groove, and a guide rod is fixedly mounted inside the other mounting groove. A moving block and a guide block are respectively provided on the outside of the screw and the guide rod. A second servo motor is fixedly mounted on the top of the screw and is fixedly mounted on the top of the corresponding support frame. The output end of the second servo motor is fixedly connected to the screw. The moving block is mounted on the outside of the screw and is threadedly connected to the screw. The guide block is slidably connected to the guide rod. The moving block and the guide block are respectively fixedly mounted on both ends of the support plate.

[0011] To store mud and sand samples taken at different depths separately for continuous sampling and testing, preferably, a toothed ring is rotatably mounted on the surface of the sampling cylinder above the support plate. A rotating disk is fixedly mounted on the top of the toothed ring and rotatably connected to the outer wall of the sampling cylinder. A gear meshes with one side of the toothed ring, and a rotary motor is mounted at the bottom of the gear. The rotary motor is fixedly embedded in the surface of the support plate, and its output end is fixedly connected to the gear. An arc-shaped groove is formed on the outer wall of the sampling cylinder near the toothed ring, and the toothed ring is rotatably connected and embedded inside the arc-shaped groove. Multiple circular grooves are formed on the inner wall of the toothed ring, and ball bearings are rolled inside each of the multiple circular grooves. Several sample boxes are mounted on the rotating disk.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a lifting structure, the first servo motor drives the lead screw to rotate, which enables the threaded block to drive the sealing cover to move upward through the slider outside the slide rod. The sealing cover drives the rotating shaft and spiral blade to extend from the inside of the sampling cylinder to the outside. After the rotating shaft and spiral blade extend out, it is convenient to wash the mud or sand adhering to the inner wall of the sampling cylinder, and it is also convenient to clean and maintain the rotating shaft and spiral blade, thereby improving the service life of the equipment.

[0014] 2. The second servo motor drives the screw to rotate inside the corresponding mounting slot, so that the moving block drives the support plate to adjust up and down between the two support frames through the guide block and guide rod. The support plate can drive the sampling cylinder to adjust up and down, which facilitates sampling operations on soil or mud and sand at different depths and improves the sampling range.

[0015] 3. The rotating motor drives the gear to rotate, which in turn drives the gear ring to rotate on the outer wall of the sampling cylinder, thereby driving the rotating disk to rotate on the outer wall of the sampling cylinder. Multiple sample boxes can be rotated one by one to the bottom of the discharge port for storing soil or mud at different depths, achieving the purpose of continuous testing and sampling. Moreover, during the rotation of the gear ring inside the arc groove of the sampling cylinder, multiple balls will rotate inside the circular groove, which can ensure the smoothness of the gear ring rotation and reduce jamming.

[0023] 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.

[0024] As attached Figure 1-6 The continuous detection sampler shown includes two support frames 1, with a support plate 2 between the two support frames 1. A sampling cylinder 3 is fixedly embedded in the center of the surface of the support plate 2. A sealing cover 4 is installed at the top of the sampling cylinder 3. A drive motor 5 is fixedly installed on the sealing cover 4. A rotating shaft 6 is fixedly installed at the output end of the drive motor 5. A spiral blade 7 is fixedly installed on the outside of the rotating shaft 6. Both the rotating shaft 6 and the spiral blade 7 are located inside the sampling cylinder 3. A discharge port 27 is penetratingly connected to the outer wall of the top of the sampling cylinder 3.

[0025] Specifically, in this structure, when soil or silt needs to be sampled and tested for soil erosion control, firstly, two support frames 1 support the support plate 2, and the support plate 2 supports the sampling cylinder 3. After the sampling cylinder 3 is extended to the soil part that needs to be sampled, the drive motor 5 on the sealing cover 4 drives the rotating shaft 6 and the spiral blade 7 to rotate, so that the soil or silt is discharged through the discharge port 27 of the sampling cylinder 3, thus achieving the purpose of sampling.

[0026] In a specific embodiment, as shown in the appendix Figure 1 , 3As shown, a lifting structure is provided on the surface of the support plate 2 at the sealing cover 4. The lifting structure includes two mounting brackets 8, both of which are fixedly installed on the surface of the support plate 2 and located on both sides of the sealing cover 4. A lead screw 9 is rotatably installed inside one mounting bracket 8, and a slide rod 10 is fixedly installed inside the other mounting bracket 8. A threaded block 11 and a slider 12 are respectively installed on the outside of the lead screw 9 and the slide rod 10. A first servo motor 13 is provided at the top of the lead screw 9. The first servo motor 13 is fixedly installed at the top of the corresponding mounting bracket 8, and the output end of the first servo motor 13 is fixedly connected to the lead screw 9. The threaded block 11 is threadedly connected to the outside of the lead screw 9, and the slider 12 is slidably connected to the slide rod 10. Both the threaded block 11 and the slider 12 are fixedly connected to the outer wall of the sealing cover 4.

[0027] Specifically, in this structure, the sealing cover 4 is located at the top of the sampling cylinder 3, and the drive motor 5 is installed on the surface of the sealing cover 4. The rotating shaft 6 connected to the spiral blade 7 is fixedly connected to the output end of the drive motor 5. Thus, when it is necessary to clean the soil or sand inside the sampling cylinder 3, or in other words, when it is necessary to clean and maintain the spiral blade 7.

[0028] The first servo motor 13 drives the lead screw 9 to rotate inside the corresponding mounting bracket 8, so that the threaded block 11 drives the sealing cover 4 to move upward through the slider 12 outside the slide rod 10. The sealing cover 4 is disengaged from the top of the sampling cylinder 3, which in turn drives the drive motor 5, the rotating shaft 6 and the spiral blade 7 to extend upward, so that the rotating shaft 6 and the spiral blade 7 extend from the inside of the sampling cylinder 3 to the outside.

[0029] After the rotating shaft 6 and the spiral blade 7 extend out, it is convenient to wash the mud or sand adhering to the inner wall of the sampling cylinder 3, and it is also convenient to clean and maintain the rotating shaft 6 and the spiral blade 7, thereby improving the service life of the equipment.

[0030] After cleaning, the same method is used to extend the rotating shaft 6 and the spiral blade 7 back into the interior of the sampling cylinder 3, and the top of the sampling cylinder 3 is sealed by the sealing cap 4.

[0031] In a specific embodiment, as shown in the appendix Figure 1 , 2As shown, both support frames 1 have mounting grooves 14 on their inner walls. A screw 15 is rotatably mounted inside one mounting groove 14, and a guide rod 16 is fixedly mounted inside the other mounting groove 14. A moving block 17 and a guide block 18 are respectively provided on the outside of the screw 15 and the guide rod 16. A second servo motor 19 is fixedly mounted on the top of the screw 15. The second servo motor 19 is fixedly mounted on the top of the corresponding support frame 1, and the output end of the second servo motor 19 is fixedly connected to the screw 15. The moving block 17 is mounted on the outside of the screw 15 and is threadedly connected to the screw 15. The guide block 18 is slidably connected to the guide rod 16. The moving block 17 and the guide block 18 are respectively fixedly mounted on both ends of the support plate 2.

[0032] Specifically, in this structure, the second servo motor 19 can drive the screw 15 to rotate inside the corresponding mounting slot 14, so that the moving block 17 drives the support plate 2 to be adjusted up and down between the two support frames 1 through the guide block 18 and the guide rod 16. The support plate 2 can drive the sampling cylinder 3 to be adjusted up and down, which facilitates the sampling operation of soil or mud at different depths and improves the sampling range.

[0033] In a specific embodiment, as shown in the appendix Figure 1 , 4 As shown in Figures 5 and 6, a toothed ring 20 is rotatably mounted on the surface of the sampling cylinder 3 above the support plate 2. A rotating disk 21 is fixedly mounted on the top of the toothed ring 20. The rotating disk 21 is rotatably connected to the outer wall of the sampling cylinder 3. A gear 22 is meshed on one side of the toothed ring 20, and a rotary motor 23 is provided at the bottom of the gear 22. The rotary motor 23 is fixedly embedded in the surface of the support plate 2, and the output end of the rotary motor 23 is fixedly connected to the gear 22. An arc-shaped groove 24 is opened on the outer wall of the sampling cylinder 3 near the toothed ring 20. The toothed ring 20 is rotatably connected and embedded in the arc-shaped groove 24. Multiple circular grooves are opened on the inner wall of the toothed ring 20 in an annular shape. Ball bearings 25 are rolled inside the multiple circular grooves. Several sample boxes 26 are installed on the rotating disk 21.

[0034] Specifically, in this structure, multiple sampling boxes 26 are installed on a rotating disk 21 to store soil or mud samples taken at different depths. First, when the sampled soil or mud falls into the corresponding sampling box 26 through the discharge port 27 of the sampling cylinder 3, the rotary motor 23 embedded in the surface of the support plate 2 drives the gear 22 to rotate, so that the gear 22 drives the gear ring 20 to rotate on the outer wall of the sampling cylinder 3, and then drives the rotating disk 21 to rotate on the outer wall of the sampling cylinder 3. Multiple sampling boxes 26 can be rotated one by one to the bottom of the discharge port 27 to store soil or mud at different depths, so as to achieve the purpose of continuous detection and sampling.

[0035] As the toothed ring 20 rotates inside the arc-shaped groove 24 of the sampling cylinder 3, multiple balls 25 rotate inside the circular groove, ensuring the smoothness of the toothed ring 20's rotation and reducing jamming.

[0036] Working principle of this utility model:

[0037] This application provides a continuous detection sampler for sampling and testing soil or mud and sand in soil and water conservation operations. In specific operation, the operator first places the sampler at the location where sampling is required and extends the sampling tube 3 into the soil or mud and sand to be sampled. At this time, the drive motor 5 on the sealing cover 4 drives the rotating shaft 6 and the spiral blade 7 to rotate, so that the soil or mud and sand is discharged through the discharge port 27 of the sampling tube 3, thereby achieving the purpose of sampling.

[0038] During the sampling process, the second servo motor 19 drives the screw 15 to rotate inside the corresponding mounting slot 14 as needed, so that the moving block 17 drives the support plate 2 to adjust up and down between the two support frames 1 through the guide block 18 and the guide rod 16. The support plate 2 can drive the sampling cylinder 3 to adjust up and down, which facilitates sampling operations on soil or mud and sand at different depths and improves the sampling range.

[0039] After sampling, the soil or sand falls into the corresponding sampling box 26 through the discharge port 27 of the sampling cylinder 3 for collection. The rotary motor 23 can drive the gear 22 to rotate, which in turn drives the gear ring 20 to rotate on the outer wall of the sampling cylinder 3, thereby driving the rotating disk 21 to rotate on the outer wall of the sampling cylinder 3. Multiple sampling boxes 26 can be rotated one by one to the bottom of the discharge port 27 for storing soil or sand at different depths, so as to achieve the purpose of continuous testing and sampling.

[0040] After the equipment is used, the first servo motor 13 drives the lead screw 9 to rotate inside the corresponding mounting bracket 8, so that the threaded block 11 drives the sealing cover 4 to move upward through the slider 12 outside the slide rod 10. The sealing cover 4 is disengaged from the top of the sampling cylinder 3, which in turn drives the drive motor 5, the rotating shaft 6 and the spiral blade 7 to extend upward, so that the rotating shaft 6 and the spiral blade 7 extend from the inside of the sampling cylinder 3 to the outside. When the rotating shaft 6 and the spiral blade 7 extend out, it is convenient to wash the mud or sand attached to the inner wall of the sampling cylinder 3, and it is also convenient to clean and maintain the rotating shaft 6 and the spiral blade 7, thereby improving the service life of the equipment.

[0041] After cleaning, the same method is used to extend the rotating shaft 6 and the spiral blade 7 back into the interior of the sampling cylinder 3, and the top of the sampling cylinder 3 is sealed with the sealing cap 4, ready for the next use.

[0042] It should be noted that all contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used. Electrical control components not mentioned in this technical solution are existing technologies and are therefore not shown in the figures, and will not be described here.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
