Description

Technical Field

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

[0002] Soil sampling in land exploration is a highly technical and specialized task, typically accomplished using equipment such as drilling rigs, samplers, and geological hammers. Taking a sampler as an example, the sampler is vertically aligned with the predetermined depth, and the handles are gripped firmly with both hands. The sampler is then rotated and pressed down, rotating back and forth while applying even pressure. The pressure is adjusted according to the soil's shear strength to maintain its natural structure. Once the predetermined depth is reached, the sampler is gently lifted, the outlet aligned with the sample bag, and the inlet end is gently pressed to allow the sample to slide out. If blockage occurs, a rubber mallet can be used to gently tap the sampler to easily complete the soil sampling. However, existing samplers have limitations in extracting soil from harder strata, reducing sampling efficiency. Therefore, there is an urgent need for a device capable of rapid soil sampling to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a rapid soil sampling device for surveying, in order to solve the problems described in the background art.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A rapid soil sampling device for surveying includes a main control head, a receiving column, and a support unit connected sequentially from top to bottom. The main control head has a built-in first drive motor, and the output end of the first drive motor is connected to a threaded rod. A sliding block is sleeved on the outer circumference of the threaded rod. The receiving column has a built-in cavity, and guide rails are symmetrically arranged on the inner sidewall of the cavity. The two ends of the sliding block extend into the guide rails and are slidably connected. A fixing component is connected to the bottom surface of the sliding block, and a second drive motor is connected to the bottom surface of the fixing component and is coaxially arranged with the first drive motor. The output end of the second drive motor is connected to a sampling element for extending into the stratum.

[0006] A further technical solution is that the bottom end of the receiving column is provided with an extension plate that connects to the support part. When the sampling element is not working, it is suspended between the bottom of the extension plate and the bottom surface of the support part.

[0007] A further technical solution is that the sampling element includes a sampling cylinder, the bottom edge of which is integrally provided with soil-breaking teeth, and the top of the sampling cylinder is connected to the output end of the second drive motor.

[0008] A further technical solution is that the output end of the second drive motor is fixedly provided with a disassembly part to connect the sampling cylinder.

[0009] A further technical solution is that the disassembly part includes a fixed cylinder fixed to the output end of the second drive motor. The top surface of the fixed cylinder is provided with a vertical plate. Elastic components that move horizontally along the front of the vertical plate are symmetrically arranged in front of the vertical plate. The top of the sampling cylinder is provided with a protruding ring. The protruding ring is provided with a locking interface. One end of the elastic component extends out of the fixed cylinder. After the protruding ring is pressed upward, one end of the elastic component is adapted and connected to the locking interface.

[0010] A further technical solution is that the elastic component includes a concave plate, the opening of which is opposite to the inner wall of the fixed cylinder, and a spring is provided on the inner side wall of the opening away from the concave plate. The other end of the spring is connected to an extension plate. The extension plate extends out of the fixed cylinder without external force. After the convex ring is pressed upward, the extension plate compresses the spring, and after the spring releases its elasticity, it extends out of the fixed cylinder and is adapted to connect with the card interface.

[0011] A further technical solution is that the bottom edge of the part of the protruding plate extending out of the fixed cylinder is arc-shaped, and a translation block is provided in the part inside the fixed cylinder. The translation block is connected to the inner side wall of the concave plate through the spring, and the side of the translation block slides and is limited by the upper and lower side walls of the concave plate.

[0012] A further technical solution is that the support part includes a support column and a load-bearing frame, the top end of the support column is connected to the bottom surface of the extension plate, and the bottom end is embeddedly connected to the side of the load-bearing frame.

[0013] A further technical solution is that the side of the load-bearing frame is provided with multiple strip-shaped through holes, which are used to connect external fixing elements and fix them to the ground.

[0014] A further technical solution is that the fixing component includes a fixing rod and a fixing plate. The top end of the fixing rod is fixedly connected to the bottom surface of the sliding block, and the bottom end is connected to the top surface of the fixing plate. The bottom surface of the fixing plate is stably connected to the second drive motor.

[0015] The beneficial effects of this utility model are as follows:

[0016] First, the support unit is placed on the upper surface of the stratum being surveyed, and then a weight is placed on the support unit to improve overall stability. Simultaneously, the first and second drive motors are activated. The first drive motor drives the threaded rod to rotate, allowing the sliding block to engage and drive a linear descent while the threaded rod is rotating. The second drive motor is then moved towards the stratum surface via a fixing component. Once the sampling element touches the stratum surface, the second drive motor continues to rotate, causing the sampling element to quickly break through the soil. Under the downward pressure of the first drive motor, it continues to extend into the stratum. With the first drive motor pressing down and the second drive motor continuously rotating, the soil sample within the stratum is collected by the sampling element, thus solving the technical problem of existing samplers being unable to extract soil from hard strata and reducing soil extraction efficiency.

[0023] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0024] Example 1

[0025] See Figures 1 to 4This utility model provides a rapid soil sampling device for surveying, including a main control head 1, a receiving column 2, and a support part connected sequentially from top to bottom. The main control head 1 has a built-in first drive motor 3, and the output end of the first drive motor 3 is connected to a threaded rod 4. A sliding block 5 is sleeved on the outer circumference of the threaded rod 4. The receiving column 2 has a built-in cavity, and guide rails 6 are symmetrically arranged on the inner sidewall of the cavity. The two ends of the sliding block 5 extend into the guide rails 6 and slide together. A fixing component is connected to the bottom surface of the sliding block 5. A second drive motor 7 is connected to the bottom surface of the fixing component and is coaxially arranged with the first drive motor 3. The output end of the second drive motor 7 is connected to a sampling element for extending into the stratum. An extension plate 8 is provided at the bottom end of the receiving column 2 to connect to the support part.

[0026] It should be noted that the first drive motor 3 and the second drive motor 7 are the same model of motor. The main control head 1 is used to cover the first drive motor 3, providing a certain degree of protection for the first drive motor 3. The receiving column 2 is a circular column, and its inner wall is used to fix the guide rail 6 so that the sliding block 5 can slide stably up and down within the guide rail 6.

[0027] It is worth noting that the second drive motor 7 is coaxially arranged with the first drive motor 3. The second drive motor 7 is also coaxially connected with a sampling element for soil sampling. To a certain extent, the first drive motor 3, the second drive motor 7, and the sampling element are perpendicular to the stratum and extend into the stratum, which plays a certain protective role for the structure of the stratum. At the same time, it ensures the stability of the soil sample taken out, making it easier for staff to compare the soil sample with the standard value and obtain accurate test results.

[0028] Specifically, firstly, the support is placed on the upper surface of the stratum being surveyed, and then a weight is placed on the support to improve overall stability. Simultaneously, the first drive motor 3 and the second drive motor 7 are activated. The first drive motor 3 drives the threaded rod 4 to rotate, allowing the sliding block 5 to engage and descend linearly while the threaded rod 4 is rotating. The second drive motor 7 is then moved towards the stratum surface via a fixing assembly. When the sampling element touches the stratum surface, the second drive motor 7 continues to rotate, causing the sampling element to quickly break through the soil. Under the downward pressure of the first drive motor 3, it continues to extend into the stratum. With the first drive motor 3 pressing down and the second drive motor 7 rotating continuously, the soil sample within the stratum is collected by the sampling element, thus solving the technical problem of existing samplers being unable to extract soil from hard strata and reducing soil extraction efficiency.

[0029] Preferably, the support includes a support column 19 and a load-bearing frame 20. The top end of the support column 19 is connected to the bottom surface of the extension plate 8, and the bottom end is embeddedly connected to the side of the load-bearing frame 20. The side of the load-bearing frame 20 is provided with a plurality of strip-shaped through holes 21, which are used to connect external fixing elements and fix them to the ground.

[0030] When the load-bearing frame 20 is placed on the ground, the weight of the load-bearing frame 20 is increased by stacking heavy objects, which stabilizes the center of gravity of the main control head 1 and the support column 2, facilitating subsequent stable soil extraction work. In addition, the center of gravity of the main control head 1 and the support column 2 can also be stabilized by passing an iron plate through the strip-shaped through hole 21 and then inserting a long screw into the stratum or rock, which is conducive to the subsequent stable soil extraction work.

[0031] Preferably, the fixing assembly includes a fixing rod 22 and a fixing plate 23. The top end of the fixing rod 22 is fixedly connected to the bottom surface of the sliding block 5, and the bottom end is connected to the top surface of the fixing plate 23. The bottom surface of the fixing plate 23 is stably connected to the second drive motor 7.

[0032] The fixing plate 23 is used to fix the second drive motor 7, improving the working stability of the second drive motor 7. At the same time, based on the connecting function of the fixing rod 22, when the sliding block 5 descends, it drives the second drive motor 7 and the sampling element to successfully complete the next step of soil sampling.

[0033] Preferably, the bottom end of the receiving column 2 is provided with an extension plate 8 connecting to the support part. When the sampling element is not working, it is suspended between the bottom of the extension plate 8 and the bottom surface of the support part. The sampling element includes a sampling cylinder 9, the bottom edge of which is integrally provided with soil breaking teeth 10, and the top end of the sampling cylinder 9 is connected to the output end of the second drive motor 7.

[0034] The bottom edge of the sampling cylinder 9 is integrally equipped with soil-breaking teeth 10 to facilitate the rapid breaking of hard soil layers and the insertion into the soil layer to complete the soil sampling work. In addition, when the sampling element is not in operation, the first drive motor 3 drives the threaded rod 4 to slide the second drive motor 7 upward, so that after the sampling element leaves the ground, the soil sample inside the sampling element is taken out, and the sampling cylinder 9 is suspended above the load-bearing frame 20 to prevent the soil-breaking teeth 10 from scratching the floor on which the device is placed.

[0035] Example 2

[0036] See Figures 2 to 4As a further improvement to Embodiment 1, the output end of the second drive motor 7 is fixedly provided with a disassembly part to connect to the sampling cylinder 9. The disassembly part includes a fixed cylinder 11 fixed to the output end of the second drive motor 7. A vertical plate 12 is provided on the inner top surface of the fixed cylinder 11. Elastic components that move horizontally along the front of the vertical plate 12 are symmetrically arranged on the front of the vertical plate 12. A protruding ring 13 is provided at the top of the sampling cylinder 9. The protruding ring 13 is provided with a locking interface 14. One end of the elastic component extends out of the fixed cylinder 11. After the protruding ring 13 is pressed upward, one end of the elastic component is adapted to connect with the locking interface 14. The elastic component includes a concave plate 15, the opening of which is opposite to the inner wall of the fixed cylinder 11. A spring 16 is provided on the inner sidewall away from the opening of the concave plate 15. The other end of the spring 16 is connected to an extension plate 17. The extension plate 17 extends out of the fixed cylinder 11 without external force. After the convex ring 13 presses upward, the extension plate 17 releases its elasticity by compressing the spring 16 and extends out of the fixed cylinder 11 to be fitted and connected to the snap-fit ​​interface 14. The bottom edge of the part of the extension plate 17 extending out of the fixed cylinder 11 is arc-shaped. A translation block 18 is provided in the part inside the fixed cylinder 11. The translation block 18 is connected to the inner sidewall of the concave plate 15 through the spring 16. The side of the translation block 18 slides and is limited by the upper and lower sidewalls of the inner sidewall of the concave plate 15.

[0037] When it is necessary to replace the sampling tube 9 or remove the soil sample from the sampling tube 9, the sampling tube 9 can be removed through the disassembly section.

[0038] For example, by pressing the end of the protruding plate 17 with specific clamps, the protruding plate 17 moves the spring 16 towards the inner wall and compresses the spring 16. At the same time, the translation block 18 slides and limits the upper and lower side walls of the concave plate 15 to prevent the protruding plate 17 from popping out and affecting the normal workflow. When the protruding end of the protruding plate 17 is fully pressed into the fixed cylinder 11, the convex ring 13 is disengaged from the fixed cylinder 11, completing the disassembly work. At this time, the potential energy stored in the spring 16 restores the spring 16 to its original shape, so that the arc-shaped part of the protruding plate 17 protrudes out of the fixed cylinder 11 again.

[0039] Similarly, when the protruding ring 13 is pressed upward, the top of the protruding ring 13 contacts the arc-shaped surface of the protruding plate 17. After the protruding plate 17 is pressed upward with force, the arc-shaped surface moves the protruding plate 17 into the fixed cylinder 11 under the action of the pressing force. At the same time, the translation block 18 is pressed against the upper and lower side walls of the concave frame to limit the movement, while the spring 16 is pressed towards the vertical side wall of the concave plate 15. It is also known that the locking interface 14 of the protruding ring 13 is higher than the top surface of the protruding plate 17, so that the protruding plate 17 is ejected by the spring 16 without the action of external force and locks the locking interface 14, thus completing the connection between the protruding ring 13 and the fixed cylinder 11, which facilitates the stable rotation of the sampling cylinder 9 by the second drive motor 7 to realize the soil sampling function.

[0040] In addition, the vertical plate 12 is used to set the concave plate 15 and, together with the concave plate 15, stably connects the protruding plate 17, ensuring the stability of the connection between the convex ring 13 and the fixed cylinder 11, which is conducive to the sampling cylinder 9 stably completing the soil sampling work.

[0041] It is worth noting that the width of the inner wall of the card interface 14 is adapted to fit the width of the outer wall of the protruding plate 17 and has a friction surface, making the connection between the card interface 14 and the protruding plate 17 more stable. In addition, the diameter of the convex ring 13 is 1 / 3 of the diameter of the sampling cylinder 9, so that the formation structure cannot touch the protruding plate 17 when the sampling cylinder 9 is working, ensuring a stable connection between the convex ring 13 and the fixed cylinder 11.

[0042] It is worth noting that the spring 16 is a spring with a large elastic coefficient. A light force cannot compress the spring 16, thereby ensuring that when the spring 16 drives the extension plate 17, the engagement stability between the extension plate 17 and the card interface 14 is improved.

[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.
