Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a double-tube soil sampling device. Background Art

[0002] Soil sampling is the process of collecting soil samples from the surface or underground through specific tools (such as soil drills or samplers). These samples can be used for environmental monitoring, geological exploration, agricultural assessment, etc. to analyze the physical, chemical, and biological properties of the soil, help evaluate soil quality, pollution degree, or suitability, thus supporting scientific research and decision-making.

[0003] During the existing soil sampling operation, generally, a double-tube soil sampling system is placed under the hydraulic hammer at the front end of the drill rig. The sampling system is directly pushed into the ground under the vertical static pressure of the hydraulic hammer, and soil samples can be continuously taken out in an uninterrupted continuous column, thus realizing the operation of soil sampling. However, the sites for soil sampling are generally not very flat, resulting in the deviation or inclination of the device during the sampling process, so that the sampling system cannot be vertically pushed into the ground, resulting in inaccurate or uneven depths of the collected soil samples. In view of the above problems, the technical personnel in this field have proposed a double-tube soil sampling device to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a double-tube soil sampling device, aiming to improve the problem that during sampling by the existing sampling device, due to the uneven ground, the sampling system cannot be vertically pushed into the ground, resulting in inaccurate or uneven depths of the collected soil samples.

[0007] Further, the disassembly component includes two limiting grooves which are respectively arranged on the left and right sides inside the mounting plate. A limiting plate is slidably connected inside the limiting groove. One side of the limiting plate is rotatably connected with a bolt, and the other side of the limiting plate is rotatably connected with two connecting rods. The other ends of the connecting rods are rotatably connected with a clamping block. Two clamping grooves are respectively arranged on the left and right sides of the fixing plate.

[0008] Further, the inside of the slider is slidably connected with the outside of the sliding rod, and the other end of the support rod is rotatably connected to the bottom of the support plate.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Referring to Figure 1 and Figure 2 A double-tube soil sampling device provided by the present utility model includes a moving seat 1. A fixed frame 2 is fixedly connected to the top of the moving seat 1. A rack plate 3 is fixedly connected to the inside of the fixed frame 2. A mounting seat 4 is slidably connected to the outside of the rack plate 3. A motor 6 is installed on the top of the mounting seat 4. The output end of the motor 6 penetrates through the inner wall of the mounting seat 4 and is fixedly connected to a gear 5. Connecting rods 7 are fixedly connected to both sides of the outside of the mounting seat 4. One end of the connecting rod 7 is fixedly connected to a slide block 8. A support rod 24 is rotatably connected to the top of the slide block 8. Fixed seats 9 are fixedly connected to both sides of the top of the moving seat 1 and inside the fixed frame 2. A slide rod 11 is fixedly connected to the inside of the fixed seat 9. The inside of the slide block 8 is slidably connected to the outside of the slide rod 11. The other end of the support rod 24 is rotatably connected to the bottom of the support plate 12. The outside of the gear 5 is meshed with the outside of the rack plate 3. The outside of the mounting seat 4 is slidably connected to the inside of the fixed frame 2.

[0023] Specifically, the moving seat 1 supports and fixes the fixed frame 2, and then fixes the rack plate 3 inside the fixed frame 2. When the motor 6 operates to drive the gear 5 to rotate, and the gear 5 meshes with the rack plate 3, the mounting seat 4 can slide inside the fixed frame 2. In this way, the connecting rods 7 connected on both sides can be driven to move. The connecting rod 7 drives the slider 8 to slide along the slide rod 11. The moving seat 1 fixes the two fixed seats 9, and the slide rod 11 guides the movement of the slider 8 to keep it moving horizontally. The slider 8 can drive one end of the support rod 24 to move, so that the support rod 24 pushes the support plate 12 to rotate around the support column 10, and the support plate 12 can be adjusted to a horizontal state, so that the double-tube body 16 can be vertically inserted into the soil during sampling, avoiding skew or depth measurement errors caused by instability, thereby improving the accuracy and reliability of sampling.

[0024] Referring to Figure 1 , on the left side of the top of the moving seat 1, there is a fixed connection with a support column 10. The top of the support column 10 is rotatably connected to a support plate 12. The top of the support plate 12 is fixedly connected to a support frame 13. A hydraulic cylinder 14 is installed on the top of the support frame 13. The output end of the hydraulic cylinder 14 is fixedly connected to a fixing plate 17. An installation plate 15 is installed outside the fixing plate 17 through a disassembly component. The disassembly component is used for installing and disassembling the installation plate 15. The bottom of the fixing plate 17 is fixedly connected to a double-tube body 16, and a conical drill bit is arranged at the bottom of the double-tube body 16.

[0025] Specifically, the support column 10 supports the support plate 12, so that the support plate 12 can rotate during leveling. The support plate 12 supports and fixes the support frame 13, and then the hydraulic cylinder 14 installed on the top can push the fixing plate 17 to move. The fixing plate 17 can drive the installation plate 15 to move, and then apply pressure to the double-tube body 16 to insert it into the soil to realize the operation of soil sampling. The conical drill bit fixed at the bottom of the double-tube body 16 can better insert into the soil. The double-tube body 16 has an inner tube and an outer tube respectively. Sampling is carried out through the inner tube, and the outer tube protects the inner tube so that the sampled soil will not be contaminated.

[0026] Referring to Figure 3, the disassembly component includes two limit slots 18 which are respectively arranged on the left and right sides inside the mounting plate 15. A limit plate 20 is slidably connected inside the limit slot 18. One side of the limit plate 20 is rotatably connected to a bolt 19, and the other side of the limit plate 20 is rotatably connected to two connecting rods 21. The other ends of the connecting rods 21 are rotatably connected to a clamping block 22. Two clamping slots 23 are respectively arranged on the left and right sides of the fixing plate 17. One end of the bolt 19 extends to the outside of the mounting plate 15, and the bolt 19 is threadedly connected to the inside of the mounting plate 15. The clamping block 22 is engaged with the inside of the adjacent clamping slot 23, and the clamping block 22 is slidably connected inside the limit slot 18.

[0027] Specifically, by rotating the bolt 19, the limit plate 20 can be pushed to move inside the limit slot 18, and then the limit plate 20 drives the connecting rods 21 at both ends to move, so that the clamping block 22 can be driven to disengage from the clamping slot 23, and thus the fixing plate 17 can be disassembled from the mounting plate 15. Without the aid of tools, the disassembly and assembly of the double-tube body 16 can be realized, improving the disassembly and assembly efficiency and reducing the maintenance cost. The limit slot 18 restricts the movement of the limit plate 20 to keep it moving horizontally.

[0028] Working principle: When using this device, the moving seat 1 is driven by the driving device to move to the position where soil sampling is required. Then, the motor 6 runs to drive the gear 5 to rotate, and then the mounting seat 4 slides inside the fixed frame 2, driving the connecting rods 7 connected on both sides to move. The connecting rod 7 drives the slider 8 to slide along the slide rod 11, and one end of the support rod 24 can be driven to move, so that the support rod 24 pushes the support plate 12 to rotate around the support column 10, adjusting the support plate 12 to a horizontal state, so that the double-tube body 16 can be vertically inserted into the soil during sampling, avoiding deflection or depth measurement errors caused by instability, thereby improving the accuracy and reliability of sampling. The hydraulic cylinder 14 is used to push the fixing plate 17 to move, and then drive the mounting plate 15 to move, so as to apply pressure to the double-tube body 16 to insert it into the soil to complete the sampling operation. Among them, by rotating the bolts 19 on both sides of the mounting plate 15, the bolts 19 can be pushed to move the limit plate 20, and then drive the connecting rods 21 to move, so that the clamping block 22 can be driven to disengage from the clamping slot 23. At this time, the fixing plate 17 can be disassembled from the mounting plate 15. Without the aid of tools, the disassembly and assembly of the double-tube body 16 can be realized, improving the disassembly and assembly efficiency and reducing the maintenance cost.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
