Description

Technical Field

[0001] The utility model relates to the field of geotechnical exploration sand samplers, and specifically to a new type of geotechnical exploration sand sampler. Background Technique

[0002] The new type of geotechnical exploration sand sampler is used to lift the undisturbed soil of the lower-layer test soil as a sample to understand its properties. In order to better understand the properties of the base layer, and in engineering geological exploration and survey work, in order to obtain the physical and mechanical property indexes of the foundation soil, sometimes it is even necessary to take undisturbed soil at a relatively deep depth, and this kind of soil sampling equipment is called a soil sampler.

[0003] The existing new type of geotechnical exploration sand sampler uses a sand leakage prevention device and an elastic plate on the mounting ring to ensure the integrity and quality of the taken sand sample, providing an accurate data basis for subsequent geotechnical exploration and analysis. However, during the actual use of the geotechnical exploration sand sampler, due to the internal capacity of the sand sampler being a certain amount, when conducting quantitative sampling, the fixed-form sampler is not convenient for quantitative sampling, reducing the sampling accuracy of the geotechnical exploration sand sampler, and further reducing the use convenience of the geotechnical exploration sand sampler. Therefore, there is an urgent need to design a geotechnical exploration sand sampler that can perform quantitative sampling. Content of the Utility Model

[0004] Based on this, the purpose of the present utility model is to provide a new type of geotechnical exploration sand sampler to solve the technical problem that the geotechnical exploration sand sampler is not good at quantitative sampling.

[0005] To achieve the above object, the present utility model provides the following technical solution: A new type of geotechnical exploration sand sampler, including a first outer shell and a second outer shell. The upper and lower ends of the first outer shell and the second outer shell are respectively connected to a first connection cover and a second connection cover. A screw rod is provided on the first connection cover. A limiting plate is provided at the bottom of the screw rod. A hexagonal nut is provided on the outer side of the screw rod.

[0006] By adopting the above technical solution, first, the two ends of the first outer shell and the second outer shell are respectively installed through the first connection cover and the second connection cover. This split type is convenient for the assembly, disassembly and carrying of the sand sampler, significantly improving the use convenience. At the same time, an external tool is used to apply a rotational force to the hexagonal nut, so that the screw rod rotates. During this process, through the threaded connection between the screw rod and the connecting block, the longitudinal position movement of the limiting plate can be effectively promoted, enabling the sand sampler to adapt to different environments and meet various sampling standards. Specifically, by flexibly adjusting the longitudinal position of the limiting plate, the size of the geotechnical sampling area formed between it and the first outer shell and the second outer shell can be changed, so that the operator can accurately control the sampling amount of the geotechnical soil.

[0007] Furthermore, the top of the hexagonal nut is provided on the connecting rod for connecting with an external impact tool.

[0008] By adopting the above technical solution, the setting of the connecting rod enables the hexagonal nut to be conveniently connected with an external impact tool, simplifies the sampling operation process, and improves work efficiency.

[0009] Furthermore, the cross-sections of the first outer shell and the second outer shell are both semi-circular structures.

[0010] By adopting the above technical solution, the semi-circular structure enables the first outer shell and the second outer shell to be conveniently closed and separated, simplifies the assembly and disassembly process of the sand sampler, and improves the operation convenience.

[0011] Furthermore, a connecting block is provided on the top of the first connecting cover, and the connecting block is threadedly connected to the screw rod.

[0012] By adopting the above technical solution, a firm connection between the screw rod and the connecting block is ensured. The threaded connection method has good self-locking property, can effectively prevent the screw rod from loosening or falling off during operation, and thus improves the safety and reliability of the equipment.

[0013] Furthermore, the bottom of the screw rod is threadedly connected with a mounting block, and the limiting plate is detachably structured with the screw rod through the mounting block.

[0014] By adopting the above technical solution, through threaded connection, the mounting block can be conveniently connected to the screw rod, thereby making the installation and disassembly of the limiting plate simple and fast.

[0015] Furthermore, the limiting plate is rotatably connected to the mounting block through a thrust bearing.

[0016] By adopting the above technical solution, this connection method enables the limiting plate to freely rotate on the mounting block, thereby reducing friction and resistance, making the screw rod more smooth when adjusting the position of the limiting plate, and improving the operation efficiency.

[0017] Furthermore, the limiting plate is in a disc-shaped structure, and the limiting plate is in contact with the inner walls of the first outer shell and the second outer shell.

[0018] By adopting the above technical solution, the disc-shaped structure enables the limiting plate to better fit the inner wall of the outer shell, effectively prevents the geotechnical sample from leaking out from the side during sampling, and ensures the accuracy and integrity of sampling.

[0019] In summary, the present utility model mainly has the following beneficial effects:

[0020] The utility model uses a limiting plate. First, the two ends of the first outer shell and the second outer shell are installed through the first connection cover and the second connection cover. This split design facilitates the assembly, disassembly, and carrying of the sand sampler, improving the convenience of use. At the same time, by using a tool to rotate the hexagonal nut, the screw rod rotates, and then through the threaded connection between the screw rod and the connection block, the limiting plate is driven to move longitudinally, enabling the sand sampler to adapt to different environments and sampling standards. By adjusting the position of the limiting plate, the size of the geotechnical sampling area can be changed, thereby precisely controlling the geotechnical sampling volume and enhancing the functional practicability and environmental adaptability of the sand sampler.

[0029] The following will describe the embodiments of the present utility model according to its overall structure. Embodiment 1:

[0030] A new type of geotechnical exploration sand sampler, as Figures 1-4 shown, includes a first outer shell 101 and a second outer shell 102. The upper and lower ends of the first outer shell 101 and the second outer shell 102 are respectively connected to a first connection cover 6 and a second connection cover 7. A screw rod 2 is provided on the first connection cover 6. A limiting plate 8 is provided at the bottom of the screw rod 2. A hexagonal nut 3 is provided on the outer side of the screw rod 2. The two ends of the first outer shell 101 and the second outer shell 102 are respectively installed through the first connection cover 6 and the second connection cover 7. This split type facilitates the assembly, disassembly, and carrying of the sand sampler, significantly improving the convenience of use. At the same time, by applying a rotational force to the hexagonal nut 3 with an external tool, the screw rod 2 can be rotated. During this process, through the threaded connection between the screw rod 2 and the connection block 5, the longitudinal position movement of the limiting plate 8 can be effectively promoted, enabling the sand sampler to adapt to different environments and meet various sampling standards. Specifically, by flexibly adjusting the longitudinal position of the limiting plate 8, the size of the geotechnical sampling area formed between it and the first outer shell 101 and the second outer shell 102 can be changed. In this way, the operator can precisely control the sampling amount of the geotechnical material, thereby greatly enhancing the functional practicality of the sand sampler and its applicability to different environments.

[0031] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 . A connecting rod 4 is provided at the top of the hexagonal nut 3 for connecting to an external impact tool. The setting of the connecting rod 4 enables the hexagonal nut 3 to be conveniently connected to the external impact tool, simplifies the sampling operation process, and improves work efficiency. At the same time, by applying force to the connecting rod 4 with an external impact tool, the hexagonal nut 3 can be rotated more effectively, thereby controlling the movement of the screw rod 2 and the limiting plate 8. This not only enhances the convenience of operation but also ensures the accuracy and controllability of the sampling process, enabling the geotechnical exploration sand sampler to efficiently and accurately complete the sampling task in various environments.

[0032] Refer to Figure 1, Figure 2 , Figure 3 , the cross-sections of the first outer shell 101 and the second outer shell 102 are both semi-circular structures. The semi-circular structures enable the first outer shell 101 and the second outer shell 102 to be easily closed and separated, simplifying the assembly and disassembly process of the sand sampler, improving the operational convenience. At the same time, the semi-circular structures also help to enhance the structural stability and load-bearing capacity of the sand sampler. When the two outer shells are closed, they can form a complete circular structure, thus better resisting external pressure and impact, protecting the internal geotechnical samples from damage, ensuring the integrity and quality of the geotechnical samples during the sampling process, and providing an accurate data basis for subsequent geotechnical exploration and analysis.

[0033] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , a connecting block 5 is provided at the top of the first connecting cover 6. The connecting block 5 is threadedly connected to the screw rod 2, ensuring a firm connection between the screw rod 2 and the connecting block 5. The threaded connection method has good self-locking properties, which can effectively prevent the screw rod 2 from loosening or falling off during operation, thereby improving the safety and reliability of the equipment. At the same time, the threaded connection also facilitates the adjustment and maintenance of the screw rod 2. When it is necessary to adjust the position of the limit plate 8 or replace damaged components, simply rotating the screw rod 2 can achieve connection and separation, simplifying the maintenance process, improving work efficiency, making the geotechnical exploration sand sampler more flexible and easy to use, and adapting to different working environments and operation requirements.

[0034] Refer to Figure 3 , Figure 4 , the bottom of the screw rod 2 is threadedly connected with a mounting block 10. The limit plate 8 is detachably structured with the screw rod 2 through the mounting block 10. Through the threaded connection, the mounting block 10 can be conveniently connected to the screw rod 2, making the installation and disassembly of the limit plate 8 simple and fast. At the same time, the detachable structure facilitates the replacement or maintenance of the limit plate 8, extending the service life of the equipment. If the limit plate 8 is damaged or needs to be replaced, simply disassembling the mounting block 10 can easily complete the replacement without major overhaul of the entire equipment, reducing the maintenance cost and time. Embodiment 2:

[0035] Refer to Figure 3 , Figure 4The limit plate 8 is rotatably connected to the mounting block 10 through the thrust bearing 9. This connection method allows the limit plate 8 to rotate freely on the mounting block 10, thereby reducing friction and resistance, making the screw 2 smoother when adjusting the position of the limit plate 8, and improving operating efficiency. At the same time, the use of the thrust bearing 9 enhances the stability and durability of the equipment. It can withstand large axial and radial loads, effectively preventing the limit plate 8 from deflecting and shaking during rotation, ensuring the accuracy and reliability of the sampling process, extending the service life of the equipment, reducing the maintenance frequency, and providing strong support for geotechnical exploration work.

[0036] See also Figure 3 , Figure 4 The limiting plate 8 is a disc-shaped structure, and the limiting plate 8 contacts the inner walls of the first shell 101 and the second shell 102. The disc-shaped structure enables the limiting plate 8 to fit better with the inner wall of the shell, effectively preventing the rock and soil samples from leaking from the side during the sampling process, ensuring the accuracy and integrity of the sampling. At the same time, the limiting plate 8 can effectively scrape off the residual rock and soil on the inner wall of the shell during the movement, keeping the sampling area clean, and providing convenience for subsequent sampling. In addition, the limiting plate 8 with a disc-shaped structure also has good structural stability and bearing capacity, can withstand greater rock and soil pressure, and ensure the smooth progress of the sampling process.

[0037] The implementation principle of the utility model is as follows: when the geotechnical exploration sand collector is needed, the first connecting cover 6 and the second connecting cover 7 are firstly used to install the two ends of the first shell 101 and the second shell 102, and then a tool is used to apply a rotational force to the hexagonal nut 3, so that the screw rod 2 is rotated, and at the same time, the threaded connection between the screw rod 2 and the connecting block 5 is used to promote the longitudinal position movement of the limit plate 8, and the cavity formed by the lower part of the limit plate 8 and the first shell 101 and the second shell 102 is the geotechnical sampling area, and the geotechnical sampling amount can be adjusted by changing the longitudinal position of the limit plate 8, so as to improve the environmental applicability of the sand collector to different environments and different sampling standards, and enhance its functional practicality;

[0038] The longitudinal movement of the limiting plate 8 is helpful to scrape off the rock and soil remaining on the inner walls of the first shell 101 and the second shell 102 , so as to facilitate the subsequent reuse of the sand extractor, further improving the functional diversity of the limiting plate 8 .
