Description

Technical Field

[0001] This utility model relates to the field of civil engineering sampling technology, and in particular to a soil sampling device for geotechnical testing. Background Technology

[0002] In the field of geotechnical engineering, geotechnical testing is a key means of obtaining the physical and mechanical properties of soil, and the accuracy of the data directly affects the safety of engineering design and construction. High-quality undisturbed soil samples are the foundation for ensuring reliable test results, which places stringent requirements on the performance of soil sampling equipment.

[0003] Currently, traditional soil sampling devices for geotechnical testing have many limitations in practical applications. In the soil sample fixing stage, manual knobs or simple clip structures are often used, which is not only time-consuming but also difficult to precisely control the clamping force. This can easily lead to insufficient clamping force causing soil sample movement, or excessive clamping force damaging the soil sample structure. During the soil sample removal process, manual tapping or lever prying is often relied upon. This method is not only inefficient but can also cause irreversible disturbance to the soil sample, seriously affecting the accuracy of test data. Furthermore, traditional devices have low structural integration and poor inter-component coordination, failing to meet the requirements for rapid and stable soil sample collection under complex working conditions.

[0004] Traditional snap-fit ​​sampling devices result in significant compression deformation of soft soil samples, distorting key indicators such as void ratio and water content. Furthermore, relying on manual tapping or lever-operated methods during sample extraction is not only labor-intensive and inefficient, but also causes particle misalignment and stratification due to instantaneous impact, severely interfering with test results. Therefore, a soil sampling device for geotechnical testing is proposed to address these issues. Utility Model Content

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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a soil sampling device for geotechnical testing, including a supporting shell 1, which serves as the basic frame of the entire sampling device, providing structural support and protection for internal components, withstanding external force impacts and pressures during the sampling process, and ensuring the stability and safety of the device. A connecting fixing ring 5 is fixedly connected to the outside of the supporting shell 1, and a connecting fixing column 4 is fixedly connected inside the connecting fixing ring 5. The connecting fixing ring 5 and the connecting fixing column 4 constitute a device. A connecting mechanism 2 is fixedly connected inside the connecting fixing column 4, and a pushing mechanism 3 is slidably connected to the outside of the connecting mechanism 2. The connecting mechanism 2 includes a driving component 21 for driving. The driving component 21 serves as the power source of the connecting mechanism 2. Through the telescopic movement of the telescopic cylinder 211, it provides power for the clamping and releasing of the connecting clamping block 26, thereby realizing the rapid fixing and releasing of the sampling column 36.

[0033] The drive assembly 21 is externally fixedly connected to a connecting sliding block 22. The two sides of the connecting sliding block 22 are fixedly connected to a connecting rotating column 23. The two ends of the connecting rotating column 23 are rotatably connected to a connecting rotating rod 24. The linear motion of the drive assembly 21 is converted into the rotational motion of the connecting clamping block 26, thereby clamping the sampling column 36. The inner end of the connecting rotating rod 24, away from the connecting rotating column 23, is rotatably connected to a connecting rotating column 25. The outer side of the connecting rotating column 25 is rotatably connected to a connecting clamping block 26. The outer side of the connecting clamping block 26 is fixedly connected to a connecting clamping ring 27, thereby clamping and fixing the sampling column 36, ensuring the stability and integrity of the soil sample during the sampling process, and preventing the sampling column 36 from shaking or shifting and affecting the sampling effect.

[0034] The drive assembly 21 includes a telescopic cylinder 211. The drive end of the telescopic cylinder 211 is fixedly connected to a connecting telescopic rod 212. The outer end of the connecting telescopic rod 212, i.e., the end away from the telescopic cylinder 211, is fixedly connected to the inside of the connecting sliding block 22. The outer end of the connecting clamping ring 27 is slidably connected to the outside of the supporting housing 1. The outer end of the connecting rotating rod 24 is rotatably connected to the outside of the supporting housing 1. The outer end of the connecting sliding block 22 is slidably connected to the outside of the supporting housing 1. The outer end of the connecting rotating column 1 23 is slidably connected to the outside of the supporting housing 1. The outer end of the connecting telescopic rod 212 is slidably connected to the outside of the supporting housing 1. The outer end of the telescopic cylinder 211 is fixedly connected to the inside of the connecting fixing column 2 4. The outer end of the connecting telescopic rod 212 is slidably connected to the outside of the connecting fixing ring 5.

[0035] Reference Figure 1 , Figure 4 The ejection mechanism 3 includes a rotary motor 31. A connecting rotary column 32 is fixedly connected to the drive end of the rotary motor 31. A connecting rotary column 4 33 is fixedly connected to the outer end of the connecting rotary column 32, i.e., the end furthest from the rotary motor 31. The rotary motor 31 serves as the power source for the ejection mechanism 3, transmitting its rotational power to the ejection column 35 via the connecting rotary columns 32 and 4 33, thus achieving smooth ejection of the soil sample. A connecting fixed column 34 is slidably connected inside the connecting rotary column 4 33.

[0036] The external fixed connection of the connecting fixed column 34 is connected to the connecting ejection column 35, which converts the rotational motion of the connecting rotating column 33 into a linear ejection motion, smoothly ejecting the soil sample from the sampling column 36, facilitating subsequent soil sample analysis and testing. The external rotatable connection of the ejection column 35 is connected to the internal side of the connecting rotating column 33. The external rotatable connection of the connecting rotating column 33 is connected to the sampling column 36, which is used to collect and store soil samples. Its structural design must ensure the original state and integrity of the soil sample, and at the same time cooperate with the connecting mechanism 2 and the ejection mechanism 3 to realize the fixation and ejection of the soil sample. The internal rotatable connection of the sampling column 36 is connected to the external side of the connecting fixed column 34, the external rotatable connection of the connecting rotating column 33 is connected to the internal side of the sampling column 36, the external rotatable connection of the ejection column 35 is connected to the internal side of the sampling column 36, and the external sliding connection of the sampling column 36 is connected to the internal side of the connecting clamping ring 27.

[0037] Working principle: When it is necessary to quickly fix the sampling column 36, the operation of the telescopic cylinder 211 drives the sliding of the connecting telescopic rod 212, which in turn drives the telescopic sliding of the connecting sliding block 22 and the first connecting rotating column 23, thereby driving the rotation of the connecting rotating rod 24, which in turn drives the rotation of the connecting clamping block 26. At the same time, the second connecting rotating column 25 provides support for the rotation of the connecting clamping block 26, thus ensuring the normal operation of the connecting clamping block 26.

[0038] When it is necessary to remove the soil sample from inside the sampling column 36, the operation of the rotating motor 31 drives the rotation of the connecting rotating column 32, which in turn drives the rotation of the connecting rotating column 33, thereby driving the connecting fixed column 34 and the connecting push-out column 35 to rotate outward, thus achieving the effect of pushing out the soil sample.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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 make equivalent substitutions for some of the technical features. 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.
