Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, and in particular to an automatic soil sampling device and control method for geological exploration. Background Technology

[0002] Geological exploration refers to the investigation and analysis of geological structures, mineral distribution, and soil and rock properties in the Earth's surface and deep layers using various technical means. It is a crucial foundational work for resource development, engineering construction, and environmental assessment. In this process, soil sample collection and analysis is a key step in obtaining subsurface information; the quality and efficiency of sampling directly affect the accuracy of subsequent data interpretation and the scientific basis of engineering decisions. Especially in complex terrain or large-scale exploration missions, traditional manual sampling methods are not only labor-intensive and inefficient but also struggle to guarantee sample integrity and consistency. Therefore, developing automated sampling equipment for geological exploration has become an urgent need for the industry.

[0003] An existing soil sampling device for geological exploration (invention patent CN 221404767 U) discloses a structural design including a central plate, an insertion tube, and a soil sampler. The soil sampler consists of two semi-circular tubes, secured by end caps, and equipped with a step-on outer ring and a pull rope structure for easy single-person operation. While this device achieves advantages such as compact size, portability, and ease of operation, and the extracted soil sample maintains a complete soil column shape and is not easily broken, it still has shortcomings: The device cannot automatically adjust the sampling depth and sampling volume according to different geological conditions (such as soft soil, gravel layer or hard soil layer), which leads to frequent equipment replacement or manual parameter adjustment in practical applications, seriously affecting sampling efficiency.

[0004] Therefore, in response to the shortcomings of existing technologies, we urgently need an automatic soil sampling device and control method for geological exploration. This device should be able to intelligently adjust the sampling depth and sampling volume according to geological conditions, significantly improve sampling efficiency and the accuracy of sample structure, and at the same time have good automated control capabilities and multi-scenario adaptability, so as to better meet the needs of modern geological exploration work for high efficiency, precision and intelligence, and provide strong support for the sustainable development of related fields such as civil defense construction, mineral exploration, and environmental monitoring. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic soil sampling device and control method for geological exploration, which solves the problem that the sampling depth and sampling volume cannot be automatically adjusted according to different geological conditions, such as soft soil, gravel layer or hard soil layer, which leads to frequent equipment replacement or manual parameter adjustment in practical applications and seriously affects sampling efficiency.

[0006] To achieve the above objectives, the present invention provides an automatic soil sampling device for geological exploration, comprising an unmanned vehicle, two horizontally moving frames connected to the top of the unmanned vehicle, and a translation frame slidably connected to the top of the two horizontally moving frames. A moving plate is slidably connected to the top of the translation frame, and a lifting frame is connected to the top of the moving plate. The lifting frame has an internal mounting plate. The bottom of the mounting plate is connected to a sampling tube that slides through the moving plate at one end. The top of the mounting plate is connected to a connecting frame. The connecting frame is connected to the top of the lifting frame through a vertical lifting structure. The top of the mounting plate is provided with a pushing structure. The output end of the pushing structure is connected to a pushing column set inside the sampling tube. One side of the translation frame is equipped with a pushing structure one for pushing the moving plate, and one side of the two horizontal moving frames is equipped with a pushing structure two for pushing the translation frame. The unmanned vehicle has a processing and execution module installed on one side of its top, and sensor modules are installed at one end of the two horizontal moving frames. Several storage tubes are connected to the top of the unmanned vehicle.

[0007] The unmanned vehicle has several limiting cylinders connected to its top, and the storage tube is detachably connected to the inside of the limiting cylinders.

[0008] The vertical lifting structure includes a third push cylinder installed on the top of the lifting frame, and the output end of the third push cylinder is connected to the top of the connecting frame.

[0009] Each of the two horizontally movable frames has a support frame at its bottom, and the support frame is bolted to the top of the unmanned vehicle.

[0010] The first pushing structure includes a second pushing cylinder installed on one side of the translation frame, and the output end of the second pushing cylinder is connected to the side wall of the moving plate.

[0011] The second pushing structure includes two pushing cylinders connected to the side wall of the horizontal moving frame, and the output end of the pushing cylinder is connected to the translation frame.

[0012] An automatic soil sampling control method for geological exploration is applied to the automatic soil sampling equipment for geological exploration.

[0013] This invention discloses an automatic soil sampling device and control method for geological exploration. By incorporating a sensor module and a processing execution module, it achieves intelligent identification and response to different geological conditions. It can automatically adjust the sampling depth and volume based on real-time data, effectively solving the inefficiency problem caused by frequent manual adjustments in existing technologies. Secondly, it uses an unmanned vehicle as a mobile platform, combined with multi-degree-of-freedom moving mechanisms such as horizontal moving frames, translation frames, and lifting frames, giving the device excellent mobility and spatial adaptability. It can flexibly position itself in complex terrain, significantly improving the sampling coverage and operational efficiency. Thirdly, the sampling tube...

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Example 1 Please see Figure 1-5 As shown, an automatic soil sampling device for geological exploration in this embodiment includes an unmanned vehicle 4, two horizontally movable frames 3 connected to the top of the unmanned vehicle 4, and a translation frame 10 slidably connected to the top of the two horizontally movable frames 3. A movable plate 12 is slidably connected to the top of the translation frame 10, and a lifting frame 1 is connected to the top of the movable plate 12. The lifting frame 1 has an internal mounting plate 17. The bottom of the mounting plate 17 is connected to a sampling tube 2 that slides through the moving plate 12 at one end. The top of the mounting plate 17 is connected to a connecting frame 14. The connecting frame 14 is connected to the top of the lifting frame 1 through a vertical lifting structure. The top of the mounting plate 17 is provided with a pushing structure. The output end of the pushing structure is connected to a pushing column 16 located inside the sampling tube 2. A first pushing structure for pushing the movable plate 12 is installed on one side of the translation frame 10, and a second pushing structure for pushing the translation frame 10 is installed on one side of the two horizontal moving frames 3. The unmanned vehicle 4 has a processing and execution module 6 installed on one side of its top, and sensor modules 7 installed at one end of the two horizontal moving frames 3. Several storage tubes 5 are connected to the top of the unmanned vehicle 4.

[0023] First, the unmanned vehicle 4 travels to the target sampling area according to a preset route or remote control command. Then, the ground radar, camera, and pressure sensor in the sensor module 7 begin to scan and collect data on the current ground environment in real time, obtaining geological parameters such as soil hardness, density, and water content. This information is then transmitted to the processing and execution module 6, which analyzes and determines the optimal sampling location and depth. After the sampling point is determined, the second push structure is activated, causing the translation frame 10 to slide along the two horizontal moving frames 3 to the designated position. At the same time, the vertical lifting structure starts working, driving the mounting plate 17 and the sampling tube 2 connected to its bottom to move downwards and insert into the soil to complete the sampling action. After sampling is completed, the vertical lifting structure retracts, causing the sampling tube 2 to rise and detach from the ground. At this time, the second push structure is activated again, moving the translation frame 10 above the storage tube 5. Simultaneously, the first push structure is activated, pushing the moving plate 12 to move laterally, aligning the sampling tube 2 with the corresponding storage tube 5. Then, the pushing structure starts operating, driving the pushing column 16 forward to push the soil sample in the sampling tube 2 completely out and fall into the storage tube 5 to complete the collection. The entire process is coordinated by the processing and execution module 6, which enables automated continuous sampling and sample transfer without manual intervention. It is suitable for complex terrain exploration tasks involving multiple locations and large areas.

[0024] Example 2 Please see Figure 1-5 As shown in this embodiment, an automatic soil sampling device and control method for geological exploration is provided. The top of the unmanned vehicle 4 is connected to several limiting cylinders, and the storage tube 5 is detachably connected to the inside of the limiting cylinders. Specifically, through the setting of several limiting cylinders connected to the top of the unmanned vehicle 4 and the storage tube 5 being detachably connected to the inside of the limiting cylinders, after sampling is completed, the pushing structure 1 and the vertical lifting structure work together to push the soil sample in the sampling tube 2 into the corresponding storage tube 5. Since the storage tube 5 is firmly fixed by the limiting cylinders, the problem of sample spillage or contamination caused by vibration or other external forces during sample transfer is avoided, thereby achieving the effect of improving the integrity and consistency of sample preservation.

[0025] Both horizontal moving frames 3 are connected to support frames 8 at their bottoms. The support frames 8 are bolted to the top of the unmanned vehicle 4. Specifically, by connecting the support frames 8 to the bottoms of both horizontal moving frames 3 and bolting them to the top of the unmanned vehicle 4, the basic stability of the entire equipment is enhanced. Especially when operating on uneven terrain, the support frames 8 can provide additional support, ensuring that the horizontal moving frames 3 and the moving frame 10 remain stable during movement. This avoids inaccurate positioning or sampling failure caused by equipment shaking, thus enhancing the stability and reliability of the equipment.

[0026] Example 3 Please see Figure 1-5As shown in this embodiment, an automatic soil sampling device and control method for geological exploration includes a vertical lifting structure comprising a push cylinder 13 mounted on the top of a lifting frame 1. The output end of the push cylinder 13 is connected to the top of a connecting frame 14. Specifically, by connecting the output end of the push cylinder 13 mounted on the top of the lifting frame 1 to the top of the connecting frame 14, after determining the optimal sampling position and depth, the processing execution module 6 controls the push cylinder 13 to start, driving the mounting plate 17 and sampling tube 2 to move precisely up and down, thereby realizing the collection and extraction of soil samples. Since the push cylinder 13 is used as the power source, the stability and accuracy of the sampling process are ensured, achieving the effect of improving sampling efficiency and quality.

[0027] The first pushing structure includes a second pushing cylinder 11 installed on one side of the translation frame 10. The output end of the second pushing cylinder 11 is connected to the side wall of the moving plate 12. Specifically, by installing the second pushing cylinder 11 on one side of the translation frame 10 and connecting its output end to the side wall of the moving plate 12, when it is necessary to adjust the position of the sampling tube 2 to align with the storage tube 5, the second pushing cylinder 11 precisely pushes the moving plate 12 according to the instructions of the processing execution module 6, so that the sampling tube 2 is accurately aligned with the target storage tube 5. This achieves efficient transfer of samples from the sampling tube to the storage tube, avoids errors and time waste caused by manual calibration, and achieves the purpose of simplifying the operation process and improving work efficiency.

[0028] The second pushing structure includes two pushing cylinders 9 connected to the side wall of the horizontal moving frame 3. The output end of the pushing cylinders 9 is connected to the translation frame 10. Specifically, through the setting of the two pushing cylinders 9 connected to the side wall of the horizontal moving frame 3 and their output ends connected to the translation frame 10, after the sampling point is determined, the pushing cylinders 9 precisely drive the translation frame 10 to slide along the horizontal moving frame 3 to the designated position according to the control signal of the processing execution module 6, so that the sampling tube 2 can accurately reach the predetermined sampling point for sampling. This design not only improves the spatial coverage and flexibility of the equipment, but also ensures the accuracy of multi-point sampling, and meets the needs of optimizing equipment layout and adapting to complex terrain sampling. The pushing structure includes a pushing cylinder 15, the output end of which is connected to a pushing column 16 to push the soil out of the sampling tube 2.

[0029] This solution includes the following work process: In the workflow of this automated soil sampling equipment for geological exploration, the unmanned vehicle 4 first travels to the target sampling area according to a preset route or remote control command. Upon arrival, the ground radar, camera, and pressure sensor in the sensor module 7 begin to scan and collect data on the current ground environment in real time, obtaining geological parameters such as soil hardness, density, and water content, and transmitting this information to the processing and execution module 6. The processing and execution module 6 analyzes and determines the optimal sampling location and depth. After determining the sampling point, the second push structure, namely two push cylinders 9 connected to the side wall of the horizontal moving frame 3, whose output ends are connected to the translation frame 10, precisely drives the translation frame 10 to slide along the horizontal moving frame 3 to the designated position according to the control signal of the processing and execution module 6. At the same time, the vertical lifting structure includes a third push cylinder 13 installed on the top of the lifting frame 1, whose output end is connected to the top of the connecting frame 14, driving the mounting plate 17 and the sampling tube 2 connected to its bottom to move downwards and insert into the soil to complete the sampling action. After sampling is completed, the vertical lifting structure retracts, causing the sampling tube 2 to rise and detach from the ground. At this time, the first push cylinder 9 actuates again, moving the translation frame 10 above the storage tube 5. Simultaneously, the first push structure is activated, namely the second push cylinder 11 installed on one side of the translation frame 10, whose output end is connected to the side wall of the moving plate 12, precisely pushing the moving plate 12 to align the sampling tube 2 with the corresponding storage tube 5. Subsequently, the pushing structure begins operation, namely the part set on the top of the mounting plate 17 and connected to the push column 16. The fourth push cylinder 15 drives the push column 16 forward, pushing the soil sample in the sampling tube 2 completely out and into the storage tube 5 to complete the collection.

[0030] Regarding the beneficial effects, the entire system utilizes several limiting cylinders connected to the top of the unmanned vehicle 4, allowing the storage tube 5 to be detachably connected inside the limiting cylinders. This securely fixes the storage tube 5 during sample transfer, preventing sample spillage or contamination caused by vibration or other external forces, thus improving the integrity and consistency of sample preservation. Furthermore, the use of cylinder three 13 as the power source for the vertical lifting structure ensures the stability and accuracy of the sampling process, improving sampling efficiency and quality. The bolted connection between the support frame 8 and the top of the unmanned vehicle 4 enhances the basic stability of the equipment, providing additional support, especially when operating on uneven terrain. This ensures the stability of the horizontal moving frame 3 and the translation frame 10 during movement, reducing the risk of inaccurate positioning or sampling failure due to equipment shaking. The use of cylinder two 11 and cylinder one 9 enables precise position adjustment, simplifying the operation process, improving work efficiency, and optimizing the equipment layout to adapt to the needs of sampling in complex terrain. This design not only improves spatial coverage and flexibility but also ensures the accuracy of multi-point sampling, providing an efficient, accurate, and intelligent solution for modern geological exploration.
