[0002] Soil sampling equipment used in geological exploration is primarily used to collect soil samples for analysis of geological structure and soil properties. Common equipment includes soil samplers and drilling rigs. These devices allow soil samples to be obtained at different depths, helping geological engineers understand groundwater levels, soil types, and their bearing capacity. This information is crucial for projects such as construction, environmental assessments, and resource development, contributing to the development of scientifically sound engineering plans.
[0003] In existing technologies, the fixed length of the soil sampling structure in some soil sampling devices used for geological exploration leads to a limitation on the soil sampling distance, affecting the depth and range of the samples. This limitation makes it impossible to obtain soil samples from specific underground layers, thereby affecting the comprehensiveness and accuracy of geological analysis and causing the loss of important geological information, such as groundwater level or characteristics of different soil layers. Therefore, a soil sampling device for geological exploration is proposed to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0034] Reference Figure 2 , Figure 3 and Figure 5 This utility model provides an embodiment of a soil sampling device for geological exploration, comprising a pipe body 1. A fixing ring 6 is fixedly connected to the outside of the pipe body 1, providing support and fixing the position of the pipe body 1 relative to the fixing ring 6. A push handle 7 is rotatably connected inside the fixing ring 6, fixing the position of the push handle 7 relative to the fixing ring 6. A rotating column 8 is fixedly connected to the other end of the push handle 7, and the position change of the push handle 7 causes the rotating column 8 to rotate. A soil sampling shovel 5 is slidably connected to the inner wall of the pipe body 1, fixing the sliding position of the soil sampling shovel 5 relative to the pipe body 1.
[0035] The soil-removing shovel 5 has a groove 18 on its outside. The rotating column 8 is externally coupled to the inner wall of the groove 18. Under the action of the push handle 7, the rotating column 8 will squeeze the groove 18 (as shown in the attached figure). Figure 5 (The middle part is just squeezed). The outer sliding connection of the tube body 1 is a locking ring 11, which fixes the sliding position of the tube body 1 relative to the locking ring 11. The outer rotating connection of the fixed ring 6 is a reinforcing component used to reinforce the position of a certain length, and the fixed ring 6 fixes the position of the reinforcing component.
[0036] Reference Figure 1 , Figure 4 and Figure 5 The reinforcing assembly includes multiple push blocks 9, which are rotatably connected to the outside of a fixing ring 6. The fixing ring 6 supports and fixes the rotational position of the push blocks 9. Each push block 9 is rotatably connected to a locking rod 10; changes in the position of the push blocks 9 cause changes in the position of the locking rods 10. The locking rods 10 are slidably connected to the inner wall of the fixing ring 6 (as shown in the attached figure). Figure 5 The fixing ring 6 serves to fix the sliding position of the multiple locking rods 10. The external sliding connection of the multiple locking rods 10 is to the inner wall of the soil-removing shovel 5, and the multiple locking rods 10 have a secondary fixing effect on the position of the soil-removing shovel 5. The inner wall of the locking ring 11 is coupled to the outside of the fixing ring 6. After the positional relationship between the soil-removing shovel 5 and the pipe body 1 is determined, the locking ring 11 is close to the outside of the fixing ring 6, which can fix the position of the push block 9 outside the fixing ring 6, thereby strengthening the fastening.
[0037] Reference Figures 6 to 7 A handle 2 is fixedly connected to the outside of the pipe body 1, providing support and fixing the position of the handle 2. A plastic sleeve 17 is slidably connected to the outside of the handle 2, making it easier for operators to use. A bulldozer plate 12 is slidably connected to the inner wall of the shovel 5, fixing the sliding position of the bulldozer plate 12. A push rod 3 is fixedly connected to the outside of the bulldozer plate 12, and the position change of the push rod 3 causes the position change of the bulldozer plate 12. A handle 4 is fixedly connected to the other end of the push rod 3, providing support and fixing the position of the handle 4. Pushing the handle 4 moves the push rod 3. A cleaning plate 13 (as shown in the attached image) is slidably connected to the outside of the push rod 3. Figure 7 The push rod 3 serves to fix the sliding space of the cleaning plate 13.
[0038] The cleaning plate 13 is externally fixedly connected to multiple fixed posts 14, which support and fix its position. Each of the fixed posts 14 has a sliding post 15 internally connected, which fixes the sliding position of the fixed posts 14. The other end of each sliding post 15 is fixedly connected to the outside of the bulldozer blade 12; changes in the position of the bulldozer blade 12 cause changes in the position of the sliding posts 15. Springs 16 are fixedly connected to the inner walls of each fixed post 14, supporting and fixing their position. The other end of each spring 16 is fixedly connected to the inner wall of each sliding post 15, which supports and fixes the other end of the spring 16.
[0039] Working principle: Sliding the locking ring 11 and moving the push handle 7 causes the rotating column 8 to rotate slightly, allowing it to disengage from the surface of the soil-removing shovel 5. Moving multiple push blocks 9 causes their surfaces to move away from the soil-removing shovel 5. This positional change of the push blocks 9 causes multiple locking rods 10 to disengage from the soil-removing shovel 5, allowing it to slide freely on the inner wall of the pipe body 1. After determining the positional relationship between the soil-removing shovel 5 and the pipe body 1, moving the multiple push blocks 9 in the opposite direction pushes the locking rods 10 into the slots inside the soil-removing shovel 5, thus determining its position. Simultaneously, moving the push handle 7 in the opposite direction causes the rotating column 8 to move closer to the soil-removing shovel 5. The groove 18 on the surface of the soil shovel 5 allows the rotating column 8 to press against the groove 18, thereby reinforcing the positional relationship between the soil shovel 5 and the pipe body 1. Finally, the sliding locking ring 11 moves the inner wall of the locking ring 11 close to the outer wall of the fixing ring 6. The inner wall of the locking ring 11 is made of elastic material, which can lock the positions of multiple push blocks 9 to prevent the push blocks 9 from moving in the opposite direction and canceling the engagement. At the same time, it protects the outer wall of the fixing ring 6. The soil sampling depth can be flexibly selected according to the specific exploration depth and geological conditions to ensure the acquisition of soil samples from different layers, thereby improving the accuracy and comprehensiveness of geological analysis. The telescopic design facilitates transportation and storage, enhancing the portability and practicality of the equipment.
[0040] Rotating handle 4 moves push rod 3 closer to the sample soil. The position change of push rod 3 causes push plate 12 to move, pushing the sample soil out gradually. The position change of push plate 12 causes sliding column 15 to move, which in turn causes fixed column 14 to move. The position change of fixed column 14 causes cleaning plate 13 to remove sample soil that was not scraped off the side. If there is hard residue, cleaning plate 13 will remain. The retention of cleaning plate 13 will cause fixed column 14 to move away from push plate 12, thus deforming spring 16. The potential energy of spring 16 returning to its original position will cause fixed column 14 to move closer to push plate 12. The position change of fixed column 14 will cause cleaning plate 13 to continue moving forward, continuously cleaning stubborn residue. The soil sampling device cleans the inner wall while taking away the sample soil, which can effectively prevent sample contamination and ensure the accuracy of subsequent analysis. Cleaning the inner wall can also avoid the influence of residue on the next soil sampling. Keeping the inner wall clean helps to better observe and record the geological features during the soil sampling process.
[0041] 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.
