Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically a shallow soil sampling device for geological exploration. Background Technology

[0002] Geological exploration is an investigation and research activity that uses various means and methods to explore and detect geology, determine suitable bearing strata, determine the foundation type based on the bearing capacity of the bearing strata, and calculate foundation parameters.

[0003] However, given the current state of geological exploration, the shallow manual soil sampling devices used in this field have some significant drawbacks. In actual exploration operations, after obtaining soil samples using such devices, tools such as digging tools need to be inserted into the sampling tube to separate the sample. However, this process of separating the soil sample from the tube can easily damage it. Once the soil sample is damaged, subsequent measurements will inevitably lack accuracy, thus affecting the accurate assessment of the geological conditions and soil composition throughout the geological exploration work. Utility Model Content

[0004] The purpose of this invention is to provide a shallow soil sampling device for geological exploration, which aims to solve the problem in the prior art that soil samples are easily damaged when they are peeled from the cylinder, resulting in inaccurate measurement results.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: the shallow soil sampling device for geological exploration includes a soil sampling component capable of sampling soil.

[0006] The soil sampler assembly includes an engine, a shaft that is drivenly connected to the engine output shaft and extends in the vertical direction, and a soil sampler cylinder that is detachably connected to the shaft.

[0007] The soil sampling cylinder includes several sets of plug-in plates and several sets of slotted plates. The plug-in plates and slotted plates are alternately connected and arranged, and both the plug-in plates and slotted plates are arc plates. The plug-in plates and slotted plates are assembled together to form a cylindrical structure that can be detachably connected to the shaft.

[0008] The slotted plate has a cavity, and a limiting component is provided in the cavity. The plug-in plate has a limiting groove adapted to the limiting component. When the limiting component and the limiting groove are adapted, the upper surfaces of the plug-in plate and the slotted plate remain flush.

[0009] The top of the slotted plate has a sliding hole communicating with the cavity. The limiting component is fixedly provided with a pulling member through the sliding hole. The pulling member moves along the sliding hole to move the limiting component along the extension direction of the cavity, so that the limiting component is disengaged from the limiting groove.

[0010] Preferably, arc-shaped short rods are fixedly provided on both sides of the plug-in plate, and a vertical rod extending in the vertical direction is fixedly provided at the end of the arc-shaped short rod away from the plug-in plate.

[0011] Preferably, both sides of the slotted plate are provided with arc-shaped short grooves, and the bottom of the arc-shaped short groove is provided with a vertical groove that opens in the direction of vertical movement. When the arc-shaped short rod is placed on the arc-shaped short groove, the vertical rod can be inserted into the vertical groove.

[0012] Preferably, both the plug-in plate and the slotted plate have through holes on their inner sides, and the through holes on the two plug-in plates correspond to each other, as do the through holes on the two slotted plates.

[0013] The end of the shaft away from the engine is threadedly connected to a connecting block, and the connecting block has a through round hole;

[0014] When the connecting block is inserted into the cylindrical structure, the round hole on the connecting block corresponds to the through hole, so that the pin passes through the through hole and the round hole to connect the cylindrical structure to the connecting block.

[0015] Preferably, the limiting component includes a telescopic cylinder assembly fixed in the cavity and extending laterally, a movable plate fixedly connected to the other end of the telescopic cylinder assembly, and an insert rod fixedly connected to the side of the movable plate away from the telescopic cylinder assembly.

[0016] The cavity has a through hole for the insertion rod to pass through, and the insertion rod passes through the through hole and is adapted to the limiting groove.

[0017] Preferably, the insertion rod extends out of the limiting groove and is fixedly connected to the pulling member.

[0018] Preferably, the telescopic cylinder assembly includes multiple telescopic sleeves and springs;

[0019] One end of the multi-section telescopic sleeve is fixedly connected to the inner wall of the cavity, and the other end of the multi-section telescopic sleeve is fixedly connected to the movable plate.

[0020] The spring is located inside the multi-section telescopic sleeve.

[0021] Preferably, both the insertion rod and the limiting groove are arc-shaped structures.

[0022] Preferably, the bottom of both the plug-in plate and the slotted plate are fixedly provided with spiral teeth.

[0023] The beneficial effects are: 1. After the soil sampler successfully completes the soil sampling, the cylindrical structure can be removed from the connecting block. Then, by moving the pulling element, the movement of the pulling element will cause the insertion rod to disengage from the limiting groove. Based on this, the insertion plate can be removed from the slotted plate. The purpose is to ensure that the soil sample remains in a more complete state. A complete soil sample plays a crucial role in improving measurement accuracy because it can more accurately reflect the various characteristics of the soil, thus providing more reliable data for measurement work and effectively improving measurement accuracy.

[0024] 2. In practice, the interplay between the vertical rod and the vertical slot plays a crucial role. The precise embedding of the vertical rod into the vertical slot, much like a mortise and tenon joint, provides accurate positioning and a reliable connection for the assembly of the insert plate and the slotted plate. This connection method ensures the entire structure maintains good stability even under various external forces. For cylindrical structures, any misalignment may prevent the soil sampling tool from accurately reaching the intended position, affecting the quality and efficiency of soil sampling. By ensuring the stability of the fit and assembly of the insert plate and the slotted plate through the vertical rod and vertical slot, such problems can be prevented at the source, thus ensuring efficient and accurate soil sampling.

[0025] 3. By setting the limiting component, after the plug plate is inserted into the slotted plate, the plug rod can be inserted into the limiting groove, so that the adjacent plug plate and the slotted plate are locked together, so as to ensure that the upper surface of the plug plate and the slotted plate are flush, and to avoid misalignment of the plug plate and the slotted plate, which would result in poor soil sampling results.

[0032] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0033] like Figures 1-5 As shown, a shallow soil sampling device for geological exploration is mainly used to facilitate the collection of soil samples after the soil sampling device assembly has completed soil sampling, so as to improve the accuracy of detection.

[0034] In this embodiment, the soil sampling device includes a soil sampler assembly capable of sampling soil. The soil sampler assembly includes an engine 1, a shaft 2 that is driven to the output shaft of the engine 1 and extends in the vertical direction, and a soil sampling cylinder 3 that is detachably connected to the shaft 2. After the engine 1 is started, it can drive the shaft 2 to rotate. When the shaft 2 rotates, it can drive the soil sampling cylinder 3 to rotate so that it can be screwed into the soil for sampling.

[0035] In this embodiment, the structure and principle of the soil sampler assembly are existing technologies and will not be described in detail here.

[0036] like Figures 1-3 As shown, the soil sampling tube 3 includes several sets of plug-in plates 301 and several sets of slotted plates 302. The plug-in plates 301 and slotted plates 302 are alternately connected and arranged, and both the plug-in plates 301 and the slotted plates 302 are arc plates.

[0037] Specifically, curved short rods are fixed on both sides of the plug-in plate 301, and a vertical rod 8 extending in the vertical direction is fixed at the end of the curved short rod away from the plug-in plate 301. Curved short grooves are formed on both sides of the slotted plate 302, and a vertical groove 9 with an opening facing upwards and extending in the vertical direction is formed at the bottom of the curved short groove. When the curved short rod is placed on the curved short groove, the vertical rod 8 can be inserted into the vertical groove 9. When the vertical rod 8 is embedded in the vertical groove 9, the curved short rod is embedded in the curved short groove, just like a mortise and tenon joint, providing precise positioning and reliable connection for the combination of the plug-in plate 301 and the slotted plate 302.

[0038] like Figure 2As shown, both the inner sides of the plug-in plate 301 and the slotted plate 302 are provided with through holes 11, and the through holes 11 on the two plug-in plates 301 correspond to each other, and the through holes 11 on the two slotted plates 302 correspond to each other; the end of the shaft 2 away from the engine 1 is threadedly connected to a connecting block 10. In this embodiment, the structure and principle of the engine 1 are existing technologies and will not be described in detail here. The connecting block 10 is provided with a through round hole; when the plug-in plate 301 and the slotted plate 302 are fitted and assembled, a cylindrical structure is formed. Then the connecting block 10 is inserted into the cylindrical structure, and the round hole on the connecting block 10 corresponds to the through hole 11. Then, a pin passes through the through hole 11 and the round hole to connect the cylindrical structure to the connecting block 10, so that when the shaft 2 rotates, it can drive the connecting block 10 to rotate, and when the connecting block 10 rotates, it can drive the cylindrical structure to rotate.

[0039] like Figures 1-3 As shown, the bottom of both the plug plate 301 and the slotted plate 302 are fixedly provided with spiral teeth 12. When the cylindrical structure rotates, it can be screwed into the soil through the spiral teeth 12 to take samples.

[0040] like Figure 3 and Figure 4 As shown, when the plug plate 301 is inserted into the slotted plate 302, the limiting component 5 can lock the plug plate 301 into the slotted plate 302 together, so as to prevent the plug plate 301 from being misaligned when inserted into the slotted plate 302.

[0041] Specifically, the slotted plate 302 has a cavity 4 inside, and a limiting component 5 is provided inside the cavity 4. The plug-in plate 301 has a limiting groove 6 that is adapted to the limiting component 5. When the plug-in plate 301 is inserted into the slotted plate 302, the limiting component 5 is adapted to the limiting groove 6, so that the upper surfaces of the plug-in plate 301 and the slotted plate 302 remain flush.

[0042] The limiting component 5 includes a telescopic cylinder assembly 501 fixed in the cavity 4 and extending laterally, a movable plate 502 fixedly connected to the other end of the telescopic cylinder assembly 501, and an insertion rod 503 fixedly connected to the side of the movable plate 502 away from the telescopic cylinder assembly 501. A through hole is provided in the cavity 4 for the insertion rod 503 to pass through. When the insertion plate 301 is inserted into the slotted plate 302, the insertion rod 503 on the insertion plate 301 will pass through the through hole and be inserted into the limiting groove 6 under the action of the telescopic cylinder assembly 501, so as to lock the insertion plate 301 and the slotted plate 302.

[0043] In this embodiment, the perforation can limit and guide the sliding of the insertion rod 503, preventing the insertion rod 503 from deviating. When the insertion rod 503 is retracted, it is located inside the perforation so that it can be used again next time.

[0044] The telescopic cylinder assembly 501 includes multiple telescopic sleeves and a spring. In this embodiment, the multiple telescopic sleeves are composed of multiple arc-shaped sleeves assembled together, and the spring is also an arc-shaped spring. The structure and principle of the arc-shaped sleeves and the arc-shaped spring are existing technologies and will not be described in detail here. One end of the multiple telescopic sleeves is fixedly connected to the inner wall of the cavity 4, and the other end of the multiple telescopic sleeves is fixedly connected to the moving plate 502. The spring is located inside the multiple telescopic sleeves. Without external force, the telescopic cylinder assembly 501 can push the insertion rod 503 into the limiting groove 6. Both the insertion rod 503 and the limiting groove 6 are arc-shaped structures.

[0045] like Figure 4 As shown, a sliding hole communicating with the cavity 4 is opened on the top of the slotted plate 302. The limiting component 5 is fixedly provided with a pulling member 7 through the sliding hole. The insert rod 503 passes through the limiting groove 6 and is fixedly connected to the pulling member 7. When it is necessary to remove the insert plate 301 and the slotted plate 302, the pulling member 7 moves along the sliding hole to move the limiting component 5 along the extension direction of the cavity 4, so that the limiting component 5 is disengaged from the limiting groove 6.

[0046] Working principle: Before use, connect engine 1 to shaft 2, and connect shaft 2 to connecting block 10. Then, insert the vertical rod 8 on the plug plate 301 into the vertical slot 9 on the slotted plate 302. At this time, the cylindrical structure formed by the fitting and assembly of plug plate 301 and slotted plate 302 is flush. Then, the plug rod 503 is pushed into the limiting slot 6 under the action of telescopic cylinder assembly 501 to lock plug plate 301 and slotted plate 302. After that, the connecting block 10 is inserted. The cylindrical structure is formed by the mutual fitting and assembly of the insert plate 301 and the slotted plate 302, and the round hole on the connecting block 10 corresponds to the through hole 11. Then, the pin passes through the through hole 11 and the round hole to connect the cylindrical structure to the connecting block 10. When the shaft 2 rotates, it can drive the connecting block 10 to rotate. When the connecting block 10 rotates, it can drive the cylindrical structure to rotate. When the cylindrical structure rotates, it can be screwed into the soil through the spiral teeth 12 for sampling.

[0047] After sampling is completed, the pin can be removed. At this time, the cylindrical structure is separated from the connecting block 10. Then, the puller 7 is moved along the sliding hole to move the limiting component 5 along the extension direction of the cavity 4, so that the limiting component 5 is separated from the limiting groove 6. At this time, the plug plate 301 can be removed from the slotted plate 302. Then the soil sample can be taken off for testing to improve the integrity of the soil sample and thus improve the accuracy of the inspection.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
