Description
Technical Field
[0001] This utility model relates to the field of geological exploration technology, and in particular to a soil sampler for geological exploration. Background Technology
[0002] A soil sampler is a specialized tool used to collect underground soil and rock samples. It is widely used in geological surveys and engineering explorations. Typical soil samplers include cylindrical samplers and hammer samplers. They are usually made of metal and can effectively sample at different soil layers and depths, preserving the natural structure, water content and other physical and mechanical properties of the soil samples. This provides a basis for accurate analysis and research on the engineering characteristics of foundation soil.
[0003] A search revealed Chinese patent publication number CN220018973U, which discloses a portable soil sampler for geological exploration. The sampler includes a support plate with a first threaded hole at its center. A connecting rod is threaded into the first threaded hole, and a handle is bolted to the upper end of the connecting rod. A soil sampling cylinder is detachably connected to the lower end of the connecting rod. Support legs are symmetrically and movably connected to the lower end of the support plate. This utility model has a reasonable structure and utilizes the detachable connections between its components to solve the problems of inconvenient installation and carrying, and limited application range, of conventional large-scale mechanical soil samplers. During the process, the entry and lifting movements of the soil sampler can easily disturb the soil sample, damaging its original structure and affecting the accuracy of its physical and mechanical properties. This is especially noticeable in sensitive strata such as soft soil. The static pressure method is a gentler sampling method that reduces disturbance to the soil sample. At the same time, a buffer device is installed inside the soil sampler to reduce the impact force on the soil sample during lifting. However, in low-temperature environments, the soil layer hardens, and the soil sampler will experience greater friction and resistance when entering the soil layer. A larger external force is required to press the soil sampler into the soil layer, increasing the difficulty of operation. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a soil sampler for geological exploration, which aims to improve the existing technology where, in low-temperature environments, the soil layer hardens, and the soil sampler is subjected to greater friction and resistance when entering the soil layer, requiring greater external force to press the soil sampler into the soil layer, thus increasing the difficulty of operation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a soil sampler for geological exploration, comprising a base, a housing fixedly connected to the top of the base, a motor mounted on the top of the housing, a gear one fixedly connected to the output end of the motor, the gear one rotatably connected to the front side of the inner wall of the housing, a gear two rotatably connected to the rear side of the inner wall of the housing, the gear one and gear two meshing, a rotating shaft fixedly connected to the bottom end of the gear two, a spiral disk fixedly connected to the outer wall of the rotating shaft, a drill bit fixedly connected to the end of the rotating shaft, an electrical wire mounted on the right side of the outer wall of the motor, a discharge hopper mounted on the lower rear side of the housing, and an installation mechanism mounted on the bottom of the base, the installation mechanism facilitating installation and disassembly and enabling cleaning of the internal structure.
[0006] Through the above technical solution: a rotating shaft is fixedly connected to the bottom end of gear two. The rotation of the motor drives gear one to rotate. A spiral disk is fixedly connected to the outer wall of the rotating shaft. Gear one and gear two are meshed and connected. The rotation of gear one drives gear two to rotate, which in turn drives the rotating shaft and spiral disk to rotate. The drill bit can improve the soil sampler's compressive strength and wear resistance, and also improve the drilling efficiency in hard strata. After the drill bit drills into the ground, the spiral disk continues to rotate to transport the collected soil upwards, so that the soil can be discharged from the discharge bin, making soil sampling convenient.
[0007] As a further description of the above technical solution:
[0008] The installation mechanism includes a clamping plate, which is fixedly installed at the bottom of the base. An arc-shaped plate is fixedly connected to the inner side of the clamping plate. A hinge is installed on the middle left side of the arc-shaped plate. A clamping plate is installed on the right side of the hinge. An arc-shaped plate is fixedly connected to the inner side of the clamping plate. Mounting blocks are fixedly connected to the right side of the outer walls of both the clamping plate and the clamping plate. Bolts are threaded at equal intervals on the inner side of the mounting blocks.
[0009] With the above technical solution: after the soil is removed, the second rotating bolt is taken out of the mounting block, and the mounting block is pried open so that the second clamp plate can rotate on the hinge, thereby opening the second clamp plate and the second arc plate to clean the internal rotating shaft and spiral disc. After cleaning, the second clamp plate is closed and the bolt is tightened to fix it. The operation is convenient and easy to disassemble and clean.
[0010] As a further description of the above technical solution:
[0011] A controller is installed at the end of the wire, and a display screen is installed on the left side of the outer wall of the controller.
[0012] Through the above technical solution, the controller can accurately control the depth of the soil sampler entering the soil layer, ensuring that soil samples are obtained at a specific depth to meet the exploration requirements. The display screen shows parameters such as soil sampling depth, speed, and pressure, as well as operation menus and prompts.
[0013] As a further description of the above technical solution:
[0014] Two hinges are installed on the left and right sides of the front side of the outer wall of the controller, and a door panel is fixedly connected to the rear side of each of the multiple hinges.
[0015] Through the above technical solution, the door panel can effectively prevent personnel from accidentally touching the live parts inside the controller, avoiding electric shock accidents. At the same time, it can also block dust, moisture, foreign objects and other contaminants from entering the controller, protecting the electrical equipment inside the controller from the influence of external environmental factors and ensuring the normal operation of the equipment.
[0016] As a further description of the above technical solution:
[0017] The door panel has handles fixedly connected to the left and right ends of the front side of the outer wall, and anti-slip sleeves are rotatably connected to the outer sides of the two handles.
[0018] Through the above technical solution: the handle is used to open and close the door panel of the controller, which facilitates the operation of equipment inspection and maintenance by the staff. The anti-slip sleeve has good elasticity and flexibility, and can fit tightly on the handle to provide a good anti-slip effect. At the same time, the anti-slip sleeve also has certain insulation properties and corrosion resistance, and can adapt to different working environments.
[0019] As a further description of the above technical solution:
[0020] The base has multiple support rods rotatably connected at equal intervals on its bottom wall, and limit blocks are fixedly connected to the upper and lower ends of the outer wall of each support rod.
[0021] Through the above technical solution, the support rod provides the necessary support force for the soil sampler, enabling it to maintain a stable posture. Especially when drilling into deeper soil layers, the support rod can withstand the weight of the soil sampler and various forces generated during the drilling process, preventing the soil sampler from tilting or shaking, and ensuring the accuracy and quality of soil sampling.
[0022] As a further description of the above technical solution:
[0023] The inner wall of the support rod is slidably connected to a support leg, and the end of the support leg is fixedly connected to a pointed end.
[0024] The above technical solution allows the pointed tip to make better contact with the support surface of the ground outriggers, thereby achieving stable support and precise leveling operations.
[0025] As a further description of the above technical solution:
[0026] A fixing plate is installed on the left side of the end of the support leg, and a threaded bolt is connected to the bottom wall of the fixing plate.
[0027] The above technical solution involves placing the pointed end on the ground, adjusting the angle of the fixing plate, and then rotating bolt one. When bolt one is rotated to the ground, it will drill into the ground and become difficult to remove, thus firmly fixing the outrigger to the ground and providing strong grip for the equipment.
[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, a rotating shaft is fixedly connected to the bottom end of gear two. The rotation of the motor drives gear one to rotate. A spiral disk is fixedly connected to the outer wall of the rotating shaft. Gear one and gear two are meshed and connected. The rotation of gear one drives gear two to rotate, which can drive the rotating shaft and spiral disk to rotate. The drill bit can improve the soil sampler's compressive strength and wear resistance, and also improve the drilling efficiency in hard strata. After the drill bit drills into the ground, the spiral disk continues to rotate to transport the collected soil upwards, so that the soil can be discharged from the discharge bin, making soil sampling convenient.
[0030] 2. In this utility model, after the soil is removed, the second rotating bolt is taken out of the mounting block. The mounting block is then turned so that the second clamping plate rotates on the hinge, which opens the second clamping plate and the second arc plate. The internal rotating shaft and spiral disc are then cleaned. After cleaning, the second clamping plate is closed and the bolt is tightened to fix it. The operation is convenient and easy to disassemble and clean. Attached Figure Description

[0038] 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.
[0039] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a soil sampler for geological exploration, comprising a base 1, a housing 3 fixedly connected to the top of the base 1, a motor 4 mounted on the top of the housing 3, a gear 20 fixedly connected to the output end of the motor 4, the gear 20 being rotatably connected to the front side of the inner wall of the housing 3, and a gear 21 rotatably connected to the rear side of the inner wall of the housing 3, with the gear 20 and gear 21 meshing together. A rotating shaft 23 is fixedly connected to the bottom end of the gear 21, a spiral disk 19 is fixedly connected to the outer wall of the rotating shaft 23, and a drill bit 22 is fixedly connected to the end of the rotating shaft 23. An electrical wire 5 is mounted on the right side of the outer wall of the motor 4, and a discharge hopper 18 is mounted on the lower rear side of the housing 3. The base of the gear 21 is fixedly connected to the rotating shaft 23. When the motor 4 starts rotating, it drives the gear 20 to rotate synchronously. The spiral disk 19 on the outer wall of the rotating shaft 23 interacts with the gear 20 through meshing. Therefore, when the gear 20 transmits power to the gear 21, it can effectively drive the rotating shaft 21. The 3 and spiral disk 19 rotate together. The introduction of drill bit 22 not only significantly enhances the compressive strength and wear resistance of the soil sampler, but also greatly improves the drilling efficiency in hard strata. After the drill bit 22 penetrates the strata, the spiral disk 19 continues to rotate, transporting the soil collected by the drill bit 22 upward, thereby ensuring that the soil can be smoothly discharged from the discharge bin 18, which significantly improves the convenience of soil sampling operations. The bottom of the base 1 is equipped with an installation mechanism 2, which is convenient for installation and disassembly and facilitates cleaning of the internal structure. The end of the wire 5 is equipped with a controller 6. The left side of the outer wall of the controller 6 is equipped with a display screen 7. The left and right sides of the front side of the outer wall of the controller 6 are equipped with two hinges 8. The rear sides of the multiple hinges 8 are fixedly connected with door panels 9. The door panels 9 can effectively prevent personnel from accidentally touching the live parts inside the controller 6, avoiding electric shock accidents. At the same time, it can also block dust, water vapor, foreign objects and other objects from entering the inside of the controller 6, protecting the electrical equipment inside the controller 6 from the influence of external environmental factors and ensuring the normal operation of the equipment.
[0040] Specifically, a rotating shaft 23 is fixedly connected to the bottom end of gear 21. The rotation of motor 4 drives gear 1 20 to rotate. A spiral disk 19 is fixedly connected to the outer wall of rotating shaft 23. Gear 1 20 meshes with gear 21. The rotation of gear 21 driven by gear 1 20 can drive rotating shaft 23 and spiral disk 19 to rotate. Drill bit 22 can improve the soil sampler's compressive and wear resistance, and also improve drilling efficiency in hard strata. After drill bit 22 drills into the ground, spiral disk 19 continues to rotate to transport the collected soil upwards, so that the soil can be discharged from discharge bin 18, making soil collection convenient.
[0041] Reference Figure 1 , Figure 2 and Figure 5The installation mechanism 2 includes a clamping plate 202, which is fixedly installed at the bottom of the base 1. An arc-shaped plate 201 is fixedly connected to the inner side of the clamping plate 202. A hinge 206 is installed on the middle left side of the arc-shaped plate 201, and a clamping plate 207 is installed on the right side of the hinge 206. An arc-shaped plate 205 is fixedly connected to the inner side of the clamping plate 207. Mounting blocks 203 are fixedly connected to the right side of the outer walls of both the clamping plate 202 and the clamping plate 207. Bolts 204 are threaded at equal intervals on the inner side of the mounting blocks 203. After the soil sampling operation is completed, the operator can rotate bolts 204 to remove the soil sampler from the mounting blocks 203. Subsequently, the mounting blocks 203 need to be operated to rotate the clamping plate 207 on the hinge 206, thereby opening the clamping plate 207 and the arc-shaped plate 205. This design facilitates the internal rotating shaft 23 and... After cleaning the spiral disc 19, the operator only needs to close the clamp plate 207 and tighten the bolt 204 to re-fix the soil sampler. The whole operation process is simple and quick, which is convenient for disassembly and cleaning, significantly improving work efficiency and equipment maintenance convenience. The left and right ends of the front side of the outer wall of the door panel 9 are fixedly connected to handles 10. The outer sides of the two handles 10 are rotatably connected to anti-slip sleeves 11. The bottom wall of the base 1 is equidistantly rotatably connected to multiple support rods 12. The upper and lower ends of the outer wall of the support rods 12 are fixedly connected to limit blocks 14. The support rods 12 provide necessary support for the soil sampler, enabling it to maintain a stable posture. Especially when drilling into deeper soil layers, the support rods 12 can withstand the weight of the soil sampler and various forces generated during drilling, preventing the soil sampler from tilting or shaking, and ensuring the accuracy and quality of soil sampling.
[0042] Specifically, after the soil is removed, the second rotating bolt 204 is used to remove it from the mounting block 203. The mounting block 203 is then pried open so that the second clamping plate 207 rotates on the second hinge 206, which opens the second clamping plate 207 and the arc plate 205. The internal rotating shaft 23 and spiral disc 19 are then cleaned. After cleaning, the second clamping plate 207 is closed, and the second bolt 204 is tightened to fix it in place. The operation is convenient and easy to disassemble and clean.
[0043] Reference Figure 1 , Figure 2 and Figure 3 The inner wall of the support rod 12 is slidably connected to the support leg 13, the end of the support leg 13 is fixedly connected to the tip 15, the left side of the end of the support leg 13 is installed with the fixing plate 16, and the bottom wall of the fixing plate 16 is threadedly connected to the bolt 17.
[0044] Specifically, place the pointed end 15 on the ground, adjust the angle of the fixing plate 16, and then rotate the bolt 17. When the bolt 17 is rotated to the ground, it will drill into the ground and be difficult to remove, thus firmly fixing the outrigger 13 to the ground and providing strong grip for the equipment.
[0045] Working principle: In this design, the bottom end of gear 21 is fixedly connected to the rotating shaft 23. When the motor 4 starts to rotate, it drives gear 20 to rotate as well. A spiral disk 19 is fixedly connected to the outer wall of the rotating shaft 23. Gear 20 and gear 21 interact with each other through meshing. Therefore, when gear 20 drives gear 21 to rotate, it can effectively drive the rotating shaft 23 and spiral disk 19 to rotate together. The addition of drill bit 22 can not only significantly improve the soil sampler's compressive strength and wear resistance, but also greatly improve the drilling efficiency in hard strata. After drill bit 22 drills into the ground, spiral disk 19 will continue to rotate, transporting the soil collected by drill bit 22 upwards, so that the soil can be smoothly discharged from discharge bin 18, greatly improving the convenience of soil sampling.
[0046] After the soil sampling is completed, the operator can remove the soil sampler from the mounting block 203 by rotating bolt 204. Next, the operator needs to pry the mounting block 203, so that clamp 207 will rotate on hinge 206, thereby opening clamp 207 and arc plate 205. This design makes it easy to clean the internal rotating shaft 23 and spiral disc 19. After cleaning, the operator only needs to close clamp 207 and tighten bolt 204 to fix the soil sampler back in place. The whole operation process is very convenient, and it also facilitates disassembly and cleaning, greatly improving work efficiency and equipment maintenance convenience.
[0047] 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.
