Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, and in particular to a portable sampler for geological exploration. Background Technology

[0002] Geological exploration equipment consists of specialized tools and instruments used for geological surveys, exploration, and resource assessment. These devices help geologists and engineers identify the distribution, properties, and reserves of underground resources. Among these are geological exploration samplers, which are tools specifically designed to collect geological samples. These samples are then used to analyze geological structures, rock composition, and soil properties. Types of samplers include core drills for drilling undisturbed rock cores, core drill bits suitable for obtaining continuous rock samples, core tubes used in conjunction with drill bits to hold and protect core samples, and soil drills suitable for different soil types, equipped with piston samplers that push soil samples into the sampling tube by the pressure of a piston.

[0003] A search revealed Chinese Patent Publication No. CN221078088U, which discloses a sampler for geological exploration, comprising a cylinder, a drill bit, and a fixing block. The drill bit is fixedly connected to the bottom of the cylinder. A threaded hole is opened in the center of the upper surface of the fixing block, and threads are provided on the side wall. The cylinder is threadedly connected to the center of the fixing block, and threads are provided on the inner wall of the cylinder. A material collection device is threadedly connected inside the cylinder. The material collection device includes a reinforcing support, a connecting column, and a material collection box. The reinforcing support is threadedly connected inside the cylinder, and the connecting column is fixedly connected to the center of the bottom of the reinforcing support. A material collection box is fixedly connected to the center of the bottom of the connecting column, and a gap is left between the material collection box and the reinforcing support. Drill teeth are fixedly connected around the drill bit, and the shape is an isosceles triangle. A collection hole is opened in the center of one side of the drill teeth. One end of the collection hole is located in the center of one side of the drill teeth, and the other end is located on the side wall of the cylinder. The collection hole is opened parallel to the side of the drill teeth where no hole is opened. It has the function of eliminating impurities and interference and can repeatedly sample. However, its structure is relatively complex and cannot be folded, making it more troublesome to carry, resulting in reduced portability and practicality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a portable sampler for geological exploration, aiming to improve the problem that the existing geological exploration samplers have a complex structure and cannot be folded, making them inconvenient to carry, resulting in reduced portability and practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable sampler for geological exploration, comprising a frame, rotating grooves on both the left and right sides of the frame, multiple sliding grooves on the inner wall of the frame, a rotating block rotatably connected to the front of the frame, a hollow rotating shaft rotatably connected to the inner wall of the sliding groove, a rotating frame fixedly connected to the outer wall of the hollow rotating shaft, a locking rod slidably connected to the inner wall of the hollow rotating shaft, a connecting rod fixedly connected to the front of the locking rod, a positioning groove on the inner wall of the connecting rod, an asynchronous motor fixedly connected to the top of the frame, a mounting shaft fixedly connected to the output end of the asynchronous motor, a sampling rod threadedly connected to the inner wall of the mounting shaft, a positioning plate fixedly connected to the outer wall of the sampling rod, and multiple support mechanisms fixedly connected to the top of the frame near the edge, the support mechanisms being used for auxiliary support during sampling.

[0006] The above technical solution uses an asynchronous motor as the power source for the entire sampler. The mounting shaft and sampling rod are connected by a thread. This connection method not only facilitates the installation and removal of the sampling rod, but also allows for flexible replacement of sampling rods of different specifications according to different geological conditions and sampling depth requirements. The support mechanism can be adjusted according to different ground conditions to ensure that the frame remains stable on various complex terrains. The slide can be used to cooperate with the positioning plate to place the disassembled sampling rod.

[0007] As a further description of the above technical solution: The support mechanism includes a fixing block, the bottom of which is fixedly connected to the top of the frame. A first pin is slidably connected to the inner wall of the fixing block. A limiting disc is provided on the outer wall of the first pin. A support rod is fixedly connected to the bottom of the limiting disc. A sliding rod is slidably connected to the inner wall of the support rod. Multiple locking holes are provided on the outer wall of the support rod. A second pin is slidably connected to the inner wall of each locking hole. A limiting disc is fixedly connected to the rear end of the second pin. A locking groove is provided on the inner wall of the second pin. A U-shaped ring is slidably connected to the inner wall of the locking groove. A support plate is threaded to the bottom end of the sliding rod.

[0008] Through the above technical solutions: the support plate can increase the contact area with the ground, improve the stability of the support mechanism under different ground conditions, disperse the pressure of the support mechanism, prevent the sampler from sinking into the ground, and at the same time provide reliable friction to prevent the sampler from sliding. The limiting plate can effectively prevent the second pin from accidentally falling off after being inserted into the card hole. After the second pin is inserted into the card hole, the operator can insert the U-shaped ring into the card slot to further enhance the locking stability of the second pin and ensure that the support mechanism will not change height due to external force during the sampling operation.

[0009] As a further description of the above technical solution: A protective shell is fixedly connected to the center of the top surface of the frame, and the outer wall of the protective shell has multiple heat dissipation grooves.

[0010] The above technical solution provides a protective shell for protecting the internal structure.

[0011] As a further description of the above technical solution: A controller is fixedly connected to the top of the protective shell, and the controller is electrically connected to the asynchronous motor.

[0012] The above technical solution provides a controller that helps users control the electrical mechanisms within the device.

[0013] As a further description of the above technical solution: A rubber pad is fixedly connected to the outer wall of the positioning disk, and a sampling sleeve is fixedly connected to the bottom of the positioning disk.

[0014] Through the above technical solution: the rubber pad 2 is used to buffer the structure that contacts the outer wall of the positioning disk.

[0015] As a further description of the above technical solution: An anti-slip sleeve is fixedly connected to the outer wall of the first pin, and a rubber pad is fixedly connected to the bottom of the support plate.

[0016] Through the above technical solution, the anti-slip sleeve can increase the friction of the outer wall of the first pin.

[0017] As a further description of the above technical solution: A rubber sleeve is fixedly connected to the outer wall of the rotating block, and the outer wall of the rubber sleeve fits against the inner wall of the positioning groove.

[0018] Through the above technical solution, the rubber sleeve can increase the friction of the outer wall of the rotating block.

[0019] As a further description of the above technical solution: The inner wall of the rotating frame is fixedly connected with a reinforcing rod, and the outer walls of the multiple rotating frames are fixedly connected with anti-slip sleeves.

[0020] The above technical solution involves reinforcing rods used to strengthen the overall structure of the rotating frame.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the sampling rod is rotated out of the mounting shaft and then inserted into the slide groove. Its position is limited by the positioning plate. Then, the rotating block is rotated so that the connecting rod can pass outward through the positioning groove, thereby pulling out the locking rod and releasing the limitation on the hollow rotating shaft. Then, the hollow rotating shaft is rotated to drive the rotating frame to fold. Finally, the locking rod is reinserted into the hollow rotating shaft, thus achieving the purpose of the folding and storage device structure, improving portability and practicality.

[0022] 2. In this utility model, by inserting the support rod between adjacent fixed blocks and limiting it by inserting the first pin into the fixed block through the limiting plate, then pulling the sliding rod down along the support rod to move the support plate to the appropriate position, inserting the second pin into the card hole to limit the sliding rod, and then inserting the U-shaped ring into the card groove to limit the second pin, the purpose of adjustable support for the device is achieved, which improves practicality, expands the scope of application, and reduces labor intensity.

[0025] 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.

[0026] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a portable sampler for geological exploration, comprising a frame 1 for supporting and mounting the entire structure. Rotation slots 14 are provided on both the left and right sides of the frame 1, and multiple sliding grooves 13 are provided on the inner wall of the frame 1. A rotating block 12 is rotatably connected to the front of the frame 1. A hollow rotating shaft 8 is rotatably connected to the inner wall of the sliding groove 13. The rotation slots 14 provide space for the rotation of the remaining structures. A rotating frame 3 is fixedly connected to the outer wall of the hollow rotating shaft 8, and a locking rod 9 is slidably connected to the inner wall of the hollow rotating shaft 8. The rotating frame 3 is used to assist in sampling. Holding the device, a connecting rod 11 is fixedly connected to the front side of the clamping rod 9. The inner wall of the connecting rod 11 is provided with a positioning groove 10. An asynchronous motor 4 is fixedly connected to the top of the frame 1. The connecting rod 11 is used to connect multiple clamping rods 9 to move synchronously. The output end of the asynchronous motor 4 is fixedly connected to a mounting shaft 5. A sampling rod 7 is threadedly connected to the inner wall of the mounting shaft 5. A positioning disk 6 is fixedly connected to the outer wall of the sampling rod 7. The mounting shaft 5 is used to connect the sampling rod 7. Multiple support mechanisms 2 are fixedly connected to the top of the frame 1 near the edge. The support mechanisms 2 are used for auxiliary support during sampling. The sampling rod 7 can be sampled by rotation. Specifically, when it is necessary to carry the sampler to the exploration site, some parts can be folded through the rotating slot 14 to effectively reduce the size of the equipment and facilitate transportation. When the equipment is unfolded upon arrival at the destination, the rotating slot 14 can ensure that the parts are smoothly unfolded to the working state, ensuring the normal operation of the equipment. After the rotating frame 3 is adjusted to the required angle, it is locked into the corresponding positioning slot 10 by sliding the lever 9, thereby firmly locking the rotating frame 3 to prevent shaking or displacement during the sampling process and ensuring the accuracy and stability of the sampling operation.

[0027] Please see the appendix Figure 2 - Appendix Figure 4 The support mechanism 2 includes a fixing block 204, the bottom of which is fixedly connected to the top of the frame 1. A first pin 202 is slidably connected to the inner wall of the fixing block 204. A limit plate 203 is provided on the outer wall of the first pin 202. The fixing block 204 is used to limit the position of the limit plate 203 in conjunction with the first pin 202. A support rod 206 is fixedly connected to the bottom of the limit plate 203. A sliding rod 207 is slidably connected to the inner wall of the support rod 206. A plurality of locking holes 205 are provided on the outer wall of the support rod 206. The inner wall of 05 is slidably connected to a second pin 208. The support rod 206 is used to provide guidance for the sliding of the sliding rod 207. The rear end of the second pin 208 is fixedly connected to a limiting plate 211. The inner wall of the second pin 208 is provided with a slot 210. The limiting plate 211 can limit the position of the rear end of the second pin 208. The inner wall of the slot 210 is slidably connected to a U-shaped ring 209. The bottom end of the sliding rod 207 is threadedly connected to a support plate 201. The U-shaped ring 209 can limit the other end of the second pin 208. Specifically, the support mechanism 2 is based on the fixed block 204 as a connecting component, ensuring that there will be no loosening or displacement between the support mechanism 2 and the frame 1 in complex exploration operation environments. The limiting plate 203 not only prevents the first pin 202 from disengaging from the fixed block 204 during sliding, but also provides an initial positioning reference for the height adjustment of the entire support mechanism 2 through the limiting cooperation with the fixed block 204. When it is necessary to adjust the height of the support mechanism 2, the operator can first pull out the second pin 208, and then extend and retract the sliding rod 207 in the support rod 206 to a suitable position according to the actual terrain requirements, and then insert the second pin 208 into the corresponding locking hole 205.

[0028] Please see the appendix Figure 4 - Appendix Figure 6A protective shell 18 is fixedly connected to the middle of the top surface of the frame 1. The outer wall of the protective shell 18 has multiple heat dissipation grooves 19. The protective shell 18 is used to protect the electrical structure inside. A rubber pad 21 is fixedly connected to the outer wall of the positioning disk 6. A sampling sleeve 22 is fixedly connected to the bottom of the positioning disk 6. A controller 17 is fixedly connected to the top of the protective shell 18. The controller 17 is electrically connected to the asynchronous motor 4. The sampling sleeve 22 is used to be inserted into the ground for sampling. Specifically, during long-term continuous operation, components such as the asynchronous motor 4 of the sampler will generate a large amount of heat. The heat dissipation groove 19 can dissipate this heat in time, preventing the equipment from degrading or malfunctioning due to overheating, and ensuring that the sampler is always in a stable and reliable operating state. The rubber pad 21 can effectively absorb and buffer these external forces, reducing the direct impact on the positioning plate 6 and sampling rod 7, and avoiding damage to the components. The sampling sleeve 22 can collect the geological sample completely as the sampling rod 7 goes deeper, providing accurate and reliable samples for subsequent geological analysis.

[0029] Please see the appendix Figure 3 - Appendix Figure 5 The outer wall of the first pin 202 is fixedly connected with an anti-slip sleeve 15, and the bottom of the support plate 201 is fixedly connected with a rubber pad 20. The anti-slip sleeve 15 can increase the friction of the outer wall of the first pin 202. The inner wall of the rotating frame 3 is fixedly connected with a reinforcing rod 24. The outer walls of multiple rotating frames 3 are all fixedly connected with anti-slip sleeves 26. The outer wall of the rotating block 12 is fixedly connected with a rubber sleeve 23. The reinforcing rod 24 can improve the stability of the rotating frame 3. The outer wall of the rubber sleeve 23 fits against the inner wall of the positioning groove 10. The anti-slip sleeve 26 can increase the friction of the outer wall of the rotating frame 3. Specifically, the rubber pad 20 can fit tightly against the ground, fill the tiny gaps in the ground, and effectively disperse the pressure of the sampler. Therefore, the rubber pad 20 can significantly enhance the stability of the sampler, prevent it from tipping over or shifting, and provide solid support for the sampling work. The reinforcing rod 24 can effectively disperse stress, prevent the rotating frame 3 from deforming, improve the overall strength and stability of the rotating frame 3, and ensure that it maintains reliable performance during long-term use.

[0030] Working principle: When the device is not in use, firstly, the sampling rod 7 is disassembled from the internal thread of the mounting shaft 5 by rotating it, and then inserted into the slide groove 13. The position of the sampling rod 7 is limited by the positioning plate 6 to prevent it from falling off during transportation. Then, the rotating block 12 is rotated so that the outer wall of the rotating block 12 coincides with the inner wall of the positioning groove 10. Then, the connecting rod 11 is pulled outward to disengage from the rotating block 12. Then, the hollow rotating shaft 8 is rotated in the rotating groove 14 to rotate and adjust the rotating frame 3 to the bottom, thereby storing the structure. Finally, the locking rod 9 is reinserted into the hollow rotating shaft 8 to limit its rotation. At the same time, the rotating block 12 is inserted into the positioning groove 10, and the rotating block 12 is rotated to limit the position of the locking rod 9 by limiting the connecting rod 11. When sampling is required in areas with complex terrain and relatively hard geology, firstly, the support rod 206 is inserted into the frame 1 and its position is limited by the limiting plate 203. Then, the first pin 202 is inserted through the fixing block 204 and through the limiting plate 203 to limit its position. Next, the support plate 201 is threaded to the bottom end of the sliding rod 207. Then, the sliding rod 207 is pulled down along the support rod 206 so that it can drive the support plate 201 to a suitable position. Then, the second pin 208 is inserted into the card hole 205 to limit the position of the sliding rod 207 and is limited by the limiting plate 211. Finally, the north U-shaped ring 209 is inserted into the card slot 210 to limit the position of the second pin 208.

[0031] 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.
