Description

[0002] The field of geological engineering is based on natural science and earth science. It focuses on geological surveys, prospecting and exploration of mineral resources, and engineering problems related to the geological structure and background of major projects. In the process of coal mining, it involves gradually exploring the area around the coal-producing region to understand the coal reserves and the extent of the coal mining area, and using this data to judge the progress of coal mining.

[0003] Currently, soil sampling is required when conducting soil exploration of rock strata. The common method involves drilling into the rock strata and then extracting samples from the borehole wall for analysis. However, this method has certain drawbacks.

Traditional sampling equipment uses a motor to drive the drill bit at high speed, but the limited length of the drill bit restricts the drilling depth. Furthermore, longer drill bits are inconvenient to carry during field geological exploration. Therefore, it is necessary to provide a new sampling device for hydrogeological exploration to solve the aforementioned technical problems. Utility Model Content

The embodiments described below do not represent all embodiments consistent with this application. They are merely examples consistent with some aspects of this application as detailed in the claims.

[0035] See Figure 1 This is a schematic diagram of the overall structure of a sampling device for hydrogeological exploration provided in this application, including:

[0036] Mounting plate 3;

[0037] See Figure 3 This is a schematic diagram of the structure of the mounting plate of a sampling device for hydrogeological exploration provided in this application.

[0038] Rotate the four support legs 4 connected to the edge of the mounting plate;

[0039] The four support legs 4 are arranged in a circular array. The bottom of each of the four support legs 4 is rotatably mounted with a base plate, and each of the four base plates is movably mounted with a ground anchor.

[0040] The mounting plate 3 has a through hole at its center, and a fixed cylinder 1 is slidably connected inside the through hole;

[0041] See Figure 4 This is a schematic diagram of the structure of a fixed cylinder for a sampling device for hydrogeological exploration provided in this application. The fixed cylinder 1 is installed on the mounting plate 3 by a sliding connection. The internal space of the fixed cylinder 1 can be used to place sampling tools and provide a preliminary guiding function.

[0043] See Figure 2 This is a schematic diagram of the structure of a sampling device for hydrogeological exploration provided in this application. The fixed frame 5 is connected to the mounting plate 3 and is a column structure arranged around the fixed cylinder 1.

[0044] The fixing frame 5 is a columnar structure, shaped like the letter "n", and is arranged around the fixing cylinder 1 to support the lifting plate 7 and provide a track for vertical lifting. The fixing frame 5 is fixedly connected to the mounting plate 3 to ensure the stability of the entire lifting structure.

[0045] Telescopic cylinder 6 is installed on the top of the fixed frame 5;

[0046] The telescopic cylinder 6 is a commonly used multi-stage cylinder.

[0047] The lifting plate 7 is slidably connected within the column structure of the fixed frame 5;

[0048] The lifting plate 7 is slidably connected within the column structure of the fixed frame 5. The top of the lifting plate 7 is equipped with a motor 9, and the bottom is equipped with a connecting shaft 10. The lifting plate 7 is raised and lowered by the drive of the telescopic cylinder 6, and at the same time supports key components such as the motor 9 and the connecting shaft 10.

[0049] Both sides of the fixed frame 5 can be provided with strip-shaped openings, and a sliding rod is vertically fixedly installed in each of the two strip-shaped openings. Both sliding rods pass through the lifting plate 7 and are slidably connected to it.

[0050] The motor 9 is installed on the top of the lifting plate 7;

[0051] The motor 9 is mounted on the top of the lifting plate 7 and is connected to the connecting shaft 10 via a transmission mechanism. The rotation of the motor 9 drives the connecting shaft 10 to rotate, thereby driving the sampling tool to rotate and sample.

[0052] A connecting shaft 10 is rotatably connected to the bottom of the lifting plate 7, and the output shaft of the motor 9 is fixedly connected to the connecting shaft 10;

[0053] The connecting shaft 10 is rotatably connected to the bottom of the lifting plate 7, and the lower end of the connecting shaft 10 is connected to the sampling tool. The rotational movement of the connecting shaft 10 is provided by the motor 9, realizing the rotational sampling of the sampling tool.

[0054] A connecting frame 8 is fixedly connected to the top of the lifting plate 7, and the connecting frame 8 is arranged around the motor 9;

[0055] The connecting frame 8 is arranged around the motor 9, and the top of the connecting frame 8 is fixedly connected to the output shaft of the telescopic cylinder 6. The connecting frame 8 not only connects the telescopic cylinder 6 and the lifting plate 7, but also protects the motor 9.

[0056] The output shaft of the telescopic cylinder 6 is fixedly connected to the top of the connecting frame 8;

[0057] The telescopic cylinder 6 is mounted on the top of the fixed frame 5, and its output shaft is fixedly connected to the connecting frame 8 on the top of the lifting plate 7. The telescopic movement of the telescopic cylinder 6 is used to drive the lifting plate 7 to move vertically up and down within the fixed frame 5.

[0058] A screw conveyor 21 is rotatably connected to the center of the fixed cylinder 1. A drill bit 22 is fixedly connected to the bottom end of the screw conveyor 21 inside the fixed cylinder 1. A connecting cylinder 23 and a filter cylinder 24 are also fixedly connected to the end of the drill bit 22. The top end of the filter cylinder 24 is fixedly connected to the bottom end of the fixed cylinder 1.

[0059] The auger 21 inside the fixed cylinder 1 is longer than the auger 21 inside the splicing cylinder 2. The bottom end of the auger 21 inside the fixed cylinder 1 extends to the bottom of the fixed cylinder 1, while the bottom end of the auger 21 inside the splicing cylinder 2 is located above the two positioning rods 25.

[0060] This application mainly consists of a fixed cylinder 1 and a splicing cylinder 2, both of which are rotatably connected to an auger 21 at their internal center. The auger 21 is designed to easily break up soil or rock and bring it into the cylinder during sampling. Inside the fixed cylinder 1, a drill bit 22 is fixedly connected to the bottom end of the auger 21. The drill bit 22 is used to drill into the soil or rock during sampling to obtain samples from deeper layers. To further improve the efficiency and accuracy of sampling, a connecting cylinder 23 and a filter cylinder 24 are also fixedly connected to the top of the drill bit 22. The connecting cylinder 23 ensures a stable connection between the drill bit 22 and the auger 21, while the filter cylinder 24 is used to filter out impurities that may be mixed in during sampling, such as stones and large soil particles, thereby ensuring that the obtained sample is pure and uniform.

[0061] The top of the filter cartridge 24 is fixedly connected to the bottom of the fixed cartridge 1, forming a complete sampling system. When the auger 21 rotates, soil or rock enters the connecting cartridge 23 through the drill bit 22, and then passes through the filter cartridge 24 before finally entering the fixed cartridge 1 or the splicing cartridge 2. This design makes the sampling process more efficient and accurate, and is suitable for various complex geological environments.

[0062] Furthermore, it also includes:

[0063] At least one splicing cylinder 2, which is spliced ​​together and detachably connected to the fixed cylinder 1, and the splicing cylinder 2 is also connected to the auger 21 for rotational rotation at its internal center.

[0064] Furthermore, two vertical plates 11 are fixedly connected to the bottom ends of the lifting plate 7, and a loading tray 12 is fixedly connected between the two vertical plates 11. The loading tray 12 is circular in shape.

[0065] The top of the carrying tray 12 has a recessed notch, and the center of the notch has a circular opening. Two vertical plates 11 are fixedly connected to the bottom ends of the lifting plate 7, and a circular carrying tray 12 is securely connected between these two vertical plates 11. This design allows the lifting plate 7 to stably support and secure various tools or equipment during lifting, enhancing the overall structural stability and functionality. Whether for industrial applications or scientific research experiments, this design provides convenience and safety.

[0066] See Figure 5 This is a schematic diagram of the structure of a splicing tube for a hydrogeological sampling device provided in this application. Further, two abutment strips 13 are fixedly connected to the outer walls of both the fixed tube 1 and the splicing tube 2. Two upright plates 14 are also fixedly connected to both sides of the mounting plate 3. A limiting rod 15 is inserted into each of the two upright plates 14. The two ends of the two limiting rods 15 are slidably inserted into the two ends of two clamping plates 18. Four hinge rods 16 are rotatably connected to the ends of the two clamping plates 18. Pressing blocks 17 are rotatably installed on the two hinge rods 16 on the same side.

[0067] Two abutment strips 13 are fixedly installed on the outer walls of both the fixed cylinder 1 and the splicing cylinder 2. The two abutment strips 13 are located near the top of the fixed cylinder 1 and the splicing cylinder 2, and are symmetrically arranged around the center of either the fixed cylinder 1 or the splicing cylinder 2. Two upright plates 14 are fixedly installed on the top of the mounting plate 3. Limiting rods 15 are fixedly installed on each of the two upright plates 14. Two clamping plates 18 are slidably installed on the two limiting rods 15. The middle of the two clamping plates 18 is arc-shaped and can fit against the outer wall of the fixed cylinder 1 or the splicing cylinder 2. Two springs are sleeved on each of the two limiting rods 15. One end of each of the four springs is fixedly connected to one side of the outer wall of the two upright plates 14, and the other end of each of the four springs is fixedly connected to the two clamping plates 18. Specifically, as shown... Figure 3 As shown, hinge rods 16 are rotatably mounted on both ends of the two clamping plates 18, and pressing blocks 17 are rotatably mounted on the corresponding two hinge rods 16.

[0068] Two slide rails are symmetrically welded on the outer walls of both the fixed cylinder 1 and the splicing cylinder 2. Two slide rails are fixedly installed on the inner wall of the mounting plate 3, and the two slide rails are respectively matched with the two slide rails.

[0069] See Figure 6This is a schematic diagram of the connection structure between the splicing cylinder and the carrying tray of a sampling device for hydrogeological exploration provided in this application. Furthermore, the top of both the fixed cylinder 1 and the splicing cylinder 2 is welded with a threaded cylinder 19, and two positioning holes 20 are opened on the outer wall of the threaded cylinder 19. Positioning rods 25 are movably installed on the outer walls of both the fixed cylinder 1 and the splicing cylinder 2.

[0070] The external thread of the threaded cylinder 19 is about two-thirds of the overall height of the threaded cylinder 19. The two positioning holes 20 are located above the external thread and are symmetrically opened based on the midpoint of the threaded cylinder 19. Similarly, in actual production, the inner walls of the fixed cylinder 1 and the splicing cylinder 2 are provided with internal threads, which are located at the bottom edge of the fixed cylinder 1 and the splicing cylinder 2.

[0071] The design of the threaded cylinder 19 not only enhances the structural stability but also facilitates the connection of sampling tools. Two positioning holes 20 are also provided on the outer wall of the threaded cylinder 19 for precise positioning with the positioning rod 25.

[0072] Positioning rods 25 are movably mounted on the outer walls of both the fixed cylinder 1 and the splicing cylinder 2. When sampling is required, the sampling tool is connected to the threaded cylinder 19 via threads, and the positioning rods 25 are adjusted to insert them into the corresponding positioning holes 20, thereby ensuring a stable connection between the sampling tool and the fixed cylinder 1 or the splicing cylinder 2. This design not only improves sampling accuracy but also enhances safety during the sampling process. After sampling, the positioning rods 25 can be adjusted to disengage from the positioning holes 20, facilitating the disassembly and replacement of the sampling tool.

[0073] Furthermore, each of the two augers 21 has a hexagonal groove 26 at its top end, and an embedding block 27 is installed at the bottom end of the auger 21 inside the splicing cylinder 2 and at the bottom end of the connecting shaft 10. The embedding block 27 matches the shape of the hexagonal groove 26.

[0074] To facilitate quick assembly and disassembly of the augers, both augers 21 are designed with hexagonal grooves 26 at their top ends. Embedding blocks 27 are installed at the bottom ends of the augers 21 inside the splicing cylinder 2 and at the bottom end of the connecting shaft 10. The shape of these embedding blocks 27 perfectly matches the hexagonal grooves 26 at the top ends of the augers 21. When it is necessary to remove the augers 21 from the fixed cylinder 1 or the splicing cylinder 2, simply align the corresponding embedding block 27 with the hexagonal groove 26 at the top end of the auger 21, rotate the auger, and the auger will be separated from the fixed cylinder or the splicing cylinder.

[0075] This design not only simplifies the assembly and disassembly of the auger and improves work efficiency, but also facilitates cleaning, maintenance, and replacement of the auger. Furthermore, the embedded design of the connection between the auger and the fixed and splicing cylinders ensures the stability and sealing of the connection, effectively preventing soil or rock leakage during sampling.

[0076] During use, staff can first use the four support legs 4 to fix the mounting plate 3 at the sampling position and position it using a ground anchor.

[0077] At this time, if Figure 1 As shown in the diagram, the worker can place the splicing tube 2 above the fixed tube 1 and fix the splicing tube 2 to the threaded tube 19 at the top of the fixed tube 1 by screwing it in. During the rotation, it is necessary to insert the embedding block 27 at the bottom of the auger 21 inside the splicing tube 2 into the hexagonal groove 26 at the top of the auger 21 inside the fixed tube 1.

[0078] After the splicing cylinder 2 is fully inserted into the threaded cylinder 19, the fixing strength between the two is further strengthened by screwing the positioning rod 25 on the outer wall of the splicing cylinder 2 into the two positioning holes 20 on the outer wall of the threaded cylinder 19 on the fixed cylinder 1. Then, the operator can start the telescopic cylinder 6. The output shaft of the telescopic cylinder 6 extends and drives the connecting frame 8 and the lifting plate 7 to move downward, so that the loading tray 12 is finally fitted onto the outer wall of the threaded cylinder 19 at the top of the splicing cylinder 2. At the same time, the embedded block 27 on the connecting shaft 10 enters the hexagonal groove 26 at the top of the auger 21 inside the splicing cylinder 2. At this time, the motor 9 is started. The output shaft of the motor 9 rotates and drives the connecting shaft 10 to rotate, thereby driving the auger 21 inside the splicing cylinder 2 to rotate. The auger 21 inside the fixed cylinder 1 and the drill bit 22 at the bottom rotate. At this time, the pressing blocks 17 on both sides are pressed, causing the clamping plates 18 on both sides to move away from each other and separate from the contact strip 13 on the outer wall of the fixed cylinder 1. With the cooperation of the telescopic cylinder 6, the drill bit 22 gradually moves downward and finally contacts the ground to perform drilling operations. When the drill bit 22 penetrates below the ground, the gravel generated by the high-speed rotation of the drill bit 22 will enter the connecting cylinder 23. Some small gravel will enter its interior through the filter cylinder 24. At this time, the rotation of the auger 21 will transport these small gravel upward and finally discharge them from the top of the splicing cylinder 2 into the loading tray 12. At this time, the workers can collect the gravel in the loading tray 12.

[0079] After the fixed cylinder 1 is completely submerged below the ground, the contact strip 13 on the outer wall of the splicing cylinder 2 will contact the clamping plates 18 on both sides and will not be able to continue descending. The operator can then activate the telescopic cylinder 6 in reverse to move the lifting plate 7 upward and separate it from the first splicing cylinder 2. The second spare splicing cylinder 2 will then be installed above the first splicing cylinder 2. After installation, the telescopic cylinder 6 will be activated again to lower its output shaft, thus allowing the drilling and sampling operation to be completed again in the above manner.

[0080] This application provides a schematic diagram of the overall structure of a sampling device for hydrogeological exploration, including a mounting plate 3; four support legs 4 rotatably connected to the edge of the mounting plate 3; a through hole at the center of the mounting plate 3, into which a fixed cylinder 1 is slidably connected; a fixed frame 5 connected to the mounting plate 3, the fixed frame 5 being a columnar structure surrounding the fixed cylinder 1; a telescopic cylinder 6 disposed at the top of the fixed frame 5; a lifting plate 7 slidably connected within the columnar structure of the fixed frame 5; a motor 9 disposed at the top of the lifting plate 7; and a motor 9 rotatably connected to the lifting plate 7. 7. A connecting shaft 10 at the bottom, the output shaft of the motor 9 is fixedly connected to the connecting shaft 10; a connecting frame 8 is fixedly connected to the top of the lifting plate 7, the connecting frame 8 is arranged around the motor 9; the output shaft of the telescopic cylinder 6 is fixedly connected to the top of the connecting frame 8; an auger 21 is rotatably connected to the center inside the fixed cylinder 1, a drill bit 22 is fixedly connected to the bottom end of the auger 21 inside the fixed cylinder 1, the end of the drill bit 22 is also fixedly connected to a connecting cylinder 23 and a filter cylinder 24, the top end of the filter cylinder 24 is fixedly connected to the bottom end of the fixed cylinder 1.

[0081] This application provides a sampling device for hydrogeological exploration. When conducting field geological exploration and sampling, the multiple splicing tubes used in this application are interconnected, which can extend the drilling depth, thereby solving the problem of drill bit length. In addition, during the sampling process, the soil sample can be quickly discharged upward through the auger. The whole process is not only simple and convenient, but also allows the drill bit length to be adjusted according to needs, thereby improving the efficiency of soil sampling.
