Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration drilling devices, in particular to a geological exploration drilling device. Background Art

[0002] The patent with publication number CN220625830U discloses a soil layer drilling and sampling device for geological exploration, which relates to the technical field of soil layer drilling and sampling. It includes a base, and cylinders are respectively and fixedly installed at the four corners of the lower wall surface of the base. The upper and lower ends of the cylinders are respectively of an open structure. Loading boxes are respectively and fixedly installed at the four corners of the upper wall surface of the base. An electric push rod is fixedly installed on the inner upper wall surface of the loading box. In the utility model, the universal wheels are driven by the electric push rod to move out of and be retrieved into the cylinders, so that the base can be lifted and moved. When the cylinders contact the ground, the inclined puncture nails in the grounding assembly are used to improve the grip of the cylinders, and further improve the stability of the connection between the base and the ground. The lifting assembly drives the bearing plate and the sampling cylinder to move downward and insert into the ground. When the sampling cylinder is inserted into the ground, through the sampling assembly, the sampling cylinder samples the soil while moving downward. For traditional geological exploration drilling devices, manual adjustment and fixation are usually required, and the operation process is cumbersome and time-consuming. Especially when the sampling rod needs to be frequently replaced, this method significantly prolongs the operation time. Due to the lack of an effective quick-fixing mechanism in the traditional disassembly and assembly method, the stability of the sampling rod cannot be ensured, and it is easy to cause loss or contamination of the sample during the operation, which not only affects the sampling efficiency, but also may lead to inaccurate collected data, thus affecting the final research and analysis results, and improvement is needed.

However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

The sliding connection between the guide rod 3 and the lifting plate 4 improves the accuracy of the adjustment process and ensures the stability of the lifting plate 4 at different heights. The design of the electric telescopic rod 18 and the universal wheel 19 enables the device to have flexible mobility on various terrains. At the same time, the adjustment of the electric telescopic rod 18 provides additional positioning support, further improving the stability of the device and reducing the shaking caused by uneven ground. The output end of the motor A 6 is fixedly connected to the lead screw 5, and the lead screw 5 is threadedly connected to the lifting plate 4. The fixed connection between the motor A 6 and the lead screw 5 and its driving ability ensure the smoothness and continuity of the rotation of the lead screw 5. The threaded connection between the lifting plate 4 and the lead screw 5 makes the adjustment process smooth and precise, effectively avoiding jamming or errors that may occur during the lifting process. By controlling the rotation speed and direction of the motor A 6, the fine-tuning function of the lifting plate 4 can be realized, providing greater flexibility for drilling operations in complex geological environments. The fixing rod 11 is slidably connected to the clamping block 9, and the fixing block 13 is slidably connected to the installation block 8. The sliding connection between the fixing rod 11 and the clamping block 9 and the flexible design of the fixing block 13 and the installation block 8 not only enable the sampling rod 10 to be quickly positioned but also significantly simplify the disassembly and assembly steps, reducing the operation time. The precise fit of the sliding connection ensures the high-efficiency stability of the device even when the sampling rod 10 is replaced frequently at high frequencies, while improving the operation convenience during the drilling process. The connecting rod 15 is slidably connected to the fixing block 13, and one end of the pulling spring 17 is fixedly connected to the connecting block 14. The sliding connection between the connecting rod 15 and the fixing block 13, combined with the elastic action of the pulling spring 17, provides an efficient preliminary limiting and fixing function. The elastic design of the pulling spring 17 ensures that the connecting rod 15 can quickly reset. Even under frequent use, it can still maintain the precise limiting ability of the clamping block 9, further improving the durability and operation efficiency of the device and reducing the human error during the installation process.

[0023] Embodiment Two

[0024] See also Figures 1-4 The base 1 is internally rotatably connected to a threaded rod 20, one end of which is fixedly mounted with a rotating head 21. The bottom end of the threaded rod 20 is rotatably connected to a support block 22, which is internally slidably connected with a rivet 23. A scale plate 24 is fixedly mounted on the upper surface of the support block 22. The height of the support block 22 can be adjusted by rotating the threaded rod 20, which not only meets the adaptability requirements of the equipment under various terrain conditions, but also enables rapid adjustment through the flexible control of the rotating head 21. The combined design of the support block 22 and the rivet 23 enhances ground grip. At the same time, the self-locking feature of the threaded rod 20 prevents the support block 22 from slipping during vibration, further improving the operational stability of the equipment in complex geological environments. The scale plate 24 is slidably connected to the base 1, and the rivets 23 are symmetrically arranged on both sides of the support block 22. The sliding connection design of the scale plate 24 provides an intuitive observation function for adjusting the height of the support block 22, allowing the operator to quickly calibrate the position of the equipment and confirm the status of the support block 22. The symmetrical arrangement of the rivets 23 not only enhances the fixing effect of the device, but also further improves the stability of the device when subjected to forces in multiple directions, ensuring that the device will not be displaced due to external interference during use, and providing more reliable support for the drilling process.

[0025] Working principle: By controlling the electric telescopic rod 18 to adjust the position of the equipment, the equipment is smoothly positioned at the target drilling position with the help of the universal wheel 19, and then the motor A6 in the base 1 is started. The screw rod 5 is rotated through the fixed connection with the screw rod 5. The rotation of the screw rod 5 causes the lifting plate 4 to move up and down along the guide rod 3 through the threaded connection to adjust to the required drilling depth. This process is controlled by the speed and direction of the motor A6. After the lifting plate 4 is adjusted into place, the motor B7 is started to drive the mounting block 8. The operator manually operates the card block 9 inside the mounting block 8, inserts the sampling rod 10 into it, and pulls the connecting block 14, using the elastic force of the tension spring 17 to make the connecting block The connecting rod 15 slides into the inside of the fixing block 13 to complete the initial fixation of the sampling rod 10. Subsequently, by inserting the fixing rod 11 and sliding it to the specified position of the block 9 and the mounting block 8, the operator tightens the nut 12 on the fixing rod 11 to complete the secondary fixation of the sampling rod 10 to ensure its stability. After the preparation work is completed, the sampling rod 10 is started for drilling. The sampling rod 10 gradually enters the ground according to the geological conditions to complete the sample collection. After the drilling is completed, the nut 12 and the fixing rod 11 are loosened to release the block 9 and the sampling rod 10. With the help of the tension spring 17 and the connecting rod 15, the sampling rod 10 is easily disassembled and the internal sample is taken out.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
