Description

Technical Field

[0001] The invention relates to the technical field of geological exploration, in particular to a mining geological exploration drilling sampling device. Background Art

[0002] In the fields of mining resource development and geological research, drilling and sampling for mine geological exploration is a key step in obtaining underground geological information. Its results directly impact mine resource assessment, mining plan design, and geological disaster prediction. As mining extends to deeper and more complex geological areas, higher requirements are placed on the performance and reliability of drilling and sampling equipment.

[0003] Currently, common mining and geological exploration drilling and sampling devices on the market have numerous limitations. Most rely on external power sources or fuel generators for energy supply. This severely limits the device's endurance in remote mountainous areas, deserts, and other areas lacking power infrastructure or where fuel transportation is difficult. Frequent energy replenishment not only increases operating costs but also reduces efficiency. Furthermore, fuel generators generate noise and exhaust, polluting the surrounding environment and failing to meet the requirements of environmentally friendly exploration operations.

[0004] In terms of ease of use and mobility, traditional drilling equipment is often bulky and heavy, lacking flexible movement and angle adjustment capabilities. In complex mining environments, the equipment is difficult to quickly move to the target drilling point and maintain stability on uneven ground. Operators need to expend considerable effort on equipment handling and commissioning, resulting in high workload and low efficiency.

[0005] In terms of drilling accuracy, traditional equipment lacks real-time monitoring and feedback mechanisms. During the drilling process, key parameters such as torque, tilt angle, and vibration cannot be obtained in a timely manner, making it difficult to adjust drilling strategies according to changing geological conditions. This can easily lead to problems such as deviation in drilling direction and increased drill bit wear, affecting the accuracy and completeness of sampling, leading to deviations in geological exploration data and increasing risks in subsequent resource assessment and mining planning.

[0006] Therefore, we propose a mining geological exploration drilling sampling device to solve the above-mentioned problems.

[0045] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0046] Example 1

[0047] A mining geological exploration drilling sampling device, comprising:

[0048] The outer shell 10 has a drive assembly inside, which drives the drilling structure to perform drilling and sampling. The drive assembly includes a motor 11, the output shaft of the motor 11 is connected to an elastic coupling 12, and the side of the elastic coupling 12 away from the motor 11 is connected to an electromagnetic clutch 13, and a reduction gear 14 is installed on the electromagnetic clutch 13. The reduction gear 14 is connected to a drill pipe joint 16, and the drill pipe joint 16 passes through the outside of the outer shell 10.

[0049] Specifically, Motor 11 uses a 48V brushless DC motor with a built-in Hall effect sensor for closed-loop control. It is secured to the motor base of the outer housing 10 via 4 x M8 bolts. Its output shaft is connected to an elastic coupling 12. The elastic coupling 12 provides elasticity and cushioning properties, effectively compensating for angular deviation and axial displacement between Motor 11 and subsequent transmission components, reducing vibration and noise. It also absorbs impact loads, protecting Motor 11 and other transmission components.

[0050] The outer shell 10 is the core load-bearing structure of the entire device. It is made of high-strength metal material with impact and pressure resistance, and can protect the internal drive components and sensor components from the complex environment of the mine. The outer shell 10 is provided with an installation space inside for fixing the drive components; the external symmetrically connected arc handle 72 is ergonomically designed, and the rubber pad 71 on its surface not only increases the comfort when holding, but also has an anti-slip effect, making it easier for operators to carry and operate the device. The control switch 70 set in the center of one of the arc handles 72 is electrically connected to the motor 1 11, electromagnetic clutch 13, motor 2 43, temperature sensor 81, tilt sensor 80, vibration accelerometer 83, torque sensor 15 and other components through internal wiring. The operator can use the control switch 70 to start, stop and monitor parameters of each component.

[0051] The power is engaged and disengaged through electromagnetic force. When the electromagnetic clutch 13 is energized, the power of the motor 11 can be transmitted to the reduction box 14; when the power is off, the power transmission is cut off, which facilitates the flexible control of the start and stop of the drilling action according to actual needs during the drilling process, thereby improving the safety and flexibility of the operation.

[0052] Reducer 14 utilizes a multi-stage gear transmission structure, converting the high speed and low torque of motor 11 into the low speed and high torque required by drill pipe joint 16, meeting the torque requirements during drilling and sampling. Reducer 14 and drill pipe joint 16 are connected via a high-precision mechanical interface, ensuring stable and reliable power transmission.

[0053] The drill rod joint 16 extends through the exterior of the outer casing 10 and is secured to the casing 20 via bolt blocks 21 and a long clamping block. A torque sensor 15 is connected to the exterior of the drill rod joint 16, near the reduction gearbox 14. This torque sensor 15 monitors the torque changes of the drill rod in real time during drilling and transmits this data to the data processing system associated with the control switch 70, enabling operators to keep abreast of drilling conditions.

[0054] The drilling mechanism includes a support rod 41, with both sides connected to the inner wall of a storage tube 40. A protective shell 42 is attached to the outside of the support rod 41. A second motor 43 is mounted inside the protective shell 42 via a base. The output shaft of the second motor 43 passes through the outside of the protective shell 42 via a second elastic coupling 44 and is connected to a drill bit 45. Saw teeth 46 are provided at one end of the storage tube 40.

[0055] Specifically, one end of the storage tube 40 is provided with serrations 46. Made of high-strength carbide, these serrations possess sharp edges and excellent wear resistance. At the start of drilling, they penetrate the ground, providing initial rock breaking and positioning. The storage tube 40 is threadedly connected to the fixed sleeve 90, facilitating easy removal and replacement. Different sizes of storage tubes 40 and drill bits 45 can be selected to suit different drilling requirements.

[0056] Both sides of the support rod 41 are firmly connected to the inner wall of the storage tube 40, providing a stable support structure for the protective shell 42 and the second motor 43. The support rod 41 is made of a high-strength metal rod with high strength and rigidity, which can withstand the various forces generated during the drilling process and ensure the stability of the drilling structure.

[0057] Motor 2 43 is mounted inside protective housing 42 via a base. Protective housing 42 features a sealed structure that effectively prevents dust, mud, water, and other impurities from entering, protecting the normal operation of motor 2 43. Protective housing 42 also has a certain heat dissipation function, dissipating the heat generated during operation of motor 2 43 in a timely manner to prevent damage to motor 2 43 due to overheating.

[0058] Motor 2 (43) provides rotational power to drill bit (45). Its output shaft extends through the exterior of protective housing (42) and is connected to drill bit (45) via elastic coupling (44). Elastic coupling (44) also has elastic and cushioning properties, ensuring smooth transmission of power from motor 2 (43) to drill bit (45) while reducing the effects of vibration on drill bit (45) and motor 2 (43).

[0059] The drill bit 45 can be a carbide drill bit, a diamond drill bit, or other different types of drill bits 45 depending on the geological conditions. The drill bit 45 is connected to the output shaft of the motor 2 43 via the elastic coupling 2 44 and rotates at high speed under the drive of the motor 2 43 to achieve drilling and sampling of the mine geology.

[0060] The outer shell 10 is provided with a power supply and support assembly, which includes two telescopic rods 50. The two telescopic rods 50 are connected to springs 54 on opposite sides. The springs 54 are connected to limit plates 53 on opposite sides. The limit plates 53 are connected to the outside of the limit bars 52. The solar tubes 51 are installed on the outside of the limit bars 52.

[0061] Specifically, the limiting bars 52 are semi-arc-shaped, and there are at least two of them, which are connected by a connecting rod.

[0062] A universal wheel 55 is mounted on the end of the telescopic rod 50, away from the connecting block 62. The universal wheel 55 rotates 360 degrees, facilitating mobility across varying terrains. Furthermore, the telescopic rod 50 can rotate along the curved groove 60 of the outer shell 10. The locking block 61 and connecting block 62 cooperate to maintain a fixed angle, allowing for both adjusting the orientation of the solar tube 51 for optimal solar light and adjusting the device's support angle for stability on uneven surfaces.

[0063] The two telescopic rods 50 are connected to opposite sides with springs 54. The springs 54 have a certain elasticity and can act as a buffer when the device moves or is impacted by external forces, thereby reducing damage to the solar tube 51 and other components. The opposite side of the spring 54 is connected to a limit plate 53. The limit plate 53 is used to limit the compression and extension range of the spring 54 to prevent excessive deformation of the spring 54. The outside of the limit plate 53 is connected to a limit bar 52. The limit bars 52 are semi-arc-shaped and there are at least two of them. They are connected by connecting rods to form a stable frame structure for fixing the solar tube 51. The design of the limit bar 52 can ensure that the solar tube 51 can be stably installed at different angles and facilitates the disassembly and maintenance of the solar tube 51.

[0064] An arcuate groove 60 is provided on the outside of the outer shell 10 , and a plurality of clamping blocks 61 are installed inside the arcuate groove 60 . The outside of the clamping blocks 61 is connected to a connecting block 62 , and the connecting block 62 is connected to the telescopic rod 50 via a limit hinge.

[0065] The outside of the drill rod joint 16 is fitted with the casing 20 , and bolt blocks 21 are passed through the inside of the casing 20 and the drill rod joint 16 , and the bolt blocks 21 are fixed by long clamping blocks.

[0066] Specifically, a circular groove is formed at one end of the bolt block 21 , and a long clamping block passes through the circular groove to fix the bolt block 21 to the drill pipe joint 16 and the casing 20 .

[0067] The exterior of the casing 20 fits snugly against the drill rod joint 16, while a bolt block 21 extends through it. A circular slot is defined at one end of the bolt block 21, through which a long clip secures the bolt block 21 to the drill rod joint 16 and the casing 20. This ensures a tight connection between the casing 20 and the drill rod joint 16, preventing loosening or falling off during drilling. An extension rod 30 is connected to the end of the casing 20 away from the outer housing 10. The extension rod 30 is adjustable in length based on the desired drilling depth and is threadedly connected to the fixed sleeve 90, facilitating easy installation and removal.

[0068] A battery pack 82 is provided inside the outer shell 10, a temperature sensor 81 is installed outside the battery pack 82 and on the side close to the motor 11, a tilt sensor 80 is installed in the center of the side of the outer shell 10 away from the drill pipe joint 16, and a vibration accelerometer 83 is installed inside the outer shell 10 near the side of the reduction gearbox 14.

[0069] Specifically, battery pack 82 utilizes a high-capacity lithium-ion battery pack capable of storing large amounts of energy, providing a stable power supply for the device. A temperature sensor 81 is mounted on the outside of battery pack 82, near motor 11. This sensor monitors the temperature of battery pack 82 in real time. If the temperature is too high or too low, it issues an alarm, prompting the operator to take appropriate measures to ensure safe operation of battery pack 82.

[0070] A tilt sensor 80 is mounted on the outside of the outer housing 10, at the center of one side away from the drill pipe joint 16, and monitors the device's tilt angle in real time. During drilling, the tilt sensor 80 transmits the data it detects to the display device or data processing system associated with the control switch 70. The operator can adjust the length and angle of the telescopic rod 50 based on the device's tilt angle to ensure the device remains level, improving the accuracy of drilling sampling.

[0071] A vibration accelerometer 83 is mounted inside the outer housing 10, near the reduction gearbox 14, to monitor the vibration of the device during drilling. By analyzing the vibration acceleration, it can determine whether there are any abnormalities during drilling, such as the drill bit 45 encountering hard rock or the drill rod bending. This information is promptly fed back to the operator, allowing them to take appropriate measures and resolve the situation.

[0072] One end of the sleeve 20 away from the outer shell 10 is connected to the extension rod 30 , one end of the extension rod 30 is threadedly connected to the fixing sleeve 90 , and the receiving tube 40 is threadedly connected to the other side of the fixing sleeve 90 .

[0073] The working principle of this embodiment is as follows: After the device arrives at the drilling site and is commissioned, the operator activates the drilling mechanism using the control switch 70 on the outer housing 10. This control switch 70 issues a start command to the second motor 43, which begins operating. The power output from the second motor 43 is transmitted to the drill bit 45 via the second elastic coupling 44. The second elastic coupling 44, with its elasticity and cushioning properties, not only compensates for angular deviation and axial displacement between the second motor 43 and the drill bit 45, reducing vibration and noise, but also provides a buffering effect when drilling encounters resistance, protecting the motor 43 and drill bit 45.

[0074] Driven by motor 2 43, drill bit 45 rotates at high speed. Depending on the geological conditions, the appropriate type of drill bit 45 is selected, such as a carbide drill bit for harder rock or a diamond drill bit for extremely hard rock formations. Its cutting edge continuously crushes and cuts the mining geology. The serrations 46 at one end of the storage tube 40 play a crucial role in the initial drilling phase. Their high strength and sharp cutting edge allow them to quickly penetrate the ground, positioning the drill bit 45 and providing initial rock breaking, reducing the initial difficulty of the drill bit 45 and improving drilling efficiency.

[0075] The support rod 41 is firmly connected to the inner wall of the storage tube 40, providing stable support for the protective shell 42 and the motor 2 43. During the drilling process, the support rod 41 is subjected to various forces such as the reaction force and vibration generated by the drill bit 45 when drilling. Its high strength and rigidity ensure that the drilling structure remains stable under complex stress conditions, avoiding the impact of shaking or displacement on drilling accuracy and sampling quality. The protective shell 42 provides all-round protection for the motor 2 43. Its sealing structure effectively blocks the entry of impurities such as dust, mud and water, preventing the motor 2 43 from being damaged by external environmental factors. At the same time, the heat dissipation design can promptly dissipate the heat generated by the operation of the generator 2 43, ensuring that the motor 2 43 always operates stably within an appropriate temperature range.

[0076] As the drill bit 45 continues to drill, the crushed rock and soil samples will enter the interior of the storage tube 40. The storage tube 40 is connected to the fixed sleeve 90 via a threaded connection. The fixed sleeve 90 is in turn connected to the extension rod 30. The extension rod 30 can be adjusted in length according to the drilling depth, allowing the storage tube 40 to extend as the drilling depth increases, ensuring sufficient space to accommodate the rock and soil samples. After drilling and sampling are completed, the motor 2 43 is turned off. The operator can remove the storage tube 40 by disassembling the threaded connection between the fixed sleeve 90 and the storage tube 40, and then obtain the rock and soil samples inside for subsequent geological analysis and research.

[0077] Application Examples

[0078] The sampling depth of the mining geological exploration drilling sampling device of the present invention can be flexibly configured according to actual conditions. By utilizing the threaded connection design between the casing 20, the extension rod 30, and the storage tube 40, a maximum drilling sampling depth of 15 meters can be achieved, meeting the needs of most shallow mining geological exploration and general soil survey work. Regarding sampling diameter, the device is adaptable to a variety of drill bits 45, ranging from a minimum diameter of 30mm for fine sampling, suitable for obtaining small-scale, high-precision samples, to a maximum diameter of 150mm for large-diameter sampling, suitable for exploration scenarios requiring large samples for comprehensive analysis.

[0079] In terms of applicable mineral types, for softer minerals such as coal and salt mines, the device can avoid excessive crushing of the sample by adjusting the rotation speed of the motor 2 43 and selecting a suitable drill bit, thereby completely preserving the original structure and composition of the sample. For non-metallic minerals of medium hardness such as limestone and marble, the drive assembly can provide stable torque, and when used with a wear-resistant drill bit, drilling and sampling can be completed. As for metal ores such as copper, iron, and gold, whether they are oxide ores in the surface weathering layer or primary ores at a certain depth underground, the device can adjust the drilling parameters in time according to complex geological conditions by virtue of its equipped torque sensor 15, tilt sensor 80, vibration accelerometer 83 and other real-time monitoring equipment to ensure high-quality sampling results. In addition, in soil survey work, the present invention can obtain soil samples of different depths through a controlled and stable structure, providing reliable data support for soil composition analysis, land quality assessment, and environmental monitoring.
