Description

Technical Field

[0001] The invention relates to a drilling device for geological prospecting, belonging to the technical field of geological exploration. Background Art

[0002] With the rapid development of new energy vehicles and energy storage systems, demand for energy metals will continue to grow. New energy battery metal materials primarily include lithium, cobalt, nickel, manganese, and chromium. These metals play a key role in the production, storage, and transmission of energy. They are core components of lithium battery cathode materials (such as ternary materials and lithium iron phosphate), directly impacting battery energy density and safety. Currently, lithium, cobalt, nickel, and manganese are primarily sourced from ores or associated minerals. Lithium resources are primarily extracted from lithium ores (such as spodumene and lepidolite) and salt lake brine. Cobalt occurs primarily as an associated mineral in sulfide deposits of copper, nickel, and iron, requiring extraction through ore smelting. Nickel resources primarily consist of nickel sulfide ores and laterite nickel ores, requiring ore processing. Manganese resources primarily rely on the mining of manganese ores, including manganese carbonate and manganese oxide. Geological prospecting is a core prerequisite for the sustainable development of the lithium, cobalt, nickel, and manganese extraction industries from ores of lithium, cobalt, nickel, and manganese.

[0003] Lithium, cobalt, nickel, and manganese are core raw materials for modern industry, particularly in new energy and high-end manufacturing. Their supply is highly dependent on the development of ores and associated minerals. Strengthening mineralization theory research, technological innovation, and strategic resource reserves can significantly enhance resource self-sufficiency and support high-quality economic development.

[0004] Geological prospecting requires drilling equipment, a core tool used throughout the entire process, from sample collection to resource evaluation. Technological advancements directly impact the exploration efficiency and development safety of scarce minerals such as lithium, cobalt, and nickel. Existing drilling equipment is typically fixed and placed directly on the ground, resulting in relatively poor stability, poor adaptability to complex operating environments, and inconvenient installation and adjustment. Once positioned at the site to be drilled, the equipment can easily shift during operation, making it inconvenient to use and insufficiently adaptable to complex geological conditions. During drilling, the high-speed rotation of the drill bit and drive shaft can easily cause debris to fly (e.g., knocking rocks or soil off the outside of the drill bit or the spiral drive shaft). This can strike nearby personnel, causing unnecessary injuries or soiling, resulting in a poor user experience. Furthermore, automated drilling rigs require specialized personnel, sometimes multiple people simultaneously, to operate. Improper operation can easily lead to reduced efficiency or equipment failure. Equipment maintenance relies on specialized technical teams, resulting in high maintenance costs and long response times in remote areas. Operation is complex and difficult. Summary of the Invention

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0031] Example 1

[0032] like Figure 1 and 2As shown, a drilling device for geological prospecting includes a drilling mechanism with a rotary drilling function. The drilling mechanism includes a drill rod 1 capable of performing a cutting action and a drive motor 2 that provides rotational power to the rod-shaped drill. The output end of the drive motor 2 is mechanically connected to the end of the drill rod 1, driving the drill rod 1 to rotate to perform drilling operations at a target location. The device also includes a support frame for supporting the drilling mechanism and a drive mechanism. The drilling mechanism is mounted on the support frame and slidably connected thereto. The drilling mechanism is vertically mounted on the frame-type support structure via sliding fittings. The drive mechanism is mounted on the support frame and connected to the drilling mechanism, and the drive mechanism can be controlled to slide the drilling mechanism up and down. When drilling during geological drilling operations, the support frame is first stably placed on a predetermined drilling location surface. The drive mechanism controls the drilling mechanism to slide up and down along the support frame. As the drilling mechanism slides downward along the support frame, the target location is drilled. In this embodiment, the drilling mechanism can also transmit the rotational power of the drive motor 2 directly to the drill rod 1 via a rigid coupling, creating an efficient torque transmission path. Carbide cutting teeth can also be installed at the end of the drill rod 1, creating a composite drilling action during the rotational downward pressure process, combining impact crushing and cutting and stripping functions to adapt to rock formations of varying hardness. Furthermore, the support frame can also feature a quick-disassembly interface.

[0033] In this embodiment, the mechanical connection between the drive motor 2 and the drill rod 1 is used to provide high-torque rotational power for the drill tool, thereby realizing the cutting and crushing function of geological structures such as rock strata and soil, and adapting to geological conditions of different hardness. The drilling mechanism is connected to the support frame through sliding fitting components, and the drive mechanism can accurately adjust the vertical displacement of the drill rod 1 to ensure that the drill tool always moves in a preset vertical direction during the drilling process to avoid drilling deviation. As the basic structure of the equipment, the support frame provides a stable bearing platform through rigid materials (such as steel structures) and ground fixing devices, effectively dispersing the vibration and reaction force generated by the drilling operation to prevent the equipment from overturning. The drive mechanism (such as a hydraulic cylinder, a gear rack or a motor screw) can realize the automatic lifting and lowering control of the drilling mechanism, reduce manual intervention, and adapt to the needs of continuous drilling or layered sampling.

[0034] This embodiment reduces operational difficulty, reduces labor input, and improves operational efficiency. It also ensures stable drilling, facilitating the smooth and orderly conduct of prospecting operations and enabling efficient and precise drilling. Sliding fittings constrain the motion trajectory of the drill rod 1, significantly reducing the risk of borehole deviation, improving the accuracy of geological data acquisition, and achieving high operational precision. The drive mechanism adjusts the downward pressure of the drill rod 1 in real time, preventing drill bit wear or sticking caused by uneven drilling pressure, and providing precise pressure control. The fixed mounting of the support frame allows for rapid repositioning of the equipment in the same position, making it suitable for multi-point drilling or stratified sampling. The drive motor 2 is directly connected to the drill rod 1, reducing transmission losses, improving energy efficiency, and shortening single-hole drilling time. The frame-type support structure absorbs drilling vibrations through rigid connections, extending the service life of key components such as the motor and bearings. The modular design facilitates disassembly and transportation, making it suitable for complex field terrain. The frame structure can be expanded with additional devices (such as a mud circulation system) and is compatible with a variety of drilling processes. The drive mechanism can be integrated with an automated control system for remote operation, reducing the risk of personnel exposure to high-pressure and dusty environments.

[0035] It can be understood that this embodiment is not only applicable to core sampling in mineral exploration, but is also applicable to soil layer analysis in engineering geological surveys, rapid drilling of environmental monitoring wells, and deployment of deep monitoring points for geological disaster warnings.

[0036] Example 2

[0037] This embodiment further optimizes the supporting frame structure based on the embodiment 1, specifically:

[0038] The support frame includes a vertical frame 3 and a bottom frame 4 arranged at the bottom of the vertical frame 3, and the two are respectively assembled by welding rectangular tubes. Two guide rods 5 are arranged in parallel on the vertical frame 3, and a mounting seat 6 is provided on the drilling mechanism. A guide cylinder 7 corresponding to the guide rod 5 is provided on the mounting seat 6. The guide cylinder 7 is slidably connected to the guide rod 5. Specifically, the guide rod 5 is inserted into the guide cylinder 7, thereby realizing the sliding connection between the drilling mechanism and the support frame.

[0039] Example 3

[0040] This embodiment further optimizes the driving mechanism structure based on the embodiment 2, specifically:

[0041] The drive mechanism includes a screw 8 and a nut holder 9. The nut holder 9 is mounted on the mounting base 6. The screw 8 is mounted on the vertical frame 3 and positioned between the two guide rods 5. The screw 8 is threadedly connected to the nut holder 9. Rotation of the screw 8 drives the drilling mechanism to slide. The threaded engagement between the screw 8 and the nut holder 9 converts rotational motion into linear motion, enabling precise vertical lifting and lowering control of the drilling mechanism. The rigid structure of the screw 8 can withstand the high axial loads during drilling operations, ensuring stability during the lifting process.

[0042] The drive mechanism also includes a drive gear 10 and a drive rod 11. Two support plates 12 are mounted on the vertical frame 3, and the drive rod 11 is rotatably mounted between the two support plates 12. A drive gear 10 is provided at the upper end of the drive rod 11 and the upper end of the screw rod 8, respectively. The two drive gears 10 are engaged in a transmission, and the screw rod 8 is driven by rotating the drive rod 11. The drive rod 11 engages with the drive gear 10 at the upper end of the screw rod 8 to achieve efficient power transmission from the drive rod 11 to the screw rod 8. The gear meshing design can prevent transmission slippage, improve power transmission efficiency, and reduce mechanical wear.

[0043] The driving mechanism also includes a transmission bevel gear 13, a transmission rod 14 and a turntable 15. The transmission rod 14 is installed on the support plate 12 on the lower side. A transmission bevel gear 13 is installed at the lower end of the drive rod 11 and the end of the transmission rod 14 close to the drive rod 11, respectively. The two transmission bevel gears 13 are meshed with each other. A turntable 15 is fixedly provided at the end of the transmission rod 14 away from the drive rod 11. An operating rod 16 is provided on the turntable 15. A plurality of operating rods 16 are arranged in an array along the turntable 15. The transmission rod 14 meshes with the bevel gear at the end of the drive rod 11 to convert the horizontal axial rotation of the transmission rod 14 into the vertical axial rotation of the drive rod 11, thereby achieving flexible adjustment of the operating direction. The right-angle transmission characteristics of the bevel gear simplify the spatial layout of the equipment. The multiple operating rods 16 distributed in an array on the turntable 15 provide a lever-type manual operation interface. The operator can indirectly control the movement of the screw 8 by rotating the turntable 15 to meet the needs of fine adjustment.

[0044] The screw rod 8 transmission mechanism of this embodiment eliminates the gap error of traditional chain / hydraulic lifting through the continuous contact of the threaded pair, and the vertical displacement accuracy can reach the millimeter level. The parallel layout of the double guide rods 5 and the screw rod 8 (located between the two guide rods 5) forms a three-point support structure, which effectively suppresses the mechanism offset caused by drilling vibration. The gear meshing transmission ratio is constant, and uniform lifting and lowering can be achieved in conjunction with the servo motor or manual operation, avoiding rate fluctuations caused by changes in oil temperature in the hydraulic system. The transmission loss of the bevel gear is lower than that of the belt or worm gear structure, and the transmission efficiency is improved. The multi-operating lever 16 design of the turntable 15 facilitates multi-angle operation and is convenient for control by personnel at different positions.

[0045] Example 4

[0046] This embodiment further optimizes the supporting frame structure based on the third embodiment, specifically:

[0047] The support frame also includes fixed diagonal braces 17 and adjustable diagonal braces 18. Two fixed diagonal braces 17 are provided between the vertical frame 3 and the bottom frame 4 to increase the support stability between the two and improve the bottom stability of the entire support frame. The adjustable diagonal brace 18 is provided on the vertical frame 3 on the opposite side of the fixed diagonal brace 17. The adjustable diagonal brace 18 is hinged to the vertical frame 3 (conventional technical means can be used) to achieve angle adjustment of the adjustable diagonal brace 18, which is convenient for fixing the support frame in different construction environments. The adjustable diagonal brace 18 includes an adjustable sleeve 19 and an adjustable column foot 20, which are threadedly connected, so that the length of the adjustable diagonal brace 18 is adjustable. By providing the adjustable diagonal brace 18 with adjustable angle and length, the support frame is more adaptable to complex field prospecting working environments.

[0048] Example 5

[0049] This embodiment further optimizes the supporting frame structure based on the fourth embodiment, specifically:

[0050] The support frame also includes a drilling guide mechanism, which is arranged on the bottom frame 4 and includes a bottom plate 21 and a guide tube 22 installed on the bottom plate 21. The guide tube 22 passes through the bottom plate 21, and the drill rod 1 extends into the target location along the guide tube 22 to drill a hole.

[0051] In this embodiment, a bottom plate 21 is provided at each end of the guide tube 22 . The bottom plates 21 are fixed to the upper and lower sides of the bottom frame 4 , respectively, to increase the structural strength of the drilling guide mechanism.

[0052] The guide tube 22 passes through the base plate 21 and is installed perpendicular to the ground, providing a rigid motion track for the drill rod 1, forcibly constraining the drilling direction of the drill rod 1, eliminating the problem of drilling inclination caused by uneven geological hardness or drill bit deviation, and ensuring that the verticality error of the drilling is small. The guide tube 22 has a clearance fit with the drill rod 1 (usually 0.5-1mm), which allows the drill rod 1 to rotate at high speed and suppresses the lateral vibration of the drill rod 1 through the friction damping of the pipe wall, reducing the probability of abnormal wear of the drill bit and extending the service life of the drill rod 1. The base plate 21 is fixed to the bottom frame 4 by bolts or clips and can be quickly disassembled and assembled. The integrated design of the base plate 21 and the guide tube 22 reduces the use of independent guide brackets and reduces the complexity of the equipment. At the same time, the rigid connection through the bottom frame 4 enhances the overall torsion resistance, making it suitable for operations in rugged terrain. Forced vertical guidance avoids core sampling distortion or data acquisition errors caused by drilling deviation, and is particularly suitable for mineral exploration scenarios that require high-precision stratigraphic analysis. The contact surface between the bottom frame 4 and the ground is designed with anti-slip grooves or anchoring interfaces to enhance the stability of the equipment on slopes or soft ground.

[0053] Example 6

[0054] This embodiment further optimizes the structure of the mounting base 6 on the basis of embodiment 5, specifically:

[0055] like Figure 3 As shown, the mounting seat 6 includes an L-shaped plate 23 (or a C-shaped plate) and reinforcement strips 24 arranged at the upper and lower ends of one side thereof, which enhance the structural strength and bearing capacity of the mounting seat 6 and facilitate the installation of the drive motor 2. The guide cylinders 7 are respectively arranged at both ends of the reinforcement strip 24, and the nut seat 9 is arranged on the reinforcement strip 24 between the two guide cylinders 7 to ensure stable transmission.

[0056] In this embodiment, a mud guard 25 is provided in the space between the fixed diagonal support 17 and the bottom frame 4 and the vertical frame 3 on the side where the turntable 15 is located to prevent splashing of soil and stones during drilling and affecting the construction of workers.

[0057] Operation and use process: First place the drilling equipment at the target location, make the bottom frame 4 fit the ground as closely as possible, open and adjust the adjustable diagonal brace 18, and ensure the stability of the support frame. Turn on the drive motor 2 to rotate the drill rod 1 at high speed, and at the same time slowly turn the turntable 15 to drive the screw 8 downward, slide along the guide rod 5 through the guide cylinder 7, control the drilling mechanism to move downward at a uniform speed, and the drill rod 1 cuts into the formation along the guide tube 22. Monitor the drilling depth in real time; when encountering hard rock formations, the downward pressure can be increased through the turntable 15, and the rotation speed is reduced for loose formations to prevent hole collapse. After drilling is completed, reverse the turntable 15 to drive the screw 8 upward, lift the drilling mechanism to the initial position, turn off the drive motor 2, clean the rock chips in the drill rod 1 and the guide tube 22, and transport them to the next work point.

[0058] In addition, in the description of the invention, unless otherwise specified, the terms "multiple", "multiple roots", and "multiple groups" are used to mean two or more, and "several", "several roots", and "several groups" are used to mean one or more. In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only used to facilitate the description of the present invention and simplify the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.
