Description

Technical Field

[0001] This invention relates to the field of mining exploration technology, specifically to a drilling machine for mineral engineering geological exploration. Background Technology

[0002] In the field of mineral engineering geological exploration, most traditional drilling rigs have a one-piece structure, making them bulky and cumbersome. This hinders their mobility and operation in areas with complex terrain and poor accessibility, such as narrow mountain trails, paths in dense forests, and narrow city streets. In areas inaccessible by vehicles, drilling work is often obstructed, severely limiting their applicability. During transportation, the non-disassembled structure and non-foldable drilling rig of traditional drilling rigs result in a large overall size, increasing transportation difficulty and costs.

[0003] Chinese Patent Publication No. CN119466573A discloses a vehicle-mounted underground exploration drilling device and method, comprising a mounting plate, four guide rails, a first hydraulic cylinder, a movable frame, and a drilling mechanism. This vehicle-mounted underground exploration drilling device, by incorporating a mounting plate, guide rails, a first hydraulic cylinder, a movable frame, and a drilling mechanism, and by using the mounting plate and guide rails installed within a vehicle, facilitates the transport of the drilling mechanism to a designated location by vehicle, improving transportation convenience. Furthermore, since the drilling mechanism and the movable frame are detachably connected, when the exploration site is inaccessible by vehicle, the drilling mechanism can be separated from the movable frame and then manually moved to the designated location for drilling operations, enhancing the device's flexibility. While the aforementioned patented device allows for the separate transport of the drilling mechanism, its drilling mechanism is always vertically installed, limiting drilling depth, making it unsuitable for installing long drill rods, and unable to traverse areas with height restrictions, such as dense forests, resulting in poor maneuverability. The above-mentioned equipment has poor overall stability, requires manual handling, and cannot adapt to long-distance and complex road conditions. The mobile frame body has insufficient ground support during drilling, resulting in insufficient overall stability.

[0004] Furthermore, traditional drilling rigs also have shortcomings in terms of operational stability. In areas with complex geological conditions, such as soft soil layers and slopes, drilling rigs are prone to shaking and displacement due to vibration, uneven ground, or other external forces, affecting the accuracy and reliability of drilling work, and consequently leading to drilling accidents and errors, thus reducing drilling quality. Summary of the Invention

[0005] Therefore, it is necessary to provide a drilling machine for mineral engineering geological exploration to address the existing technical problems.

[0006] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows:

[0007] This invention provides a drilling machine for mineral engineering geological exploration, including an exploration vehicle chassis and a detachable frame mounted on the chassis.

[0011] Preferably, a third hydraulic rod is installed on the frame, and the lower frame is divided into two hinged folding frames that are hinged to each other. The third hydraulic rod is hinged at the front end of the frame, and the output end of the third hydraulic rod is connected to the hinge of the two hinged folding frames. When the two hinged folding frames are in the folded state, a first linear guide rail is provided on the opposite side. A second linear guide rail is installed on the upper frame. When the drilling frame is in the unfolded state, the first and second linear guide rails are combined to form a straight guide rail. The lifting frame is vertically slidably connected to the drilling frame through the straight guide rail. A multi-stage telescopic hydraulic cylinder is provided at the top of the upper frame, and the output end of the multi-stage telescopic hydraulic cylinder is fixedly connected to the upper frame.

[0012] Preferably, the frame is also provided with a fourth hydraulic rod, the output end of which is hinged to the top of the support frame. The frame is equipped with a lifting seat that can be raised and lowered, and the fourth hydraulic rod and the support frame are respectively hinged to both ends of the lifting seat.

[0013] Preferably, the mounting frame is equipped with a second lifting plate that can be raised and lowered. The main insertion rod is installed below the second lifting plate. The second lifting plate is equipped with a rotary driver that drives the main insertion rod to rotate. The main insertion rod is hollow inside. A pull rod is coaxially provided inside the main insertion rod. The second lifting plate is equipped with a fifth hydraulic rod. The output end of the fifth hydraulic rod is fixedly connected to the pull rod. The pull rod is connected to several insertion rods in a transmission manner. The main insertion rod is equipped with several guide and limiting holes for the insertion rods to be inserted.

[0014] Preferably, the multiple insertion rods are divided into two groups. One group is set horizontally, while the other group is set inclined upwards from the center of the insertion rod. A ring frame is installed on the pull rod to drive and cooperate with it. The ring frame is provided with multiple horizontal and inclined sliding grooves.

[0016] Preferably, the drilling rig includes a drilling motor, a rotating connecting seat, and a drill rod clamping claw for stabilizing and limiting the drill rod. The drilling motor is mounted on the lifting frame and is connected to the rotating connecting seat. The drill rod clamping claw is mounted on the lifting frame and located directly below the rotating connecting seat.

[0017] The advantages of this invention compared to the prior art are:

[0018] 1. This invention, by setting a detachable frame with narrow, low, and short characteristics and equipped with wheels and a power mechanism, combined with limiting grooves and connecting mechanisms on the chassis, enables the drilling rig to move flexibly and operate in complex environments. This allows the drilling rig to move autonomously to the target location for drilling in areas inaccessible by vehicles, greatly expanding its applicability. It has the ability to flexibly navigate complex road conditions such as narrow mountain paths and dense jungle trails. At the same time, the small turning radius improves maneuverability in limited spaces, thereby increasing work efficiency. The drilling frame, with its articulated folding frame design, combined with telescopic hydraulic cylinders and linear guides, achieves flexible folding and unfolding functions for the drilling frame, as well as precise lifting and guiding functions for the lifting frame. The drilling frame can be folded when not in use, reducing the overall size of the equipment and facilitating transportation; when drilling, it unfolds to provide stable support for the lifting frame and drilling rig.

[0019] 2. The connection mechanism utilizes a first connecting device consisting of a bidirectional lead screw slide, a first hinge rod, a locking block, and a rubber pad, and a second connecting device consisting of a lateral clamping plate, a support rod, a clamping block, and an adjusting telescopic component. This achieves a stable and reliable connection between the frame and the chassis. The first connecting device ensures a firm connection between the frame and the chassis, while the rubber pad increases sealing and friction. The second connecting device provides lateral support to the protruding mounting bracket, enhancing overall connection stability, preventing lateral displacement of the mounting bracket, and ensuring the structural stability of the drilling rig during operation.

[0020] 3. Utilizing the telescopic mechanism connected to the mounting frame within the chassis, along with the main and auxiliary rods within the mounting frame, the mounting frame achieves flexible extension and retraction according to the working environment, while also providing stable ground support for the drilling rig. In complex road conditions, the mounting frame can retract into the chassis, reducing the chassis width and improving the drilling rig's maneuverability and passability. During drilling operations, the mounting frame extends, the main rod rotates and inserts into the ground, and the auxiliary rods expand outwards, significantly increasing the contact area and grip with the soil. This ensures the drilling rig remains stable under various geological conditions, effectively preventing swaying and displacement caused by uneven ground or external forces, thus ensuring the accuracy and reliability of drilling operations. The cooperation of the blocking ring, tie rod, and ring frame on the main rod prevents internal blockage of the main rod and ensures precise movement of the auxiliary rods. The blocking ring seals the guide limit hole during the insertion or withdrawal of the main rod, preventing soil from entering and causing blockage. It also plays a precise control role during the outward expansion and repositioning of the auxiliary rods, ensuring the normal operation of the entire support structure. Attached Figure Description

[0037] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1-14 The drilling rig for mineral engineering geological exploration shown includes an exploration vehicle chassis 1 and a detachable frame 2 mounted on the chassis 1. The frame 2 has wheels 3 at its bottom, and the chassis 1 has limiting grooves 4 for the wheels 3 to travel on. The chassis 1 is connected to the frame 2 via a connecting mechanism 5. A drilling mechanism is mounted on the frame 2, including a drilling frame 6 composed of an upper frame 7 and a lower frame 8, and a lifting frame 9 mounted on the upper frame 7. A drilling rig device for drilling is mounted on the lifting frame 9. 10. The chassis 1 is provided with a clearance passage for the drilling rig 10 to work. The lower frame 8 is a hinged folding frame. The frame 2 is provided with a support frame 11. The upper frame 7 is fixed on the support frame 11. The drilling frame 6 is equipped with a locking device 12 to lock the drilling frame 6 in the folded or unfolded state. The two sides of the frame 2 are provided with extendable mounting frames 13. The mounting frames 13 are provided with a main insertion rod 14 that can be inserted into the soil layer. The main insertion rod 14 is also provided with a number of branch insertion rods 15 that are distributed in a ring and extend outward from the main insertion rod 14.

[0039] In this invention, a detachable frame 2 is provided above the chassis 1, and the drilling mechanism is mounted on the frame 2, enabling the drilling rig to operate efficiently in various complex environments. In areas with complex terrain that are difficult for vehicles to access directly, the frame 2 can be detached and moved to the target location for drilling via its own wheels 3, avoiding work obstruction caused by inaccessibility. Its narrow, low, and short shape allows it to easily handle poor road conditions, enabling it to flexibly traverse narrow mountain paths and trails in dense forests during field exploration, greatly expanding the drilling rig's applicability. The small turning radius further enhances its maneuverability in limited spaces, facilitating adjustments to the drilling position in complex terrain and improving work efficiency. The frame 2 adopts a short wheelbase design, combined with the independent steering structure of the wheels 3, resulting in a smaller turning radius than conventional drilling rigs. When the frame 2 is mounted on the chassis 1, the chassis 1 and the frame 2 are fixedly connected by the connecting mechanism 5. The drilling mechanism can perform drilling work on the frame 2 alone, or it can work on the chassis 1 while connected. The connecting mechanism 5 will not disconnect when working on the chassis 1.

[0040] The articulated folding frame design of the drilling rig 6 and the detachable chassis 2 make the drilling rig more convenient to transport. When not in use, the drilling rig 6 can be folded up to reduce the overall size of the equipment, and the chassis 2 can be moved independently to improve its maneuverability and stability.

[0041] The mounting frame 13 and its main insertion rod 14 can retract into the chassis 2. When locking is required, the mounting frame 13 is moved to the side of the chassis 2, the main insertion rod 14 is rotated and inserted deep into the ground, and then expanded outward through the branch insertion rod 15 to further improve grip. This structure enables multiple locking connection points between the drilling rig and the ground, effectively preventing the drilling rig from shaking or shifting due to vibration, uneven ground, or other external forces during drilling, ensuring the accuracy and reliability of drilling work. Especially in areas with complex geological conditions, such as soft soil layers and slopes, this stable support structure can ensure the normal operation of the drilling equipment, improve drilling quality, and reduce drilling accidents and errors caused by equipment instability. The retraction of the mounting frame 13 can reduce the width of the chassis 2, increasing its passability to adapt to more challenging travel environments. The extended mounting bracket 13 can improve the stability of the fixed position with the ground. When connected to the chassis 1, the extended mounting bracket 13 can be locked from the direction of travel to improve the stability of the vehicle body connection, reduce the occurrence of collisions during driving, and avoid damage to the equipment.

[0042] It is worth mentioning that the front end of the frame 2 shown in this invention is equipped with a power mechanism to provide driving power for movement, avoid manual transfer, and improve traffic capacity.

[0043] The connecting mechanism 5 includes a first connecting device that is mounted on the chassis 1. A locking groove 16 is installed on the side wall of the frame 2. The first connecting device includes a bidirectional screw slide 17, a first hinge rod 18, and a locking block 19. The bidirectional screw slide 17 is arranged in the same direction as the length direction of the chassis 1. There are two first hinge rods 18, which are respectively mounted on two sliding seats of the bidirectional screw slide 17. The locking block 19 is located in the middle of the bidirectional screw slide 17. One end of the first hinge rod 18 is hinged to the sliding seat, and the other end is hinged to the locking block 19. The locking block 19 can be inserted into the locking groove 16. The outside of the locking block 19 is filled with a rubber pad.

[0044] When the drilling rig needs to connect the frame 2 to the chassis 1, the frame 2 is first moved above the chassis 1 so that the locking groove 16 on the frame 2 corresponds to the locking block 19 of the first connecting device on the chassis 1, in preparation for the subsequent locking operation.

[0045] When the frame 2 moves to the locked position of the chassis 1, the first connecting device is activated to lock the frame 2 to the chassis 1. The bidirectional lead screw slide 17 operates, causing the two sliding seats to move towards each other. Through the first hinge rod 18, the locking block 19 is moved horizontally towards the frame 2, inserting the locking block 19 into the locking groove 16 on the side wall of the frame 2, thus realizing the locking connection between the frame 2 and the chassis 1. The rubber pad has a certain elasticity. When the locking block 19 is inserted into the locking groove 16, the rubber pad can fill the gap between the locking block 19 and the locking groove 16, increasing the friction and sealing between them, preventing the locking block 19 from loosening due to vibration or other reasons during the operation of the drilling rig, and ensuring the stability of the connection between the frame 2 and the chassis 1.

[0046] The frame 2 is also equipped with a telescopic mechanism that is connected to the mounting frame 13. The telescopic mechanism includes a first hydraulic rod 20, a second hydraulic rod 21, a horizontal telescopic frame 22, a first lifting plate 23, and a second hinge rod 24. The first hydraulic rod 20 and the second hydraulic rod 21 are both vertically mounted on the frame 2. The output end of the first hydraulic rod 20 is fixedly connected to the first lifting plate 23. One end of the horizontal telescopic frame 22 is fixedly connected to the first lifting plate 23, and the other end of the horizontal telescopic frame 22 is fixedly connected to the mounting frame 13. The two ends of the second hinge rod 24 are respectively hinged to the output end of the second hydraulic rod 21 and the side wall of the mounting frame 13. A horizontal abutment plate 25 that is flush with the bottom of the mounting frame 13 in the retracted state is installed on the frame 2.

[0047] When the frame 2 needs to detach from the chassis 1 and move independently, in order to reduce the width of the frame 2 and increase its passability, the mounting frame 13 needs to be retracted into the frame 2. The first hydraulic rod 20 drives the first lifting plate 23 to rise, and the horizontal telescopic frame 22, which is fixedly connected to the first lifting plate 23, drives the mounting frame 13 to rise synchronously. The second hydraulic rod 21 retracts, causing the second hinge rod 24 to deflect. At this time, the horizontal telescopic frame 22 retracts, and the mounting frame 13 retracts into the frame 2. When the frame 2 is connected to the chassis 1 or when the drilling mechanism is ready to work, the mounting frame 13 needs to extend out of the frame 2. The second hydraulic rod 21 extends and drives the mounting frame 13 outward through the second hinge rod 24. After it is fully extended, the first hydraulic rod 20 and the second hydraulic rod 21 drive synchronously. The second hinge rod 24 and the horizontal telescopic frame 22 descend synchronously, thereby driving the mounting frame 13 to descend smoothly. After reaching the predetermined position, the second hydraulic rod 21 continues to retract, bringing a part of the top of the mounting frame 13 into contact with the horizontal abutment plate 25, so that the frame 2 and the mounting frame 13 provide vertical support. The design of the telescopic mechanism allows the mounting frame 13 to extend and retract flexibly according to actual working needs. When the frame 2 needs to move on its own in complex road conditions, the mounting frame 13 can retract into the frame 2, reducing the overall width of the frame 2, allowing the frame 2 to pass smoothly through narrow passages or areas with limited space, greatly improving the maneuverability and passability of the drilling rig. During drilling operations, the mounting frame 13 extends beyond the chassis 2 and connects to the ground via the main insertion rod 14 and the branch insertion rod 15, providing stable support for the drilling rig and ensuring the smooth progress of drilling work. This function, which allows for flexible adjustment of the mounting frame 13's state in different working scenarios, enhances the drilling rig's adaptability to various working environments and improves the equipment's practicality.

[0048] The connecting mechanism 5 also includes a second connecting device, which includes a lateral abutment plate 26 hinged to the bottom of the chassis 1. The outer side wall of the lateral abutment plate 26 is in contact with the side wall of the extended mounting bracket 13, and the contact surface is the front or rear end of the chassis 1. A support rod 27 hinged to the chassis 1 is also provided between the lateral abutment plate 26 and the chassis 1. A abutment block 28 that is in contact with the lateral abutment plate 26 is installed on the top of the support rod 27. An adjusting telescopic component 29 is provided in the middle of the support rod 27.

[0049] After the frame 2 is connected to the chassis 1 and the mounting bracket 13 extends, the second connection device needs to be activated to further enhance the connection stability. At this time, the lateral abutment plate 26 rotates around its hinge point with the bottom of the chassis 1 until it rotates to a vertical position and tightly abuts against the side wall of the extended mounting bracket 13. After the lateral abutment plate 26 rotates into place, the support rod 27 is lifted upward through its hinge point with the chassis 1, so that the top abutment block 28 fits against one side of the top edge of the lateral abutment plate 26. Subsequently, the telescopic adjustment component 29 starts to work, changing the support angle and force of the support rod 27 by adjusting its own length, thereby precisely adjusting the abutment support force on the lateral abutment plate 26 to ensure that the lateral abutment plate 26 can stably provide lateral support to the mounting bracket 13.

[0050] A third hydraulic rod 30 is installed on the frame 2. The lower frame 8 is divided into two hinged folding frames that are hinged to each other. The third hydraulic rod 30 is hinged at the front end of the frame 2. The output end of the third hydraulic rod 30 is connected to the hinge of the two hinged folding frames. When the two hinged folding frames are in the folded state, a first linear guide rail 31 is provided on the opposite side. A second linear guide rail 32 is installed on the upper frame 7. When the drilling frame 6 is in the unfolded state, the first linear guide rail 31 and the second linear guide rail 32 are combined to form a whole straight guide rail. The lifting frame 9 is vertically slidably connected to the drilling frame 6 through the straight guide rail. A multi-stage telescopic hydraulic cylinder 33 is provided at the top of the upper frame 7. The output end of the multi-stage telescopic hydraulic cylinder 33 is fixedly connected to the upper frame 7.

[0051] When the drilling rig 6 needs to be deployed, the third hydraulic rod 30 pushes the two hinged folding frames to rotate around their hinge point. The two hinged folding frames gradually rotate from a folded state to a vertical state. During this process, the upper frame 7, connected to the upper hinged folding frame, is also simultaneously lifted upwards. When the two hinged folding frames are fully vertical, the first linear guide rail 31 installed on their opposite sides and the second linear guide rail 32 on the upper frame 7 fit together perfectly, forming a complete straight guide rail. At this time, the lifting frame 9 achieves a vertical sliding connection with the drilling rig 6 through this straight guide rail. Immediately afterwards, the multi-stage telescopic hydraulic cylinder 33 at the top of the upper frame 7 is activated, its output end extending or retracting, driving the lifting frame 9 to move up and down along the straight guide rail to meet drilling needs at different depths. When drilling work is completed or when the drilling rig needs to be transported, the drilling rig 6 needs to be folded up. At this point, the multi-stage telescopic hydraulic cylinder 33 moves the lifting frame 9 to a suitable position, and then the third hydraulic rod 30 reverses its action, pulling the two hinged folding frames to flip around the hinge point into a folded state. As the third hydraulic rod 30 pulls, the upper frame 7 gradually descends, the first linear guide rail 31 and the second linear guide rail 32 separate, and finally the two hinged folding frames return to the folded state, reducing the space occupied by the drilling frame 6 and facilitating transportation and storage.

[0052] The frame 2 is also equipped with a fourth hydraulic rod 34. The output end of the fourth hydraulic rod 34 is hinged to the top of the support frame 11. The frame is equipped with a lifting seat 51 that can be raised and lowered. The fourth hydraulic rod 34 and the support frame 11 are respectively hinged to the two ends of the lifting seat 51.

[0053] The fourth hydraulic rod 34 enables the folding function of the support frame 11, which in turn drives the connected upper frame 7 to flip and fold synchronously, further reducing the height and enhancing passability and driving stability. During the process of unfolding the articulated folding frame into a vertical state, the lifting seat 51 rises accordingly, driving the support frame 11 to move and keeping the support frame 11 in a vertical state at all times.

[0054] The mounting bracket 13 has a second lifting plate 35 that can be raised and lowered. The main insertion rod 14 is installed below the second lifting plate 35. The second lifting plate 35 has a rotary driver 36 that drives the main insertion rod 14 to rotate. The main insertion rod 14 is hollow inside. A pull rod 37 is coaxially installed inside the main insertion rod 14. The second lifting plate 35 has a fifth hydraulic rod 38. The output end of the fifth hydraulic rod 38 is fixedly connected to the pull rod 37. The pull rod 37 is connected to several insertion rods 15. The main insertion rod 14 has several guide limiting holes 39 for the insertion of the insertion rods 15.

[0055] When the chassis 2 needs to be stably supported on the ground, the rotary drive 36 drives the main insertion rod 14 to rotate. The second lifting plate 35 descends, causing the main insertion rod 14 mounted on it to descend as well, inserting it into the soil layer for fixation. After insertion, the fifth hydraulic rod 38 on the second lifting plate 35 pulls the tie rod 37 upward, causing several branch insertion rods 15 to expand outward from the guide limiting holes 39. This method achieves efficient and stable support for the chassis 2 on the ground. The main insertion rod 14, by rotating and inserting into the soil, can quickly and firmly fix the position of the chassis 2, providing a foundation for the subsequent expansion of the branch insertion rods 15. The branch insertion rods 15 expand outward from the main insertion rod 14, greatly increasing the contact area and gripping force with the soil, enabling the drilling rig to remain stable under various geological conditions. This effectively avoids shaking and displacement caused by uneven ground or external forces, ensuring smooth drilling operations.

[0056] Several insertion rods 15 are divided into two groups. One group is set horizontally, while the other group is set gradually upward from the center of the insertion rod 14. A ring frame 40 is installed on the pull rod 37 to drive and cooperate with it. The ring frame 40 is provided with several horizontal sliding grooves 41 and inclined sliding grooves 42. The ends of the inclined insertion rods 15 are slidably set in the horizontal sliding grooves 41, and the ends of the horizontal insertion rods 15 are slidably set in the inclined sliding grooves 42.

[0057] When the insert rod 15 needs to be inserted into the soil, the pull rod 37 moves upward, causing the ring frame 40 connected to it to move upward. At the same time, the end of the inclined insert rod 15 moves outward along the horizontal slide 41, thus inserting into the soil through the inclined guide limiting hole 39. The end of the horizontal insert rod 15 moves outward along the inclined slide 42, and inserts into the soil through the horizontal guide limiting hole 39 while maintaining a constant horizontal height.

[0058] Two sets of branch rods 15, arranged in different directions, can support and reinforce the main branch rod 14 from multiple angles. The horizontally arranged branch rods 15 increase the horizontal pull-out resistance, preventing the drilling rig from shifting when subjected to horizontal external forces (such as wind force, horizontal forces generated by ground vibration, etc.). The inclined branch rods 15 enhance the oblique pull-out resistance, improving the stability of the drilling rig under different terrain and geological conditions, enabling the drilling rig to remain firmly fixed even in complex environments such as soft soil and slopes, effectively improving the stability and reliability of drilling operations.

[0059] The main insertion rod 14 has an annular mounting groove, and a blocking ring 43 with a closed guide limiting hole 39 is slidably disposed in the annular mounting groove. A transmission ring 44 is slidably mounted on the pull rod 37. The transmission ring 44 is fixedly connected to the blocking ring 43 through a transmission frame 45. A spring 46 is provided between the transmission ring 44 and the bottom of the pull rod 37. The two ends of the spring 46 are fixedly connected to the bottom of the transmission ring 44 and the bottom of the pull rod 37, respectively. The pull rod 37 is also provided with a limiting ring 47 that can abut against the ring frame 40.

[0060] The blocking ring 43 is used to block the guide limiting hole 39. This function is used during the insertion or removal of the main insertion rod 14. When the main insertion rod 14 is in either of these two states, it can close the guide limiting hole 39 to prevent soil from entering the main insertion rod 14 through the guide limiting hole 39 and causing internal blockage. After the main insertion rod 14 is inserted into place, the pull rod 37 can drive the blocking ring 43 to move upward. The pull rod 37 has two strokes. When the blocking ring 43 is closed, the pull rod 37 is in the lowest position. The bottom of the pull rod 37 is connected to the blocking ring 43 through the transmission ring 44 and the transmission frame 45. When it is necessary to expand outward, the blocking ring 43 needs to be opened upward first. The pull rod 37 rises and the blocking ring 43 rises synchronously with the pull rod 37 through the transmission ring 44 and the transmission frame 45. At this time, the ring frame 40 does not move, and the pull rod 37 slides relative to the ring frame 40. During this stroke, only the blocking ring 43 moves upward into place. After the blocking ring 43 moves into position within the annular mounting groove, the pull rod 37 performs its second stroke. The limiting ring 47 fixed on the pull rod 37 abuts against the ring frame 40, causing the ring frame 40 to move upward synchronously. At this time, the insertion rod 15 is displaced, and the blocking ring 43 does not move when the spring 46 compresses the insertion rod 15. During the reset, the pull rod 37 descends, the insertion rod 15 resets, and the spring 46 recovers. As it continues to descend, the spring 46 drives the transmission ring 44 to move, which in turn drives the blocking ring 43 to reset via the transmission frame 45.

[0061] The drilling rig 10 includes a drilling motor 48, a rotating connecting seat 49, and a drill rod clamping claw 50 for stabilizing and limiting the drill rod. The drilling motor 48 is mounted on the lifting frame 9 and is connected to the rotating connecting seat 49 in a transmission manner. The drill rod clamping claw 50 is mounted on the lifting frame 9 and is located directly below the rotating connecting seat 49.

[0062] Before drilling operations, select a suitable drill rod length (long or short) based on the different folding states of the drilling frame 6 and the actual drilling requirements. Install the selected drill rod between the rotating connecting seat 49 and the drill rod clamping jaws 50, ensuring a secure installation. The drilling motor 48 drives the drill rod connected to it to rotate at high speed via the rotating connecting seat 49. During the rotation of the drill rod, the drill rod clamping jaws 50 provide stable support and limit the drill rod, preventing it from shaking, shifting, or falling off during high-speed rotation. As the lifting frame 9 slides up and down on the drilling frame 6, the drill rod can penetrate to different depths underground to obtain geological samples or conduct related geological exploration work.

[0063] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
