Description

Technical Field

[0001] This invention relates to the field of low-carbon mining technology, specifically to an electrified low-carbon directional drilling device and method. Background Technology

[0002] With the global energy structure transformation and the advancement of the "dual carbon" strategic goals, the traditional fossil energy extraction industry faces the dual pressures of energy conservation and emission reduction, as well as improving quality and efficiency. In the field of mineral resource development, drilling operations, as a key link in obtaining underground resources, have their technological equipment's energy consumption level and environmental performance directly affecting the economics and sustainability of the entire extraction process.

[0003] Current drilling technologies primarily rely on diesel generator sets or hydraulic drive systems for power, but these power sources have several limitations. First, fuel combustion produces large amounts of greenhouse gases and harmful emissions, contradicting current low-carbon development policies. Second, hydraulic transmission systems involve numerous energy transfer stages, resulting in significant efficiency losses and posing a risk of oil leaks that pollute soil and groundwater. Furthermore, traditional drilling rigs often employ a single rotary cutting method for rock breaking, which leads to a sharp drop in drilling efficiency when encountering hard rock formations, resulting in longer work cycles and increased cumulative energy consumption.

[0004] In terms of drilling technology, conventional drilling equipment usually requires frequent drilling and pipe extension to extend the drill string. This intermittent operation mode not only causes repeated interruptions in the drilling process, but also generates additional energy consumption and mechanical wear due to the repeated disassembly and assembly of the drill string.

[0005] For directional drilling, traditional technologies mainly rely on mud motors or screw drills to control the wellbore trajectory. These devices depend on drilling fluid flow and pressure for driving, have low energy conversion efficiency, and have stringent requirements for mud performance, which increases the cost and environmental burden of drilling fluid preparation and treatment.

[0006] The application of electrification technology in the field of engineering machinery is becoming increasingly widespread. Advances in permanent magnet synchronous motors, variable frequency control technology, and energy storage technology have provided a technological foundation for the electrification transformation of drilling equipment. However, existing electric drilling solutions are mostly limited to the simple replacement of surface power units, failing to achieve deep coupling between drilling processes and electric drive systems. There are still some shortcomings in terms of improving rock breaking efficiency, energy recovery and utilization, and continuous automated operation. Summary of the Invention

[0007] The purpose of this invention is to provide an electrified, low-carbon directional drilling apparatus and method to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: An electrified, low-carbon directional drilling apparatus, comprising: The base is used to support and stabilize the entire device at the mining face; The slide is mounted on the base via a lifting mechanism, which can drive the slide to adjust its height in the vertical direction to adapt to different drilling depth requirements. A rotating shaft is vertically mounted on the slide, and a drive mechanism is provided on the slide. The drive mechanism is connected to the rotating shaft and is used to drive the rotating shaft to rotate around its axis. The reciprocating extension mechanism cooperates with the rotating shaft and the driving mechanism respectively. During the process of the driving mechanism driving the rotating shaft to rotate, the reciprocating extension mechanism will drive the rotating shaft to slide vertically back and forth, and the downward stroke of the rotating shaft will increase successively to achieve continuous downward drilling.

The collar is rotatably mounted on the horizontal plate, and the rotating shaft is rotatably mounted on the carriage.

[0012] The directional drilling rig for electrified, low-carbon mining as described above: The rotating shaft and the collar are slidably coupled coaxially. The outer wall of the rotating shaft is provided with a protrusion along its length direction, and the inner wall of the collar is provided with a groove along its length direction. The protrusion is slidably fitted into the groove. One end of the rotating shaft is coaxially provided with a driving sprocket, and the outer wall of the collar is coaxially provided with a driven sprocket. The driving sprocket and the driven sprocket are connected by a chain.

[0013] The directional drilling rig for electrified, low-carbon mining as described above: The drive mechanism also includes a geared motor and a rotating drum. The geared motor is mounted on the slide, and the rotating drum is vertically rotatably mounted on the slide. The output end of the geared motor is coaxially connected to the rotating drum. The outer wall of the rotating drum is coaxially provided with a driving gear, the outer wall of the rotating shaft is coaxially provided with a driven gear, and the slide is rotatably provided with transmission gears that mesh with the driving gear and the driven gear respectively.

[0014] The directional drilling rig for electrified, low-carbon mining as described above: The reciprocating extension mechanism includes a slide plate, a rotating rod, and a collar. The slide plate is vertically slidably mounted on the slide frame, the collar is mounted on the slide plate, the rotating rod is rotatably engaged with the collar, and the top of the rotating rod is inserted into the rotating cylinder and slidably engaged with it. The outer wall of the rotating rod is provided with a limiting post along its length, and the inner wall of the rotating cylinder is provided with a limiting groove along its length, with the limiting post slidingly fitted into the limiting groove.

[0015] The directional drilling rig for electrified, low-carbon mining as described above: The reciprocating extension mechanism further includes a threaded rod, a threaded sleeve, and a square block. The top of the threaded rod is connected to the bottom of the rotating rod. The threaded sleeve is slidably engaged with the square block, and the square block is mounted on the slide via a bracket. The bottom of the threaded rod is inserted into the threaded sleeve and threadedly engaged with it. The outer wall of the threaded sleeve is provided with a pin along its length, and the inner wall of the square block is provided with a pin groove along its length, and the pin is slidably fitted into the pin groove.

[0016] The directional drilling rig for electrified, low-carbon mining as described above: The bottom of the threaded sleeve is provided with a coupling, and the top of the rotating shaft is rotatably connected to the coupling. The slide plate is provided with a ring seat, which is slidably sleeved on the outer wall of the rotating shaft. The outer wall of the rotating shaft is provided with an annular track groove along its length. A steel ball is rolled and embedded in the inner wall of the ring seat, and the steel ball is also rolled and embedded in the annular track groove.

[0017] A method for a directional drilling apparatus suitable for the above-described electrified low-carbon mining, characterized by comprising the following steps: Step 1: Positioning and initial height adjustment of the device. Fix the base to the mining face, start the cylinder, and drive the slide to move vertically along the guide rail according to the target drilling depth requirements. Adjust the slide to the appropriate working height position to complete the initial configuration of the device. Step 2: Rotary power transmission and shaft rotation drive. Start the geared motor, and the drum rotates under the drive of the geared motor. Through the sequential meshing of the drive gear, transmission gear and driven gear, the rotating shaft and its drive sprocket rotate. The drive sprocket drives the driven sprocket and collar to rotate through the chain. The collar drives the rotating shaft to rotate continuously around its axis through the engagement of the protrusion and groove, providing circumferential cutting power for the drill bit. Step 3: Reciprocating extension motion and incremental drilling. During the rotation of the rotating shaft, the annular track groove applies a periodically changing vertical force to the ring seat through steel balls, driving the slide plate and collar to reciprocate in the vertical direction. The collar drives the rotating rod and threaded rod to reciprocate synchronously. The rotating rod continues to rotate with the rotating drum under the interlocking action of the limiting post and the limiting groove. The rotational motion of the threaded rod is converted into the vertical linear motion of the threaded sleeve under the rotation restriction of the square block on the threaded sleeve. The threaded sleeve drives the rotating shaft to rotate and slide vertically reciprocally through the coupling. The continuous rotation of the threaded rod during the reciprocating motion causes the stroke of the threaded sleeve to increase progressively with each downward movement, thereby realizing the continuous downward drilling of the drill bit driven by the rotating shaft. Step 4: Adaptive adjustment and cyclic operation of drilling depth. As the drilling depth increases, when the slide position deviates from the appropriate working height range, the cylinder is restarted to adaptively adjust the slide height, so that the slide returns to the appropriate position. At the same time, the drill bit continues to perform rotary cutting and axial impact rock breaking operations under the drive of the shaft. Steps 2 to 4 are repeated until the directional drilling operation at the target depth is completed.

[0018] Compared with the prior art, the beneficial effects of the present invention are: The reciprocating extension mechanism couples the rotational motion of the shaft with the vertical reciprocating sliding motion, enabling the drill bit to achieve impact-type downward penetration while rotating and cutting. The rock breaking method changes from simple cutting to a combination of cutting and impact, which improves the drilling speed in hard rock formations. At the same time, the design of progressively increasing downward stroke ensures the continuous accumulation of drilling depth, avoids the interruption of traditional intermittent drill bit lifting and rod connection operations, and shortens the drilling operation time. The integrated design of rotary drive and reciprocating impact reduces the configuration requirements of independent impact equipment, simplifies the power transmission process, and reduces power loss. The adaptive adjustment of the lifting mechanism to the height of the carriage ensures that the drive mechanism always stays in a reasonable working position, reducing the additional torque caused by drill pipe extension and the power transmission loss over long distances, thus optimizing the overall energy utilization rate. Electrification replaces traditional diesel power, eliminating carbon emissions and exhaust pollution from fuel combustion at the source. Improved drilling efficiency shortens the single-well operation cycle, indirectly reducing energy consumption and emissions per unit footage. Optimized energy utilization efficiency further reduces electricity consumption, demonstrating the advantages of low-carbon mining. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Please see Figure 1-11 As one embodiment of the present invention, a directional drilling apparatus for electrified low-carbon mining includes: Base 1, used to support and stabilize the entire device at the mining face; The slide 2 is mounted on the base 1 via a lifting mechanism. The lifting mechanism can drive the slide 2 to adjust its height in the vertical direction to adapt to different drilling depth requirements. A rotating shaft 3 is vertically mounted on the slide 2. The slide 2 is equipped with a driving mechanism, which is connected to the rotating shaft 3 for driving the rotating shaft 3 to rotate around its axis. The reciprocating extension mechanism cooperates with the rotating shaft 3 and the driving mechanism respectively. During the process of the driving mechanism driving the rotating shaft 3 to rotate, the reciprocating extension mechanism will drive the rotating shaft 3 to slide vertically back and forth, and the downward stroke of the rotating shaft 3 will increase step by step to achieve continuous downward drilling. Drill bit 4, which is detachably mounted on the lower end of the rotating shaft 3, is used to perform cutting and rock breaking operations.

[0033] In this embodiment, the base 1 serves as the basic support unit of the entire device, fixed to the mining face and providing stable support for the upper structure. The slide 2 is installed on the base 1 through a lifting mechanism. The lifting mechanism drives the slide 2 to rise and fall in the vertical direction according to the change in drilling depth, so that the slide 2 is always kept at a suitable working height position. The rotating shaft 3 is vertically mounted on the slide 2. The drive mechanism on the slide 2 is connected to the rotating shaft 3 to provide the rotating shaft 3 with the power to rotate around its own axis. The reciprocating extension mechanism is connected to both the rotating shaft 3 and the drive mechanism. During the rotation of the rotating shaft 3 driven by the drive mechanism, the reciprocating extension mechanism converts the rotational motion into the vertical reciprocating sliding motion of the rotating shaft 3. Furthermore, through its structural design, the stroke of the rotating shaft 3 increases with each downward movement, thereby achieving the effect of the rotating shaft 3 continuously extending downward and drilling. The drill bit 4 is detachably mounted on the lower end of the shaft 3 and rotates and slides back and forth with the shaft 3. When performing cutting and rock breaking operations, the rotational motion provides circumferential cutting capability, and the reciprocating sliding motion provides axial impact capability. The superposition of the two motion forms improves the rock breaking efficiency, while the progressively increasing downward stroke ensures the continuous accumulation of drilling depth, ultimately achieving efficient and continuous directional drilling operations.

[0034] As a further embodiment of the present invention, the lifting mechanism includes a guide rail 5 and a slide block 6, wherein the guide rail 5 is vertically arranged on the base 1; The slide block 6 is vertically slidably mounted on the guide rail 5, and the slide frame 2 is mounted on the slide block 6; A cylinder 7 is vertically mounted on the top of the guide rail 5, and the output end of the cylinder 7 is connected to the slide 2; When the output end of the cylinder 7 extends or retracts, the slide 2 will move vertically under the constraints of the guide rail 5 and the slide block 6.

[0035] In this embodiment, please refer to Figure 1 and Figure 2 The guide rail 5 is vertically fixed on the base 1, forming a guide rail for the lifting and lowering of the slide 2. The slide 6 is vertically slidably set on the guide rail 5, and the slide 2 is installed on the slide 6, thus forming a hierarchical structure in which the base 1, guide rail 5, slide 6, and slide 2 are connected in sequence. The cylinder 7 is vertically installed on the top of the guide rail 5, and its output end extends downward and is connected to the slide 2, forming the driving source for the lifting and lowering of the slide 2. When the output end of cylinder 7 extends, it pushes the slide 2, which in turn drives the slide block 6 to slide downward along the guide rail 5, thus lowering the slide 2 as a whole. When the output end of cylinder 7 retracts, it pulls the slide 2, which in turn drives the slide block 6 to slide upward along the guide rail 5, thus raising the slide 2 as a whole. Throughout the entire lifting and lowering process, the guide rail 5 and the slide block 6 cooperate with each other to provide vertical movement limits for the slide 2, ensuring that the slide 2 always moves smoothly vertically along the predetermined trajectory, thereby adapting to different drilling depth requirements.

[0036] As a further embodiment of the present invention, the driving mechanism includes a horizontal plate 8, a collar 9 and a rotating shaft 10, wherein the horizontal plate 8 is horizontally arranged on the slide 2; The collar 9 is rotatably mounted on the horizontal plate 8, and the rotating shaft 10 is rotatably mounted on the slide 2; The rotating shaft 3 and the collar 9 are slidably coupled coaxially. The outer wall of the rotating shaft 3 is provided with a protrusion 301 along its length direction, and the inner wall of the collar 9 is provided with a groove 901 along its length direction. The protrusion 301 is slidably fitted into the groove 901. One end of the rotating shaft 10 is coaxially provided with a drive sprocket 11, and the outer wall of the collar 9 is coaxially provided with a driven sprocket 12. The drive sprocket 11 and the driven sprocket 12 are connected by a chain 13. The drive mechanism also includes a geared motor 14 and a rotating drum 15. The geared motor 14 is mounted on the slide 2, and the rotating drum 15 is vertically rotatably mounted on the slide 2. The output end of the geared motor 14 is coaxially connected to the rotating drum 15. The outer wall of the rotating drum 15 is coaxially provided with a driving gear 16, the outer wall of the rotating shaft 10 is coaxially provided with a driven gear 17, and the slide 2 is rotatably provided with transmission gears 18 that mesh with the driving gear 16 and the driven gear 17 respectively.

[0037] In this embodiment, please refer to Figure 3 , Figure 4 and Figure 5 A horizontal plate 8 is horizontally set on the slide 2 to provide rotational support for the collar 9. The collar 9 is rotatably set on the horizontal plate 8 to form a ring structure that can rotate around a vertical axis. The rotating shaft 3 and the collar 9 are coaxially configured and form a sliding fit relationship between them. A protruding post 301 is provided on the outer wall of the rotating shaft 3 along the length direction, and a groove 901 is provided on the inner wall of the collar 9 along the length direction. The protruding post 301 is slidably fitted into the groove 901. This structure allows the rotating shaft 3 to slide axially relative to the collar 9. At the same time, the rotation of the collar 9 can drive the rotating shaft 3 to rotate synchronously through the engagement of the protruding post 301 and the groove 901. A rotating shaft 10 is rotatably mounted on a slide 2. One end of the shaft is coaxially mounted with a drive sprocket 11. A driven sprocket 12 is coaxially mounted on the outer wall of a collar 9. The drive sprocket 11 and the driven sprocket 12 are connected by a chain 13 to form a chain drive pair. A reduction motor 14 is mounted on the slide 2. Its output end is coaxially connected to a rotating drum 15, which is vertically rotatably mounted on the slide 2, to drive the rotating drum 15 to rotate. A drive gear 16 is coaxially mounted on the outer wall of the rotating drum 15. A driven gear 17 is coaxially mounted on the outer wall of the rotating shaft 10. A transmission gear 18 is rotatably mounted on the slide 2. The transmission gear 18 meshes with both the drive gear 16 and the driven gear 17 to form a gear drive pair. The geared motor 14 outputs rotational power, driving the drum 15 and its drive gear 16 to rotate synchronously. The drive gear 16 transmits power to the driven gear 17 through the transmission gear 18, driving the rotating shaft 10 and its drive sprocket 11 to rotate. The drive sprocket 11 drives the driven sprocket 12 and the collar 9 to rotate through the chain 13. The collar 9 drives the rotating shaft 3 to rotate around its axis through the engagement of the protrusion 301 and the groove 901. During this process, the rotating shaft 3 achieves rotational motion under the drive of the collar 9, and can slide axially relative to the collar 9, thus providing a structural basis for the subsequent reciprocating extension motion.

[0038] As a further embodiment of the present invention, the reciprocating extension mechanism includes a slide plate 19, a rotating rod 20, and a collar 21. The slide plate 19 is vertically slidably disposed on the slide frame 2, the collar 21 is mounted on the slide plate 19, the rotating rod 20 is rotatably engaged with the collar 21, and the top of the rotating rod 20 is inserted into the rotating cylinder 15 and slidably engaged with it. The outer wall of the rotating rod 20 is provided with a limiting post 2001 along its length direction, and the inner wall of the rotating cylinder 15 is provided with a limiting groove 1501 along its length direction. The limiting post 2001 is slidably fitted into the limiting groove 1501. The reciprocating extension mechanism also includes a threaded rod 22, a threaded sleeve 23, and a square block 24. The top of the threaded rod 22 is connected to the bottom of the rotating rod 20. The threaded sleeve 23 is slidably engaged with the square block 24. The square block 24 is mounted on the slide 2 via a bracket 25. The bottom of the threaded rod 22 is inserted into the threaded sleeve 23 and they are threadedly engaged with each other. The outer wall of the threaded sleeve 23 is provided with a pin 2301 along its length direction, and the inner wall of the square block 24 is provided with a pin groove 2401 along its length direction. The pin 2301 is slidably fitted into the pin groove 2401. The bottom of the threaded sleeve 23 is provided with a coupling 26, and the top of the rotating shaft 3 is rotatably connected to the coupling 26. The slide plate 19 is provided with a ring seat 27, which is slidably sleeved on the outer wall of the rotating shaft 10. The outer wall of the rotating shaft 10 is provided with an annular track groove 1001 along its length direction. The inner wall of the ring seat 27 is rolled and embedded with steel balls 28, which are also rolled and embedded in the annular track groove 1001.

[0039] In this embodiment, please refer to Figure 7 , Figure 8 , Figure 10 and Figure 11 The slide plate 19 is vertically slidably mounted on the slide frame 2. The collar 21 is installed on the slide plate 19. The rotating rod 20 and the collar 21 form a rotational engagement relationship. The top of the rotating rod 20 is inserted into the rotating cylinder 15 and slidably engaged with it. A limiting post 2001 is provided on the outer wall of the rotating rod 20 along the length direction. A limiting groove 1501 is provided on the inner wall of the rotating cylinder 15 along the length direction. The limiting post 2001 is slidably fitted into the limiting groove 1501. This structure allows the rotating rod 20 to slide axially relative to the rotating cylinder 15. At the same time, the rotation of the rotating cylinder 15 can drive the rotating rod 20 to rotate synchronously through the engagement of the limiting post 2001 and the limiting groove 1501. The top of the threaded rod 22 is connected to the bottom of the rotating rod 20. The threaded sleeve 23 is slidably engaged with the square block 24. The square block 24 is mounted on the slide 2 via the bracket 25. The bottom of the threaded rod 22 is inserted into the threaded sleeve 23 and threadedly engaged with it. A pin 2301 is provided on the outer wall of the threaded sleeve 23 along the length direction. A pin groove 2401 is provided on the inner wall of the square block 24 along the length direction. The pin 2301 is slidably fitted into the pin groove 2401. This structure allows the threaded sleeve 23 to slide axially relative to the square block 24. At the same time, the square block 24 restricts the rotational freedom of the threaded sleeve 23 through the engagement of the pin 2301 and the pin groove 2401. A coupling 26 is provided at the bottom of the threaded sleeve 23. The top of the rotating shaft 3 is rotatably connected to the coupling 26. The ring seat 27 is set on the slide plate 19 and slidably sleeved on the outer wall of the rotating shaft 10. The outer wall of the rotating shaft 10 is provided with an annular track groove 1001 along the length direction. The inner wall of the ring seat 27 rolls and is embedded in the steel ball 28. The steel ball 28 rolls and is embedded in the annular track groove 1001 at the same time. This structure allows the slide plate 19 to move back and forth in the vertical direction as the rotating shaft 10 rotates. The rotating drum 15 rotates continuously under the drive of the geared motor 14. The engagement of the limiting post 2001 and the limiting groove 1501 drives the rotating rod 20 and the threaded rod 22 to rotate synchronously. Due to the threaded engagement between the threaded rod 22 and the threaded sleeve 23, and the fact that the threaded sleeve 23 is restricted from rotating by the square block 24, the rotational motion of the threaded rod 22 is converted into the vertical linear motion of the threaded sleeve 23. The threaded sleeve 23 drives the rotating shaft 3 to slide vertically through the coupling 26. At the same time, the rotating shaft 3 continues to rotate under the drive of the collar 9, thereby realizing the compound motion of the rotating shaft 3 rotating and moving downward at the same time. The arrangement of the slide plate 19 and the ring seat 27 establishes a connection between the vertical movement of the threaded sleeve 23 and the rotating shaft 10. When the rotating shaft 10 rotates, the annular track groove 1001 applies a periodically changing vertical force to the ring seat 27 through the steel ball 28, driving the slide plate 19 and the collar 21 to reciprocate in the vertical direction. The collar 21 drives the rotating rod 20 and the threaded rod 22 to reciprocate synchronously. The threaded rod 22 continues to rotate during the reciprocating movement, and its threaded engagement with the threaded sleeve 23 causes the stroke of the threaded sleeve 23 to increase gradually with each downward movement, thereby achieving a continuous downward drilling effect with the downward stroke of the rotating shaft 3 increasing gradually.

[0040] A processing method for a directional drilling rig suitable for electrified low-carbon mining as described above, characterized by comprising the following steps: Step 1: Positioning and initial height adjustment of the device. Fix the base to the mining face, start the cylinder, and drive the slide to move vertically along the guide rail according to the target drilling depth requirements. Adjust the slide to the appropriate working height position to complete the initial configuration of the device. Step 2: Rotary power transmission and shaft rotation drive. Start the geared motor, and the drum rotates under the drive of the geared motor. Through the sequential meshing of the drive gear, transmission gear and driven gear, the rotating shaft and its drive sprocket rotate. The drive sprocket drives the driven sprocket and collar to rotate through the chain. The collar drives the rotating shaft to rotate continuously around its axis through the engagement of the protrusion and groove, providing circumferential cutting power for the drill bit. Step 3: Reciprocating extension motion and incremental drilling. During the rotation of the rotating shaft, the annular track groove applies a periodically changing vertical force to the ring seat through steel balls, driving the slide plate and collar to reciprocate in the vertical direction. The collar drives the rotating rod and threaded rod to reciprocate synchronously. The rotating rod continues to rotate with the rotating drum under the interlocking action of the limiting post and the limiting groove. The rotational motion of the threaded rod is converted into the vertical linear motion of the threaded sleeve under the rotation restriction of the square block on the threaded sleeve. The threaded sleeve drives the rotating shaft to rotate and slide vertically reciprocally through the coupling. The continuous rotation of the threaded rod during the reciprocating motion causes the stroke of the threaded sleeve to increase progressively with each downward movement, thereby realizing the continuous downward drilling of the drill bit driven by the rotating shaft. Step 4: Adaptive adjustment and cyclic operation of drilling depth. As the drilling depth increases, when the slide position deviates from the appropriate working height range, the cylinder is restarted to adaptively adjust the slide height, so that the slide returns to the appropriate position. At the same time, the drill bit continues to perform rotary cutting and axial impact rock breaking operations under the drive of the shaft. Steps 2 to 4 are repeated until the directional drilling operation at the target depth is completed.

10. A method for a directional drilling apparatus suitable for electrified low-carbon mining as described in any one of claims 1-9, characterized in that, Includes the following steps: Step 1: Positioning and initial height adjustment of the device. Fix the base to the mining face, start the cylinder, and drive the slide to move vertically along the guide rail according to the target drilling depth requirements. Adjust the slide to the appropriate working height position to complete the initial configuration of the device. Step 2: Rotary power transmission and shaft rotation drive. Start the geared motor, and the drum rotates under the drive of the geared motor. Through the sequential meshing of the drive gear, transmission gear and driven gear, the rotating shaft and its drive sprocket rotate. The drive sprocket drives the driven sprocket and collar to rotate through the chain. The collar drives the rotating shaft to rotate continuously around its axis through the engagement of the protrusion and groove, providing circumferential cutting power for the drill bit. Step 3: Reciprocating extension motion and incremental drilling. During the rotation of the rotating shaft, the annular track groove applies a periodically changing vertical force to the ring seat through steel balls, driving the slide plate and collar to reciprocate in the vertical direction. The collar drives the rotating rod and threaded rod to reciprocate synchronously. The rotating rod continues to rotate with the rotating drum under the interlocking action of the limiting post and the limiting groove. The rotational motion of the threaded rod is converted into the vertical linear motion of the threaded sleeve under the rotation restriction of the square block on the threaded sleeve. The threaded sleeve drives the rotating shaft to rotate and slide vertically reciprocally through the coupling. The continuous rotation of the threaded rod during the reciprocating motion causes the stroke of the threaded sleeve to increase progressively with each downward movement, thereby realizing the continuous downward drilling of the drill bit driven by the rotating shaft. Step 4: Adaptive adjustment and cyclic operation of drilling depth. As the drilling depth increases, when the slide position deviates from the appropriate working height range, the cylinder is restarted to adaptively adjust the slide height, so that the slide returns to the appropriate position. At the same time, the drill bit continues to perform rotary cutting and axial impact rock breaking operations under the drive of the shaft. Steps 2 to 4 are repeated until the directional drilling operation at the target depth is completed.
