Description

Technical Field

[0001] The invention relates to the technical field of stone drilling, and in particular to a device for quickly drilling stones with multiple hole sizes. Background Art

[0002] Stone is a natural or artificial rock material that can be used in construction, decoration, handicraft production and other fields after mining and processing. It has rich varieties, unique physical and chemical properties and a wide range of application scenarios. Stone mainly includes natural stone and artificial stone. Natural stone includes granite, sedimentary rock and metamorphic rock. Granite is mainly composed of minerals such as quartz, feldspar, and mica, and has a dense structure. Sedimentary rock is mainly divided into marble and sandstone. Marble is calcium carbonate, formed by metamorphism, with rich texture. It is mostly used for interior wall and floor decoration, or for sculpture. and handicrafts, sandstone is made of sand particles cemented together, with a loose and porous texture, sound absorption and heat insulation, and strong carveability, but low strength, easy to absorb water and cause weathering, and is mostly used in garden landscapes or interior decoration. Metamorphic rock is easily split into thin plates, and is mostly used in roof tiles or garden trails. Artificial stone mainly includes quartz stone or microcrystalline stone. Quartz stone is mainly made of quartz sand, resin, and pigment, and is formed under high pressure. It is mostly used in kitchen countertops, bathroom cabinet countertops, and wall decoration. The surface of microcrystalline stone is as smooth as a mirror, extremely resistant to stains, and has delicate patterns. It is mostly used in indoor floors, walls, and decorative lines.

[0003] Stone drilling refers to the process of using professional tools to produce holes of specific diameter and depth in natural stone or artificial stone. It usually uses a solid drill bit or a hollow drill bit, and is driven by a power source to rotate, so that the drill bit applies pressure on the surface of the stone and realizes the drilling of the stone.

[0004] Although the drilling device in the prior art has many benefits during use, it still has the following problems: the adjustment of the drill rod is not perfect. Due to different drilling requirements, the diameter of the drill hole on the stone surface is also different, and the existing drill rod is not convenient for speed change, which affects the drilling efficiency of the drilling device on the stone. Summary of the Invention

[0005] In view of the problems in the prior art, the present invention provides a device for quickly drilling holes in stones with multiple specifications and diameters.

[0006] The technical solution adopted by the present invention to solve the technical problem is a rapid drilling device for stones with multiple specifications and apertures, including a driving mechanism, a storage mechanism, a scraping mechanism, a limiting mechanism, a guiding mechanism, an assembly mechanism and an ash discharge mechanism. The driving mechanism includes a base plate and a ball screw, and the ball screw is installed on the upper surface of the base plate;

[0007] The storage mechanism includes a storage cover, and the storage cover is used to provide shielding protection;

[0008] The scraping mechanism includes a support rod and a plurality of scrapers, wherein the support rod is used to guide the moving track, and the plurality of scrapers are used to scrape and clean the adhered stones;

[0009] The limiting mechanism includes a blocking plate and a plurality of slide rails, wherein the blocking plate is used to block the interior of the storage cover, and the slide rails are used to limit the movement trajectory;

[0010] The assembly mechanism includes a connecting seat, the connecting seat is located between the slide rails, and an assembly hole is opened on the outer side of the connecting seat;

[0011] The ash discharge mechanism includes an ash discharge pipe, and the ash discharge pipe is used to discharge the air inside the storage cover.

[0012] By adopting the above technical solution, the bottom plate provides a stable working platform for the whole device, and the ball screw can realize the adjustment of the working position of the fixed seat, so as to drive the position of the driving rod to move, so as to meet the subsequent pushing out and drilling of the drill rod. The storage cover can store and protect multiple drill rods to prevent damage to the drill rod by external equipment or rain, thereby ensuring the service life of the drill rod. When the staff drives the support rod to rotate, the support ring can carry multiple drill rods to rotate synchronously, thereby achieving the purpose of adjusting the position of the drill rod and ensuring that the drill rods at different positions can be adjusted to the inlet and outlet, so as to meet the subsequent pushing out of the drill rod after the driving rod enters the inside of the inlet. When the driving rod pushes the drill rod to move, the slide rail limits the moving trajectory of the drill rod to ensure the horizontal movement of the drill rod, and the driving rod When the moving rod pushes the connecting seat to move, it pushes the support rod to move synchronously through the blocking plate, so that the scrapers on the inner walls of the remaining support rings move inside the spiral chip grooves of the drill rod. The scrapers achieve the purpose of cleaning the stone debris attached to the inside of the spiral chip grooves, avoiding the need for staff to manually clean the drill rod and reducing the work intensity of the staff. After the ball screw drives the fixed seat to the outside of the storage cover, the first conical disk contacts the second conical disk, and because the drive motor drives and drives the rod and drill rod to rotate and drill, when the drill rod rotates, the connecting shaft will follow the rotation and drive the air to flow through the wind wheel. The dust-laden air inside the storage cover and the cleaned stone debris are extracted through the ash discharge pipe, which is convenient for the subsequent centralized collection of stone debris and dust-laden air.

[0013] Specifically, a ball screw is provided at the upper end of the base plate, a fixed seat is installed at the upper end of the ball screw, the ball screw passes through one end of the base plate and is provided with a servo motor for providing power, the servo motor drives the ball screw to adjust the use position of the fixed seat, and a screw sheath is provided on the outer side of the ball screw;

[0014] A driving rod is provided inside the fixing seat, a driving motor is installed outside the fixing seat, a coupling is used to connect the driving motor and the driving rod, a first engaging block is provided at the end of the driving rod, and a first conical disk is provided outside the driving rod, and the first conical disk is used to transmit power.

[0015] By adopting the above technical solution, the servo motor can drive the ball screw to work, thereby adjusting the use position of the fixed seat, and realizing precise control of the use position of the fixed seat according to the matching controller. The servo motor first drives the driving rod to insert into the inlet and outlet through the ball screw, and inserts the first interlocking block into the interlocking groove of the drill rod at the inlet and outlet position. The first magnet is also bonded and fixed on both sides of the first interlocking block, so that the magnetic force of the first magnet and the second magnet in the interlocking groove attracts each other, which can drive the drill rod to rotate in a circle, thereby achieving the purpose of adaptively adjusting the position of the first interlocking block and the interlocking groove, and ensuring that the first interlocking block is inserted into the interlocking groove. The groove process is smooth, and then the ball screw continues to move, so that the drive rod pushes the connecting seat and the drill rod to move, and the movement of the drill rod is supported and limited by the slide rail, limit ring, slider and limit bearing to ensure the stability of the movement of the drill rod, and the movement of the connecting seat will push the support frame to move through the blocking plate. At this time, the scrapers on the outside of the remaining drill rods can scrape and clean the inside of the spiral chip groove. Finally, the drill rod passes through the inlet and outlet of the storage cover and moves out, so that the stone can be drilled by the drill rod. When the fixed seat carries the drive rod to the end point outside the storage cover, the first conical disk contacts the second conical disk and transmits rotational power to the connecting shaft.

[0016] Specifically, the outer sides of the storage cover and the sealing plate are both provided with an inlet and outlet, and the inlet and outlet are used to provide a moving space;

[0017] A plurality of tripods are installed at the lower end of the bottom plate, and a fixing frame for providing stability between structures is installed on the outer side of the storage cover, and the lower end of the fixing frame is connected to the tripod;

[0018] The inner wall of the storage cover is provided with an annular groove, the inner wall of the annular groove is designed in a convex shape, annular guide rails are provided on both sides of the inner wall of the storage cover, the inner circle of the annular guide rail is provided with a guide groove, and the end of the slide rail is arranged inside the guide groove.

[0019] By adopting the above technical solution, the inlet and outlet allow drill rods of the use diameter to enter and exit the storage cover, and the sealing plate can block the inside of the storage cover, reducing the probability of debris entering the storage cover when drilling stones. The bottom plate can ensure the stability of the use position through the tripod, and can ensure that the use position of the storage cover on the upper end face of the screw body is stable through the fixing frame. The annular groove can cooperate with the annular block to limit the connecting seat, ensuring the stability of the position of the connecting seat when it is inside the storage cover, ensuring that the connecting seat at different drill rods is restricted inside the storage cover, avoiding the support frame carrying it when it moves outside the unused drill rod, ensuring the stability of the scraper moving outside the unused drill rod, and the annular guide rail can limit the use position of the slide rail, ensuring the stability of the moving trajectory of the connecting seat on the outside of the slide rail, and ensuring the stability of the support of the slide rail and the limit ring on the connecting seat.

[0020] Specifically, the support rod is rotatably mounted at the center of the storage cover, a support frame is sleeved on the outside of the support rod, a plurality of support bearings are arranged on the outside of the support frame, a support ring is interference-mounted on the inner ring of the support bearing, and scrapers are arranged on both sides of the inner wall of the support ring;

[0021] The support rod is installed with a limit plate away from the outer wall of the support frame, and a return spring is sleeved on the outer side of the support rod. The elastic force of the return spring is used to maintain the relative position of the support frame.

[0022] By adopting the above technical solution, the shape of the support rod inside the storage cover is designed to be rectangular. When the staff manually turns the handle on the outside of the support rod, the rectangular shape can drive the support frame to rotate in a circle. Since the support ring and scraper of the support frame are located on the outside of the drill rod, the rotation of the support frame will drive multiple drill rods to rotate synchronously, which can adjust the position to ensure that the drill rods that meet the needs are located at the inlet and outlet. When the drill rods at the inlet and outlet are pushed out and rotated by the drive rod and the first interlocking block, the limit bearing supports the connecting seat and the rotation position of the drill rod to ensure the stability of the position of the drill rod during the drilling process, and the support bearing ensures that the support ring can rotate with the drill rod to avoid the drill rod The support frame is stuck inside the spiral chip groove. When the connecting seat and drill rod at the inlet and outlet are pushed out, the blocking plate will push the support frame to move synchronously, so that the support rings at other points move outside the unused drill rod, and the scraper scrapes and cleans the stone debris inside the spiral chip groove. The support bearing ensures that the position of the scraper can be adjusted following the spiral chip groove, ensuring that the scraper can clean the debris inside the spiral chip groove smoothly. When the support frame moves toward the sealing plate, it will squeeze the reset spring to store energy for the reset spring. When the driving rod moves back to reset, the reset spring releases energy and carries the connecting seat backward to reset through the support frame and the blocking plate. The limit plate limits the position of the reset spring.

[0023] Specifically, the limiting mechanism includes a limiting frame, a second interlocking block and a first magnet. The limiting frame is arranged on the outside of the support rod protruding from the storage cover. The limiting frame is installed with a plurality of second interlocking blocks toward the outside of the storage cover. The first magnet is bonded and fixed on both sides of the second interlocking blocks.

[0024] The outer side of the storage cover is provided with through holes whose number matches that of the second embedding blocks, and the second embedding blocks are located inside the through holes.

[0025] By adopting the above technical solution, before the staff rotates the support rod, the staff manually pulls the limit frame to disengage the second interlocking block from the interlocking groove of the drill rod and retract the second interlocking block into the through hole, so that the drill rod is free from the restriction of the second interlocking block. After that, the staff can adjust the use angle of the drill rod by rotating the support rod. When the staff pushes the limit frame to reset, the first magnet of the second interlocking block and the second magnet inside the interlocking groove attract each other. Therefore, due to the magnetic attraction, the connecting seat can be driven to rotate so that the angle of the interlocking groove corresponds to the position of the second interlocking block, which is convenient for the second interlocking block to be inserted into the interlocking groove, thereby achieving the purpose of magnetic positioning. The second interlocking block is located inside the interlocking groove, and the connecting seat will be restricted by the through hole to prevent the unused connecting seat and the drill rod outside it from rotating, thereby keeping the positions of different drill rods stable during the cleaning process.

[0026] Specifically, the baffle is installed on the outside of the storage cover, and the plurality of slide rails are located inside the storage cover. A limit ring is provided on the outside of the slide rail, and sliders are integrally formed on both sides of the limit ring. The ends of the sliders are located inside the slide rails, and the sliders and the slide rails support the limit rings.

[0027] The inner ring of the limiting ring is installed with a limiting bearing, and the connecting seat is installed on the inner ring of the limiting bearing. The limiting bearing is used to support the rotation position of the connecting seat.

[0028] By adopting the above technical solution, the sealing plate blocks the open area on the outside of the storage cover, and the slide rail can rotate through the annular guide rail, and the limiting ring can maintain the stability of the moving trajectory on the outside of the slide rail through the slider, ensuring that the horizontal movement of the drill rod is stable and smooth, and the limiting ring can support the connecting seat through the limiting bearing and the slide rail, ensuring that the use position of the connecting seat is relatively stable, and ensuring that the rotation position of the connecting seat and the drill rod is stable and smooth.

[0029] Specifically, an assembly hole is provided at the end of the connecting seat, a drill rod is placed inside the assembly hole, and a spiral chip removal groove is provided on the outside of the drill rod, and the spiral chip removal groove is used to discharge debris during the drilling process of the drill rod;

[0030] The assembly hole and the outer side of the drill rod are both provided with locking holes, and fixing bolts are provided inside the locking holes. The fixing bolts are used to lock and fix the drill rod.

[0031] By adopting the above technical solution, the fixing bolts lock and fix the drill rod through the locking holes to ensure the stability of the connection between the drill rod and the connecting seat, and the diameters of the drill rods at multiple points can be adjusted according to actual usage requirements to ensure that the sizes of the drill rods at multiple points are different, thereby enabling rapid replacement of drill rods of different specifications, and the spiral chip groove can discharge debris in time during the drilling process to avoid debris accumulation in the drill hole.

[0032] Specifically, a blocking plate for limiting the movement trajectory of the scraper is integrally formed on the outer side of the connecting seat;

[0033] The connecting seat is integrally formed with an annular block away from the outer side of the blocking plate, and the annular block is used to limit the position of the connecting seat. A rectangular fitting groove is opened at the end of the connecting seat, and second magnets are bonded to both sides of the inner wall of the fitting groove.

[0034] By adopting the above technical solution, the blocking plate can limit the use position of the support frame, ensuring that the scraper accurately acts on the inside of the spiral chip groove during the scraping process, thereby ensuring the scraping effect. When the drill rod follows the support frame to adjust its position, the annular block on the outside of the connecting seat will enter the annular groove to limit the position of the connecting seat. The interlocking groove is used to adapt to the first interlocking block and the second interlocking block, which can limit or transmit the drill rod, and the second magnet cooperates with the first magnet to adjust the use angle of the interlocking groove with the first interlocking block or the second interlocking block respectively, thereby ensuring the smoothness of the process of inserting the first interlocking block or the second interlocking block into the interlocking groove.

[0035] Specifically, the ash discharge pipe is installed at the lower end of the storage cover, a connecting pipe is provided at the end of the ash discharge pipe away from the storage cover, and flanges are installed on the outer side of the ash discharge pipe and the outer walls at both ends of the connecting pipe.

[0036] By adopting the above technical solution, the dusty air or debris inside the storage hood can be discharged through the ash discharge pipe and the connecting pipe. The flange ensures the stability and sealing of the connection between the ash discharge pipe and the connecting pipe, and can ensure the stability of the connection between the connecting pipe and the external collection container or dust collector, so that the dusty air or debris can be collected centrally.

[0037] Specifically, a bearing seat is installed at the bend of the connecting pipe, a connecting shaft is rotatably installed on the inner ring of the bearing seat, and a second conical disk for receiving power is installed at the end of the connecting shaft, and the power received by the second conical disk can drive the connecting shaft to rotate;

[0038] The end of the connecting shaft away from the second conical disk is screw-connected with a wind wheel for driving air flow, and the wind wheel is located inside the connecting pipe.

[0039] By adopting the above technical solution, when the driving rod rotates, the first conical disk contacts the conical surface of the second conical disk and can transmit power, thereby driving the connecting shaft and the wind wheel to rotate. The wind wheel drives the air flow inside the connecting pipe, so that the debris and dust-containing air in the storage cover are discharged, and the relative cleanliness of the inside of the storage cover is maintained.

[0040] Beneficial effects of the present invention:

[0041] The invention discloses a rapid drilling device for stones with multiple specifications and apertures. The device can store and protect the drill rod through a storage cover, and can drive the support ring to rotate synchronously by manually rotating the support rod, thereby completing the adjustment of the inlet and outlet positions of drill rods of different specifications, shortening the replacement efficiency of the drill rod, and thus improving the drilling efficiency of the equipment for stones.

[0042] The invention discloses a rapid drilling device for stones with multiple apertures. When a driving rod pushes the drill rod to move, a blocking plate synchronously drives a scraper to clean debris along a spiral chip groove, thereby avoiding manual cleaning, ensuring the cleanliness of the interior of the spiral chip groove, and facilitating smooth chip removal when the drill rod is used next time.

[0043] The invention discloses a rapid drilling device for stones with multiple apertures. The wind wheel is driven by a first conical disk to realize automatic dust extraction from the dust discharge pipe, so that debris and dust-laden air in the storage cover are discharged, thereby maintaining relative cleanliness of the interior of the storage cover.

[0057] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0058] In order to save manpower and improve efficiency, as an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 As shown, the multi-specification aperture stone rapid drilling device of the present invention includes a driving mechanism, a receiving mechanism, a scraping mechanism, a limiting mechanism, a guiding mechanism, an assembly mechanism and an ash discharge mechanism. The driving mechanism includes a base plate 1 and a ball screw 17. The ball screw 17 is installed on the upper end surface of the base plate 1.

[0059] The storage mechanism includes a storage cover 2, which is used to provide shielding protection;

[0060] The scraping mechanism includes a support rod 3 and a plurality of scrapers 36. The support rod 3 is used to guide the moving track, and the plurality of scrapers 36 are used to scrape and clean the adhered stones.

[0061] The limiting mechanism includes a blocking plate 5 and a plurality of slide rails 51. The blocking plate 5 is used to block the interior of the storage cover 2, and the slide rails 51 are used to limit the movement trajectory.

[0062] The assembly mechanism includes a connecting seat 6, which is located between the slide rails 51 and has an assembly hole 61 formed on the outer side of the connecting seat 6;

[0063] The ash discharge mechanism includes an ash discharge pipe 7 , which is used to discharge the air inside the storage cover 2 .

[0064] When in use, the base plate 1 provides a stable platform for the entire device, and the ball screw 17 can adjust the position of the fixing seat 13, so that the position of the driving rod 12 can be driven to move, so as to meet the subsequent pushing out and drilling of the drill rod 67. The storage cover 2 can store and protect multiple drill rods 67 to prevent damage to the drill rod 67 by external equipment or rain, thereby ensuring the service life of the drill rod 67. When the staff drives the support rod 3 to rotate, the support ring 35 can carry multiple drill rods 67 to rotate synchronously, thereby achieving the purpose of adjusting the position of the drill rod 67 and ensuring that the drill rods 67 at different positions can be adjusted to the inlet and outlet 22, so as to meet the subsequent pushing out of the drill rod 67 after the driving rod 12 enters the inside of the inlet. When the driving rod 12 pushes the drill rod 67 to move, the slide rail 51 limits the moving trajectory of the drill rod 67 to ensure the horizontal movement of the drill rod 67, and the driving rod 12 When pushing the connecting seat 6 to move, the support rod 3 is pushed to move synchronously through the blocking plate 65, so that the scraper 36 on the inner wall of the remaining support ring 35 moves inside the spiral chip groove 68 of the drill rod 67. The scraper 36 achieves the purpose of cleaning the stone debris attached to the inside of the spiral chip groove 68, avoiding the need for staff to manually clean the drill rod 67, reducing the work intensity of the staff. After the ball screw 17 drives the fixed seat 13 to move to the outside of the storage cover 2, the first conical disk 16 contacts the second conical disk 75, and because the drive motor 14 drives and drives the rod 12 and the drill rod 67 to rotate for drilling, when the drill rod 67 rotates, the connecting shaft 74 will follow the rotation and drive the air flow through the wind wheel 76, and the dust-laden air inside the storage cover 2 and the cleaned stone debris are extracted through the ash discharge pipe 7, which is convenient for the subsequent centralized collection of stone debris and dust-laden air.

[0065] To drive the rotation, for example, Figure 3As shown, a ball screw 17 is provided at the upper end of the base plate 1, and a fixed seat 13 is installed at the upper end of the ball screw 17. The ball screw 17 passes through the base plate 1 and a servo motor 15 for providing power is provided at one end. The servo motor 15 drives the ball screw 17 to adjust the use position of the fixed seat 13. A screw sheath 18 is provided on the outer side of the ball screw 17;

[0066] A driving rod 12 is provided inside the fixed seat 13, and a driving motor 14 is installed on the outside of the fixed seat 13. The driving motor 14 and the driving rod 12 are connected by a coupling. A first engaging block 19 is provided at the end of the driving rod 12, and a first conical disk 16 is provided on the outside of the driving rod 12. The first conical disk 16 is used to transmit power.

[0067] The fixing seat 13 and the ball screw 17 are connected by screws, and the driving motor 14 is screwed to the outside of the fixing seat 13. The first engaging block 19 and the driving rod 12 are connected by a pin shaft.

[0068] During use, the servo motor 15 can drive the ball screw 17 to work, thereby adjusting the use position of the fixing seat 13 and realizing precise control of the use position of the fixing seat 13 according to the matching controller. The servo motor 15 first drives the driving rod 12 to insert into the inlet and outlet 22 through the ball screw 17, and inserts the first interlocking block 19 into the interlocking groove 63 of the drill rod 67 at the position of the inlet and outlet 22. The first magnet 42 is also bonded and fixed on both sides of the first interlocking block 19, so that the magnetic force of the first magnet 42 and the second magnet 64 inside the interlocking groove 63 attracts each other, which can drive the drill rod 67 to rotate in a circle, thereby achieving the purpose of adaptively adjusting the positions of the first interlocking block 19 and the interlocking groove 63, and ensuring the smooth insertion of the first interlocking block 19 into the interlocking groove 63. After that, the ball screw 17 continues to move, causing the driving rod 12 to push the connecting seat 6 and the drill rod 67 to move, and the movement of the drill rod 67 is supported and restricted by the slide rail 51, the limit ring 52, the slider 53 and the limit bearing 54, ensuring the stability of the movement of the drill rod 67, and the movement of the connecting seat 6 will push the support frame 33 to move through the blocking plate 65. At this time, the scraper 36 on the outside of the remaining drill rod 67 can scrape and clean the inside of the spiral chip groove 68. Finally, the drill rod 67 passes through the inlet and outlet 22 of the storage cover 2 and moves out, so that the stone can be drilled by the drill rod 67. When the fixed seat 13 carries the driving rod 12 to the end point outside the storage cover 2, the first conical disk 16 contacts the second conical disk 75 and transmits rotational power to the connecting shaft 74.

[0069] To provide support, for example, Figure 5 As shown, the outside of the storage cover 2 and the sealing baffle 5 are both provided with an inlet and outlet 22, which are used to provide a moving space;

[0070] A plurality of legs 11 are installed at the lower end of the bottom plate 1, and a fixing frame for providing stability between the structures is installed on the outside of the storage cover 2, and the lower end of the fixing frame is connected to the legs 11;

[0071] An annular groove 23 is provided on the inner wall of the storage cover 2. The inner wall of the annular groove 23 is designed to be convex. Annular guide rails 24 are provided on both sides of the inner wall of the storage cover 2. A guide groove is provided on the inner circle of the annular guide rail 24, and the end of the slide rail 51 is provided inside the guide groove.

[0072] The size of the inlet and outlet 22 is larger than that of the connecting seat 6. The tripod 11 and the base plate 1 can be connected by screws, and the storage cover 2 is connected to the tripod 11 by screws through the fixing frame to fix the position of the storage cover 2. The annular block 62 is inside the annular groove 23, thereby limiting the position of the connecting seat 6. The annular guide rail 24 is screwed to the inner wall of the storage cover 2, and the slide rail 51 is slidably installed inside the guide groove of the annular guide rail 24, so that the position adjustment of the slide rail 51 is stable and smooth.

[0073] When in use, the inlet and outlet 22 allows the drill rod 67 of the use diameter to enter and exit the storage cover 2, and the sealing plate 5 can block the inside of the storage cover 2, reducing the probability of debris entering the storage cover 2 when drilling stones. The bottom plate 1 can ensure the stability of the use position through the tripod 11, and can ensure that the storage cover 2 is stable in the use position on the upper end face of the screw body through the fixing frame. The annular groove 23 can cooperate with the annular block 62 to limit the connecting seat 6, ensuring that the position of the connecting seat 6 is stable when it is inside the storage cover 2, and ensuring that the connecting seat 6 at the unused drill rod 67 is restricted inside the storage cover 2, avoiding the support frame 33 from carrying it with it when moving outside the unused drill rod 67, ensuring the stability of the movement of the scraper 36 outside the unused drill rod 67, and the annular guide rail 24 can limit the use position of the slide rail 51, ensuring that the moving trajectory of the connecting seat 6 outside the slide rail 51 is stable, and ensuring that the slide rail 51 cooperates with the limit ring 52 to support the connecting seat 6 stably.

[0074] To scrape off debris, for example, Figure 5 As shown, the support rod 3 is rotatably mounted at the center of the storage cover 2. A support frame 33 is sleeved on the outside of the support rod 3. A plurality of support bearings 34 are arranged on the outside of the support frame 33. A support ring 35 is interference-fitted on the inner ring of the support bearing 34. Scrapers 36 are arranged on both sides of the inner wall of the support ring 35.

[0075] A limit plate 31 is installed on the support rod 3 away from the outer wall of the support frame 33. A return spring 32 is sleeved on the outer side of the support rod 3. The elastic force of the return spring 32 is used to maintain the relative position of the support frame 33.

[0076] The support rod 3 and the storage cover 2 are rotatably connected by a ball bearing to ensure that the support rod 3 inside the storage cover 2 rotates smoothly, and the shape of the support rod 3 inside the storage cover 2 and the shape of the internal cavity of the support frame 33 are both rectangular, ensuring that the rotation of the support frame 33 can carry the support rod 3 with the rotation, the support bearing 34 is interference fitted on the inner wall of the support frame 33, and the support ring 35 is interference fitted on the inner ring of the support bearing 34, which can ensure that the position of the scraper 36 can be adjusted, the scraper 36 and the support ring 35 are cast as one piece, and the limit plate 31 and the support rod 3 are connected by screws to ensure that the position of the limit plate 31 outside the support rod 3 is stable, and the return spring 32 provides support force to the support frame 33, which can maintain the position of the support frame 33.

[0077] When in use, the shape of the support rod 3 inside the storage cover 2 is designed to be rectangular. When the staff manually turns the handle on the outside of the support rod 3, the rectangular shape can drive the support frame 33 to rotate in a circle. Since the support ring 35 and the scraper 36 of the support frame 33 are located on the outside of the drill rod 67, the rotation of the support frame 33 will drive multiple drill rods 67 to rotate synchronously, which can adjust the position to ensure that the drill rod 67 that meets the needs is located at the inlet and outlet 22. When the drill rod 67 at the inlet and outlet 22 is pushed out and rotated by the drive rod 12 and the first interlocking block 19, the limit bearing 54 supports the rotation position of the connecting seat 6 and the drill rod 67 to ensure that the position of the drill rod 67 is stable during the drilling process, and the support bearing 34 ensures that the support ring 35 can rotate with the drill rod 67 to prevent the drill rod 67 from being located in the spiral chip removal The groove 68 is stuck, and when the connecting seat 6 and the drill rod 67 of the inlet and outlet 22 are pushed out, the blocking plate 65 will push the support frame 33 to move synchronously, so that the support rings 35 at the remaining points move outside the unused drill rod 67, and the scraper 36 scrapes and cleans the stone debris inside the spiral chip groove 68, and the support bearing 34 ensures that the position of the scraper 36 can be adjusted to follow the spiral chip groove 68, ensuring that the scraper 36 can clean the debris inside the spiral chip groove 68 smoothly, and when the support frame 33 moves toward the sealing plate 5, it will squeeze the reset spring 32, realizing the energy storage of the reset spring 32. When the driving rod 12 moves back to reset, the reset spring 32 releases energy and carries the connecting seat 6 backward to reset through the support frame 33 and the blocking plate 65, and the limit plate 31 limits the position of the reset spring 32.

[0078] In order to limit the unused drill rod 67 positions, for example, Figure 7 As shown, the limiting mechanism includes a limiting frame 4, a second interlocking block 41 and a first magnet 42. The limiting frame 4 is arranged on the outside of the support rod 3 protruding from the storage cover 2. The limiting frame 4 is installed with multiple second interlocking blocks 41 facing the outside of the storage cover 2. The first magnet 42 is bonded and fixed on both sides of the second interlocking blocks 41.

[0079] The outer side of the storage cover 2 is provided with through holes 21 whose number matches the number of the second engaging blocks 41 , and the second engaging blocks 41 are located inside the through holes 21 .

[0080] The limit frame 4 is slidably installed on the outside of the storage cover 2, and the position of the limit frame 4 can be adjusted. The second interlocking block 41 is connected to the limit frame 4 with screws. According to the position of the limit frame 4, the second interlocking block 41 can be controlled to be located inside the interlocking groove 63.

[0081] When in use, before the support rod 3 rotates, the staff manually pulls the limit frame 4 to disengage the second interlocking block 41 from the interlocking groove 63 of the drill rod 67 and retract the second interlocking block 41 into the through hole 21, so that the drill rod 67 is free from the restriction of the second interlocking block 41. After that, the staff can adjust the use angle of the drill rod 67 by rotating the support rod 3. When the staff pushes the limit frame 4 to reset, the first magnet 42 of the second interlocking block 41 and the second magnet 64 inside the interlocking groove 63 attract each other, so that due to magnetic attraction, the connecting seat 6 can be driven to rotate so that the angle of the interlocking groove 63 corresponds to the position of the second interlocking block 41, which is convenient for the second interlocking block 41 to be inserted into the interlocking groove 63, achieving the purpose of magnetic positioning, and the second interlocking block 41 is located inside the interlocking groove 63, which will restrict the connecting seat 6 through the through hole 21, preventing the unused connecting seat 6 and the drill rod 67 outside it from rotating, and keeping the positions of different drill rods 67 stable during the cleaning process.

[0082] To support the use position, for example, Figure 8 As shown, the baffle plate 5 is installed on the outside of the storage cover 2, and multiple slide rails 51 are located inside the storage cover 2. A limit ring 52 is provided on the outside of the slide rail 51. Slide blocks 53 are integrally formed on both sides of the limit ring 52. The ends of the slide blocks 53 are located inside the slide rails 51. The slide blocks 53 and the slide rails 51 support the limit ring 52.

[0083] A limiting bearing 54 is installed on the inner ring of the limiting ring 52 , and the connecting seat 6 is installed on the inner ring of the limiting bearing 54 . The limiting bearing 54 is used to support the rotation position of the connecting seat 6 .

[0084] The sealing plate 5 and the storage cover 2 are connected by screws, the end of the slider 53 is slidably installed inside the slide rail 51, the limit bearing 54 is interference installed on the inner ring of the limit ring 52, and the connecting seat 6 is interference installed on the inner ring of the limit bearing 54, and the limit ring 52 is located between the assembly hole 61 and the annular block 62.

[0085] When in use, the sealing plate 5 blocks the open part on the outside of the storage cover 2, and the slide rail 51 can rotate through the annular guide rail 24, and the limiting ring 52 can maintain the stable movement trajectory on the outside of the slide rail 51 through the slider 53, ensuring that the horizontal movement of the drill rod 67 is stable and smooth, and the limiting ring 52 can support the connecting seat 6 through the limiting bearing 54 and the slide rail 51, ensuring that the use position of the connecting seat 6 is relatively stable, and ensuring that the rotation position of the connecting seat 6 and the drill rod 67 is stable and smooth.

[0086] For drilling, for example, Figure 8 As shown, the end of the connecting seat 6 is provided with an assembly hole 61, a drill rod 67 is placed inside the assembly hole 61, and a spiral chip groove 68 is provided on the outside of the drill rod 67. The spiral chip groove 68 is used to discharge the debris during the drilling process of the drill rod 67;

[0087] Locking holes are provided on the outside of the assembly hole 61 and the drill rod 67 , and fixing bolts 66 are provided inside the locking holes. The fixing bolts 66 are used to lock and fix the drill rod 67 .

[0088] The fixing bolt 66 passes through the locking hole to fix the drill rod 67 inside the assembly hole 61 .

[0089] During use, the fixing bolt 66 locks and fixes the drill rod 67 through the locking hole to ensure the stability of the connection between the drill rod 67 and the connecting seat 6, and the diameter of the drill rod 67 at multiple points can be adjusted according to actual use requirements to ensure that the drill rods 67 at multiple points are of different sizes, so that drill rods 67 of different specifications can be quickly replaced, and the spiral chip groove 68 can discharge debris in time during the drilling process to avoid debris accumulation in the drill hole.

[0090] For linkage cleaning, for example, Figure 9 As shown, a blocking plate 65 is integrally formed on the outer side of the connecting seat 6 for limiting the moving track of the scraper 36;

[0091] The connecting seat 6 is integrally formed with an annular block 62 on the outside away from the blocking plate 65. The annular block 62 is used to limit the position of the connecting seat 6. A rectangular fitting groove 63 is opened at the end of the connecting seat 6. Second magnets 64 are bonded to both sides of the inner wall of the fitting groove 63.

[0092] The support frame 33 is located on the end surface of the blocking plate 65 facing the drill rod 67 , and the drill rod 67 is located in the inner ring of the support ring 35 , and the annular block 62 is located inside the annular groove 23 .

[0093] When in use, the blocking plate 65 can limit the use position of the support frame 33, ensuring that the scraper 36 accurately acts on the spiral chip groove 68 during the scraping process, thereby ensuring the scraping effect. When the drill rod 67 follows the support frame 33 to adjust its position, the annular block 62 on the outside of the connecting seat 6 will enter the annular groove 23 to limit the position of the connecting seat 6. The interlocking groove 63 is used to adapt to the first interlocking block 19 and the second interlocking block 41, and can limit or transmit the drill rod 67. The second magnet 64 cooperates with the first magnet 42 to adjust the use angle of the interlocking groove 63 to the first interlocking block 19 or the second interlocking block 41 respectively, thereby ensuring the smoothness of the process of inserting the first interlocking block 19 or the second interlocking block 41 into the interlocking groove 63.

[0094] For dust removal, for example, Figure 10 As shown, the ash discharge pipe 7 is installed at the lower end of the storage cover 2, and a connecting pipe 71 is provided at the end of the ash discharge pipe 7 away from the storage cover 2. Flanges 72 are installed on the outer side of the ash discharge pipe 7 and the outer walls of both ends of the connecting pipe 71.

[0095] When in use, the dusty air or debris inside the storage cover 2 can be discharged through the dust discharge pipe 7 and the connecting pipe 71. The flange 72 ensures the stability and sealing of the connection between the dust discharge pipe 7 and the connecting pipe 71, and can ensure the stability of the connection between the connecting pipe 71 and the external collection container or dust collector, so that the dusty air or debris can be collected in a centralized manner.

[0096] For dust removal, for example, Figure 11 As shown, a bearing seat 73 is installed at the bend of the connecting pipe 71, and a connecting shaft 74 is rotatably installed on the inner ring of the bearing seat 73. A second conical disk 75 for receiving power is installed at the end of the connecting shaft 74. The power received by the second conical disk 75 can drive the connecting shaft 74 to rotate.

[0097] The end of the connecting shaft 74 away from the second conical disk 75 is screwedly connected to a wind wheel 76 for driving air flow. The wind wheel 76 is located inside the connecting pipe 71.

[0098] The bearing seat 73 is interference-fitted on the outside of the connecting pipe 71 , and the connecting shaft 74 is interference-fitted on the inner ring of the bearing seat 73 . The second conical disk 75 and the wind wheel 76 are both screw-connected to the connecting shaft 74 .

[0099] During use, when the driving rod 12 rotates, the first conical disk 16 contacts the conical surface of the second conical disk 75 and is able to transmit power, thereby driving the connecting shaft 74 and the wind wheel 76 to rotate. The wind wheel 76 drives the air flow inside the connecting pipe 71, so that the debris and dust-containing air in the storage cover 2 are discharged, and the relative cleanliness of the inside of the storage cover 2 is maintained.

[0100] When using the present invention, the operator manually pulls the limit frame 4, causing the second interlocking block 41 to disengage the interlocking groove 63 of the drill rod 67 and retract into the through hole 21, thereby releasing the restriction on the drill rod 67. The operator then rotates the handle on the outside of the support rod 3, utilizing the rectangular shape of the support rod 3 to drive the support frame 33 to rotate in a circular manner, thereby driving the multiple drill rods 67 to rotate synchronously through the support ring 35, and adjusting the drill rod 67 that meets the current drilling requirements to the inlet and outlet 22 positions;

[0101] After the position adjustment of the drill rod 67 is completed, the limit frame 4 is pushed to reset. The first magnet 42 of the second interlocking block 41 and the second magnet 64 in the interlocking groove 63 attract each other, causing the connecting base 6 to rotate to a suitable angle, facilitating the insertion of the second interlocking block 41 into the interlocking groove 63. The connecting base 6 is restricted by the through hole 21, ensuring the stable position of the drill rod 67 in the non-working state.

[0102] The servo motor 15 drives the ball screw 17, which moves the fixed base 13 toward the storage cover 2, inserting the drive rod 12 into the inlet 22 and inserting the first interlocking block 19 into the interlocking groove 63 of the drill rod 67 at the inlet 22. The first magnets 42 on both sides of the first interlocking block 19 and the second magnets 64 in the interlocking groove 63 attract each other, achieving adaptive positioning and ensuring that the first interlocking block 19 and the interlocking groove 63 are accurately connected.

[0103] The ball screw 17 continues to move, and the drive rod 12 pushes the connecting seat 6 and the drill rod 67 to move along the slide rail 51. During this process, the limit ring 52 slides on the slide rail 51 through the slider 53, providing stable support for the drill rod 67; the limit bearing 54 ensures the rotational flexibility of the connecting seat 6 and the drill rod 67, ensuring that the drill rod 67 is smoothly pushed out of the storage cover 2;

[0104] During the push-out process of the drill rod 67, the blocking plate 65 on the outside of the connecting seat 6 pushes the support frame 33 to move synchronously, causing the scrapers 36 on the inner wall of the remaining support ring 35 to move within the spiral chip removal groove 68 of the non-working drill rod 67, scraping away the stone debris adhering to the groove. The support bearing 34 ensures that the scrapers 36 can flexibly adjust their position to follow the spiral trajectory of the spiral chip removal groove 68.

[0105] When the fixing seat 13 carries the driving rod 12 to move to the outer end point of the storage cover 2, the driving motor 14 drives the driving rod 12 to rotate through the coupling, and the first interlocking block 19 transmits the rotational power to the drill rod 67, so that the drill rod 67 drills the stone. The spiral chip groove 68 on the outer side of the drill rod 67 discharges the debris in time during the drilling process, and the first conical disk 16 on the outer side of the driving rod 12 contacts the second conical disk 75 at the end of the connecting shaft 74, transmitting the rotational power to the connecting shaft 74, and the connecting shaft 74 drives the wind wheel 76 to rotate in the connecting pipe 71, forming air flow, and the dust-laden air and the cleaned stone debris in the storage cover 2 are extracted through the ash discharge pipe 7, and are transported to the external collection container or dust collector through the connecting pipe 71 for centralized treatment;

[0106] After the drilling operation is completed, the servo motor 15 drives the ball screw 17 to move in the opposite direction, driving the drive rod 12 to retract. At this time, the compressed return spring 32 releases energy, pushing the connecting seat 6 to move backward and reset through the support frame 33 and the blocking plate 65, so that the drill rod 67 returns to its initial position.
