[0002] In the process of earthwork blasting, drilling is an extremely critical pre-process, the purpose of which is to provide precise holes for the burial of explosives. At present, most of the common drilling devices used for earthwork blasting construction on the market use a threaded structure to realize the sand and soil discharge function during the drilling process. Through the rotation of the threaded structure, the sand and soil generated by the drilling can be effectively transported upward along the thread groove and discharged out of the hole, which to a certain extent ensures the continuity and efficiency of the drilling operation. However, due to the lack of effective guidance and collection measures for the discharged sand and soil, it is very easy to accumulate near the hole.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments. Example 1

[0032] Reference Figures 1-11, which is the first embodiment of the present invention, provides a drilling device for earthwork blasting construction. The drilling device for earthwork blasting construction includes a collecting component 2, which can automatically collect the drilled sand and soil, and can guide the collected sand and soil to a designated location for discharge, thereby avoiding the accumulation of sand and soil around the hole.

[0033] The main structure 1 includes a gantry 11. The bottom of the gantry 11 is fixedly connected to a base plate 12. A mounting plate 13 is hinged on one side of the top of the base plate 12. The top of the mounting plate 13 is fixedly connected to a lifting member 14. A lifting block 15 is threadedly connected to the surface of the lifting member 14. A through slot 16 is provided on one side of the mounting plate 13. One side of the lifting block 15 passes through the through slot 16 and is fixedly connected to an upper cylinder 17. The bottom of the upper cylinder 17 is connected to the lower cylinder 18. The top of the upper cylinder 17 is fixedly connected to a drive motor 19. The output shaft of the drive motor 19 is fixedly connected to a drill rod 19-1. The bottom of the drill rod 19-1 passes through the upper cylinder 17 and the lower cylinder 18 and extends to the outside of the lower cylinder 18. The surface of the drill rod 19-1 is fixedly connected to a conveying blade 19-2. The gantry 11 serves as the basic supporting component, and a base plate 12 is firmly fixed to its bottom by welding or other means, thereby building a stable foundation for the entire device. On one side of the top of the base plate 12, a mounting plate 13 is installed by a hinged manner. This design enables the mounting plate 13 to swing around the hinge point as the axis, creating conditions for the subsequent realization of the inclined hole drilling function. A lifting member 14 is fixedly connected to the top of the mounting plate 13, and the surface of the lifting member 14 is connected to the lifting block 15 through a thread. When the lifting member 14 is running, based on the principle of thread transmission, the lifting block 15 will move up and down along the through groove 16 pre-opened on one side of the mounting plate 13, and the upper cylinder 17 and the lower cylinder 18 fixedly connected to the lifting block 15 will also move synchronously with the movement of the lifting block 15. A drive motor 19 is installed on the top of the upper cylinder 17, and its output shaft is fixedly connected to the drill rod 19-1. When the drive motor 19 is started, it will drive the drill rod 19-1 to rotate. At the same time, the conveying blade 19-2 fixed on the surface of the drill rod 19-1 also rotates accordingly. During the rotation process, the conveying blade 19-2 can transport the sand and soil produced by the drilling from the lower cylinder 18 upward to the upper cylinder 17.

[0034] The collecting assembly 2 includes a rotating plate 21 fixedly connected to the surface of the drill pipe 19-1, and both sides of the bottom of the upper cylinder 17 are connected to the collecting cylinder 22, and a sealing plate 23 is provided at the bottom of the collecting cylinder 22. Both sides of the bottom of the sealing plate 23 are fixedly connected to sliders 24, and the inner cavity of the slider 24 is slidably connected to a sliding rod 25. The side of the sliding rod 25 close to the lower cylinder 18 is fixedly connected to the lower cylinder 18, and one side of the sealing plate 23 is fixedly connected to a guide rod 26, and one side of the guide rod 26 is slidably connected to an inclined guide rail 27, one side of the inclined guide rail 27 is fixedly connected to the mounting plate 13, and the bottom of the inclined guide rail 27 is connected to a vertical guide rail 28, and one side of the vertical guide rail 28 is fixedly connected to the mounting plate 13. A scraper 29 is provided on the top of the sealing plate 23, and a discharge member 30 is provided at the bottom of the scraper 29, and is located at the top of the bottom plate 12, and an adjusting member 31 is fixedly connected to one side of the inner cavity of the bottom plate 12.

[0035] The collecting component 2 includes a rotating plate 21 fixedly mounted on the surface of the drill rod 19-1, which will rotate with the drill rod 19-1 and continuously push the sand in the upper cylinder 17 to the collecting cylinder 22 during the rotation. The collecting cylinder 22 is connected to the bottom of the upper cylinder 17 for receiving and collecting the transported sand. A sealing plate 23 is provided at the bottom of the collecting cylinder 22. Sliders 24 are fixedly connected to both sides of the bottom of the sealing plate 23. The inner cavity of the slider 24 forms a sliding connection with the slide rod 25. This design ensures that the sealing plate 23 can slide stably along the slide rod 25. A guide rod 26 is fixedly connected to one side of the sealing plate 23. The guide rod 26 forms a sliding fit with the inclined guide rail 27 and the vertical guide rail 28. During the rising process of the lifting block 15, the guide rod 26 will guide the sealing plate 23 to move under the guidance of the vertical guide rail 28 and the inclined guide rail 27, thereby realizing the opening and closing of the collecting cylinder 22.

[0036] A scraper 29 is provided on the top of the sealing plate 23. When the sealing plate 23 moves, the scraper 29 can clean the sand and soil adhering to the inner wall of the collecting tube 22, effectively preventing blockage. The discharge member 30 and the adjustment member 31 respectively assume the functions of sand discharge and device angle adjustment. Example 2

[0037] Reference Figures 1-11 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0038] Specifically, the lifting member 14 includes a first motor 14-1 fixedly connected to the top of the mounting plate 13, the output shaft of the first motor 14-1 is fixedly connected to the first screw rod 14-2, the surface of the first screw rod 14-2 is threadedly connected to the lifting block 15, and the bottom of the first screw rod 14-2 is rotatably connected to the first limit plate 14-3, and one side of the first limit plate 14-3 is fixedly connected to the mounting plate 13.

[0039] When the first motor 14-1 is working, it will drive the first screw rod 14-2 to rotate. Since the first screw rod 14-2 is connected to the lifting block 15 by a threaded connection, the rotation of the first screw rod 14-2 will cause the lifting block 15 to produce linear motion. The first limiting plate 14-3 is fixedly installed on the mounting plate 13 and forms a rotational connection with the bottom of the first screw rod 14-2. Its function is to support and limit the first screw rod 14-2, ensure the stability of the first screw rod 14-2 during the rotation process, and thereby realize the control of the lifting and lowering movement of the lifting block 15.

[0040] Specifically, the scraper 29 includes a tooth plate 29-1 fixedly connected to the top of the sealing plate 23, and a tooth ring 29-2 is rotatably connected to the bottom of the collecting cylinder 22 and cooperates with the tooth plate 29-1. The inner cavity of the tooth ring 29-2 is fixedly connected to the scraper 29-3.

[0041] The tooth plate 29-1 is fixedly installed on the top of the sealing plate 23. When the tooth plate 29-1 moves, it will drive the gear ring 29-2 to rotate through the meshing relationship, and the scraper 29-3 fixed in the inner cavity of the gear ring 29-2 will also rotate, thereby scraping off the sand and soil on the inner wall of the collecting tube 22. This structural design can effectively prevent sand and soil from accumulating on the inner wall of the collecting tube 22, ensure the normal use of the collecting tube 22, avoid equipment failure due to blockage, and greatly improve the reliability of the device.

[0042] Specifically, the discharge piece 30 includes a frame 30-1 fixedly connected to the other side of the mounting plate 13, the inner cavity of the frame 30-1 is rotatably connected to a rotating disk 30-2, the side of the rotating disk 30-2 away from the first screw rod 14-2 is fixedly connected to a connecting arm 30-3, and one side of the connecting arm 30-3 is fixedly connected to a discharge plate 30-4.

[0043] When the rotating disk 30-2 rotates, the discharge plate 30-4 will be driven to swing through the connecting arm 30-3. During the process of discharging sand and soil from the collecting cylinder 22, the discharge plate 30-4 can guide the discharged sand and soil to the designated position to avoid random accumulation of sand and soil, which not only keeps the construction site clean, but also provides convenience for subsequent sand and soil processing.

[0044] Specifically, one side of the rotating disk 30-2 is fixedly connected to the slide rail 30-5, the inner cavity of the slide rail 30-5 is slidably connected to the lifting rod 30-51, both sides of the lifting rod 30-51 are fixedly connected to the lifting frame 30-6, and an abutment block 30-7 is provided on one side of the bottom of the lifting frame 30-6. The abutment block 30-7 is located at the bottom of the lifting block 15, and the other side of the bottom of the lifting frame 30-6 is fixedly connected to the first spring 30-8, and the bottom of the first spring 30-8 is fixedly connected to the frame 30-1.

[0045] When the lifting block 15 rises to a certain position, the abutment block 30-7 will contact the lifting block 15. As the lifting block 15 continues to rise, it will drive the lifting frame 30-6 to rise. During this process, the first spring 30-8 will be deformed. At the same time, the rise of the lifting frame 30-6 will cause the lifting rod 30-51 to slide in the slide rail 30-5, thereby driving the rotating disk 30-2 to rotate. In this way, the rising movement of the lifting block 15 can be used to link the discharge plate 30-4 to swing, without the need for an additional power source. While simplifying the device structure, it also reduces the equipment cost.

[0046] When the lifting block 15 descends to prepare for the next drilling operation, the external force on the lifting frame 30-6 disappears. At this time, the first spring 30-8 recovers, driving the lifting frame 30-6 to move downward and reset, and then driving the lifting rod 30-51, the rotating disk 30-2 and other components to return to their initial state, so that the discharge plate 30-4 returns to the non-working position, preparing for the next discharge process.

[0047] Specifically, the top of the abutment block 30-7 is slidably connected to the abutment tube 30-9, the bottom of the inner cavity of the abutment tube 30-9 is fixedly connected to the second spring 30-10, the bottom of the second spring 30-10 is fixedly connected to the abutment block 30-7, and one side of the lifting frame 30-6 is fixedly connected to the positioning plate 30-11. A positioning groove 30-12 is provided on the surface of the mounting plate 13, and cooperates with the positioning plate 30-11.

[0048] Through the cooperation of the abutment tube 30-9 and the second spring 30-10, when the positioning plate 30-11 completes positioning in the positioning groove 30-12, the lifting block 15 continues to rise, causing the abutment tube 30-9 to slide on the abutment block 30-7. At this time, the second spring 30-10 begins to deform. This structure absorbs the excess thrust generated by the rise of the lifting block 15 through elastic deformation, so that the abutment block 30-7 no longer drives the lifting frame 30-6 to move, ensuring that the position of the discharge plate 30-4 remains unchanged. At the same time, the guide rod 26 can slide smoothly into the inclined guide rail 27, and drive the sealing plate 23 to move smoothly under the guidance of the inclined guide rail 27, opening the bottom of the collecting tube 22 for discharge. In this way, the position accuracy of the discharge plate 30-4 during discharge is guaranteed, allowing the sand and soil to be accurately discharged into the specified position, and avoiding excessive impact on structures such as the lifting frame 30-6, thereby maintaining the stability and reliability of the equipment operation.

[0049] Specifically, the adjusting member 31 includes a T-plate 31-1 fixedly connected to one side of the inner cavity of the base plate 12, a second motor 31-2 is fixedly connected to one side of the top of the T-plate 31-1, an output shaft of the second motor 31-2 is fixedly connected to a second screw rod 31-3, one side of the second screw rod 31-3 is rotatably connected to a second limit plate 31-4, the bottom of the second limit plate 31-4 is fixedly connected to the T-plate 31-1, a movable block 31-5 is threadedly connected to the surface of the second screw rod 31-3, a movable rod 31-6 is hinged to the top of the movable block 31-5, one side of the movable rod 31-6 is hinged to the mounting plate 13, and an adaption part 31-7 is provided on both sides of the mounting plate 13.

[0050] When the second motor 31-2 is working, it will drive the second screw rod 31-3 to rotate. The rotation of the second screw rod 31-3 will prompt the movable block 31-5 to move. The movement of the movable block 31-5 drives the mounting plate 13 to swing through the movable rod 31-6, thereby adjusting the angle of the drill rod 19-1 to meet the construction requirements of opening inclined holes.

[0051] It should be noted that there are limiting components on both sides of the movable block 31-5, which can ensure that the movable block 31-5 will move linearly instead of rotating under the action of the second screw rod 31-3.

[0052] Specifically, the adaptation part 31-7 includes a first piston rod 31-71 fixedly connected to one side of the mounting plate 13, one side of the first piston rod 31-71 is slidably connected to the first piston cylinder 31-72, the first piston cylinder 31-72 is fixedly connected to the top of the T-plate 31-1, both sides of the first piston cylinder 31-72 are connected to the first pipe 31-73, a first cavity 31-74 is opened on one side of the inner cavity of the discharge plate 30-4, one side of the first cavity 31-74 is slidably connected to the first extension plate 31-75, and one side of the first pipe 31-73 is connected to the first cavity 31-74.

[0053] When the mounting plate 13 swings, it drives the first piston rod 31-71 to slide in the first piston cylinder 31-72, so that the gas in the first piston cylinder 31-72 enters the first cavity 31-74 through the first pipe 31-73, and then pushes the first extension plate 31-75 to slide out of the first cavity 31-74, thereby increasing the discharge area on one side of the discharge plate 30-4. This structural design can automatically adjust the discharge area of the discharge plate 30-4 according to the swing angle of the mounting plate 13, ensuring that when the inclined hole is opened, the sand and soil discharged from the collecting cylinder 22 can accurately fall into the discharge plate 30-4, effectively improving the discharge efficiency.

[0054] Specifically, the other side of the mounting plate 13 is fixedly connected to the second piston rod 31-76, one side of the second piston rod 31-76 is slidably connected to the second piston cylinder 31-77, the first piston cylinder 31-72 is fixedly connected to the top of the base plate 12, both sides of the second piston cylinder 31-77 are connected to the second pipe 31-78, a second cavity 31-79 is opened on the other side of the inner cavity of the discharge plate 30-4, one side of the second cavity 31-79 is slidably connected to the second extension plate 31-80, and one side of the second pipe 31-78 is connected to the second cavity 31-79.

[0055] When the mounting plate 13 swings to the other side, it will drive the second piston rod 31-76 to slide in the second piston cylinder 31-77, so that the gas in the second piston cylinder 31-77 enters the second cavity 31-79 through the second pipe 31-78, pushing the second extension plate 31-80 to slide out of the second cavity 31-79, thereby increasing the discharge area on the other side of the discharge plate 30-4. Combined with the first piston rod 31-71, the first piston cylinder 31-72, the first pipe 31-73, the first cavity 31-74 and the first extension plate 31-75, this two-way adjustment structural design can fully adapt to the situation where the mounting plate 13 swings in different directions, further improving the discharge adaptability of the device when opening inclined holes.

[0056] Working principle: When performing drilling operations, first start the first motor 14-1, which drives the first screw rod 14-2 to rotate. Since the first screw rod 14-2 is connected to the lifting block 15 by a threaded connection, based on the principle of threaded transmission, the lifting block 15 will move downward along the through groove 16, thereby driving the upper cylinder 17, lower cylinder 18, drill rod 19-1 and conveying blade 19-2 fixedly connected to the lifting block 15 to descend together, so that the drill rod 19-1 reaches the position to be drilled. Then, the drive motor 19 starts to work, driving the drill rod 19-1 and the conveying blade 19-2 to rotate, thereby starting the drilling operation. The sand and soil generated during the drilling process are transported upward from the lower cylinder 18 to the upper cylinder 17 under the spiral push of the conveying blade 19-2. At the same time, the rotating plate 21 fixedly installed on the surface of the drill rod 19-1 will rotate with the drill rod 19-1. During the rotation process, the sand and soil transported to the upper cylinder 17 will be continuously pushed to the top of the collecting cylinder 22. When the sand and soil reach the top of the collecting cylinder 22, it will enter the collecting cylinder 22 for collection, effectively preventing the sand and soil from being directly discharged and accumulated outside the hole, keeping the construction site clean. When the drilling operation is completed, the first motor 14-1 drives the first screw 14-2 to rotate in the opposite direction, so that the lifting block 15 starts to rise, and the upper cylinder 17, the lower cylinder 18, the drill rod 19-1 and the conveying blade 19-2 will also rise synchronously. During the rising process, the sealing plate 23 will move upward together with the collecting cylinder 22. During this process, the guide rod 26 will slide in the vertical guide rail 28. When the lifting block 15 rises to a certain position, the abutment block 30-7 at its bottom will contact the lifting frame 30-6. As the lifting block 15 continues to rise, it will drive the lifting frame 30-6 to move upward. The rise of the lifting frame 30-6 will cause the lifting rod 30-51 to slide in the slide rail 30-5, thereby driving the rotating disk 30-2 and the connecting arm 30-3 to rotate, and swinging the discharge plate 30-4 to the bottom of the collecting cylinder 22. As the positioning plate 30-11 reaches the top of the positioning groove 30-12, the swinging process of the discharge plate 30-4 ends. At this time, the lifting block 15 continues to rise, the abutment cylinder 30-9 will slide on the abutment block 30-7, and the second spring 30-10 will be deformed. At the same time, the guide rod 26 will slide into the inclined guide rail 27. Under the guidance of the inclined guide rail 27, the guide rod 26 will drive the sealing plate 23 to move away from the lower cylinder 18, thereby opening the bottom of the collecting cylinder 22, and the sand is discharged from the bottom of the collecting cylinder 22 and guided and discharged by the discharge plate 30-4.

[0057] When the discharge is completed, the lifting block 15 descends, and the second spring 30-10 drives the abutting block 30-7 to return to the initial relative position for the next round of operation. During the movement of the blocking plate 23, the tooth plate 29-1 will be driven to move. Since the tooth plate 29-1 is engaged with the gear ring 29-2, the movement of the tooth plate 29-1 will drive the gear ring 29-2 and the scraper 29-3 to rotate, scraping off the sand and soil adhering to the inner wall of the collecting tube 22 to avoid blockage. When an inclined hole needs to be opened, the second motor 31-2 is started, which drives the second screw rod 31-3 to rotate. The movable block 31-5 is connected to the second screw rod 31-3 by a thread. The rotation of the second screw rod 31-3 will prompt the movable block 31-5 to move. The movement of the movable block 31-5 drives the mounting plate 13 to swing through the movable rod 31-6, thereby realizing the lifting block 15, the upper cylinder 17, the lower cylinder 18, the drill rod 19-1 and the conveying blade 19-2 to swing to one side to complete the angle adjustment. During the swinging process of the mounting plate 13, if it swings to one side, it will drive the first piston rod 31-71 to slide in the first piston cylinder 31-72, and the gas in the first piston cylinder 31-72 will be input into the first cavity 31-74 through the first pipe 31-73, pushing the first extension plate 31-75 to slide out of the first cavity 31-74, thereby increasing the discharge area on one side of the discharge plate 30-4. If the mounting plate 13 swings to the other side, it will drive the second piston rod 31-76 to slide in the second piston cylinder 31-77, and the gas in the second piston cylinder 31-77 will be input into the second cavity 31-79 through the second pipe 31-78, thereby pushing the second extension plate 31-80 to slide out of the second cavity 31-79, thereby increasing the discharge area on the other side of the discharge plate 30-4, thereby ensuring that when the inclined hole is opened, the sand and soil discharged from the collecting cylinder 22 can accurately fall into the discharge plate 30-4. Example 3

[0058] Reference Figure 1 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0059] Specifically, one side of the gantry 11 is fixedly connected to a support plate 13-1, the side of the support plate 13-1 close to the mounting plate 13 is fixedly connected to a support rail 13-2, the inner cavity of the support rail 13-2 is slidably connected to a support rod 13-3, and the side of the support rod 13-3 away from the support rail 13-2 is fixedly connected to the mounting plate 13.

[0060] When the mounting plate 13 swings, the support rod 13-3 will slide in the support rail 13-2, providing additional support force for the mounting plate 13, effectively enhancing the stability of the mounting plate 13. This support structure design can significantly reduce the shaking of the mounting plate 13 during the swinging process, ensure the stability of the drill rod 19-1 during operation, and at the same time extend the service life of the equipment and reduce the probability of damage to the equipment due to shaking.
