Description

Technical Field

[0001] This invention relates to the field of mining technology, specifically to a blasting drilling device and drilling method for mining. Background Technology

[0002] In mining operations, rock blasting is a common method. The quality of the blasting hole formation directly affects the blasting effect and construction safety. Specialized drilling equipment is usually required for pre-drilling. Currently, traditional mining blasting drilling devices generally suffer from problems in actual use, such as cumbersome drilling angle adjustment, unreliable fixing after adjustment, and easy deviation during operation. This makes it difficult to guarantee the verticality and positional accuracy of the borehole. In addition, the drilling process generates a large amount of dust with a wide diffusion range and poor collection effect, which not only seriously pollutes the construction site environment but also poses a significant threat to the health of operators. Summary of the Invention

[0005] As a preferred embodiment, the movable seat has an internal movable groove, a sliding block is slidably installed inside the movable groove, a threaded rod is threaded inside the sliding block, the left end of the threaded rod extends through to the outside of the movable seat and a first motor is installed thereon, and the right side of the sliding block is connected to the left end of the cross plate.

[0006] As a preferred embodiment, a second electric cylinder is installed on the left side of the top of the cross plate via a support pad, a first clamping block is installed at the output end of the second electric cylinder, the second clamping block is attached to the right surface of the rotating shaft, and the first clamping block is tightly attached to the left surface of the rotating shaft.

[0007] As a preferred embodiment, a shielding frame is fixedly installed on the upper end of the mobile frame, and the shielding frame covers the outside of the dust collection box. A reinforcing plate is installed on the upper right end of the mobile frame, and the upper end of the reinforcing plate is connected to the bottom of the dust pump.

[0008] As a preferred embodiment, a positioning bracket is installed at the lower right end of the reinforcing plate, and the right end of the positioning bracket is sleeved on the outside of the upper end of the suction pipe, with the suction end of the suction pipe being inclined to correspond to the surface of the drill rod.

[0009] As a preferred embodiment, a sleeve is installed on the left side of the bottom of the horizontal plate, a support spring is installed at the upper end of the inner cavity of the sleeve, a movable column is installed at the lower end of the support spring, the lower end of the movable column extends to the bottom of the sleeve and is fitted with a limiting guide plate, and the right end of the limiting guide plate is sleeved on the surface of the drill rod through a through groove.

[0010] As a preferred embodiment, the movable frame has symmetrically arranged movable slots at the front and back, and a movable block is slidably installed inside the movable slot. At the same time, the right end of the movable block is connected to the left side of the movable base.

[0011] As a preferred embodiment, an annular positioning ring is embedded on the right side of the top of the horizontal plate, and the annular positioning ring is sleeved on the outside of the rotating shaft and rotatably installed therewith.

[0012] As a preferred option, a blasting drilling method is used in mining, and the drilling method includes the following steps: Step 1: First, move the device to the designated position by pushing the handle and the casters. Then, start the hydraulic cylinder. The hydraulic cylinder will move the pad downwards to provide stable support for the device. Step 2: According to the drilling requirements, adjust the height of the moving seat by the first electric cylinder, drive the threaded rod to rotate by the first motor, and then drive the sliding block and the cross plate to move horizontally to adjust the horizontal position of the drill rod. By turning the handle, drive the rotating shaft, the second motor and the drill rod to rotate to adjust the drilling angle. Step 3: After adjustment, start the second electric cylinder.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, through the cooperation of a first electric cylinder, a moving seat, a first motor, a threaded rod, a sliding block, and a horizontal plate, enables the adjustment of the drill rod's position in the vertical and horizontal directions. Through the cooperation of a rotating shaft, a rotating handle, a second motor, a second electric cylinder, a first clamping block, and a second clamping block, the drilling angle of the drill rod can be adjusted and fixed to meet the drilling requirements of different angles. With the setting of a dust pump, a dust suction pipe, and a dust storage box, the dust generated during drilling can be sucked into the dust storage box in a timely manner, reducing dust diffusion, improving the working environment, and improving drilling accuracy and operational stability.

[0014] 2. This invention utilizes a movable groove, a sliding block, and a threaded connection with a threaded rod. A first motor drives the threaded rod to rotate, causing the sliding block to slide smoothly along the movable groove. This, in turn, allows for precise horizontal position adjustment of the horizontal plate and drill rod. The adjustment process is smooth and accurate, flexibly adapting to drilling needs at different locations in mining operations and effectively expanding the device's operating range. Simultaneously, a second electric cylinder mounted on the top of the horizontal plate via a support plate securely clamps and fixes the rotating shaft after the drill rod angle adjustment is complete. The clamping force is uniform and the fixing effect is reliable, effectively preventing loosening or displacement of the rotating shaft during drilling operations. This prevents angular deviations in the drill rod, ensuring the verticality and accuracy of the borehole, reducing drilling errors, improving the quality of blasting drilling operations, enhancing the overall operational stability and safety of the device, and reducing the operational difficulty for operators.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Secondly, the term "one embodiment" or "embodiment" as used 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 different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example 1:

[0019] Please see Figure 1 As shown, the present invention provides a blasting drilling device for mining, including a movable frame 1. Movable wheels 4 are symmetrically installed on the bottom of the movable frame 1. A push handle 5 is installed on the left side of the movable frame 1. Hydraulic cylinders 2 are installed on the bottom of the push handle 5 and on the right side of the movable frame 1. A pad 3 is installed at the output end of the hydraulic cylinder 2. A first electric cylinder 6 is installed on the upper right side of the movable frame 1 via a positioning plate. A movable seat 7 is installed at the output end of the first electric cylinder 6. A horizontal plate 12 is installed on the right side of the movable seat 7. A second motor 17 is installed on the right side of the bottom of the horizontal plate 12. A drill rod 18 is installed at the output end of the second motor 17. A rotating shaft 16 is embedded inside the right end of the horizontal plate 12. The lower end of the rotating shaft 16 is connected to the top of the second motor 17. A rotating handle 19 is installed on the upper end of the rotating shaft 16 via a connecting column. Dust suction pipes 23 are symmetrically installed on the front and back of the upper end of the drill rod 18. A dust suction pump 22 is connected to the upper end of the dust suction pipe 23. The dust outlet pipe of the dust suction pump 22 is connected to a dust storage box 21. Example 2:

[0020] Based on Embodiment 1, the present invention is as follows: Figure 4 As shown, the movable seat 7 has an internal movable groove 8, a sliding block 9 is slidably installed inside the movable groove 8, a threaded rod 11 is threaded inside the sliding block 9, the left end of the threaded rod 11 extends to the outside of the movable seat 7 and a first motor 10 is installed thereon, the right side of the sliding block 9 is connected to the left end of the horizontal plate 12; a second electric cylinder 13 is installed on the left side of the top of the horizontal plate 12 through a support pad, a first clamping block 14 is installed at the output end of the second electric cylinder 13, a second clamping block 15 is attached to the right surface of the rotating shaft 16, and the first clamping block 14 is tightly attached to the left surface of the rotating shaft 16.

[0021] Adopting such Figure 1The technical solution shown uses a movable groove 8 in conjunction with a sliding block 9 and a threaded connection with a threaded rod 11. A first motor 10 drives the threaded rod 11 to rotate, causing the sliding block 9 to slide smoothly along the movable groove 8. This, in turn, allows for precise horizontal adjustment of the horizontal plate 12 and the drill rod 18. The adjustment process is smooth and accurate, flexibly adapting to drilling needs at different locations in mining operations and effectively expanding the device's operating range. Simultaneously, a second electric cylinder 13, mounted on the top of the horizontal plate 12 via a support plate, can firmly clamp and fix the rotating shaft 16 after the drill rod 18 angle adjustment is completed. The clamping force is uniform and the fixing effect is reliable, effectively preventing the rotating shaft 16 from loosening or shifting during drilling operations. This prevents angular deviations in the drill rod 18, ensuring the verticality and accuracy of the drilling, reducing drilling errors, improving the quality of blasting drilling operations, enhancing the overall operational stability and safety of the device, and reducing the operational difficulty for operators.

[0022] Secondly, in the technical solution, a shielding frame 20 is fixedly installed on the upper end of the mobile frame 1, and the shielding frame 20 covers the outside of the dust collection box 21. A reinforcing plate 29 is installed on the upper right end of the mobile frame 1, and the upper end of the reinforcing plate 29 is connected to the bottom of the dust pump 22. A positioning bracket 24 is installed on the lower right end of the reinforcing plate 29, and the right end of the positioning bracket 24 is sleeved on the outside of the upper end of the suction pipe 23. The suction end of the suction pipe 23 is inclined and corresponds to the surface of the drill rod 18.

[0023] Its adoption is as follows Figure 1 The technical solution shown allows the shielding frame 20 to completely cover the outside of the dust collection box 21, effectively preventing gravel, dust, and debris generated during mining operations from colliding, wearing, or clogging the dust collection box 21, thus protecting the internal structure of the dust collection box 21. The suction end of the suction pipe 23 adopts an inclined design and precisely corresponds to the surface of the drill rod 18, which can maximize the alignment with the source of dust generated during drilling operations, improve dust adsorption efficiency, and quickly suck the dust generated by drilling the drill rod 18 into the suction pipe 23 and transport it to the dust collection box 21, reducing the impact of dust diffusion on the working environment and the health of operators. At the same time, the limiting function of the positioning bracket 24 can also ensure that the suction pipe 23 always maintains the optimal suction angle, ensuring a continuous and stable dust removal effect. Example 3:

[0024] The present invention is as follows Figures 1-5As shown, a sleeve 25 is installed on the left side of the bottom of the horizontal plate 12. A support spring 26 is installed at the upper end of the inner cavity of the sleeve 25. A movable column 27 is installed at the lower end of the support spring 26. The lower end of the movable column 27 extends to the lower part of the sleeve 25 and is fitted with a limiting guide plate 28. The right end of the limiting guide plate 28 is sleeved on the surface of the drill rod 18 through a through groove. The movable frame 1 has symmetrically opened movable grooves in the front and back, and a movable block is slidably installed in the movable groove. At the same time, the right end of the movable block is connected to the left side of the movable seat 7. An annular positioning ring is embedded on the right side of the top of the horizontal plate 12, and the annular positioning ring is sleeved on the outside of the rotating shaft 16 and rotatably installed therewith.

[0025] The above technical solution utilizes the sleeve 25, support spring 26, movable column 27, and limiting guide plate 28 in cooperation. The limiting guide plate 28 is sleeved on the surface of the drill rod 18 through a through groove, providing precise guidance and limiting for the drill rod 18. This prevents the drill rod 18 from shaking or shifting during high-speed drilling, ensuring the verticality and uniformity of the hole diameter and reducing drilling errors. Simultaneously, the support spring 26 has good elastic buffering properties, effectively absorbing the vibration generated during drilling and mitigating the impact of vibration on the drill rod 18, the cross plate 12, and the entire device. This protects the drill rod 18 from damage, extends its service life, and prevents vibration from affecting drilling accuracy. Furthermore, the movable column 27 can flexibly extend and retract with the up-and-down movement of the drill rod 18. This affects the normal progress of drilling operations; the moving groove inside the moving frame 1 cooperates with the sliding moving block to guide and limit the movement of the moving seat 7, ensuring that the moving seat 7 moves smoothly in a fixed direction under the drive of the first electric cylinder 6, avoiding tilting or deviation of the moving seat 7, further ensuring the accuracy of the horizontal and vertical adjustment of the drill rod 18, and improving the overall operational stability of the device; while the annular positioning ring at the top of the horizontal plate 12 rotatably cooperates with the rotating shaft 16, which can not only provide a stable support for the rotating shaft 16, preventing the rotating shaft 16 from shaking or deviating during the rotation adjustment angle or operation, ensuring the smoothness of the rotation of the rotating shaft 16, but also reduce the friction generated when the rotating shaft 16 rotates, reducing component wear.

[0026] A method for drilling holes in a mine is blasting, and the drilling method includes the following steps: Step 1: First, move the device to the designated position by pushing the handle 5 and the moving wheel 4, then start the hydraulic cylinder 2. The hydraulic cylinder 2 drives the pad 3 to move downward to provide stable support for the device. Step 2: According to the drilling requirements, adjust the height of the moving seat 7 by using the first electric cylinder 6, drive the threaded rod 11 to rotate by the first motor 10, thereby driving the sliding block 9 and the horizontal plate 12 to move horizontally, adjust the horizontal position of the drill rod 18, and drive the rotating shaft 16, the second motor 17 and the drill rod 18 to rotate by rotating the handle 19, thereby adjusting the drilling angle. Step 3: After adjustment, start the second electric cylinder 13. The second electric cylinder 13 drives the first clamping block 14 to move, and cooperates with the second clamping block 15 to clamp and fix the rotating shaft 16. Start the second motor 17, and the second motor 17 drives the drill rod 18 to rotate to perform drilling operations. Step 4: Simultaneously start the dust pump 22. The dust pump 22 sucks the dust generated during drilling into the dust storage box 21 through the dust suction pipe 23. The drill rod 18 is guided and limited by the sleeve 25, support spring 26, movable column 27 and limit guide plate 28 to improve drilling accuracy.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
