[0026] like Figure 1 and Figure 2 As shown, the present application provides an open-pit coal mine drilling device, including a mobile frame 1, on which is provided a stabilizing component 2 for stabilizing the mobile frame 1, a drilling component 3 for mining and drilling in coal mines, a first adjusting component 4 for driving the drilling component 3 to move up and down, a protective component 5 for preventing the spread of flying rocks and dust generated during the operation of the open-pit coal mine drilling device, and a second adjusting component 6 for driving the protective component 5 to move up and down, the protective component 5 includes a protective cover 51 and a baffle plate 52, the baffle plate 52 is movably sleeved on the lower part of the protective cover 51, and a group of elastic adjusting components 7 are symmetrically provided between the protective cover 51 and the baffle plate 52, the protective cover 51 and the baffle plate 52 in the protective component 5 can effectively prevent the spread of flying rocks and dust generated during the operation of the open-pit coal mine drilling device, which greatly reduces the risk of injury to operators and surrounding equipment caused by flying rocks, and at the same time reduces the pollution of dust to the environment and the harm to the health of operators, and the elastic adjusting component 7 can make the baffle plate 52 better adapt to the working surface and improve the protection effect.
[0027] like Figure 1 and Figure 2As shown, the elastic adjustment component 7 includes a first connecting ear 71, a connecting rod 72, a spring 73 and a second connecting ear 74. The first connecting ear 71 is fixed to one side of the protective cover 51, and the second connecting ear 74 is located below the first connecting ear 71 and fixed to the baffle plate 52. The upper end of the connecting rod 72 is fixed to the bottom of the first connecting ear 71, and the lower end of the connecting rod 72 is movable through the second connecting ear 74. The lower end of the connecting rod 72 is provided with an anti-fall limit block 721, and the spring 73 is sleeved on the connecting rod 72 and located between the first connecting ear 71 and the second connecting ear 74. The setting of the spring 73 enables the baffle plate 52 to move up and down flexibly within a certain range to adapt to different terrain height changes. When vibrations are generated during operation, the baffle plate 52 can automatically adjust its position through the extension and contraction of the spring 73, always maintaining a good fit with the ground, thereby improving the adaptability of the protective component 5 to the working environment.
[0028] like Figure 1 and Figure 2 As shown, the first adjusting assembly 4 includes a first hydraulic cylinder 41, a first guide rod 42, a second guide rod 43 and a movable plate 44. The first hydraulic cylinder 41 is fixed on the movable frame 1, and the first guide rod 42 and the second guide rod 43 are symmetrically fixed on the movable frame 1. The movable plate 44 is movably sleeved on the first guide rod 42 and the second guide rod 43. The telescopic rod of the first hydraulic cylinder 41 is fixedly connected to the top of the movable plate 44. The drilling assembly 3 is located on the movable plate 44. The first hydraulic cylinder 41 can provide stable power and control the up and down movement of the movable plate 44 through the telescopic rod. The adjustment of the height of the drilling assembly 3 is achieved. In the actual mining of open-pit coal mines, the height position of the drill hole can be flexibly adjusted according to different coal seam thicknesses, terrain undulations and mining requirements to ensure the accuracy and effectiveness of drilling and improve the quality and efficiency of coal mining. The movable plate 44 is movably sleeved on the first guide rod 42 and the second guide rod 43, providing precise guidance for the up and down movement of the movable plate 44, thereby ensuring the stability and linearity of the movable plate 44 during the lifting process. This helps the drilling assembly 3 to always maintain vertical drilling, avoid drilling deviation due to offset, and improve drilling accuracy.
[0029] like Figure 2As shown, the drilling assembly 3 includes a drilling machine 31 and a drill bit 32. The drilling machine 31 is fixed to the bottom of the movable plate 44. The upper end of the drill bit 32 is connected to the output end of the drilling machine 31, and the lower end of the drill bit 32 extends into the protective cover 51. The drilling machine 31 is fixed to the bottom of the movable plate 44. With the help of the stability of the movable plate 44, it can maintain a relatively fixed position during operation to reduce drilling errors caused by shaking. Specifically, the first hydraulic cylinder 41 drives the first guide rod 42 and the second guide rod 43 of the movable plate 44 to move downward, and the movable plate 44 drives the drilling machine 31 to move downward. The drilling machine 31 drives the drill bit 32 to move downward to drill the coal mine rock layer. The flying rocks and dust generated are blocked by the protective assembly 5 to prevent flying rocks from injuring people and dust from spreading.
[0030] like Figure 1 and Figure 2 As shown, the second adjustment component 6 includes a second hydraulic cylinder 61, a guide column 62 and a connecting plate 63. The second hydraulic cylinder 61 and the guide column 62 are both fixed on the mobile frame 1. The top of the connecting plate 63 is fixedly connected to the telescopic rod of the second hydraulic cylinder 61. The connecting plate 63 is movably sleeved on the guide column 62. The protective cover 51 is fixed to the bottom of the connecting plate 63. The up and down movement of the connecting plate 63 can be controlled by the extension and retraction of the telescopic rod of the second hydraulic cylinder 61, thereby driving the protective cover 51 to adjust its height. In open-pit coal mine drilling operations, the height of the protective cover 51 can be flexibly adjusted according to different drilling depths, flying rocks and dust generation conditions to ensure that it can effectively block flying rocks and dust, thereby improving the targetedness and effectiveness of protection.
[0031] like Figure 1 and Figure 2 As shown, universal wheels 8 are provided at the bottom of the mobile frame 1. The universal wheels 8 enable the open-pit coal mine drilling device to be flexibly moved within the working site, making it convenient for the operator to quickly transfer the equipment to different drilling positions.
[0032] like Figure 1 and Figure 2 As shown, there are two stabilizing components 2, which are symmetrically arranged. The stabilizing components 2 include a bolt 21 and a stabilizing plate 22. The bolt 21 passes through the mobile frame 1 and is threadedly connected to the mobile frame 1. The stabilizing plate 22 is fixed to the lower end of the bolt 21. By rotating the bolt 21, the height of the stabilizing plate 22 can be adjusted to make it in close contact with the ground, thereby increasing the friction and supporting force between the equipment and the ground and ensuring stable operation of the equipment.
[0033] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
