[0026] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.
[0027] like Figures 1-6 As shown, the open-pit mining drilling device provided in this embodiment includes a mobile chassis 1. A guide rail 2 is rotatably mounted on one end of the mobile chassis 1. A first hydraulic support 3, rotatably connected to the guide rail 2, is rotatably mounted on the top of the mobile chassis 1. A slide 4 is movably mounted on the side of the guide rail 2 away from the first hydraulic support 3. A first motor 5 is mounted on the top of the slide 4. The output end of the first motor 5 is connected to a drill rod 6. A drive mechanism 7 is provided on the guide rail 2 to drive the slide 4 to move up and down. A cleaning mechanism 8, sleeved on the outside of the drill rod 6, is installed at the bottom end of the guide rail 2. Through the cleaning mechanism 8, water can be sprayed for lubrication during drilling, facilitating drilling, preventing overheating of the drill rod, and reducing dust to prevent dust pollution. When drilling is completed and the drill rod is withdrawn, it can be cleaned without manual cleaning, making it simple, practical, and labor-saving.
[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the cleaning mechanism 8 includes a ring pipe 9 sleeved on the outside of the drill rod 6. Multiple nozzles 10 are evenly connected to the bottom of the ring pipe 9, and a water inlet pipe 11 is connected to the top of the ring pipe 9. A water pump 12 is installed on the top of the movable chassis 1. The output end of the water pump 12 is connected to the water inlet pipe 11 via a flexible hose 13. A brush 14 is installed on the inner side of the ring pipe 9, and the outlet of the nozzles 10 is inclined towards the drill rod 6. Through the arrangement of the ring pipe 9, nozzles 10, and water inlet pipe 11, during use, the water pump 12 supplies water through the flexible hose 13, and the outlet of the nozzles 10 is inclined towards the drill rod 6. This lubricates the drill rod 6 during drilling, and the dust generated during drilling is absorbed by the water mist. After drilling is completed, the drill rod 6 is pulled outwards, and the water sprayed from the nozzles 10 cleans the drill rod 6, while the brush 14 simultaneously scrubs it, improving cleaning efficiency.
[0029] In this embodiment, as Figure 1, Figure 2 and Figure 3 As shown, the ring tube 9 is connected to the guide rail 2 by bolts. A mounting plate 15 is fixedly connected to the bottom end of the guide rail 2. The mounting plate 15 has mounting holes 16 that mate with the bolts. A connecting plate 17 is fixedly connected to the outer wall of the ring tube 9. The connecting plate 17 has connecting holes 18 corresponding to the mounting holes 16. The bolts facilitate assembly, disassembly, and adjustment. During installation, the ring tube 9 is placed inside the mounting plate 15, aligning the mounting holes 16 with the connecting holes 18, and then secured with bolts.
[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, auxiliary support mechanisms 19 are connected to the four top corners of the mobile chassis 1. Each auxiliary support mechanism 19 includes a telescopic rod 20 mounted on the top of the mobile chassis 1. The extended end of the telescopic rod 20 is connected to a second hydraulic support 21, and the bottom end of the second hydraulic support 21 is connected to a support plate 22. By using the auxiliary support mechanisms 19, when drilling, pulling out the telescopic rod 20 activates the second hydraulic support 21 to provide auxiliary support, improving the stability during drilling.
[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the drive mechanism 7 includes a second motor 23 mounted on the top of the guide rail 2. The output end of the second motor 23 is connected to a lead screw 24, and a transmission component that cooperates with the lead screw 24 is connected to the slide 4. The second motor 23 drives the lead screw 24 to rotate, thereby driving the slide 4 to move.
[0032] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the open-pit mining drilling device provided in this embodiment is as follows:
[0033] Step 1: When drilling, pull out the telescopic rod 20 and activate the second hydraulic support 21 for auxiliary support;
[0034] Step 2: Start the first hydraulic support 3, rotate the guide rail 2 to the appropriate drilling angle, start the water pump 12 to spray, and at the same time start the first motor 5 and the second motor 23 to drill.
[0035] Step 3: After drilling is completed, when the drill rod 6 is pulled back, the water sprayed from the nozzle 10 cleans the drill rod 6, and the brush 14 scrubs it at the same time.
