[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This drilling device for open-pit blasting involves a main bevel gear, a secondary bevel gear, a hollow rod, a fixed sleeve, and a brush plate. The drive motor rotates the secondary bevel gear, which meshes with the main and secondary bevel gears, causing the drill rod and hollow rod to rotate synchronously in opposite directions. Upon completion of drilling, a hydraulic push rod pulls the protective cover, causing the hollow rod and drill rod to slide within the fixed sleeve. Simultaneously, the hollow rod, via a limit bar, rotates the fixed sleeve, causing one end of the fixed sleeve and the brush plate below to rotate synchronously.

Detailed Implementation

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figure 1-4 As shown, this utility model provides a technical solution: a drilling device for open-pit blasting construction, including an installation cylinder 1 and a dust collection cylinder 2. A fixing hoop 3 is connected to the installation cylinder 1, and the installation cylinder 1 is fixedly connected to the dust collection cylinder 2 through the fixing hoop 3. A working motor 27 is fixedly installed above the dust collection cylinder 2. A drive wheel 28 is installed on the output shaft of the working motor 27. A transmission belt 29 is installed on both the drive wheel 28 and the rotating wheel 18. Dust is collected through the dust collection cylinder 2, and the knocking plate 22 can slide up and down through the cooperation of the drive wheel 28, the transmission belt 29 and the rotating wheel 18, thereby completing the knocking work of the filter screen 17 and realizing the cleaning of the attached dust.

[0015] A groove 4 is provided on one side of the mounting cylinder 1, and a connecting pipe 5 is connected to one side of the mounting cylinder 1. An air pump 23 is fixedly installed on one side of the dust collection cylinder 2 and is connected to the air pump 23 through a pipe. One end of the connecting pipe 5 is threadedly connected to the bottom of the dust collection cylinder 2 through a threaded joint. A corrugated cover 24 is connected to the bottom of the mounting cylinder 1. The connecting pipe 5 is threadedly connected to the dust collection cylinder 2, which allows the staff to easily turn and disassemble it, thereby realizing the emptying and cleaning of dust.

[0016] A hydraulic push rod 6 is fixedly installed above the mounting cylinder 1. A protective cover 7 is connected to the movable end of the hydraulic push rod 6. A fixed plate 8 is connected to one side of the protective cover 7. A drill rod 9 is rotatably connected inside the protective cover 7 via a bearing. A main bevel gear 10 is connected to the drill rod 9. A hollow rod 11 is rotatably connected below the protective cover 7 via a bearing. A secondary bevel gear 12 is connected to one end of the hollow rod 11. A fixed sleeve 13 is slidably connected to the hollow rod 11. Limiting strips 25 are connected to both sides of the hollow rod 11. Limiting grooves 26 are opened on the inner walls of both sides of the fixed sleeve 13. The limiting strips 25 slide in the limiting grooves 26. The fixed sleeve 13 is rotatably connected to the mounting cylinder 1 via a bearing. The sliding of the limiting strips 25 in the limiting grooves 26 allows the hollow rod 11 to slide smoothly in the fixed sleeve 13 and enables the hollow rod 11 to synchronously drive the fixed sleeve 13 to rotate.

[0017] A brush plate 14 is connected to the inner side and the bottom of one end of the fixed sleeve 13. A drive motor 15 is fixedly installed on the fixed plate 8. The output shaft of the drive motor 15 passes through the protective cover 7 and is connected to the secondary bevel gear 16. It rotates with the protective cover 7 through the bearing. The two sides of the secondary bevel gear 16 mesh with the main bevel gear 10 and the auxiliary bevel gear 12 respectively and are all set inside the protective cover 7. The drill rod 9 passes through the hollow rod 11 and the auxiliary bevel gear 12. The protective cover 7 can cover and protect the main bevel gear 10, the auxiliary bevel gear 12 and the secondary bevel gear 16 to prevent rock and soil particles from hitting and damaging the main bevel gear 10, the auxiliary bevel gear 12 and the secondary bevel gear 16.

[0018] A filter screen 17 is connected inside the dust collection cylinder 2. A rotating wheel 18 is rotatably connected above the dust collection cylinder 2 via a bearing. Multiple wedge-shaped blocks 19 are connected at equal intervals above the rotating wheel 18. A sliding rod 20 is slidably connected through the rotating wheel 18. Flange rods 21 are connected to both sides of one end of the sliding rod 20. A striking plate 22 is connected to the other end of the sliding rod 20. A spring 30 is sleeved on the sliding rod 20. One end of the spring 30 is fixedly connected to the sliding rod 20, and the other end of the spring 30 is fixedly connected to the inner wall of the dust collection cylinder 2. The fixing plate 8 slides in the sliding groove 4. The filter screen 17 can filter and block dust, preventing dust from entering the air pump 23. The striking plate 22 can strike the filter screen 17 by sliding the sliding rod 20 up and down, preventing the attached dust from clogging the filter screen 17.

[0019] The working principle of this utility model is as follows: During drilling, both the brush plate 14 and the corrugated cover 24 are in contact with the ground. Then, the drive motor 15 is started to rotate the secondary bevel gear 16. The meshing of the secondary bevel gear 16 with the main bevel gear 10 and the auxiliary bevel gear 12 causes the drill rod 9 and the hollow rod 11 to rotate synchronously in opposite directions. The hydraulic push rod 6 then pushes the protective cover 7, causing the drill rod 9 and the hollow rod 11 to slide into the fixed sleeve 13. The extension of the drill rod 9 completes the drilling. Afterwards, the hydraulic push rod 6 pulls the protective cover 7, allowing the drill rod 9 to retract into the fixed sleeve 13. Simultaneously, the hollow rod 11, through the limit strip 25, drives the fixed sleeve 13 to rotate, causing one end of the fixed sleeve 13 to rotate synchronously with the brush plate 14 below, thus achieving… The drill rod 9 is cleaned to ensure the hole is clear. While drilling and cleaning, the air pump 23 can extract the air from the dust collection cylinder 2, and the connecting pipe 5 can extract the air and dust from the corrugated cover 24. The dust flows into the dust collection cylinder 2 and is filtered and blocked by the filter screen 17. The working motor 27 will rotate the drive wheel 28 and drive the rotating wheel 18 to rotate through the transmission belt 29. This allows the wedge block 19 to push the flange rod 21 and make the slide rod 20 slide upward, thereby driving the striking plate 22 and the compression spring 30. When the flange rod 21 disengages from the wedge block 19, the spring 30 rebounds, causing the slide rod 20 and the striking plate 22 to move down and strike the filter screen 17, thereby realizing the automatic cleaning of the filter screen 17.
