Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The present invention provides three technical solutions, including the following embodiments:

[0030] Example 1

[0031] See also Figure 1-Figure 2 A dust suppression device for mining blasting includes a box body 1 made of high-strength metal material with good stability and durability. A mobile dust suppression mechanism 2 for suppressing dust near the box body 1 is provided on the top of the box body 1;

[0032] The mobile dust reduction mechanism 2 includes a fixed frame 21 fixed to the top of the box body 1, and two cross frames 22 are fixed on the top of the fixed frame 21. The tops of the two cross frames 22 are fixed with slide rails 23. The tops of the two cross frames 22 are provided with movable plates 24. The bottoms of the two movable plates 24 are fixed with sliders 25. The outer surfaces of the two slide rails 23 are slidably connected to the inner surfaces of the sliders 25. The sliders 25 are provided with slide grooves adapted to the slide rails 23. The inner surfaces of the slide grooves are slidably connected to the outer surfaces of the slide rails 23. Two mounting seats 26 are fixed on the top of the two mounting seats 26. Cylinders 27 are fixed on the tops of the two mounting seats 26. The two cylinders 27 are controlled by the same external switch and are electrically connected to the external power supply. The output ends of each cylinder 27 are fixed to one of the movable plates 24, and a fixed plate 28 is fixed between the tops of the two horizontal frames 22. The top of the fixed plate 28 is rotatably connected to a rotating plate 29 via a rotating shaft. Both sides of the top of the rotating plate 29 are rotatably connected to two rotating arms 210 via pins. One end of the two rotating arms 210 is rotatably connected to the top of the movable plate 24 via pins. A vertical pipe 211 is fixed to the top of the movable plate 24, and a nozzle 212 is installed on one side of the vertical pipe 211. There are multiple vertical pipes 211 and nozzles 212, and the multiple nozzles 212 are controlled by the same external switch and electrically connected to an external power supply. A blowing unit 3 is provided on the rotating plate 29 for blowing away the water mist sprayed by the nozzle 212.

[0033] By setting up the mobile dust suppression mechanism 2, the nozzle 212 can be moved back and forth, so that the water mist sprayed by the nozzle 212 can expand the range of dust suppression.

[0034] A water storage tank 5 is fixed on the bottom wall of the box body 1. Clean water is stored in the water storage tank 5. One side of the water storage tank 5 is connected to a water inlet pipe 6. One end of the water inlet pipe 6 passes through the box body 1 and extends to the outside of the box body 1. The top of the water inlet pipe 6 is connected to a liquid bucket 7. Clean water is poured into the liquid bucket 7 and enters the water storage tank 5 through the water inlet pipe 6 for storage. The arrangement of the water inlet pipe 6 and the liquid bucket 7 makes it convenient to replenish clean water.

[0035] A handle 9 is fixed on one side of the box 1, and four wheels 10 are installed on the box 1. The setting of the wheels can drive the entire dust reduction device to move. Pulling the handle 9 drives the wheels 10 to roll, and then drives the dust reduction device to move and reduce dust at the same time. The handle 9 and wheels 10 equipped with the box 1 enable the entire device to be easily moved to meet the needs of different work scenarios.

[0036] Example 2

[0037] Based on Example 1, see Figure 2 、 Figure 4 and Figure 5 As shown, the blowing unit 3 sucks in external air through the fan 31 and ejects it at high speed, while using the dust-proof sleeve 33 and the dust-proof net 39 to ensure the cleanliness of the air. The blowing unit 3 includes a fan 31 fixed on the rotating shaft of the rotating plate 29. The fan 31 is controlled by an external switch and is electrically connected to an external power supply. The air inlet of the fan 31 is connected to the air inlet pipe 32. The external air enters the fan 31 from the air inlet pipe 32, and the fan 31 compresses the air and then ejects it at high speed. The air inlet pipe 32 is threadedly connected with a dust-proof sleeve 33. The dust-proof sleeve 33 can be quickly disassembled and assembled on the air inlet pipe 32 through a threaded connection. The dust-proof sleeve 33 is open, and a dust-proof net is installed at the opening to prevent dust from entering the air inlet pipe 32 when the air is exhausted. The air outlet of the fan 31 is connected to a standpipe 34, and four connecting pipes 35 are fixed to the outer surface of the standpipe 34.

[0038] A ring tube 36 is fixed between the ends of the four connecting pipes 35 that are away from each other. Four through pipes 37 are connected to the four ring tubes 36. One end of the four through pipes 37 is connected to an air expansion hood 38. The air expansion hood 38 can expand the area where the wind is blown out. The design of the four air expansion hoods 38 ensures the uniform distribution of wind force and further expands the dust reduction range. Dustproof nets 39 are installed on the four air expansion hoods 38. The setting of the dustproof nets 39 can prevent dust from entering the air expansion hoods 38 when they are not in use.

[0039] By setting up the blowing unit 3 and utilizing the rotation of the rotating plate 29 on the mobile dust reduction mechanism 2, the air expansion hood 38 in the blowing unit 3 is synchronously driven to rotate. The air expansion hood 38 sends out the wind in the fan 31 and blows the water mist to the surroundings and farther, further expanding the range of dust reduction and improving the efficiency of dust reduction.

[0040] Example 3

[0041] Based on Example 2, see Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, a lifting cleaning component 4 for cleaning the dust net 39 is provided on the top of the fixed frame 21. The lifting cleaning component 4 includes a horizontal plate 41 fixed on the top of the fixed frame 21. An electric telescopic rod 42 is fixed on the top of the horizontal plate 41. The electric telescopic rod 42 is controlled by an external switch and is electrically connected to an external power supply.

[0042] A square plate 43 is fixed to the output end of the electric telescopic rod 42, and multiple bristles 44 are fixed to one side of the square plate 43. The bristles 44 are in contact with the dustproof net 39. When the air expansion cover 38 drives the dustproof net 39 to rotate, it comes into contact with the bristles and brushes off the dust on the dustproof net 39 while rotating.

[0043] Through the setting of the lifting cleaning component 4, when the dust net 39 needs to be cleaned, it is only necessary to start the electric telescopic rod 42 to drive the bristles 44 to rise. As the air expansion cover 38 rotates, the bristles 44 will easily brush away the dust on the dust net 39. After cleaning, close the electric telescopic rod 42 and the bristles 44 will automatically fall down without affecting the normal operation of the device.

[0044] A pumping assembly 8 is provided between the water tank 5 and the vertical pipes 211 on both sides. The pumping assembly 8 includes a U-shaped tube 81 connected to one side of the vertical pipe 211. One end of the U-shaped tube 81 passes through one side of the box body 1 and extends to the interior of the box body 1. The outer surface of the U-shaped tube 81 is slidingly connected to the inner surface of the box body 1. One end of the U-shaped tube 81 is connected to a horizontal tube 82. The bottom of the horizontal tube 82 is connected to a pumping pipe 83. The bottom end of the pumping pipe 83 is connected to a water pump 84. The water pump 84 is controlled by an external switch and is electrically connected to an external power supply. The water pump 84 is placed inside the water tank 5.

[0045] By setting the pumping assembly 8, the water in the water tank 5 is automatically pumped into the vertical pipe 211, ensuring that the nozzle 212 can continuously and stably spray water mist to perform continuous dust reduction treatment.

[0046] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0047] During operation, water is poured into the liquid bucket 7 and introduced into the water storage tank through the water inlet pipe 6. The water pump 84 is further started to pump water into the vertical pipe 211 through the water pumping pipe 83, the horizontal pipe 82 and the U-shaped pipe 81. The nozzle 212 is started to spray water in the form of water mist. The water mist combines with the dust in the air and eventually falls to the ground to achieve dust reduction. By starting the two cylinders 27, the cylinder 27 drives the movable plate 24 to move. At the same time, the movable plate 24 drives the two rotating arms 210 to rotate. The rotating arms 210 drive the rotating plate 29 to rotate. When the two movable plates 24 move in reverse, they drive the vertical pipe 211 and the nozzle 212 to move in reverse, thereby extending the sprayed water mist outward, increasing the range of the spray, and further starting the The fan 31 blows out air through the four air expansion hoods 38, and at the same time, the rotating plate 29 drives the blowing unit 3 to rotate. By starting and closing the two cylinders 27, a reciprocating cycle is realized to drive the nozzle 212 to move back and forth, and drive the four air expansion hoods 38 to rotate to discharge air. The blown wind is used to further disperse the water mist, so that the water mist is blown farther, thereby achieving dust reduction in a larger range. When it is necessary to clean the dust on the dustproof net 39, the fan 31 is turned off, and the electric telescopic rod 42 is started to drive the square plate 43 and the bristles 44 to move upward. When it moves to the highest point, the four air expansion hoods 38 rotate, so that the dustproof net 39 contacts the bristles 44 and cleans the dust on the dustproof net 39.

[0048] The above embodiments of the invention are described in detail, but the contents are only preferred embodiments of the invention and should not be considered to limit the scope of the invention. All equivalent changes and improvements made within the scope of the invention should still fall within the scope of the invention.
