Description

Technical Field

[0001] This utility model relates to the technical field of dust suppression in mines, and in particular to a dust suppression device for mines. Background Technology

[0002] Dust suppression in mines refers to taking a series of measures to reduce dust emissions and diffusion during mining operations, so as to reduce the adverse effects on the environment and human health. An existing open-pit mine dust suppression device (announcement number: CN220929455U) has an electric push rod and motor that ensures that the water mist cannon will not change arbitrarily after being adjusted to an appropriate angle. Turning the rocker arm can retract or release the water pipe.

[0003] Although the angle of the water mist cannon can be adjusted using an electric push rod and motor, allowing it to perform water mist dust suppression operations in different directions, the dust suppression range after each adjustment is limited, resulting in relatively low operational flexibility. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dust suppression device for mines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dust suppression device for mines includes a water tank, a frame rotatably connected to the water tank, water mist cannons at one and the other ends of the frame, a through groove on the frame, a sliding rod slidably connected to the through groove, a sleeve slidably connected to the outer wall of the sliding rod, the sleeve being fixedly connected to the water tank, the other end of the sliding rod being slidably connected to an annular groove on a turntable, a motor installed at the water tank, a base fixedly connected to the output end of the motor, a screw rotatably connected to the base, the screw being threadedly connected to the turntable, and the turntable being slidably connected to the base.

[0007] Preferably, both sets of water mist cannons are rotatably connected to the frame, and one end of each set of water mist cannons is fixedly connected to a worm gear. Two sets of worms are rotatably connected to the frame, and the two sets of worms are respectively meshed with the corresponding worm gears.

[0008] Preferably, the water tank is equipped with two sets of pumps, and each set of pumps has a pipe connected to its output end. The two sets of pipes are respectively connected to the two sets of water mist cannons.

[0009] Preferably, a valve body is installed at the water tank.

[0010] Preferably, a first handle is fixedly connected to the screw.

[0011] Preferably, a second handle is fixedly connected to both sets of worm gears.

[0012] Preferably, both sets of tubes are telescopic flexible tubes.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the coordination between the frame, water mist cannon, through groove, slide rod, sleeve, motor, screw, base and turntable, the screw drives the turntable to move laterally at the base. At this time, with the help of the motor to drive the base to rotate, the turntable can rotate eccentrically to different degrees. In turn, the turntable can pull the slide rod to move its stroke. The slide rod can cooperate with the through groove to drive the frame to drive the two sets of water mist cannons to perform reciprocating swing operation with different strokes. The two sets of water mist cannons can perform water spraying operation with different ranges, which can expand or reduce the water spraying dust suppression range. It has relatively high operational flexibility for dust suppression in mines.

[0015] 2. By coordinating the worm gear, worm wheel, and water mist cannon, the worm gear drives the worm wheel to adjust the angle of the water mist cannon, and can further adjust the spray range of the water mist cannon to ensure the dust suppression effect in the mine.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 A dust suppression device for mines includes a water tank 1, a frame 2 rotatably connected to the water tank 1, and water mist cannons 3 at one and the other ends of the frame 2. The model of the water mist cannons 3 is selected according to actual working requirements. A through groove 4 is opened in the frame 2, and a sliding rod 5 is slidably connected to the through groove 4. A sleeve 6 is slidably connected to the outer wall of the sliding rod 5, allowing the sliding rod 5 to slide within the sleeve 6. The sleeve 6 is fixed to the water tank 1. The other end of the sliding rod 5 is slidably connected to an annular groove in a turntable 10. When the turntable 10 rotates with the base 8, it can push the sliding rod 5 to move, thereby allowing the sliding rod 5 to cooperate with the through groove 4 to drive the frame 2 to swing the two sets of water mist cannons 3 in a fan-shaped reciprocating motion. The water tank 1 is equipped with a motor 7. The model of motor 7 is selected according to the actual working requirements. The output end of motor 7 is fixedly connected to a base 8. A screw 9 is rotatably connected to the base 8. The screw 9 is threadedly connected to a turntable 10. The turntable 10 is slidably connected to the base 8. The screw 9 drives the turntable 10 to adjust its position. When the motor 7 drives the base 8 to rotate, the turntable 10 can be rotated eccentrically to different degrees. The turntable 10 can then push the slide bar 5 to move at different strokes. The slide bar 5, in conjunction with the through groove 4, can drive the frame 2 to drive the two sets of water mist cannons 3 to swing back and forth in a fan shape at different strokes, which can expand or shrink the spray dust suppression range.

[0024] In this embodiment, both sets of water mist cannons 3 are rotatably connected to the frame 2. A worm gear 11 is fixedly connected to one end of each set of water mist cannons 3. Two sets of worms 12 are rotatably connected to the frame 2, and each set of worms 12 meshes with a corresponding worm gear 11. The transmission between the worms 12 and the worm gears 11 allows adjustment of the placement angle of the water mist cannons 3, further altering the spray range for dust suppression. Two sets of pump bodies 13 are installed inside the water tank 1. The model of the pump body 13 is selected according to actual working requirements. Each of the 13 output ends is connected to a pipe body 14. The two sets of pipe bodies 14 are respectively connected to the two sets of water mist cannons 3. A valve body 15 is installed at the water tank 1. The valve body 15 is used to discharge the water in the water tank 1. A first handle 16 is fixed to the screw 9. A second handle 17 is fixed to each of the two sets of worm gears 12. Both sets of pipe bodies 14 are telescopic hoses, so that when the frame 2 drives the two sets of water mist cannons 3 to swing back and forth in a fan shape, the pump body 13 can supply water to the water mist cannons 3 relatively stably with the help of the pipe body 14.

[0025] The working principle of this embodiment is as follows: When in use, water is injected into the water tank 1. After injection, the water mist cannon 3 is adjusted in angle according to the actual dust suppression range of the water mist cannon 3, using the transmission of the second handle 17, worm gear 12 and worm wheel 11. After the angle is adjusted, the first handle 16 drives the screw 9 to rotate, adjusting the position of the turntable 10. After adjustment, the motor 7 and the pump body 13 are connected to an external power source. The motor 7 will drive the base 8 to rotate the turntable 10 eccentrically to different degrees. The turntable 10 can then drive the slide bar 5 to move at different strokes. The slide bar 5 will then drive the frame 2 to move the two sets of water mist cannons 3 to swing back and forth in a fan shape at different strokes through the through groove 4. Thus, the two sets of water mist cannons 3 will spray water to suppress dust in the mine at different ranges.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
