[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a dust reduction device for controlling coal yard dust includes an outer shell 1. The bottom end of the outer shell 1 is fixedly connected with a rotating plate 10 through a bracket mechanism. The outer periphery of the rotating plate 10 is rotatably installed with a base 11 in contact with the ground. A reciprocating driving mechanism is installed on the inner wall of the base 11, and the reciprocating driving mechanism is used to drive the rotating plate 10 to perform a reciprocating arc motion; the bracket mechanism is used to adjust the angle of the outer shell 1. The bracket mechanism includes a pushing component and a rotating component. The rotating component includes a rotating seat 6 fixedly connected to the lower part of the outer wall of the outer shell 1. The outside of the rotating seat 6 is rotatably installed with a fixed seat 7, and the bottom end of the fixed seat 7 is fixedly connected to the top of the rotating plate 10.

[0021] In this embodiment: when using this device, connect the device to a high-pressure water pump, and connect the water pump to a water source through a pipeline. Then start the reciprocating driving mechanism. The reciprocating driving mechanism drives the outer shell 1 to reciprocate in the arc direction, and synchronously start the bracket mechanism to drive the angle of the outer shell 1 to be adjusted, so as to facilitate better dust reduction.

[0022] Please pay special attention to Figure 1 , Figure 2 and Figure 4 , the pushing component includes a connecting seat 8 fixedly connected to the top of the rotating plate 10. The inside of the connecting seat 8 is rotatably installed with an electric push cylinder 9. The output end of the electric push cylinder 9 is connected with a connecting head 12. A slide shaft 19 is rotatably installed between the two vertical plates of the connecting head 12. A chute 13 for the slide shaft 19 to slide is opened on the outside of the outer shell 1.

[0023] In this embodiment: by starting the electric push cylinder 9, the electric push cylinder 9 pushes the connecting head 12 to move. The connecting head 12 drives the slide shaft 19 to move along the chute 13. The outer shell 1 under the thrust drives the rotating seat 6 and the fixed seat 7 to rotate, so as to achieve the purpose of adjusting the outer shell 1.

[0024] Please refer with emphasis to Figure 3 Figure 3 , the reciprocating drive mechanism includes a fixing plate 15 fixedly connected to the middle section of the inner wall of the base 11. A rotating motor 14 is installed at the bottom end of the fixing plate 15. The output shaft of the rotating motor 14 penetrates above the fixing plate 15. At the top of the rotating motor 14, two meshing drive gears 16 are rotatably installed through a rotating shaft. The output end of the fixing plate 15 is connected to the rotating shaft of one of the drive gears 16 through a coupling. At the top ends of the outer walls of the two rotating shafts, half gears 17 are press-fitted. A rotating gear 18 is arranged between the two half gears 17. The rotating gear 18 is fixedly connected to the center position at the bottom end of the rotating plate 10. Only one of the two half gears 17 meshes with the rotating gear 18 during the rotation state all the time.

[0025] In this embodiment: By starting the rotating motor 14, the rotating motor 14 drives the connected drive gear 16 to rotate. This drive gear 16 drives the other drive gear 16 to rotate synchronously in the opposite direction. At this time, the two half gears 17 rotate synchronously, and the two half gears 17 rotate in opposite directions. When one of the half gears 17 meshes with the rotating gear 18, the other half gear 17 is in a separated state from the rotating gear 18. Therefore, when the two half gears 17 respectively mesh with the rotating gear 18, the rotating directions of the rotating gear 18 are opposite. The rotating gear 18 can drive the rotating plate 10 to drive the housing 1 to move reciprocally in the arc direction.

[0026] Please refer with emphasis to Figure 1 and Figure 2 Figure 2 , an air suction fan 2 is installed at the tail end of the inner wall of the housing 1. A hollow-structured annular pipe 3 is fixedly installed at the head end of the housing 1. A water inlet pipe 5 connected to the annular pipe 3 is installed above the housing 1. The water inlet pipe 5 is communicated with the inner cavity of the annular pipe 3. A plurality of nozzles 4 distributed at equal intervals in a ring shape are fixedly connected to the outer wall of the annular pipe 3. The inner cavity of the nozzle 4 is communicated with the inner cavity of the annular pipe 3.

[0027] In this embodiment: By starting the high-pressure water pump, after the high-pressure water pump sucks water into the water inlet pipe 5, the water enters the annular pipe 3 through the water inlet pipe 5. The water body then sprays out from the nozzles 4 through the annular pipe 3. The sprayed water mist scatters outward under the blowing force of the air suction fan 2, so as to come into contact with the pulverized coal in the air and sediment the pulverized coal.

[0028] The above-mentioned is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
