[0002] Mist cannons are used for dust reduction at construction sites. Mist cannons, also known as air-blown sprayers, use the micron-sized particles produced by the spray to spray into the air, which can absorb dust particles of various sizes in the air faster and more effectively, thereby effectively reducing dust.

[0021] A second water pipe opening 311 is formed through the middle of the rotating shaft 31 , and a third water pipe opening 331 is formed through the middle of the gear plate 33 .

The cross-section of the first spiral hanger 22 is L-shaped, and an inner arc surface 221 is provided at the L-shaped angle of the first spiral hanger 22.

[0023] The adjustment seat 42 is composed of an adjustment base 421 and an adjustment top seat 422 which are hinged together. Two return springs 423 are used at the hinge between the adjustment base 421 and the adjustment top seat 422 to ensure that the adjustment top seat 422 always has an upward pulling force.

[0024] The linkage assembly 44 includes a connecting seat 441, and a first universal ball seat 442 is hinged at the lower end of the connecting seat 441, and a connecting rod 443 is connected to the lower end of the first universal ball seat 442, and a second universal ball seat 444 is arranged at the lower end of the connecting rod 443, and a hook seat 445 is arranged at the lower end of the second universal ball seat 444, and a ball seat 446 is obliquely arranged at the lower end of the hook seat 445, and the spherical surface of the ball seat 446 is movably opposed to the inner arc surface on the first spiral hanger 22.

[0026] Working principle: The working method is as follows: Before use, the dust reduction equipment needs to be moved to the central area where dust is generated more during construction on the project site, and a tap water pipe needs to be connected to the water tank group 1 for water addition.

[0027] When in use, first start the two dust reduction sprayers 43, and the water supply component 6 pumps water from the water tank body 11 to supply the two dust reduction sprayers 43 with water mist to reduce dust. At the same time, the bidirectional motor 34 drives the first dust reduction mechanism 4 and the second dust reduction mechanism 5 to rotate 180 degrees clockwise by driving the gear plate 33. In this process, the linkage component 44 will be pulled, and under the action of the two return springs 423, the adjustment top seat 422 always has an upward pull on the dust reduction sprayer 43, so that the spherical surface of the ball seat 446 and the inner arc surface of the first spiral hanger 22 are movable against each other for walking, and the walking mode is from the bottom position of the first spiral hanger 22 to the high position. The linkage allows the dust reduction sprayer 43 to synchronously swing upward at an angle of 110 degrees on the adjustment seat 42 during the water mist spraying process, thereby achieving dust reduction. When the dust sprayer 43 sprays water mist, it rotates half a circle clockwise horizontally and swings upward synchronously. After the driving component 3 completes the clockwise driving rotation, it is necessary to pause for 1 second to allow the rotator 24 to drive the vertical pipe 21 to rotate 90 degrees clockwise, so that the two dust reduction sprayers 43 are changed from a laterally symmetrical state to a longitudinally symmetrical state. After completion, the bidirectional motor 34 drives the first dust reduction mechanism 4 and the second dust reduction mechanism 5 to perform a counterclockwise reset rotation of 180 degrees through the driving gear plate 33. During this process, the dust reduction sprayer 43 will synchronously reset and swing downward at an angle of 110 degrees on the adjustment seat 42. Through the above operation, the two dust reduction sprayers 43 will spray water mist to reduce dust in a circular manner with the vertical pipe 21 as the center, and the sprayed water mist will form an upper and lower cross coverage.

[0028] It should be noted that the two dust reduction sprayers 43 mentioned above are responsible for processing half a circle of the project site respectively. In this way, after the dust reduction sprayer sprays a layer of water mist from bottom to top, before the water mist has a fault, the direction of the dust reduction sprayer 43 will be changed first, and then a layer of water mist will be sprayed from top to bottom to cross-cover with the previous layer of water mist, so that the dust in the half circle of the project site volume is wrapped and covered in two different directions, thereby realizing efficient spray dust reduction treatment.

[0029] When the water in the water tank body 11 is pumped down to a level sensed by the second water level sensor 13, the automatic solenoid valve 15 opens to let in tap water. When the water level rises to a level sensed by the second water level sensor 13, the automatic solenoid valve 15 closes to stop the water intake.
