7. The dust suppression equipment for municipal highway construction according to claim 1, characterized in that: The bottom of the spray barrel (11) is fixedly connected to a slide rail (617), the top end of the slide rod (615) is located inside the slide rail (617), the slide rod (615) is slidably connected to the slide rail (617), and a plurality of spray heads (618) are evenly arranged, and the spray heads (618) are distributed in an array.

8. The dust suppression equipment for municipal highway construction according to claim 1, characterized in that: A water inlet (12) is installed on the other side of the top of the water tank (4), and a water outlet (13) is installed on one side of the water tank (4).

9. A method for using a dust suppression device for municipal highway construction, using the dust suppression device for municipal highway construction as claimed in any one of claims 1 to 8, the steps of the method for using are as follows: Step 1: By starting the pressure pump (7), the pressure pump (7) draws water from the water tank (4) through the water pumping pipe (8) and inputs it into the drainage pipe (9), a part of the water is input into the connecting pipe (52), and the other part is input into the spray barrel (11) through the telescopic pipe (10), and is sprayed out by the spray head (618) to reduce dust. The regulating valve (53) can be adjusted to control the size of the water flow sprayed out of the connecting pipe (52); Step 2: The water flow sprayed from the connecting pipe (52) impacts the auxiliary impeller (55), which can drive the auxiliary impeller (55) to rotate. The auxiliary impeller (55) drives the rotating shaft (54) to rotate. The water that has impacted the auxiliary impeller (55) flows into the water tank (4) through the return pipe (56) to be reused. The one-way valve (57) can be unidirectional, thereby preventing the water inside the water tank (4) from flowing back into the upper box body (51), thereby achieving a cyclic impact on the auxiliary impeller (55), making it easier for the auxiliary impeller (55) to drive the rotating shaft (54) to rotate and for the subsequent swinging of the spray barrel (11) for spraying; Step 3: When the rotating shaft (54) rotates, the rotating shaft (54) drives the cam (61) to rotate, the cam (61) drives the internal slide groove (65) to rotate, the slider (66) slides inside the slide groove (65), the side plate (62) limits the rack (64), so that the rack (64) and the slider (66) move back and forth in a straight line, the slider (66) moves and drives the gear (68) to rotate back and forth, the gear (68) drives the top block (69) and the side plate (610) to rotate, the side plate (610) drives the spray barrel (11) to rotate, so that the spray barrel (11) swings back and forth horizontally, the spray barrel (11) drives the spray head (618) to swing back and forth horizontally, and the spray barrel (11) drives the slide bar (615) to slide in the adapting groove (614); Step 4: The gear (68) drives the screw rod (67) to rotate back and forth, and the limit rod (613) limits the sector plate (612) and the adjustment sleeve (611), so that the adjustment sleeve (611) moves back and forth up and down. The movement of the adjustment sleeve (611) drives the sector plate (612) to move up and down. The rise and fall of the sector plate (612) drives the slide bar (615) to move, so that the slide bar (615) lifts and pulls down the spray barrel (11). The slide rail (617) assists the rise and fall of the slide bar (615), thereby realizing the vertical swing of the spray barrel (11) with the end close to the top block (69) as the axis.
