[0023] When the spray device is used on the maintenance section of a municipal highway: first, move the mobile base 1 to the middle position of the maintenance section of the highway, then start the motor 15 in the adjustment component, the motor 15 can start to drive the worm 14 at the output end to rotate, the worm 14 is meshed with the worm wheel 13, so that the worm 14 can rotate while driving the worm wheel 13 to rotate, the worm wheel 13 is fixedly sleeved on the rotation of the screw rod 9, and the screw rod 9 can drive the nut 11 on the positive and negative thread segments at both ends to move, because one side of the nut 11 is connected to the limit assembly, the nut 11 can move toward or in the opposite direction when the screw rod 9 rotates, when it is necessary to spray and maintain the narrow section , so that the nuts 11 move toward each other, the angle between the nozzles 3 can be reduced by pulling the hinge shaft 23, so that the end of the nozzle 3 away from the connecting block 12 moves toward the middle of the screw rod 9. At this time, the distance between the two nozzles 3 away from the end of the connecting block 12 can be reduced, so that the nozzle 3 is located within the width range of the maintenance section, and the nozzle 3 can be used in a narrow section; when it is necessary to spray and maintain a wide section, the nuts 11 are moved in opposite directions, and the nuts 11 pull the angle between the nozzles 3 through the hinge shaft 23 to increase, so that the end of the nozzle 3 away from the connecting block 12 moves in the direction away from the worm gear 13. At this time, the two nozzles 3 can be deployed, and the nozzle 3 can be deployed for spraying on a wide road.

[0024] After the nozzle 3 is adjusted, the motor 15 is stopped and the water pump 7 is started. The water pump 7 can transport the water in the water tank 2 to the water supply pipe 6 through the water inlet pipe 8, and then enter the U-shaped hose 5 from the water supply pipe 6, and finally enter the nozzle 3 from the U-shaped hose 5, and be sprayed out from the nozzle 4 connected to the nozzle 3, so as to achieve the effect of spraying the maintenance section, prevent cracks in the road surface, and improve the safety of road surface maintenance.

[0025] The device has a simple structure and is convenient for staff to operate. By adding a spray component and an adjustment component, the angle between the nozzles 3 can be adjusted, and the nozzles 3 can be unfolded and folded to be suitable for maintenance sections of different widths, thereby avoiding the nozzle 3 from being too long and causing water to be sprayed outside the maintenance section, reducing the waste of water resources while improving the cleanliness of the environment around the maintenance section and facilitating the passage of pedestrians.
