Therefore, timely and effective road maintenance is a key link to ensure road safety, comfort, and smooth traffic. This includes cleaning and moisturizing roads and weeds. Road maintenance requires the use of sprinklers, but current sprinklers still have the following shortcomings when used:

[0003] The road maintenance nozzles require the help of motors to achieve the swinging effect, which increases the cost and maintenance frequency of the nozzle drive. In addition, the swing angle of the nozzle is limited to swinging in the same direction, which easily leads to uneven spraying at the road maintenance location, reducing the practicality of road spraying in the road maintenance device.

[0039] Example 3, based on Example 1, refer to Figures 1 to 7 As shown, a water sprayer and a herbicide sprayer are needed.

[0040] The working principle of this embodiment is as follows:

[0041] When installing the road pavement maintenance device, the roller 201 and the drive shaft 202 are installed at the bottom position of the stabilizing frame 1, and the driven shaft 203 is passed through the rotating hole of the stabilizing frame 1. Then, the driven shaft 203, the drive plate 204, the rocker arm 205 and the drive frame 206 are assembled, and the nozzle, the first drainage shell 301 and the second drainage shell 401 are respectively combined. Then, the first drainage shell 301 is installed at the outer position of the positioning rod 101 in conjunction with the first stabilizing column 3 to position it, and the second drainage shell 401 is installed at the upper position of the stabilizing frame 1 in conjunction with the second stabilizing column 4.

One side of the first drainage shell 301 and the second drainage shell 401 is connected with the drainage pipe and the storage tank of the water sprayer and herbicide sprayer in the prior art;

[0042] When the road surface maintenance device is used, the roller 201 is brought into contact with the road surface to control the movement of the water truck and the herbicide spraying truck. At this time, the roller 201 is forced to rotate, and the internal pressure of the storage tank is increased, so that the nozzle sprays water and sprays herbicides as needed. According to the principle of the crank slider, the roller 201 can control the drive frame 206 to swing back and forth laterally when it rotates. At this time, the drive frame 206 can control the first stabilizing column 3 and the first drainage shell 301 to connect the nozzle to swing laterally when it swings, thereby expanding the nozzle's lateral spraying range on the road. When the drive frame 206 moves back and forth, it can drive the second drainage shell 401 nozzle to swing up and down in a cycle, thereby expanding the nozzle's front and rear spraying range on the road.
