AI Technical Summary

Technical Problem

The existing sprinkler trucks cannot move forward at a uniform speed when they encounter obstacles from drainage pipe ditches or other obstacles, resulting in unstable sprinkling of water, which will affect the road maintenance effect and waste water resources.

Method used

A spray device for road maintenance is designed, including a special sprinkler truck, a large-capacity water tank, a spray rack, a half shaft, a drive wheel, a drive belt, a driven wheel, a water inlet pipe, a spray width adjustment mechanism and a flow limiting mechanism. Through the transmission coordination of the current limiting mechanism, the water flow inside the water inlet pipe is controlled, and the uniform spraying speed of the sprinkler truck is realized, and the height and width of the spraying are adjusted through the spray width adjustment mechanism.

Benefits of technology

The uniform spraying of the sprinkler truck is achieved, avoiding inconsistent amount of water sprinkler on the road surface, improving the road surface maintenance effect, saving water resources, and improving the flexibility and applicability of spraying.

Abstract

The utility model provides a spraying device for pavement maintenance, belongs to the technical field of spraying devices for pavement maintenance, and aims to solve the problems that when a watering cart runs at a non-uniform speed, the water spraying amount of a pavement is easily inconsistent; comprising a special watering cart, a large-capacity water tank, a spraying frame, a half shaft, a driving wheel, a transmission belt, a driven wheel, a spraying width adjusting mechanism and a flow limiting mechanism. The large-capacity water tank is arranged above the special watering cart; the spraying frame is arranged on the right side of the special watering cart; the half shaft rotates below the special watering cart; the driving wheel is coaxially and fixedly connected to the periphery of the half shaft; the driven wheel is rotationally connected to the lower portion of the special watering cart. The transmission belt is rotationally connected to the peripheries of the driving wheel and the driven wheel; the spraying width adjusting mechanism is arranged in the spraying frame; the flow limiting mechanism is arranged below the special watering cart. According to the utility model, the uniform-speed spraying of the special watering cart is realized, the situation of inconsistent water spraying amount of the pavement is avoided, and the pavement maintenance effect is improved.
