Road roller with good pavement leveling effect

Abstract

The invention belongs to the technical field of road engineering mechanical equipment, and particularly relates to a road roller with a good pavement leveling effect. Aiming at solving the problem that in the process of rolling an asphalt pavement by a road roller, attachments are likely to be carried, and consequently pavement smoothness is affected, the following scheme is proposed currently, the road roller comprises a bracket, two connecting bodies are welded to one side of the bracket, cams are rotationally connected to the sides, close to each other, of the two connecting bodies correspondingly, a working wheel is welded between the two cams, and two circular through holes are formed in one side of the top end of the bracket. An inflating pump inflates the interior of a water tank byutilizing kinetic energy of the road roller during travelling, a water flow is evenly sprayed to the surface of the working wheel, asphalt adsorption is avoided, the center of gravity of the road roller shifts due to a counterweight block, thus the rolling force of the working wheel is conveniently controlled when the temperature of asphalt is different, the rolling effect is improved, meanwhile,the shock absorption effect of a cockpit is good, a scraper can scrape off the asphalt on the surface of the working wheel, at the same time the situation is fed back to a solenoid valve, the water amount of a water delivering pipe is increased, and the situation that the working wheel adsorbs the asphalt again is avoided.

Description

technical field [0001] The invention relates to the technical field of road construction machinery and equipment, in particular to a road roller with good road surface smoothing effect. Background technique [0002] Road roller is a kind of mechanical equipment used in road engineering construction. It mainly compacts road construction materials by its own gravity. Generally, when compacting asphalt pavement, water is sprayed on the surface of the working wheel to avoid the surface of the working wheel being rotated. The asphalt is brought up, affecting the smoothness of the road surface. [0003] After retrieval, the Chinese patent application number CN201620651087.3 discloses a road roller with a water spray device, which includes a front frame, a rear frame hinged to the front frame, a front vibrating wheel and a rear vibrating wheel; a road roller; It also includes a water spray device and a water replenishing device. The water spray device includes a first water spray ...

AI Technical Summary

Problems solved by technology

A road roller in the above-mentioned patent has the following disadvantages: in the process of rolling, the water spray rate cannot be adjusted, and when the speed of the road roller is too fast, the asphalt may be carried by the working wheels; when the speed of the road roller is slow, the water flow will make the asphalt Rapid cooling will affect the rolling effect, so we propose a road roller with good road surface leveling effect
