Road roller and water spraying system thereof

Abstract

The invention discloses a road roller and a water spraying system thereof. The water spraying system comprises a water tank, a water pump and a spraying device, and further comprises a preheating device, wherein the preheating device is arranged on a pipeline between the water pump and the spraying device, and is used for preheating the cold water sprayed by the spraying device; a water temperature control system is connected with the preheating device and is used for detecting the water temperature and controlling the flowing speed. The water spraying system provided with the preheating function can prevent cold water from being directly sprayed onto a vibration wheel of the road roller, so as to prevent the influence of vibration wheel on the pavement construction temperature, prevent the construction material from being stuck onto the vibration wheel to influence the construction quality and enhance the cleaning difficulty.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a road roller sprinkler system and a road roller equipped with the water sprinkler system. Background technique [0002] During the construction of asphalt pavement, the vibratory roller (such as a double-steel roller) exerts a vibratory compaction excitation force on the asphalt mixture in large-area contact with the asphalt material, and applies an appropriate pressure to the asphalt mixture after paving. Solidity, so that the asphalt pavement has a certain bearing capacity and stability. [0003] When the vibrating wheel is in contact with the asphalt mixture, the asphalt mixture is bonded to the vibrating wheel. The rough surface of the vibrating wheel will affect the quality of the road surface after rolling. At present, it is generally necessary to continuously use the sprinkler system of the road roller to sprinkle water on the vibrating wheel. To prevent the asphalt...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention provides a road roller sprinkling system, the sprinkling system is provided with a preheating device, the preheating device heats the cold water to be sprayed to a preset value, which solves the problem of the low temperature of the vibrating wheel on the asphalt pavement during construction. The impact of compaction temperature also solves the problem that the asphalt mixture sticks to the vibrating wheel during the construction process, which affects the construction quality of the road surface and increases the cleaning strength.
