Road roller, water spray control system and method

Abstract

The invention provides a road roller, a water spray control system and a method, wherein the water spray control system comprises a water tank, two water supply branches and two water spray pipe groups; each water supply branch comprises a water filter which is connected with the water tank, a water pump which is connected with the water filter and the two water spray pipe groups, and a flushing control switch; the first end of the flushing control switch is connected with a water outlet of the water pump, and the second end of the flushing control switch is connected with a water inlet of the water pump in the other water supply branch; the water spray control system also comprises a water spray control switch and a controller; one end of the water spray control switch is connected with the water outlets of the water pumps in the two water supply branches, and the other end of the water spray control switch is connected with the two water spray pipe groups; the controller is used for controlling the off of the water spray control switch when the water amount of the water pumps in the two water supply branches is lower than a preset value, and controlling the flushing control switches in the two water supply branches to be sequentially communicated for a preset time. In the invention, the water filters are automatically cleaned, the water spray quality is improved and the service life of the water pumps is prolonged.

Description

technical field [0001] The invention relates to the field of road rollers, in particular to a road roller and a sprinkler control system and method. Background technique [0002] When the double-steel-wheel vibratory roller or tire roller is performing construction operations, in order to prevent the steel wheels or tires from sticking to asphalt material and affecting the quality of road construction, a sprinkler system is generally equipped. Each sprinkler system mainly adopts the intermittent sprinkler method, such as figure 1 As shown, it comprises: a set of water tank 101, a water filter 102, water pump 15, water pump 17, front sprinkling pipe group 18, rear sprinkling pipe group 19 and check valve 103, water pump 15 and water pump 17 alternate gap sprinkling, can greatly Improve the service life of the water pump. [0003] However, due to the poor water quality added to the water tank at the construction site, impurities often block the water filter or the water pipe...

AI Technical Summary

Problems solved by technology

[0003] However, due to the poor quality of water added to the water tank at the construction site, impurities often block the water filter or the water pipeline, and the water pump 15 or the water pump 17 sucks less water, resulting in lower water output from the front sprinkler pipe group 18 and the rear sprinkler pipe group 19. Insufficient or poor atomization effect, uneven watering, resulting in sticky steel wheels or tires

In addition, if the water inlet back pressure of the water pump 15 and the water pump 17 is maintained at a high level for a long time, its service life will be greatly reduced
