In construction process of asphalt pavement, road roller plays a part flattening-out and compacting to each paving layer.But when rolling asphalt material paving layer, due to bituminous mixture high temperature sticky nature, being easy to stick in road roller steel wheel (tire), directly affecting compaction quality.
Corresponding the problems referred to above, generally adopt two kinds of methods, and one is by manually smearing pitch in road roller steel wheel (tire), and one is by steel wheel (tire) surface sprinkling.First method wastes time and energy, and adopts less.If second method water rate control is improper, be easy to the quality and the production efficiency that directly affect pavement compaction.Traditional road roller generally adopts equipped sprinkling system, and this sprinkling system, owing to adopting manually operated mode, causes injection flow rate can not accurate adjustment at any time, and in work progress, water content consumption is too fast, and frequently adding water affects construction speed.
Summary of the invention
The purpose of this utility model is to provide a kind of road roller to prevent adhesion spray control system, and it is inaccurate that it can solve the spray water injection flow rate that causes of Artificial Control, and affect construction quality of pavement, water content consumption is excessive, affects the problem of efficiency of construction.
For solving above-mentioned topic, the utility model is achieved through the following technical solutions:
Road roller described in the utility model prevents adhesion spray control system, comprise water pump, front shower nozzle, rear shower nozzle and control module, described front shower nozzle is connected with water pump by water supply line with rear shower nozzle, water pump is connected with water receiving case, and described control module comprises water pump and controls solid-state relay, sprinkling controller, spray modes selector switch, sprays interval GSS Gear Select Switch, Flow-rate adjustment potentiometer and vehicle speed sensor; Described water pump controls solid-state relay by communication line and water pump and is connected, water pump controls solid-state relay and is connected with sprinkling controller, spray controller respectively with spray modes selector switch, sprays interval GSS Gear Select Switch, Flow-rate adjustment potentiometer and vehicle speed sensor and is connected, the connection of described vehicle speed sensor controls solid-state relay by communication line and water pump, spray modes selector switch, Flow-rate adjustment potentiometer are connected.
Say further, the water pump described in the utility model comprises water pump first, water pump second, and described water pump first is connected with water supply line by converging valve block with water pump second.
Say further, the spray modes selector switch described in the utility model comprises manual mode and automatic mode.
Compared with prior art, the utility model has following beneficial effect:
1, the utility model adopts accurate control strategy, and ensure that water pump can carry out spraying operation according in real time, accurately, efficiently, preventing adhesiving effect is obvious.
2, the utility model can regulate different parameters, meet different operating mode, different operating person operation use demand, improve the adaptability for working condition of sprinkling system.
3, the utility model adopts Dual-pump flow-converging to arrange, namely adopt two water pumps with the shower nozzle water supply forwards, backwards simultaneously of the mode at interflow, even if a water pump breaks down in work progress, another one still can meet sprinkling demand, ensure that construction is normally carried out, meet the reliability of system.
4, the utility model can reduce the filling operation of water tank, reduces because frequently add water the problem affecting efficiency of construction caused.
The reception of switching signal that 5, the utility model is compatible, analog signal and process, system intelligent controlling extent is high; Each interface is easy to connect simultaneously, is easy to same machine system coupling and uses.
