Description

Technical Field

[0001] The present invention relates to a dual - water - tank multi - functional spraying system, belonging to the field of construction machinery. Background Art

[0002] When a road roller compacts an asphalt road surface, it usually sprays water or emulsion on the wheel surface to prevent hot asphalt from adhering to the wheel surface. Thus, when the road roller passes over the road surface, the road surface material will not be lifted by the steel wheel, and the flatness and density of the road surface will not be damaged. In the prior art, the water - spraying tank and the emulsion - spraying tank equipped on the road roller both perform a single storage function. When spraying is carried out in one way, the other tank is left idle, resulting in waste. Summary of the Invention

[0003] Aiming at the problems existing in the above - mentioned prior art, the present invention provides a dual - water - tank multi - functional spraying system. When performing a single water - spraying function, the two tanks simultaneously serve as water tanks, which can increase the water - tank volume, avoid the time for stopping the machine to add water, and improve work efficiency. When both water - spraying and emulsion - spraying functions are required on the road roller, the two tanks respectively serve as a water tank and an emulsion - spraying tank. The whole system can achieve rapid switching to meet the use requirements.

[0015] The emulsified liquid switch, the emulsified liquid relay, and the emulsified liquid pump are connected in series to form an emulsified liquid control assembly;

[0016] The sprinkler control assembly and the emulsified liquid control assembly are connected in parallel and together with the main power switch and the power supply form a control circuit.

[0017] Further, each set of sprinkler pipe assembly includes a water delivery pipe and a plurality of nozzles arranged on the water delivery pipe. The sprinkler pipe assembly is used to spray pressurized water or emulsified liquid onto the surface of the roller of the road roller.

[0018] Further, one end of the water delivery pipe is provided with a water inlet joint.

[0019] Further, an exhaust port is further provided at the lower part of the main water tank, and a vent port is further provided at the upper part of the auxiliary water tank; when the water outlet of the main water tank is communicated with the water inlet of the auxiliary water tank, the exhaust port is communicated with the vent port.

[0020] Further, a water discharge port is provided at the bottom of the main water tank.

[0021] The main power switch is used to control the on and off of the power supply.;
