摘要： PROBLEM TO BE SOLVED: To provide a solution sprinkler, by which a solution can be sprinkled efficiently and economically, even a controller at a remote place can be informed quickly of the case of the small quantity of the solution stored and abnormal sprinkling and a snow-melting effect and an antifreezing effect are obtained sufficiently. SOLUTION: The solution sprinkler has an underground tank, in which a solution Y is stored, an iron pipe 2 carrying the solution to a road surface R, a nozzle unit 3 spraying the solution onto the road surface, a spray pump 4, a peripheral environment detecting means 5 detecting peripheral environment, and a control board unit 6 controlling the operation of the spray pump. The solution sprinkler has a motor-operated valve 7 adjusting the quantity of the solution carried, a flow meter 8 detecting the quantity of the solution carried, and a carrying-quantity program setting means, a detection result by the flow meter and peripheral-environment information detected by the peripheral-environment detecting means and the time elapsed after the start of the operation of the spray pump are collated during the operation of the spray pump, and the a scattering-quantity control mechanism controlling the carrying-quantity adjusting means so that the quantity of carrying follows a scattering method or the quantity of scattering set by the carrying-quantity program setting means is installed.
