An automatic chemical spraying device is provided to make a chemical bag and a chemical liquid supply hose move in a predetermined section while spraying various chemicals and water by using a wire. An automatic chemical spraying device includes plural driving pulleys(3,3a,3b,3c), driven pulleys(4,4a,4b,4c), endless wires(5,5a,5b,5c), plural support rollers(6), a driving unit, limit switches(8,9), carriers(12,12a,12b,12c), hose hangers(16,16a,16b,16c), a distributor, valves(18,18a,18b,18c,) and a controller(19). The endless wire is wound on the driving and driven pulleys. The limit switch senses the moving section of the wire. The carrier is fixed on the wire and is installed on each rail. The hose hanger supports hoses(15,15a,15b,15c) that connect a chemical bag and a sprayer.
