PROBLEM TO BE SOLVED: To improve a water-dividing device and a layout of a liquid feed hose in a boom sprayer. SOLUTION: The boom sprayer 10 is equipped with booms 22 and 24 movably attached to an apparatus frame 14, a plurality of nozzle pipes 26 and 32, in which at least one is arranged along the booms, having nozzles 28 and 30 for spraying a chemical and a pump apparatus 18 for sucking the chemical from a chemical tank 16 and feeding the chemical into nozzle pipes under pressure. In the boom sprayer 10, the boom sprayer 36 is arranged in the vicinities of chemical inlets of the nozzle pipes and a liquid feed hose 44 for feeding the chemical from a branched pipe of the water-dividing device is connected to each of the nozzle pipes. In the above constitution, only one liquid feed hose 34 is needed from the pump apparatus to the water-dividing device and length of the liquid feed hose 44 connected to the each nozzle pipe is shortened. Thereby, pressure lowering of the chemical can be reduced and stable spraying of the chemical is made possible and the constitution is also distributed to cost cut. COPYRIGHT: (C)2007,JPO&INPIT
