PROBLEM TO BE SOLVED: To provide a chemical liquid dispersing device of an unmanned helicopter, having a simplified pipe and enabling easy cleaning of the pipe.SOLUTION: The chemical liquid dispersing device 5 of the unmanned helicopter 1 includes: chemical liquid tanks 52L and 52R arranged on the right and left of an airframe a pair of right and left pumps 53L and 53R spray devices (atomizer spray devices 55L, 55R, and a center nozzle 55C) and a pipe for connecting the components. The chemical liquid dispersing device 5 of the unmanned helicopter 1 disperses chemical liquid in air by driving the pair of right and left pumps 53L and 53R. One end of each of right and left supply pipes 57L and 57R is connected to each of the pair of right and left chemical liquid tanks 52L and 52R. The other end of each of the right and left supply pipes 57L and 57R is connected to one end of one interflow pipe 58. The other end of the interflow pipe 58 is connected to water suction side pipes 59 and 59 connected to the pair of right and left pumps 53L and 53R. The interflow pipe 58 includes a line filter 70.COPYRIGHT: (C)2012,JPO&INPIT【課題】装置内の配管を簡素化し、当該配管の清掃を容易に行うことのできる無人ヘリコプターの薬液散布装置を提供する。【解決手段】機体の左右に配設される薬液タンク52L・52Rと、左右一対のポンプ53L・53Rと、噴霧装置(アトマイザー噴霧装置55L・55R、センターノズル55C)と、これらを接続するする配管とを備えて、前記左右一対のポンプ53L・53Rの駆動によって薬液を空中に散布する無人ヘリコプター1の薬液散布装置5において、前記左右一対の薬液タンク52L・52Rに左右の供給配管57L・57Rの一端を接続し、該左右の供給配管57L・57Rの他端を一つの合流配管58の一端と接続し、該合流配管58の他端を左右一対のポンプ53L・53Rと接続する吸水側配管59・59と接続し、前記合流配管58にラインフィルター70を設けた。【選択図】図5
