PROBLEM TO BE SOLVED: To compose a granular powder spraying apparatus capable of downsizing by reasonable arrangement of an actuator which supplies the granular powder, a control board and the like.SOLUTION: The granular powder spraying apparatus includes: an electromagnetic solenoid 26 which supplies a granular agent from a hopper 21 an electric motor 27 which rotary drives an rotary vane 28 around a vertical shaft core Y to diffuse the supplied agent and the control board 31 which controls them. The electromagnetic solenoid 26 and the control board 31 are adjacently arranged in a position near the electric motor 27 above a diffusion space S where the granular powder is diffused horizontally by the rotary vane 28.COPYRIGHT: (C)2012,JPO&INPIT【課題】粉粒体を繰り出すアクチュエータと制御基板等の合理的な配置により小型化が可能な粉粒体散布装置を構成する。【解決手段】ホッパー21から粉粒状の薬剤を繰り出す電磁ソレノイド26と、繰り出された薬剤を拡散させるため回転羽根28を、縦軸芯Yを中心に駆動回転する電動モータ27と、これらを制御する制御基板31とを備えている。回転羽根28で水平方向に粉粒体を拡散させる拡散空間Sの上方で、電動モータ27の近傍位置に電磁ソレノイド26と制御基板31とを隣接配置した。【選択図】図3
