To increase capacity of a tank by disposing a driving part such as a motor outside the tank while adopting a structure that allows weight balance to be easily acquired, and make the machine body including the tank compact in a grain material spraying device for executing aerial spraying.SOLUTION: An aerial spraying device includes a tank in which a sprayed material is stored, a body frame having a supply port to which a lower end opening of the tank is connected for storing a motor with a rotation drive shaft coaxial with the center of the supply port, and a spray cover attached to the lower end of the body frame for incorporating an impeller attached to the rotation drive shaft. The body frame includes a storage chamber in which a drive part including the motor is stored, and a sprayed material supply passage for dropping the sprayed material onto the impeller through the outside of the storage chamber from the supply port.SELECTED DRAWING: Figure 5

    【課題】空中散布を行う粒材散布装置において、重量バランスを得やすい構造でありながら、タンクの外にモータなどの駆動部を配備してタンクの収容量を高め、タンクを含めた機体をコンパクトにする。【解決手段】空中散布装置は、散布物が収容されるタンクと、タンクの下端開口部が接続される供給口を有し、供給口の中心と同軸の回転駆動軸を備えるモータを収容する本体枠と、本体枠の下端に取り付けられ、回転駆動軸に取り付けられたインペラを内部に収容する散布カバーとを備え、本体枠は、モータを含む駆動部が収容される収容室を備えると共に、供給口から収容室の外側を通ってインペラ上に散布物を投下させる散布物供給路を備える。【選択図】図5
