PROBLEM TO BE SOLVED: To provide a fertilizer-dispersing device capable of well applying over a wide range the fine adjustment of the dispersing amount of a dispersing object charged in a hopper, without enlarging the fertilizer-dispersing device, even in the case of electric remote control.SOLUTION: In the fertilizer-dispersing device, an adjusting portion 104 is set between a hopper 102 and a dispersing portion 103, wherein a bottom plate 201, a shutter plate 202 and a switching plate 203 are freely slidably overlapped each other. The shutter plate 202 changes the opened area of a fall down hole from the full open to the close by rotation. The switching plate 203 changes the opening area of the fall down hole of the shutter plate 202 from the full open to the partial open by rotation. A detecting means 300 for detecting the switching state of the switching plate 203 is provided to exhibit the switching state on an operation portion 301.COPYRIGHT: (C)2012,JPO&INPIT【課題】肥料散布装置を大型化させることなくホッパに投入された被散布物の散布量の細かな調整をより広範囲にまた、電動遠隔操作の場合でも良好に使用できる肥料散布装置を提供する【解決手段】調整部104は、ホッパ102と散布部103との間に設けられ、底板201とシャッタ板202と切換板203とを互いに摺動自在に重合させて構成される。シャッタ板202は、回動することで落下孔の開口面積を全部開放と閉止との間で変化させる。切換板203は、回動することでシャッタ板202の落下孔の開口面積を全部開放と一部開放との間で変化させる。切換板203の切換状態を検知する検知手段300が設けてあり、操作部301に切換状態を表示する。【選択図】図3
