To provide a particulate matter spreader which can properly spread particulate matters having a variety of grain diameters into air.SOLUTION: A particulate matter spreader comprises: a hopper for making particulate matters which flow in through an upper end opening flow out through a lower end opening; an impeller supported to a rotating shaft which extends in a vertical direction at a lower part of the hopper; an impeller motor arranged below the impeller, and rotating the rotating shaft; and a spread cover arranged between the hopper and the impeller, and introducing the particulate matters moving outward in a radial direction by the rotation of the impeller to both sides of the particulate matter spreader in a width direction orthogonal to the vertical direction. In the spread cover (30), a supply port (38) for supplying the particulate matters which flow out of the lower end opening to an upper face of the impeller (20) is formed in a region including the rotating shaft (21) when planarly viewing the particulate matter spreader from the vertical direction.SELECTED DRAWING: Figure 10

    【課題】様々な粒径の粒状物を適切に空中散布することができる粒状物散布装置を提供する。【解決手段】粒状物散布装置は、上端開口を通じて流入した粒状物を下端開口を通じて流出させるホッパと、ホッパの下方において、上下方向に延びる回転軸に支持されたインペラと、インペラの下方に配置されて、回転軸を回転させるインペラモータと、ホッパ及びインペラの間に配置されて、インペラの回転によって径方向外向きに移動する粒状物を、上下方向に直交する粒状物散布装置の幅方向の両側に導く散布カバーとを備え、散布カバー(30)には、粒状物散布装置を上下方向から平面視したときに回転軸(21)を含む領域に、下端開口から流出した粒状物をインペラ(20)の上面に供給する供給口(38)が形成されている。【選択図】図10
