To provide a granular material spraying buoyancy body capable of spraying seeds while propelling them on a water surface with propulsive power of a propulsive rotary body by arranging the propulsive rotary body on the buoyancy body.SOLUTION: The present invention is provided with a buoyancy body 1 movable in a state of floating on a water surface, and is provided with reciprocally rotatable longitudinal directional propulsive rotary bodies 2a-2d having a first rotary shaft 3a parallel to the longitudinal direction on an upper surface of the buoyancy body, and is provided with reciprocally rotatable lateral directional propulsive rotary bodies 4a, 4b having a second rotary shaft 3b in the orthogonal direction to the longitudinal direction on the upper surface of the buoyancy body. A granular material sprayer 7 is also arranged on the upper surface of the buoyancy body, and performs spraying operation of a granular material into the water by driving a sprayer in moving the buoyancy body in the advance direction by rotationally driving the longitudinal directional propulsive rotary body in the forward direction, and is constituted by the granular material spraying buoyancy body for stopping driving of the sprayer in moving the buoyancy body in the left direction or the right direction by driving the lateral directional propulsive rotary bodies in the forward direction or the inverse direction.SELECTED DRAWING: Figure 1
【課題】 浮力体上に推進用回転体を設け、推進用回転体の推進力で水面上を推進させながら種子を散布し得る粒状物散布用浮力体を提供する。【解決手段】 水面に浮いた状態で移動可能な浮力体1を設け、浮力体の上面に前後方向に平行な第1回転軸3aを有する正逆回転可能な前後方向推進用回転体2a〜2dを設け、浮力体の上面に前後方向に直交する方向の第2回転軸3bを有する正逆回転可能な左右方向推進用回転体4a,4bを設け、さらに浮力体の上面に粒状物の散布機7を設け、前後方向推進用回転体を正方向に回転駆動して上記浮力体を前進方向に移動中において散布機を駆動して粒状物の水中への散布動作を行うものであり、左右方向推進用回転体を正方向又は逆方向に駆動して浮力体を左方向又は右方向に移動中においては、散布機の駆動を停止する粒状物散布用浮力体により構成される。【選択図】 図1
