PROBLEM TO BE SOLVED: To provide an inexpensive spraying apparatus having a simple structure and easily, rapidly and vertically moving a tank by easy manual operation.SOLUTION: The spraying apparatus is mounted on a rotary 2 of a self-propelled working vehicle and formed of a tank 4 for housing a material to be sprayed in the interior thereof, a spraying mechanism 5 installed in the lower part of the tank 4 and a spraying hose 6 mounted in the lower part of the spraying mechanism 5. The tank 4 is freely shakingly mounted in the rotary 2 so as to be vertically movable while maintaining a horizontal posture with a parallel link mechanism 20. Furthermore, the parallel link mechanism 20 is equipped with an elastic member 21 for applying the elasticity in the standing direction to the parallel link mechanism 20 during standing and rotation thereof.COPYRIGHT: (C)2008,JPO&INPIT【課題】構造が簡単でコスト的に安くなり、ワンタッチの手作業で軽く速やかにタンクを上下動させることができる散布装置を提供する。【解決手段】自走式作業車のロータリー2に取付けられ、その内部に散布物を収納するタンク4と、このタンク4の下部に設けられた散布機構5と、前記散布機構5の下部に取付けられた散布ホース6で形成された散布装置であって、前記タンク4をロータリー2に平行リンク機構20を用いて水平姿勢を保ったまま上下に移動できるよう揺動自在に取付け、この平行リンク機構20に、平行リンク機構20の起立回動時に起立方向の弾性を付勢する弾性部材21が設けてある。【選択図】図1
