PROBLEM TO BE SOLVED: To provide a fertilizer application device enabled to prevent a bridge in the vicinity of an agitator reliably in a hopper having a relatively large housing volume.SOLUTION: A fertilizer application device 1 includes a hopper 2 for housing a fertilizer and an agitator 3 disposed at a lower portion in the hopper 2 and having an agitation member 32 attached to a revolving shaft 31, so that the fertilizer is agitated by the rotation of the agitator 3 and discharged from a lower drop port 23a. In parallel with the revolving shaft 31 of the agitator 3, there is disposed a second revolving shaft 41, which is intermittently equipped with a pressure part 42. A rotary mechanism 43 is used, moreover, to rotate the second rotation shaft 41 forward and backward within the range of a constant angle so that the pressure part 42 is moved up and down to prevent the bridge.COPYRIGHT: (C)2015,JPO&INPIT【課題】比較的大きな収容容積を有するホッパー内においてアジテーター近傍におけるブリッジを確実に防止できるようにした肥料散布装置を提供する。【解決手段】肥料を収容するホッパー2と、当該ホッパー2内の下方に設けられ、回転軸31に攪拌部材32を取り付けたアジテーター3とを有し、アジテーター3の回転によって肥料を攪拌させて下方の落下口23aから排出するようにした肥料散布装置1において、アジテーター3の回転軸31と平行に第二回転軸41を設け、その第二回転軸41に間欠的に押圧部材42を設ける。そして、回転機構43を用いて第二回転軸41を正逆方向に一定角度の範囲内で回転させ、これによって押圧部材42を上下動させてブリッジを防止する。【選択図】図4
