【０００２】
【発明が解決しようとする課題】
従来、肥料ホッパの残留肥料取出口の下方に肥料回収容器を配置させて、取出口のシャッタの開動作により自然落下する肥料を回収容器に回収しているが、排出作業時には排出される肥料が周辺に飛散したり、肥料ホッパ内の残留肥料を一回で回収容器に回収させるためには回収容器の容量も大きくなって、この場合回収容器の設置スペースも大きなものを必要とさせるなどの問題があった。
【０００３】
【課題を解決するための手段】
したがって本発明は、機体に装備させる肥料ホッパ内の残留肥料を排出する残留肥料取出口と、排出された肥料を留める案内体とを設けると共に、伸縮可能な肥料案内部材によって前記残留肥料取出口に前記案内体を接続させる構造であって、前記肥料案内部材は、蛇腹状のホース体と網目状のホース体を有し、前記蛇腹状のホース体を外側とし、前記網目状のホース体を内側とした二重構造に形成したもので、取出口から案内体への肥料排出中における周辺への肥料飛散を解消させて良好な肥料回収を可能にすると共に、たとえホッパ内の回収容量より案内体容量が小の場合でも、案内体満杯時に取出口の開閉シャッタをその都度閉とさせて案内体内の肥料を排出させる手間の煩わしさなく、シャッタの開動作を維持させたまま案内体内の肥料を肥料袋などに回収させる連続した肥料回収作業を可能にして、残留肥料の回収作業での能率向上を図るものである。
【０００４】
また、前記蛇腹状のホース体の蛇腹の隙間に肥料が付着し固定化するなどの不都合を前記網目状のホース体で防止し、ゴム材などで形成する蛇腹状ホース体の伸縮率と耐久性を向上させて、前記案内体を左右方向に自在に傾斜させ、この傾斜下端側から肥料を排出させる肥料排出作業の信頼性と能率の向上を図るものである。
