【発明の属する技術分野】
本発明は例えば苗載台及び植付爪を備えて連続的に苗植作業を行う田植機の施肥装置に関する。
【0002】
【発明が解決しようとする課題】
従来、施肥ホッパ内の肥料を送風機からの搬送空気でもって肥料排出部まで搬送して施肥を行う施肥ホースを備えた手段にあっては、肥料詰まり時に空気を逃す空気逃しを、施肥ホースや肥料排出部に分岐形成していて、通常時は空気逃し出口に設ける蓋を閉保持して該出口より空気が排出されるのを防止している。しかし乍ら肥料詰まりなどによって空気逃しより空気が排出される場合、施肥時の肥料が空気と一緒に排出されて、植付部の各種装置をこの肥料でもって汚すなどして錆を発生させたり、作動不良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】
然るに、本発明は、施肥ホッパ内の肥料を送風機からの搬送空気でもって肥料排出部まで搬送して施肥を行う施肥ホースを備えた田植機の施肥装置において、前記肥料排出部の余剰空気を上方位置で排出する空気排出ホースを肥料排出部に連通接続させ、空気排出ホースの上端排出口を上方位置で下向きに臨ませたもので、排出ホースに水が侵入し肥料が付着して、肥料詰まりを発生させるなどの不都合を確実に防止するものである。
