PROBLEM TO BE SOLVED: To provide a paddy field working vehicle brought to be able to automatically discharge fertilizer remaining in the hopper of a fertilizing device to the outside.SOLUTION: The paddy field working vehicle includes a delivery device 61 for receiving the fertilizer from a fertilizer hopper 60 for storing the fertilizer and discharging a predetermined amount of the same to a farm field or the like and a blower 67 for blowing and conveying the fertilizer. In the vehicle, a freely rotative shutter 84 and a motor 111 for rotating the shutter 84 are installed to a fertilizer discharge port 83 for discharging the fertilizer from the fertilizer hopper 60 with facing a recovery part, and the vehicle is equipped with a control mechanism for bringing the wind power of the blower 67 to be stronger by increasing the shutter opening of the shutter 84 to be larger than a case when a controller 100 conveys the fertilizer to the delivery device 61 and also increasing the number of rotation of an engine, when an operation switch 112 for switching the fertilizer to move to either one of the delivery device 61 and the fertilizer discharge port 83 from the hopper 60 is operated to the side of fertilizer discharge.COPYRIGHT: (C)2012,JPO&INPIT【課題】施肥装置のホッパに残った肥料を自動的に外部に排出することができるようにした水田作業車両を提供すること。【解決手段】肥料を貯留する肥料ホッパ60から肥料を受けて所定量ずつ圃場などに放出する繰出装置61と肥料を送風搬送するブロワ67を設けた水田作業車両において、肥料ホッパ60からの肥料を回収部に向いて排出するための肥料排出口83に回動自在のシャッタ84とシャッタ84を回動させるモータ111を設け、ホッパ60から繰出装置61と肥料排出口83のどちらに肥料が移動するかを切り替える切替操作スイッチ112を肥料排出側に操作すると、制御装置100は繰出装置61へ肥料を搬送する場合よりシャッタ84の開度を大きくし、かつエンジン回転数を上げてブロア67の風力を強くする制御構成を備えている。【選択図】図7
