PROBLEM TO BE SOLVED: To provide a granule feeder (seedling transplanter) enabling that an operator can easily recognize run out of granules and surely replenish the granules to a granule-storing portion.SOLUTION: The granule feeder equipped with a rotary feeder 61 for receiving the granules from a fertilizer hopper 60 and discharging the granules at a prescribed feeding rate is provided with a residual quantity sensor 57 for detecting whether the quantity of the granules stored in the granule-storing portion 60 is a preset prescribed quantity or more, a buzzer 58 which is operated, when the residual quantity sensor 57 detects a quantity less than a prescribed quantity, a notification-stopping switch 59 for stopping the operation of the buzzer 58, a feeding rotation sensor 45 for detecting the rotational speed of the feeding roll 73 of the feeder 61, and a control constitution for again operating the buzzer 58, when the feeding rotation sensor 45 detects a prescribed rotational speed or more after the operation of the notification-stopping switch 59. The operator is prevented from forgetting a work for granule-replenishment, when the operator approaches the end of a field.COPYRIGHT: (C)2013,JPO&INPIT【課題】作業者が、粉粒体が無くなったことを容易に認識でき、粉粒体の貯留部への補充を確実に行うことができる粒状体供給装置(苗移植機)を提供すること。【解決手段】肥料ホッパ60から披露を受けて所定量ずつ放出する回転式の繰出部61を備えた粒状体供給装置において、粒状体貯留部60に貯留された粒状体が予め設定された所定量以上か否かを検知する残量センサ57と、該残量センサ57が所定量未満を検知すると作動するブザー58と、該ブザー58の作動を停止させる報知停止スイッチ59と該繰出し装置61の繰出ロール73の回転数を検出する繰出し回転センサ45と、該報知停止スイッチ59を操作した後に繰出回転数センサ45が所定数以上の回転数を検知すると再度、ブザー58を作動させる。作業者が圃場端に接近した際に粒状体の補充作業を忘れることが防止される。【選択図】図9
