PROBLEM TO BE SOLVED: To provide a seedling transplanter capable of recognizing condition of seedlings to be supplied in a rear end part of a seedling tank without requiring a stoppage of planting travel when warning of reduction in an amount of seedlings is issued.SOLUTION: The seedling transplanter is composed of a riding-type traveling vehicle (2) for travelling in a field and a seedling transplantation part (4). The seedling transplantation part (4) is configured by providing: a plurality of seedling tanks (51) a planting device (52) detection members (71) for detecting the reduction in the amount of seedlings that detects seedling supply of each seedling tank (51), respectively and a notifying member thereof, and includes: a condition sensing member (73) for sensing the supply condition of loading seedlings in the rear end side of the seedling tanks (51) and reflecting to the notifying member a movable support mechanism (74) for movably supporting the condition sensing member (73) at the position where the condition sensing member can sense the each seedling tanks (51) and a moving control part for moving the condition sensing member (73) at the position of the seedling tank corresponding to the detected signal of the detection members (71) for detecting the reduction in the amount of seedlings by moving control of the movable support mechanism (74), for a predetermined holding time.COPYRIGHT: (C)2012,JPO&INPIT【課題】苗量減少警報が発報された際に、植付け走行の停止を要することなく、苗タンクの後端部の供給苗の状況把握を可能とする苗移植機を提供する。【解決手段】苗移植機は、圃場走行用の乗用走行車体(2)と移植部(4)とからなり、この移植部(4)は、複数条の苗タンク(51)と、植付装置(52)と、各苗タンク(51)の苗補充をそれぞれ検知する苗量減少検知部材(71)と、その報知部材とを設けて構成され、上記苗タンク(51)の後端側の積載苗の供給状態を感知して報知部材に反映する状態感知部材(73)と、この状態感知部材(73)を各苗タンク(51)について感知しうる位置に移動可能に支持する可動支持機構(74)と、この可動支持機構(74)の移動制御により苗量減少検知部材(71)の検知信号と対応する苗タンク位置に状態感知部材(73)を所定の保持時間について移動する移動制御部とを備えたものである。【選択図】図3
