PROBLEM TO BE SOLVED: To provide a seedling transplanter having a simple machine structure, providing excellent ease of maintenance and preventing an untransplanted section of the seedling from being formed.SOLUTION: There is provided a seedling transplanter equipped with a seedling-transplanting part 4 for transplanting the seedlings on a plurality of rows, having a seedling-carrying platform 80 installed in the rear part of front wheels 6 and rear wheels 7, and having a seedling-carrying part 80b and partitioning wall parts 80a for partitioning the seedling-carrying part 80b by right and left each row, seedling-sending devices 97 for sending the seedlings on the seedling-carrying part 80b, seedling-transplanting devices 37 for transplanting the seedlings on a field, and seedling decrease-detecting devices 140 for detecting the decrease of the seedlings on the seedling-carrying part 80b, a buzzer 138, and a controller 157 operating the buzzer 138 when the decrease of the seedlings is detected by the seedling decrease-detecting devices 140. The seedling decrease-detecting devices 140 is constituted so as to detect the decrease of the seedlings in a plurality of the rows by one seedling decrease sensor 136. The formation of the untransplanted section can be prevented by the seedling decrease sensor 136, and the structure of the machine body becomes simpler to increase ease of maintenance compared to the case in which sensors are installed for every row.COPYRIGHT: (C)2014,JPO&INPIT【課題】機体構成が簡素でメンテナンス性に優れると共に、苗の未植付区間の発生を防止する苗移植機の提供である。【解決手段】前輪6及び後輪7の後部に設けられ、苗載部80bと苗載部80bを左右の各条毎に仕切る仕切り壁部80aとを備えた苗載台80と苗載部80b上の苗を移送する苗送り装置97と苗を圃場に植え付ける苗植付装置37と苗載部80b上の苗の減少を検出する苗減少検出装置140とを設けた複数条植えの苗植付部4と、ブザー138と、苗減少検出装置140により苗の減少が検出されるとブザー138を作動させる制御装置157とを備えた苗移植機であって、苗減少検出装置140は一つの苗減少センサ136で複数条の苗の減少を検出する構成である。苗減少センサ136によって苗の未植付区間の発生を防止できると共に、1条毎にセンサを設けた場合に比べて、機体の構成が簡素となりメンテナンス性も向上する。【選択図】図6
