PROBLEM TO BE SOLVED: To solve a problem that a seedling transplanter is strongly required to be small and lightweight in order to facilitate work operability, but causes the weak stiffness of the arrangement structure of a transmission mechanism, short durability and unstable planting operation, when the structure of the frame is simplified.SOLUTION: This transmission device of the seedling transplanter is characterized by connecting, to a rear portion of a transmission case 2 interiorly mounting a travel transmission mechanism transmitting vehicle wheels 1, a seedling planting transmission case 5 in which a seedling planting input shaft A transmitted from the transmission mechanism of a transmission case 2, a seedling-supplying transmission shaft B for being branchedly transmitted from the seedling planting input shaft A to transmit to a seedling-supplying device 3 at a rear upper portion, and a planting transmission shaft C for lifting and transmitting a seedling-planting bill 4 at a rear lower portion are disposed at approximately triangle point shape positions on the side view to laterally mount the shafts in parallel. Vehicle wheels 1 are driven through the travel transmission mechanism of the transmission case 2 to travel the transplanting machine frame.COPYRIGHT: (C)2009,JPO&INPIT【課題】 苗移植機は、作業操作性を容易にするため、小形、軽量化することが強く要求されるが、フレーム構成を簡単にすると、伝動機構の配置構成の剛性が弱くなって、耐久性が短かく、植付作動も不安定となり易い。【解決手段】 車輪1を伝動する走行伝動機構を内装のミッションケース2の後部に、このミッションケース2の伝動機構から伝動される苗植入力軸Aと、この苗植入力軸Aから分岐伝動されて後上部の苗供給装置3を伝動する苗供給伝動軸Bと、後下部の苗植嘴4を昇降伝動する植付伝動軸Cを、側面視で略三角点形態位置に配置して横向平行に軸装の苗植伝動ケース5を連結した苗植伝動装置の構成とする。ミッションケース2の走行伝動機構を介して車輪1を駆動して移植機体を走行する。【選択図】 図1
