FORCED SEEDLING-TRANSPORTATION APPARATUS FOR FIX-PLANTING MACHINE

摘要

PURPOSE:To easily achieve the complete automation of a seedling-transportation work using integrated mechanical operations by selectively extracting a seedling from a prescribed cell of a raising seedling tray by a seedling-extraction apparatus and forcedly transferring the seedling to a seedling transplantation apparatus by sucking with vacuum. CONSTITUTION:A suction part 403 is provided with a cylindrical surrounding member 405 enclosing a plurality of uniformly separated openings 404 opened on the circumferential wall at the downstream part of a transfer pipe 303. An end of a suction pipe 402 is hermetically connected to the circumference of the surrounding member 405. The seedling transferred from the upstream side of the suction part 403 can be transferred to the downstream part of the suction part 403 (the direction shown by the arrow C) while preventing the suction of the seedling into the suction pipe 402. The vacuum transportation of the seedling through the transfer pipe 303 can be surely performed by attaching a shut-off valve 406 at the terminal of the transfer pipe 306. The extraction of a seedling from the bottom face of a raising seedling tray can be carried out by connecting a forced transfer apparatus 4 and a seedling extraction apparatus with the transfer pipe 303.
