Seedling taking of the transplantation machine Out manner and device

摘要

PURPOSE: To obtain the subject device capable of rapidly and accurately taking out a seedling soil from a seedling tray, and subsequently surely releasing the seedling soil from seedling- taking tines to accurately feed the seedling soil into a planting device without damaging the seedling soil and the leaves of the seedling. ;CONSTITUTION: A pair of mutually separated seedling-taking tines 4 are forward moved, while reducing the distance between the tips of the tines with a tine guide 6, and the tines 4 are further thrust into a seedling soil 5 in a pot 3 set in a seedling tray so that the tines are separated from the center line of the seedling soil 5 on the surface side of the seedling soil and approached the center line on the side of the bottom surface. After the tines 4 are thrust into the seedling soil, the seedling-taking tines and the tine guide are together separated from the seedling tray to take out the seedling. The postures of the seedling-taking tines are changed into an approximately lower direction faced to a planting cylinder 43. The tine guide is moved toward the tine tips to enlarge the distance between the tips of the seedling-taking tines and simultaneously push out the seedling soil. While the posture of the pushed seedling soil is corrected, the pushed seedling soil is fed into a planting cylinder. After the movement of the tine guide toward the tine ends is finished, the tine guide is retreated together with the seedling-taking tines. The postures of both the seedling-taking tines and the tine guide are changed into an approximately horizontal posture directed to the pot. The tips of both the seedling-taking tines and the tine guide are moved toward the lower side of the leaves of a seedling soil.;COPYRIGHT: (C)1996,JPO
