<P>PROBLEM TO BE SOLVED: To provide a seedling transplanter, photographing the magnitude of farm's unevenness and seedlings' planted posture by a photographic device and automatically stabilizing the vertical movement of its seedling planting apparatus and seedlings' planted posture in accordance with images thus photographed. <P>SOLUTION: The seedling transplanter is such that: a seedling planting apparatus 8 is installed on the rear side of its traveling vehicle 14 with front wheels 10 and rear wheels 12; wherein the seedling planting apparatus 8 includes: a seedling tank 6 feeding seedlings to a seedling-receiving guide 5 provided with a seedling-receiving port 4; a center float 1 and a side float 2 laid under the seedling tank 6 and sliding on farm's surface; and a planting mechanism 7 planting seedlings through making the seedling-receiving port 4 descend. In this seedling transplanter, a photographic device 17 photographing an image representing farm surface's unevenness is provided and laid above the seedling planting apparatus 8, the magnitude of farm surface's unevenness is determined based on the image photographed by the photographic device 17, and a control is constituted such that: when there are plenty of such unevenness, the lift control sensitivity of a lift cylinder 15 making a lift link 16 ascend/descend is lowered, while when there are slight such unevenness, sensitivity of the lift cylinder 15 is raised. <P>COPYRIGHT: (C)2013,JPO&INPIT |
