REPULSIVE WALL FOR SCATTERING SOIL AND SOIL-SCATTERING DEVICE USING THE SAME AND USED FOR SEEDLING BOX, AND METHOD FOR SCATTERING SOIL IN SEEDLING BOX BY USE OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a repulsive wall which has a new structure enabling to homogeneously spread soil having a fine particle diameter over a surface layer for sowing seeds and is used for scattering the soil, to provide a soil-scattering device which has a new structure using the repulsive wall and is used for seedling boxes, and to provide a new method for scattering soil in seedling boxes, which uses the same.;SOLUTION: This repulsive wall for scattering soil, characterized by comprising a repulsive wall main body 2 which is inserted and disposed at an inclination angle of at least about 30° to a vertical plane within a bed soil-dropping range in a seedling box bed soil supply mechanism 4 enabling to continuously drop and supply the bed soil 7 in an approximately constant amount per a prescribed time, and is formed in a planar shape capable of covering the dropping range, and a connection fitting 3 forming a main body fixed portion on whose one end side has a connection portion 34 capable of being connected to a proper site in the seedling box bed soil supply mechanism 4 and on whose other end side the repulsive wall main body 2 can be disposed and fixed at a desired angle θ in a region of about 30° to about 60° to a vertical plane within a range for dropping the bed soil 7.;COPYRIGHT: (C)2002,JPO
