ABSTRACT:
This invention relates to a transplanter of seedlings useful for supplying seedlings in a controlled state. Seedlings grown in paper tubes which are a mixture of superior and inferior seedlings are placed on a seedling supplying conveyor and separated into individuals at a certain interval by a seedling separating apparatus at the terminal of the conveyor. Behind the seedlings separating apparatus is a string-like belt to support roots and leaves, to which is supplied seedlings obtained by separation. Inferior seedlings free of leaves fall onto the string-like belt to transfer only superior seedlings. Behind the string-like belt is a seedling controlling conveyor rotating at a certain velocity, to which seedlings are transferred. In the vicinity of the seedling accepting part of the seedling controlling conveyor there is provided a seedling detector and a circuit to control the accumulation of seedlings by rotating the seedling supplying conveyor slower when the seedlings on the seedling conveyor increases or by rotating the seedling supplying conveyor faster when the seedlings decrease, so as to transfer the seedling at a controlled state.
