A seedling with soil selecting and transporting apparatus for a transplanting machine which can steadily and certainly discriminate good seedlings with soil and no good seedlings with soil without causing operation failure by deposition of a clump of earth even if external vibration and/or slight disturbance is caused in transporting attitude of the seedling with soil. The seedling with soil selecting and transporting apparatus for a transplanting machine transports good seedlings having leaf portions grown into a normal length and no good seedlings having leaf portions not grown into a normal length. The apparatus comprises a strip form transporting belt transporting good and no good seedlings with soil in an attitude wherein they are fallen sideways and have concentrically mounted soil depositing portions on one outer side edge portion of the strip form transporting belt. A clamping belt clamps leaf portions of good seedlings with soil among the good and no good seedlings mounted on the strip form transporting belt. The strip form transporting belt has its one outer side edge deflected downwardly for slipping down only no good seedlings having leaf portions not clamped by the clamping belt.

The invention provides a seedling transportation apparatus of a simple structure wherein a new seedling tray can be supplied readily without immediately removing an emptied old seedling tray and does not interfere, when it is moved toward the downstream side in a transportation direction, with a transportation operation for a seedling. To this end, transportation of a seedling tray is performed not in an upright condition or in a curved or bent condition but in a horizontal condition. The seedling transportation apparatus for a transplantation machine includes a seedling taking out apparatus for taking out a seedling upwardly from a seedling tray having seeding accommodating cells in which seedlings are accommodated, a tray transportation apparatus having a horizontal transport path for transporting the seedling tray toward the seedling taking out apparatus, a seedling carrying out conveyor disposed at a location higher than the horizontal transport path of the tray transportation apparatus, and a transferring apparatus for transferring the seedling taken out by the seedling taking out apparatus onto the seedling carrying out conveyor.

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.

A method and a device for picking up seedlings from a seedling tray is capable of picking up seedlings by accurately arranging seedling storage cells in opposition to seedling pushing rods irrespective of the transporting tilt of the seedling tray. In the method, the seedling tray formed with a plurality of seedling storage cells is positioned at a predetermined position by means of tray positioning rods, and the seedling pushing rods are inserted into respective seedling storage cells while maintaining the positioned condition. The device implementing the method includes the tray positioning rods for positioning the seedling tray at the predetermined position and the seedling pushing rods for performing an inserting operation for respective seedling storage cells while maintaining the positioned condition of the seedling tray by the tray positioning rods.
