2. Description of the Related Art When a tray guide for vertically guiding a seedling tray is provided on the lower end side of the seedling mounting table in the vertical feeding direction, the working surface of the tray guide is slid on the outer peripheral surface of the cell at the bottom of the seedling tray. The vertical feed guidance is provided in contact with each other.

[0003]

However, when the seedlings at the left and right outermost ends of the seedling tray have stems and leaves protruding outward due to stem deformation, etc., the tray guide and other accessory parts of the seedling mounting table should be used. There was a problem that the tray guide could not be smoothly entered due to being caught or the like, resulting in poor seedling removal, damage to the foliage, and poor vertical feeding.

[0004]

Therefore, according to the present invention, in a structure in which a tray guide for guiding the vertical feeding of the seedling tray mounted on the seedling mounting table is provided on the lower end side of the vertical feeding of the seedling mounting table, the vertical direction of the seedling tray is provided. With respect to the feeding direction, the rear end of the tray guide is made to face the lower part of the seedling tray, and the middle part of the tray guide is formed to be upwardly inclined so that the front end of the tray guide is made to face the upper part of the seedling tray. With the guidance of the guide, the seedlings are smoothly fed vertically without damaging the foliage, and highly precise seedling removal work that does not cause defective feeding of the seedlings or poor seedling removal is performed.
