A guide member 29 is provided via a bracket 41 at the front end of the frame 26 in the conveying direction of the seedling box 7. The guide member 29 is formed by bending an angle material or a plate material, and has a cross-sectional shape (L shape) to form one reflecting surface 29a.
The guide member 29 is welded with a round bar at one end edge to form left and right support shaft portions 29b. The left and right support shaft portions 29b are inserted into the holes of the bracket 41, and the guide member 29 is rotated about the horizontal axis. Support freely and change posture.
The guide member 29 is formed with notches 29c in the vicinity of the support shaft portions 29b at both left and right ends, and the free end side away from the support shaft portion 29b protrudes left and right to form a contact portion 29d. When 29 is turned upward, the contact portion 29d contacts the bracket 41 or the frame 26, and the reflection surface 29a is set to face the front roller 34.

The posture where the reflecting surface 29a faces the front roller 34 is a floor soil reflecting posture A (right side in FIGS. 1 and 2) in which the soil dropped from the conveyor belt 36 collides and reflects to the rear side. Occasionally used, the soil is reflected by the reflecting surface 29a, so that the large grain soil is scattered far away and the small grain soil is scattered nearby, and the seedling box 7 is filled with the large grain soil leading to the bottom. Then, the small-sized soil is filled on the filled large-sized soil, and an optimum filling state is obtained for the lower-layer large-sized upper-layer small-sized floor soil.
When the guide member 29 is rotated downward, the left and right cutouts 29c face the inner surface side of the bracket 41 and are suspended by their own weight.

The state in which the guide member 29 is in sliding contact with the upper surface of the peripheral wall of the seedling box 7 is a box guide posture B (left side in FIGS. 1 and 2), and the weight of the guide member 29 used and pushed away is added to the seedling box 7. Thus, the vertical movement of the nursery box 7 can be regulated by the weight, and seeds, soil, and the like placed on the upper surface of the peripheral wall can be eliminated by sliding contact.
Since the guide member 29 has a U-shaped cross section, the reflecting surface 29a is in a substantially vertical state in the box guiding posture B, and therefore the edge 29e is in sliding contact with the upper surface of the seedling box 7, so that the seeds on the upper surface of the peripheral wall, Soil etc. can be removed more reliably.

When the guide member 29 is rotated upward to the floor soil reflection posture A, the guide member 29 acts as a soil guiding means for guiding the soil to the seedling box 7 in the lower layer large grain upper layer small grain state. Since the soil guiding means is unnecessary when supplying the soil covering, when the guide member 29 is rotated downward, that is, when the action of the soil guiding means is released to the box guiding posture B, the vertical movement of the seedling box 7 is restricted. It acts as a box guiding means that slidably contacts the upper surface of the peripheral wall of the seedling box 7.
