もより２層コンパクトにできる効果を有する。As described above, according to the present invention, the seedling platform is arranged at an angle with respect to the traveling machine body and is configured to be movable to the left and right in the direction of movement of the machine, and the seedling mat is placed on the surface side of the seedling platform in the left and right directions. It is formed so that it can be arranged in multiple rows, and on the back side of the seedling platform, a single rotating shaft is arranged longitudinally along the moving direction of the seedling platform.
The rotation support shaft is configured to rotate by an appropriate angle at the left and right moving end of the seedling platform, and a plurality of navy blue feeding shafts each having a mold wheel attached to the outer periphery are connected to the rotation support shaft for each of the seedling mat locations. are fitted so that they can rotate independently of each other, and a clutch mechanism is provided between each vertical feed shaft and the supplementary rotation support shaft to turn ON/OFF transmission of the rotational force of the rotation support shaft. Because it is set up,
This rotation support shaft can perform the two functions of supporting each vertical feed shaft and transmitting rotational force thereto, and can be made extremely compact in structure. In addition, if the mechanism and one-way feed hollow cam are placed on the hollow back surface of the protruding ribs for placing each seedling mat on the seedling stand, the diameter will be slightly larger than that of the vertical feed shaft. Because of these parts, it is possible to shorten the distance between the pivot shaft center and the rear surface of the seedling table, and also to reduce the diameter of the mold wheel, which has the effect of making the vertical feeding device as a whole two times more compact.
