  During seedling planting operation, the seedling transplanter revolves the vehicle body and has a large inclination, and supplies seedlings to the seedling tank while traveling in a state where a seedling box that contains seedlings in advance is mounted on the auxiliary seedling box stand. When performing, a seedling box stopper is often provided to prevent the seedling box from falling off the auxiliary seedling box support. However, if this seedling box stopper is protruded from the upper surface of the auxiliary seedling box receiving base, it is likely to become an obstacle when the seedling box is mounted and supplied.

  According to the first aspect of the present invention, a seedling box stopper 3 that locks the movement of the seedling box 2 is retracted against the spring 4 by mounting and feeding the seedling box 2 at one edge of the seedling box cradle 1. It is set as the structure of the auxiliary seedling box receiving apparatus of the seedling planting machine characterized by having provided. When a predetermined seedling box is previously mounted on the upper surface of each seedling box receiving base 1 in order to perform seedling planting work of the seedling planting machine, when the supply end of this seedling box 2 is pressed against the seedling box stopper 3, the spring is thereby moved. The stopper 3 protruding from the upper surface of the seedling box cradle 1 is retracted by the four forces and is moved deeply into the seedling box cradle 1 deep inside the seedling box 2 and guided to a predetermined position. When the seedling box 2 is placed on the top surface of the seedling box receiving base 1, the seedling box stopper 3 is returned and protruded by the force of the spring 4, and one side end of the containing seedling box 2 is locked, so that the vehicle body is largely inclined and swings. Even so, the seedling box 2 is prevented from falling off.

  According to the first aspect of the present invention, when the heavy seedling box 2 is mounted and supplied on the auxiliary seedling box cradle 1, the tip of the seedling box 2 is pressed against the seedling box stopper 3 so that the spring 4 is elastic. The seedling box stopper 3 can be retracted against the force and the feeding of the seedling box 2 onto the seedling box cradle 1 can be facilitated. Further, when the seedling box 2 is placed on the upper surface of the seedling box receiving base 1, the seedling box stopper 3 protrudes by the force of the spring 4 to lock the end of the seedling box 2, thereby preventing the escape movement and dropping. The seedling box 2 can be mounted and supplied quickly and smoothly, and workability can be improved.
