The individual pot 2 in the seedling box 1 has a rectangular or hexagonal cylindrical shape by developing paper or a thin film such as paper, and is disclosed in Japanese Patent Publication No. 58-11817 and Japanese Patent Publication No. 4-79612. In the same manner as described in Japanese Unexamined Patent Application Publication No. H10-205, the parts are connected by connecting pieces (not shown). In the seedling box 1, an aggregate 3 in which continuous pots formed by connecting the individual pots 2 with connecting pieces are adhered with water-soluble glue and densely assembled is expanded in a honeycomb shape using an expansion frame 4. Has been stored. FIG. 4 to FIG. 7 show a procedure for expanding and storing the aggregate 3 in the seedling box 1 and a storage state.

The developing frame 4 is formed in a rectangular shape in conformity with the contour of the upper edge of the seedling box 1. The unfolding frame 4 is formed by joining a pair of short edge frames 5 disposed on opposite short sides of the rectangle and a pair of long edge frames 6 disposed on opposite long sides to each other. Is provided as As shown in FIG. 4, each short edge frame 5 is associated with a plurality of comb-like claw pieces 7 that can be inserted into the individual pots 2 located outside the assembly 3 and the outer edge of the seedling box 1. And an engagement piece 8 that can be engaged. When a plurality of individual pots 2 on one side of the flat assembly 3 are hooked on the nail pieces 7 of one short edge frame 5 and the other side of the assembly 3 is pulled toward the other short edge frame 5, the assembly is performed. As shown in FIG. 5, the body 3 is fully developed in a honeycomb shape in the development frame 4, and a plurality of the individual pots 2 on the pulled side are hooked on the claw pieces 7 of the other short edge frame 5 as they are. The honeycomb state is maintained. Then, after the assembly 3 is expanded by the deployment frame 4, if the development frame 4 is placed on the seedling box 1 with the assembly 3 on the lower side, the entire assembly 3 will fit in the seedling box 1. When the developing frame 4 is put on the seedling box 1, the engaging pieces 8 of the pair of short edge frames 5 of the developing frame 4 are fitted into the seedling box 1, whereby the seedling box 1 and the developing frame 4 The position is fixed relative to the transport direction A.

Thus, the pair of long edge frames 6 constituting the developing frame 4 are left and right so that their outer surfaces are in sliding contact with the upright walls 34 of the left and right guide members 32 provided on the conveyor 10. The interval is set. On the other hand, the mutual interval between the standing walls 34 of the left and right guide members 32 is set to be larger than the width of the largest seedling box among a plurality of types of required seedling boxes 1. That is, the distance connecting the outer side surfaces of the pair of long edge frames 6 of the development frame 4 is larger than the maximum width of the seedling box 1. Therefore, the aggregate 3
When the developing frame 4 is put on the seedling box 1 in order to accommodate the seedlings, the left and right long edge frames 6 of the developing frame 4 protrude to both sides of the seedling box 1 of all kinds (all sizes). Thus, when the seedling box 1 is placed on the conveyor 10, the left and right long edge frames 6 of the unfolding frame 4 always keep the left and right guide members 3.
The second standing wall 34 comes into sliding contact with the second standing wall 34.

When the seedling box 1 containing the aggregates 3 is placed on the roll 24 on the rear side of the conveyer 10 in the soil filling sowing apparatus configured as described above, the left and right long sides of the development frame 4 are elongated. The edge frame 6 is fitted between the upright walls 34 of the left and right guide members 32, and the position of the continuous pot assembly 3 fixed by the plurality of claw pieces 7 of the development frame 4, ie, the position of the individual pot 2, is a conveyor. Positioning is accurate in the width direction. In this state, one of the feed hitches 31 comes into contact with the rear end of the seedling box 1 by rotation of the chain 29 of the conveyor 10, and the seedling box 1 is sent out in the transport direction A. At this time, the left and right long edge frames 6 of the developing frame 4 slide along the surface of the upright wall 34 of the left and right guide member 32, and the seedling box 1 slightly moves in the conveyor width direction. Since the individual pots 2 in 1 are positioned on the basis of the development frame 4, the position in the conveyor width direction is floating.

In this way, the seedling box 1 containing the continuous pot aggregate 3 is conveyed, and the seedling box 1 is first supplied with a predetermined amount of cultivation soil 11 by the earth filling machine 12 and then sowing. A sowing bed is formed by the floor forming machine 13, and the seeds 14 are supplied to the individual pots 2 by the sowing machine 15. At this time, since the position of the individual pot 2 in the seedling box 1 is accurately positioned in the width direction of the conveyor, the seeding by the sowing machine 15 is performed accurately at the center of each individual pot 2.

A material having excellent sliding properties, for example, a fluororesin-based coating may be provided on the outer surface of the long edge frame 6 of the developing frame 4, so that the sliding of the developing frame 4 can be smoothly performed. In addition, the life of the deployment frame 4 is extended.

[0021]

As described above in detail, according to the soil filling apparatus according to the present invention, the individual pots in the seedling box are moved in the width direction of the conveyor with respect to the deployment frame for deploying the continuous pot aggregate. , It is not necessary to change the arrangement according to the change of the seedling box, which greatly contributes to the improvement of productivity. When a chain conveyor is used as the conveyor, the cover of the chain can be used as a guide for guiding the deployment frame as it is, and the number of parts does not increase, which is extremely advantageous in terms of cost.
