Description of the Related Art As a conventional technique of this kind, as shown in Japanese Utility Model Laid-Open No. 58-170911, an operator fills a nursery box with a plate-shaped nursery formed of foamed polyurethane or paper material. Then, one of them is supplied one by one onto the conveyor on the upstream side in the transfer direction of the seeder. Therefore, since the nursery box was manually filled with the plate-shaped nursery and supplied on the conveyor, the work efficiency was very low.

い。The soil-covering device 12 is provided with a soil-covering hopper 53 for storing the soil in the upper part, a feeding conveyor 43 for feeding the soil in a fixed amount, and a transmitting device 45 for the conveyor 43 in the lower portion. Power is transmitted from the motor 41 as described above. Next, the operation will be described. First, a large number of stacked seedling raising boxes 1 are sequentially dropped by the spiral 15 from the bottommost one onto the delivery roller conveyor 16 below. Since the roller conveyor 16 is inclined in the direction of the conveyor 2, the seedling raising box 1 is delivered onto the conveyor 2 by its own weight. The seedling raising box 1 on the conveyor 2 is transferred in the direction of arrow 7 and enters below the feeding device 4 of the seedbed 3. Seedling box 1 is photoelectric tube 1
The control circuit operates when it reaches the position where the light beam of 8 is blocked. First, when a current flows through the solenoid 30 of the supporting device 20 and the plunger 31 moves in the direction of arrow 29 by the action of the electromagnet,
The support device 20 also moves in the same direction as the arrow 29, and the needle 27 tries to fall through the hole 28 of the case 17 at the lowermost nursery bed 3.
The second and third sheets above are pierced and supported to prevent falling. At the same time, when a current flows through the solenoid 25 and the plunger 26 is attracted in the direction of the arrow 24, the feeding claw 19 opens outward and the seedbed 3 at the bottom drops to be stored in the seedling raising box 1 below. Next, the current of the solenoid 25 of the feeding claw 19 is cut off, the plunger 26 returns to the direction of the counter arrow 24, the feeding claw 19 returns to the original position, and the stacked seedbeds 3 on the upper side are returned.
Is waiting for you to come down. Subsequently, the current of the solenoid 30 of the supporting device 20 is turned off, and the plunger 3
When 1 returns to the direction of the anti-arrow 29, the needle 27 comes out of the nursery bed 3 and releases the support, so that the stacked nursery beds 3 descend to the position supported by the feeding claws 19 and the feeding device 4 of the sequence control circuit 1 The operation of the cycle is completed in a very short time. Instead of the needle 27, another pressure supporting method may be used.

（ｂ）のように育苗箱内に収容充填される。When the nursery bed 3 is dropped by the above-described operation of the nursery bed feeding device 4, the lower side walls 32 of the case 17 are extremely close to the width of the nursery box 1 and regulate the position thereof, as shown in FIG. The position of the nursery bed 3 is also restricted by the stepped portion 33 on the upper part, so if it falls, the nursery box 1 can be comfortably operated.
Accommodated within the width of. On the other hand, the method for accommodating the nursery box 1 in the traveling direction is as follows:
The feeding device 4 may be operated and accommodated at a proper time, but as shown in FIGS. 5 and a, the seedbed 3 is supported by the upper edge of the front end of the nursery box 1 in the direction of the transfer arrow 7 and the inner bottom surface of the box 1. You may drop at such a suitable time. At this time, if the progress of the nursery box 1 progresses,
Since the front end of the nursery bed 3 abuts against and is received by the upper edge 34 of the opening on the lower side wall of the outlet of the case 17, the nursery bed 3 and the nursery box relatively slide as the nursery box 1 is transferred.
As shown in (b), it is contained and filled in the nursery box.

Since the brush 35 impresses the upper surface of the nursery 3 housed in the nursery box 1, the completeness of filling can be increased. The seedling raising box 1 thus filled with the seedbed 3 in the feeding device 4 is irrigated by the pre-irrigation device 9 to the extent that the seedbed 3 is moistened to improve seed implantation, and seeds are sown by the seeding device 10, and further seeded. After irrigating the seeds and the plate-shaped nursery bed 3 with a sufficient amount of water by the post-irrigation device 11, the soil covering device 12 covers the seeds with the soil required for germination and nursery, and the seedlings are grown in a nursery room. Be used for.
