作動が極めて短時間に完了する。The soil-covering device 12 is provided with a soil-covering hopper 53 for storing the soil in the upper portion, 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 nursery box 1 on the conveyor 2 is transferred in the direction of arrow 7 and enters below the nursery bed filling device 4 of the nursery bed 3. When the nursery box 1 reaches a position where it blocks the light beam of the phototube 18, the control circuit operates.
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 supporting device 20 also moves in the direction of arrow 29, and the piercing body 27 falls through the hole 28 of the case 17. The second and third sheets on the bottom seedbed 3 to be pierced are pierced and supported to prevent falling. At the same time, when a current flows through the solenoid 25 and the plunger 26 is pulled in the direction of the arrow 24, the feeding claw 19
Is opened to the outside, the seedbed 3 at the bottom is dropped and stored in the seedling raising box 1 below. Next, the solenoid 25 of the feeding claw 19
, The plunger 26 returns to the direction of the counter arrow 24, the feeding claw 19 returns to its original position, and the waiting state for the upper stacked seedbeds 3 to come down is waited. Then, when the current of the solenoid 30 of the supporting device 20 is cut off and the plunger 31 returns to the direction opposite to the arrow 29, the piercing body 27 comes out of the seedbed 3 and releases the support, so that the stacked seedbed 3 is transferred to the feeding claw 19. The operation of one cycle of the seed bed filling device 4 by the sequence control circuit is completed in an extremely short time after reaching the supported position.

The lower part 32 of both side walls of 7 is very close to the width of the nursery box 1 and regulates its position.
Since the position is also regulated, if it falls, it will be accommodated within the width of the nursery box 1 without difficulty. On the other hand, as a method for accommodating the nursery box 1 in the traveling direction, the nursery bed filling device 4 may be operated and accommodated in a timely manner with respect to the nursery box 1 traveling at a constant speed. The nursery 3 has a transfer arrow 7 for the nursery box 1
It may be dropped at an appropriate time so that it is supported by the upper edge of the direction front end and the inner bottom surface of the box 1. At this time, as the advancement of the nursery box 1 progresses, the front end of the nursery bed 3 collides with the upper edge 34 of the opening at the lower side wall of the outlet of the case 17 and is received. Are relatively slid and accommodated and filled in the nursery box as shown in FIG. 5 (b).

る。When the brush 35 is provided so as to hang down, the brush 35 impresses the upper surface of the seedbed 3 housed in the seedling raising box 1 until the seedling raising box 1 exits below the seedbed filling device 4. Therefore, the completeness of filling can be increased. And, in particular, in the seedbed filling device 4 for supplying the plate-shaped seedbed 3 to the seedling raising box 1 transferred by the conveyor 2, the seedbed filling device 4 should be fed out one by one from the bottom of the stacked seedbeds 3, Provide a feeding device configured to support the seedbed 3 above the lowermost seedbed 3 by the piercing body 27 that pierces the side wall of the lowermost seedbed 3 so as not to fall when the lowermost seedbed 3 is fed out. So pierced body 27
Pierces the side wall of the nursery 3 above the lowest nursery 3,
The seedbeds 3 above the bottommost seedbed 3 can be accurately supported so as not to fall, and the seedling boxes 1 that are sequentially transferred by the conveyor 2 are continuously stacked one by one accurately without stopping. Can be supplied to, and work efficiency is greatly improved.
