The end of the feed is connected to the start end of the sixth conveyor (31), and the sorting surface to be carried out by the third conveyor (12) is connected to the sixth conveyor (31) via each damper [141 (15)].
The soil is then transferred to the soil-covering tank (32).

Further, when the fertilizer and pesticides in the chemical tank (17) are insufficient, only the most forked damper (14) is operated to switch the feeding end of the third conveyor (12) to the chemical tank (17).
7), put the fertilizer and pesticides in the potting soil type (2) into the chemical input hopper (13), and transfer the fertilizers and pesticides to the third tank.
The chemical is transported by a conveyor (12) via a damper (14) to a chemical tank (17), and the soil is transported into a chemical tank (17) by a conveyor (12).
A ribbon mixer (20) mixes the culture medium (on sorting) and fertilizer taken out from the chemical tank (17) to form a bed, and then opens and closes the horizontal damper (21) to ) is dropped onto the floor of the hopper (22), and the bed soil of the hopper (22) is transferred to the rotary dresser (25) by the fourth and fifth conveyors f23) f24+.
), the finished floor by the dresser (25) is stored in an above-floor tank (26), and the finished floor is stored in an above-floor tank (26).
The bed soil is supplied from the tank (32) to the soil covering machine (28), and the covering soil is supplied from the tank (32) to the soil covering machine (30), and each part of the seeding table (27) is driven to continuously feed the seedling boxes (al). It is moved and the seeding work is carried out continuously.

In addition, as mentioned above, the seedling box after sowing is loaded onto the seedling cart and placed in the budding chamber (4) and the first and second greening chambers +5).
Seedling raising work is performed by sequentially moving the seedlings to +61.

In addition, during the seeding work, when the bed is placed in the seedling box fal that is moved downward by the soil filling machine (28) and the bed soil is leveled to a uniform thickness, the bed is leveled. The surplus bed that has leaked from the seedling box (a) during flat work falls below the soil filling machine (28), and the surplus bed that falls to the feed start end of the seventh conveyor (33) via the hopper (35) is transferred to the third conveyor (33). 7 and 8 conveyors (F3) [34] to the floor hopper (36), and the excess floor is conveyed to the rotary dresser (2) by the fifth conveyor (24).
5) and then returned to the floor tank (26).
