In addition, if the amount of soil covered in the soil covering tank (32) is insufficient and this is alarmed by the lower level meter (43), only the second two-prong damper (15) is switched and each damper [141+151 is passed through the third conveyor The feed end of (12) is connected to the feed start end of the sixth conveyor (31), and the sorted surface carried out by the third conveyor (12) is transferred to the sixth conveyor (31) via each damper (141 + 151) and covered with soil. Carry it into the tank (32).

Furthermore, 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).
6) and the culture medium (on sorting) taken out from the chemical tank (17), fertilizer, etc. are mixed in a set ratio by a ribbon mixer (20) to form a bed, and the horizontal damper (21) is opened and closed to mix the culture medium (on sorting) and fertilizer, etc. ) onto the floor of the hopper (22), and the rotary dresser (25) is moved onto the floor of the hopper (22) by the fourth and fifth conveyors (23) (24).
The floor surface finished by the dresser (25) is stored in an above-floor tank (26), and the floor surface is transferred from the tank (26) to a soil filling machine (28), and from the tank (32) to a soil covering machine (30). In addition to supplying covering soil to each area, a seeding table (
The seedling raising box (al) is continuously moved by driving each part of the seedling raising box (27), and the seeding work is performed continuously.

In addition, as mentioned above, the seedling raising box after sowing is loaded on the seedling raising cart, and is placed in the budding chamber (4) and the first and second greening chambers (5).
(Sequentially moved to 61 to perform seedling raising work.

In addition, during the seeding work, when the bed soil is put into the seedling box fal that moves downward by the soil filling machine (28) and the bed leveling work is performed to level the top of the bed to a uniform thickness, the top of the bed is leveled. As a result of the work, the surplus floor that leaked from the seedling box [al] fell down to the soil container ffl +281, and the hopper (35)
The surplus floor that falls to the feed start end of the seventh conveyor (33) is conveyed to the floor hopper (36) via the seventh and eighth conveyors (331 (341), and the surplus floor is transferred to the fifth conveyor ( 24), it is transported again to the rotary dresser (25) and returned to the floor tank (26).
