4b), it is configured to facilitate relocation and movement of the plant and to facilitate cleaning after the work is completed.

This embodiment is constructed as described above, and its operation will be described below with reference to the flowcharts of FIGS.

When the automatic button switch (50) is turned on, the driving of the conveyors (4), (7), (9) by the motors (19), (25), (40) is started, and the tray (3) is turned on. When the tray (3) reaches the position of the first switch (42) and the switch (42) detects this, the motor (20) drives the tray (3) to fill the soil with the nutrient. Is performed, and the surface of the filled soil is leveled by the brush (12).
When the tray (3) passes through the position of the ejection device (13) after a predetermined time has elapsed since the switch (42) was turned on, pressurized air from the compressor (23) is ejected to the tray (3). Then, the gap between the upper end of the seedling raising box (2) and the upper end of the tray (3) is cleaned, and the subsequent detection of the pot (3a) by the sensors (47) and (48) is ensured. Can be.

Further, when the tray (3) passes through the position of the irrigation device (14) after a predetermined time has elapsed since the switch (42) was turned on, spraying and irrigation is performed on the surface of the filled soil, and the tray (3) ) Reaches the position of the switch (43), which is the feed end position of the conveyor (4), and this state is detected. The switch (44) is off, and the tray ( When the seeding is completed without 3), the tray (3) is inherited by the sowing conveyor (7) and sent to the sowing machine (8), and the switch is turned on to the sowing machine (8) position. In the seeding operation state having the tray (3) of the previous transport, the driving of the filling conveyor (4) is stopped, the standby of the tray (3) is performed, the work in the seeding machine (8) is completed, and the previous transport is completed. Tray (3) is switch ( 4) when moving from position to transport inherit again conveyor (4) seeding the conveyor tray (3) to start the drive (7).

Then, the tray (3) is conveyed to the pressure-reducing switch (47), and every time the switch (47) detects each pot (3a) of the tray (3), a depression for sowing is formed on the surface of the soil. The crushing operation for forming (A) is a crushing body (2)
6), the tray (3)
Is transferred to the seeding switch (48), and the switch (4)
Every time 8) detects each pot (3a) on the tray (3), in the case of one seed sowing, the transport of one sowing cycle (C) and the seed adsorption step as shown in the program of FIG. ) Is performed sequentially.

That is, at the position of the seeding switch (48), 1
When the seeding of the pitch pot (3a) is completed, the transfer of the tray (3) by the drive of the seeding conveyor (7) and the seed suction step by the operation of the nozzle (30) are performed simultaneously in parallel, and the next pitch pot (3a) ) Switch (48)
Is detected, the seed (B) is released by setting the state in which the seed adsorption step in the nozzle (30) is completed in accordance with the stop of the transport of the tray (3).
The work time required for one cycle (C) of the sowing can be greatly reduced as compared with the case where the transporting step of the tray (3) and the step of adsorbing the seed (B) are separated. In this case, in the case of sowing two grains, the seed adsorption / release step is performed twice in one cycle (C).

The seeding operation for the pot (3a) for each pitch is completed, the tray (3) is inherited by the soil covering conveyor (9), and the tray (3) is transported to the position of the earth covering machine (10). When the switch (45) detects that the soil has been seeded, soil cover is sequentially applied to the surface of the soil after seeding, and then the tray (3) is transported to the irrigation device (38). After a lapse of time, spraying and watering is performed on the surface of the soil cover, and when the switch (46) detects that the tray (3) has been transported to the feed end of the conveyor (9), the drive of the conveyor (9) is stopped. At the same time, after the elapse of the predetermined time, the alarm buzzer (53) operates to notify the operator of the alarm buzzer.

When the cycle switch (51) is turned on other than during the automatic control as shown in FIG. 7, only one cycle (C) of the seeding described above can be performed. Thus, it is possible to easily confirm the adsorption of the seeds to the nozzle (30) and to check the height of the nozzle (30) in advance, and to perform an efficient operation without losing the seeds (B).

Further, when the cycle switch (51) is turned off during the automatic control, as shown in FIG. 8, the seeding cycle (C) step is temporarily stopped, and it is easy to confirm the seeding during this operation. It can be done.
