A warning lamp LMP is provided as a means for giving warning,
When moving the seedling box storage frame T of the feeding device A, the seedling box is collected.
State spanning the container frame T side and the seedling box feed guide section 30 'side
Warning that the seedling box storage frame T cannot be moved when
A report buzzer-BEEP is provided. In the seedling box storage frame T
When all the seedling boxes are not replenished
Automatic stop device STP is provided as a means to automatically stop
(The specific configuration of the automatic stop device STP is known technology.
Therefore, it is omitted here). And the above various switches

And alarm lamp LMP and alarm buzzer-BEEP as output system
And a control device CNT as a means for controlling these inputs and outputs.
L is provided. The spare seedling supply device A configured as described above
Is controlled and operated as follows (see FIGS. 9 to 16). Immediately
The key switch for starting the vehicle body 2 is turned on.
First, the start switch ASw is in the off state.
At this time, the seedling box is placed on the seedling box storage frame T side and the seedling box feeding guide portion 30 '.
(SW1 = OFF and SW2 = OF
F), the movement of the seedling box storage frame T is not possible.
The alarm buzzer BEEP for alarming the active state is activated.
When the alarm BEEP is activated, the seedling box storage frame T and the seedling box are sent.
Take out the seedling box straddling the guide section 30 'side and reset it.
Press the switch RSw. In addition, the seedling box and the seedling box storage frame T side
In the state of straddling the seedling box feed guide section 30 '
Also, if there is a seedling box downstream from it (NSw = ON),
Since the planting can be started in that state, the alarm BEEP does not operate.
No. Next, the alarm is not activated and the seedling box housing frame T is moved.
When the movable state is detected, the seedling box storage frame T
Actuated to move to the location (Sabourtin SHIFT,
(FIG. 16-P3). Here, the motor M (48) operates.
Then, the pinion gear 49 rotates right or left and the rack 47
Move horizontally to the right or left, and set it at the left and right center position of the rack 47
The left and right center positions are fixed to the left and right center positions of the fuselage.
When the switch contacts the position detection switch SWC and turns on,
-M (48) is stopped and the seedling box storage frame T is centered on the left and right.
It is designed to move to a position. Seedling box T is horizontal
The row is 6 boxes wide, so the seedling planting section 4
For transportation and storage
When not working, etc., if you position it in the center of the left and right,
It is efficient because it can be minimized. Next, the center movement of the seedling box housing frame T is completed.
And the control unit CNTL waits for the start switch ASw to turn on.
Transition to the state. In this state, move the aircraft to the field
You. And when it is ready to start seedling transplantation work,
The pilot presses the start switch ASw. Start switch AS
When w is switched to the ON state, the control device CNTL
Transfer to control. First, the seedling box housing frame T shifts to the left.
