A sensor 36 is attached to the attachment arm 32.
The sensor 36 is biased to either the left or right side of the transfer table 1. The sensor 36 is connected to the control box 26 by a connecting cord 37. sensor 36
is turned off when the seedling raising box 2 comes into contact with the control box 26.
The electric circuit inside stops the motor 5,
Also, the solenoid valve 27 is closed. The control box 26 has a socket 38, a socket 39, and a socket 40,
Connect the cord 43 of the motor 5 to the socket 39. 41 is a mounting bracket for the control box 26, and 42 is a power cord.

(effect) Next, we will discuss the effect.

The sensor 36 of the present invention has a detachable mounting arm 3.
2, fix the mounting arm 32 to the transfer table 1 with screws, etc., attach the control box 26 to the transfer table 1 with the mounting bracket 41, and connect the power cord 4.
The installation is completed by connecting the connection cord 37 of the sensor 36 to the socket 38 of the control box 26, and the cord 43 of the motor 5 to the socket 39 of the control box 26.

When the seedling raising box 2 is not in contact with the sensor 36, the motor 5 is on and the solenoid valve 27 is open, so the transfer table 1, the seed supply device 29, and the covering soil supply device 30 are operated by the motor 5. The irrigation device 8 sprinkles water. Therefore, when seedling raising boxes 2 filled with bed soil are supplied one after another without any gaps to the starting end side 6 of the transfer table 1, the seedlings are irrigated as they pass under the watering pipe 9 and pass under the seed supply device 29. When passing under the soil covering supply device 30, it is covered with soil.

The water that has passed through the connecting hose 28 -> electromagnetic valve 27 -> water supply hose 25 -> intermediate pipe 21 -> suction part 10 is then sprayed into the seedling nursery box 2 from the watering pipe 9, but at that time, the water is sprayed from the suction pipe based on the principle of misting. 18, the solution 20 is inhaled and the solution 20 is sprayed at the same time as irrigation.

The amount of water discharged from the sprinkler pipe 9 can be determined from the scale of the water pressure gauge 23.

The seedling raising box 2 is transferred without any gap from the starting end side 6 toward the terminal end side 7, and is taken out laterally at the terminal end side 7.
Since the guard body 31 is not provided for the length of
It can be taken out simply and easily.

However, in some cases, the taking out operation may not be completed in time, and conventionally the seedling raising box 2 has been dropped, but in the present invention, a sensor 36 is attached to the terminal end, and the sensor 36, the solenoid valve 27 and the motor 5
When the seedling box 2 comes into contact with the sensor 36 and turns on, the solenoid valve 27 closes and the motor 5
are connected so that they stop, so there is no risk of this happening.
