[0022]

[Operation] Next, the operation will be described. (Individual state) The starting end side transfer stand 38 and the terminal end side transfer stand 67 are connected by an arbitrary means, and the frame 1 of the seedling raising box automatic supply device 11 is connected.
3, the seedling raising boxes 7 are stacked on top of each other, the soil is put into the supply hopper 26 of the floor soil supplying device 25, and the hopper 5 of the seed supplying device 56.
7, the seed is supplied, and the supply hopper 6 of the soil cover supplying device 60
Prepare soil by supplying soil to 1.

Then, for example, the tension clutches 34 and 70 of the soil cover supplying device 60 and the floor soil supplying device 25 are disengaged, and among the switches of the operation switch box 75, the floor of the transfer and soil supplying motor 37 of the starting side transfer table 38. If only the soil switch 80 and the soil cover switch 83 of the soil cover motor 74 are turned on and all other switches are turned off and the main switch 85 is turned on in this state, the transfer / soil supply motor 37 and the transfer / soil cover 74 Is energized and the transfer rolls 2 of the start side transfer table 38 and the end side transfer table 67 are operated, so that each part of the transfer table 1 is inspected.

Next, in this state, the seedling raising box supply switch 7
When 9 is turned on, the motor 17 of the automatic nursery box feeder 11 operates to supply the seedling raising boxes 7 one by one to the starting end side transfer table 38 from the automatic seedling box feeder 11, and the nursery box 7 starts at the starting side 5 Since it is transferred from the terminal side 6 to the terminal side 6, adjustment of guide guides and the like (not shown) is performed to check whether the transfer of the seedling raising box 7 is carried out reliably.

When the tension clutch 34 and the tension clutch 70 are turned on while the automatic nursery box feeder 11, the start side transfer table 38 and the end side transfer table 67 are in operation, the rotation of the transfer roll 2 is transmitted. The bed soil supply device 25 and the soil cover supply device 60 are operated to supply the soil bed and the soil cover to the seedling raising box 7 being transferred. Therefore, the supply amount, the supply state, the leveling state by the rotating brush, and the Although not shown, the pressure of the soil under pressure by the pressure roller is checked. In this case, since the sieve soil used for the bed soil supply device 25 and the soil cover supply device 60 is not supplied with irrigation and seeds, it should be recovered from the seedling raising box and returned to the bed soil supply device 25 and the soil cover supply device 60, respectively. When the soil used is different between the bed soil supplying device 25 and the soil covering supplying device 60, they are individually checked and then recovered from the seedling raising box and returned to the original state.

Then, the tension clutch 34 and the tension clutch 70 are disengaged, the floor soil supplying device 25 and the soil covering supplying device 60 are stopped, the seedling raising box 7 is transferred by the seedling raising box automatic feeder 11, and the valve switch 81 is used. Is turned on to open the opening / closing valve 55 to check the adjustment of the irrigation amount by the flow rate control valve 92 of the irrigation device 53, and then to stop the irrigation device 53 to check the seed feeding amount of the seed supply device 56. To do.

In this case, since the switches of each device are provided in the operation switch box 75, it is only necessary to stand by the operation switch box 75 and turn on / off each switch.
You can check it and it's very easy.

Since each device is provided with a switch, if the main switch 85 is turned on, the switch of each device can be operated, and the device can be stopped and operated in two places. , Operability is improved.

(Interlocking state) Next, again, the seedling raising boxes 7 are stacked on the frame 13 of the automatic seedling raising box feeder 11, and soil is put into the feed hopper 26 of the floor soil feeder 25 to seed the seeds. The seeds are supplied to the hopper 57 of the supplying device 56, the soil is supplied to the supplying hopper 61 of the soil cover supplying device 60 to prepare for the operation, and the changeover switch 86 of the operation switch box 75 is switched to "interlocking", and the seedling raising box supply switch. When the main switch 85 is turned on in a state where all the switches from 79 to the soil cover switch 83 are turned on, the respective devices are energized all at once, and the seedling raising box 7 is transferred to the transfer table 1 by the seedling raising box automatic supply device 11.
The seedling raising box 7 which is being supplied and is being transferred is supplied with the bed soil by the bed soil supply device 25, is watered by the irrigation device 53, is supplied with the seed by the seed supply device 56, and is covered with the soil cover supply device 60. The soil is covered and the seeding is completed.

When the changeover switch 86 is "interlocked", if any one of the nursery box supply switch 79 to the soil cover switch 83 is turned off, not only the device corresponding thereto but also the start end side 5 from this device. For example, when the seed switch 82 is turned off when the seed paddy in the hopper 57 of the seed feeding device 56 is exhausted, the seed switch 82 causes the seed feeding motor 58 of the seed feeding device 56 to stop. Not only the seed supply device 56 but also the irrigation device 53, the bed soil supply device 25, the seedling box automatic supply device 11, and the start end side transfer table 3 which are located on the start end side 5 of the seed supply device 56.
8 is automatically stopped and the state in which seeds cannot be supplied is immediately stopped, and the transfer / soil-covering motor 74 of the terminal side transfer stand 67 on the terminal side 6 of the seed supply device 56 is operated and the seeds are already seeded. The seedling raising box 7 which has been supplied is transferred as it is, the covering soil is supplied by the covering soil supplying device 60 and then taken out at the terminal side 6, the whole is stopped by the main switch 85, and the seeds are put in the hopper 57 of the seed supplying device 56. When the main switch 85 is turned on after replenishing the supply, each device is operated and the work is restarted (in this case, even if the seed switch 82 is turned off, the transfer and soil covering motor 74 of the terminal side transfer stand 67 does not stop. When the seed switch 82 is turned off, the transfer of the seedling raising box 7 that has already been transferred to the terminal side transfer stand 67 cannot be stopped, but after that, the seedling raising box 7 is transferred from the start end side transfer stand 38. Since not transported, the seed feed device 5
The damage caused by the suspension of 6 can be minimized).

Similarly, when an accident such as clogging of the irrigation pipe 54 of the irrigation device 53 occurs and the valve switch 81 is turned off to close the opening / closing valve 55, the soil supply on the starting end side 5 of the irrigation device 53 is supplied. The device 25, the seedling box automatic supply device 11, and the starting end side transfer stand 38 are stopped.

Further, the seedling raising boxes 7 supplied with the soil covering by the soil covering feeding device 60 are sequentially taken out at the terminal end side 6. However, this taking-out work fails, and the seedling raising boxes 7 reach the detecting section 88, and the detecting section 88 detects that. When the effect is detected, all the devices are stopped.

However, the soil replenishing device 43 turns off the soil replenishment switch 84 when the supply hopper 26 of the floor soil replenishing device 25 becomes full, and stops replenishing the soil to the floor soil replenishing device 25. Even in the state, the soil replenishment switch 84 can always be turned off independently. In this case, even if the soil replenishment switch 84 is stopped, other devices are not interlocked and stopped, but they are stopped by the switch of the other device. When it stops, it stops.

Therefore, in the second embodiment, the switch of the transfer / soil cover motor 74 for operating the soil cover supply device 60 is also used as the main switch 85, and the soil cover supply device 60 is operated.
When an accident occurs in, the main switch 85 is turned off. That is, when there is an accident in the soil cover supplying device 60, all the subsequent nursery boxes 7 are stopped, and there is no nursery box 7 that can be taken out. Therefore, by operating the main switch 85, other devices are simultaneously operated. The main switch 85 is also used to stop and restore.

(Other functions) Since the operation switch box 75 is provided in the space between the motor box 76 attached to the rear side of the soil cover feeder 60 and the rear plate 73 of the feed hopper 61, the space can be effectively used. Available and does not disturb the inspection of other parts. Also, the operation switch box 7
Since the rear plate 77 of 5 faces the rear side, it can be operated from either side of the transfer table 1. . Further, since the operation switch box 75, the motor box 76, and the valve box 87 of the opening / closing valve 55 are integrally attached, the assembly becomes easy.
