Description

[Detailed Description of the Invention] The present invention relates to an automatic seeding device for seedling raising boxes.

The present invention is an automatic seeding device for seedling boxes that has a rational overall structure and is easy to handle.The seedling boxes are fed from the starting end to a position above the transfer table that transports the seedling boxes horizontally. A device, a bed soil supply device, a seed supply device, a covering soil supply device, and a watering device are provided, and each of the seedling box, bed soil, seed, and covering soil supply devices is equipped with an independent motor, and each motor is The structure is connected to a seedling box passage detection device provided near the soil-covering supply device so as to be energized only when the seedling box passes; The gist of the invention is to provide an automatic seeding device for a seedling box, in which a final detection device capable of detecting is attached, and the final detection device is connected in relation to a pump of the watering device and a motor for rotating a conveyor of the transfer table. be.

To explain with the drawing, 1 is a transfer table on which three types of conveyors 2, 3, and 4 are attached. The transfer table 1 has a horizontally long structure, and a seedling box feeding device 7 for feeding seedling boxes 6 is provided above the starting end 5 of the transfer table 1 . The supply device 7 is located above the conveyor 2.
A frame body 8 with an open top and bottom is attached. Approximately 10 to 20 seedling boxes 6 are stacked and introduced through the upper opening 9, and the conveyor 2 transfers the seedling boxes 6 to the lower part.
are taken out one by one and fed automatically. A conveyor 3 is provided following the conveyor 2. The conveyor 3 is also called a rapid conveyor, and is formed with a high rotation speed. A seeding conveyor 4 is provided following the conveyor 3. Seeding conveyor 4
The conveyor 3 rotates more slowly than the fast-forwarding conveyor 3, and is rotated by the motor 10. 11
is a belt. At the upper position of the conveyor 4, from the start end 5 side to the end end 12 side, there is a bed soil supply device 13, a watering device 14, and a seed supply device 1.
5', 15'', and a covering soil supply device 16 are provided.The bed soil supply device 13 includes a hopper 17 and a feeding belt 1.
8, and a motor 19 for rotating the belt 18 is attached near the motor 19. The motor 19 is rotated by a detection tool 20 that detects when the seedling raising box 6 approaches the bed soil supply device 13, and when the seedling raising box 6 passes under the feeding device 13, the detection tool 20 rotates. It stops due to the action of A water sprinkling device 14 is provided next to the bed soil supply device 13, but the water sprinkling device 14 is not supplied by water pressure from the tap water, but is equipped with a pump 21, which sprinkles water. The pump 21
is a detection tool 2 provided at the terminal end 12 of the transfer table 1.
2 and is relationally (electrically) coupled to. The detection tool 22 detects the seedling growing boxes 6 that have passed through the soil covering supply device 16, and does not work when the seedling growing boxes 6 are passing successively. 6 passes, it is activated and sends a signal to the pump 21 to stop watering. A seed supply device 15' provided next to the watering device 14,
Although only one hopper 15'' may be used, uneven sowing can be eliminated by using two units as shown in the figure.The devices 15' and 15'' have the same structure, and each hopper 2
3', 23'' and delivery rolls 24', 24'',
Further, each motor 25', 25" is provided. As in the case of the bed soil supply device 13, each motor 25', 25" is rotated by a detection tool 26', 26".
Stop again. A covering soil supply device 16 is provided next to the seed supply devices 15', 15''.
has a hopper 27 and a feeding belt 28, and is stopped from rotating by a motor 29 located nearby.
The motor 29 is stopped from rotating by a detection tool 30 provided near the soil covering supply device 16. Therefore, the motor 10 that rotates the conveyor 4
is connected to the detection tool 22 in relation to the seedling raising box 6.
passes through the covering soil supply device 16, the motor 1
0 stops rotation.

Since the present invention has the above-mentioned configuration, if 10 to 20 seedling growing boxes 6 are packed into the seedling growing box supplying device 7 and supplied one after another by replenishing them when they run low, only the lowest seedling growing boxes 6 will be transferred to the conveyor 2. The seedlings are sent out by the action of , transferred onto the rapid conveyor 3, and transferred onto the seeding conveyor 4 at a high speed. Since the conveyor 4 sends the seedling growing boxes 6 at a normal speed, the subsequent seedling growing boxes 6 sent by the fast-forwarding conveyor 3 catch up with the preceding seedling growing boxes 6, so that they are placed on the sowing conveyor 4 without any gaps. To prevent bedding soil, seeds, etc. from falling downward through gaps and being wasted by being plucked and transferred. When the seedling raising box 6 approaches a position near the bed soil supply device 13, the detection tool 20 detects this and sends a signal to the motor 19.
9 is energized to rotate the feeding belt 18, and the bed soil in the hopper 17 is supplied into the seedling growing box 6. At this time, the seeding conveyor 4 that sends the seedling boxes 6 is rotated by a motor 10, and the motor 10 is configured to be operated by a detection tool 22, but only at the time of starting work, the motor 1 is turned on by a manual switch.
0 to rotate the seeding conveyor 4, and similarly, the pump 21 of the watering device 14 is also energized to sprinkle water. As the seedling box 6 continues to move forward and passes below the seed supply devices 15' and 15'', each detection device 2
Feeding roll 2 rotated by 6′, 26″
4', 24'', and when passing under the soil covering supply device 16, the seeds are covered with soil by the action of the feeding belt 28 rotated by the motor 29 operated by the detection device 30. When the planned number of seedling boxes 6 are supplied from the seedling box feeding device 7, the conveyor 2 automatically stops, and when the last seedling box 6 passes, each detection tool 20, 26', 2
6″, 30 for each device 13, 15′, 15″,
16 are stopped one after another, and when the final seedling raising box 6 passes the soil covering supply device 22, the pump 21 of the watering device 14 and the motor 10 of the seeding conveyor 4 are de-energized by the detection device 22 and automatically stop. It is.

The present invention has the above-mentioned configuration, and in particular, a seedling box feeding device, a bed soil feeding device, a seed feeding device, a covering soil feeding device, and a watering device are installed from the starting end of the transfer table for horizontally transporting the seedling growing boxes. , a motor is independently attached to each of the seedling box, bed soil, seed, and covering soil supply devices, and each motor is connected in relation to a seedling box passage detection device provided near each feeding device. A final detection device capable of detecting passage of the final seedling-growing box is installed near the soil-covering supply device, and a final detection device capable of detecting passage of the final seedling-growing box is connected to the watering device. Since the automatic seeding device for seedling boxes is constructed by linking the pump and the motor that rotates the conveyor of the transfer table, it is possible to automatically sow the seedling boxes and at the same time automatically stop the operation with a rational configuration. It is something. In particular, the water sprinkler 14 of the present invention is
Since the pump 21 is used instead of water pressure from the tap, the water pressure can be kept constant and water can be sprinkled accurately. In this case, it would be possible to automatically stop the pump 21 with a detection device installed nearby, as with other supply devices, but the nozzles of the sprinkler device 14 usually have 4 to 4 nozzles.
There are about 6 of them lined up everywhere, so I stopped pump 2 midway.
1 cannot be stopped, and if configured as in the present invention, the detecting device for the motor 10 and the pump 21 can be used in common, which has the effect of reducing costs.
