The seedling boxes conveyed by the conveyors 4 and 7 are first conveyed to the floor soil filling device 5 and supplied with the floor soil. Next, it is transported to the seeding device and seeded, and then covered with the soil covering device 9. And at the time of emergency stop, driving of the seeding device 8 is stopped, and driving of the conveyors 4 and 7 is stopped after a predetermined time. At the time of restarting, the seeding device 8 starts to be driven, and the driving of the conveyors 4 and 7 is resumed after a predetermined time has elapsed .
[0005]
【The invention's effect】
Therefore, according to the present invention, it is possible to prevent the seeding apparatus from being disturbed by the seeding device that can have an extremely large number and a small number as shown in FIG. 6 (b) by an emergency stop or restart. .
[0006]
【Example】
An embodiment of the present invention will be described below with reference to the drawings.
1 to 4, 1 is a seedling box stock conveyor, 2 is a seedling box insertion device, 3 is a seedling box supply device, 4 is a soil filling / watering conveyor, 5 is a floor soiling device, and 6 is watering The device 7 is a sowing / covering conveyor, 8 is a seeding device, 9 is a soil covering device, and 10 is a fast-forwarding conveyor. The seedling box inherited from the sowing / covering conveyor 7 is forwarded faster than the conveyor 7.
[0007]
Reference numeral 11 denotes a lift conveyor which receives the seedling box sent by the fast-feed conveyor 10 on the receiving plate 12 and lifts it up to a predetermined height position. Then, the seedling box lifted up to the predetermined height position is drawn out onto the transport conveyor 14 by the seedling box drawing device 13 and is transported from the transport conveyor 14 to the stacking device 16 via the stacking conveyor 15. This is a configuration.
[0008]
M is a motor for driving the lift conveyor 11. SW is a detection switch for detecting that the seedling box has been sent by the fast-feed conveyor 10 and has just reached the receiving state where the lift conveyor 11 is lifted. This detection switch SW The motor M is driven to rotate on the basis of the detection result.
The lift conveyor 11 has a narrow interval pitch between the upper receiving plate 12 and the lower receiving plate 12 so that each of the seedling boxes K is lifted up as close as possible, and accepts the seedling box. The standby posture of the receiving plate 12 at the position is configured to be inclined obliquely downward from the upper surface of the fast-feed conveyor 10. That is, the tilt angle θ is held obliquely downward with respect to the horizontal line passing through the axis Q of the lower ring body 11b around which the lift conveyor chain 11a is wound. This state is the receiving plate 12 at the seedling box receiving position. It becomes the waiting posture.
[0009]
The seedling boxes supplied to the soil filling / irrigation conveyor 4 by the seedling box supply device 3 are sequentially conveyed one by one and sent to the floor soiling device 5 where the floor soil is supplied. Next, after irrigating the floor soil by the irrigation device 6, seeds are sown by the sowing device 8 and covered by the soil covering device 9 from above. Then, the seedling box after sowing is inherited from the sowing / covering conveyor 7 to the fast-forwarding conveyor 10 and then fed forward.
[0010]
When the seedling box conveyed by the fast-feed conveyor 10 reaches the seedling box receiving position of the rear lift conveyor 11, the detection switch SW is turned on to detect the receiving state of the seedling box on the receiving plate 12, and based on this detection result The motor M is driven to rotate. Accordingly, the lift conveyor 11 is received and held by the receiving plate 12 by the ascending rotation of the conveyor 11, lifts the seedling box up to a predetermined position, and then immediately stops.
[0011]
Next, when the succeeding seedling box reaches the position in front of the lift conveyor 11, a detection switch (not shown) is turned on to detect it. In this case, that is, the preceding seedling box has already been lifted up. The succeeding seedling box is sent as it is to the position where it reaches the detection switch SW.
The seedling box lifted up to a predetermined height position is drawn out by the seedling box drawing device 13 and is transferred to the stacking device 16 via the transfer conveyor 14 and the stacking conveyor 15.
[0012]
As described above, the seedling box lift device receives on the receiving plate 12 the fast-feed conveyor 10 that inherits the seedling box sent from the seeder and fast-forwards backward, and the seedling box that is conveyed by the fast-feed conveyor 10. A lift conveyor 11 for lifting is provided, and the lift conveyor 11 is configured to stand by in a state where the receiving plate 12 at the seedling box receiving position is inclined obliquely downward from the upper surface of the fast-feed conveyor 10.
[0013]
Therefore, the seedling box is transported to the rear lift conveyor 11 by the fast-forwarding conveyor 10 and reaches the seedling box receiving position on the receiving plate 12 that is waiting obliquely downward from the upper surface of the fast-forwarding conveyor 10. When the detection switch SW in the seedling box receiving position detects the seedling box receiving state, the motor M is driven to rotate by the detection result, and the receiving plate 12 that moves upward as the lift conveyor 11 moves upward. The seedling box is engaged and held and lifted up to a predetermined position.
[0014]
Therefore, the mounting pitch of the receiving plate 12 with respect to the lift conveyor 11 can be made as narrow as possible, and the seedling box that enters is the upper seedling box while the pitch between the receiving plate 12 and the receiving plate 12 is narrow. It is possible to lift up smoothly and satisfactorily without hitting the receiving plate 12.
[0015]
Conventionally, as disclosed in, for example, Japanese Patent Application Laid-Open No. Sho 62-221, a seedling box inherited from a seeder-side conveyor to a lift conveyor is received on a receiving plate to a predetermined height position. In the lifting device, when the seedling box transported by the transfer conveyor reaches the proper receiving position on the lifting conveyor receiving plate, this is detected by the detection device and the lift conveyor is driven to place the seedling box in a predetermined position. To lift up. In such a conventional type, since the mounting pitch of each seedling box receiving plate is made rough, when the seedling box lifted to a predetermined height position is pulled out to the stacking apparatus side, for example, when pulling out two or more boxes, the upper box Due to the shock that occurs when the water drops on the lower box, the soil tends to be displaced in the seedling box. Therefore, it is necessary to make the pitch of each receiving plate as narrow as possible, but if this is made too narrow, the seedling box entering on the transfer conveyor (fast-forwarding conveyor) will easily hit the upper seedling box receiving plate, and there is a limit. there were.

13 to 19 will be described.
When using a tray P that does not fit the paddy rice seedling box K1 as shown in FIG. 13, conventionally, the tray P is positioned and fixed to the paddy rice seedling box K1 via a tray guide 21 'as shown in FIG. 14 and FIG. I was trying to do it. However, even when the floor soil upper surface on the tray P is leveled by the action of the leveling brush 22, the tray guide 21 'and the rice seedling box K1 lower than the tray upper surface in FIG. 14 and the tray guide in FIG. There was a problem that floor soil remained on the upper surface of 21 '.
[0023]
Therefore, in the embodiment shown in FIGS. 16 and 17, the tray guide 21 that coincides with the upper surface of the tray P is provided. As a result, the above-mentioned problems as in the prior art can be solved.
[0024]
In particular, in the embodiment shown in FIG. 17, the guide width L1 of the front tray guide 21 is significantly larger than the rear guide width L2 with respect to the seedling box transfer direction (the traveling direction during sowing).
The reason is that when seeding with a vacuum seeder, the reverse of the above, that is, as shown in FIG. 18, the guide width of the front tray guide is made smaller than that of the rear side with respect to the seedling box traveling direction. When the last sowing of the tray in the rearward direction of the tray is performed, the sowing hole formed body 23 comes into contact with the wide width tray guide 21, so that the sowing nozzle 24 that moves up and down together with the sowing nozzle 24 also moves the top surface of the tray. There was a problem that the seeds jumped out by dropping the seeds from the higher place. Therefore, with the above configuration, as shown in FIG. 19, the seeding nozzle 24 is in the state of entering the sowing hole H portion even at the time of the last sowing, and the problem of seed popping out is solved.
