DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In a conventional seeding device, when seeds such as seed paddy that have been invaded by the seeding device and sprouting are transported to a seedling box filled with bed soil, the seed seeds are drained. However, there was a problem that the seeds were not entangled smoothly and the seeds could not be evenly sown because the seeds were entangled with each other and adhered to the seed feeding roll of the seeding device. Therefore, the present invention seeks to eliminate such drawbacks.

[0004]

The present invention has taken the following technical means in order to solve the problems of the prior art. That is, according to the present invention, in the seeding device in which the bed soil supply device B, the watering device C, the seeding device D, and the soil covering device E are sequentially arranged from the transfer start side to the end side of the transfer conveyor 2, the seed padding transfer conveyor 14 is used for germination. The seed draining device of the seeding device is characterized in that the seeds are continuously and sequentially fed while being drained while being fed and supplied to the seeding device D.

[0005]

When the seedling boxes are sequentially transported from the transport start end side to the transport end side by the transport conveyor 2, the seed soil box is filled with the bed soil by the bed soil supply device B, and then the irrigation device C is used. It is irrigated, seeded by the seeding device D in sequence, covered by the soil covering device E, and the seedling box is filled with bed soil and seeded.

In parallel with this, the seed paddy conveyer 14
The seeds invaded and germinated in the plant are transported while being drained by ventilation, and the seeding tank 6 of the seeding device D is transported.
The seeds drained and drained continuously are smoothly fed out from the seeding device D and sown.

[0007]

Embodiments of the present invention shown in the drawings will be described below. First, the overall configuration of the seeding plant will be described with reference to FIG. In this seeding plant 1, the seedling box supply device A, the bed soil supply device B, the irrigation device C, the seeding device D, the soil cover device E, the seedling box automatic stacking device F, from the transfer start side to the end side of the conveyor 2. It is composed of a bed soil supplying device G and the like.

In the bed soil supplying device A, when the stacked seedling boxes 3 are dropped and supplied through the seedling box shoots 4, the seedling boxes 3 are sequentially sent to the carrying start end side of the carrying conveyor 2 one by one. It is a composition. The bed soil supply device B has a configuration in which the bed soil in the bed soil tank 5 is delivered by a bed soil delivery roll (not shown), supplied to the seedling box 3 being conveyed, and packed. The irrigation device C is configured to spray water from the nozzle in a mist state and irrigate the seedling box 3 being transported. The seeding device D has a configuration in which seed paddy in the seeding tank 6 is fed by a feeding roll (not shown) and seeded in the seedling box 3 being transported. The soil cover device E is configured such that the floor soil in the soil cover tank 7 is delivered by a delivery belt (not shown) and is covered with seed rice after seeding of the seedling box 3 being transported. A publicly-known seedling box automatic stacking device F is provided so as to face the terminal end of the conveyor 2, and the seedling boxes 3 in which the bed soil is packed, irrigated, seeded, and covered with soil are sequentially stacked. The structure is such that the devices F are stacked one on top of the other.

A bed soil supplying device G is arranged in parallel on the starting end side of the conveyor 2. This floor soil supply device G
Is the soil hopper 8, belt conveyor 9, elevator 1
0, forward / reverse belt conveyor 1 driven in forward or reverse direction
1 and the floor soil in the floor soil hopper 8 is conveyed to the elevator 10 via the belt conveyor 9, and the floor soil fried by the elevator 10 is forward / reverse belt conveyor 11
Is supplied to the floor soil tank 5 or the soil cover tank 7.

Next, the seed draining device shown in FIGS. 2 to 4 will be described. The draining device for seed paddy is configured as follows. A seed paddy receiving hopper 12 to which seed paddy is supplied, a slanting drainage frame body 13, a draining frame body 13 that is supported by a large number of rollers, and is a seed pad capable of ventilating the seed paddle in an upward slope. .., branch ducts connected to the plurality of suction ports 15, 15, ..., Suction ports 15, 15, .. 16, 16,
The main duct 17 is connected to the main duct 17, and the suction fan 18 is connected to the main duct 17. It should be noted that a pressure air supply port (not shown) may be provided at a position facing upward of the suction ports 15, 15, ... In the seed rice transport conveyor 14 to supply normal temperature air or low temperature hot air.

[0011] When the seed pad infested, disinfected and germinated by the seed pad impregnating device 23 (shown in Fig. 1) is supplied to the seed pad load receiving hopper 12, the seed pad transfer conveyor 13 moves the seed pad to the end side of the transfer. Be transported. During this transportation, suction fan 1

When a suction force is applied to the suction port 15 via the ..., Suction wind flows from the upper side to the lower side of the seed pad of the seed pad conveyer 13 to drain water, and the seed pad is transported to the end side while the water content is gradually reduced and drained. Is continuously supplied to the seeding tank 6 through the seed paddy shoe 19.

In this way, the seed paddy is drained, and 110 kg to 23 seeds of germinated seed pad per hour.
The water is drained at a rate of about 0 kg (equivalent to 800 to 1500 seedling boxes), the seed rice is entangled with each other, and the seed rice is attached to the seed feeding roll (not shown) of the irrigation device C. To prevent the seeds from being sown (11 seeds per box)
Seed about 0 to 150 g. ) Accuracy can be improved. Further, when the seed pad on the seed pad conveyer 14 is drained, suction air is applied from the lower surface side of the transfer surface, so even if a strong wind is applied, there is little turbulence during the transfer of the seed pad and spillage of the seed pad. To prevent draining smoothly. In addition, the net of the seed paddy conveyer 14 is a mesh of 300 mm as a mesh that does not allow seed pad to leak.
If the seed paddy is made about 25 mm thick in a 600 mm x 600 mm and sucked with a suction air of 40 m ³ / min ( 70 aq ),
When the seed paddy conveyor 14 conveys from the suction port 15 on the transport start side to the suction port 15 on the transport end side in about 4 minutes, the water is drained well and the seeding accuracy is improved.

Next, another embodiment of the draining device will be described with reference to FIGS. The drainer of this seed paddy is configured as follows. Seed-padded cargo receiving hopper 12 to which germinated seed-padded rice is supplied, seed-paddy feeding conveyor 24 that conveys seed paddy from seed-padded cargo receiving hopper 12, draining case 2
0, the seed paddy inlet 21 provided on the upper part of the drainage case 20, and the upper half of the drainage case 20,
Seed pad conveyer 14, 14, ..., which is composed of a net that takes over the seed pad received from the seed pad tray 21 and sequentially conveys the seed pad downward, receives the seed pad transported by the seed pad conveyer 14 at the lowermost stage. Supply hopper 2
2, Suction port 1 opened at the top of the drainage case 20
5, 15, ..., Consists of suction fans 18 arranged below the draining case 20.

When the seed pad infested, disinfected and germinated by the seed pad impregnating device 23 (shown in FIG. 1) is supplied to the seed pad receiving port 21, the seed pad transfer conveyor 14 in the upper stage transfers the seed pad in the middle stage. While the conveyor 14 and the lower-step rice seed transporting conveyor 14 are being transferred and transferred while being folded back, while the suction air flows from the upper suction port 15 to the suction fan 18, the seed rice is drained, and the seed rice after draining is supplied to the hopper. It is supplied to the seeding tank 6 from 22 and has the same effect as the above-mentioned embodiment.

[0015]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, seeds that have invaded and germinated are continuously drained to the seeding tank 6 of the seeding device D by being drained by ventilation while being transported by the seed paddy conveyor 14.
