Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seeding device for paper pot paper.

Conventionally, seedlings grown in soil for rice transplanters have progressed from seedlings sown in soil to seedlings in soil sown in rows, and recently, seedlings in soil in paper pots using paper pot paper have become popular.

The paper pot paper is 16 mm horizontally as shown in Figure 1.
About 17 pots are placed side by side in the vertical direction. Conventionally, three seeds were sown in each pot by hand, but it is difficult to sow by hand. It is mechanically sown.

In the present invention, when mechanically sowing the paper pot paper, since the paper pot paper itself is made of paper and is not flat, and it is not sure how well it fits in the storage case that houses it, the paper pot paper is pressed from above with a suppressing device. The paper pot paper is stored almost securely in the storage case, and the seeding work is performed in this state.

FIG. 1 shows a state in which paper pot paper l is being stored on one side of the storage case 3, and FIG. 2 shows the same storage state. Usually, two sheets of paper pot paper 1 are stored side by side in a storage case 3. When the paper pot paper 1 is fitted into the storage case 3 in this way, the lower end 4 of the pot 2 is stored slightly raised above the bottom of the storage case 3, as shown in FIG. This is because the paper bot paper l itself is very light and the lower end portion 4 is formed with unevenness. In this state, if the covering soil 5 or flooring ±9 is poured from above, the covering soil 5 will leak into the bot 2 through the through hole 6 formed in the lower end 4, resulting in a situation as shown in Fig. 3, so avoid this. .

The storage case 3 has a drawer shape and is formed in a size that allows two approximately square paper pot papers L to be fitted side by side, and on the top surface of the bottom plate there is a groove to prevent each pot paper L from moving in the front and back direction. Forms ridges. Paper pot paper l is formed from water-soluble paper material. Each bot 2 has a substantially regular square shape when viewed from above, and has a lower end 4 when viewed from the side.
It becomes narrower as it reaches. The sprouts 8 of the seeds 7 sown in the pot 2 extend upward from the through hole 6. That is,
The paper pot paper l is fitted into the storage case 3 and supplies the cover soil 5 into the pot 2, sows three seeds 7 on top of the cover soil 5, and supplies the bed ±9 on top of it. (Fig. 5), cover the seedling raising box 10 from above (Fig. 6), turn it over, remove the storage case 3, and place the seeds 11 in the gap between each pot 2.
(Fig. 7), and after growing for a certain period of time, a bud 8 will emerge upward from the through hole 6 as shown in Fig. 8.

FIG. 9 shows a device for sowing three seeds 7 into each of the 34 bots 2 lined up as described above, and when configured as shown in FIG. 9, the pot paper l is moved intermittently. Three seeds can be sown at a rate of approximately 80% without this.

That is, the paper bot l continuously moves in the direction of arrow A at a constant speed. The speed depends on the horizontal transfer stage of the conveyor. Reference numeral 12 denotes a device for dispensing seeds 7, and the dispensing device 12 continuously dispenses seeds 7. While the pot paper I passes through, 102 seeds are dispensed based on the arithmetic calculation of 34×3=102 grains. Adjust accordingly. This feeding will be described in detail later, but if a spiral roll is used, it can be easily carried out by simply determining the number of revolutions. Therefore,
As shown in Figure 9, 102 seeds will be distributed to each of the 34 bots 2, and since the size and speed of each pot 2 are constant, approximately 80% will sow 3 seeds, and 10% will sow 2 seeds. sow,
10% of the crops are sown with 4 seeds.

When the storage case 3 fitted with the pot paper l is placed on the starting end side 14 of the horizontal transfer table 13, a guide roll 16 and a guide bell) 1
7, the storage case 3 is transported at a constant speed toward the terminal end 15 and guided below the pressure roll 19. Since the pressing roll 19 is urged to rotate downward by the spring 25, it presses the paper pot paper l so that the lower end 4 of the pot 2 comes into close contact with the upper surface of the bottom plate of the storage case 3, and the pot 2 Prevent the covering soil 5 from leaking through the through hole 6.

Since there is a covering soil supply device 27 on the lower side of the suppression roll 19, the pot paper l is pressed into the storage case 3 and the covering soil 5 is supplied below the soil covering supply device 27 through the through hole 6 of the pot 2 without leaking. The covering soil 5 is supplied into the pot z of the pot paper l by the device 27, and the device 27 advances further to reach the bottom of the seed rice feeding device 12.

The mutual spiral grooves 36 and spiral crests 37 of the parallel spiral rolls 34 of the seed rice feeder 12 rotate in a state in which the left and right sides coincide with each other.
Seed moving grooves 39 are formed respectively, and a spiral groove 36 and a fitting groove 38 are formed at the bottom of the moving groove 39 by combining the two spiral grooves 36, so when the spiral roll 34 rotates, the seed moving groove 39 is formed. The fitting grooves 38 of 39 advance in the direction of the terminal end 35 at a constant speed in a matched state.

Therefore, a suction case 42 is provided below the spiral roll 34 and sucks air through the suction port 44 of the device, so that the suction air blows from top to bottom through the fitting groove 38 and moves through the seed transfer groove 39. Since the seeds 7 are sucked downward, the seeds 7 move through the seed moving grooves 39 to the terminal end 35 without coming off while being fitted one by one in each fitting groove 38. From the terminal end 35 of the seed moving groove 39, the seeds are guided by a falling chute 45 and fall continuously into the pot 2.

Therefore, if the transfer speed of the storage case 3 and the rotation of the spiral roll 34 are designed to be synchronized and rotated, three seeds 7 each will be transferred to the pot 2 without intermittent movement of the storage case 3.
It will fall inside.

In this sowing, the seeding device 32 first supplies the seeds 7 into the pots 2 at odd-numbered locations in the left-right direction of the pot paper 1, and then the seeds 7 are supplied into the pots 2 at even-numbered locations in the left-right direction by the sowing device 32.
not supplied. Then, as the storage case 3 moves below the seeding device 33, the seeds 7 are supplied into the pots 2 at even-numbered locations.

As with the press roll 19, the tip of the rotating arm 22 of the press roll 66 is urged to rotate downward by the spring 25, so the press roll 66 presses the pot paper l, and the paper pot paper l is pressed. The bottom end 4 of the pot 2 is brought into close contact with the top surface of the bottom plate of the storage case 3, and the soil covering 5 is inserted through the through hole 6 of the pot 2.
Does not leak. At this time, the press roll 66 is provided below the bent portion 61 of the push rod 57, and the push rod 57 is connected to the protruding rod 59.
Since the spring 65 is wound around the roller 62 and the push rod 57 presses the pot paper 1 downward, the pressure roll 66 pushes the pot paper 1 downward.
Even when pressed, neither the front end nor the rear end of the pot paper I is lifted up, and the pot paper I moves forward.

When the advanced potting paper l runs below the bed soil supply device 67, it is supplied with the floor ±9, but the pressure roll 66 and the pressure roll 71 are provided at an interval shorter than the length in the longitudinal direction of the storage case 3. Since the front end @472 of the push rod 57 is formed to protrude below the feed belt 67 of the bed soil supply device 67 just before the floor ±9 falls, the pressing roll 71
The lower end of the storage case 3 does not lift up when the floor ±9 supplied into the pot 2 is compressed.

Since a scraper 73 is provided on the downstream side of the pressing roll 71, after the seedlings are crushed by the pressing roll 71, the excess on the bed is scraped off and sowing is completed.

The present invention has been described above, and in particular, the paper pot paper 1 is fitted into the drawer-shaped storage case 3 from above, and the paper pot paper 1 is placed on the horizontal transfer table 13 of a conveyor-type seeding device and moved. In the device for sowing seeds in the soil, the seeding device is provided with a covering soil supply device 27 and/or a bed soil supply device 65, and the pot paper L is placed near the soil covering device 27 and/or the bed soil supply device 65. A push rod 57 for elastically pressing is provided in the storage case 3, and the push rod 57 is long in the direction of movement of the pot paper l. Since the seeding device is designed to feed Hehapot paper 1, it can almost certainly be stored in the storage case 3, and seeding operations such as supplying the covering soil 5 and bed soil 9 can be carried out in this state. Supply of ±9 is ensured.
