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 pots have become popular.

Paper pot paper L is 1 horizontally as shown in Figure 1.
About 6 bots 2 are arranged in parallel, and about 17 bots 2 are arranged in parallel in the vertical direction. Conventionally, 3 bots were sown on each bot 2 by hand.
Seeds were sown one by one, but since hand sowing is difficult, sowing was done by machine.

In the present invention, when mechanically sowing the paper pot paper, the paper pot paper itself is made of paper and is not flat, and the fit in the storage case that houses it is also uncertain, so before starting a series of sowing operations, suppressed from above
? The paper pot paper is almost securely stored in the storage case by pressing down on the paper pot, and then a series of seeding operations are performed.

Fig. 1 shows a state in which the paper pot paper 1 is being stored on one side of the storage case 3, and Fig. 2 shows the same storage state, but normally the paper pot paper 1 is stored in the storage case 3.
Two pieces are placed side by side. Storage case 3 like this
When the paper pot paper l is placed inside, the lower end 4 of the bot 2 rises above the bottom of the storage case 3 and is stored, as shown in FIG. This is because the paper bot paper 1 itself is very light and the lower end portion 4 is formed with unevenness. If the covering soil 5 is thrown in from above in this state, the covering soil 5 will leak from the through hole 6 formed in the lower end portion 4 as shown in FIG. 3, so this should be avoided.

The storage case 3 has a drawer shape and is sized to fit two approximately square paper pot papers 1 side by side. form. The paper pot paper 1 is made of a water-soluble paper material. Each bot 2 is formed into a substantially regular square shape when viewed from above, and becomes narrower toward the lower end 4 when viewed from the side. A through hole 6 is provided in the lower end 4 of the bot 2.
form. The sprouts 8 of the seeds 7 sown in the bot 2 extend upward from the through holes 6. That is, the paper pot paper 1 is covered with +5 in the pot 2 while being fitted in the storage case 3, which three seeds 7 are sown on the covered soil 5, and the bed +9 is placed on top of it. (Fig. 5), cover the seedling raising box 10 from above (Fig. 6), turn it upside down, remove the upper storage case 3, and insert the eyes ±11 into the gaps of each bot 2 (see Fig. 6).

appears upwards.

FIG. 9 shows an apparatus for dispensing m types of seeds 7, 3 seeds each, into each of the 34 bots 2 lined up in total as described above, and when configured as shown in FIG. ,3
Grain sowing is possible.

That is, the paper bot l moves at a constant speed in the direction of arrow A. The speed depends on the horizontal transfer stage of the conveyor. 12 is a feeding device for seeds 7, and the feeding device 12 feeds out seeds 7 continuously, but while the paper pot paper 1 passes, 102 seeds are fed out according to the arithmetic calculation of 34×3=102 seeds. This feeding will be described in detail later, but if a spiral roll is used, it can be done by simply determining the number of revolutions. Then, as shown in Figure 9, the 102 grains will be distributed to each of the 34 bots 2. Since the size and speed of each bot 2 are constant, approximately 80% will be sowing 3 grains, and 10% will be sowing 3 grains. Sow 2 seeds, 10% is 4
This is grain sowing.

A substantially central portion of the push rod 57 is bent upward to form a bent portion 63, and a pressure roll 64 is provided below the bent portion 63. The mounting structure of the pressing roll 64 is the same as that of the pressing roll 19.

On the downstream side of the motor 56, a bed soil supply device 65 is formed by a hopper 66, a delivery belt 67, a bed soil supply amount adjustment device 68, and the like. A pressure roll 69 is provided on the downstream side of the bed soil supply device 65.

The pressing roll 69 is for pressing the bed ±9 supplied by the bed soil supply device 65.

The push rod 57 and the pressing roll 64 are used to prevent the rear end of the storage case 3 from floating when the paper pot paper 1 is pressed by the pressing roll 69.
The front end 70 of the push rod 57 is formed to protrude below the feed belt 67 of the soil supply device 65 just before the soil falls, and the pressure rolls 64 and 69 are shorter than the length in the longitudinal direction of the storage case 3. Provide them at intervals. Suppression roll 6
A scraper 71 is provided on the lower side of 9. It was suppressed using a suppression roll 69.

This is for scraping off the excess soil on the top of pot 2 later.

72 is a passive shaft, 73.75 is a gear, 74.76 is a pulley,
77 is a belt, and 78 is a drive shaft.Next, the operation will be described.

When the storage case 3 fitted with paper pot paper l is placed on the starting end side 14 of the horizontal transfer table 13, the storage case 3 is transferred toward the terminal end side 15 by the guide roll 16 and the guide belt 17, and guided downward. Since the suppression 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.
To prevent a cover 5 from leaking from a through hole 6 of a pot 2.

Since there is a covering soil supply device 27 immediately below the pressing roll 19, the paperboard/h paper l is pressed into the storage case 3 and the covering material 5 is not leaked from the through hole 6 of the pot 2 until the covering soil supply device is placed. 27, the covering soil 5 is supplied into the pot 2 of the paper pot paper 1 by the device 27, and the device further advances to reach the bottom of the seed rice feeding device 12.

The spiral grooves 36 and peaks 37 of the spiral rolls 34 arranged in parallel in the seed rice feeding device 12 rotate in a state in which the left and right sides coincide with each other. A fitting groove 38 is formed at the bottom of the moving groove 39 where the spiral groove 36 and the spiral groove 36 meet.
is formed, so when the spiral roll 34 rotates,
The fitting groove 38 of the seed transfer groove 39 is aligned with the terminal end 3
Proceed in the direction of 5.

Therefore, a suction case 42 is provided below the spiral roll 34 and sucks air from 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 into the respective fitting grooves 38. From the terminal end 35 of the seed transfer groove 39, the seeds are guided to the drop chute 45 and fall into the pot 2 into the M-direction.

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 will fall into the pot 2 at a time.

In this sowing, the seeding device 32 initially supplies seeds 7 into the pots 2 at odd-numbered locations in the left-right direction of the paper pot paper l, and the seeding device 32 does not supply seeds 7 into the pots 2 at even-numbered locations in the left-right direction. . When the storage case 3 moves below the seeding device 33, the seeds 7 are placed in the pots 2 at even-numbered locations.
will be supplied.

When the sown paper pot paper l is directed below the pusher 57 by the guide roll 16 and belt 17,
It is guided below the press roll 64 while being pressed by the push rod 57 . Like the press roll 19, the tip of the rotating arm 22 of the press roll 64 is urged to rotate downward by the spring 25, so it presses the paper pot paper 1 and also presses the front end 70 of the push rod 57. is formed so as to protrude from the feeding belt 67 of the above-floor feeding device 165 to a point below just before the floor ±9 falls, and the pressing roll 64 and the pressing roll 69 are provided at an interval shorter than the length in the longitudinal direction of the storage case 3. Therefore, when the floor ±9 supplied into the pot 2 is pressed by the pressing roll 69, the lower end of the storage case 3 does not rise.

Since a scraper 71 is provided on the downstream side of the pressure roll 69, after the pressure is suppressed by the pressure roll 69, the excess on the floor is scraped off and ms is completed.

The present invention has been described above, and in particular, the paper pot paper l is fitted into the drawer-shaped storage case 3 from above, and the paper pot paper l is placed on the horizontal transfer table 13 of the conveyor-type seeding device and moved. In the device for sowing seeds on paper 1, the sowing S device is provided with at least a covering soil supply device 27 or a floor feeding device 65, and a paper pot paper l is provided on the upper side of the soil covering feeding device 27 or the floor feeding device 65.
This is because the seeding device is provided with a pressing device that presses the paper pot paper l into the storage case 3, and supplies the covering soil 5 or the bed ±9 after pressing the paper pot paper l with the suppressing device.

B. The spiral roll 34 uses its spiral groove 36 to move the seeds one by one to the terminal end 35 and drop the seeds one by one, so that the seeds can be easily and easily placed in each pot of paper pot.
You can make as many points as you like.

In the above case, the four sections can be rotated at a constant ratio to the rotational speed of the spiral roll 34, so that a desired number of seeds can be dropped.

C. By synchronizing the rotation speed of the rotating roll 34 and the transport speed of the storage case 3, it is possible to accurately seed the paper pot paper 1 into each pot 2.

2. Eliminates the need for thinning work after sowing in the field.

This effect is achieved.
