Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a seeding device for port sheets that accurately feeds seeds one by one into small depressions formed at the top of a pot. .

(Prior Art) Conventionally, as shown in FIG. 1, a cardboard pot sheet B on which a number of boats A are arranged in rows and columns is placed on a mounting plate C.
Each Boer) Put cover ± D into A, sow seeds E on top of the cover soil, then put bed soil F, cover with seedling box G from above,
It is well known to invert the seedlings, remove the mounting plate C, and grow them into potted seedlings H.

Also, in Japanese Patent Application Laid-open No. 63-237708 (Figure 2),
A pot A is placed on a bell hI, and a hoe 2 bar with a supply port formed at the bottom is provided on the top of the pot A, and a discharge port K is formed with a vertical gap below the supply port. A seeding device J is described which is provided with a shutter having a communication port M between the seeding device J and the discharge port to communicate with each other.

(Problem M to be solved by the invention) In Fig. 1, the seeds E are limited to paddy, and 2.
Since it is a technique of sowing 3 seeds, lettuce etc. to be planted in a grove requires 2 seeds.
．． If you sow 3 seeds, you will have to thin them out, which is very time consuming and impossible to carry out. Only one potted seedling, such as lettuce, etc.
It is required to sow only the grains accurately.

The device disclosed in JP-A No. 63-237708 has a discharge port K formed with a vertical gap below the supply port of the hopper, and a communication port that communicates between the supply port and the discharge port. M is provided, but the coated seeds of vegetables are very small, and the supply opening etc. is formed to a size that allows seeds to fit one by one.
When there is even a small amount of moisture in the supply port, etc., or if the supply port is charged with static electricity, a seed may stick to the inner wall of the supply port and not fall.
This can cause stock shortages.

(Objective of the Invention) Therefore, the present invention prevents the occurrence of missing plants by ensuring that the seeds fitted into the supply port, the discharge port, and the communication port fall.

(Means for Solving the Problems) Therefore, the present invention moves the pot sheet 1 at a constant speed by a transfer device, and the small depressions 10 formed at the top of each pot 2 of the moving pot sheet 1 are Seed 1
1, the seeding device 2 is formed to repeatedly move at the same speed as the pot 2, and the seeding device 1 is provided with a hopper n having a circular divided supply port 15 formed at the bottom thereof. , a discharge port 16 is formed below the supply port 15 with a vertical gap, a shutter 17 having a communication port 18 is provided between the supply port 15 and the discharge port 16 to communicate with each other; , communication port 18
This seeding device for pot sheets is provided with a microvibration device 24 that slightly vibrates each of the discharge ports 16.

(Example) An embodiment of the present invention will be described with reference to the drawings.

1 is a pot sheet made of paper material.

The bottom parts 3 of a large number of pots 2 for the stock are connected vertically and horizontally through connecting parts 4 to form a square shape.

5 is the upper wall of the pot 2, and the side surface shape of the pot 2 as a whole is a pyramid or a cone. 6 is a through hole formed in the center of the upper wall 5.

The pot sheet 1 is placed on a mounting plate 8 on which a large number of projections 7 are formed, as shown in FIG. Then, a large number of protrusions 7 protrude into each pot 2 from the through hole 6. When the sieve ±9 is filled from above in this state, many protrusions 7 protrude into the pot 2, so as shown in Figs. 3 and 6,
A small depression 10 is formed inside the through hole 6.

The seeds 11 are reliably sown one by one in the small depression 10, and the device used is as shown in FIG.
2 is configured to repeatedly move in the moving direction of the pot sheet 1 at the same speed.

The pot sheet 1 with the small depression 10 formed inside the through hole 6 of the upper wall 5 is placed on the seedling growing box 13 as shown in FIG.
It is moved at a constant speed in the direction of arrow A by a transport device (not shown). Seeds 11 are fed one by one into small depressions 10 formed at the top of each pot 2 of this moving pot sheet 1, and the drop opening 14 at the bottom
repeatedly moves immediately above the upper wall 5 of the pot 2 toward the mouth at the same speed as the pot seat 1 moves.

η is the entire case of the seeding device l, with a hopper 23 at the top.
A circular divided supply port 15 is formed at the bottom of the Hocher, and a discharge port 16 is formed with a vertical gap below the supply port 15.
A shutter 1 is formed between the supply port 15 and the discharge port 16.
Install 7.

18 is a communication port formed in the shutter 17, which is connected to the supply port 15.
When the communication ports 18 match, one seed 11 fits into each communication port 18, and when the communication ports 18 match the discharge ports 16, the seeds 11 are dropped from the drop port 14 moving through the hose 19.

The red is any drive device that repeatedly moves the seeding device 12 as a whole as shown by the arrow (b), and may use a crank, a link mechanism, or any other well-known mechanism. .

Except for the special pot sheet l, the pot 2 is usually
Since they are formed in 10 rows horizontally and 24 rows vertically, in the embodiment, four drop ports 14 are formed in the moving direction so that seeds 11 can be sown in four rows of pots 2 at one time. 6
The sowing in one seedling raising box 13 is completed by repeating the process twice.

Since the seeding device N12 moves as described above, the shutter 17 is structured so that when the seeding device 12 moves in the direction A, the shutter 17 moves to coincide with the discharge port 16. Alternatively, a separate opening/closing drive mechanism 21 may be provided to open and close the opening/closing mechanism.

Thus, the seeds 11 in the hopper 23 fit into the supply ports 15, and when the supply ports 15 and communication ports 18 match, they fall into each communication port 18, and when the communication ports 18 match the discharge ports 16, they fall into the respective communication ports 18. It falls into the hose 19. However, the coated vegetable seeds 11 are very small, and the supply ports 15 and the like are formed in a size that allows each seed 11 to fit therein one by one. If the supply port 15 or the like is charged with static electricity, the seeds 11 may adhere to the inner wall of the supply port 15 or the like and not fall.

According to the present invention, each of the supply port 15, the communication port 18, and the discharge port 16 is integrally attached to the case rod, the hopper B is provided with a micro-vibration device 24, and the supply port 15, the communication port 18, and the discharge port 16 are The structure is such that the seeds 11 fitted into each of the holes fall smoothly.

The micro-vibrating device 24 prevents the seeds 11 from adhering by having a structure in which the supply port 15, communication port 18, and discharge port 16 are constantly vibrated slightly, or are vibrated by applying impact at predetermined intervals.

The micro-vibration device 24 may be configured to use a motor to generate micro-vibration, or may utilize repetitive movement of the entire seeding device.

(effect) Next, we will discuss the effect.

When the pot sheet 1 is placed with the top wall 5 facing down on the top of a mounting plate 8 having a large number of protrusions 7, the tips of the protrusions 7 of the mounting plate 8 will protrude into the pot 2 from the through holes 6. .

In this state, put a sieve ±9 from above, press it from above so that it will not collapse even if it is turned over, and place the seedling raising box 13 upside down.
If you cover the seedling box 13 from above and turn it over, the mounting plate 8
is on top. When the upper mounting plate 8 is removed, a pot 2 with a small depression 10 formed inside the upper wall 5 is obtained.

When this pot sheet 1 is supplied together with the seedling growing box 13 to the transfer table, the pot sheet 1 is moved by the transfer table at a constant speed in the A direction and reaches the lower part of the seeding device l. and the sixth
As shown in the figure, since the seeding device 12 is repeatedly moved in the direction of the seedling by the driving device, the seeding device and the seedling raising box 13 are moved in the direction A at the same speed. Each drop opening 14 at the lower end moves while being aligned with each small depression 10.

Therefore, when the opening/closing mechanism 21 is operated to align the communication port 18 of the shutter 17 with the discharge port 16, one seed 11
is hose 19. It is supplied through the drop opening 14 so as to hit each small depression 10.

The seedling raising box 13 continues to be moved in the A direction, but the seeding device 12 is moved entirely in the opposite A direction by the driving device 4, and then the seedling raising box 13 is moved in the A direction repeatedly. The seedling raising box 13 and the seeding device l12 both move in the A direction at the same speed again, and perform the same seeding work as before.

If this is usually repeated six times, the number of vertical boats in one seedling raising box 13 is usually 24, so seeds can be sown in all of them.

In the above case, the seeds 11 in the hopper n fit into the supply port 15, and when the supply port 15 and the communication port 18 match, they fall and fit into each communication port 18, and the communication port 18 matches the discharge port 16. Then, the seeds 11 fall into the hose 19, but the seeds 11 may not fall from each of the supply port 15, the communication port 18, and the discharge port 16.

In the present invention, the supply port 15, the communication port 18, and the discharge port 16 are each integrally attached to the case member, and the hopper 23 is provided with the micro-vibration device 24.
The seeds 11 fitted into the and discharge ports 16 are connected to the supply ports 1
5. It falls smoothly without adhering to the inner walls of the communication port 18 and the discharge port 16.

(Effects) The present invention moves the pot sheet (1) at a constant speed using a transfer device, and the seeds 11
The seeding device 12 is formed to repeatedly move at the same speed as the pot 2, and the seeding device 12 is provided with a hopper n with a circular divided supply port 15 formed at the bottom. , a discharge port 16 is formed with a vertical gap below the supply port δ, a shutter 17 having a communication port 18 is provided between the supply port 15 and the discharge port 16 for communicating these; , communication port 18
and a pot sheet sowing device equipped with a micro-vibration device 24 that slightly vibrates each of the discharge ports 16! Since it is a device, the seeds 11 fitted into the supply port 15, the communication port 18, and the discharge port 16 are
It is possible to reliably fall without adhering to the inner walls of each, thereby preventing the occurrence of missing plants.
