Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pot sheet seeding device that accurately feeds seeds one by one into small depressions formed in the upper part of a pot.

(Prior art) Conventionally, as shown in Fig. 1, a cardboard pot sheet B on which a large number of pots A are arranged in rows and columns is placed on a mounting plate C, and each pot A is covered with soil. , sow seeds E on top of the soil,
Next, a method is known in which bed soil F is put in, a seedling raising box G is placed on top, the seedling raising box G is turned over, the mounting plate C is removed, and the seedlings are grown into potted seedlings H.

Also, in Japanese Patent Application Laid-open No. 63-237708 (Figure 2),
A device is described in which a pot A is placed on a belt I and a seeding device J is provided above the pot A.

(Problem to be solved by the invention) In the case of Fig. 1, the seeds E are limited to paddy, and the seeds E = 2 on D.
．． The technique involves sowing three seeds, and cannot be applied to potted lettuce, cabbage, or Chinese cabbage seedlings. That is, since lettuce and the like are meant to stand alone, if 2 or 3 seeds are sown, they must be thinned out, which is very time-consuming and impracticable. For potted seedlings such as lettuce, it is required that only one seed be sown precisely in the center. In the case of Fig. 1, it does not matter if the position of the seeds E is sown on the cover soil as shown in Fig. Therefore, it is used as seedlings for rice planting by sowing 2.3 seeds.

As mentioned above, in the case of lettuce seedlings, a small depression is previously formed in the center of the second part of the pot, and only one coated seed is sown there.

The one disclosed in Japanese Unexamined Patent Publication No. 63-237708 is Bell 1.
Place a point on the 4J2, and place a seeding device on a part of it.
However, the defect of the known example is that the seeding device J
itself is formed into an immovable structure, and in particular, since the lowermost droplet K is immovable, the seeds E that have fallen through the lowermost droplet of the immovable structure will fall into the small center of the moving pot A. This is a configuration in which the object is dropped into a depression, and with this configuration, it may be out of position and not fall into the small depression in the center.

In addition, many cardboard pot sheets are distorted, and the distorted portion of a distorted cardboard pot sheet protrudes upward, so the pot sheet 1 at the bottom of the immovable structure has a large number of protrusions 7. It is placed on top of the formed storage board 8 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 the top in this state, many protrusions 7 protrude into the pot 2.
As shown in FIGS. 3 and 6, there is a small depression 10 inside the through hole 6.
is formed.

The seeds 11 are reliably sown one by one in the small depression 10, and the device used is as shown in FIG. This is a circular motion that moves at the same speed as pot 2.

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 laterally at a constant speed in the direction of arrow A by a transport device (not shown).

Seeds 11 are supplied one by one to the small depressions 10 formed in the -1 part of each pot 2 of this moving pot sheet 1. The opening 14 may be caught on the lower opening K of the horizontal axis rotation.

(Means for Solving the Problems) Therefore, the present invention causes the pot sheet 1 to be moved laterally at a constant speed by a transfer device, and the pot sheet 1 that is being moved laterally is
In the pot sheet seeding device that supplies seeds 11 to small depressions 10 formed at the top of each pot 2, the drop opening 14 at the bottom of the seeding device is perpendicular to the moving direction of the pot sheet 1. This is a pot sheet seeding device that uses a crank on the horizontal axis to create a circular motion that moves at the same speed as the pot 2 when approaching the pot.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. 1 is a pot sheet made of paper material, and a large number of pots 2 for each plant are used.
The bottom portions 3 of are connected vertically and horizontally by connecting portions 4 to form a rectangular shape.

5 is the upper wall of the pot 2, and the side 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 wall 5.

It is configured to move in a vertical circle as shown by the arrow (b) depending on the rank (Fig. 7). Also, the drop port 14 rotates once,
When approaching the upper wall 5 of the pot 2, the pot 2 is pressed from above as shown by the thick line at the trajectory opening, and the pot 2 is configured to move together with the pot 2 at the same speed.

When the pot 2 is pressed from the bottom, the distorted pot sheet 1 is flattened and the pot sheet 1 is brought into close contact with the small depression 10 of the pot 2, so that seeds can be sown accurately.

22 is the entire case of the seeding device, with a hopper n on the top.
, and a divided supply port 15 is formed at the bottom of the hopper B,
A discharge port 16 is formed below the supply port 15 with a vertical gap, and a shutter 17 is installed between the supply port 15 and the discharge port 16.

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 is placed in each communication port 18.
When the communication port 18 matches the discharge port 16, the seeds 11 are dropped from the drop port 14 moving through the hose 19.

Reference numeral 20 denotes a drive device using a crank that moves the seeding device 12 in a circular direction as shown by the arrow (b), but since the crank itself is well known, its illustration is omitted.

Except for the special pot sheet 1, 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
Sowing in one seedling raising box 13 is completed by repeating the circular motion twice.

Since the seeding device ν moves in a circular manner as described above, the shutter 17 utilizes this to move the communication opening 18 of the shutter 17 within the range indicated by the bold line of the lowermost trajectory opening. The opening/closing drive mechanism 21 may be provided separately and opened/closed within the range shown by the thick line of the trajectory opening.

(effect) Next, we will discuss the effect.

When the distorted pot sheet 1 is placed on top of the storage board 8 which has a large number of protrusions 7 with the soil wall 5 facing down, the tips of the projections 7 of the mounting board 8 will protrude into the pot 2 through the through holes 6. become.

In this state, put a sieve ±9 from the -L side, press it from above so that it will not collapse even if it is turned over, and then invert the seedling raising box 1.
3 and turn it over with the opening of the seedling box, so that the mounting plate 8 is on top. When the upper mounting plate 8 is removed, the pot 2
A small recess 10 is formed inside the upper wall 5 of the container.

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 2. and the sixth
The state shown in the figure is that the drop opening 14 formed on the bottom plate of the seeding device is moved in a vertical circle as shown by the arrow (b) by a crank that rotates on the horizontal axis. 14
When it rotates once and approaches the top wall 5 of the pot 2, it starts to press the pot 2 from above, as shown by the thick line at the trajectory opening, and moves at the same speed as the pot 2. .

As mentioned above, when the drop opening 14 formed in the bottom plate presses the pot 2 from above, the pot sheet 1 becomes distorted.
The pot 2 also becomes flat and in close contact with the small depression 10 of the pot 2.

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 completely delivered to each small depression 10 through the hose 19 and the drop opening 14.

The seedling raising box 13 continues to move in the A direction, but since the sowing device ν is moving in a circle by the drive device, after sowing, it gradually moves away, rotates once, repeats this, and then moves on to the fifth and subsequent seedlings. Match the four small depressions 10 and perform the same sowing operation as before.

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

(Effects) In the conventionally known technology shown in Fig. 1, seeds E are limited to paddy, and 2.3 seeds are sown in covered soil Di.
It cannot be applied to potted Chinese cabbage seedlings. That is, since lettuce and the like are meant to stand alone, if 2 or 3 seeds are sown, they must be thinned out, which is very time-consuming and impracticable. For potted seedlings such as lettuce, it is required that only one seed be sown precisely in the center. In the case of Figure 1, seed E
It does not matter if the seedlings are sown at the edge of the covering soil, shifted as shown in the diagram. Therefore, it is used as seedlings for rice planting by sowing 2.3 seeds.

The one disclosed in Japanese Unexamined Patent Publication No. 63-237708 is a bell l
- A is placed on top of A, and a seeding device J is installed on top of it, but the defect of the known example is that the seeding device J itself is formed into an immovable structure, and in particular, the bottom part of the seeding device J is Since the opening K is an immovable structure, the seed E that falls through the drop opening at the bottom of the immovable structure is configured to fall into the small depression in the center of the moving pot A. There are times when it hits the small depression and does not fall.

In addition, many cardboard pot sheets are distorted, and since the distorted portion of a distorted cardboard pot sheet protrudes upward, it may get caught in the drop opening K at the bottom of the immovable structure.

However, the present invention provides a pot in which a pot sheet 1 is moved laterally at a constant speed by a transfer device, and seeds 11 are fed into small depressions 10 formed in the upper part of each pot 2 of the pot sheet 1 that is moving laterally. In sheet seeding equipment,
The drop opening 14 at the bottom of the seeding device is moved by a crank having a horizontal axis perpendicular to the moving direction of the pot sheet 1, so that the pot moves in a circular motion at the same speed as the pot 2 when it approaches the pot 2. Since this is a sheet seeding device, even a distorted cardboard pot sheet 1 can be flattened and seeds can be reliably sown in small depressions.
