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 large number of pots A are arranged in rows and columns and made of cardboard. Place,
Put the covering soil in each box) A.

It is known that seeds E are sown on a covering soil, then bed soil F is put in, a seedling raising box G is placed on top, the seedling raising box G is placed on top, the seedling raising box G is turned upside down, J and the placing plate C are removed, and the seedlings are grown into potted seedlings H.

Also, in Japanese Patent Application Laid-open No. 63-237708 (Figure 2),
It is described that a bell) A is placed on a bell) Lh, and a seeding device J is provided above it.

(Problem to be solved by the invention) The one in Figure 1 is for a rice transplanter, and the seeds E used are limited to paddy seeded with two or three seeds, and cannot be applied to potted seedlings of lettuce, cabbage, or Chinese cabbage. .

That is, since lettuce and the like are grown as single plants, if 2.3 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 one seed E is sown at the edge of the covered soil as shown in Fig. 1.

Therefore, it is used as seedlings for rice planting by sowing two or three grains of one seed paddy.

Therefore, in the case of lettuce seedlings, the method of growing lettuce seedlings is by inverting the pot as shown in Figure 1, but by forming a hand seedling in the center of the upper part of the pot in advance and sowing only one coated seed there. That's what I do.

The one disclosed in Japanese Unexamined Patent Publication No. 63-237708 is a bell h
Bottle A is placed on top of I, and a seeding device J is provided above it. However, the defect of the known example is that the seeding device J itself is formed into an immovable structure, and in particular, the drop opening at the bottom is Since K is an immovable structure, the structure is such that the seeds E that fall through the drop opening at the bottom of the immovable structure fall onto the center of the moving bog A. Sometimes it doesn't hit and fall due to the central hand.

The present invention allows lettuce seeds to be accurately sown one grain at a time, continuously in a hand pattern previously formed at the center of the upper part of the pot, even in continuous operation.

(Means for Solving the Problems) Accordingly, the present invention moves a pot sheet 1 in which a large number of pots 2 are arranged vertically and horizontally at a constant speed by a transfer device M12, and moves the pot sheet 1 of the pot 2 of the moving pot sheet 1 at a constant speed. In a pot sheet seeding device that feeds seeds 11 per 1 degree of hand strain formed at the top, the bottom of the seeding device has a lateral number indicating the number of pots in the lateral direction of the pot sheet 1. and the number in the vertical direction is an integer fraction of the number of pots in the vertical direction of the pot sheet 1, forming a drop [130R'1], and the front group of drop ports moves repeatedly at the same speed as the pot 2. The transfer device has a space between the rear end 34 of the leading pot seat 1 and the front end of the trailing pot seat 1, the same width as the front group of drop ports. This seeding device for pot sheets is provided with a transfer protrusion for transporting seeds 11, and when the group of drop openings is located on the above-mentioned interval, the falling path for the seeds 11 is automatically closed.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. L is a pot sheet made of paper material, and a large number of pots 2 for each stock are
Since the pot 2 of the present invention is made of lettuce Ichikawa, the pot 2 is formed into a rectangular shape by vertically and horizontally connecting the bottom portions 3 of the pot 3 with connecting portions 4, so that the pot 2 has a volume approximately four times larger than that for rice.

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 top of a bamboo board 8 having a large number of protrusions 7, as shown in FIG. Then, a large number of protrusions 7 protrude into each pot 2 from the through hole 6. When the sieved soil 9 is filled from above in this state, a large number of protrusions 7 protrude into the pot 2, so that a hand sieve 10 is formed inside the through hole 6, as shown in FIG. The coated seeds 11 of lettuce or the like are surely sown one by one in the hand seed 10.

The carrier is a transfer device that transfers the placing plate 8 on which the pot sheet 1 is fitted, and is placed on the floor by supporting legs 13 provided at desired positions. The transfer device tL2 is provided with a transfer conveyor 14.

Transfer device! At a position above the starting end of the pot sheet 1, there is a soil supply device 15 that supplies a sieve with a slightly large mesh size of ±9 to each pot 2 of the pot sheet 1.
will be established. The soil supply device 15 is well known and consists of an upper sieved soil supply hopper and a lower delivery belt.

A protruding roll 16 is provided following the soil supply device 15.

The protruding roll 16 is mounted on a horizontal rotating shaft 17 perpendicular to the conveyance direction of the pot sheet l, and is press-fitted into the pot 2 of the pot sheet l on the outer peripheral surface of the protruding hole 16 to pass through the sieve ±9.
Forms pressure protrusions that harden. The projection roll 16 rotates in synchronization with the movement of the pot 2, and the pressing projections fit into each pot 2 one by one to press only the sieve ±9 from above.
Each pot 2 is not pressed.

A leveling brush 19 is provided following the protruding roll 16.

The leveling brush 19 removes the soil pushed out from the upper surface of the connecting portion 4 of the pot 2 when the pressing projection is fitted into the pot 2, and removes the sieved soil 9 in the pot 2 formed by the pressing projection. Sweep it back into the recess on the top surface.

A pressure roller 9 is provided following the leveling brush 19.

The pressure roller further compresses the sieve ±9 that has been leveled by the leveling brush 19 and packs it tightly into the pot 2.

Following the pressure roller, an inversion part 21 is provided on the upper surface of the pot sheet l fitted on the above-mentioned placing plate 8 to cover and invert the seedling growing nodes from above. Seed inside! A sowing device that sows one seed at a time! t22 is provided.

n is the entire case of the seeding device η, with a hopper 24 on the top
, and a divided supply port is formed at the bottom of the hopper 24,
A discharge n3 is formed by placing a vertical gap below the supply port δ,
A shutter n is installed between the supply port δ and the discharge n3.

1 is a communication port formed in the shutter n, and when the supply port δ and the communication n6 match, one seed 11 fits into each communication port n, and when the communication port n6 matches the discharge n3, it moves through the hose device. Seeds 11 are dropped from the drop opening I. Falling port (9
) is formed in the falling part 31 provided at the lower part of the case B with the same spacing as the through holes 6 of the pot seam )1.

g is any drive device that repeatedly moves the entire seeding device η, whether using a crank or a link mechanism,
Other known mechanisms may also be used.

Except for special pot sheets 1, normally two pot sheets 1 each having pots 2 arranged in 10 rows and rows are lined up vertically and 1!
Therefore, the number of pot 2 is 10 horizontally and redundant vertically.

The drop port (9) formed in the drop portion 31 of the embodiment is as follows.

There are 10 seeds horizontally and 4 seeds are arranged vertically in parallel so that 11 seeds can be sown in 4 rows of pots 2 at a time, so 5
Seeds are sown on one pot sheet of a seedling box (in one repetition).

If the leading seedling raising box north and trailing seedling raising box Oto are transferred by the transfer conveyor 14 without any gap as in the past, the pot sheet l between the leading seedling raising box wing and the trailing seedling raising box head does not exist. Not only will you be sowing seeds in the area;
Since the positions of the pot 2 and the drop opening blade do not match, the transfer protrusion A of the transfer conveyor 14 is placed between the rear end of the leading seedling growing box and the north front end 5 of the trailing seedling growing box. During the transfer, the sowing is interrupted and the pot 2
and prevent the position of the drop opening blade from shifting.

Accordingly, the shutter n is operated by an arbitrary interlocking mechanism (a detection mechanism using a well-known optical sensor or a mechanical device).
Discharge n only when the seedling box n passes below the falling part 31
5, and close it when the distance is above to prevent seeding.

The opening/closing mechanism of the shutter n may be based on the movement of the seeding device η, or a separate opening/closing drive mechanism g may be provided to open and close the shutter n.

(effect) Next, we will discuss the effect.

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

When the mounting plate 8 fitted with the pot sheet l in this state is supplied to the starting end of the transfer device f112, since the transfer device 712 is provided with the transfer protrusions I at the above-mentioned intervals, the pot sheet 1 is The sieve ±9 is introduced from above below the soil supply device 15 and is pressed by the suppressing protrusion.

The excess sieve ±9 on the top surface of the pot sheet l is swept back with the leveling brush 19, and the pressure roller 9 is used to press it down, and the inverted seedling box proverb is placed on top of the pot sheet l using the reversing section 21 to raise the seedlings. When the box n is reversed, the a placement plate 8 becomes one hit. 4 made it to the top! When the placing plate 8 is removed, a pot 2 with a small depression 10 formed inside the upper wall 5 is obtained.

When it is further transferred by the transfer device M12, it reaches below the seeding device η. Meanwhile, the pot sheet 1 is moved at a constant speed in the A direction by the transfer conveyor 14, and the seeding device η is
Drive device! Since the sowing device η moves repeatedly in the A direction, it moves at the same speed as the seedling m33, and the four drop openings formed in the dropping part 31 at the lowest end of the sowing device η in the transfer direction (9) will move while remaining aligned with the small depressions lO of the four pots 2.

Therefore, when the seeding device η moves in the A direction, an arbitrary automatic opening/closing drive mechanism g is activated to discharge the shutter n.
9, one seed 11 is supplied to each small depression 10 through a hose and a droplet.

The movement of the seedling box wings continues, but the seeding device η is moved entirely in the anti-A direction by the drive device 32 and then repeats the above movement in the A direction, so next, the seedling box blades are moved in the 5th and subsequent four directions. Matching the small depression 10, it is a double seedling box again! Both the seeding device 3 and the seeding device 2 move in the direction A at the same speed and perform the same seeding work as before.

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

When the falling part 31 of the seeding device B sows seeds in the last four small depressions 10 on the rear side of the preceding seedling raising box, the seeds are then sown in the trailing seedling raising box. , the four small depressions 10 on the other side of the front end of the trailing seedling raising box wing do not match with the drop opening 30 group of the seeding device η, but in the present invention, the transfer conveyor 14 is located at the rear end of the preceding seedling raising box n. Since the structure is such that the part and the front end of the trailing seedling raising box are transferred with the same width as the group of drop opening blades, they always match accurately. Since the shutter n is designed to close at intervals of 5, it does not supply 1 seed 0, and when it coincides with the succeeding seedling raising box and the falling part 31, it is determined that the seed JJJ1 is placed in the pot of the pot sheet l. Each small depression inside 2! 0
Continuous sowing is possible only in

(Effect) Conventionally, as shown in Fig. 1, a cardboard pot sheet B with a large number of pots A arranged vertically and horizontally was placed on a placing plate C for 1 s! ! Place the seedling box G on top, turn it upside down, remove the storage board C, and plant the seedlings. Potted seedlings H are known. Furthermore, Japanese Patent Application Laid-Open No. 63-237708 (FIG. 2) describes a pot A placed on a bell I and a seeding device J provided at the -L portion thereof.

However, the one in Figure 1 is for a rice transplanter and cannot be used for potting lettuce, cabbage, or Chinese cabbage.In addition, the one disclosed in JP-A No. 63-237708 has a drop opening K at the bottom that is immovable. Because of the structure, the seeds E that fall through the drop opening at the bottom of the immovable structure are configured to fall into the small depression at the center of the moving pot A, and may not fall into the small depression.

However, in the present invention, a pot sheet 1 in which a large number of pots 2 are arranged vertically and horizontally is moved at a constant speed by a transfer device, and small depressions 10 formed at the tops of the pots 2 of the moving pot sheet 1 are In the pot sheet seeding device for supplying seeds 11, the number of pots in the horizontal direction is equal to the number of pots in the horizontal direction of the pot sheet 1, and the number of pots in the vertical direction is equal to the number of pots in the horizontal direction of the pot sheet 1. Forming 30 groups of drop ports, which are one integer fraction of the number of pots in the vertical direction,
The group of drop ports 30 is formed to repeatedly move at the same speed as the pot 2, and the transfer device has a gap between the rear end U of the preceding pot sheet 1 and the front end of the trailing pot sheet 1. A transfer protrusion having a PIJllWIL having the same width as the drop opening blade group is provided at the drop opening, and when the drop opening 30 group is on the above-mentioned interval, the falling path for the seeds 11 is automatically closed. Since it is a seeding device for pot sheets, continuous seeding can be performed smoothly as described above.
