Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pot sheet seeding device that 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, add bed soil F, cover seedling box G upside down,
It is known that the seedlings H are grown in pots by removing the mounting plate C which has been turned over and placed on top.

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.

(Problems to be Solved by the Invention) The one in Fig. 1 is for a rice transplanter, and the seeds E used are limited to 2.3 grains of paddy sown, 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 seeds E are sown at the edge of the covered soil, shifted as shown in the figure.

Therefore, it is used as seedlings for rice planting by sowing 2.3 seeds.

Therefore, in the case of lettuce seedlings, you can grow them by inverting them as shown in Figure 1, but you should first form a small hole in the center of the top of the bot and sow only one coated seed there. I have to. Also, lettuce seedlings) A
is approximately four times larger than the product.

The device disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 63-237708 has the bot A placed on the belt ■, and a seeding device J provided above it, but in the known example, the bot A is not reversed. It is.

When reversing something that is about four times as large as bot A, there is a problem that the internal floor F spills out during the reversal.

This problem can be solved by compacting the soil, but the present invention specifically compacts the soil in two stages to prevent spillage.

forms a pyramid or cone as a whole. 6 is a through hole formed in the center of the upper wall 5.

The bot sheet 1 is placed on a mounting plate 8 having a large number of protrusions 7, as shown in FIG. Then, a large number of protrusions 7 protrude into each bot 2 from the through hole 6. When the sieve soil 9 is filled from above in this state, a small hole 10 is formed inside the through hole 6 as shown in FIG. 3 because many protrusions 7 protrude into the pot 2. The coated lettuce seeds 11 are sown one by one in the small cold area 10.

2 is a transfer device that transfers the mounting 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 y includes the above-mentioned placement plate 8.
A belt conveyor or transfer roll is provided to transfer the .

A soil supply device 14 is provided above the transfer device for supplying a slightly multi-mesh sieve ±9 to each bot 2 of the potsie 1. The soil supply device 14 is well known and includes an upper sieved soil supply hopper 1.
5 and a lower dispensing bell) 16 (Means for Solving the Problem) Therefore, the present invention provides a method for placing a pot sheet 1 formed by connecting a large number of bots 2 vertically and horizontally with the top wall 5 of the bots 2 facing down. At a position above the transfer device arrangement of the mounting plate 8 to be placed, there is provided a protrusion roll 17 having pressing protrusions 9 formed on its outer circumferential surface for press-fitting into the pot 2 from above and solidifying the sieves ±9 in the pot 2, Following the protrusion roll 17, a leveling brush ρ was provided to restore the protrusion ±B that occurs when the pressing protrusion presses the sieve soil 9, and a pressure roller n was provided following the leveling brush η. This is a seeding device for bot sheets.

(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 bots 2 for stocks are used.
The bottom portions 3 of are connected vertically and horizontally by connecting portions 4 to form a rectangular shape. Since the bot 2 of the present invention is used for painting lettuce, it is formed to have a volume approximately four times larger than that for painting.

Reference numeral 5 denotes the upper wall of the bot 2, which has the shape of the side surface of the bot 2.

A protruding roll 17 is provided on the front side of the soil supply device 14. The protruding roll 17 is mounted on a horizontal rotation axis perpendicular to the conveying direction of the pot sheet l, and the outer peripheral surface of the roll 19 portion of the protruding roll 17 is press-fitted into the pot 2 of the pot sheet 1 and sieved with soil. A pressing protrusion is formed to harden the part 9.

The protrusion roll 17 rotates in synchronization with the movement of the bot 2,
The pressing protrusions are fitted into each pot 2 one by one, and only the sieves ±9 are pressed from above, and each pot 2 is not pressed.

If the sieve soil 9 adheres to the pressing protrusion of the protrusion roll 17, the sieved soil 9 in the pot 2 cannot be reliably pressed. Scrape off the sieve ±9 adhering to the protrusions.

A leveling brush η is provided following the protruding roll 17. That is, when the pressing protrusion is fitted into the bot 2, the sieve ±9 in the pot 2 protrudes and becomes soil n on the top surface of the connecting portion 4 of the bot 2, while the sieve in the bot 2 Since a concave portion 24 is formed on the upper surface of ±9, the protruding portion ±B is swept back by the leveling brush η so that it enters the four portions 24.

The leveling brush η is mounted on an arm δ attached to the transfer device by a horizontal rotating shaft, and is rotated by a motor.

A pressing roller I is provided following the leveling brush η. The pressure roller η is the sieve leveled by the leveling brush η.
9 is further compressed and packed tightly into pot 2. The pressure roller n is mounted on an arm attached to the transfer device by means of a horizontal rotating shaft.

Following the pressure roller n, an inversion part I is provided to cover and invert the seedling box from above on the upper surface of the sheet 1 fitted to the above-mentioned mounting plate 8, and A sowing device 31 that reliably sows seeds one by one in each seedling.
will be established.

(effect) Next, we will discuss the effect.

A clay wall is placed on the top of a mounting plate 8 having a large number of projections 7 to prevent spillage even when the plate is turned upside down.

An inversion part (9) is provided following the pressure roller a, and in the inversion part I, an inverted seedling growing box is placed on top of the bot sheet 1.
The whole seedling raising box is turned over and the upper mounting plate 8 is removed.In this case, even though the bot 2 is formed to have a volume approximately four times that of the one for loading, the soil compaction is carried out twice as described above. Therefore, the pot sheet 1 can be turned over without spilling soil.

Then, the hand kneaders 10 inside the upper wall 5 are turned upward and reach below the seeding device 31, and the seeds 11 are sown into each hand kneader 10.

(Effects) The one in Figure 1 is for a rice transplanter, and the seed E used is limited to 2.3 seeds of paddy sown, 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, when the pot sheet 1 is placed with its 5 side facing down, the tips of the protrusions 7 of the mounting plate 8 will protrude into the pot 2 from the through holes 6.

When potsie) 1 in this state is supplied to the transfer device η,
When passing under the soil supply device 14, each bot 2 has a sieve.
9, but the proportion of the supply is such that it overlaps each bot 2 thickly.

When the bot 2 to which the sieve soil 9 has been supplied reaches below the protruding roll 17, the protruding roll 17 has a structure in which a pressing protrusion that fits into each bot 2 is formed on the outer peripheral surface of the roll 19. The front part of the pressing protrusion presses into the boat 2 and presses the sieve ±9 from above to harden it. At this time, the sieve soil 9 in front of each pressing protrusion protrudes to form a protrusion on the connecting part 4 of the bot 2, and a four part 24 is formed on the upper center surface of the bot 2.

Subsequently, when it reaches below the leveling brush η, the protruding ±B is returned to the recess 24 by the leveling brush η, and when it reaches below the pressing roller n, it is pressed for the second time, and the pot z When hardening the inner sieve ±9, it does not matter if the seeds E are sown at the edge of the covered soil as shown in the diagram.

Therefore, it is used as seedlings for rice planting by sowing 2.3 seeds. Moreover, the size of the lettuce seedling bot A is about four times larger than the total size.

The one in Japanese Patent Application Laid-open No. 63-237708 is Bell)
Bot A is placed on I and a seeding device J is provided above it, but in this known example, the bot A is not turned over.

B) When inverting something that is about 4 times larger than A, there is a problem that the internal soil F spills out during the inversion.

However, in the present invention, a bot 1 formed by arranging a large number of bots 2 vertically and horizontally is placed at one position of the transfer device 21L2 of the mounting plate 8 on which the bot 2 is placed with the top wall 5 of the bot 2 facing down. A protrusion roll 1 having a pressing protrusion front formed on the outer circumferential surface for press-fitting into the pot 2 from the L direction and solidifying the sieved soil 9 in the pot 2.
7, and following the protrusion roll 17, a leveling brush η is provided for returning the extruded soil n generated when the front of the pressing protrusion presses the sieve soil 9, and a pressure roller is provided following the leveling brush η. Since this is a pot sheet seeding device equipped with a pot sheet 1, in the reversing section (9), the inverted seedling raising box is placed on top of the pot sheet 1, the seedling raising box is inverted, and the placing plate 8 is turned upward. However, in this case, even though the pot 2 is formed to have a volume approximately four times that of the original pot, the soil is compacted twice, so the pot sheet 1 can be turned over without soil spillage.
