is formed. The coated lettuce seeds 11 are sown one by one in the depression 10.

In FIG. 6, there is shown a horizontal transfer table for transferring the mounting plate 8 fitted with the bot sheet 1, which is stored on the floor by supporting legs 13 provided at desired positions.

At the starting end of the horizontal transfer table, there is a seat l.
A supply section 24 is formed to supply the mounting plate 8 fitted with the mounting plate 8. Each bot 2 of the pot sheet l is placed in front of the supply section 24.
A soil supply device M14 is provided for supplying sieved soil 9 in a finely divided manner.

The soil supply device 14 is well known and consists of an upper sieved soil supply hopper 15 and a lower delivery belt 16.

A first pressure roll 17 is provided on the front side of the metal supply device N14. The first crushing roll 17 once crushes the sieve soil 9 supplied by the single-layer supply device 14, and the protruding roll 1 to be described later

Reference numeral 45 denotes frames 30°3 on the left and right sides of the guide plate 40.
It is a long guide rod provided between the storage plate 8 and the top surface of the storage plate 8 and the upper surface of the guide plate ω, and forms a gap between the bottom surface of the storage plate 8 and the top surface of the guide plate ω, and the downward rotation of the transfer protrusion side described above is made smooth by this gap. .

Said protrusion roll! 8, a leveling brush 46 is provided on the front side. That is, when the pressing protrusion 19 is fitted into the bot 2, the sieve soil 9 inside the pot 2 protrudes and protrudes from the upper surface of the connecting part 4 of the bot 2 by ±47, while the inside of the pot 2 Since a recessed portion is formed on the upper surface of the sieved soil 9, the protruding portion ±47 is swept back to the rear by the leveling brush 46 so that it enters the recessed portion 6.

The leveling brush 46 is attached to the arm 4 attached to the horizontal transfer table 12.
9 is horizontally rotated @150, and rotated by a motor.

Further, the placing plate 8 is formed thickly to compress the supplied floor, but the seedling raising box 61 that is not pressed is formed thinner than the placing plate 8, and therefore the leveling brush 46 can be adjusted in height. When supplying bed soil, it is located at a high position, and when supplying upper layer, which will be described later, it is located at a low position.

Accordingly, a cross-over board 51 is provided in the left-right direction on the upward rotation side of the leveling brush 46.

It is attached to the arm 49.49, and it slopes lower toward the rear. The front end of the cross-over board 51 is brought into contact with the leveling brush 6 W1, and the rear end of the cross-over board 51 is located behind the above-mentioned distance.

Following the leveling brush 46, wIJ2 pressure roller 52
will be established. The second W4 pressure roller 52 has a leveling brush 46
The sieved soil 9 that has been leveled is further compressed and tightly packed into the pot 2.

Next to the second pressing roller 52, a reversing part sill is provided for covering and reversing the seedling raising box 61 from above on the upper surface of the pot sheet l fitted on the above-mentioned placing plate 8, and following the 1st reversing part leap, there is an upwardly recessed part. A sowing device 9 is provided to ensure that seeds 11 are sown one by one in a seed 10.

Therefore, a pot sheet pressing device % is provided on the rotating upward side of the leveling brush 46. Between the pot sheet pressing devices, the front end of the pot sheet 1 to which sieve soil 9 is not supplied is lifted by the leveling brush 46 and prevented from wrapping around the leveling brush 46.

Pot seat presser! t56 is formed by providing a plurality of presser plates 57 at intervals on the lower surface of the transfer plate 51 so as to be positioned above the longitudinal connecting portions 4 of the pot sheet 1. The presser plate 57 has a lower surface parallel to the upper surface of the pot sheet 1, and a rear end thereof is inclined to become higher toward the rear to form a guide wing. The lower surface of the presser plate 57 is positioned above the lower end of the brush mark of the leveling brush 46, and the tip of the presser plate 57 is positioned below the center of the leveling brush 46.

In the figure, reference numeral 5 denotes a transfer roll that transfers the mounting plate 8 following the transfer device 3.

(effect) Next, we will discuss the effect.

When the pot sheet l is placed on the top of the loading plate 8 which has a large number of projections 7 with the upper wall 5 facing down, the tips of the projections 7 of the loading plate 8 come to protrude into the pot 2 from the through holes 6. . When the pot sheet l in this state is supplied onto the guide @45. The soil feeding device 14
When passing under the sieve soil 9, each pot 2 is over-supplied with sieve soil 9, and the rate of supply is such that it covers each pot 2 thickly.

The pot sheet 1 that has been supplied with the sieved soil 9 is once compressed by the first pressing roll 17 and reaches below the protruding roll 18 . Since the pot sheet 1 is moved by the transfer protrusion side of the endless transfer chino 28 that rotates in synchronization with the protrusion roll 18, the pressing protrusion 19 of the protrusion roll 18 does not press the pot 2 and is press-fitted into the pot 2. Press only the sieved soil 9 from above to harden it.

At this time, due to the intrusion of each pressing projection 19, each pressing projection 19
The sieve soil 9 around the pot 2 protrudes to form a protrusion ±47 on the connecting portion 4 of the pot 2, and a recess is formed on the top surface of the center of the pot 2.

Next, when the mounting plate 8 reaches below the leveling brush 46, the protruding ±47 is returned to the concave narrow circle by the leveling brush 46, and then when it reaches below the second pressing roller 52, the second time is applied. The pressure is applied, and the sieve soil 9 in the pot 2 is solidified so that it will not spill even if it is turned over once.

In this case, on the transfer protrusion side, the same distance as one pot 2 is maintained between the rearmost pot 2 of the preceding pot sheet 1 and the frontmost pot 2 of the succeeding pot sheet 1, so that the transfer is carried out. , the overhang ±47 which is returned by the leveling brush 46 falls into the heat during said period. A cross-over plate 51 is provided in the left-right direction on the rotational upward side of the leveling brush 46, and the front end of the cross-over plate 51 is provided in sliding contact with the leveling brush 46, so that the cross-over plate 51 and the preceding pot sheet l The top surface and leveling brush 46
The leveling brush sweeps back all protruding ±47 of the upper surface of the connecting portion 4 of each pot 2 of the preceding pot sheet 1 to fill the space A formed by the above. This filled soil enters into the leveling brush 46 and rotates together, and accumulates on the top surface of the cross-over board 51. The soil that accumulates on the top surface is later pushed by the soil that rotates together with the leveling brush 46, and becomes soil. It falls from the rear end of the spanning board 51 and falls into the pot 2 at the front end of the succeeding pot sheet 1.

Therefore, following the second tI4 pressure roller 52, the reversing section 5
3 is provided, and in the reversing section 53, the inverted seedling growing box 61 is placed on top of the pot sheet l, the whole seedling growing box 61 is turned over, and the upper storage board 8 is removed. Even if the pot 2 is formed to have about four times the volume, the pot sheet 1 can be turned over without any spillage because the soil is compacted three times.

Then, the recess 10 inside the upper wall 5 is turned upward, and the seeding device 1
9, seeds 11 are sown in each depression 10,
The sown seedling raising box 61 is again supplied to the horizontal transfer table 12, and top soil is supplied between each pot 2 (FIG. 13).

Therefore, if the sieved soil 9 in the hopper 15 of the soil supply device 14 runs out while the placing plate 8 fitted with the pot sheet 1 is being transferred, the pot sheet 1 to which the sieved soil 9 is not supplied is light, and the pot is light. Because the sheet 1 is distorted and floats up, and the leveling brush 46 rotates in the opposite direction to the direction of travel of the pot sheet 1, the front end of the pot sheet 1 is lifted by the leveling brush 6, and the leveling brush 46 Sometimes it gets wrapped around.

Also, leveling brush is used when supplying bed soil.

Since the placement plate 8 is thick, it is placed in a high position, and when feeding the upper grades, the seedling raising box 61 is thinner than the storage plate 8, so it is placed in a lower position. Even when the leveling brush 46 is positioned and the storage plate 8 fitted with the pot sheet 1 is transferred, the leveling brush 46 is at a low position.

The pot sheet l may wrap around the leveling brush 46.

In the present invention, the lower surface side of the dowel plate 51 is formed parallel to the upper surface of the pot sheet 1.

The rear end is provided with a bot sheet pressing device enclosure consisting of a pressing plate 57 having a guide portion ○ that slopes upward toward the rear, and the lower surface side of the pressing plate 57 is connected to the leveling brush 46.
Since it is positioned above the lower end of the brush mark, even if the pot sheet 1 to which no sieve soil 9 is supplied is transferred, the front end of the pot sheet 1 is guided by the guiding part 9,
Passes below the bottom side. Therefore, pot sheet 1
to prevent it from wrapping around the leveling brush 46.

Similarly, even when the leveling brush 46 is at a low position, the pot sheet 1 is held down by the pot sheet pressing device, thereby preventing it from wrapping around the leveling brush.

(Effects) In the present invention, a large number of pots 2 are connected vertically and horizontally to form a pot sheet 1, and a soil supply is provided to supply sieved soil 9 to the pot sheet 1 at a position above the transfer path of the pot sheet 1. Device 1
4, a pressing roll 17 that presses the sieved soil 9 supplied to the pot sheet 1, and a pressing protrusion 1 that presses the pressed sieved soil 9 at the center of the pot 2 to a medium degree to form a recess 48.
9 provided on the circumferential surface of the protrusion roll 18, and the pressing protrusion 19.
A leveling brush 46 is provided for returning protrusion ±47 that occurs when forming the recess side into the recess side.

A bridging plate 51 is provided on the rotating upward side of the brush 46, the tip of the bridging plate 51 faces a position below the center of the brush 46, and the lower surface side extends rearwardly from the upper surface of the pot sheet 1. Since this is a pot sheet seeding device equipped with a pot sheet pressing device having a desired number of fixed pot sheet pressing plates 57 each having a shape such as , even if the front end of the pot sheet l is transported with it floating,
The front end of the pot sheet 1 is guided downwardly on the lower surface side by the guiding portion side of the presser plate 57 and passes, thereby preventing the pot sheet 1 from wrapping around the leveling brush 46.

(2) Furthermore, even if the leveling brush 46 is erroneously placed at a low position, the pot sheet presser device prevents the pot sheet from wrapping around the leveling brush 46.

This effect is achieved.
