It is something.

(Example) An embodiment of the present invention will be described with reference to the drawings. 1 is a paper pot sheet, 2 is a large number of bots formed vertically and horizontally on the paper pot sheet 1, and 3 is a substantially square paper board/l. ``This is a drawer-shaped storage box that is sized to fit two sheets 1 side by side.

The paper board 1 is made of a water-soluble paper material, and each board 2 has a substantially square shape when viewed from above, has a narrow lower end when viewed from the side, and has a through hole at the bottom. form 4.

The paper pot sheet 1 is fitted into the storage box 3 and receives covering soil into each pot 2, and the paper pot sheet 1 is supplied with covering soil on top of the covering soil.
Approximately 3 seeds are sown, bed soil is supplied on top of them, and the paper pot sheet 1 in this state is covered with a seedling box from above.
Flip over and remove storage box 3, which is now on top, and remove each bot 2.
When a seedling is placed in the gap and grown for a certain period of time, a bud will emerge upward from the through hole 4. 5 is a horizontal transfer table, which is formed long in the transfer direction. The horizontal transfer table 5 is provided with a plurality of guide rolls 6 that move the storage l9i3 at a constant speed at predetermined intervals.

A seed feeding device 7 is provided at the horizontal position of the horizontal transfer table 5.

The seed feeding device 7 is provided with a seed supply water bar 9 on the front side of the upper part of the frame 8.At the bottom of the seed supply hopper 9, an inverted grain flow board 10.11 is provided, and the grain is supplied by the flow grain board 1O111. A mouth 12 is formed. The tip of the grain board 11 is the supply port 12
The brush 13 is extended further and a sliding brush 13 is attached to the lower surface of the tip. The tip of the sliding brush 13 is brought into contact with the outer peripheral surface of a seed feed roll 14 rotating on a horizontal axis.

The seed feeding roll 14 has a larger diameter (
The 0-seed fitting recesses 15 are formed with a diameter of 200 mm to 300 mm and are spaced at predetermined intervals in the generatrix direction of the outer surfaces thereof. is formed.

A plurality of seed fitting recesses 15 are also formed at predetermined intervals in the circumferential direction, and a seed fitting recess 15 is connected to each other at the center of each seed fitting recess 15 formed in the circumferential direction. A slit 16 is formed in.

Reference numeral 17 indicates a rotating leveling brush 118 provided above the seed exuding roll 14 and on the downward rotation side.
Seed derivative 1 is in contact with the side surface of Seed derivative 1.

Reference numeral 19 denotes a scraping knife fitted in each of the slots 16, and even when reaching the seed falling portion 20, the seed fitting recess 1
This is to forcibly drop seeds that are stuck in the container and do not fall.

The base of the scraping knife 19 is attached to the rotating upward side of the seed feed roll 14, and the tip of the scraping knife 19 is placed as close as possible to the lower end of the seed guide 18 so that the five seeds can be placed in the seed falling section 20. Make it fall.

21 is the seed feeding roll 14 and the rotating leveling brush 1;
This is a motor that rotates the frame 7 and is attached to the frame 8.

Thus, the seed feeding roll 14 is attached with both ends of the rotation center shaft 22 of the seed feeding roll 14 being pivotally attached to the frame 8; It is attached to the horizontal transfer table 5 so that it can be changed between a position perpendicular to the transfer direction A of the storage box 3 and a position inclined at a predetermined angle.

That is, by changing the slight inclination of the seed feed roll 14 in the axial direction a-a, the preset spacing between the seed fitting recesses 15 can be adjusted wide and narrow. Paper bottles with different numbers of holes (horizontal and horizontal holes with different distances between the holes 2 and paper bottles with different numbers of holes 2) can also be used for seeding.

In this embodiment, 18 seed fitting recesses 15 are arranged in parallel,
The figure shows the situation when switching from placing the seeds directly above each row of the 18-row paper pot sheet L in the moving direction of the pot 2 (Fig. 5) to the case where seeds are sown on the 16-row paper pot sheet L. In this case, the inclination of the seed feed roll 14 in the axial direction a-a is made steep, and 16 of the 18 seed fitting recesses 15 are formed.

The inclination angle of the seed delivery roll 14 is changed by rotating the other end of the frame 8 by an arbitrary method around the pot 2 on one side. (Incidentally, it may be configured such that both left and right ends of the paper pot sheet 1 are rotated around the left and right center position.) Note that the paper pot sheet 1 is transferred by the guide roll 6 of the horizontal transfer table 5 by the seed feeding roll. Synchronize with rotation of 14.

Although this embodiment has been described using a seeding device for paper pot sheet 1, a pull-out seedling raising box is filled with bedding soil, grooves are formed in advance on the upper surface of the bedding soil, and grooves are formed in advance on the top surface of the bedding soil. A similar configuration can be used for row sowing in which seeds are sown in grooves, and the axial direction a-a of the seed delivery roll 14 is changed from a position perpendicular to the transport direction a of the storage box 3 to a position inclined at a predetermined angle. By doing so, the desired number of rows can be sown.

Also, below the seed falling portion of the seed feed roll 14 in the left and right direction? 1i [A fall guide with a number of divided drop ports arranged side by side may be provided, and in this case, several types of fall guides with different numbers of divided drop ports may be prepared.
Tax exchange Tru.

(effect) Next, we will discuss the effect.

When the storage box 3 fitted with the paper botton 1 is placed on the guide roll 6 of the horizontal transfer table 5, the guide roll 6
The storage box 3 is transported at a constant speed, the pots 2 of the paper pot sheet 1 are covered with soil, and the storage box 3 is further advanced to reach a position below the one-seed dispensing device 7.

Seed fitting recesses 15 are formed in a row at predetermined intervals in the generatrix direction of the outer peripheral surface of the seed feeding roll 14 of the seed feeding device 7, so that the seeds fit into each seed fitting recess 15.
Due to the rotation of the seed feed roll 14, the seeds reach below the rotating leveling brush 17, excess seeds are swept back by the rotating leveling brush 17, and only the seeds that fit into the seed fitting recess 15 are guided by the seed guide 18, 8 children fall from the fall section.

In this case, since the seed fitting recesses 15 are formed in one direction on the outer circumferential surface of the seed feeding roll 14 at predetermined intervals in a row, the guide roller of the water moth transfer table 5 When the transfer of the paper pot sheet 1 by 6 and the seed fitting recess 15 which is moved by the rotation of the seed feed roll 14 are synchronized, seeds fall from the seed falling section 20 into each boat 2 of the paper pot sheet 1. While the paper pot sheet 1 passes below the seed and the lower part of the basket ←: Total 2
It is sown in a pack of ~3 seeds.

In this sowing, the seed dispensing roll 14 is the seed dispensing roll! Both ends of the rotation center axis η of the seed feed roll 14 are attached to the frame 8, and the frame 8 is attached from a position where the axial direction a-a of the seed feed roll 14 is orthogonal to the transfer direction i of the storage box 3. Since the seeds are inclined at a predetermined angle, the seeds are not sown in the horizontal rows of pots 2 all at once, but are sown when each pot 2 reaches below each seed fitting recess 15 .

However, since the left and right widths of the paper pot sheet l are the same, if the pot 2 is small, for example, for 18 rows, the amount of bed soil will be insufficient and seedlings cannot be raised for a long period of time, If it is for 16 rows, which is small in number, the amount of bed soil per i@ will be large and the number of days for raising seedlings will be longer. Therefore, a dedicated seeding device corresponding to each paper pot sheet l is used.

In this case, the frame 8 to which the seed dispensing roll 14 is attached is arranged so that the axial direction a-a of the seed dispensing roll 14 is aligned with the storage box 3.
Since the frame 8 is attached to the horizontal transfer table 5 so as to be changeable between a position perpendicular to the transfer direction A and a position inclined at a predetermined angle, one end of the frame 8 can be attached to the center of the pot 2 on one side in an arbitrary manner. By rotating the other end to change the inclination of the seed feed roll 14 in the axial direction a-a, the distance between the seed fitting recesses 15, which is constant, can be adjusted wide and narrow. It is also possible to correspondingly sow seeds in paper pots (1) with different distances between the pots (2).

In the case of this embodiment, since 18 seed-fitting recesses 15 are provided horizontally (Fig. 5), if it is tilted so that two seed-fitting recesses z5 are left over, the 16-row paper pot sheet 1
Corresponding to pot 2, f! in the moving direction. True of column P, I:
The seed fitting recess 15 can be located in the seed fitting recess 15 (FIG. 6).

In addition, although this embodiment is explained using a seeding device for paper pot sheets, it is also possible to form row grooves in advance on the upper surface of the bed soil in the seedling raising box, and to sow m seeds in the grooves using the frame 8. By rotating the other end around one end using an arbitrary method to change the inclination of the seed feed roll 14 in the axial direction a-a, the distance between the seed fitting recesses 15, which is constant, can be widened or narrowed. Since the number of rows can be adjusted to, for example, 18 rows, 1
The number of rows can be changed, such as sowing 7 rows.

(Effects) Conventionally, in a seeding device, a seed feeding roll with seed fitting recesses formed at predetermined intervals on the outer circumferential surface is installed above a seedling box filled with bed soil that is transported horizontally. A seeding device is known in which the axial direction of the roll is orthogonal to the transport direction of the seedling box.

In the known method, since the position of the seed delivery roll is fixed, it is possible to sow only the number of rows that corresponds to the number of seed fitting recesses formed on the outer peripheral surface of the seed delivery roll. When changing the number of seeds and sowing, there was a problem in that the seed feed roll had to be replaced.

However, the present invention provides a seed feeder in which seed fitting recesses 15 are formed at predetermined intervals on the outer circumferential surface of a seedling box filled with bedding soil or a paper pot sheet filled with covering soil that is transported horizontally. In the seeding device equipped with a roll 14, the seed feeding roll 14 is configured to be freely changeable between a position perpendicular to the transfer direction A of the seedling box or paper pot sheet and a position inclined at a predetermined angle. Therefore, the distance between each seed fitting recess 15, which is constant, can be changed by simply changing the inclination of the seed feeding roll 14 in the axial direction a-a without replacing the seed feeding roll 14. It has the effect of making it possible to adjust the width and narrowing, and to change the number of rows or sow seeds on paper pot sheets with different numbers of pots.
