[0013]

[Operation] Next, the operation will be described. Pot sheet 1 for seedling box 7
When it is supplied to the transfer table 10 in a state of being fitted to the first soil scraper 1, the floor soil supply device 13 supplies the floor soil 8 to the first scraper 1
6, the first scraper 16 reaches the pot sheet 1
Of the floor soil 8 supplied above, the floor soil 8 above each pot 2 is left by the cutout portion 19, and the floor soil 8 between the pots 2 and 2 is flattened by the first sweeping portion 20. To

Therefore, the first compression roller 23 can compress the relatively large amount of the soil 8 above the pot 2 to the position of the upper surface 3 of the pot sheet 1 as much as possible.
The floor soil 8 can be pushed in.

In this case, the floor soil 8 enters the pot 2 through the through hole 4 in the upper surface 3, but since the lower portion of the pot 2 is formed wider than the size of the through hole 4, it is simply pushed from above. However, it may not be possible to press it sufficiently.

According to the present invention, the second scraper 2 having substantially the same structure as the first scraper 16 is provided on the front side of the first compression roller 23.
6, the cutout portion 19 of the first scraper 16 is provided.
Soil 8 that has been compressed by the first compression roller 23 after passing through
When the pot sheet 1 approaches the second scraper 26, the pot sheet 1 is scraped by the lower edge of the second scraping portion 27 of the second scraper 26 and guided by the second scraping portion 27 that is inclined when viewed from above. The cutout portion 19 reaches and passes through the cutout portion 19 and reaches the lower portion of the second compression roller 30 in the same state as when the floor soil 8 is supplied again above the pot 2 to reach the second compression roller 3
0 pushes it into pot 2.

Therefore, the floor soil 8 in the pot 2 is simply 2
Not only is the pressure suppressed once, but also the pressure is suppressed while the bed soil 8 is being replenished by the second scraper 26, so that the floor soil 8 is reliably and evenly supplied into each pot 2.

However, in the present embodiment, the lower edge of the second scraping portion 27 between the notches 19 of the second scraper 26 is formed lower than the lower edge of the first scraping portion 20 of the first scraper 16. Therefore, even if the pressure is suppressed by the first pressure suppressing roller 23, the floor soil 8 between the pots 2 is further scraped by the lower edge of the second scraping portion 27 of the second scraper 26, and as described above. The second scraping portion 27, which is inclined when viewed from above, reaches the notch portion 19 and passes through the notch portion 19, and the floor soil 8 is supplied above the pot 2 again.
It reaches below the compression roller 30 and is pushed into the pot 2 by the second compression roller 30. Therefore, the second scraper 26 surely replenishes the floor soil 8 above the pots 2, so that the floor soil 8 can be evenly supplied into each pot 2.

The excess soil of the pot sheet 1 that has passed below the second pressure roller 30 is removed by the rotating and leveling brush 31, and the supply of the floor soil 8 is completed. The height relationship between the first scraping portion 20 of the first scraper 16 and the second scraping portion 27 of the second scraper 26 and the peripheral wall 32 of the seedling raising box 7 should be such that they do not interfere with each other. For example, the first
When the scraper 16 and the second scraper 26 are formed of an inelastic member, the lower edge of the second scraping portion 27 of the second scraper 26 may be above the upper edge of the peripheral wall 32 of the nursery box 7, When the first scraper 16 and the second scraper 26 are formed of elastic members, the scrapers of the scrapers 16, 16 and 26, the lower edges of the scrapers 20, 27 and the nursery box 7
Independent of the surrounding wall 32 of each scraper, 16,
26 scraping parts, the lower edges of 20, 27 are the peripheral walls 3 of the nursery box 7.
It deforms by touching 2 and returns to its original position when it gets over it. Therefore, the relationship between the height of the peripheral wall 32 of the seedling raising box 7 and the upper surface 3 of the pot 2 is arbitrary as long as the above relationship is satisfied.

Further, the first scraping portion 2 of the first scraper 16
The relationship between the lower edge of 0 and the upper surface 3 of the pot 2 is that the floor soil 8 directly above the pot 2 and the floor soil 8 above the pot 2 remain relatively above the pot 2. It is good if there is a height relationship, again. The second scraping portion 27 of the second scraper 26 is the first
It suffices to position the scraper 16 lower than the first scraping portion 20, and the scraping portions 20, 20 of the scrapers 16, 16, 26,
The lower edge of 27 and the upper surface 3 of the pot 2 are independent. However, in the present embodiment, the second scraping portion 2 of the second scraper 26 is
The lower edge of 7 is positioned lower than the upper surface 3 of the pot 2 so that the soil between the pots 2 is scraped off, and an unnecessarily large amount of floor soil 8
Is supplied so as not to waste it (the soil supplied between the pots 2 is referred to as eye soil, but this may be supplied separately).

[0021]

According to the present invention, the pot sheet 1 in which the lower surface side of the pot 2 in which the upper surface 3 has the through hole 4 and the upper surface 3 side is narrow and the lower surface side is wide is connected, and the pot sheet 1 is connected to the upper surface 3 A transfer table 10 that is horizontally transferred upward, a floor soil supply device 13 that is provided above the transfer table 10 and that can supply the top soil of the pot sheet 1, and the floor soil that has been supplied onto the pot sheet 1 is suppressed. With the crushing roller 23, the floor soil above the pot 2 is left on the lower side in the transfer direction of the floor soil supply device 13, but the floor soil in the portion between the pots 2 is scraped out. The notch 19 is provided at a portion corresponding to the upper portion of the pot 2, and the scraping portion 2 is provided at a portion corresponding to the portion between the pots 2.
The first scraper 16 having the number 0 is provided, the compression roller 23 is located on the lower side of the first scraper 16, and the second scraper 26 and the second compression roller 30 are similarly formed on the lower side of the compression roller 23. A pot sheet soil supply device provided with the above, and in the above, the second scraper 26
The second scraping portion 27 formed in the first scraper 16 is projected lower than the scraping portion 20 of the first scraper 16, and the soil supplying device for the pot sheet, and in the above, the first scraper 16 and the second scraper 26 are Pot sheet 1 as seen from above
Since it is a pot sheet soil supply device that is provided to be inclined with respect to the transfer direction, the floor soil 8 that passes through the cutout portion 19 of the first scraper 16 and is pressed by the first pressing roller 23 is The second scraping roller 26 is pushed into the pot 2 by the second compression roller 30 in the same manner as when it is scraped by the lower edge of the second scraping portion 27 to reach above the pot 2 and the floor soil 8 is supplied again. Therefore, there is an effect that it can be uniformly and surely supplied into the pot 2.
