Description

The present invention relates to a paper pot sowing apparatus.

(Prior Art) Japanese Patent Application Laid-Open No. 61-141806 discloses a stand formed by forming a through hole at the center of the bottom wall of a pot made of a water-soluble paper material, and standing upward around the bottom wall. A paper pot provided with a wall, the upper edge of each standing wall being connected, a storage box in which the paper pot is fitted, a horizontal transfer table for transferring the storage box, and a soil covering device above the horizontal transfer table In a seeding device for a paper pot comprising a seed rice supply device and a floor soil supply device, a paper pot seeding device provided with a pressing device for pressing the paper pot is provided at a position below a supply unit of the covering soil supply device. ing.

That is, since the paper pot b itself is very light, and the bottom d of the pot c is formed not flat but distorted, the paper pot b is fitted into the storage box a as shown in FIG. Then, the bottom d of the paper pot b contacts only a part, and the other part is slightly lifted up from the bottom e of the storage box a and stored. When soil was supplied to each pot c in this state, there was a defect that soil leaked from the through hole f formed in the bottom d of the pot c.

Therefore, a pressing device is provided at a position below the supply section of the soil covering supply device, and the bottom d of the paper pot b is pressed against the bottom e of the storage box a.

(Problems to be Solved by the Invention) However, in the known example, since the pressing device is provided only at a position below the supply unit of the covering material supply device, the paper pot b rises during the transfer and each pot c There was a problem that the soil cover and seeds in the inside leaked from the through-hole f.

In addition, the paper pot that supplied the covering soil, the seed paddy, and the floor soil was inverted and fitted into the seedling raising box, and the soil was supplied between the pots. However, a soil supply device for supplying the soil was provided on the transfer table. .

It is provided on the upper surface of each of the 25 to protrude inward. Reference numeral 71 denotes a feed belt of the soil covering supply device 15, reference numeral 72 denotes a floor soil pressure reduction roller, and reference numeral 73 denotes an upward moving device of the pressure reduction roller 51, which is used to supply the soil.

(Operation) Next, the operation will be described.

When the storage box 3 containing the paper pots 2 is placed in the supply section 12 of the horizontal transfer table 1 in a superimposed manner and the motor is energized, only the lowermost storage box 3 out of the stacked storage boxes 3 is sequentially fed out. Crushing roller 13 before reaching the soil covering device 15
As a result, the paper pot 2 is crushed with a considerable pressure, and the bottom wall 6 of the paper pot 2 comes into close contact with the bottom plate 14 of the storage box 3.

Since the first pressing device 16 is provided below the supply unit of the covering device 15, the first pressing device 16 is provided below the supply unit of the covering device 15.
The rear end portion of the paper pot pressing rod 19 of the pressing device 16 is lifted and slid under the rear end, and the soil is supplied while being pressed by the paper pot pressing rod 19.

Therefore, since the bottom wall 6 of the pot 5 is in close contact with the inside of the storage box 3, the soil does not leak from the through hole 7.

In this state, it passes below the seed paddy supply device 32, receives the supply of the seed paddy from the seed paddy supply device 32, and is transferred to the floor soil supply unit 33.

During this transfer, the paper pot 2 rises and the soil cover and the seed paddy may leak from the through-hole 7 of the pot 5. Since the pressing device 34 is provided, the second pressing device
While pressing the paper pot 2 into the storage box 3 by 34, the paper pot 2 is transferred to the floor soil supply device 33.

The third pressing device 54 is provided below the feeding belt 53 of the floor soil supply device 33, and the pressure-reducing roller 51 is provided on the front side of the third pressing device 54. It is pressed with a considerable pressure into the storage box 3 and immediately sinks below the third pressing device 54. Accordingly, the paper pot 2 is supplied with the floor soil while being pressed by the third pressing device 54.

The second pressing device 34 is configured so that the paper pot pressing member 35 can be attached to and detached from the supporting plate 36 without removing the supporting plate 36 from the horizontal transfer table 1. Since it has approximately the same length as the seedling raising box 49 in which the pot 2 is fitted, when the paper pot pressing body 35 of the second pressing device 34 is removed, the seedling feeding device 32 and the floor soil feeding device 33 Can form a long space that can supply the nursery box 49.

Therefore, between the seed rice supply device 32 and the floor soil supply device 33 from which the paper pot pressing body 35 has been removed, a seed soil supply unit 50 can be formed. When the box 49 is supplied, the floor clay can be supplied between the bottom walls 6 of the pots 5 by the floor soil supply device 33.

(Effect) According to the present invention, a through hole 7 is formed at the center of the bottom wall 6 of the pot 5 made of a water-soluble paper material, and the upright walls 8 are provided around the bottom wall 6 to rise upward. 8, a paper pot 2 having an upper edge coupled thereto, a storage box 3 into which the paper pot 2 is fitted, a horizontal transfer table 1 for transferring the storage box 3, and a cover feed at a position above the horizontal transfer table 1. In a paper pot sowing apparatus comprising an apparatus 15, a seed paddy supply apparatus 32, and a bed soil supply apparatus 33, the seed paddy supply apparatus 32
The paper pot 2, which tends to float, is moved so that the central through hole 7 of the bottom wall 6 of the pot 5 moves while being in close contact with the bottom surface of the storage box 3 while reaching the floor soil supply device 33 through Since the paper pot sowing device is provided with the pressing devices 16, 34, and 54 for pressing into the storage box 3, the paper pot 2 is pressed from above even during the transfer of the storage box 3, It is possible to prevent the cover soil and the seed rice from leaking from the hole 7.

Further, a press device 34 that presses the paper pot 2 that tends to float into the storage box 3 is provided in the wide space between the seed pad supply device 32 and the floor soil supply device 33, while forming a wide space between the seed pad supply device 32 and the floor soil supply device 33. The pressing device 34 is configured to be detachable, and when the pressing device 34 is removed, it is a seeding device for a paper pot so as to become the seed supply unit 50 of the seedling raising box 49,
A seed supply 50 can be formed between the seed supply 32 and the floor supply 33 from which the pressing device 34 has been removed, and a seedling box 49 fitted with the paper pot 2 is supplied from the seed supply 50. Then
The floor soil supply device 33 has an effect that the earth can be supplied between the bottom walls 6 of the pots 5.
