[0015]

[Operation] Next, the operation will be described. As shown in FIG. 2, when the pot sheet 1 is supplied to the transfer table 10 while being fitted into the storage box 7 with the through hole 4 facing upward, the transfer protrusion 15 provided on the endless chain 14 causes the transfer projection 15 provided on the storage box 7. Engaging the rear wall of the transfer projection 1
5 moves the pot sheet 1 in synchronism with the seed feeding of the seed feeding device 28. Then, the pot sheet 1 reaches below the feeding part 21 of the soil feeding belt 20 of the floor soil supplying device 18, and is supplied with the floor soil 8 falling from above while being vibrated by the vibrating device 32.

The vibrating device 32 includes a rotating angle roller 34.
Corner portion 35 pushes the bottom surface of the storage box 7 upward, and the pushed bottom surface of the storage box 7 is separated from the corner portion 35 of the rotating angle roller 34 once by the action of inertia, and moves upward from the corner portion 35. Then, the pot sheet 1 vibrates up and down by repeating this. Note that, while the storage box 7 is being pushed up, the corner portion 35 may idle under the storage box 7, but another corner portion 35 is pushed up again. Therefore, since the floor soil 8 is supplied while giving vibration to the pot sheet 1, the floor soil 8 collapses due to the vibration before becoming a bridge at the through hole 4 of the pot 2 and prevents the occurrence of a bridge.

Further, a plurality of rotation angle rollers 34 are arranged side by side, and the corner portions 35 of the front and rear rotation angle rollers 34 are protruded higher than the upper surface of the guide roller 17, and the middle rotation angle roller 34 is positioned higher. Therefore, the pot sheet 1 gradually vibrates from before the feeding section 21 of the floor soil supplying device 18, the amplitude becomes maximum below the feeding section 21, and thereafter the amplitude becomes small. Therefore, since the soil is already vibrating before it enters the through hole 4 of the pot 2, the soil easily passes through the through hole 4, and when the soil next passes below the feeding portion 21, the amplitude also becomes maximum. , Not only to prevent the generation of bridge, but also to settle the particles of the soil that has passed through, so the floor soil 8 already in the pot 2 can be firmly tightened, and as a result a large amount of soil can be supplied, and it passes through the feeding section 21. After that, the vertical amplitude gradually decreases, so that the soil supplied into the pot 2 is prevented from scattering outside the through hole 4 without unnecessarily vibrating, and the soil tightness is improved. .

However, when the soil is dropped while being vibrated as described above, the floor soil 8 enters into most of the pot 2. For example, a large amount of mulch soil is contained in the fibrous soil or long wood chips. In some cases, bridges generated in the through holes 4 of some pots 2 cannot be prevented due to the nature of the floor soil 8 such as when the soil content is high, or when the soil has a high water content and a high viscosity. According to the present invention, since the bridge removing brush 45 that moves up and down by the up-and-down moving device 55 is provided, the tip of the up and down bridge removing brush 45 directly contacts the bridge, so that the bridge is completely eliminated.

That is, the cam wheel 57 is rotated by the rotation of the drive rotary shaft 56, and the cam wheel 57 drives the pin 59 to drive the drive rotary shaft 56.
Since the pin 59 and the brush rotating shaft 46 of the bridge removing brush 45 are connected by a connecting plate 58, the rotating motion of the pin 59 is converted into a linear reciprocating motion by the connecting plate 58, and the brush rotating shaft 46 is rotated. Therefore, the bridge removing brush 45 moves up and down, and when the tip of the up and down bridge removing brush 45 descends, the bridge removing brush 45 comes into contact with the bridge above the through hole 4 to collapse and eliminate it. A certain soil is pushed into the pot 2, and the vibration around the vibrating device 32 causes the soil around the through hole 4 to flow from the opened through hole 4.

Thus, the bridge is collapsed by the vibration of the vibrating device 32 and the vertical movement of the bridge removing brush 45, and a sufficient amount of the soil bed 2 is supplied into the pot 2.
In this case, the bridge removing brush 45 is not a fixed brush, but the mounting shaft 48 is rotated by the gear 53 to which the rotation is transmitted from the transfer table 10, and the rotation of the mounting shaft 48 is transmitted via the gear 51, the chain 52, and the gear 50. Since it is transmitted to the brush rotating shaft 46 and rotates, clogging of soil can be prevented and continuous work can be performed.

Since the bridge removing brush 45 is expected to push the soil above the through hole 4 into the pot 2, the tip of the brush 45 enters the pot 2 through the through hole 4, or When passing below the bridge removing brush 45, a space Y may be formed above the pot 2 due to a difference in the amount of the floor soil 8 contained in the pot 2 depending on the bridge generation timing. But,
When passing below the rotary leveling brush 26, the leveling action of the rotary leveling brush 26 causes excess soil to be gathered onto the pot 2 in which the space Y is located, which is the space Y in the pot 2.
Since it enters, all the pots 2 are filled with the ground soil 8.

That is, in the first place, the floor soil supply device 18 drops a considerable amount of the floor soil 8 and the first scraper 23
Means that a certain thickness of soil is left on the upper surface of the pot sheet 1. Further, the bridge removing brush 45 is configured as a cylindrical rotating brush, and its peripheral speed rotates in synchronization with the transfer speed of the pot sheet 1. Therefore, the bridge removing brush 45 and the pot 2 are relatively in a stopped state. In the same manner as described above, the bridge removing brush 45 does not give a resistance to the transfer of the pot sheet 1 and has an action of pushing from the top, but does not have a sweeping (leveling) action such as moving soil, Excess soil remains above the seat 1.

Further, even if the bridge removing brush 45 pushes the soil downward, since the brush 45 is formed to have a predetermined length, when the brush 45 is descended with respect to the through hole 4 having no bridge, the soil is already soiled. There is a bridge removal brush 4 on this soil.
When the tip of 5 touches, it bends due to elasticity and escapes. Similarly, since the space 79 between the pots 2 and 2 already has soil, the bridge removing brush 45 escapes and bends. Excess soil remains above the pot sheet 1.

Therefore, when the pot sheet 1 passes below the rotary leveling brush 26, excess soil is gathered on the pot 2 having the space Y by the leveling action of the rotary leveling brush 26. Because it enters the space Y of
All the pots 2 are filled with the bed soil 8. Further, the pressure roller 24 is also provided between the pressure roller 2 and the leveling brush 26 after passing below the bridge removing brush 45.
Due to the resistance when 4 presses the soil, the excess soil gathers and enters the space Y, and the next second scraper 25
The surplus soil when being leveled by the space Y enters the space Y, and the soil also enters the space Y even before the rotary leveling brush 26 (providing a resistance to the rotation of the pressing roller 24 works more effectively). In addition, the height of the rotary leveling brush 26 is set to a height at which excess soil can be removed in preparation for seeding by the seed feeding device 28, and the soil in the gaps between the pots 2 is not visible. It becomes soil.

The second embodiment of FIG. 8 also operates in the same manner,
When the arm 78 is turned on, the rotation motor 69 and the up / down motor 74 are energized, and the rotation motor 69 outputs 45 through the output gear 70, chain 71, gear 68, gear 65, rotary shaft 64, gear 66, The peripheral speed is rotated so as to be synchronized with the transfer speed of the pot sheet 1, the other vertical motor 74 rotates the pin 59 via the output gear 75 and the chain 76 cam gear 73, and the pin 59 connects the connecting plate. 58 is reciprocated, and the brush revolving shaft 46 of the bridge removing brush 45 is moved up and down by the reciprocating movement of the connecting plate 58. Then, when the tip of the up and down bridge removing brush 45 descends, the through hole 4
It touches the bridge above and collapses and dissolves. Since the pot sheet 1 is transferred in synchronism with the seed feeding of the seed feeding device 28, the seed feeding device 28
Although it is not shown in the drawing, the seed feeding device 28
The projection provided on the lower part of the pot descends and enters the pot 2 through the through hole 4 without stopping the moving pot 2 to form a dent in the upper part of the pot 2, and one or a desired number of grains can be formed in the dent. Sow the seeds.

In this case, the transfer of the pot sheet 1 is synchronized with the feeding of the seed of the seed feeding device 28, but as described above, in the present invention, the guide sheet 37 is provided above the rotation angle roller 34, and the pot sheet 1 is provided. Since the vibration is applied without changing the transfer speed of, the accurate seeding can be performed. In the embodiment, the transfer table 10 provided with the seed supply device 28 is provided with another transfer conveyor, in order to cope with the pot sheet 1 having a different number of pots 2 in the transfer direction. That is, the floor soil 8 is supplied by sending the pot sheet 1 without a gap, and the soil accumulated at the rear portion of the preceding pot sheet 1 is transferred to the front side of the succeeding pot sheet 1, whereby the pot 2 on the front side of the pot sheet 1 is fed. Although the amount of bed soil 8 to be supplied to the seed pot is secured to the seed pot, it is better to form a predetermined gap between the preceding pot sheet 1 and the following pot sheet 1 depending on the number of pots 2 in the seed feeding device 28. Since it can be accurately synchronized, therefore, another conveyor is used. Even in this case, however, if the transfer speed by the transfer protrusion 15 provided on the endless chain 14 changes, the transfer to the next conveyor cannot be performed properly. It is of course possible to supply soil and seeds on the same conveyor.

The transfer plate 15 provided on the rear side of the transfer protrusion 15 shown in FIG. 4 is a transfer plate 44, which is located between the rear end of the preceding storage box 7 and the front end of the subsequent storage box 7. A transfer protrusion 15 is formed by eliminating a gap generated between the transfer protrusions 15 and is formed of an elastic flat plate.
Removably attached to. Although the shape of the pot 2 is not a requirement, when viewed from the side, the pot 2 is formed so that the upper part is narrower and the lower part has a larger space, and the pot 2 is formed in a rectangular shape, a polygonal shape, a circular shape, or the like. Incidentally, the pot 2 may be opened at the top to form a through hole 4,
The pot sheet 1 may be made of any material, such as a material that rots when placed in soil such as paper, or a synthetic resin. Also, the transplanting method differs depending on the material shape of the pot sheet 1, and the seedlings are taken out of the pot 2 by an appropriate means.
Sometimes this is transplanted to the field or pot, for example,
When the pot 2 is formed so that the upper side and the lower side are substantially the same space when viewed from the side, it is possible to push up from the bottom and remove the seedling from the pot 2 to plant it in the field, and the transplanting method is not a requirement. Absent.

The transfer means of the transfer table 10 is composed of the transfer protrusions 15 provided on the endless chain 14 so as to move in synchronization with the seed feeding of the seed feeding device 28.
When the seed supply device 28 is not provided on the transfer table 10, the configuration such as a transfer roll or a transfer belt is not a requirement.

[0029]

[Effect] Therefore, according to the present invention, the pot sheet 1 formed by vertically and horizontally connecting the lower portion of the pot 2 having the through hole 4 on the upper surface,
In a device having a transfer table 10 for laterally transferring the pot sheet 1 with the upper surface 3 facing upward, and a floor soil supply device 18 provided above the transfer table 10 and capable of supplying floor soil to the pot sheet 1.

Above the vibrating device 32, a pair of left and right rotating members is provided. Attached to the tip of arm 47,
The bridge removing brush 4 which moves up and down by the up-and-down moving device 55.
Since it is a pot sheet soil supplying device provided with 5, the tip of the up and down bridge removing brush 45 directly contacts the bridge to completely eliminate the bridge, and the vibration by the vibrating device 32 releases it from the bridge. The soil around the through hole 4 can be made to flow in through the through hole 4, and the floor soil 8 can be reliably supplied into the pot 2. Also,
According to the present invention, the vibrating device 32 includes a rotating shaft 33 in the left-right direction.
A plurality of rotation angle rollers 34 each having a polygonal cross section fixed to the above are arranged side by side in the transport direction of the pot sheet 1, and the bridge removing brush 45 has a cylindrical rotation brush configuration. Since the pot sheet soil supplying device is configured to be driven and rotated so that the peripheral speed is synchronized with the transfer speed of the pot sheet 1, not only can it be implemented with a simple structure, but the bridge removing brush 45 can be of a cylindrical shape. Since it has a rotating brush configuration, soil can be prevented from clogging between the brushes and continuous work can be performed. Also,
Since the peripheral speed of the brush 45 is driven and rotated in synchronization with the transfer speed of the pot sheet 1, the brush 45 is rotated.
Has the effect of pushing the soil into the pot 2 from above,
There is no sweeping (leveling) action like moving the soil, and excess soil can be left above the pot sheet 1, and this excess soil will enter the pot 2 due to vibration, so the floor soil can be reliably 8 can be supplied. The present invention also relates to the vertical movement device 55.
Is a pot sheet soil supply device in which a cam ring is provided on the transfer table 10 side, and the cam ring and the brush rotating shaft 46 of the bridge removing brush 45 are connected by a connecting plate 58 whose length is freely changeable. Therefore, the mounting structure of the bridge removing brush 45 can be simplified, the vertical width and height of the bridge removing brush 45 can be adjusted, and the bridge removing brush 45 can be used in correspondence with soil and pot sheets of various properties. Further, the present invention provides a pot sheet soil supply device, which is provided with a rotating leveling brush 26 capable of leveling the upper surface of the pot sheet 1 and removing excess soil on the lower side of the bridge removing brush 45. Therefore, the bridge removing brush 45 is used for the reason that the amount of the floor soil 8 contained in the pot 2 varies depending on the bridge generation time.
When passing below the rotary leveling brush 26, excess soil may be generated by the leveling action of the rotary leveling brush 26 even if a space Y is formed above the inside of the pot 2 when passing below the rotary leveling brush 26. Since it is gathered on the pot 2 having Y and enters the space Y in the pot 2, the effect is obtained that all the pots 2 are filled with the soil 8.
