DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transporting potted seedlings and a transplanter for potted seedlings, which are suitable for planting potted seedlings such as chrysanthemums, cabbage, broccoli and the like, which have expanded leaves such as vegetables.

[0002]

2. Description of the Related Art As a transplanter for pot seedlings, a seedling mounting table, a seedling receiving table, a lateral transport belt, a descending belt, a planting device, and the like are installed on a running machine and are pushed out of a pot seedling box on the seedling mounting table. One row of potted seedlings is received by a seedling receiving stand, and the seedling receiving stand is turned sideways on a pair of horizontal conveying belts which are horizontally stretched on the machine body and rotated in opposite directions while the potted seedlings are turned over. A pot seedling fed from the edge of the conveyor belt is horizontally held by a pair of descending belts rotating in opposite directions, transported downward, and supplied to a planting device. (For example, see Japanese Utility Model Publication No. 1-2977 and Japanese Utility Model Publication No. 1-29778).

[0003] First, this will be described in detail with reference to FIG. 4. In the above-mentioned pot seedling transplanter, a flexible pot seedling box 1 having a large number of pot seedling rooms connected in series is provided inside a seedling mounting table 2. The rod 3 is intermittently fed one row at a time, and a pushing rod 3 provided at a predetermined position behind the seedling mounting table 2 projects from a bottom surface into a row of pot seedling chambers 1a in a horizontal row of the pot seedling box 1 to move the pot seedlings forward. At the same time, and push the root portion into the seedling receiving groove 4a of the seedling receiving stand 4 provided at the front (shown by a solid line in FIG. 4). continue,
The seedling receiving table 4 receiving the pot seedlings rotates downward while turning the pot seedlings in the opposite direction (indicated by phantom lines in FIG. 4),
At this time, the seedling receiving groove 4a passes through the position of the projecting member 6 with the root portion of the pot seedling first. As a result, the pot seedling is pushed out from the seedling receiving groove 4a, and the spring-out member 6 is lowered (indicated by an arrow A) at the same time when the pot seedling is removed from the seedling receiving groove 4a.
Rotate quickly to drop the pot seedlings onto the lower conveyor belt 5. The reason for forcibly dropping the pot seedlings without leaving them to fall naturally is to supply the pot seedlings to a predetermined position of the moving horizontal transport belt quickly and reliably.

FIG. 5 shows an arrangement in which a descending belt and a planting device suitable for planting vegetables and the like are arranged at the edge of the horizontal transport belt 5. As shown here, the horizontal transport belt 5 is composed of a pair of endless belts rotating in opposite directions, and the pot seedling (only one is shown for simplicity) supplied on the horizontal transport belt 5 is shown in FIG. Aligned vertically in the transport direction, transported horizontally on the horizontal transport belt 5 toward the edge, and when it reached the edge, dropped into the seedling receiver 7, and subsequently fed above the seedling receiver 7. The claw 8 descends, and the pot seedling is sent downward from the swingable seedling receiver 7. The fed seedlings are sandwiched between a pair of endless descent belts 9 rotating in opposite directions, descend while maintaining a horizontal posture, and supplied to the planting device 10 at the lower end of the descent belt 9. Planting device 10
Is composed of a pair of disks that are arranged opposite to each other at a predetermined angle and rotate in the same direction, and the pot seedlings sandwiched between the opposite surfaces are rotated downward with rotation, and formed on the ground surface by the groove cutting blade 11. Into the groove. Implantation is immediately performed on the pot seedling by an unillustrated mulching wheel, and at the same time, the holding by the planting device 10 is released, and the transplanting is completed.

[0005]

By the way, in the conventional transplanter for pot seedlings described above, the entire pot seedling is transported by the horizontal transport belt 5.
The belt width of the horizontal transport belt 5 is set so as to ride on the top, and if the leaves are elongated and soft like a green onion seedling, the entire seedling is supported on the horizontal transport belt 5 and is perpendicular to the transport direction. Is transported while maintaining the proper orientation. However, when planting potted seedlings such as chrysanthemums, cabbage, and broccoli seedlings that have developed leaves, the center of gravity is high and unstable because the seedlings are supported on the horizontal transport belt 5 at the roots and the developing leaves. ,
As shown in FIG. 2, depending on the shape of the leaf portion, it rolls around the root pot to a stable direction (solid line → virtual line), is conveyed in a posture inclined with respect to the conveyance direction, and has a timing to supply the pot seedling to the descending belt. It shifts or the planting posture becomes worse.

[0006] In the case of a pot seedling in which the leaves are unfolded, the position of the leaves on the horizontal transport belt 5 is higher than that of leek or the like.
As shown in FIG. 3, when the seedling receiving tray 4 receiving the next pot seedling rotates downward, or after the seedling receiving tray 4 drops the pot seedling onto the horizontal transport belt 5, it rotates upward again. At this time, the tip of the seedling receiving table 4 (showing the rotation locus by a virtual line) catches the leaves of the pot seedlings on the horizontal transport belt 5 to cause the displacement of the pot seedlings, and the displaced pot seedlings are transferred to the planting device. Supplied,
In some cases, the planting posture was deteriorated, for example, when the plants were planted shallowly, deeply, or inclined.

[0007] The present invention has been made in view of the above-mentioned problems of the prior art. Even when a pot seedling such as a chrysanthemum, cabbage, or broccoli seedling is planted, the pot seedling is transferred to a horizontal conveyor belt. An object of the present invention is to provide a pot seedling transfer method and a transplanter for pot seedlings that can be transferred in a state where they are properly aligned perpendicularly to the transfer direction, and can prevent poor planting such as deterioration in planting posture.

[0008]

According to the present invention, there is provided a method for transporting pot seedlings, wherein a seedling receiving stand for receiving a row of potted seedlings pushed out of a pot seedling box on a seedling mounting table is horizontally supported downward.
Up and down on the endless horizontal transport belt 15
And, constructed as described above seedlings bearers while reversing the seedlings when rotated downward is supplied to the endless horizontal conveyor belt, to supply the seedlings fed from the edge to the planting device of the lower When transplanting a pot seedling having a developing leaf portion using the transplanted pot seedling transplanter, the root seedling and the stem portion of the pot seedling ride on the endless horizontal transport belt, and the developing leaf portion protrudes backward. It is characterized in that it is placed as follows.
Further, in the transplanter for pot seedling according to the present invention, in the transplanter for pot seedling configured as described above, the root width and the stem portion of the pot seedling ride the belt width of the endless horizontal transport belt, and the deployed leaf portion. Is set to the width that protrudes backward,
Preferably, a windproof cover is provided behind the horizontal transport belt along the horizontal transport belt.

[0009]

In the above-described pot seedling transplanter, the width of the horizontal transport belt is set to be narrower than that of the conventional pot seedling transplanter, and the root pot and stem portions of the pot seedling are placed on the horizontal transport belt. It is supported, and the deployed leaf portion is placed so as to protrude behind the horizontal transport belt, so that the position of the leaf portion is lower than before, the pot seedlings are less likely to roll on the horizontal transport belt, and the seedling receiving stand holds the leaves. No more snagging.

[0010] On the other hand, since the width of the lateral transport belt is narrow and the developed leaves protrude, when a strong wind blows, there is a greater possibility that the pot seedlings will be lifted up from the lateral transport belt or cause displacement. More. In order to cope with this, a windproof cover is provided at the rear position of the horizontal transport belt to protect the developing leaf portion of the pot seedling from the wind, so that the floating of the pot seedling and displacement thereof are prevented.

[0011]

An embodiment of the present invention will be described below with reference to FIG. The structure of the transplanter for pot seedlings of this embodiment is the same as that of the conventional transplanter for pot seedlings shown in FIGS. 4 and 5 except that the width of the horizontal transport belt 15 is reduced. The pot seedling that has fallen from the seedling receiving stand 4 has its root pot and stem portions supported on the horizontal transport belt 15, and the leaves are transported horizontally with almost all of the leaves protruding rearward.
5 is supplied to the descending belt from the edge, and is supplied to the planting device from the descending belt and is planted on the ground.

The pot seedling is supported on a horizontal conveyor belt 15 at a root pot portion and a stem portion.
Since it protrudes rearward, it does not roll further due to the shape of the developing leaf portion, and the posture aligned vertically to the transport direction is maintained. In addition, since the protruding leaves are lowered and the position is lowered, the leaves are prevented from being caught on the seedling receiving stand 4 and the pot seedlings are prevented from being displaced. Therefore, the pot seedlings can be transported on the horizontal transport belt 15 in a state of being properly aligned perpendicularly to the transport direction, and poor planting such as deterioration of the planting posture can be prevented.

A windbreak cover 16 is provided horizontally behind the horizontal transport belt 15 along its length. In this embodiment, the windbreak cover 16 is a frame composed of a horizontal portion 16a and a vertical portion 16b for preventing wind from below, but any shape may be used as long as the developed leaf portion of the pot seedling can be protected from strong wind. May be something.

[0014]

According to the present invention, a pot seedling having a developed leaf portion can be transported on the horizontal transport belt 15 in a state where it is properly aligned perpendicularly to the transport direction. Can be prevented.
