Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for planting seedlings used in transplanters and the like.

[0002]

2. Description of the Related Art A seedling planting device of a transplanting machine is provided with a planting body formed in a cup shape having a tapered lower end and capable of holding soild seedlings therein. The seedling held inside by forming a perforated hole and opening the lower side is planted in the planted hole.
It is well known from Japanese Patent No. 4218 and the like.

[0003]

The seedlings of the crop planted by the transplanter include only the soil portion of the seedlings in the planting holes formed by the planting bodies, such as vegetable seedlings such as cabbage and Chinese cabbage. The leaves are protected from frost damage by placing not only the soil but also the leaves in the planting holes, such as those that are buried and the leaves are planted in a state where the leaves are exposed from the ridges, or seedlings such as tobacco. There is a plant that is planted in a state, and the above-mentioned conventional planting plant is for planting a plant such as cabbage and is not suitable for planting a plant such as tobacco.

That is, seedlings such as tobacco or the like need to form a large-diameter deep planting hole because the leaves are also contained in the planting hole, but conventional plantings only form a small-diameter shallow planting hole. If the outside diameter of the planting body is made large and deeply pierced into the ridge to form a large diameter and deep planting hole, seedlings fall down in the planting body. In addition to the fear, the resistance at the time of piercing the ridge becomes large, and a load is imposed on the driving mechanism of the plant.

[0005] Further, simply forming a planting hole by piercing a planting body into a ridge easily collapses the side surface of the planting hole. When the collapsed soil covers the leaves in the planting hole, the leaves are damaged. In addition to the cause of withering and the like, there is a problem that the vigor and viability of the seedlings are inhibited. In particular, in the case of crops such as tobacco, the leaves become products, so the problem of landslides in the planting holes is an important problem that affects the product value.

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a seedling planting method in which soiled seedlings, not only soil portions but also seedlings, are planted in planting holes formed in ridges. It is intended to provide a device.

The present invention employs the following technical means to achieve the above object. That is,
The seedling planting apparatus according to the present invention is a planting body for forming a planting hole H by piercing the ridge R and opening the lower side to plant the soiled seedling N held therein in the planting hole H. In the seedling planting apparatus provided with the lower cylinder 1, the lower part 3 of the lower part 3 is configured so that the lower part can be freely opened and closed so as to discharge the seedling N into the planting hole H. An upper cylinder 6 is provided on the upper side, and is configured to be expandable and contractable so as to push and expand the upper side of the planting hole H in conjunction with the opening / closing operation of the lower cylinder 3.

In the seedling planting apparatus according to the present invention, the planting hole H is formed by piercing the ridge R, and the soiled seedling N held inside by opening the lower side is inserted into the planting hole H. In a seedling planting apparatus provided with a plant 1 to be planted, the plant 1 is
The lower components 2, 2 are constituted by a pair of lower components 2, 2 in a horizontal direction, and the lower components 2, 2 are opened and closed by rotating the lower components 2, 2 around an axis 4 provided on the upper side of the lower components 2, 2. A lower cylinder 3 that is free and provided above the lower cylinder 3,
The upper components 5, 5 are formed in pairs in the horizontal direction, and the upper components 5, 5 are turned around the shaft 4 provided on the lower side of the upper components 5, 5, so that the upper portion is turned. It is characterized by comprising an upper cylinder 6 which can be freely expanded and contracted in the horizontal direction, and an interlocking means 7 which expands and contracts the upper cylinder 6 in conjunction with the opening and closing operation of the lower cylinder 3.

According to the seedling planting apparatus described above, the lower tube 3 and the upper tube 6 constituting the planted body 1 are pierced into the ridges R to form planting holes H, and the lower tube 3 is opened to open the inside. Is released into the planting hole H. At this time, since the upper cylinder 6 expands and contracts in conjunction with the opening / closing operation of the lower cylinder 3, the upper cylinder 6 also expands by opening the lower cylinder 3, and pushes and expands the upper side of the planting hole H, thereby opening and closing the planting hole. Compact the sides.

[0010] By such an action, the seedling N
As described above, not only the soil portion but also the leaf portion can be accommodated in the planting hole H, and the leaf portion can be suitably accommodated in the upper portion of the planting hole expanded by the upper cylinder 6. Since the side surface of the planting hole H is compacted, it is possible to prevent the soil from collapsing and covering the leaves.

Further, when piercing the ridge R, the lower tube 3 and the upper tube 6 can be closed, so that the piercing resistance is reduced, and the load on the driving mechanism of the plant 1 is also reduced. The interlocking means 7 is constituted by a connecting member 8 for connecting the lower structural member 2 and the upper structural member 5 facing each other obliquely with the shaft 4 interposed therebetween, or by interposing the horizontal shaft 4 therebetween. It is preferable that the lower component 2 and the upper component 5 that face each other in the oblique direction be integrally formed, whereby the upper cylinder 6 and the lower cylinder 3 can be linked with a simple structure. .

Further, the upper tube 6 of the planting body 1 according to the present invention is characterized in that it is formed in a shape that expands in the direction of expansion and contraction toward the upper side.
And the upper side surface of the planting hole H can be formed on a gentle slope so that the landslide can be reliably prevented.

Is supported via a swinging link mechanism 31 and moves while drawing a substantially long elliptical locus up and down. The seedling N is supplied at the upper end of the locus, and the planting body 1 is moved at the lower end of the locus. The ridge R is projected.

As shown in FIGS. 1 and 2, the planting body 1 is configured to form a planting hole H by piercing a ridge R, and the planting body 1 according to the present invention is made of tobacco. Like the seedlings, etc., the plant can be suitably used for crops in which not only the soil portion N1 of the soiled seedling N but also the leaf portion N2 are housed in the planting hole H. The planting body 1 includes a lower cylinder 3 formed in a cup shape (bottomed cylindrical shape) having a tapered lower end.
And an upper cylinder 6 provided on the upper side of the lower cylinder 3 and penetrating vertically. The lower cylinder 3 is configured to abut a pair of front and rear lower components 2. , And each of the lower structural members 2 is supported by a left-right shaft 4 provided on an upper portion so as to be swingable back and forth.

Since the upper side surface of the planting hole H is in a compacted state, it is possible to prevent the soil from collapsing and covering the leaf portion N2.

The planted body 1 is closed because the lower tube 3 and the upper tube 6 are closed when receiving the seedling N from the seedling supply device 25 and when piercing the ridge R. The fall of the seedling N in the inside can be prevented, the piercing resistance is reduced, and the load on the swing link mechanism 31 and the like can be reduced. Note that, as the interlocking means 7, the lower component 2 and the upper component 5 that are diagonally opposed to each other across the shaft 4 without the connecting member 8 are integrally formed,
It is also possible to configure by connecting a continuous portion of the lower component member 2 and the upper component member 5 formed integrally with each other with the shaft 4.

As shown in FIG. 5, the rear end of the movable frame 28 supporting the seedling plant 24 and the fixed frame 2
7 is a damper device 32 capable of variably setting the internal pressure.
When the planting body 1 is pierced by the reaction force from the ridge R when the planting body 1 pierces the ridge R to form the planting hole H, the damper device 32 The rapid movement of the movable frame 28 due to the above can be absorbed.

Further, the transplanter 10 according to the present embodiment is provided with adjusting means 33 for variably adjusting the strength of the damper device 32 according to the hardness of the ridge R. This adjusting means 3
Reference numeral 3 denotes a detecting means 34 such as a potentiometer which is provided on a bearing at the tip of the movable frame 28 and detects the amount of vertical swing of the movable frame 28;
And a control means 35 for calculating the swing acceleration of the movable frame 28 based on the detected value of the movable frame 28 and the swing speed of the movable frame 28 and controlling the strength of the damper device 32 from the calculated value.

When the plant body 1 is pierced into the ridge R, if the ridge R is hard, the above-mentioned reaction force increases and the plant body 1 jumps up rapidly, the swinging acceleration of the movable frame 28 increases, and the seedling N There is a risk that the planting depth of the plant will be shallow,
In such a case, the strength of the damper device 32 is strongly adjusted by the adjusting means 33 to suppress the jump. Further, when the ridge R is soft, the bouncing of the planted body 1 is set small by setting the strength of the damper device 32 to be small, since the spring of the planted body 1 is small and the swing acceleration of the movable frame 28 is small. The ridge R is prevented from being deformed.
