Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a seedling planting nail for sandwiching a seedling itself and planting it in a field in a transplanter for seedlings such as straw grass and rice.

[Conventional technology]

An example of the above-mentioned nails with seedlings is disclosed in Japanese Utility Model Laid-Open No. 63-95423. That is, a pair of vertically fixed left and right fixed type first claws ((3) in the above publication), and a seedling pushing section (see the above publication in which the lower side between the first claws is slidably driven along the first claws). (5)) and the structure comprised.

With the above structure, when the tip of the first nail passes through the seedling take-out port of the seedling stand, the vicinity of the root of the stem of the seedling is left and right.
It is sandwiched between the nails, and the root portion of the seedling is held between the left and right first nails and the seedling extruding portion (see FIGS. 3 and 1 of the publication). Then, when the roots of the seedlings enter the field, the seedling extruding part is slid and driven, and the seedlings are extruded into the field and planted (see FIG. 1 of the publication).

[Problems to be solved by the device]

In the above-mentioned nails with planted seedlings, seedlings are held mainly by sandwiching the stem portion of the seedlings between the fixed first nails.

Therefore, depending on the type of seedling to be planted, such as straw grass, the left and right first nails may be too wide and the stem portion of the seedling may easily come off from between the first nails. In such a situation,
After the first nail has passed through the seedling take-out port and the seedling is sandwiched, the stem portion of the seedling may come out between the first nails before entering the field, and the seedling may not be planted correctly in the field.

The object of the present invention is to obtain a structure in which the seedlings can be securely held by the nails with seedlings.

[Means for solving the problem]

The feature of the present invention resides in that the above-mentioned nail with a seedling is constructed as follows. That is, a pair of vertically long left and right first claws and a seedling pushing-out portion that is slidably driven between the first claws along the first claws are provided, and a vertically long second claw is provided between the left and right first claws. The left and right first
The urging means is arranged along the nail and presses the second nail against the upper surface of the seedling pushing-out portion.

[Action]

When configured as described above, for example, as shown in FIGS. 1, 2, and 3, the first and second nails (15), (1
When 6) passes through the seedling take-out port, the stem (A ₁ ) of the seedling (A) to be taken out is separated into right and left, and the right first claw (1
5) and the second claw (16) and between the left first claw (15) and the second claw (16) to be sandwiched and the root part (A ₂ ) of the seedling (A) is extruded. Located at the part (18), the seedlings (A) are taken out by the seedling planting claws (3).

As described above, two locations on both inner surfaces of the left and right first claws (15),
And 2 places on the left and right sides of the second claw (16), for a total of 4 places
The stem portion (A ₁ ) of the seedling (A) will be securely held.

On the contrary, the seedling extrusion part (18) projects in the field and the seedling (A)
When the planting is performed, since the second claw (16) is pressed against the upper surface of the seedling pushing part (18), the seedling pushing part (18) is driven to project in this pressed state. Therefore, the stem portion (A ₁ ) of the seedling (A) located near both the left and right sides of the second nail (16)
The seedlings are extruded by the seedling extruding part (18) without leaving any residue.

[Effect of device]

As described above, the stem portion of the seedling that was conventionally sandwiched between two locations on both inner surfaces of the left and right first nails can now be securely sandwiched at four locations. The number of seedlings falling out was reduced, and planting defects could be reduced.

In addition, when the seedlings are firmly sandwiched in this way, there arises a problem that the seedlings are hard to come off from the seedling-planting nails at the time of planting, but in the present invention, this problem is caused by pressing the second nail on the upper surface of the seedling pushing part. The occurrence of is suppressed.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 7 shows the entire side surface of the transplanter for strawberries, in which the seedling planting claws (3) are attached to the crank arm (2) which is rotationally driven at the rear of the planting mission case (1). There is. Then, a seedling stand (8) that is reciprocally slidably driven is provided along a guide rail (7) fixed to the upper surface of the planted mission case (1), and a float is provided below the planted mission case (1). (13) is supported to construct a transplanter for strawberries.

Next, the seedling stand (8) will be described. 4th, 5th, 6th
As shown in the figure, there are provided a first partition plate (4) that divides a portion corresponding to each planting strip and a second partition plate (5) that divides the center of the portion corresponding to each planting strip into right and left. Then, after the seedlings (A) are grown in a mat shape, the seedlings (A) are once divided into individual strains, and these are collected again and placed between the left and right first partition plates (4).

At the bottom of the seedling stand (8), when the seedling stand (8) reaches the stroke end of the reciprocating slide, the seedling (A) on the seedling stand (8) is placed on the lower guide rail (7) side. A belt type vertical feed mechanism (11) is provided for feeding to. Then, in the part of the seedling placing base (8) side extending from the end of the vertical feeding mechanism (11) to the guide rail (7), the seedling placing surface (about the same position and height as the feeding surface of the vertical feeding mechanism (11) ( 6) is provided, and a laterally long concave portion (9) is formed by the edge of the seedling placing surface (6) on the seedling take-out port (12) side and the guide rail (7).

Then, as shown in FIGS. 4, 5, and 6, the seedling surface (6)
A plurality of rooting plates (10) for dividing the root portion of the seedling (A) into the number of stocks taken out by the seedling planting nails (3) are fixed to the end portion on the seedling take-out port (12) side. The rooting plates (10) are made of a thin plate, arranged at the same pitch as the lateral width of the seedling take-out ports (12), and are located in the horizontally long recesses (9).

With the above structure, the seedling stand (8) reaches the horizontal feed stalk end, and the seedling (A) on the seedling stand (8) is moved to the seedling take-out port (12) side by the vertical feed mechanism (11). When the stroke is fed, the seedling (A) near the end of the vertical feed mechanism (11) is fed from the end of the vertical feed mechanism (11) onto the seedling placement surface (6). Further, along with the feeding action of the vertical feeding mechanism (11), the seedlings (A) in the row near the terminal end on the seedling placing surface (6) are fed into the recesses (9).

In this case, in the seedlings (A) in the row near the end on the seedling surface (6), the roots of the seedlings fall into the recesses (9) from the edge of the seedling surface (6) to some extent, and the seedlings in this row ( In A), the roots of adjacent seedlings (A) are also divided to some extent by the width of the seedling take-out port (12) (corresponding to one stock taken out) by each rooting plate (10).

Next, the seedling planting nail (3) will be described. First, second,
As shown in Figs. 3 and 7, the first claw (15) with the tip slightly sharpened by bending a plate material into an L-shaped cross section is provided on the upper left end of the main body (14) of the nail (3) with seedlings. The pair is fixed in parallel at a predetermined interval. On the upper side of the first claw (15), a vertically elongated second claw (16) made of a leaf spring and having a slightly sharpened tip is positioned between the left and right first claws (15) in plan view (second It is fixed so as to be located slightly above the first claw (15) in a side view (see FIG. 1).

The main body (14) is provided with a support shaft (17) slidably driven by a cam mechanism (not shown) inside the main body (14), and the seedling extruding section (18) is fixed to the tip of the support shaft (17). ing. The seedling extruding portion (18) has a solid block shape and is in contact with the inner surfaces of the left and right first claws (15) and the lower surfaces of the second claws (16) as shown in FIG. Particularly, in the second claw (16), the upper surface of the second claw (16) is pressed against the seedling pushing-out part (18) by the elastic force of the second claw (16) itself.

With the above structure, the seedling stand (8) is intermittently sent along the guide rail (7) by the set stroke (equivalent to the pitch of the rooting plate (10) and the lateral width of the seedling take-out port (12)). While going, the first and second claws (15), (16) of the claws (3) with seedlings are placed between the pair of rooting plates (10) while the seedling stand (8) is stopped. Pass through the seedling take-out port (12) of the street guide rail (7).

At this time, as shown in FIG. 3, a pair of rooting plates (10)
The stem part (A ₁ ) of _one seedling (A) between
The first claw (15) and the second claw (16) on the right side and the first claw (15) and the second claw (16) on the left side are inserted and pinched, and the root part of the seedling (A) ( A ₂ ) is located at the seedling extruding part (18) and the seedling (A) is taken out by the seedling planting claw (3).

In addition, the root portion (A ₂ ) of one seedling (A) taken out by the seedling-planting nail (3) and the seedling (A) remaining on the seedling stand (8)
(The seedling (A) placed on the seedling placing surface (6), and the root portion (A ₂ ) of the seedling (A) between the adjacent rooting plates (10),
When the seedlings (3) are taken out by the seedlings with the nails (3), the seeding surface (6) and the roots can be separated by dividing the seedlings by the rooting plate (10) and the seedling surface (6). at divided plate edge of (10), the root portion (a ₂₎ of the seedling root of (a) (a ₂₎ and remains in the seedling stage (8) seedlings (a) to be taken out and it than is quickly divided The phenomenon that the roots (A ₂ ) of the seedlings (A) remaining on the seedling stand (8) are dragged together is reduced.

Then, when the tips of the first and second claws (15), (16) project into the field (G), the support shaft (17) and the seedling extruding section (18) are slid to the projecting side. As a result, the root portion (A ₂ ) of the seedling (A) is in the field (G) while the stem portion (A ₁ ) of the seedling (A) is pulled out from between the first and second nails (15) and (16). It is pushed out and planted.

In the structure shown in FIGS. 1, 2, and 3 above, the second claw (1
6) is made into a flat plate and is brought into substantially flat surface contact with the upper surface of the seedling extruding part (18), and the stem portion (A) of the seedling (A) is provided between the upper surface of the seedling extruding part (18) and the second claw (16). A ₁ ) makes it difficult to get in.

This is because when the second claw (16) is formed into a round bar shape instead of a flat plate shape, in the front view of FIG. 3, due to the upper surface of the seedling extruding part (18) and the side surface of the round bar-shaped second claw (16). Since a sharp-angled concave portion is formed, depending on the type of seedling (A), the stem portion (A ₁ ) of the seedling (A) is formed between this concave portion and the upper surface of the seedling extruding portion (18) and the second nail (16). Because it becomes easier for And in such a state, the seedling (A) is easily damaged,
Moreover, the stem portion (A ₁ ) of the seedling (A) is less likely to come off in the field (G).

In the above embodiments, the second pawl (16) is composed of a leaf spring, and the elastic force of the second pawl (16) itself causes the second pawl (16) to come into pressure contact with the upper surface of the seedling extruding part (18). But this second claw (16)
Is composed of a normal flat plate, and the second nail (16) is attached to the seedling extruding part (1
A spring (corresponding to the urging means) that presses against the upper surface of 8) may be separately provided.

In the case of a seedling (A) in which the stem portion (A ₁ ) of the seedling (A) is unlikely to enter between the upper surface of the seedling extruding portion (18) and the second nail (16), the second nail (16) ) May be configured with a round bar.

The present invention can be applied not only to strawberries but also to rice planting nails of rice transplanters for rice.
