Description

[Detailed Description of the Invention] 1 vJ of tree seedlings is obtained by seedling ±(q) seedlings on a seedling stand.
Q□+ It relates to a method for taking out seedlings for a rice transplanter, in which block-shaped seedlings are removed from the seedlings with soil using a planting claw.

Conventionally, when taking out seedlings by the above-mentioned seedling taking method, as shown in FIG. Removal width (
The seedling is located approximately in the middle of the (It), and the planting nail (
The seedlings were taken out one after another so that no bed soil remained between the block-shaped seedling removal marks in step 6), but the shaking condition of the seedlings on the center side between each shoot was sparse, so the planting nails ( 6) The bed soil in the area holding the block-shaped seedlings easily collapses, making it impossible to reliably hold the block-shaped seedlings in the proper posture.
6) There are problems such as the plant falling off and becoming a large plant, or the bacteria falling over when planting on a mud surface, which is especially noticeable when planting adult seedlings where the bed soil of block-shaped seedlings is large. That was a problem.

In view of the above-mentioned conventional circumstances, an object of the present invention is to provide a simple and rational improvement method that enables block-shaped seedlings to be securely held in the planting nails, thereby enabling good seedling planting fJ. It is in the point of doing.

In the method of the present invention for taking out seedlings for a rice transplanter, the distance between the seedlings being taken out by the planting claws is made smaller than the row-seeding gap of the seedlings in the soil, and the gap between the block-shaped seedlings taking out by the planting claws is So that the floor remains on the! iQ seedling mounting table and seedling planting (=
It is characterized by providing a correlation to the relative movement of the J claws.

To do this, leave the center part between each shoot where the seedlings are sparsely rooted, and use the planting nails to hold the upper part of the bed near the seedlings where the roots are dense and are less likely to cause landslides, and plant block-shaped seedlings one after another. Since the seedlings are taken out, it is possible to further prevent the block-shaped seedlings from falling off the planting claws due to collapse on the floor, and from falling over when planting on muddy surfaces, resulting in extremely good seedling planting. , since it is a simple improvement to the conventional I'll transplanter by simply setting the time during which seedlings are taken out by the planting claw to be smaller, [1-1 Production and economic aspects of the transplanter] It has also come to be advantageous.

Next, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in Figs. 1 and 2, power is transmitted from the passenger vehicle body via a telescopic and bendable transmission shaft + Received planting mission case (21fj, + mat-like moe (
The inclined box mounting table (3) on which the W) are placed side by side,
The seedling tray (W) is connected to the seedling tray (3) through a notch (5) formed in the sliding piece (4) that is arranged so as to be movable horizontally and reciprocally at a constant stroke, and which receives the lower end of the seedling tray (W). The planting claws (6
) are installed in parallel between the lateral forces of the aircraft, and a seedling stand (3) is installed.
Each time the rice reaches the stroke end, a rotary locking feeder (7) is provided to send the seedlings downward, which is also equipped on a riding rice transplanter. It is.

The mat-like bacteria (W) are placed on a bed of a vertically long rectangular shape in plan view (with a pattern pattern with respect to Al at equal pitches in the disease direction).
P=, 2a%) is sown in vertical rows, and the seedlings are germinated, rooted, and grown.
To take out block-shaped seedlings one by one, as shown in Figure 8, a notch for removing block-shaped seedlings (
The opening ij (/1) of 5) is set to 20%, which is equal to the row pitch (P) of the cloak Buddhist painting (W), and the notch (
A pair of bent plate-shaped claw members (6a) arranged so as to be symmetrical in cross-sectional view with respect to the center line of the opening width of 6).
The width (13) of the block Buddhist painting stem/leaf part penetrating part (6b) formed between the upper s-planes of the nail members (6a) and the outer middle (12) of the planted nails (6) is 75%. )of! %〜

During the opening of the horn notch fi+ (4i), that is, the row sowing pitch (P) K is equal to 2 (7%), and when the bacteria are harvested by the planting claws (6), the row sowing center of the mat-like uj (W) is The relative movement of the seedling stand (3) and the planting claw (6) is correlated so that the line approximately coincides with the center line of the opening rlJ of the notch (5), and thereby the mat-like seedling (W) is Plant the bed soil (N) in the center between the vertical stripes with the soil (N) left behind (K F
There is no N.

In other words, in the cloaked Buddha painting (W), the central part of each city where the rooting condition of the surface is sparse is collected, and the area above the floor near the box where the rooting is dense and less likely to cause landslides is planted with planting nails ( 6)
By holding the block-shaped seedlings out, the planting nails of the block-shaped seedlings (6

By forming the size larger than 5%, which is the third dimension (14), it is possible to prevent the HT valve from shifting by one angle in the direction of disease in the pattern when seeding rice rows on the bed soil (A), and to make it easier for planting. The structure is such that the collection of block-shaped seedlings by the claws (6) is made even smoother.

To explain the seedling planting iq claws (6) in more detail, as shown in FIGS. 2, 3, and 4, the height dimension (H) of one portion of the outer surface of each claw member (6a) is Form it to a size that is larger than the outer middle (j2) dimension of the planting claw (6), and the width (l, ) of the block-shaped seedling bed to be taken out is also sufficiently large. , is configured to more reliably prevent the collapse of the block-shaped seedlings held on the bed (A) inside the claw members (6@) ii + the same, and to further ensure the retention of the block-shaped seedlings. , both claw members (on the upper surface of the sixth
A plate-shaped residual floor scraping device (8) whose overall outer diameter is slightly smaller than the 'l' (/+) of the notch (6) of No. 1 is integrally attached, and the planting nail (6) is installed. Immediately after taking out the block-shaped seedlings, pass the scraping tool (8) into the notch (5) to scrape off the floor (A) left behind by the planting claws (6), and then place the seedlings on the seedling stand (3). The structure is such that the downward feeding of the mantle soft bacteria (Wl) when it reaches the stroke end is not inhibited by the residual bed soil.

In addition, the row sowing pitch (P) of Mantle soft bacterium (W), the seedling removal width (/2) of the planting claw (6) which is set smaller than that, and the seedling removal width (/2) of the planting claw (6). Width (13) of the stem leaf part penetration part (6b) and height H of the planting nail (6)
Specific dimensions such as dimensions can be changed as appropriate.

In order to remove the floor ± (A) left behind by the planting claw (6), it is necessary to attach several types of scraping tools (8) of various shapes to the planting claw (6). Alternatively, various pear-type residual bed soil removal devices may be provided in the notch (5) of the sliding frame (4).
