Description

[Detailed description of the invention] [Technical field of the invention] The invention is such that unit pot seedlings are divided from a group of potted seedlings in which a large number of unit pot seedlings are glued together and formed into a rectangular shape. This relates to a pot seedling dividing device in a rice transplanter.

[Prior art]

This kind of group pot seedling is made of paper tubes of 14 mm square, 20 unit pots in the horizontal direction, and 42 unit pots in the vertical direction connected to each other in a rectangular shape by gluing. The seedlings were placed in a similar seedling-raising box, and the seedlings were sown on the bed filled in the paper tube of each unit pot.

By the way, this potted seedling has the disadvantage that it is more expensive as a whole because it requires seedling raising materials such as paper tubes to separate each unit compared to matted seedlings, but it can be raised in squares. As a result, healthy seedlings can be produced, and since the paper tube protects the roots until planting, rooting and early growth are extremely good without any looseness or damage caused by seedbed collapse, which is the case with mat seedlings. Therefore, it is advantageous for safe rice cultivation in cold regions such as Hokkaido.

Therefore, it is desired to plant these seedlings in cluster pots using a commonly used rice transplanter that divides and plants ordinary mat seedlings.

However, when seedlings in group pots are placed on the seedling stand of a rice transplanter that divides and transplants ordinary mat seedlings and divides them into unit pot seedlings, it is difficult to separate them into unit pot seedlings. If you scrape the seedlings using split claws that match the width of the seedlings, the joint of the paper tube will be cut and the root protection provided by the paper tube will become ineffective, so be careful not to damage the paper tube outside the seedling bed. Therefore, a piercing claw that pierces only the seedbed inside the paper tube is used to stab the seedling from above, with the opposing interval in between, and the descending of the piercing claw separates the paper tubes from each other, dividing the unit pot seedlings and stabbing them. The seedlings must be transported to the seedling planting position in the field in the same condition.

However, since the paper tubes are glued together at the time of planting, they contain moisture and are extremely weak, so when dividing, the paper tubes separate before the piercing nails can penetrate the seedbed sufficiently.
When transporting the seedlings to the planting position, the seedlings may become misaligned or fall off, making it impossible to properly plant them. Since the mounting table has a seedling take-out port facing the planting rod, a piercing claw that plunges from above into the seedbed of the unit pot seedling facing this seedling take-out port separates the glued unit pots. There is a problem in that the seedlings run away to the seedling outlet side and their posture is disturbed, and if the seedlings are planted in the disordered posture immediately before division, good planting cannot be achieved.

[Purpose of the invention] This invention was devised in view of the above-mentioned conventional situation and to eliminate the disadvantages peculiar to potted seedlings. , replace a part of the seedling dividing device.

An object of the present invention is to provide a pot seedling dividing device for a rice transplanter that can orderly divide and plant unit pot seedlings from group pot seedlings.

[Structure of the idea]

The pot seedling dividing device for a rice transplanter according to the present invention which achieves the above object is a rice transplanter equipped with a planting rod having a rod that moves up and down and a claw attachment part at the rear of the rod axis. The mounting part has a pierce that pierces the seedbed of unit pot seedlings from above.

A pair of left and right claws are attached, and a seedbed support bellow is provided at the lower end of the rod to support the front surface of the unit pot seedling. It is characterized in that it is formed into an inclined surface that gradually protrudes backward as it goes upward from the lower end, and the seedlings in group pots are separated into unit potted seedlings by the piercing claws.

〔Example〕

An embodiment of the present invention shown in the drawings will be described below.

1 is pivotally supported so that the middle part A draws a circular locus opening, and the front end pivot part C is provided so as to draw a reciprocating circular locus 2,
This is a normal planting rod for mat seedlings, which is equipped with a rod 3 that moves up and down at the rear end, and a claw attachment part at the rear of the axis of the rod 3.

Behind this planting rod 1, as shown in FIG.
The seedling tray 6 is installed at an angle so that the lower seedling take-out area facing the planting rod 1 is at a lower level and the rear side is at a higher level. ), so there are 204 seedlings in unit pots in the horizontal direction and 4 in the vertical direction.
A group of seedlings grown in a pot is placed in a state in which two seedlings are glued together and combined into a rectangular shape.

A pair of left and right stabbing claws 2 that pierce the seedbed of the unit pot seedling 5 from above are detachably attached to the claw attachment portion of the planting rod 1, and the stabbing claws 2 are attached to the rod 3 side, that is, The front edge 2a is formed into a straight line parallel to the axial direction of the rod 3, and the rear edge 2b is formed into an inclined surface at an angle of θ, which gradually extends toward the rear group pot seedling side as it goes upward from the sharp part at the lower end. It is formed.

At the lower end of the rod 3, a seedbed support bellow 4 is detachably attached via a threaded portion provided on the rod 3 with a nut.

The seedbed support spatula 4 has a linear portion along the front side of the pot seedling 5 so that it can support the front side of the unit pot seedling 5 facing the seedling take-out lower of the seedling mounting table 6 during seedling division. The lower end is slightly inclined toward the front in the moving direction below the lower end of the stabbing claw 2, and extends below the lower end of the potted seedling 5.

This seedbed support spatula 4 has a front edge 2a of a piercing claw 2 so as to come into contact with the top surface 5a of the seedbed of the unit pot seedling 5 when dividing the seedlings.
Left and right support pieces 4a, 4a are provided that protrude toward the seedbed, and the width L1 of this seedbed support spatula 4 is formed to be equal to or slightly narrower than the width of the unit pot seedling. At the same time, the opposing width of the piercing claws 2 is formed to be narrower than the unit pot seedling width.

Although the supporting pieces 4a, 4a are positioned within the opposing width of the piercing claw 2 in FIG. 2C, they may be positioned outside the piercing claw 2.

The claw attachment part of the planting rod 1 is provided with a hole in the upper part and a semicircular locking part in the lower part. Insert a pin that passes between the stabbing claws 2 whose left and right sides are integrally formed, pass a bolt through the hole provided in the stabbing claw 2 and the hole above the claw attachment part, and attach and remove the stabbing claw 2 with a nut. Fix freely.

When dividing unit pot seedlings from the group pot seedlings placed on the seedling placement table 6, insert the sharp lower end of the stabbing claw 2 into the seedbed from above in the paper tube of the unit pot seedling 5 facing the seedling take-out lower. However, the unit pot seedlings 5 facing the seedling extraction lower are pierced gradually deeper into the inclined surface titer bed provided at the rear edge 2b of the stabbing claws 2, with their front side once supported by the seedbed support bellows 4. As a result, the unit pot seedlings 5 are pushed toward the group pot seedlings at the rear, and by the time the piercing claws 2 are pierced to a certain depth,
A disadvantage peculiar to potted seedlings is that the glue that connects unit pot seedlings and collective potted seedlings separates, causing the unit pot seedlings to tilt toward the seedling removal lower side or to be pushed downward, resulting in disordered seedling posture before division. can be prevented.

When the piercing claws 2 have penetrated to a certain depth, the seedbed upper surface 5a of the unit pot seedling 5 is
By contacting the side support pieces 4a, 4a and lowering the planting rod 1, the stabbing claws 2 and the seedbed support bellows 4 are lowered, so that the unit pot seedlings 5 facing the seedling extraction lower are grouped. The unit pot seedling 5 with the glue separated from the pot seedling passes through the seedling take-out lower in a stable state with the stabbing claw 2 sufficiently pierced and the front of the seedbed supported by the seedbed support spatula 4. Since the seedlings 5 in unit pots are transferred at the same planting position, the seedlings 5 in unit pots are kept in the same posture as they were when they were divided, and are transferred in an orderly manner.

As the planting rod 1 continues to descend, the unit pot seedlings 5 pierced and supported by the piercing claws 2 are moved to the seedbed support bellows 1 while being protected by the seedbed support bellows 4 having approximately the same width in front of the movement trajectory B. 4 reaches the end of the circular planting groove C, and at this position, the unit pot seedling 5 is placed by the descending rod 3.
Both shoulders of the upper surface 5a of the seedbed are pushed downward by the support piece 4a4a, and the unit pot seedling 5 is pushed out from the piercing claw 2.
The seeds are planted by pulling out the seedbed.

Therefore, in the present invention, the conventional planting rod 1 for dividing mat seedlings and the seedling mounting table 6 having a seedling take-out lower part are used as they are, and the unit is attached to the claw attachment part of the planting rod 1. The seedling mounting table 6 can be attached to the seedling mounting table 6 by simply replacing the parts by attaching a piercing claw 2 that pierces the seedbed of the potted seedling from above and installing a supporting bellow 4 at the lower end of the rod 3 to support the front surface of the unit potted seedling. Seedlings placed in group pots can be divided into unit potted seedlings.

Then, the unit pot seedling 5 faces the seedling take-out lower part of the seedling placement table 6.
This is because the stabbing claw 2 can begin to penetrate into the seedbed with its front side once supported by the seedbed support spatula 4, and the stabbing claw 2 gradually penetrates deeper into the nursery surrounded by the paper cylinder. The sloping surface provided on the rear edge 2b allows the stabbing claws 2 to penetrate to a predetermined depth while pressing the unit pot seedlings 5 toward the group pot seedlings at the rear. When stabbing the seedlings, it is possible to stab the seedlings without disturbing the seedling posture of the unit pot seedlings 5 facing the seedling extraction lower,
As a result, while the piercing claw 2 pierces to a certain depth, the glue that connects the unit pot seedlings and group pot seedlings separates, and the unit pot seedlings tilt toward the seedling removal lower side or are pushed downward. It is possible to prevent the disadvantages peculiar to potted seedlings, such as the seedlings' posture being disturbed before division.

[Effect of idea]

In short, the pot seedling dividing device for a rice transplanter according to the present invention is suitable for use in a rice transplanter equipped with a planting rod having a rod that moves up and down and a claw attachment portion at the rear of the rod axis. A pair of left and right stabbing claws that pierce the seedbed of the unit pot seedling from above are attached to the claw attachment part of the rod, and a seedbed support bellow that supports the front side of the unit pot seedling is provided at the lower end of the rod, and the front edge of the stabbing claw is attached to the rod. is formed in a straight line parallel to the axial direction of the rear edge, and the rear edge is formed into an inclined surface that gradually extends rearward as it goes upward from the lower end,
Since the piercing claws are used to separate seedlings in group pots into unit pot seedlings, the conventional planting rod for dividing mat seedlings and the seedling mounting table having a seedling take-out port can be used as they are, and the nail attachment part By simply replacing parts, attach a piercing claw that pierces the seedbed of the unit pot seedling from above to the rod, and attach a seedbed supporting bell to the bottom end of the rod to support the front of the unit pot seedling. Potted seedlings can be divided into unit potted seedlings.

Moreover, the seedlings in unit pots facing the seedling take-out port of the seedling table can begin to be pierced into the seedbed with the stabbing claws while the front side of the seedlings is once supported by the seedbed support spatula, and the seedlings are surrounded by paper tubes. As the piercing claw gradually penetrates deeper into the seedbed, the inclined surface provided at the rear edge allows the piercing claw to penetrate to a predetermined depth while pressing the unit pot seedlings toward the group pot seedlings at the rear. In combination, the seedlings can be pierced without disturbing the posture of the seedlings in the unit pots facing the seedling take-out port, so that seedlings in group pots can be divided into unit pot seedlings in an orderly manner without disturbing the posture.

Therefore, potted seedlings can be divided and planted in an orderly manner by simply replacing a part of the seedling dividing device using a conventional rice transplanter that divides pine and tortoise seedlings.
