Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transplanting machine for transplanting, for example, vegetable seedlings onto a ridge, and more specifically, it has a running part and a transplanting part, and moves to the transplanting part along the side of the ridge. The present invention relates to a transplanter equipped with a pair of culture wheels.

[0002]

2. Description of the Related Art Conventionally, this type of transplanter is disclosed in, for example, Japanese Patent Laid-Open No.
As disclosed in Japanese Patent No. 173005, front wheels and drive wheels that are rotationally driven by the engine are supported on both sides in the front-rear direction of a machine equipped with an engine and the like and transplanted on the rear side of the machine. Parts are provided.

The transplanting section transports a seedling tray having a plurality of seedling accommodating sections, and a seedling take-out claw for extracting pot seedlings from the seedling accommodating section of the seedling tray conveyed by the seedling conveying section.
The potted seedlings taken out by the seedling attachment claws are provided, and an openable / closable transplanting nail is planted on the ridges, and a pair of left and right cultivation wheels for cultivating soil in the potted seedlings planted by the transplanting nails is provided.

Further, each of the soil rings is rotatably supported on the rear side of the transplanted nail at both left and right positions of the planted seedling by the transplanted nail, and the pot seedlings are planted in the ridges. At the time of attaching work, each of the cultivation wheels is rolled while following the machine on a predetermined movement locus at both left and right positions of the planting seedlings by the transplanting nails, and the soil on the ridge upper surface is rolled by the rolling of each cultivation wheel. The soil is sown while being brought closer to the planting side with the transplanted nails.

However, when the pot seedlings are planted on the ridges, while the machine body is being driven by the rotation drive of the drive wheels, the transplanting pawls are closed and the stand-up position for raising seedlings is waited. When the seedlings are taken out, the pot seedlings are taken out from the seedling storage portion of the seedling tray conveyed by the conveying portion by the seedling taking nails and discharged into the transplanting nails, and then the transplanting nails are moved to the seedling planting position on the lower side. And then plunge into the ridge, and at this time, the transplanted nail is opened to plant the pot seedling inside the ridge, and after planting the pot seedling with the transplanted nail, the planting with the transplanted nail is performed. By each cultivation soil ring that is moved following the machine on a predetermined movement locus on both left and right sides of the seedlings, the soil on the ridges is cultivated in the planted pot seedlings while being moved from the left and right sides to the planting seedling side. It is.

[0006]

However, in the above transplanting machine, each culture soil ring is rotatably supported on the left and right sides of the planted seedling on the rear side of the transplanted nail, and the pot seedling is formed by the transplanted nail. During the work of planting on the ridges, each of the cultivation wheels rolls following the running of the machine body, and each of the cultivation wheels always rolls along the predetermined movement locus at both left and right positions of the planted seedlings. Therefore, depending on the soil quality of the ridges, it may not be possible to surely cultivate soil for the planted seedlings, for example, when the soil quality of the ridges is too hard or too soft, the seedlings planted by each soil ring. The soil cannot be smoothly collected to the side, and as a result, the amount of cultivated soil for the planted seedlings is insufficient,
There was a risk that the growth of the planted seedlings would be adversely affected.

An object of the present invention is to ensure that a sufficient amount of soil can always be cultivated for seedlings to be transplanted at the transplanting part without being affected by the soil quality of the ridges.

[0008]

In order to achieve the above object, the present invention has a pair of paddle wheels 6 having a running portion 3 and a transplant portion 4 and moving along the side of the ridge in the transplant portion 4. In the transplanting machine having attached thereto, each of the soil wheels 6 can be opened and closed in a direction in which they approach or separate from each other in the width direction of the ridge via a pair of rocking arms 7 pivotally attached to the transplanting section 4. In addition to supporting, the swinging arms 7 are opened and closed in conjunction with the transplanting operation of the transplanting part 4.

[0009]

According to the transplanting machine described above, when the seedlings are planted by the transplanting section 4, the rocking arms 7 are opened and closed in association with the transplanting operation of the transplanting section 4, and each of the swinging arms is opened and closed. Each of the soil wheels 6 supported by the arm 7 is moved toward and away from the ridge width direction.

That is, until the transplanting portion 4 performs the transplanting operation, the padding wheels 6 are located on the outer side in the ridge direction apart from each other via the swinging arms 7, and the transplanting portion 4 is also located. When the seedlings are transplanted by performing the transplanting operation, the cultivating rings 6 move via the swinging arms 7 toward the inner side in the ridge width direction which is close to each other. When moving from the outer side to the inner side in the direction, the soil of the ridge is forcibly scraped to the seedling side transplanted in the transplanting section 4.

Therefore, regardless of the soil condition of the ridges, a sufficient amount of soil can be cultivated for the seedlings, and at the time of transplanting work by the transplanting section 4, seedling transplantation by the transplanting section 4 is carried out. It is possible to surely cultivate sufficient soil for all the seedlings transplanted on the ridges by repeatedly moving the cultivating rings 6 to the outer side and the inner side in the ridge width direction in conjunction with the operation. Therefore, each of these seedlings can be grown well.
