Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transplanter.

[0002]

2. Description of the Related Art Conventionally, as one form of transplanter, a self-propelled traveling device is provided with a seedling feeding device and a seedling planting device, and a pot for one stock in a seedling tray supplied by the seedling feeding device. In some cases, the seedlings are taken out by the seedling take-out nails of the seedling planting device, and are transferred to the seedling-planting nails so that the pots can be moved to the field by the same seedling-planting nails.

In the above-mentioned transplanting machine, the plant interval of seedlings can be adjusted according to the type of seedlings to be transplanted.

For example, the operation locus of the seedling take-out nail can be adjusted by adapting it to the desired seedling spacing, and the operation locus of the seedling take-out nail can be set to the minimum seedling spacing of seedlings. The operating speed of is adapted to the desired seedling interval and can be adjusted.

[0005]

However, the following problems have arisen in the above-mentioned inter-plant regulation of seedlings.

That is, the operation locus of the former seedling take-out nail is
When it is possible to adjust it according to a desired plant interval, the work of adjusting the operation locus of the seedling take-out nail becomes complicated.

In the latter case, when the operating speed of the seedling take-out nails can be adjusted by adapting to the desired seedling interval, the running speed of the traveling device is set at the minimum seedling interval setting (maximum setting of the number of seedlings taken out). Therefore, when the maximum seedling interval was set, the operation of the seedling ejection claw was significantly slower than when the minimum seedling interval was set, and the transplantation work efficiency was significantly reduced.

[0008]

Therefore, in the present invention, a self-propelled traveling device is provided with a seedling supply device and a seedling planting device, and seedlings supplied from the seedling feeding device by the seedling planting device are used in the field. In the transplanter that can be transplanted to, while the seedling planting device sets the transplanting operation speed of transplanting the seedlings to the field from the seedling supplying device to a constant high speed, and an inter-plant adjusting means for adjusting the plant interval of the transplanted seedlings. A transplanter characterized by comprising a traveling speed adjusting means for adjusting the traveling speed of the traveling device, and an interlocking means for interlocking the inter-stock increase / decrease adjustment by the inter-stock adjusting means and the traveling speed increase / decrease adjustment by the traveling speed adjusting means It is intended to be provided.
