Description

[Detailed description of the invention] The present invention includes, for example, horizontally installing a seedling stand guide rail shorter than this distance between a pair of left and right wheels, and a pair of left and right seedling stands being placed between the left and right pair of wheels. The present invention relates to a walking rice transplanter installed via the guide rail so as to be reciprocally movable. Conventionally, as shown in Japanese Utility Model Application Publication No. 47-32812, there has been a technique in which a pine seedling cutting blade is attached to a seedling stand and the pine seedlings are cut row by row by the planting claws.

However, when a spare seedling carrier is provided with a short side width that is about twice that of the seedling carrier, and a mat seedling is cut in half lengthwise and half of that mat seedling is supplied to the seedling carrier, that is, when a seedling carrier having a width about half that of the conventional carrier is attached and mass-produced mat seedlings of conventional sizes are used for rice planting, the above-mentioned conventional technology does not cut the mat seedlings to fit the size of the seedling carrier, so it is necessary to load mass-produced mat seedlings that have been cut in half lengthwise in advance onto the spare seedling carrier and perform rice planting work, which poses problems such as the mat seedlings being prone to deformation and damage, and also poses problems such as the difficulty of reducing the labor required for seedling raising and transporting the mat seedlings by forming special mat seedlings with a width about half that of the conventional ones to fit the size of the seedling carrier when raising the seedlings.

However, in the present invention, a pine seedling cutting blade is provided on a preliminary seedling platform having a short side width approximately twice that of the seedling platform, and the pine seedling cutting blade is installed in the center of the short side width of the preliminary seedling platform. Attaches freely in the long direction,
The pine seedlings on the preliminary seedling platform can be cut into approximately half in the longitudinal direction using a pine seedling cutting blade.

Therefore, by dividing the pine seedlings on the preliminary seedling platform into two in the longitudinal direction, it is possible to easily obtain pine seedlings of a size suitable for the seedling platform by preventing the pine seedlings from deforming and damaging the seedlings. Using conventional mass-produced pine seedlings, it is possible to easily form pine seedlings for special seedling stands that are smaller than conventional ones, and the pine seedlings held on the preliminary seedling stand can be cut with a pine seedling cutting blade. Therefore, by being able to cut the pine seedlings each time when replenishing the seedling stand, it is possible to easily transport the pine seedlings to the field, etc., and it is also possible to cut the pine seedlings each time when replenishing the seedling stand. Compared to special formation, the labor for raising seedlings and the handling of pine seedlings can be simplified and costs can be reduced easily.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.
