BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling rest for a rice transplanter having a plurality of seedling receiving portions and a partition for dividing the plurality of seedling receiving portions.

[0002]

2. Description of the Related Art An example of a seedling rest for a rice transplanter as described above is disclosed in Japanese Utility Model Publication No. 4-53214. As shown in FIGS. 2 and 5 of the above-mentioned publication, the lower end of a partition (8 in FIG. 5 of the above-mentioned publication) and a seedling mounting portion (FIG. The end of 7) in the middle is connected to form the entire seedling rest.

[0003]

As described above, when the lower end of the partition and the end of the seedling mounting portion are connected to each other on the seedling rest, the lower end of the partition and the seedling mounting portion are connected to each other. Is located on the upper surface of the seedling placement part.

[0004] When the seedlings placed on the seedling placement part are vertically fed to the seedling takeout side along the seedling placement part, the lower end of the partition part and the end of the seedling placement part are moved. There is a possibility that roots of the seedlings may enter the joints, which may hinder the vertical feeding of the seedlings to the seedling take-out side. An object of the present invention is to provide a seedling rest of a rice transplanter so that seedlings placed on a seedling placement portion are vertically fed to a seedling takeout side without any trouble, and replenishment of seedlings to a seedling rest is provided. It is intended to make it possible to easily perform the operation.

[0005]

A feature of the present invention resides in the following configuration of the seedling rest of a rice transplanter as described above. A seedling holder is provided with a plurality of seedling placement parts and a partition part for partitioning the plurality of seedling placement parts, and the width of the upper part in the vertical feeding direction of the seedlings in the partition part is set to the width of the partition part other than the upper part. By setting it to be narrower than the width, the upper part in the vertical feeding direction of the seedling in the partition part is divided into one vertical wall part and the other vertical wall part along the vertical feeding direction of the seedling. Then, the divided walls are configured so that the inner surfaces of one and the other vertical wall portions of the divided wall portions are abutted at a predetermined vertical width, and the partition walls other than the upper wall are arranged along one of the upper walls along the vertical feeding direction of the seedling. Part and the vertical wall part, and the other upper wall part and the vertical wall part, so that one of the divided partition parts and the other upper wall part are abutted and divided. A state in which the inner surfaces of one and the other vertical wall portions of the partition portion are abutted at a predetermined vertical width, and divided.

[Action]

[I] According to the features of claim 1, since the seedling rest provided with the plurality of seedling placing portions and the partition portions is divided at the upper wall portion and the vertical wall portion of the partition portion, the divided seedling rests are placed. In the connected state of the stands (partitions), the divided part of the seedling rest is not located on the upper surface of the seedling placing part. As a result, when the seedlings placed on the seedling placement part are fed vertically to the seedling takeout side along the seedling placement part, the roots of the seedlings do not enter the divided part of the seedling rest, Is smoothly fed vertically along the seedling mounting portion toward the seedling takeout opening side.

[II] According to the feature of the first aspect, the divided seedling rest (partition part) is connected by the connecting part in a state where the upper wall part and the vertical wall part of the divided part are abutted. Is configured. In this case, when the upper wall portion and the vertical wall portion of the divided partition portion are abutted, the width of the partition portion is determined by the abutting portion. There is no need to prepare.

Thus, the function of determining the width of the partition,
And the function to prevent the separated seedling rest from coming off
If one function is provided in the connecting part, a relatively complicated connecting part having these two functions is required.
According to the feature of (1), since it is not necessary to provide a function for determining the width of the partition portion in the connecting portion, it is possible to simply configure the connecting portion by not providing this function.

[III] In general, rice transplanters often replenish the seedlings so as to slide them into the seedling mounting portion from the top in the longitudinal feed direction of the seedling nest. According to the feature of claim 1, since the width of the upper part in the vertical feeding direction of the seedlings in the partition part is set to be smaller than the width of the partition parts other than the upper part, in the upper part in the vertical feeding direction of the seedlings. The width of the seedling placing portion (the distance between the vertical wall portion of the partition portion and the vertical wall portion of the adjacent partition portion) is slightly wider. Therefore, according to the first aspect of the present invention, when replenishing seedlings from the top in the vertical feeding direction of the seedlings in the seedling placing stand, the width of the seedling mounting portion (the vertical wall portion of the partitioning portion and the adjacent partitioning portion) as described above. (A distance from the vertical wall of the section) is slightly wider, so that the seedlings can be replenished so as to be easily slid into the placement section.

[IV] According to the feature of the first aspect, as described in the above item [III], the width of the seedling placing portion (the interval between the vertical wall portion of the partition portion and the vertical wall portion of the adjacent partition portion) is set. When it is assumed that the width is a little wider, at the upper part in the vertical feeding direction of the seedling in the partition part, the inner surfaces of one and the other vertical wall parts of the divided partition part are connected so as to abut with a predetermined vertical width. I have. As a result, the vertical wall portions of the divided partition portions are superimposed on the upper portion of the seedlings in the vertical feeding direction in the partition portion, so that the vertical wall portion has an apparently twice as thick thickness. Has sufficient strength. Therefore, [II
As described in I), when replenishing the seedlings by sliding them into the seedling mounting portion from the top in the vertical feeding direction of the seedlings on the seedling mounting table, the seedlings are placed on the vertical wall of the divided partition. Even if it hits, the situation where the vertical wall part of the divided partition part is deformed does not occur.

[V] Further, according to the feature of claim 1, in the vicinity of the upper part in the vertical feeding direction of the seedlings in the partition portion, the rear surface of the plurality of seedling placing portions is arranged along the direction orthogonal to the vertical feeding direction of the seedlings. In the vicinity of the upper part in the vertical feeding direction of the seedlings in the partition portion, the reinforcing member is attached so that the vertical wall portion having sufficient strength and the reinforcing member intersect in a cross shape. And the seedling placement part in the vicinity has sufficient strength.

[0012]

According to the first aspect of the present invention, in a seedling rest of a rice transplanter composed of a plurality of seedling placing portions and partition portions, the seedling rest is divided into an upper wall portion and a vertical wall portion of the partition portion. By doing so, the seedlings can be smoothly fed vertically to the seedling takeout side along the seedling mounting part without the roots of the seedlings getting into the divided part of the seedling rest, and planting of the rice transplanter The attachment performance was improved. A portion which may be called an existing portion, which is a butt portion of the upper wall portion and the vertical wall portion of the divided partition portion, without providing the function of determining the width of the partition portion to the connecting portion as in the feature of claim 1. In this case, the connection portion can be simplified.

According to the first aspect of the present invention, the width of the seedling placing portion (the distance between the vertical wall portion of the partition portion and the vertical wall portion of the adjacent partition portion).
However, by configuring the seedlings to be slightly wider, the seedlings can be easily replenished by sliding the seedlings into the seedling mounting portion from the upper part in the longitudinal feed direction of the seedling mounting table. Thus, the workability of the rice transplanter could be improved. In this case, by arranging the vertical wall portion having sufficient strength and the reinforcing member, which are overlapped with each other in the partition portion, so as to intersect in a cross shape, the seedlings near the upper portion in the vertical feeding direction of the seedlings in the seedling mounting table. Since the mounting portion had sufficient strength, the durability of the seedling rest could be improved.
