[0001]

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 partitioning 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. As a result, when the seedlings placed on the seedling placement section are fed vertically to the seedling removal port side, the roots of the seedlings may enter the junction between the lower end of the partition section and the end of the seedling placement section. Therefore, there is a risk that the vertical feeding of the seedlings to the seedling takeout side may be hindered. SUMMARY OF THE INVENTION It is an object of the present invention to provide a rice seedling placement stand in a rice transplanter, in which a seedling placed on a seedling placement portion is vertically fed to a seedling removal opening side without any trouble.

[0004]

A feature of the present invention resides in that the seedling rest of the rice transplanter as described above is configured as follows. A seedling rest is provided with a plurality of seedling placement parts and a partition part for partitioning the plurality of seedling placement parts.In the upper wall part of the partition part, one of the partition parts is arranged along the longitudinal feeding direction of the seedling. It was divided into the upper wall portion and the vertical wall portion and the other upper wall portion and the vertical wall portion, and the one of the divided partition portions was abutted with the other upper wall portion in a state where they were abutted. A connecting portion for connecting the partition portion is provided inside the partition portion, and a covering portion for covering the butting portion of the upper wall portion of the partition portion from above is formed integrally with the upper wall portion of the partition portion.

[0005]

According to a first aspect of the present invention, a seedling nest having a plurality of seedling placing portions and a partition portion is divided at an upper wall portion of the partition portion and is disposed inside the partition portion. Since the divided seedling rests (partitions) are connected by the connected part, the divided part (separation part) of the seedling rest (upper part) is placed on the upper surface of the seedling placement part in the connected state of the divided seedling rests (partitions). (Abutting part) is not positioned. This allows
When the seedlings placed on the seedling placement part are fed vertically to the seedling take-out side, the seedlings do not enter into the divided part (butting part) of the seedling rest, and the seedlings move to the seedling take-out side. It is fed vertically smoothly.

[II] For example, it is conceivable to provide a divided portion of a seedling rest on the vertical wall portion of the partition portion, but with such a configuration, the seedlings placed on the seedling placing portion are fed vertically to the seedling removal opening side. At this time, the stems of the seedlings may enter the divided portions of the seedling rest. On the other hand, according to the feature of the first aspect, since the divided portion (butting portion) of the seedling rest is provided on the upper wall portion of the partition portion, the seedling near the vertical wall portion of the partition portion is located on the vertical wall side. Even if the seedlings fall, the fallen seedlings rarely touch the divided portion (butting portion) provided on the upper wall portion of the partition portion. Abutting part).

[III] According to the first aspect of the present invention, the divided seedling rests (partitions) are connected to each other by the connecting parts in a state where the upper walls of the divided partitions are abutted against each other. I have. In this case, when the upper walls of the divided partitions are abutted against each other, the abutted portions can prevent the divided partitions from approaching a predetermined amount or more. Thus, according to the first aspect of the present invention, it is not necessary to provide the connecting portion with a function of stopping the divided partitions from approaching the predetermined portion or more, so that the connecting portion can be simply configured.

[IV] When the divided seedling rests (partitions) are connected by connecting parts with the upper walls of the divided parts facing each other, the divided parts are divided due to slight deformation or the like. There may be a gap at the butted portion of the upper wall of the partition. When such a gap occurs, it develops into deformation of the partition,
There is a risk that the vertical feeding of the seedlings at the seedling mounting part will be hindered. According to the first aspect of the present invention, the cover portion is integrally formed on the upper wall portion of the partition portion, and the butted portion of the upper wall portion of the divided partition portion is covered from above by the cover portion. In the upper wall part, the portion of the cover part becomes thick and reinforced, and the generation of a gap at the abutting part of the upper wall part of the divided partition part and the development of the deformation of the partition part Can be suppressed.

[V] In the case where a covering portion for covering the butted portion is provided as described above,
It is also conceivable to provide a cover part of a separate member from the partition part, so that the cover part is attached to the partition part later.However, with such a configuration, it is possible to cover the butted part with the cover part. Since a gap may be formed in a portion where the cover portion is attached to the partition portion, seedlings placed on the seedling placement portion may enter the portion where the cover portion is attached to the partition portion.

According to the first aspect of the present invention, the cover is formed integrally with the upper wall of the partition.
No gap is formed in the portion where the cover portion is formed in the partition portion, and the seedlings placed on the seedling placement portion do not enter the portion where the cover portion is formed in the partition portion. Further, according to the first aspect of the present invention, since the covering portion is located on the upper wall portion of the partition portion and is not located on the horizontal wall portion of the partition portion, as described in the above item [II], the vertical portion of the partition portion is provided. Even if the seedlings near the wall part fall down to the vertical wall side, the falling seedlings rarely touch the covering part in the partition part. By forming the cover part integrally with the upper wall part of the partition part as in the feature of claim 1, it is possible to form the cover part of stable quality without strong variation.

[0011]

According to the first aspect of the present invention, in a seedling rest for a rice transplanter constituted by a plurality of seedling placing portions and partition portions, the seedling rest is divided by an upper wall portion of the partition portion,
By constructing so as to connect the divided seedling rests by the connecting part arranged inside the partition part, the roots and stems of the seedlings placed on the seedling placing part are divided into the seedling rest parts (butting). Part), the seedlings can be smoothly fed vertically to the seedling take-out side without being penetrated, and the planting performance of the rice transplanter could be improved.

As described in the first aspect of the present invention, the connecting portion does not have a function of stopping the divided partition from approaching the predetermined portion or more, and the butted portion of the upper wall portion of the divided partition is effectively used. Then, by providing the above-described function to the butting portion, the connecting portion could be simplified.
Further, by arranging the connecting portions by effectively utilizing the space called the inside of the partition portion, it is advantageous in terms of making the entire seedling rest compact.

[0013] According to the first aspect of the present invention, by providing a cover for covering the butted portion of the upper wall of the divided partition from above, the gap at the butted portion of the upper wall of the divided partition is provided. Occurrence and deformation of the partitioning portion could be prevented beforehand, and the seedlings could be smoothly fed vertically to the seedling takeout side, so that the planting performance of the rice transplanter could be further improved.

According to the first aspect of the present invention, since the cover is formed integrally with the upper wall of the partition, no gap is formed in the formation of the cover in the partition. The seedlings placed on the seedling placement part are less likely to touch the cover part of the partition part, and the seedlings placed on the seedling placement part do not enter the formation part of the cover part in the partition part. This is advantageous in that it is smoothly fed vertically to the outlet.

According to the first aspect of the present invention, by forming the cover part integrally with the upper wall part of the partition part, it is possible to form the cover part of a stable quality without strong variation. Since the reinforcement of the upper wall portion of the partition portion by the covering portion becomes stable in strength, the generation of a gap at the butting portion of the upper wall portion of the divided partition portion and the deformation of the partition portion are further improved. Can be prevented.
