[1]

A seedling mounting table is provided with a plurality of seedling mounting portions and a partition portion for partitioning the plurality of seedling mounting portions.In the upper wall portion of the partition portion, one of the partitioning portions extends along the longitudinal feeding direction of the seedling. A connecting portion that divides the upper wall portion and the vertical wall portion and the other upper wall portion and the vertical wall portion, and connects the one and the other upper wall portions of the divided partition portions in abutted state. Is provided on the back surface of the upper wall portion of the partition portion.

[2] A seedling mounting table is constituted by including a plurality of seedling placement portions and a partition portion for partitioning the plurality of seedling placement portions, and the partition portion is vertically fed at the upper wall portion of the partition portion. By dividing the upper wall portion and the vertical wall portion along the direction into the upper wall portion and the vertical wall portion, and engaging from the direction orthogonal to the vertical feeding direction of the seedlings, An engaging connecting portion that connects the divided wall portions in a state where one and the other upper wall portions of the divided wall portions are abutted with each other,
It is provided on the back of the upper wall of the partition.

[0007]

[I] According to the features of claims 1 and 2, the seedling mounting table having a plurality of seedling placing portions and partition portions is divided at the upper wall portion of the partition portion, and the upper wall of the partition portion is provided. The divided seedling rest (upper wall part of the partition) is connected by the coupling part (engagement coupling part) provided on the back surface of the part, so that the divided seedling rest (upper wall of the partition part) is connected. In the connection state of (1), a state in which the divided portion of the seedling mounting table is located on the upper surface of the seedling mounting portion does not occur. Thereby, when the seedlings placed on the seedling placement part are vertically fed to the seedling takeout side along the seedling placement part,
The seedlings are smoothly fed vertically to the seedling take-out side along the seedling mounting portion without the roots of the seedlings entering the divided portions of the seedling mounting table.

[II] If the connecting portion (engaging connecting portion) is separated from the butted portion of the upper wall portion of the divided partition portion, the upper wall portion of the divided partition portion and the connecting portion (engaging connecting portion) are separated from each other. ) Is bent, and even in the connection state by the connection portion (engagement connection portion),
There may be a gap at the abutting portion of the upper wall portion of the divided partition portion. When such a gap is generated, the partition portion may be deformed, which may hinder the vertical feeding of the seedlings in the seedling placing portion.

According to the features of the first and second aspects, the connecting portion (engaging connecting portion) is provided on the back surface of the upper wall portion of the partition portion, and the connecting portion is provided at the abutting portion of the upper wall portion of the divided partition portion. Since the (engagement connection portion) is close to the above, a state in which deflection occurs at a portion between the upper wall portion of the divided partition portion and the connection portion (engagement connection portion) as described above. And the occurrence of a gap in the abutting portion of the upper wall portion of the divided partition portion can be suppressed. Accordingly, it is possible to suppress a state in which the partitioning portion is deformed and hinders the vertical feeding of the seedlings in the seedling placing portion.

[III] According to the features of claims 1 and 2, since the connecting portion (engaging connecting portion) according to the above item [I] is provided on the back surface of the upper wall portion of the partition portion, it is divided. In the connection state of the seedling mounting table (upper wall portion of the partitioning portion), this connecting portion (engaging connection portion) does not protrude from the partitioning portion to the back side of the seedling mounting table. Thus, when the seedling mounting table is supported on the seedling placement device so as to be able to move laterally, the connecting portion (engagement connecting portion) described in the above [I] does not hinder the support.

[IV] For example, as shown in FIG. 1, when assembling by connecting the divided seedling mounting bases (upper wall portion of the partitioning portion), a direction perpendicular to the longitudinal feeding direction of the seedlings (for example, a paper surface of FIG. 1) By moving the divided seedling rests (upper wall part of the partition) close to each other along the left and right direction), the divided seedling rests (upper wall part of the partition part) are connected and assembled. However, it is considered a common sense assembly form.

According to the second aspect of the present invention, since the engagement connecting portion engages from a direction perpendicular to the longitudinal feeding direction of the seedlings, the divided seedling mounting base (the upper wall portion of the partition portion) is connected as described above. In the assembling process, the moving direction of the divided seedling mounting table (upper wall portion of the partition portion) is substantially the same as the direction of engagement of the engagement connecting portion. Thereby, when connecting the divided seedling mounting bases (upper wall portions of the partitioning parts) and assembling them, the divided seedling mountings are placed in a direction orthogonal to the vertical feeding direction of the seedlings, which can be said to be a common-sense assembly form. If the platform (upper wall portion of the partition portion) is moved, the engaging connection portion is engaged as it is, and the divided seedling mounting platform (upper wall portion of the partition portion) is connected.

[0013]

According to the first and second aspects of the present invention, in a seedling mounting table of a rice transplanter constituted by a plurality of seedling mounting sections and partition sections, the seedling mounting section is divided at an upper wall portion of the partition section, The seedling rest (upper wall part of the partition) divided by the connecting part (engagement connecting part) arranged inside the partition part
Are connected so that the roots of the seedlings do not enter the divided portion of the seedling mounting table, and the seedlings can be smoothly fed vertically to the seedling takeout side along the seedling mounting portion. Thus, the planting performance of the rice transplanter could be improved.

According to the first and second aspects of the present invention, the connecting portion (engaging connecting portion) is provided on the back surface of the upper wall portion of the partition portion, so that a gap is formed in the butted portion of the upper wall portion of the divided partition portion. Can be prevented from occurring, so that it is possible to prevent the deformation of the partition portion from hindering the vertical feeding of the seedlings in the seedling placing portion, and the seedlings can be moved along the seedling placing portion. The seedlings were smoothly fed vertically to the seedling outlet side, and the planting performance of the rice transplanter could be further improved.

According to the first and second aspects of the present invention, the connecting portion (engaging connecting portion) provided on the back surface of the upper wall of the partition does not project from the partition to the back side of the seedling mounting table. When supporting the seedlings in the seedling mounting apparatus so as to be able to move laterally, the connecting portion (engaging connecting portion) does not hinder the support, and the structure for suppressing the support structure of the seedling mounting table is suppressed. It became advantageous. Furthermore, by arranging the connection portions (engagement connection portions) by effectively utilizing the space inside the partition portion, it is advantageous in terms of making the entire seedling mounting table compact.

According to a second aspect of the present invention, the engaging connection is performed in a direction perpendicular to the longitudinal feeding direction of the seedlings, which may be a common sense of assembling the divided seedling mounting bases (upper wall portions of the partitioning portions). By configuring so that the parts are engaged, if the divided seedling mounting base (upper wall part of the partition part) is moved in the direction orthogonal to the longitudinal feeding direction of the seedlings, the engagement connection part can be easily made as it is. , So that it has good assemblability.
