Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling stand for a rice transplanter in which seedlings are placed in parallel on each row placement section partitioned by a plurality of intermediate partitions.

[0002]

2. Description of the Related Art In the seedling stand of the above rice transplanter,
Conventionally, for example, as shown in Japanese Utility Model Publication No. 57-48343, side walls are formed on the side surface of the bottom plate on which seedlings are placed,
There has been one in which a connecting tool for sandwiching the leading edge portions of the opposite side walls of the bottom plate so as not to be separated from each other is provided and the bottom plates are connected to form a seedling stand.

[0003]

However, in the above-mentioned conventional structure, when the bottom plates of each strip are connected and assembled,
It is necessary to perform the sandwiching and connecting work by the connecting tool with the side walls of the bottom plates set in the butted state, and there is a drawback that the assembling work or the disassembling work is troublesome, and there is room for improvement. Further, in addition to each bottom plate portion, a connecting tool is required, and the number of parts is increased, resulting in a complicated structure. The present invention aims to eliminate the above-mentioned problems.

[0004]

The characteristic constitution of the present invention is that the seedling stand in the rice transplanter described at the beginning is divided into each row in the middle of the intermediate partition, and the division in the intermediate partition is performed. In the portion, the split seedling stand is configured to be connected and fixed in a positioned state by the fitting engagement of the retaining engagement portions formed on the outer side surface of the vertical wall portion of the intermediate partition. .

[0005]

[Function] When the seedling stand is assembled by connecting the divided seedling stands to each other, it is possible to perform positioning by simply engaging the retaining engagement portions of the adjacent divided seedling stands with each other. It is connected and fixed in the state. Therefore, it is not necessary to perform a troublesome work such as using another connecting member in a state in which each divided seedling stand is aligned along the divided surface, and it is possible to cope with it by an extremely simple operation. Moreover, since the retaining engagement portion is formed so as to project outward, there is little risk that the upper dividing edge of the intermediate partition will come into contact with external objects and be damaged, and the upper dividing edge of the intermediate partition can be aligned in the assembled state. It is less likely that the parts will be displaced.

[0006]

As a result, the rational structure improvement makes it possible to assemble the divided seedling placing table by a very simple operation, thus improving the workability. Further, since the retaining engagement portion is formed on the divided seedling placing table itself, a separate connecting member is not required, the number of parts can be reduced, the structure can be simplified, and the management of parts in manufacturing is easy to perform. It became a thing.

Embodiments will be described below with reference to the drawings. Figure 1
Shows a seedling stand for rice transplanters. This seedling stand is
The seedlings for planting are configured to be placed in parallel on each row placement portion 2 partitioned by the plurality of intermediate partitions 1, and the seedling placement surface 2a of each row placement portion 2 is located on the lower side of the seedling supply direction. Is provided with a vertical feeding device 3 of an endless rotating belt with a projection, and this vertical feeding device 3 transfers a predetermined amount of placed seedlings toward a planting mechanism [not shown] at a lateral movement stroke end of a seedling stand. It is configured to send out. Further, on the seedling placing surface 2a, as shown in FIG. 2, small unevenness 4 is formed alternately in the width direction at the upper side portion to reduce the sliding contact area with the placed seedling. As shown in FIGS. 3 and 4, at the front and rear positions of the vertical feeding device 3, the upper protruding portion 5 is made smaller to further reduce the sliding contact resistance. When mounting the seedling placing base, the divided seedling placing bases 6 divided for each row are connected and assembled. More specifically, as shown in FIG. 5, each divided seedling placing table 6 is configured to be divided substantially in the middle of the upper wall portion 1a of the intermediate partition 1 having a certain predetermined width in the vertical direction. At appropriate points in the direction,
A retaining engagement portion A is formed so as to project from the outer side surface of the vertical wall portion 1b of the intermediate partition 1. That is, an engaging projection 8 having a hook-like elastic engaging piece 7 is formed on the lateral outer side of the vertical wall portion 1b on one side of the split seedling stand 6 and the vertical wall portion 1 on the other side is formed.
On the lateral outer side of b, an engagement recess 10 having a hook-shaped elastic engagement piece 9 with which the engagement projection 8 is fitted and the elastic engagement piece 7 is elastically caught and engaged is formed. There is. The engagement protrusions 8 and the engagement recesses 10 form a retaining engagement portion A. When the retaining engagement portion A is fitted and engaged with each other, the dividing edges of the upper wall portion 1a of the intermediate partition 1, the contact portion 11 integrally extending from the engagement recess 10, and the engagement It is configured such that the contacting portion 12 formed on the vertical wall portion 1b is in contact with and positioned in the lower side of the location where the convex portion 8 is formed. In this way, the divided seedling stand 6 is connected and fixed to each other.

When the strip mounting portions 2 have different widths, as shown in FIG. 6, a spacer member 13 is interposed between the connecting portions of the divided seedling placing bases 6, as shown in FIG. Are engaged and connected. That is, the spacer member 13 has a gate-shaped cross section, a step 14 is formed at the upper end portion into which the dividing edge of the upper wall portion 1a of the intermediate partition 1 is fitted, and the lower end portion is provided with the contact portion. A recess 15 into which 12 is fitted is formed, and an engaging hole 16 into which the elastic engaging pieces 7 and 9 of the engaging projection 8 and the engaging recess 10 are hooked and engaged is formed in the upper and lower portions. In this manner, the intermediate partition 1 can be widened, that is, the width of each strip mounting portion 2 can be narrowed so that the intermediate partition 1 can be connected and fixed by the lateral engagement.

[Other Embodiments] As described above, instead of the intermediate partition 1 having a predetermined width along the vertical direction, as shown in FIGS. It may be formed to have a narrow width and the width may be narrowed. Even in this configuration,
Similar to the above-mentioned embodiment, the retaining engagement portion A is formed so as to project on the outer side of the vertical wall portion 1b of the intermediate partition 1.
Further, when the specifications of the widths of the respective strip mounting portions 2 are changed, as shown in FIG. 9, a spacer member 17 similar to the spacer member 13 is intervened in an engaged and connected state. Even in such a specification that the spacer member 17 is not interposed, the spacer member 17 is connected and attached to the left and right partition parts of the seedling stand.

It should be noted that reference numerals are added to the claims for facilitating the comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
