Description

[Detailed description of the invention] The present invention has a structure in which a seedling receiving plate member that receives mat seedlings corresponding to a unit planting row is divided into a partition member located between adjacent seedling receiving plate members, By sequentially assembling the seedling receiving plate member and the partition member in such a configuration, it is possible to construct a seedling pedestal with a desired number of planting rows. Compared to configurations with different specifications, by mass-producing seedling receiving plate members and partition members of one specification and selecting the number of them to be used, it is not only possible to easily configure a seedling platform with multiple specifications. Since molding of one specification each for the seedling receiving plate member and the partition member is sufficient, the cost for molding can be kept down;
The present invention relates to a seedling mounting structure for a rice transplanter that has various advantages such as being able to significantly reduce equipment costs.

Conventionally known structures of this type of seedling stand include: Utility Model Publication No. 57-48343 (hereinafter referred to as Conventional Example 1); Utility Model Publication No. 57-2953 (hereinafter referred to as Conventional Example 2); There is one such as that described in Japanese Patent No. 55-29444 (hereinafter referred to as Conventional Example 3), and the configuration of each will be described below.

■ In Conventional Example 1, a side wall is integrally provided on the side surface of the seedling receiving plate member, and a partition member is provided on the opposing side surfaces of the seedling receiving plate members that are close to each other to sandwich the tip edges of the side walls so that they cannot be separated from each other. , ■ In Conventional Example 2, left and right outer frames for guiding the sides of the mat seedlings and partition frames erected at the left and right intermediate portions are formed on the seedling receiving plate member that receives the mat seedlings, and the lateral outer surfaces of the left and right outer frames are formed. The width is approximately 1/2 of the width of the lateral outer surface of the partition frame, and the opposing outer frames are fitted and connected by a partition member that is a mouth-shaped fitting that joins and connects the opposing outer frames, and the partition member and the outer frame are connected to each other. ■ Conventional example 3, which is configured to be fastened with rivets.
In this case, a seedling receiving plate member and a partition member having a cross-sectional opening shape located between adjacent seedling receiving plate members are divided, small protrusions are provided protruding from both long sides of the seedling receiving plate member, and the partition member is A small hole that can fit with the small protrusion is formed on both sides of the member, and the seedling receiving plate member and the partition member are connected by elastic fitting between the two, the small protrusion, and the small hole, and the seedling receiving plate member and the partition member are connected. It has a structure that is attached and fixed to a horizontal stay that is stretched in the width direction of the table.
Such a number of configurations has the following drawbacks.

That is, (a) in Conventional Example 1, the fitting portion between the opposing side wall and the partition member extends over the entire length of the seedling tray in the seedling feeding direction, and the portions over this entire length are inserted and fitted together; There is a drawback that the fitting part between the opposing side wall and the partition member must be machined with high precision, and the assembly work also requires skilled work. Although it is not necessary to carry out precision machining as in Conventional Example 1 to form the joined state, since the connecting force is to be strengthened by riveting, the riveting work requires a great deal of effort. (c) In Conventional Example 3, the connection between the seedling receiving plate member and the partition member is due to the elastic fitting between the small protrusion and the small hole. However, there are disadvantages in that the fitted state tends to become unstable, and when the seedling receiving plate member and the partition member are integrally connected and attached to the horizontal stay, the hand becomes unstable and the attachment work is not easy.

In view of the above circumstances, the present invention has an object to provide a device that can reliably eliminate the conventional drawbacks while taking advantage of the divided structure of the seedling receiving plate member and the partition member.

The characteristic configuration of the seedling mounting table structure in the rice transplanter according to the present invention, which has been made in order to achieve the above object distantly, is that an overhanging side is extended laterally and outwardly from near the lower end of the partition member, and the seedling receiving plate is placed on this overhanging side. While arranging to place the end of the member,
An elastic fitting portion is provided between the overhanging side and the end of the seedling receiving plate member to connect both members in a manner that prevents them from coming out in the lateral and vertical directions;
The point is that there are a plurality of shapes at appropriate intervals along the longitudinal direction of the overhanging side.

The effects of the present invention having such a characteristic configuration are as follows.

In other words, the partition member and the seedling receiving plate member can be connected not only in the lateral direction but also in the vertical direction in a manner that prevents them from coming out by fitting the elastic fitting portions formed on both of them. The work of integrally fitting the receiving plate member and attaching it to the horizontal stay can be easily and easily carried out, and the elastic fitting portion is formed at multiple locations at appropriate intervals along the longitudinal direction of the overhanging side. Therefore, precise machining as shown in Conventional Example 1 is not required, and in addition, it is possible to assemble the corresponding mating parts one after another, and the assembly work itself is very simple. It's easy.

Furthermore, since the overhanging sides are stretched, the section modulus of the partition member increases, and therefore the strength of the partition member and the connecting portion against external forces can be improved.

As described above, it has been possible to provide a structure that is advantageous in terms of accuracy and assembly work without causing a decrease in strength.

Hereinafter, the embodiments of the present invention will be explained based on the drawings.
As shown in the figure, the rice transplanter installed at the rear of the riding machine A is curved in a tilted position to the ground in the rice transplanter B, and is equipped to be able to reciprocate in the lateral direction with respect to the machine's traveling direction. , has a structure of a seedling platform C capable of sending out seedlings in a downwardly sloping manner, and as shown in FIG. The downward opening located between the seedling receiving plate members 1, 1 is a diagonal-shaped partition member 2, and the seedling receiving plate members 1, located on both sides of the seedling receiving plate members 1,
The downward opening located along the outer side of the seedling receiving plate member 1 divides the side frame members 2A, 2A into a diagonal shape.
