Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spare seedling mounting for a rice transplanter which is mounted on a support standing on a traveling machine body in a cantilever shape extending laterally outward from the support.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 10, a spare seedling mounting table 20 of a rice transplanter as described above has a plurality of front-back ribs 2 at a predetermined distance in the left-right direction on a bottom surface 20A.
0a, a plurality of right-and-left ribs 20b that are spaced apart from each other by a predetermined distance in the front-rear direction, and peripheral ribs 20c that are along the outer periphery. It was composed of a resin molded product reinforced by embedding it in a state of extending laterally outward from 23. As a result, the spare seedling mounting table 20 is mounted in a cantilever manner, and thus may be generated when the spare seedling is placed. It has a rigidity enough to prevent the occurrence of the seedling, so that the fall of the spare seedling from the spare seedling mounting table 20 due to the bending can be prevented.

[0003]

However, according to the prior art described above, the spare seedling rest is made heavy by forming the spare seedling rest with a resin molded product in which a metal core is embedded. Since the cost is increased, there is room for improvement in reducing the weight and production cost of a rice transplanter equipped with a large number of spare seedling mounting stands.

SUMMARY OF THE INVENTION An object of the present invention is to provide a lightweight and inexpensive structure while securing rigidity capable of preventing the occurrence of bending which may occur when a spare seedling is placed because it is mounted in a cantilever manner. It is an object of the present invention to provide a spare seedling mounting table suitable for reducing the weight and production cost of a rice transplanter.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, a column which is erected on a traveling body extends laterally outward from the column. In a spare seedling mounting table of a rice transplanter mounted in a cantilever manner, a vertical rib for connecting a column disposed on a base end side connected to the column, and extending laterally outward from the vertical rib. The main rib and a reinforcing rib extending from a base end portion of the main rib to a front and rear portion of the vertical rib with respect to the main rib are integrally formed of a resin molded product.

According to the first aspect of the present invention, while the spare seedling mounting table is formed of a resin molded product, it extends laterally outward from the vertical rib for connecting the column. Due to the main ribs provided, the rigidity against the bending that is greatly displaced downward toward the extended end side, which may occur when the preliminary seedling is placed because it is mounted in a cantilever manner, The reinforcing ribs extending from the base end portion of the main ribs to the front and rear portions of the longitudinal ribs with respect to the main ribs, cantileverly attach to the support pillars, thereby concentrating the weight of the spare seedlings. The rigidity against the deflection on the side is further increased. That is, even without embedding a metal core material, the rigidity of the spare seedling mounting table against the bending can be effectively increased, and
Since the bending can be prevented from occurring when the spare seedling is placed, the spare seedling can be prevented from dropping from the spare seedling mounting table due to the bending, even though the spare seedling is mounted on the spare seedling. Become like In addition, since there is no need to embed a metal core, the spare seedling mounting table can be constructed at a low weight and at a low cost.
It is possible to reduce the weight and production cost of a rice transplanter equipped with a large number of spare seedling platforms.

[Effect] Therefore, the structure is lightweight and inexpensive, while securing rigidity that can prevent the occurrence of bending that may occur when a spare seedling is placed because it is mounted in a cantilever shape. Thus, it is possible to provide a spare seedling mounting table suitable for reducing the weight and manufacturing cost of a rice transplanter.

According to the second aspect of the present invention,
2. The drainage part according to claim 1, wherein the drainage part is a grid-shaped drainage part provided in a central part and a base end portion of a horizontal rail of the drainage part along the left-right direction of the traveling body. And a reinforcing rib extending over the front and rear portions of the peripheral wall with respect to the base end side portion of the horizontal rail.

According to the second aspect of the present invention, the drainage portion for dropping water and mud from the spare seedlings is formed at the center of the spare seedling rest to further increase the spare seedling rest. Despite being lightweight, the drainage part is formed in a lattice shape with a horizontal rail and a peripheral wall along the left and right direction of the traveling machine, and at the base end side of the drainage part where the weight of the spare seedlings is concentrated. Since the reinforcing ribs extend from the horizontal rail of the drainage part to the front and rear parts of the horizontal rail on the peripheral wall of the drainage part, the preliminary seedlings are placed because they are cantilevered. In this case, it is possible to secure the rigidity against the bending that may occur at the time.

[Effect] Accordingly, the weight can be further reduced while securing rigidity capable of preventing the occurrence of bending which may occur when the spare seedling is placed because the cantilever is attached so as to be mounted. It is possible to provide a spare seedling mounting table more suitable for reducing the weight of the rice transplanter.
