Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an extension seedling placing table suitable for a straw transplanter.

[0002]

2. Description of the Related Art For example, in a rice seedling placing table for paddy rice planting machines, a shelf-like extended seedling placing table is provided on the back surface of the upper end of the seedling placing table and slid back and forth along the surface direction of the seedling placing table. , And the entire length of the seedling stand was expanded and contracted. Depending on the amount of remaining seedlings at the time of seedling supply, the mat seedlings may not be able to fit on the seedling placing table, and in such a case the extended seedling placing table can be pulled out and the mat seedling end part can be placed. There is.

[0003]

On the other hand, for supplying seedlings to the strawberry planter, a seedling box having a predetermined amount of strawberries is placed on the seedling stand, and then the side wall below the seedling box is opened to open the strawberries. Although only the seedlings are transferred to the seedling placing table, the strawberries in the seedling box may not be placed on the seedling placing table depending on the amount of the remaining seedlings, as in the case of the rice transplanter.
Therefore, it is planned to equip the straw plant transplanter with an extended seedling placing base, but it is difficult to adopt a structure in which the above-mentioned shelf-like extended seedling placing base is provided on the rear surface of the seedling placing base so as to be able to move in and out.

Because the mat seedlings have a surface shape in which the seedlings are connected to each other by the soil, it is sufficient that the matting seedlings are simply put on a shelf. In addition to falling on the extended seedling mounting table,
Side walls are also required to prevent it from falling sideways. Therefore, if the extended seedling mounting base is configured with the bottom surface and the left and right side walls, in this case, there is a problem that the structure of the rear side of the seedling mounting base cannot be slidably retracted due to the height of the side wall. , Further improvement is needed. An object of the present invention is to realize an extended seedling placing table of a straw transplanter, which works well without falling or falling of straw seedlings which are rose seedlings, and which can be stored when unnecessary, without realizing the above inconvenience. It is in.

[0005]

[Means for Solving the Problems] To achieve the above object, the present invention provides an extended seedling mounting base for mounting an extended seedling mounting base having a bottom surface for mounting seedlings and left and right side walls on the upper end of the seedling mounting base. To
This is the seedling supply posture with the top of the seedling placing table connected,
The present invention is characterized in that the posture can be freely changed from the seedling supply posture to the storage posture moved downward so as to be positioned in the empty space on the rear side of the seedling placing table.

[0006]

Describing with reference to FIG. 1, since the lower rear end of the extended seedling mounting base 7 and the lower front end of the seedling mounting base 4 are pivotally attached at the horizontal axis P, they are pivoted downward when not in use. It moves and stores in the back position of the upper part of the seedling stand 4. In this stored posture, the extended side wall 7b projects forward. During use, the extension bottom surface 7a is moved upward so that the extension bottom surface 7a is in the seedling supply posture along the mounting surface 4c of the seedling mounting base 4. With this pivotal structure, even if the extended side wall 7b exists, the seedling feeding posture can be achieved without a step between the extended bottom surface 7a and the placing surface 4c, and the seedling can be stored without any trouble.

Further, L-shaped rails are attached to the left and right of the upper part of the seedling placing table 4, and rollers which are movably engaged with the rails are provided above and below the lower end of the extension seedling placing table so that the seedling feeding posture can be adjusted by rolling. It may be configured so that it can be freely changed to the storage posture. In other words, the extended seedling placing base is placed in a seedling feeding posture in a state where the extended seedling placing base is continuously provided on the upper end of the seedling placing base and in a storage posture in which the extended seedling placing base is moved downward from the seedling feeding posture so as to be located in the empty space on the rear side of the seedling placing base. By making it configurable,
Even if the height of the side wall is high, it can be installed freely without impairing the seedling support function.

[0008]

[Effects of the Invention] Therefore, while using the extended seedling mounting base having a bottom surface and left and right side walls suitable for mounting rose seedlings, which are rose seedlings,
It was possible to provide the seedlings with a position suitable for a seedling feeding posture without causing a step difference on the seedling mounting surface and a storage posture without any hindrance, and it was possible to provide a suitable plant for a strawberry transplanter.
