Abstract

PURPOSE:To provide a preliminary seedling reservoir designed to use lighter and smaller support poles and advantageously holding a preliminary seedling table on the poles. CONSTITUTION:A support pole connecting rod 13 is connected from the upper end of one party of a pair of left and right support poles 12, 12 to that of the other party. Thereby, both the upper ends are mutually supported through the connecting rod 13 and even if the support rod 12 is intended to be lighter and smaller, it presents relatively excellent support strength. The connecting parts 13a, 13b for the respective support poles 12 to the connecting rod 13 are provided with stopper parts on the lower end surfaces. These stopper parts make pressing action on the 1st connecting parts 15a of the subsupport pole connecting rods 15 respectively attached to the support poles 12 and therefore also make pressing action on the 1st attaching parts 16 of preliminary seedling tables 10, 11 attached to the respective support poles 12, thus suppressing the vertical motion of the tables 10, 11 relative to the support poles 12. Thereby, the connecting rod 13 serves as a stopper for the tables 10, 11, thus fixing the tables 10, 11 so as to be hard to vertically slip.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with a pair of columns that stand on the left and right sides of a traveling body separately, and a plurality of preliminary seedling mounts that are attached to the pair of columns in a plurality of upper and lower stages. Of the above-mentioned preliminary seedling placing bases each having a mounting portion fitted to the support from the upper end side, to a preliminary seedling storage device for a riding type rice transplanter.

[0002]

2. Description of the Related Art In the above-mentioned preliminary seedling storage device, since the mounting portion of the preliminary seedling mounting base is fitted onto the support pillar from the upper end side, the preliminary seedling mounting base is mounted on the support pillar. When planting low-height seedlings, such as seedlings, adjust so that a large number of spare seedlings can be stored for the length of the support, and when planting high-health seedlings such as adult seedlings. It is possible to adjust the reserve seedlings so that the seedlings do not bend. That is, preparing a seedling stand with a different length of attachment part,
Prepare a spacer to be fitted on the support column by sandwiching it between the attachment parts of the preliminary seedling placing table. In the case of a seedling with a low height, a spare seedling mount with a short mounting portion is selected and attached to a support, or only the spare seedling mount is attached without using a spacer. Then, the space between the preliminary seedling mounting bases becomes small, and as many spare seedling mounting bases as possible can be attached to the columns. For seedlings with a high height, select a spare seedling stand with a long attachment part and attach it to a support, or attach a spare seedling stand using a spacer.
Then, the space between the preliminary seedling mounting bases becomes large, and even if the seedlings are mounted on the preliminary seedling mounting base, the seedlings do not hit the preliminary seedling mounting base that is one step higher, so that it does not bend significantly when hit. Become. As the seedling preliminary seedling storage device, conventionally, for example, as shown in Japanese Utility Model Laid-Open No. Sho 56-75821, the props are supported only on the lower end side connecting to the machine body.

[0003]

Conventionally, when the number of stages of the preliminary seedling placing table is increased, it is necessary to increase the length of the support column to increase the strength of the support column. Therefore, it is necessary to increase the size of the support column by making it larger. was there. An object of the present invention is to make it possible to employ a comparatively light and small strut for the number of stages of the seedling placing base, and to use the structure for that purpose for stopping the movement of the preliminary seedling placing base.

[0004]

In order to achieve the object of the present invention, there is provided a preliminary seedling storage device for a riding type rice transplanter according to the present invention.
In the one described at the beginning, a pair of strut connecting rods that are connected over one upper end portion of the pair of strut and the other upper end portion are provided, and a pair of strut connecting rods are separately connected to the pair of strut rods of the strut connecting rod. Each of the connecting portions is provided with a stopper portion that presses the attaching portion of the preliminary seedling placing base of the uppermost column of the pillar to regulate the vertical movement of the preliminary seedling placing base with respect to the strut.

Although the preliminary seedling placing base may be constructed so as to be connected to the pillar in a non-rotatable manner, the construction according to claim 2 is advantageous as follows.

[0006]

The strut connecting rod connects the upper ends of the pair of strut to each other so that the pair of strut supports each other through the strut connecting rod. As a result, even with a strut that has the same strength as the conventional strut without the support on the upper end side,
It is supported on both the upper end side and the lower end side, so that it is possible to support a larger number of preliminary seedling placing stands than the conventional columns. When the strut connecting rod is connected to the strut, the stopper portion of the strut connecting rod presses the attachment portion of the uppermost preliminary seedling placing base to regulate the vertical movement of the preliminary seedling placing base with respect to the strut. Then, the auxiliary seedling mounting bases on the uppermost stage also press all the spare seedling mounting bases below this, and the vertical movement of all the spare seedling mounting bases with respect to the columns is regulated. As a result, a stopper mechanism is provided on each of the preliminary seedling mounting bases,
Even if the special stopper mechanism is not installed between the top seedling stand and the rod connecting rod, the stand can be fixed to the stand.

When the construction according to claim 2 is adopted, when the mounting position of the sub-column is adjusted with respect to the column, all the preliminary seedling mounting bases rotate together with the sub-column with respect to the column when the sub-column rotates. When the auxiliary columns are in the predetermined adjustment position and fixed to the columns, all the preliminary seedling placing bases are fixed to the columns via the auxiliary columns so as not to rotate.

[0008]

EFFECTS OF THE INVENTION Since the upper ends of the columns are supported by the column connecting rods so that the columns can be made lighter, further, the column connecting rods are used to prevent movement of the preliminary seedling placing table with respect to the columns. By making use of the special stopper mechanism unnecessary, the column can be made lighter, and the special stopper mechanism can be omitted to reduce the weight and cost.

When the structure according to claim 2 is adopted, since all the preliminary seedling placing bases can be rotationally adjusted by adjusting the mounting positions of the auxiliary columns, the mounting positions of the auxiliary columns are adjusted when the preliminary seedlings are loaded or unloaded. By performing a simple operation, it becomes possible to easily and efficiently perform loading and unloading work by adjusting the positions of all the preliminary seedling loading bases to the predetermined seedling loading position and seedling unloading position all at once.
