Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling placing table on which seedlings to be planted are placed together with a seedling raising sheet, and a sheet collecting device for taking out and collecting the seedling raising sheet from the seedling placing surface side to the backside of the seedling placing table. The present invention relates to a seedling planting device equipped with a seedling planting claw for taking out a seedling to be planted from the seedling platform.

[0002]

2. Description of the Related Art Conventionally, the seedling planting apparatus has been constructed as shown in, for example, Japanese Patent Laid-Open No. 189609/1982. That is, a frame body is provided which is arranged on the back side of the seedling placing table and is connected to the seedling placing table, and the frame body receives and stores the seedling raising sheet taken out from the seedling placing surface side of the seedling placing table to the back side. By configuring
The seedling-raising seedlings, which had become empty after the planting seedlings had been separated, were collected and stored on the back side of the seedling mount.

[0003]

Conventionally, when taking out the collected seedling-growing sheet, it was necessary to put a hand behind the seedling-placing table and take out the seedling-growing sheet directly from the collection place. Therefore, when taking out a large number of seedling-growing sheets, it is necessary to take them out in small amounts, which is troublesome. In particular, in the case of a seedling planting apparatus with a large number of planting lines, it takes a lot of time and labor to take out the seedling raising sheet because it is collected from a plurality of rows of seedling placing sections of the seedling placing table and stored in large numbers. Since the lateral width becomes long, it may be difficult to reach the central portion in the lateral direction and it may be difficult to take it out. An object of the present invention is to provide a seedling planting device that can relatively easily and quickly take out the collected seedling-growing sheet.

[0004]

In order to achieve the object, a seedling planting apparatus according to the present invention is the sheet collecting container for storing the seedling-growing sheet taken out on the back side of the seedling placing table in the above-mentioned one. , And that the sheet collecting device is provided with a support rail for supporting the sheet collecting container at a sheet collecting position on the rear surface side of the seedling placing table and operably supporting the sheet collecting container to the outside of the seedling placing table from the sheet collecting place. Characterize.

The sheet collecting container may be constructed so as to be drawn out to the upper end side of the seedling mounting table, but it is advantageous as follows when the structure according to claim 2 is adopted.

[0006]

[Function] When the sheet collection container is pulled out, the seedling raising sheet comes out into the sheet collection container. Even if a large number of nursery sheets are stored, they will be put together in a sheet collection container and will be released at once. In addition, the size of the sheet collection container in the lateral direction of the seedling mounting table is set so as to cover the multiple seedling mounting sections of the seedling mounting table, and one sheet collection container is used to grow seedlings from multiple rows of seedling mounting sections. The sheets are collectively collected. Then, even if the number of planting rows is large and many seedling raising sheets are collected, and even if the width of the seedling placing base is large and it is difficult to reach the center side of the seedling placing table, one sheet collecting container can collect seedling raising sheets for multiple rows. It becomes possible to take out all at once, and the nursery sheet collected at the center side of the seedling placing table can be taken out together with the nursery sheet collected at other places.

When the structure according to the second aspect is adopted, the sheet collecting container is pulled out from the lateral outside of the seedling placing table or is returned and stored. Then, as compared with the case where the seedling placing table is pulled out toward the upper end side, the seedling raising sheet can be taken out and the pulled-out sheet collecting container can be returned in a stable state at a low level.

[0008]

[Effects of the Invention] Regardless of the number of seedling-growing sheets to be taken out, it was possible to easily and quickly take out the sheets by simply pulling out the sheet collection container. Further, even when many seedling-raising sheets are collected due to a large number of planting rows or a hard-to-reach part is formed, it is possible to similarly and easily take out the seedling-raising sheets.

When the construction according to claim 2 is adopted, the sheet collection container can be stably taken in and out at a low level position, so that the sheet can be taken out easily from this aspect as well, and the returning operation of the collection container can be facilitated. .
