DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling storage box used for transporting crop seedlings such as rush seedlings and transferring crop seedlings to a seedling cradle of a seedling transplanter. The present invention relates to an apparatus for packing crops and seedlings into which boxes are packed.

[0002]

2. Description of the Related Art For example, in the case of rush seedlings, an operator separates a mother plant grown from a seed stock into approximately one rush seedling for planting, either manually or by using a stocking device. The separated rush plants were manually packed into the seedling storage box.

[0003]

Since the operation of packing the separated seedlings into the seedling storage box as described above is very time-consuming and requires a large amount of labor, the efficiency of the pre-processing work for the planting operation is improved. In view of this, automation of the operation of packing crop seedlings into a seedling storage box is desired. If there is variation in the packing condition (density) of crop seedlings in the seedling storage box,
Even after the transfer of the crop seedlings to the seedling rest of the seedling transplanter, the degree of packing (density) of the crop seedlings at the seedling rest remains uneven. In some cases, a plant may be formed, or the number of plant seedlings planted may vary. An object of the present invention is to provide a box for packing seedlings that can be packed in seedling storage boxes without any variation in the degree (density) of the seedlings and without damaging the seedlings.

[0004]

A feature of the present invention resides in that a boxing apparatus for crop seedlings is configured as follows. A feeding mechanism that feeds the crop seedlings into the seedling storage box in a standing position with the root part down, and the crop seedlings fed into the seedling storage box from the crop seedling delivery section of the feeding mechanism are placed on the predetermined wall side of the seedling storage box. A pressing mechanism for pressing the head and a supporting mechanism for movably supporting the seedling storage box along the pressing direction of the pressing mechanism, the crop seedling sent to the seedling storage box in a standing position with the root part down. By pressing the seedling storage box along the pressing direction by pressing the seedling storage box toward a predetermined wall portion by the pressing mechanism, the crop seedlings are packed in the seedling storage box while moving the seedling storage box along the pressing direction. At a feeding start position of the seedling storage box when the crop seedlings are sent to the seedling storage box, a predetermined distance from a predetermined wall portion of the seedling storage box at the sending start position along the direction in which the crop seedlings are fed into the seedling storage box. Seedlings only at a distance While vertical movement of the top of the crop seedlings fed into pay box are provided with a seedling pushing member aligned by pressing.

[0005]

[I] According to the feature of the first aspect, the seedling is fed into the seedling storage box by the feeding mechanism in a standing posture with the root part down, and the crop seedling sent to the seedling storage box is pressed by the pressing mechanism. The seedling storage box is pressed toward a predetermined wall.
Thereby, when the crop seedling first sent to the seedling storage box reaches a predetermined wall portion of the seedling storage box, the subsequent feeding of the crop seedling to the seedling storage box, and the pressing of the crop seedling by the pressing mechanism, A predetermined wall portion of the seedling storage box is pressed via the crop seedling, and the seedling storage box moves along the pressing direction of the pressing mechanism. Therefore, between the predetermined wall portion of the seedling storage box and the pressing mechanism, the crop seedlings in the seedling storage box are compressed to have a substantially uniform density, and the seedling storage box is moved along the pressing direction of the pressing mechanism. As they move, the seedlings are packed in the seedling storage box.

[II] As described in the preceding item [I], when the seedlings are fed into the seedling storage box by the feeding mechanism in a standing posture with the root part down, the seedlings are lifted from the other seedlings. Crop seedlings may be sent to the seedling storage box. As a result, when the crop seedlings are transferred to the seedling cradle of the seedling transplanter and planting work is carried out with the raised crop seedlings, the raised crop seedlings cannot be planted well, and May occur.

According to the first aspect of the present invention, the upper part of the seedlings fed into the seedling storage box is pressed and aligned by the seedling pressing member which moves up and down. When the seedlings are sent to the seedling storage box in a standing posture, even if there are raised seedlings, the raised seedlings are pressed by the seedling pressing member and aligned with other seedlings.

[III] In the case where the seedling pressing member as described in the above item [II] is provided, when the seedling storage box is still packed with a small amount of crop seedlings, the state is said that the crop seedlings push each other. Instead, the crop seedlings are relatively easy to move.In such a state, when the upper part of the crop seedlings sent to the seedling storage box is pressed by the vertically moving seedling pressing member, the crop seedlings are conversely moved. It is conceivable that they move and fall, or the stems of the crop seedlings break.

According to the first aspect of the present invention, the seedling is pressed from a predetermined wall portion of the seedling storage box at the initial feeding start position to a position separated by a predetermined distance along the direction in which the crop seedling is fed into the seedling storage box. Since the members are arranged, when the seedling storage box is located at the first feeding start position, when the first crop seedling is sent to the seedling storage box, a predetermined wall portion of the seedling storage box is pressed against the seedling. It is not located below the member. As a result, when the seedling storage box is still packed with a small amount of crop seedlings, as in the case where the first crop seedling has been sent to the seedling storage box, the crop sent to the seedling storage box by the seedling pressing member is Since the upper part of the seedling is not pressed, a certain amount of crop seedling is packed in the seedling storage box, and when the predetermined wall portion of the seedling storage box reaches below the seedling pressing member by moving the seedling storage box. Then, the upper part of the crop seedling sent into the seedling storage box by the seedling pressing member starts to be pressed.

[0010]

According to the first aspect of the present invention, it is possible to obtain an apparatus for packing crop seedlings into the seedling storage box at a substantially uniform density. It is now possible to prevent the harmful effects of not being packed (such as occurrence of missing stocks during planting work and variation in the number of plant seedlings planted). Thereby, the planting accuracy of the crop seedling by the seedling transplanter could be improved.

According to the first aspect of the present invention, since the seedling pressing member is provided for pressing the upper portion of the raised crop seedling to align it with another crop seedling, the raised crop seedling cannot be planted properly in the seedling transplanter. Can be prevented beforehand, and the planting accuracy of the crop seedling by the seedling transplanter can be further improved. In this case, when the seedling storage box is still packed with a small amount of crop seedlings, the upper part of the crop seedling sent to the seedling storage box is not pressed by the seedling pressing member, so that the seedling pressing member can be It was possible to avoid the situation where the seedlings moved and fell or the stems of the crop seedlings broke. As a result, it is possible to appropriately align the raised seedlings with other seedlings without disturbing or damaging the seedlings, thereby further improving the planting accuracy and yield of the seedlings by the seedling transplanter. Could be improved.
