Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a device for loading seedling boxes, and more particularly, to a device for loading seedling boxes in which seedlings have been germinated in a stacked state onto a seedling growing shelf for greening.

[Conventional technology]

In order to increase the number of seedling boxes that can be installed in a limited germination space or to improve heat retention, germination is performed by stacking seedling boxes, and the greening of the germinated seedlings is achieved by arranging the seedling boxes one above the other. When planting seedlings in the installed state, it is necessary to allow light to enter each seedling box during greening, so after the germination period is over, place the stacked seedling boxes between the upper and lower boxes. It is necessary to load the seedlings onto the greening seedling racks where the seedling boxes can be placed so that there is a gap. Conventionally, this loading was done manually, which had the following disadvantages.

[Problem that the invention seeks to solve]

That is, it is necessary to take out the seedling growing boxes from the piled-up group of seedling growing boxes and move them to the greening seedling raising shelf, which not only increases the required labor but also reduces the efficiency of the loading work.

An object of the present invention is to provide a loading device which can easily, reliably and efficiently load stacked and germinated seedling boxes onto a seedling raising rack for greening, and which can be done safely and with as simple a structure as possible.

[Means for solving problems]

The seedling box loading device according to the present invention includes a seedling box lifting mechanism that lifts and holds the topmost seedling box from a group of stacked seedling boxes, and a seedling box lifting mechanism that moves the front shelf for greening up and down with respect to the seedling box lifting mechanism. and a seedling box pushing mechanism for pushing out the seedling box lifting mechanism from the seedling box lifting mechanism and placing it on the seedling growing shelf for greening, and comprising a lifting tool support member to constitute the seedling box lifting mechanism. , is provided so that it can be raised and lowered with respect to the seedling raising box, and is rotatable around the axes in the longitudinal direction and the lateral r1 direction of the seedling raising box, and is attached to the upper end of the seedling raising box. The lifting tool supporting member is provided with an abutting portion that makes the lifting tool supporting member parallel or almost parallel to the seedling growing box by swinging around the axis, and the lifting tool is in an action state and an action released state with respect to the seedling growing box. It is characterized in that it is attached to the lifting tool support member so as to be switchable between the two, and its functions and effects are as follows.

[For production]

By operating each mechanism so that it operates as desired, or by starting the mechanism so that it is automatically driven, the seedling box lifting mechanism lifts the seedlings in the top row of the group of seedling boxes. As the box is lifted and held,
The seedling raising shelf for greening is operated by the lift mechanism so that the holding seedling raising box and the shelf part on which it is to be loaded are aligned, and the seedling raising box held by the raising mechanism for raising seedlings is moved onto the raising shelf for greening by the pushing mechanism for raising seedlings. loaded.

Even if the stacked seedling growing boxes are tilted due to the lifting force of the germinated seedlings, as the lifting tool support member descends and contacts the top seedling growing box, the abutting portion and rotation Because of the dynamic configuration, the seedling box automatically assumes a parallel or nearly parallel posture regardless of its inclination, and the lifting tool operated in the operating state reliably acts on the seedling box as specified regardless of its inclination. do.

〔Effect of the invention〕

Taking out seedling boxes from a group of seedling boxes and loading them onto the greening seedling rack can be done easily by simply operating and starting each mechanism, and each mechanism can be operated more efficiently. It is now possible to improve the productivity of seedlings.

Even in the case of seedling boxes that have a structure that engages each other so that they do not collapse even when stacked, the holding structure is used. Regardless of the situation, the seedling box can now be taken out safely without collapsing.

Even if the seedling growing box is tilted, the lifting tool acts on the seedling growing box reliably, making it possible to take out the seedling growing box from a group of growing boxes without making mistakes, and loading work can be done reliably without making any mistakes. Ta.

Since the automatic posture adjustment of the lifting tool support member is performed by contact with the seedling box, the structure can be simplified so that sensors, actuators, and control circuits are not required compared to those that are required. , and by aligning the seedling box and the afforestation seedling shelf by raising and lowering the afforestation seedling shelf, compared to a structure in which the seedling box lifting mechanism moves up and down along the afforestation seedling shelf. Therefore, the structure can be simplified so that this elevating structure is not required, and the structure of the entire device can be made as simple as possible, making it economically advantageous.
