Description

Feeding box loading device{APPARATUS FOR LOADING RAISING OF SEEDING BOX}

The present invention relates to a seedling box stacking device, and more particularly, to a seedling box stacking device capable of stacking seeded seedling boxes in multiple layers.

In general, a sowing machine is used to make it easy and accurate to sow and prepare seeds in the mock formed to cultivate rice crops used for rice farming, such as rice seeds for water supply, and field crops such as onions and green onions.

In the seeding machine, a seedling box is introduced to supply soil and seeds in the seedling box, and the seedling seedling box is discharged from the seeding plant and transferred to the germination site.

Korean Patent Registration No. 1039193 (hereinafter referred to as'prior art document') discloses a seedling box transfer device.

In the above prior art documents, the seedling boxes withdrawn one by one from the sowing machine and supplied to the loading frame are arranged in a certain amount in the loading frame by the movement control unit. Thereafter, the nursery boxes are moved to the transfer bed by the transfer transfer unit, and the discharge transfer unit is sequentially moved on the transfer frame as the transfer bed is pulled and transferred to the germination chamber.

At this time, the seedling boxes withdrawn one by one from the sowing machine are arranged and arranged in a plane on the loading frame, and then transferred.

In the seedling box transfer device disclosed in the prior art document, the seedling box drawn out from the seeding machine is transferred to the transfer frame in a state arranged in a single-layer structure on the loading frame and discharged. Therefore, in order to transfer the seedling box to the next process, there is a hassle of moving the seedling box one by one, so that the work process can proceed slowly. In addition, in order to list a certain number of nursery boxes on the loading frame, the loading frame must be provided in a certain area or more, so there is a disadvantage that a wide working space is required. In addition, since the seedling box is provided in a single layer structure on the loading frame, the utilization efficiency is remarkably lower than the large area of the loading frame, and thus there is a problem in that work efficiency and production efficiency are lowered. Therefore, a technique for solving the above problems is required.
