Description

The present invention relates to a seedling box and an apparatus for peeling a seedling box used for an operation of peeling a seedling of rice grown in the seedling box from a seedbed.

Conventionally, rice seedlings to be planted at the time of rice planting are cultivated by placing the cultivated soil in a seedling box, seeding the cultivated soil with seed potatoes, and placing the prepared seedling boxes on a nursery in a house or the like . And when it grows up to the extent necessary for rice planting, it peels off the nursery box from the nursery and carries it to the rice field.

However, since this seedling box has a plurality of small holes drilled in the bottom plate to improve drainage, the seedling stretches the roots from the holes into the ground during growing and stretches the roots. For this reason, the work of directly grabbing the seedling box that has become heavier with cultivated soil and peeled it off the seedbed by hand is a heavy labor, and it involves a burden on the waist and fingers of the hand.

Therefore, for example, measures such as laying a sheet with a plurality of holes on the bottom plate or the seedbed of the nursery box to suppress the root of the seedling from being rooted in the ground are taken. However, because of the recent depopulation of rural areas, these measures have been taken, but it is a small number of people to remove many seedling boxes rooted in the ground from the nursery. The burden per person is also increased. In addition, the aging of farmers is progressing, and there is a need for further facilitation and reduction of the work of peeling the nursery box from the nursery.

Various proposals have been made for these problems (for example, Patent Document 1).
