Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a nursery box feeder, a bed soil feeder, a seeding device, and a soil cover feeder in that order on a transport line for transporting a nursery box for rice seedling cultivation. It relates to a certain seeding plant.

[0002]

2. Description of the Related Art In the above seed plant,
Some are configured so that a seeding process for paddy rice and a seeding process for vegetables and flowers can be performed. In the seeding process for paddy rice, feeding of seedling raising boxes to the transport line, supply of bed soil to seedling raising boxes, seeding, and covering soil supply are automatically performed. Paddy rice seedlings are cultivated in a mat shape, whereas vegetable / flora seedlings are cultivated in a pot shape. Therefore, when performing the seeding process for vegetables / flowers, a mat shape is used. In the seedling raising box for paddy rice seedling cultivation formed to grow seedlings, a seedling raising tray for growing vegetables and flowers is formed in a state where multiple seedling pot parts are aligned vertically and horizontally to grow pot seedlings. It is designed to be placed. Conventionally, placing a seedling raising tray in a seedling raising box when performing a seeding process for vegetables and flowers has been performed manually.

[0003]

That is, according to the above-mentioned prior art, in the seeding process for paddy rice, the labor is reduced by automating the work, but the seeding process for vegetables and flowers is performed. However, there is room for improvement in order to reduce labor because it is necessary to manually place the seedling raising tray in the seedling raising box during the seeding process for vegetables and flowers. It was

An object of the present invention is to reduce the labor in the seeding process for vegetables and flowers by automating the operation of placing the seedling raising tray on the seedling raising box.

[0005]

In order to achieve the above object, in the first aspect of the present invention, a nursery box feeding device, a bed soil feeding device, a seeding device, and a seedling device are provided on a transport line for transporting a nursery box for paddy rice seedling cultivation. And, a soil covering supply device, in a seeding plant that is arranged in that order, between the seedling raising box feeding device and the bed soil feeding device, a seedling raising tray for cultivating vegetables and flowers for the seedling raising box. A seedling raising tray supply device was placed.

According to the second aspect of the present invention, in addition to the first aspect,
The bed soil supply device, the seeding device, and, while arranging the seedling raising box supply device on the floor above the floor where the soil covering supply device is arranged, the bed soil supply from the seedling raising box supply device to the seedling raising box A vertical transport device for vertically transporting the device, and a horizontal transport device for horizontally transporting from the floor soil supply device to the covering soil supply device via the seeding device, and the vertical transport device. The seedling raising tray supply device is configured such that the seedling raising tray is placed on the seedling raising box that is vertically conveyed.

[0007]

According to the first aspect of the present invention, in the seeding process for vegetables and flowers, the seedling raising tray feeding device disposed between the seedling raising box feeding device and the bed soil feeding device is used for the seedling raising tray. Will be placed. In other words, it is not necessary to manually place the seedling raising tray in the seedling raising box during the seeding process for vegetables and flowers.

According to the second aspect of the present invention, since the seeding plant is distributed on the two floors, the area occupied by the seeding plant on one floor can be reduced. Further, while adopting a vertical transfer device in a part of the transfer line, since the seedling-raising tray supply device is configured to place the seedling-raising tray on the seedling-raising box that is vertically transferred by the vertical transfer device, It is possible to effectively use the upper space of the floor in which the floor soil supplying device, the seeding device, and the soil covering supplying device are arranged. That is, the floor area occupied by the seeding plant can be reduced as compared with the case where the whole seeding plant is arranged on one floor.

[0009]

As described above, according to the first aspect of the present invention, since the operation of placing the seedling raising tray on the seedling raising box can be automated, the labor in the seeding process for vegetables and flowers can be reduced. It was

According to the second aspect of the present invention, the seeding plant is designed to reduce labor in the seeding process for vegetables and flowers by automating the operation of placing the seedling raising tray on the seedling raising box, The floor area occupied by the sowing plant can be made relatively small.
