Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a seedbed sheet manufacturing device that is capable of sowing a plurality of types of plant seeds in a predetermined combination pattern.

(Conventional technology) The provision of flower beds in urban development, parks, green spaces, and other areas is essential for providing a sense of beauty and moisture.

Conventionally, flower seeds are sown in the ground where flowers are to be grown, or seedlings are planted and allowed to grow.

(Problem to be solved by the invention) However, it is not easy to sow flower seeds in the ground over a vast area or to plant separately grown seedlings in a desired vegetation pattern. It is even more difficult to do so. Moreover, combining different types of flowers,
Growing a plurality of types of flowers in a predetermined pattern is increasingly difficult and requires a lot of work and labor.

In some cases, seeds of the same species are sown at a high density, such as grass seeds, on the surface of a sheet made of a material that corrodes or dissolves in the ground, such as mulch, and is then used as PVA. There is a type of grass that is fixed to a sheet with a water-soluble material such as (polyvinyl alcohol) and buried shallowly in the ground, making it possible to sow grass seeds over a wide area with high efficiency.

However, while this can achieve the goal when seeds of the same species are sown at high density, it is not suitable for plants that are regularly planted at regular intervals like flowers, and even more so when seeds of multiple species are sown. It is not possible to make each plant grow in a predetermined pattern based on the basolateral pattern.

This invention has been made in consideration of the above-mentioned circumstances, and is a seedbed sheet that can be manufactured with high efficiency on which multiple types of flowers or similar plants can be combined and planted in a predetermined pattern. The purpose is to provide manufacturing equipment.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a seeding belt having a seed holding means for holding plant seeds on the surface formed in accordance with a planned seeding pattern, and a seeding belt with axes parallel to each other. A plurality of sets of seed transfer devices are provided, each of which is provided with a seed supply means that is wound around the seed belt so as to be rotatably driven, and is provided with a seed supply means that scatters plant seeds onto the surface of this seeding belt and holds them in the seed holding means. Parts of the seeding belts of the devices are arranged and arranged in the conveyance direction of the conveyance path, facing the conveyance path of the seedbed base, and the pattern of the seed holding means formed on the seeding belt of each of the seed transfer devices is transferred to the seedbed base. A seedbed sheet is formed by transferring and fixing a plurality of plant seeds onto a seeding belt base sheet using a seeding pattern based on a combination of the patterns of these seed holding means.

(Function) When the seeding belt of each seed transfer device is not rotated and different types of seeds are scattered on the surface thereof from the seed supply means onto each seeding belt, the seeds are held by the seed holding means and are attached to each seeding belt. Each seed is held in a pattern on top. When these seeding belts come into contact with the seedbed bases that are fed along the conveyance path, the seeds held on the surface of the seeding belts are sequentially transferred onto the seedbed bases. Therefore, in addition to the seed pattern transferred by the previous seed transfer device, the seed pattern by the next seed transfer device is transferred, and a composite overall sowing pattern is formed by these seed patterns.

As a result, various patterns, letters, figures, etc. containing multiple types of plant seeds are formed on the seedbed base, and when the seedbed sheet obtained in this way is placed underground, each seed will germinate and create the above-mentioned pattern. Multiple types of plants are grown in the same arrangement as the sowing pattern.
