Description

[Detailed description of the invention] "Industrial application field" This invention forms a seeding bed by laying a foam bed material (substitute material for bed soil) inside a seeding box, and at the same time, seeds are placed on the top surface of the foam bed material. It relates to a seeding device for sowing.

``Prior Art'' Conventionally, as shown in Japanese Patent Application Laid-Open No. 60-54606, a foam bed material formed into a flat plate is placed inside a seeding box as a substitute for bed soil, and the foam bed material is watered to grow vegetables or vegetables. The technology for sowing grain seeds was developed.

"Problem to be solved by the invention" The above-mentioned conventional technology compresses the foamed bedding material in the seeding box conveyed by guide rolls with a pressure roller, and supplies water to the foamed bedding material that is restored at the rear of the roller. Since the foamed bedding material was partially compressed by the pressure roller, the foamed bedding material was easily displaced or deformed within the seeding box, and the foamed bedding material partially jumped out of the seeding box. There have been problems such as the need to prevent problems such as bulging and the like, as well as the need to prevent the sowing box from moving in a meandering manner when pressed by the pressure roller.

"Means for Solving the Problems" However, the present invention provides a seeding device that inserts a water-absorbent and flexible foam bed material into a seeding box and sows seeds on the upper surface of the foam bed material. A floor material soaking means is provided which compresses substantially the entire bed material from the upper surface side substantially simultaneously and supplies water substantially simultaneously to the substantially entire surface when restoring the foam bed material, and the floor material soaking means is moved into and out of the seeding box. The present invention is characterized in that substantially the entire foamed flooring material is compressed and restored at the same time and submerged in water.

"Action" Therefore, the entire foam flooring material is compressed at the same time,
Because water is supplied to the entire foam flooring at the same time during restoration,
It is possible to prevent displacement or deformation of the foam flooring material more easily than before, and the removal of air and water infiltration from the foam flooring material can be performed extremely uniformly and efficiently by one compression and restoration, and the foam floor material can be easily prevented from shifting or deforming. Easily prevents the seeding box from shifting due to water immersion work, and improves the workability of soaking foam flooring materials in water and improving the workability of sowing seeds on the top surface of foamed flooring materials compared to conventional methods. It is possible.
