A soil filling device for supplying soil to the seedling box on the transport mechanism, and a soil replenishing device for lifting the soil and replenishing the soil from the upper portion with respect to the soil filling device. A lifting conveyor device as disclosed in Japanese Patent Application Laid-Open No. 2-1255 is used. This soil replenishing device has a lower soil replenishing unit, and a lifting conveyor mechanism that scoops and lifts the soil of the soil replenishing unit, and supplies the soil from the upper portion to the soil replenishing device. By replenishing the soil, the soil can be continuously supplied to a large number of seedling boxes transported by the transport mechanism.

[0003]

In the above-mentioned prior art, all of the soil replenishment to the soil replenishment section must be performed artificially. In addition, the recovery of the soil falling from the soil replenishment device and the use of the soil replenishment device are not required. If there is a soil leveling mechanism on the lower side in the transport direction, the soil falling from the soil leveling mechanism must be collected separately, so collecting and reusing the fallen soil is very troublesome, and work efficiency Is causing the decline. The present invention is configured such that the soil falling from the soil filling device side is collected below and supplied to the soil replenishing unit of the soil replenishing device, so that the collected soil and the reuse thereof can be extremely reduced. It is an object of the present invention to provide a soil supply system that can be made simple and work efficiency can be improved.
