[0001] [Cross-reference with related applications]

[0002] This application claims the benefit of priority from Korean Patent Application No. 10-2023-0105808, filed August 11, 2023, the entire contents of which are incorporated herein by reference.

[0003] The present invention relates to a hub rack and a plant treatment system including the same.

[0004] In order to automate the transport of plants to the cultivation tray or cultivation bed (tank) where plants are planted and grown, conveyors or chains were used to transport the plants. However, when using such equipment, the initial investment cost for the mechanical equipment is very high.

[0005] When using a method of transporting plants by robots such as AMR / AGV without using a conveyor or chain, an intermediate holding space (buffer space) is required to store the plants before harvesting or transplanting the transported cultivation tray / cultivation bed (tank) or performing other post-processing operations on the plants.

[0006] This intermediate space can be placed between the space where the plants are planted and the space where the plants are post-treated. However, the cultivation space where the plants are planted is vulnerable to pests and diseases, so it needs to be isolated from the outside space.

[0007] Additionally, because the growing trays stored in these buffer spaces contain plants whose roots retain nutrients, managing the water (nutrient solution) dripping from the roots is crucial. If nutrient solution drips onto the plants below, the plants' marketability may decline.

[0008] The background technology described above is technology that the inventor possessed or acquired in the process of deriving the disclosure of the present application, and cannot necessarily be said to be publicly known technology disclosed to the general public prior to the present application.
