Description

Technical Field

[0002] As the urbanization process continues to accelerate, the traditional agricultural production model faces many challenges, such as limited land resources and polluted production environment. In recent years, researchers and agricultural companies have been constantly exploring new urban agricultural production methods. Three-dimensional planting and plant factories have to a certain extent solved the needs of urban residents for healthy and green food, but most of the existing devices are fixed-type stacked planting devices, which are more suitable for large-scale and unified planting of a single plant in plant factories.

[0003] In recent years, modern agricultural science popularization, leisure agricultural landscaping, urban center agricultural micro-landscape exhibitions, primary and secondary school campus labor education, and university scientific research have put forward the same demand for plant planting device models, that is, to meet the needs of planting multiple crops at the same time with one device in a limited space. In the prior art, there are rotating functions integrated into three-dimensional planting devices, such as patent CN207560900 U proposes a rotatable and fixable plant planting device, but its size is large and not beautiful enough. Patent CN209897750 U integrates the intelligent control system into the multifunctional planting rotation system and improves the utilization rate of light energy by plants, but these devices still cannot meet the needs of planting different plants at the same time.

This device can meet the planting requirements of different space heights while planting multiple plants in a limited space. At the same time, it can integrate multiple functions such as plant production, viewing, teaching and scientific research. Summary of the invention
