Design And Application Of Aeroponics Package Unit In Plant Factory

Aeroponics package unit which includes two modules:removable aeroponics equipment and transplantation&harvesting matching unit belongs to supporting facilities of plant factory. The view that plant factory represents the most advanced facility agriculture level has been acknowledged all around the world. By now several advanced agriculture production countries such as Japan, America have paid attention to plant factory researches. However, in China the researches of plant factory just started. The research of facilities of plant factory will not only meet the requirements of modern agriculture development, but also attract the public attention more and more.In order to improve utility rate of space and operation efficiency, design a kind of aeroponics package unit combining the project of artificial light plant factory technology integration. And the aeroponics package unit has been applied in the practice successfully.In the thesis, research contents and results are as follows:1. According to the requirements of aeroponics production, determine the design task of aeroponics package unit, including functional requirements, working process, and structure of each module.2. Elaborate the design process of the removable aeroponics equipment, including frame structure design and check, drive system design, model selection of AC servo motor and its control strategy.3. Finish the design of the transplantation&harvesting matching unit. In order to meet the requirement of small-scale production, design a kind of simple transplantation&harvesting matching unit. Discuss a more efficient transplantation&harvesting scheme, including the design of the key structure, at the same time.4. Research the dynamic behavior of the removable aeroponics equipment through the theoretical modal analysis and the experimental modal analysis. The analysis result and the site operation show that the parameters of the equipment are reasonable and the sympathetic vibration will not happen and the FEA modal can provide a reference for the design and optimization of the similar structure.
