Description
Technical Field
[0001] This utility model belongs to the field of agricultural greenhouse irrigation, specifically a retractable integrated robot for agricultural greenhouse planting. Background Technology
[0002] Modern greenhouses utilize integrated water and fertilizer systems, which have effectively improved traditional crop cultivation methods, especially for crops with specific growing requirements, solving the supply problems of vegetables during off-seasons and peak seasons. Despite continuous innovation in irrigation, fertilization, and pesticide application management of greenhouse crops, existing systems still face three main problems: First, traditional top-down irrigation methods cannot achieve comprehensive water supply, potentially leading to plant drying or death; second, row-wide spraying makes localized, precise management difficult, increasing the risk of pest infestations and costs; and finally, single-function nozzles cannot meet the integrated needs of water, fertilizer, and pesticide application, further increasing management costs.
[0003] In summary, this utility model provides a retractable integrated robot for agricultural greenhouse cultivation. By utilizing the retractable mechanism and a three-headed nozzle design that integrates water, fertilizer, and pesticide application, the reach of the nozzles is expanded to overcome the limitations of traditional management systems in the precise application of water, fertilizer, and pesticides and in the implementation of three-dimensional irrigation, thereby solving the aforementioned problems.
