Abstract
This study addresses the challenges of low mechanization, high labor intensity, and low efficiency in pineapple harvesting by designing a fully automated pineapple harvester aimed at achieving automation and enhanced efficiency in the harvesting process. Based on an analysis of pineapple growth characteristics, cultivation patterns, and existing harvesting equipment, an integrated solution is proposed encompassing upright positioning, multi-stage cutting with synchronous belt transmission, lifting and conveying mechanisms, and fruit collection systems. The design process defines the operational principles and key parameters of each subsystem, accompanied by comprehensive 3D modeling. The machine adopts a hybrid hydraulic-mechanical transmission system, offering high efficiency and minimal fruit damage, while ensuring adaptability to the complex field conditions of pineapple plantations. Cost analysis indicates that the device holds considerable economic benefits and significant market potential. This research provides a practical solution for the mechanization of pineapple harvesting, contributing to reduced labor demands, improved harvesting efficiency, and the sustainable development of the pineapple industry.
