吊栽木耳采摘机设计与试验OA

Edible fungi are commonly cultivated using either ground-based or hanging cultivation systems.While mechanized harvesting technologies have been developed for ground-cultivated fungi,efficient harvesting equipment for hanging-cultivated fungi remains largely unavailable.To address this gap,a harvesting machine specifically designed for hanging-cultivated edible fungi was developed and evaluated.The machine was designed and modeled using SolidWorks software,and finite element analysis was conducted to assess and optimize the strength and structural performance of the transmission gear system.To evaluate harvesting performance,motor speed,scraper deflection angle,and the spacing between the fungus stick and the scraper were selected as experimental factors.The clean harvesting rate and fruiting-body damage rate were used as performance indexes.Single-factor experiments and multi-factor response surface experiments were conducted using a prototype machine,and the experimental data were analyzed and optimized using Design—Expert 13.0 software.The results showed that the effects of the tested factors on the ear picking rate,in descending order,was:spacing between the fungus sticks and scraper,scraper deflection angle,and motor speed.For the fruiting-body damage rate,the order of influence was:motor speed,scraper deflection angle,and spacing between the fungus sticks and scraper.The optimal parameter combination was determined to be a motor speed of 900 r/min,a scraper deflection angle of 10°,and a spacing of 80 mm between the cultivation stick and the scraper.Under these conditions,the clean harvesting rate reached 93.87%,while the fruiting-body damage rate was only 2.12%.Validation experiments conducted using the optimized parameter combination produced results that closely matched the predicted values,confirming the reliability of the optimization model.The developed harvesting machine demonstrates excellent harvesting performance and provides a practical solution for the mechanized harvesting of hanging-cultivated edible fungi.The findings of this study offer valuable theoretical support and technical guidance for the development and application of intelligent harvesting equipment in the edible fungus industry.
