水培凉粉草收割装置的设计与试验OA

Hydroponic cultivation of Mesona chinensis can improve its growth efficiency.However,currently,the harves-ting of hydroponic Mesona chinensis mainly relies on manual labor.Therefore,a harvesting device is needed to reduce la-bor intensity,improve efficiency,and ensure the consistency of harvesting quality.Fot this,a new harvesting method that preserves the roots of Mesona chinensis was proposed.According to the functional requirements that the harvesting device needs to achieve,the design of key components of the harvesting device was carried out respectively from aspects such as the planting plate moving mechanism,cutting mechanism,conveying mechanism,and transmission system.Through sin-gle-factor experiments,the influence of the blade edge angle and cutting angle on the cutting force of Mesona chinensis stems was analyzed.The research found that reducing the blade edge angle and increasing the cutting angle can effectively reduce the maximum cutting force,thus reducing the power consumption during the cutting process.15°and 30°were the optimal edge angle and cutting angle respectively.Using orthogonal experiments,the influence of feeding speed,planting plate inclination angle,and cutting speed on the cutting success rate was studied.The results of the orthogonal experi-ments showed that the order of significance of the experimental factors was feeding speed,planting plate inclination angle,and cutting speed.The optimal combination parameters were feeding speed of 0.5 m/s,planting plate inclination angle of 15°,and cutting speed of 1.1 m/s.The average cutting success rate reached 90%,which can ensure the harvesting qual-ity while successfully completing the harvesting work.
