Design and experimental study of precision variable fertilization device for multi fertilizer mixed application
摘要
Abstract
In response to the problems of single fertilizer types,inflexible fertilizer ratio adjustment,and poor fertilizer u-niformity in traditional fertilization devices,this paper designs a multi fertilizer mixed application structure based on me-chanical layered fertilizer supply and independent fertilizer discharge structures,realizing the separate and quantitative transportation,real-time ratio adjustment,and mixed application of different fertilizers.The type of fertilizer discharge device,spiral conveying parameters,and transmission system are designed,and a relationship model between fertilizer discharge amount,speed,and opening is established to achieve continuous adjustable and variable control of fertilizer a-mount.The prototype test results show that the device runs smoothly,the fertilizer discharge process is continuous and reliable,and it has good adaptability to different fertilizers.The multi fertilizer mixing ratio is stable,which can meet the requirements of precision fertilization.关键词
