植保机械在线混合系统质量评价体系与研究
|
摘要
植保机械的混合均匀性直接影响施药质量,而施药质量对农药的使用效果有着密切的联系。该文提出了混合度的理论与测定方法,避免了用轨迹研究方法研究混合均匀性的烦杂的计算,比以往用均匀性来评定混合效果更科学合理,同时,对植保机械在线混合用的混合器与射流混合系统等进行了研究评估。
The mixing uniformity of the plant protection machinery has usually influenced the application quality of pesticides,and the application quality of pesticides has a close relation with the using effect of the pesticides. This paper presented the mixing degree's theory and its measuring method. It avoided the multifarious calculations of utilizing the trajectory method to research the mixing uniformity,and it is more scientific and reasonable than previous using the uniformity to evaluate the mixing effect. Meanwhile,the article also researched and evaluated the mixer and the jet mixing system of the plant protection machinery which were for on-line using.
