果园定向施肥机施肥系统结构设计

Structure Design on Fertilization System of Directional Fertilization Machine for Orchard

为解决江西省丘陵山区大面积果园施肥作业缺乏合适作业机械的问题,分析了国内果园施肥的现状,针对江西省复杂地形设计了果园定向施肥机的施肥装置。基于现代果园的施肥农艺标准,提出了施肥系统结构方案,设计成不完全齿轮传动以适应定向施肥要求,并进行了施肥部分的计算。设计了关键结构:适合不同肥量的搅龙排肥装置和适应南方地形的仿形装置。该施肥机能够在树根附近定向施肥,节省肥料,提高肥料利用效率,施肥量大而且可调。

In order to solve the problem on the lack of proper fertilization machine in large area of orchard in Jiangxi province,current situation of domestic orchard fertilization was analyzed. Fertilizer apparatus of directional fertilization machine for orchard was designed based on the complex terrain in Jiangxi province. According to fertilizer agronomy standard of modern orchard,structure scheme of fertilization system was put forward. Incomplete gear transmission mode was designed in order to adapt to the directional fertilization requirements. And calculation of fertilization part was made. Key structures such as mixing fertilizer device suitable for different quantity of fertilizer and terrain profile device to the south were designed. This machine could fertilize near by the boot of plant,could save fertilizer,promote fertilizer use efficiency,and adjust the fertilizer in wide-range that adapt to the different fertilizer rate.
