摘要

小型自走施肥机是一种可以在农田里中将化肥与液体肥料施放和喷洒到指定位置的\t/_blank机械。拥有提高升施肥和喷洒液体肥料过程速度作用，同时还可以保证\t/_blank合理的化肥的用量。它不仅能够提高人们劳动工作的效率，同时也能够减轻人们的劳动负担，让大家生活变得更好，实现劳动机器化、自动化。

此设计对小型自走施肥机整体结构的关键零部件进行了强度分析和校核。小型自走施肥机的整体结构主要由以下部件组成：车架、车轮、支架、传动轴1、凸轮、摆臂、喷洒头、液体肥料箱、锥齿轮、链轮、减速器、肥料箱、覆土铲、开沟盘、开沟刀和犁等。这些零部件共同构成了小型自走施肥机的完整结构。

在设计过程中，我采用了SolidWorks数字化建模软件，实现了小型自走施肥机零件图和总装配体的三维数字化建模。同时，我还对关键零部件进行了相关的强度分析，以确保其满足设计和使用要求。
