高地隙窄形橡胶履带式水旱兼用行走系统设计

Design of High-ground-clearance Narrow-rubber-pedrail-type Running System for Paddy Field and Upland

研制了一种高地隙水旱兼用行走系统,特别适用于水稻田植保作业,分析了其工作原理,并对履带、驱动轮或导向轮、支撑轴承座等关键部件进行了设计计算,通过性能试验表明:该行走系统工作性能稳定,地隙达1 m,防陷深,压苗少。

A high-ground-clearance narrow -rubber-pedrail-type running system for paddy field and dry upland was de-veloped, which was especially suitable for plant protection work of paddy field .The working principle of this running system was an-alyzed.The pedrail, driving wheel or guiding wheel , supporting bearing and other key parts were designed and calculated .The per-formance tests showed that the system had stable working property with the ground clearance of 1 m, and prevented the wheels from sinking into the deep earth, so that few seedlings were squashed .
