摘要 以分置式一机三用型耕播机为研究对象,设计三点悬挂连接机构。从分置式耕播机连接机构的设计原则出发,分析了单机连接机构的有效间距。从机组纵向稳定性储备利用系数和爬坡稳定性系数分析了耕整联合作业机组的抗倾翻能力,确定连接机构有效尺寸的最大值为41 cm;通过分析旋耕刀的运动状态、土块的被抛位置和初速度,并对其进行计算和试验,确定连接机构有效尺寸的最小值为19 cm。 以分置式一机三用型耕播机为研究对象,设计三点悬挂连接机构。从分置式耕播机连接机构的设计原则出发,分析了单机连接机构的有效间距。从机组纵向稳定性储备利用系数和爬坡稳定性系数分析了耕整联合作业机组的抗倾翻能力,确定连接机构有效尺寸的最大值为41 cm;通过分析旋耕刀的运动状态、土块的被抛位置和初速度,并对其进行计算和试验,确定连接机构有效尺寸的最小值为19 cm。
