Performance Comparison of Two Types Dibble Planting Devices

Structure features，moving track，dynamic characteristics，accuracy of catching seedlings and the highest working efficiency of two types dibble planting devices were analyzed and compared.Single dibble planting device could obtain ideal trajectories and higher accuracy of catching seedlings through reasonable design on parameters of crank connecting rod.It could reduce soil interference during planting and its weight was small.But it was not suitable for high speed operation because of large movement impact during working.Trajectories of dibble for multiple dibbles planting device was trochoid motion following drive device.This dibble planting device could work in high frequency and fit different spacing in large scope.Its movement impact was small.But the size of its dibbles is smaller and its weight was large.
