Study on the Circle and Ellipse Pitch Curve of Non- circular Gear Train Transplanting Mechanism

Abstract

In order to improve the work quality of rice transplanter,a planetary gear transplanting mechanism which gear pitch curve composed of circle and ellipse arc is designed. According to the mechanism kinematics model,the assistant analysis software is written. By the software analysis,the transplanting mechanism seedling claw trajectory is obtained and the trajectory is almond shaped,it is to the benefit for seedlings orthostatic. The mechanism meet the planting requirement.
