Design and kinematic simulation of clip seedling mechanism for an onion seedling transplanter
摘要
Abstract
At present,transplantation of onion is done artificially in china,which causes labor-intensive,low productivity, poor quality planting and high production cost. In order to improve the efficiency of onion transplantation,a clip seedling mechanism was designed for transplanter of onion seedling. First, design calculations and theoretical analysis of clip seedling mechanism were carried on. And a 3-D parametric model and kinematic simulation of clip seedling mechanism were built up with Pro/E. Curve fitting and data analysis were built up with MATLAB. Then structure and motion parameters of the mechanism were optimized. The results show that the three main factors, influencing the effect of transplantation, are the range of motion of clip seedling mechanism, the opening-closing scope of opening-closing fixture and speed ratio of the lifting cylinder to telescopic cylinder. The corresponding parameters got by optimization are 0 - 53.3 mm,0- 27.8 mm and 1.0, respectively. Feasibility of program for the clip seedling mechanism is verified. This article provides a theoretical support for the design and testing of transplanter of onion seedling.关键词
