旱地全膜双垄沟播直插式玉米播种装置的仿真优化
Optimization of simulation of direct-insert corn planting furrow seeder for whole plastic-film mulching on double ridges in dry land
摘要
Abstract
To meet the demand of seeding on film,a new type of direct-eeding device,with a parallel four-bar mechanism driven by crank slider mechanism,was designed.Due to its simple structure and high precision,the device could achieve "zero speed" sowing of hole-forming device.Aiming at the optimization of the speed difference v of the hole forming device with respect to the x direction of the frame,and the horizontal displacement difference s between buried and the pipe line,the structure of the device was optimized in Solidworks Motion.It was found that when using 0.5 m· s-1 as the forward speed,the length of the crank Ⅱ and the length of connecting rod were 69 mm and 167 mm respectively,and the speed of crank was 100 r· min-1.Thus the optimal direct seeding performance could be achieved.关键词
