| 中文摘要: |
| 针对膜上播种需求，设计了一种新型曲柄滑块机构驱动平行四杆机构直插式播种装置，该装置结构简单，能够实现播种时成穴器“零速”播种，不易挑膜、撕膜。以成穴器相对于机架x方向的速度差v、排种管入出土后水平位移差s为优化目标，在Solidworks Motion中进行了该装置结构优化仿真。得到结果为：当以0.5 m·s-1为前进速度时，曲柄Ⅱ长度69 mm、连杆长度167 mm、曲柄机构转速100 r·min-1的播种装置能得到较好的直插播种性能。 |

| 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. |
