摘　　要：利用平面机构的力分析方法,建立了运动副中摩擦力的数学模型,并对播放机构中种绳与转管之间的受力状况进行了分析研究,建立了参数计算模型;同时,对播放机构的结构进行了分析研究,利用研究结果对播放机构进行整体设计,确定结构方案。通过田间试验,可知该播放机构具有较好的播放效果。该研究为水稻种绳直播播放机进一步的开发研制提供了参考依据。Mathematical model of friction between the movement objects was established by the analytic force method of the plan mechanism. The interplay between seed rope and running rube were analyzed. Meanwhile, these parameters of the calculate model were set up. By using the theoretical study results, the seeding structure for the machine of rice sowing with rope was designed. It bring about some good effects in the cultivation and the result offered a reference for the further development of the machine of rice sowing with seed rope.
