摘要
鸭嘴式成穴器的活动嘴开启机构是影响成穴器性能的主要因素之一.为了克服传统启闭机构容易失灵的缺点,本试验中研制了一种凸轮-平面四杆式开启机构,并确定了该凸轮-平面四杆式开启机构的关键参数.
The opening structure is one of the main factors that affects the performance of soil opener.In order to overcome the shortcomings of the traditional opening mechanism,a kind of cam and planar four-bar linkage with stable and reliable performance has been designed,of which the key parameters as the theoretical basis for reasonable design of the structure were provided in this paper.
