| Abstract: | 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. |
