| Abstract: | The work component of the deep-digger which is hitched to Model GN-5 Walking Tractor is a kind of excavating tillage mechanism. It can perform the tillage of the soil block in original line, so it is suitable to cultivate the forest nursery, orchard and so on. This paper related how to design the mechanism with the objective and concise geometrical method and introduced in detail the process of designing the four-bar linkage by means of the rotary center curve and the relative motion principle according to the demands on the work path of the hoe-tip. Also, the velocity, acceleration, forces acted on the mechanism and its equilibrium were analysed. Though examination of path recurrence and the field tests, it was proved that the tillage depth, the evenness of ditch and the working stability of the deep-digger met the demands of design and agrotechnique |
