Abstract
The acting forces between soil and potatoes in the process of harvesting by vibration loads are complicated. In order to study the effect of the exciting forces for the dynamic characteristics of potato conveying and vibration separation system, taking potatoes with soil on them and equivalent viscoelastic material as a whole, a mechanic model was establish for the potato conveying and separation system considering the sectional material forces between the potatoes, the soil and the shaker chain in the conveying, separating, crushing and screening process, and then analysis of the model was conducted by asymptotic method numerical integration. The results show that the dynamic characteristic of the conveying and separation system is more complicated under specific conditions, and the system motion is chaotic. The test further shows that the rational use of vibration can improve the separation rate of potato and soil, and improve the harvest quality.
