| Abstract: |
| ln order to obtain the working parameters of longitudinal axial conical cylinder threshing separation unit for plot breeding, an experiment was conducted in the light of plot seed harvest mechanism, by changing 4 main opera-tional parameters(feed quantity, rotate speed of cylinder, threshing clearanee, rotate speed of gettering fan)which influ-enced the unit performance indexes, with the residued rate of shell intemal, the total loss rate, the trash content of cleaning rate and the broken rate as evaluating indicators. Through the orthogonal experiments, application overall rating method to obtain the optimal combination working parameters(feed quantity:0.3 kg/s, rotate speed of cylinder:1 600 r/min, threshing clearance:8mm, rotate speed of gettering fan:1 100r/min)of the unit. Measured with the optimal combination of operational parameters, the experimental results showed that, the total loss rate was 0.45%, the trash content of cleaning rate was 16.16%, the residued rate of shell internal was 0.04%, and the broken rate was 0.46%, which could meet the demand of plot seed harvest. |
