Response Surface Analysis of Pickup Losses in Two-stage Harvesting for Rapeseed

Abstract:

In order to reduce the loss rate in picking up, parameters of pickup device with response surface analysis methods was studied. The results showed that main factors of impacting pickup loss rate were the moving speed, belt speed and conveyor inclination. The three factors gradation of importance was the moving speed, belt speed and conveyor inclination. Optimal group of parameters was the moving speed of 0.80m/s, the belt speed of 0.78m/s，the conveyor inclination of 11.19°, the optimal loss rate of 2.91%. Considering of parameters adjusting in actual conditions, recommended parameters were that the moving speed of 0.71m/s, the belt speed of 0.80m/s, the conveyor inclination of 12°.
