Abstract

A rubbing thresher was developed and evaluated on threshing some seed crops as flax and sunflower. The performance of the developed machine was tested in two independent experiments according to the kind of crop by studying some engineering factors that affecting threshing operation such as threshing drum speed, threshing belt speed, and concave clearance. The flax experiment was performed by testing the drum speed at 4.2, 5.5, 6.4, and 7.3 m/s, threshing belt speed at 0.42, 0.67, 0.96, and 1.25 m/s, and concave clearance at 1.5, 2.5, and 4.0 cm. In addition, the sunflower experiment was performed at the same levels of drum speed and belt speed addition to other three levels of concave clearance of 2.5, 4.0, and 5.5 cm. The results showed that, the drum speed of 7.3 m/s, belt speed of 0.42 m/s, and concave clearance of 1.5 cm were the optimum conditions for threshing flax crop by the developed thresher. In addition, the optimum conditions for threshing sunflower by the rubbing thresher were 7.3 m/s, 0.42 m/s, and 2.5 cm of drum speed, belt speed, and concave clearance respectively.
