| Abstract: |
| Sovling the problem of lower power is the key to the perfection of a complete set of combine with small power tractor. In order to find a way to lower power consumption of threshing and separating parts, a special testing table was designed for the experiment. A two-year in-lab test was conducted on the optimum working parameters and structure of threshing drum using orthogonal test'design. The results showed that when the feeding capacity was 0.75 kg/s, total power comsumption of threshing and cleaning could be controlled below 4.4 kw. Also, this paper briefs on the field testing conditions of power1 consumption and performances of Feilong-0.75 grain combine developed in accordance with the testing results. |
