小型轴流滚筒结构及工作参数优化试验

Testing on Structure and Working Parameters of the Small-sized Axial-Flow Drum

解决动力偏低是小动力拖拉机配套联收机的关键问题,为寻求降低脱粒、分离部件功耗的途径,本研究设计了专用试验台架,用正交试验法,就脱粒滚筒的结构、工作参数优化等问题,进行了两年的室内试验。结果表明,当喂入量在0.75kg/s时,脱粒、清选全部功耗可控制在4.4kW以下。文中对根据试验结果研制的飞龙-0.75联收机的功耗、性能、田间实测情况也作了简要介绍。

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.
