云南省大理州农机研究所、弥渡县农机管理站和农机修造厂在综合现有多种脱粒机基础上,改进设计成5TX-500型稻麦脱粒机。该机由机架、罩壳、滚筒、搓板、凹板、风选简、轴流风扇、电机等部件组成。由于增设了搓板机构,在小麦脱粒时,使被弓齿打断的麦穗头在搓板的作用下得到再次脱粒,从而大大提高了脱净率。此外该机还巧妙地设计了轴流风扇,利用气流进行分质清选,达到籽粒与杂物分离,既能脱粒小麦,也可脱水稻。
Yunnan Dali Agricultural Machinery Research Institute, Midu County Agricultural Machinery Management Station and agricultural machinery repair plant in the existing variety of thresher based on the improved design into a 5TX-500-type wheat thresher. The machine consists of rack, shell, drum, washboard, concave plate, wind election Jane, axial fans, motors and other components. Due to the addition of a washboard mechanism, when the wheat is threshed, the wheat head interrupted by the bow teeth is thresholded again under the action of the washboard, thereby greatly improving the removal rate. In addition, the aircraft also ingeniously designed axial fans, the use of air quality separation, to grain and debris separation, both threshing wheat, but also dehydrated rice.
