玉米脱粒机设计
摘 要:本次设计的玉米脱粒机其工作原理为电机经皮带轮传动, 玉米穗通过料斗进入滚筒,在高速回转滚筒的冲击和玉米穗、滚筒、凹板的相互作用下被脱粒。脱下的子粒大部分通过栅板漏下。穗轴则沿滚筒轴向往后移动,通过筛子表面流出机外。夹带在穗轴中的部分子粒也经过筛孔漏下。风扇的作用是将夹在子粒中的轻杂带走。与同类产品比,结构紧凑,性能优良,操作轻便,安全可靠,且不占场地,搬运存放方便。破碎率很低,可提高种子发芽率。能大大减轻农民劳动强度,有利于抢赶农时季节,促进农民致富,推动农业的发展。适宜在广大农村推广应用。

The Design of the Corn Thresher
Abstract: This design of the corn sheller is principle of work is that electrical machinery is driver mealies are put into the drum through the hopper, in the impact of the which is rotating in high speed the impact and the mealie, the drum, under the notch-board mutual function is extracted seeds. Majority of seeds are taken off through notch-board hole. Then the ear axis axial will move along the drum flow out the outside of the screen surface of the aircraft. The partial of seeds smuggling in the ear axis are discharged through the mess mild of the clamps light which are mixed in the seed. Compared to the similar product, the strudures in compact the performance is fine, the operation is facile, safe reliable, also does not occupy the location, transporting depositing is percentage of damage is very low, may enhance the seed-germination percentage.Can reduces the farmer labor intensity greatly, is advantageous in snatches catches up with the farmer season season, promotes the farmer to become rich, impels agricultural the development.Being suitable in general countryside promotion application.
