斜置驱动圆盘免耕播种机设计与试验

针对一年两熟地区免耕播种小麦时存在的问题．提出利用斜置驱动缺口圆盘作为灭茬、开沟装世。对结构的关键参数进行了分析和确定。田间对比试验结果表明．单位面积油耗比条带旋耕免耕播种机有所下降，地表动土量减少20％，保留秸秆榭盖量提高20％，同时斜置驱动圆盘免耕播种机通过性能良好．入土能力强．可创造良好的种床条件。

Design and Experiment of No-till Planter with Oblique Driven Disc

An oblique driven disc cutting mechanism to treat corn stalk and rootstalk is developed for no-till drill in the area of two crops a year and a new scheme of no till drill equipped with it has been developed. The key parameters of the mechanism were optimized. The experimental results of the sample machine in the no-till field, compared with the band-rotary no till drill, show that the fuel consumption is lowered and the disturbance of soil surface decreases about 20%. It has a good ability to cut corn stalk and rootstalk and opens seed furrows with minimum soil tillage and small vertical force. A good seedbed made by it is beneficial to seed germination and seedling growing.
