摘要
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、开沟装置。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%,保留秸秆覆盖量提高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。
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.
