笔者以山东德州华北农机厂生产的4J-150型秸秆切碎还田机配套铁牛-60型拖拉机为例,简单地谈一谈玉米秸秆切碎还田作业应注意的几个问题。 (1)合理使用挡位。由于独立式动力输出轴的转速仅与发动机的油门大小有关,而与变速箱的挡位高低无关,所以使用挡位过高,会使秸秆切碎效果差。一般来说,应根据土壤的干湿程度、玉米的种植密度,选用较低的挡位
The author takes the 4J-150 straw chopping and returning machine produced by North China Agricultural Machinery Factory in Dezhou, Shandong Province as an example to support the tractor of Taurus -60, and briefly talks about several problems that should be noticed when the corn straw is shredded and returned to the field. (1) the rational use of gear. Since the speed of the independent power output shaft is only related to the size of the throttle of the engine, and has nothing to do with the gear of the transmission, the use of the gear is too high and the straw chopping effect is poor. In general, should be based on the degree of dry soil moisture, planting density of corn, choose a lower gear
