为解决南方冬油菜产区田间前茬作物留茬高及杂草丛生对油菜苗期生长的影响,有必要在播种同时对土壤进行浅耕除草,灭茬.2BYD-6型油菜浅耕直播施肥联合播种机,将浅耕工作部件和旋转开沟部件安装在同一根刀轴上,采用地轮传动提供排种,排肥系统动力.设计了用于改变排种,排肥轴转速从而达到调节和控制播种量和排肥量的变速机构.可以实现浅耕,灭茬,开排水沟,播种和施肥等联合作业.试验表明:该播种机工作安全可靠,灭茬率大于95%,漏耕率小于5%.该机能够满足南方冬油菜的直播技术及农艺措施要求

To decrease the influence of high stubble and heavy weed on the growth of rapes at the seedling stage in southern winter rape fields, it is necessary to eliminate weed and stubble by shallow tillage before sowing. 2BYD-6 shallow tilling and fertilizing seeder for rapes was designed, and the shallow tilling working parts and rotary tillage ditching parts were fixed on the same cutter shaft, and driven wheel was adopted to provide power for seeding and fertilizing. Furthermore, for controlling the seeding and fertilizing quantity, speed changing mechanism which was use for adjusting the rotate s...
