2BMFS-6/12型免耕覆盖施肥播种机(以下简称免耕播种机)适应性强、通过性好,但动力消耗较大,作业效率也不高。究其原因,与旋转刀具的形式及其在刀轴上的排列有很大的关系。原来,免耕播种机是旋耕部分和播种部分的组合体,免耕播种机的旋耕刀数比同型号的旋耕机少了10把,是旋耕刀的排列方法(见图1)不合理而形成了性能上的缺欠,需要改进。1.思路(1)T型刀主要用于挑茬,直刀主要用于破茬。使用中发现,机 2BMFS-6/12 No-tillage and Covering Fertilizer Seeder (hereinafter referred to as no-tillage seeder) adaptability, good sex, but the power consumption is large, the operating efficiency is not high. The reason, with the form of rotary tools and their arrangement in the arbor has a great relationship. It turned out that no-tillage planter is part of the combination of rotary and planting parts, no-tillage planter rotary cutter than the same type of rotary tillage machine less 10, rotary tine arrangement method (see Figure 1) Irrational and formed a performance deficit, need to be improved. 1 ideas (1) T-knife is mainly used for stubble, straight knife is mainly used for stubble.
