介绍一种新型的２ＢＤ－８自走型分流式小型水稻直播机的主要结构特点，并对其进行了室内、田间及生产对比试验。试验结果表明，电磁振动式播种机按播种量分档加接分流盘，能有效地提高直播机的各项工作性能指标。该机工作性能好、工效高，用其进行水稻直播机械化生产，可达到省工、省时、节能、高产的目的。 The main structural features of a new type 2BD-8 self-propelled split-flow mini-rice direct seeding machine are introduced. The comparative experiments of indoor, field and production are carried out. The test results show that the electromagnetic vibratory seeder according to the amount of seeding affixed to the shunt plate, which can effectively improve the direct seeding machine performance indicators. The aircraft working performance, high efficiency, with its direct broadcast mechanized rice production, can save labor, save time, energy saving, high yield purposes.
