2BM―5型草原药用免耕播种机的研制

Development of 2BM-5 No-till Planter for Planting Medicine in the Grasslands

针对甘肃省甘南草原上大面积种植中草药项目缺乏配套农机具的问题,研制了2BM―5型圆盘式草原药用免耕播种机。提出了在潮湿和多石块的草原上采用双圆盘开沟器、用分离式刚性镇压器的播种机型;分析和确定了开沟器、镇压器等关键部件的结构参数。田间试验结果:采用2BM―5型免耕播种机能够保证单位面积的基本苗数,种子深度合格率87.5%,出苗率提高6.85%,能满足作物生长需求。

Develop the 2BM-5 disk no-till planter in the condition of planting Chinese traditional medicine largely in the south grasslands of Gansu Province. Advance the double disks digger with the rigid-separate scotch wheel which can work in the grasslands in the instant of wet and blocks land. Analyze and confirm the structure parameter of the key parts. Test in the fields and the consults： ensure the basic number of the seedling in unit area, certified rate of the deepness is 87.5%, seedling rate increase by 6.85%, and satisfy the demand of the up growth.
