摘 要：
No-tillage precision seeder is one of the most widely used agricultural seeding machines in the conservation tillage technology application. For 2 BMF-3 type no-tillage precision seeder in stubble field,the best stem design technical parameters were obtained through analyzing from the whole machine structure and the working principle,to the designation and research on the key anti-blocking device,and improving a series of parameters such as the blade shape of the anti-blocking device,the depth of the soil contraction and the running speeding in the operation. This can ensure that the crop seeds achieve high soil penetration rate and soil depth rate in field,and the optimal seeding efficiency in the seeding sowing process of precision seeder,the design was applied to the actual production test,and the result is about90%. The design and production test of the key anti-blocking parts about this type no-tillage precision seeder can provide some reference value for the development and improvement of other mechanical automation production equipment in wheat stubble field and the further development and application on the related technology fields.
