Multi-purpose seeding mechanism test platform design
Abstract:
The article opening introduced the advanced seeding mechanism test platform existing fine broadcasts the seeding mechanism regarding the understanding and grasping the technical performance, studies and develops the new generation of high performance seeder the importance, this design introduced one kind of new seeding mechanism test platform mechanism and the electrical part parameter design calculation method, as well as the electrical equipment selects the basis: And has given the overall structure disposition chart.The seeding mechanism test platform structure may in the experiment simulate each kind of precision seeding mechanism high speed work condition, and achieved the precision measuring plants the goal which the seed is apart from.This design introduced systematically this seeding mechanism test platform design process and the method, and have inserted some diagrams in the computation process, is more advantageous to the understanding.Has the rigorous manner in design each process, guarantees various data the accuracy.
Key words:Agricultural engineering; Seeding mechanism test platform; Design
