Profiling Mechanism of 2BY-6 Type Breeding Test Plot Seeder

Profiling mechanism is an important part of plot seeder.It plays an important role on improving the stability of sowing depth and consistency.Types and working principle of profiling mechanism were studied.Structure characteristics，working principle and size parameters etc of the depth limit wheel of profiling mechanism were analyzed.A suitable limiting wheel profiling mechanism of plot seeder was designed in order to reduce error of breeding test and improve accuracy of breeding test data.
