Design and Experiment of Row Cleaner with Staggered Disc Teeth for No-Till Planter

In view of the large amount wheat straw coverage and difficulty with high-speed working process used in traditional rotary tillage row cleaner. A cleaner staggered disc teeth for no-till planting was designed. It determined that installation a forward inclination α, horizontal declination β, speed v0 machine were main factors affecting cleaning rate Y1 resistance Y2, range values structural parameters motion determined. Taking as Y2 response indexes, using EDEM 2018 software to simulate under different determine influence each parameter on performance. After performing soil bin test, results showed there no entanglement blockage, passability better than flat separated When α 70°, β 30°, 8 km/h, embedded depth h (straw) 55 mm, average highest, which 90.59%. This study provides new idea design corn planters Huang-Huai-Hai area China.
