An anti-blocking mechanism combined driven divider with passive residue separating device was designed, using simulation method and fields experiment to determine key parameters of the components. Based on the results of the simulations, the optimum parameters of driven divider were 1.24 speed ratio, 5 bars and 150mm diameter. The convex residue separating device with 750mm average radius had the strongest diffluent ability. Field experiments of seeding performance of 2BYJMFQC-4 maize precision no-till seeder, on which the anti-blocking mechanism combined driven divider with passive residue separating device was fixed, was conducted, and the results showed that the passing ability, the sowing quality, the sowing depth rate and the fertilization depth rate satisfied the requirements of the national standard. Above all, the anti-blocking mechanism combined driven divider with passive residue separating device was effective in solving straw blocking and ensuring the passing performance of the no-till maize planter.
