Abstract: In view of the large amount of wheat straw coverage and the difficulty with the high-speed working process used in traditional rotary tillage row cleaner. A row cleaner with staggered disc teeth for no-till planting was designed. It was determined that installation with a forward inclination α , horizontal declination β, and forward speed v 0 of the machine were the main factors affecting the straw cleaning rate Y 1 and working resistance Y 2 , and the range of values for structural parameters and motion parameters of the row cleaner were determined. Taking α , β, and v 0 as the factors and Y 1 and Y 2 as the response indexes, using EDEM 2018 software to simulate the straw cleaning process under different parameters and determine the influence of each parameter on the straw cleaning performance. After performing a soil bin test, the results showed that there was no straw entanglement and blockage, and the passability was better than that of the traditional flat disc separated row cleaner. When α was 70°, β was 30°, v 0 was 8 km/h, and the embedded depth h of the soil (straw) was 55 mm, the average straw cleaning rate was the highest, which was 90.59%. This study provides a new idea for the design of high-speed corn no-till planters in the Huang-Huai-Hai area of China.
