| Abstract: | In order to solve the problems of wheat no-till seeders in annual double cropping area of North China Plain such as large amount of straw-covering, stubble-bulky, residue-blocking, and bad passing capacity and planting quality, the new anti-blocking device using floated support was designed. This paper elaborated the working principle. Major working parts of the anti-blocking device were designed, and the structure parameters were determined. The field experiment showed that the no-till planter with floated support anti-blocking device had good passing capacity. Compare with strip-rotary anti-blocking device, floated support anti-blocking device reduced soil disturbance and oil consumption by 25% and 7.04% respectively. |
