摘　　要：针对双轴击切式破碎秸秆和根茬所存在的问题 ,本文提出单轴压切原理和非等长刀切碎模型 ,并对秸秆切碎灭茬机的关键参数进行了优化设计。该机田间试验表明切碎率达 91.4% ,根茬破碎率达 86 .5 %。该机的应用必将促进一年两熟平作旱区保护性耕作技术的发展。For the problem of breaking stalk with hit shear type and stubble with double shafts, the principle of press chop type with single shafe and the models of chopping with knife of different radius are put forward. The key parameters of chopper are optimized. The outcome of field test shows that the rate of chopping is up to 91.4% as well as breaking 86.5% stubble. The application of this chopper is surely promoting technology of reservative tillage in dryland.
