Abstract

In the northeast ridge area，the stubble treatment and subsoiling operation before planting can improve the quality of seeding and promote the growth of crop. In the process of operation，available machines for subsoiling and stubble-breaking exist some problems，including the large amount of soil disturbance，the not ideal effect of stubble cleaning and stubble-breaking roller is easy to tangle with grass etc. At the same time，in order to adapt to the technology mode of conservation tillage in the northeast cold，and meet the agronomic requirements of ridge deep loosening stubble, a type of subsoiling and stubble-breaking machine was designed, of which the structure of stubble-breaking parts，subsoiling component and ridge forming parts were designed. Also，the field experiments were carried out to study the structure and operating parameters affected the machine. The influence factors of field experiment included the speed of working machine，the depth of stubble-breaking and the sliding cutting angle of sidelong edge for stubble-breaking blade. Evaluation indices included the rate of stubble-breaking and the depth stability coefficient of stubble breaking. The results showed that when the speed of working was 2.8km/h，the depth of stubble-breaking was 84.9mm，the sliding cutting angle of sidelong edge for stubble-breaking blade was 6.5°，the rate of stubble-breaking was 93.26%，the depth stability coefficient of stubble breaking was 95.25%. The stubble-breaking effect of stubble-breaking machine was ideal，which met the quality requirements in working.


Keywords: strip subsoiling and stubble-breaking machine, stubble breaking rate, depth of stubble breaking stability coefficient, parameter optimization,field test
