Evaluation of the Performance of a Combined Tillage Implement with Plough and Rotary Tiller by Experiment and DEM Simulation

In order to improve the performance of tillage tool for straw incorporation in silty clay loam, a combined implement with plough and rotary tiller was designed. Its on power consumption investigated, types (CTSR CTDR) were compared traditional including sole type (SP DP), (RT), two-pass (SP+RT DP+RT) rice field experiment. The effect forward speed RT CTSR studied by DEM simulation. ratio coverage CTDR increased nearly 20% RT, stability coefficient depth CV surface evenness after also improved total less than that measurement. simulation indicated increase speed, reduction can be obtained at relatively high speed. had an advantage some operational conditions.
