Abstract
In this paper, a novel volute linear directing plate and inverted “Y” structure stubble board are first designed to address the problem of straw agglomeration. Then a flexible and breakable discrete element model of tillering straw is proposed, and a discrete element coupling model of flexible tillering straw-crushing and strip-laying device is also constructed. The results show that the model can predict the operation performance of the crushing and strip-laying more accurately. Finally, the effect of spindle speed, directing plate radius and stubble board angle are investigated in-depth. In addition, the structure optimization of the directing plate and stubble board is conducted by response surface method, and the corresponding field test is also conducted. It is demonstrated that the coefficient of seed zone cleaning increased by 4.6 %, and the coefficient of straw ridge disturbance decreased by 34.6 %, meanwhile, the device performance is greatly improved after optimization.
