EFFECT OF TINE FURROW OPENER ON SOIL MOVEMENT LAWS USING THE DISCRETE ELEMENT METHOD AND SOIL BIN STUDY

The mechanism of furrow opener-soil interaction plays an important role in analyzing the process no-till planting opener. In order to study disturbance effect opener on loam soil, firstly, three-dimensional model was established by using SolidWorks. Secondly, 3D discrete element EDEM software. Combined with indoor soil bin test bench and high-speed camera technology, micro-disturbance macro-disturbance behavior at different positions, speeds operating depths were compared analyzed. results showed that, range decreased increase distance between soil. At locations, from large small surface layer, shallow layer middle layer. Under conditions three layouts openers, through comparison trench simulation test, it determined that openers a staggered layout would be beneficial reduce degree disturbance. trenching process, movement velocity opener, distribution curves same-speed particles basically consistent average velocities directions However, there differences maximum directions. By comparing data obtained found parameters consistent, could simulate more accurately. relative errors cross-sectional area front rear 2.48 % 5.2 %, respectively. dynamic rate 0.25 5.12
