Design and Experiment of Squirrel Cage Pressure Roller Type Suppression Device for Potato Full-scale Cultivator
摘要
Abstract
Aiming to address the issues of excessive soil disturbance,thickened plow pan,and intensified wind/water erosion associated with conventional land preparation methods.It focused on the optimized design and performance analysis of a compaction device for a wide-width comprehensive tillage machine used in potato cultivation,systematically investigating soil fragmentation and leveling techniques during pre-planting land preparation.Combining theoretical analysis with numerical simulation,a contact mechanics model between the roller bars and soil was established to analyze the influence of device weight and soil interaction mechanisms on operational effectiveness.This approach identified optimal ranges for key structural and operational parameters of the compaction roller.An EDEM-based discrete element model of the soil-compaction device interaction was developed.A three-factor,five-level quadratic orthogonal rotation regression test was conducted,considering operational speed,roller bar diameter,and bar rotation angle as test factors,with soil fragmentation rate and surface leveling as evaluation metrics.Simulation results demonstrated soil fragmentation rate of 86.32％and leveling precision of 21.55 mm.Field validation tests confirmed significant performance improvements:the optimized device achieved soil fragmentation rate of 85.31％(2.09 percentage points higher than that of conventional equipment)and surface leveling precision of 25.2 mm(6.9 mm improvement over that of the ZY-180 roller).Experimental data verified that the designed cage-type roller not only integrated well with the host machine but also met agronomic requirements for potato field preparation.关键词
