When wide-width sowing wheat after rice stubble (WRS) in a rice-wheat rotation area, there is problem of poor uniform seed distribution. To solve the problem, this study designed distribution plate (SDP) structure and optimized its critical parameters. Firstly, combined with operating principles seeder agricultural standards for WRS, main structural parameters affecting movement were determined by theoretical analysis grain dynamics SDP structure. Secondly, operational performance six...
The uneven sowing of wheat on ground covered with rice straw in the rice–wheat rotation area middle and lower reaches Yangtze River has become a serious problem. Therefore, test bed for throwing soil after wide seed belt was designed, which could complete functions crushing, lateral concentration uniform at one time. discrete element simulation model established rotary blade shaft speed, guide plate angle retaining as variables. Taking variation coefficient depth uniformity evaluation...
In recent years, there have been many studies on the calibration of soil simulation parameters; however, are few parameters for wheat grown after rice that calibrated in lower reaches Yangtze River, and data from such calibrations remain inaccurate. Therefore, using Jiangsu as our research object, a parameter was carried out based EEPA (Edinburgh elastoplastic adhesion) model discrete element software EDEM (2020, DEM-Solutions, Edinburgh, UK). The depression depth measured via uniaxial...
The soil during the sowing period of wheat after rice stubble cannot be accurately described by existing models and parameters with DEM because its high moisture content strong viscosity. purpose this study is to conduct an overall simulation high-viscosity paddy analyze accuracy model. Based on results unconfined compression test shear test, range bond preliminarily determined a test. Through P-BD RSM significant influence are normal stiffness per unit area (SN), (SS), critical stress (CS),...
Waste plastic film often contains an abundance of impurities, such as crop stems and soil. To address this issue, a toothed-plate single-roller crushing device for waste was developed. By analyzing the movement force pattern film, feeding speed, number toothed plates, roller rotation speed were used test factors, size qualification rate impurity content crushed indexes. Through Box–Behnken design, regression analysis, ANOVA, model between factors indexes established. The results showed that...
