“…Using a cutting ring, soil samples were taken from 10 different locations with a sampling depth of 5 mm, 10 mm, and 15 mm. The average moisture content of the soil was measured to be 17.6% (dry basis) using a drying method, and the average bulk density of the soil was 1.51 g/cm 3 . In the soil bin simulating the field where corn straw was crushed and returned to the field, the density of straw paving was 0.5 kg/m 2 .…”

Understanding the soil-straw disturbance pattern of the key component parameters of the straw mixing winged chisel plow is the key to designing and optimizing the straw mixing winged chisel plow (a chisel plow for mixing and mulching straw). In this study, a straw-soil-winged chisel plow interaction model was established, and the working principle, key components of the winged chisel plow were determined based on soil bin experiment and theoretical analysis. Discrete element method (DEM) was used to study the influence of disturbance pattern of key components of the winged chisel plow on soil-straw displacement, straw mixing rate and draught force. The results show that the main components of the winged chisel plow that affect the operating efficiency of the implement are the soil lifting plate height, the wing mounting height and the wing width. The height of the soil lifting plate affects the efficiency of the winged chisel plow in secondary disturbance of soil-straw and its own performance in turning over soil, with an optimal range of 110 mm-170 mm. The installation height of the wing mounting mainly affects the position of the soil lifting plate in the soil layer. In order to achieve the best operating effect, the position of the soil lifting plate needs to meet the "lower lifting and upper turning" requirement. The optimal installation height of the wing mounting is 95 mm-145 mm. The width of the wing mainly affects the working width of the implement, and its optimal value is 180 mm-220 mm. The width of the wing mainly affects the working width of the implement, and its optimal value is 180 mm-220 mm. The established simulation relative error is within 12.60%, which can better study the disturbance pattern of soil-straw. This study may provide a reference for optimizing and designing wing-type chisel plows and subsoil shovels.

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