Abstract
[Objective]At present, the soil breaking in the domestic corn strip ploughing operation has the problem that the soil is finely broken after rotary ploughing, and the moisture loss is large, which is easy to cause dust on the topsoil of the farmland, resulting in serious water and soil erosion. At the same time, the compaction of soil can not adjust the pressure according to the change of soil moisture, resulting in soil moisture can not meet the needs of crop sowing, which affects the quality of sowing. Therefore, a strip-till cultivator combining disc harrow crushing and variable pressure compaction operations was designed. [Methods]A static analysis of the drive shaft was carried out to determine the reasonableness of the design. The influence of the number of counterweight blocks on the compression strength was tested, and a three-factor, three-level orthogonal test was conducted with the travelling speed, harrow depth and harrow blade spacing as the test factors, and the soil crushing rate as the test index. At the same time, a quadratic regression orthogonal test was carried out to verify the combination with travelling speed, suppression strength and harrow depth as test factors, and soil firmness and surface flatness as test indicators.[Results]It was determined that a compressive strength of 22.1 kPa could be generated when three counterweight blocks were configured, which met the conditions for corn emergence. The main influencing factors of soil crushing performance were travelling speed, harrow blade spacing and harrow depth; the optimal combination of working parameters was travelling speed of 3 km·h-1 , harrow depth of 10 cm, and harrow blade spacing of 140 mm, then the soil crushing rate was 73.15%, which was the optimal crushing effect of this experiment. The main influencing factors of soil firmness and surface flatness were obtained as compression pressure, harrow depth and forward speed; the optimal combination of parameters was determined as forward speed of 3 km·h-1 , compression strength of 21 kPa, harrow depth of 8 cm, and then, the soil firmness was 53.4 kPa, and surface flatness was 2.7 cm, which were in line with the relevant standards in the industry.[Conclusion] This study can provide a reference for the design and optimization of soil crushing and compaction strip-tillage implements, and lay a foundation for improving the effectiveness of maize strip-tillage operations.
