Structure Optimization And Performance Test Of The Suspension Reversible Deep Plowing Plow

Mechanization of agriculture is an important part of the modernization of agriculture and the development of agricultural production, it can not only improve labor productivity, but also is an important means of improving yields. Since ancient times human beings in order to survive and develop, are constantly creating and improving the various production tools to improve labor efficiency, reduce labor intensity and improve labor quality. Tillage technology is an important aspect in the history of human development, it promoted the development of human civilization, from the original slash and burn to plow generation, the pace of exploration of humanity in the process of agricultural development has never stopped. Deep plowing tillage is a technique of loose layer soil compaction, tillage depth can reach more than 30 cm, its main role is to break the plow pan, increase the depth of tillage layer, it can bury top soil and vegetation residues that contain pests, improve the physical properties of the soil and the quality of land planted, conducive to crop growth and increase crop yields.This article aimed 1LYF-155 type hydraulic flip plow plowing of plow positioning mechanism breakage and wear a serious issue, put forward a structure optimization configuration for the flip positioning mechanism and the primary and secondary plow spatial structure optimization, summarized as follows:(1)Through the three-dimensional SolidWorks software established a three-dimensional model of flip positioning mechanism, utilized ANSYS software to analysis flip positioning mechanism statics and proposed three optimized improvement programs for the flip positioning mechanism. Combined with processing technology of deep plowing plow, and finally selected the optimized safety factor of 2.30 straight board positioning reversing mechanism.(2)For the plow wear problem, configure a deputy plow in the left rear of the main plow. Deputy plow tillage depth is 30 cm, the main plow tillage depth is another 30 cm based on the deputy plow, that formed a tillage farming way of the primary and secondary hierarchical plow to reduce the load on a single plow. By ANSYS-LS / DYNA optimized for both the front and rear plow configuration simulated cutting earth comparative experiments. In total tillage depth of 60 cm, the optimized configuration to the primary and secondary forms of deep plowing plow tillage load is 86.6 MPa and before optimization tillage load is 67.1MPa, plow tillage load reduction is 29.1%.(3) Conducted field performance tests of improved implemented deep plowing plow according to the national standard test method GB / T 14225-2008 in the plow and NY/T 742-2003 plow tillage quality. The test results: The average depth of deep plowing plow is 60.59 cm, deep tillage stability coefficient in the same conditions is 98.656%, coefficient of variation is 1.344%. The width average of deep plowing plow is 64.79 cm, width tillage stability factor is 97.921%, the coefficient of variation is 2.079%. Vegetation and stubble coverage below surface after deep plowing plow of average is 91.87%; The vegetation and stubble coverage after soil tillage depth below 8cm with an average is 71.84%. Flip in place is 100%.
