Design Of All-round Adjustable Deep Loosening Machine

At present the vast areas of northern China, is still to a large ridge to the main crop, stubble every year on the land, plowing, plowing, ridging and other operations, due to many years of farming, forming a thick bottom plow. Plow pan hindered the growth of crop roots, soil water damaged topsoil, fertilizer, gas, heat and chemical relationship between the modern technology of deep pine conservation tillage technology as a system of minimum tillage practices, the use of subsoiling equipment to enhance topsoil without turning the soil, breaking the plow pan, compared to the control of soil 3, the coexistence of topsoil structure to create actual situation, to reduce soil erosion, increase soil water storage drought resistance.This paper describes the status of subsoiling equipment, full-subsoiler types and tillage shovel in the form of deep pine technology is analyzed. Subsoiling operation may break the plow pan, deepening topsoil, topsoil structure formation of the coexistence of actual situation, the crop development to create a good soil conditions.To increase grain yields and meet the needs of Jilin Province, deep plowing subsoiling in autumn, made a full-adjustable subsoiler design issue was in October 2008 completed the machine's design, production and promotion, while the completion of the provincial level product identification and promotion of identification, application and obtain a national utility model patent (Patent No.: ZL 200820072070.8).This article is designed, mainly using three-dimensional mapping software designed INVENTOR10.0 wide subsoiler adjustable three-dimensional model, then apply the ANSYS finite element analysis software for mechanical analysis of key components, compare the force parameters on the subsoiler performance, through computer simulation and field test of subsoiling on subsoiler with four spade, shovel 5,6 shovel operating performance under test, to further improve the adaptability of subsoiler and power equipment parameters to meet the cost increase subsoiler, saving and synergy of purpose.This conclusion mainly in the following areas:1. By adjustable wing shovel and rack with the adjustment to achieve full subsoiling subsoiling and the interval between two operating methods of conversion, to complete a row subsoiling soil preparation work.2. Detected by computer simulation and actual field test show that the designed equipment to be Industry through the performance, be buried performance, stability and transport of deep tillage and gap indicators can meet the design requirements.3. Subsoiler field test with 4 spade, shovel 5,6 shovel operating performance of state tests to determine the subsoiler dynamic matching parameters, while the suspension has been verified. Aircraft flying through different combinations of connections can be used with different models of tractor.4. Machinery shovel with adjustable wings, so full of deep loose performance. Sufficient to break the plow pan, Watergathering ability to improve the soil for the semi-arid areas of conservation tillage operations and Jilin Watergathering subsoiling wheel turned 3 years implementation of the polic provides a reliable operation of subsoiling equipment.
