Corn By One Big Ridge Two Rows Deep Fertilization Seeder Design And Experimental Research

Corn is the main food crops in LiaoNing, but long-term traditional cultivation mode, The stiffness of the long-term cultivation pattern lines into the plough is bad for the growth of crops. In addition, the machine enter land many times compacted soil, reduce the permeability and porosity. And increase power consumption, improve the operation cost. Based on this, this study combines the advantages of one big ridge two rows planting patterns, Developing a machine has a deep furrow, fertilizing and seeding function, To solve the above problems, the effectiveness of the improved fertilizer, has a certain practical significanceThis paper on the basis of Deep tillage and ridging fertilizer applicator, Designed and developed by modification, a Corn by one big ridge two rows deep fertilization seeder, Retrofit design of the main work includes subsoil fertilizing parts, planting design, the whole ridge contour connection parts design, key support components analysis, optimization and machine manufacture, Based on the field performance were tested, Through to the seeding depth, planting distance measurement and statistical analysis of the leak seeding and replay, evaluate the performance and stability of the machine, Through the split groove depth and ridging parameters measurement, verify the effectiveness of subsoil fertilizer application components and the whole ridge components, Through barriers, test the feasibility of parallel four-bar copying connecting mechanism, The experimental results show that the developed prototype meet the design requirements, various test indexes meet the requirements, meanwhile test the tractor forward speed influence on planting distance, it is concluded that the machines when traction speed 0.4 m/s seeding effect is best.The machine within a job schedule to complete the soil deep loosening, layered, ridge ridging fertilizer, sowing covering and so on many homework. Machine does not need to repeatedly into the job, protecting the soil structure, soil can absorb more moisture and nutrients, is more advantageous to the growth of crops. Save fuel, not only reduces the cost but also protect the environment. This way of joint operation improves the working efficiency, reducing the labor input, to achieve the purpose of reduce cost increase efficiency.
