Modular Machine Design And Research Factory Seedlings

With the continuous expansion of rice cultivation area, efficient mechanized rice cultivation is needed to solve the problem.Mechanized seedling transplanting technique can reduce the impact of natural disasters on seedlings, reduce labor intensity growers to ensure quality planting operations, to increase production, the purpose of income, has now been widely adopted. The mechanization of seedling transplanting technology is an important part of seedlings, transplanting seedlings have a direct impact on the results.The current low level of automation domestic seedling planting machine, so it has very important significance for seedling planting machinery research. For lack of seedlings in the research and design of mechanical needle exists, the virtual prototype technology into seedling mechanical design and development field, you can greatly improve design speed, lower costs for the development of industrialized seedling machine provides an effective way.Text of the main square and from the following studies:This article is based on the basic design principles factory seedlings machines on the market as a whole to improve machine type factory seedlings, soil device for laying machine modular factory seedlings, planting the device, the device analyzes the casing design, the use of three-dimensional parametric CATIA design software for the various components were solid modeling, geometric parameters obtained for each component-And completed the whole machine assembly factory seedlings and interference checking, very intuitively shows the factory seedlings machine assembly of all components for the development of the physical path of the assembly to provide a reference, effectively improving the design speed.In order to fully understand the key components factory seedlings machine stress condition in rice planting process, using ANSYS for planting agencies finite element analysis.By analyzing the seeding mechanism and its relatively stress and deformation, and ultimately determine seeding shaft with a hollow structure, weight loss of 34%, provided the basis for the physical manufacturing;In order to understand and master the performance modular factory seedlings sowing machine, through tests to determine the coordination between the various units of the dynamic parameters of the seeding density, sowing when the motor speed is the maximum amount of 52g/disc is 1650r/min, when the speed again increases or decreases, the seeding rate is also reduced when the speed reaches 2400r/min, the seeding rate of only 29.6g/disc.
