The technology of seedling transplanting is agriculture is very important, its main advantage is that can crop growth period of 15 days or so in advance, can avoid the early spring in xinjiang region easily frozen snow, frost and other evil slightly the influence of climatic conditions. In guarantee to the unit number of crop plants such as agricultural demands, increase our survival rate of seedlings, which refer to crop yield and the quality of agricultural products, can significantly reduce the production cost, increase production economic benefit and social benefit is remarkable. This article mainly has carried on the several aspects:Based on the actual situation of xinjiang, we in combination with the unique combination of climate condition and planting technology comparative analysis the advantages and disadvantages of several kinds of transplanting machine and then by comparing literature review analysis of internal and external advanced transplanting machine work and the design process, comb summary to find the suitable for our membrane transplanting cultivation mode of technology and mode of hanging basket type transplanter,through to the present situation of the transplanting machine for foreign study found that in the process of seedling transplanting system integration advantages and domestic transplanter working process often appear problem, determine the technical route in the whole process.Research the pot seedling mechanical properties : transplanting machine directly to do with an object is the pot seedling, the pot seedling mechanical characteristics analysis for transplanting process optimization and the design of the structure has a significant impact, combined with the actual situation of xinjiang indeed chose to use seedling dish, determining the seedling pot seedling basic body size, and then through the analysis of the measurement for pot seedling, the basic three dimensional size research obtained the pot seedling, by measuring the pot seedling and plant compressive properties and compressive properties of pot body, determine the compression characteristic of the pot seedling, contrast and shape material tensile compression feature, similar to the pot body yield strength and the pot body compressive plastic deformation process, and further to explore the physical and mechanical properties of pot seedling on the quality of the plant, avoid appear to hang in the process of planting seedlings, clamp and the phenomenon such as lack of seedlings, through the analysis of the scattered for landing got pot seedling dropping features, provides an important basis for planting apparatus design.The structural parameters of the main parts of the mathematical modeling of reconciliation and design optimization, considering the transplanting operation in the field, transplanting operation time is short, the working strength is big, poor working conditions, membrane transplanting need to punch holes in membrane, the institutions involved in the bare land transplanting is complex, and for influencing pore size of membrane structure parameters in the process of transplanting research is less. Considering zero velocity for seedlings, membrane pore size, planting depth and transplanting planting distance for transplanting process of mathematical modeling and solving, via the for planting and soil model, kinematics simulation was obtained under the condition of the soil by the movement of the planting apparatus of situation,considering the damage of membrane, for the planting apparatus design and has a direct influence the choice of speed ratio, the study of membrane transplanting has great theory value, using the simulation of the prototype technology can better guarantee the rationality of the design, to avoid mistake, provide theoretical reference for the next step of prototype production support and provide parameters for design prototype machines. Transmission system in the whole process, because the planting apparatus of power from the wheel will power transmission to the requirements in the process of planting apparatus of portable and accurate, comprehensive consider to choose the chain, then good distribution in the whole process of transmission structure. At the same time in the process of planting the carrier too much will make the frame of transplanting machine produce very big load, ultimate role in hanging position, through to the analysisand improvements to the main girder of the suspension system, ultimately determine the structure of the hanging position and size. But the working process of the transplanting machine is cultivated and the impact of the ground, if the quality of mechanical differences will make planting quality is affected.key parts of the transplanting machine manufacturing, the working process of the transplanting machine is due to the impact of soil and planting apparatus, the working process of the dynamic load is higher for the machine parts in quality requirement is high also, under the concept of green manufacturing now through the selection of manufacturing methods and process, reduce the waste in the whole manufacture process and reduce the cost. Due to the specificity of the planting process for the demand is higher, the quality of the machine itself is also more limited machine price advantage, so in the manufacturing process through the research and development process of new technology to speed up the machine to reduce costs. Through the analysis of the machine, according to select parts more complex processing is difficult, because the quality of each batch will appear larger fluctuation, we select the appropriate process makes the batch quality guaranteed, and the process is analyzed, the resulting composite parts. |
