The Design And Research On Multi-function Maize Planetary Gear Train Transplanting Machine

Transplanting technique can extend the agricultural crop growth cycle, it is well known. To solve the problem of spring drought brought to corn, corn pot seedling transplanting can be a very good use of photosynthesis, thus improve the farmers’income. Corn pot seedling transplanting although at home has been trying for a long time, but no breakthrough type mechanical design and development. Domestic models mainly semi-automatic, artificial seedlings, farmers fatigue; Foreign counterpart of equipment, the equipment is more complex, institutions, the introduction of foreign equipment is expensive. So design a new type of automatic maize transplanting machinery has become a pressing demand.Based on the present status of corn pot seedling transplanting machine at home and abroad to make a careful study, analysis of the pros and cons of various types of transplanting machine, on the existing mechanical transplanting research platform,developed the corn pot seedling transplanting machine core institutions, the agency can be individually as taking seedling mechanism, automatic take miao; The supporting device through the optimization of the structure parameters, CSCL seedling and planting seedlings functions in an organic whole, namely take seedlings and planting seedlings movements are performed by the set of institutions. The corn automatic pot seedling transplanting mechanism has simple structure, reliable operation, can dry field open hole function independently. Has openly invention patent (201310129093.3). This article main research content is as follows:1. Refer to the actual demand and mentor requirements, formulate the target trajectory, and adjust their attitude to make it fit in with actual demand. Corn pot seedling transplanting mechanism invented to meet the requirements, accurate and reliable finished corn transplanting mechanization, the efficiency will be much higher than other semi-automatic transplanter corn.2. Understand physi CAL pot seedling transplanting test rig, of corn seedling and BoPan specifications for actual statistics.3. Lateral non-uniform design agency sent seedlings, use of constant and variable speed helical gear shaft are two ways to achieve a non-uniform seedling box. Create a mathematical model of the screw shaft equation of the seedling box moving the slider to drive the process in the two ways, the feasibility of a non-uniform seedling delivery mechanism through experiments.4. Through the transmission characteristics of the design of the planetary gear train African round analyzed VB-based visualization platform, developed a unified analysis transplanting and planting agencies and institutions optimized software, the research group will be the first time in two fusion in a planetary gear train operation section. And through human interaction features of the software to optimize the design of the mechanism of this article.5. Out of the institution for the optimization of two-dimensional modeling, design of key components. 6. Corn seedling transplanting machine build three-dimensional model with UG, and its virtual simulation. Output of the simulation results, the target trajectory and attitude to compare, analyze the reasons for the error.
