The Rearch And Optimization Desing On Automatic Potted-seedling Transplanter Of Cycloid Gear Trains In Upand Field

In the northeast region of China, seedling raising technique can effectively avoid the influence of climate on crops and increase the multiple cropping index. However,The main type is the semi-automatic transplanting mechanism both foreign and domestic which is artificial seedlings, inefficiency, high labor intensity.The author’s research group is according to the situation in agronomic requirements, propose one kind non-circular gear planetary gear train upland field all automated transplanting mechanism, and make it in travelling transplanter and high velocity transplanter’s preliminary transplanting mechanism optimization method(Software copyright registration number.2013SR104893). According to the actual work situation,building optimized objective function. Then making use of man-machine interaction, calculating the numerical optimization goals.The transplanting mechanism in this paper still use the rice transplanter’s moving-box mechanism. The modern design method that is according to dry crop agronomic requirements, analyzing the system of semi-automatic transplanting mechanism is a modern design method of structure innovation (taking an example of corn), parameter optimization, virtual manufacturing, virtual simulation. The main research content is as follows:(1) Collecting and analyzing the transplanting mechanism’progress and the subject of research Significance both foreign and domestic, propose some thought of domestic transplanting mechanism. This paper puts the structure of rice transplanter into the hinterland, proposes the trace that is similar with "8", then indicates the trace at every stage. Making an experiment in corn seedling’s taking out force and pulling strength which can feasibility verification mechanism and making a capability evaluation.(2) To propose the roulette non-circular gear planetary gear train transmission mechanism, and to make a concrete analysis in roulette gear mesh character and the kinematics theory model.In order to develop kinematics parameter optimization software theoretical foundation, building transplanting mechanism planetary gear train angle of the theoretical system which combine with the operating principle of roulette rotation transplanting mechanism.(3) According to the actual work situation and the theory analysis, to build Kinematics optimization objective function and combine with high velocity transplanter’s preliminary transplanting mechanism optimization method. To apply visualization programming software Visual Basic6.0, develop a kinematics optimization software. Optimizing the parameters through man-machine interaction. Making use of output area and menu bar check and save optimize parameters.(4) Integrating the problem of others physical prototype in debugging and the experiment, To accomplish the non-circular gear planetary gear train transplanting mechanism constructional design by using the AutoCAD; To build virtual prototype by using the SoldWorks and utilizing the ADAMS to emulate.Through a design system package, verify the rationality of the virtual prototype.(5) After virtual experiment,in order to realize marketization, author propose optimization software further optimizing and two-dimension or three-dimensional drawing design philosophy.In order to all automated transplanting mechanism self-development, provide a development mentality.
