The CAD Of New Type Tobacco Transplanter And Analysis Of Plant Part

Tobacco is one of the most important economical crops, plays an important role in agriculture production and it is one of the most important economic sources to the state and the local renvenue.At present,Chian is the leader in the production of tobacco in the world,account for world production of 1/3.In our nation,the tobacco planted acreage has up to 11531km2.The planting process of tobacco is transplanting after the seeding.By transplant the seeding can extend the season of the crops growing.Not ensure the number of plants per mu only,but also ensure the plants orderliness more stonger.So enhance the output.The transplant can againsts various pests,diseases,wind,lower temperature and arid effectively during the seeding growth stage.Control the environment of the seeding groeth and increase the state of the seeding survival.Seed saving can amount to 30% to 50%.Though there are many benefits of transplanting cultivation,there are many high requirements for the transplanting of tobacco. Required to maximize the planting of tobacco seedlings to ensure the uniformity of lines and line spacing consistent. Too dense or too sparse will have a great impact the quality of plant growth and later on tobacco products.For lang time,using traditional methods of transplanting by hand,a farmer can transplanting only 333m2 one day. It does not include fighting ditch,fertilizer,tectorial membrane of the time-consuming.Not only labor intensive and lower productivity,but also the quality of transplanting is poor. Farmers have become more and more urgent demands of the mechanized transplanting of tobacco.The use of tobacco transplanting machine for transplanting can contral the transplanting cultivation of planted crops and line spacing strictly.Transplanting machine can complete a series processes of trenching, transplanting, overburden,fertilization, repression.Transplanting can significantly reduce the labor intensity of farmers,fighting more time for spring planting and increasing the efficiency of crop cultivation greatly.The thesis study some home ang forigen country's structural characteristics of crop transplanting machines and design a new type of tobacco transplanting machine.Carried out a detailed theoretical analysis and design described on the overall mechanical structure,the key components-investment seeding institution and the working principle of the planting.And the use of SolidWorks 3D design software for the platform.Draw the three-dimensional model of transplanting machine and drawings.Use the COSMOSWorks plug on the application of the key structure components transplanter crankshaft and bear component-bearing pedestal type structure of the FEE analysis in order to determine the reliability of the process of its movement.Use the COSMOSMotion motion simulation analysis software application on the agency made a motion simulation for the plant body. View and analyze the track of seedlings, come forward speed of the tractor and the best matching range of crankshaft speed.Calculated by mathematical movement of tobacco transplanting machine in the best position to put the seeding.
