Ill, Fourier based separation technique for shape grading of potatoes using machine vision, Transactions of the ASAE 1995,38:949–Title the design of the threewheeled cart gearbox for the agriculture uses AbstractIn car spread move department, the gearbox is used to change to launch the machine spreads to drive a round ascends of turn the ju with turn soon, the purpose works within the scope of originally start, climb the po and make a turn, accelerates etc. Every kind of drive work things descend make car acquire lead the dint differently with speed, make launch the machine at the same time in the most beneficial work things .Primarily from bee to spread to move the organization soon with manipulate the organization constitute, in recent years, the gearbox designs to have the direction to manipulate the trend that direction development automatically. spare parts is synchronously the design choice of the machine.What this graduate design is an agriculture to bee with the threewheeled cart soon box, primarily is to according to the multifunction agriculture in a type 7Y975A2to bee with the threewheeled cart soon a construction to have known the parameter that make selection, pute the choice design the assemble diagram needed in the process with the spare parts a draw the spare parts diagram according to these parameterses to assemble the diagram with the the appropriate improvement to the technique between traditional design method, step and design in design process, to attain the creative purpose.Key words: Gearbox Spread to move the ratio Cylinder Straight Wheel gear
