The design of the legacy from the old system of starting seedlings in the transmission system and executing agencies have done on a lot of improvement. The machine can produce per hour legacy of 4000, can be widely applied to corn, vegetables, fruits and other seedlings of the legacy system. The aircraft uses a single-phase motors to power source, can be used in the vast rural areas, need not worry about a higher power voltage problem. In a more detailed design of the system for the seedlings Bowl drive system and implementing agencies, the various parts to do a specific size of the structure design, and in the larger load of spare parts for the precise calibration. Including gear, pulley, and axle bearings and other parts of the check. The extensive use of the aircraft design standard parts, greatly reducing the workload of the design and lower manufacturing costs and manufacturing cycle. Main design elements include: the determination of the project, choice of Motor and the speed of every axial, the calculation of power and torque, the design and calculation of the belt or gear and the Bevel gear, the smallest diameter of axis, calculation to the size of belt wheel and gears and Bevel gear and protracting the drawing of the project and the assemblage and the part.
