Design of the legacy of seedlings
Abstract: The old system of seedlings from the legacy of improvement in the briquettes machine, the size, structure complex, high cost and low efficiency. 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.

毕 业设计(论文)使用的原始资料(数据)及设计技术要求：
设计一制育秧钵机，要求：
（1）按规定的尺寸制出育秧钵；
（2）每小时生产3000个左右；
（3）结构简单，体积小，拖动功率小，维修方便，造价低。
用途
育秧钵机是一种制作培育秧苗钵体土胚的机器，该机可替代人工自动制作秧钵，具有生产效率高，结构简单，稳固可靠，容易操作等特点。
育秧钵是一种培育秧苗用的土胚，它能使秧苗在育秧期有足够的养料及秧苗成长后能方便的移植到田间栽种。育秧钵由配有各种肥料的土壤做成圆柱形状并在上端挖一个凹孔使之成钵状。使用时将种子播在凹孔中，用土覆盖，待秧苗成长后连育秧钵一起移到田间栽种即可。
