育秧制钵机的结构设计
摘要
老式育秧制钵机由蜂窝煤成型机改进得来,体积庞大,结构复杂,成本高,效率低。本设计从老式育秧制钵机出发,在传动系统和执行机构上都做了很大的改进。本机每小时能生产3000个钵体,可广泛应用于玉米、蔬菜、瓜果等秧苗的制钵。
该机采用单相电动机做动力源,可在广大的农村使用,不用担心需要较高的动力电压的问题。文中较详细的设计了育秧制钵机的传动系统和执行机构,对各个零件做了具体的结构尺寸设计,并对受载荷较大的零件进行了精确的校核。包括齿轮、带轮、轴和轴承等零部件的校核。
该机的设计大量运用标准件,大大缩短了设计工作量和降低了生产制造周期及成本。主要设计内容有:方案的确定;电机的选择;各轴的转速、功率和转矩计算;带、齿轮、及锥齿轮的设计与计算;轴的最小直径;带、齿轮、及锥齿轮的尺寸计算以及方案图、装配图和零件图的绘制。

Abstract
The utility model has the advantages of large volume, complicated structure, high cost and low efficiency, which is improved by the b briquette forming machine. The design from the old system of seedling raising bowl machine, in the transmission system and the implementation of institutions have done a lot of improvement.
The utility model can produce 3000 pot bodies per hour, and can be widely used for making bowls of corn, vegetables, fruits, etc.. The machine uses single-phase motor as power source, can be used in the vast rural areas, do not worry about the need for higher power voltage problems. In this paper, the design of the transmission system and the executive mechanism of the seedling bowl making machine is designed in detail, and the structural dimensions of each part are designed. Including gears, pulleys, shafts and bearings and other parts of the check.
The design of a large number of standard parts, greatly reducing the design workload and reduce the manufacturing cycle and cost. The main contents are: design scheme; motor selection; computing speed, power and torque of each shaft; design and calculation of belt, gear and bevel gear; minimum diameter shaft; belt, gear, bevel gear and size calculation and program diagram, assembly drawing and parts drawing.
Keywords:Seedling raising bowl making machine; Bowl; Drive system; Executing agency
