摘要刮板输送机是在封闭箱体内，借助于运动着的刮板链条连续输送粉尘状、小颗粒及小块等散状物料的连续输送设备，可以水平、倾斜和垂直输送。

针对当下国内麦芽输送刮板机的普遍存在的问题，在机器的制造方面还欠缺很大柔性制造，为了适应不同的需求，刮板机的设计费时费力；所以我们进行了方案的概述，将采取的措施，和一个实施的方案，最后确定方案的选用。

在现有的麦芽输送刮板机的型号中选择一种型号来模拟工厂的需求，然后来进行一系列的设计包括：机体的设计，传动输出的设计，刮板链条的设计选型，轴和链轮的设计校核等，在校核的方式方法上面，我还采用了有限元分析的方法，与传统的安全系数分析法不同的是，有限元能够更加直观的看出轴、齿轮的受力变形的地方和大小，从而能够模拟和改进设计的方案。53183

对刮板机的参数化进行了详细的论述，参数化通过模块化和系列化来一起实现，通过零件的系列化，使得部件的模块化，让它能够具有高柔性，适合与不同的选型场合，能在最短的时间内，组装出一个新的机器，不需要再进行定制，费时费力，不适合市场的需求。

Abstract Scraper conveyor is in an enclosure, by means of moving the scraper chain conveyor dust-like, small particles and small pieces of bulk materials such as continuous conveying equipment, can be horizontal, inclined and vertical transmission.

For the moment the domestic malt scraper conveyor ubiquitous problem in the manufacture of the machine still lacks a large flexible manufacturing, in order to meet different needs, scraper design laborious; Therefore, we carried out an overview of the program, will be taken measures, and an implementation plan to finalize the program of choice.

The existing models malt scraper conveyor select a model to simulate the plant needs, and then to carry out a series of design include: airframe design, the design of the drive output, scraper chain design and selection, shaft and sprocket design check and so on. Ways and means in checking the above, I also used the finite element method, and the traditional safety factor analysis method is different, finite element can be more intuitive to see the shafts, gears where the force deformation and size, thereby able to simulate and improve the design of the program.

Scraper parameterization for a detailed discussion of parametric modular and series come together to achieve, through parts of the series, making the modular components, it can have a highly flexible, suitable for use with a different selection occasions, in the shortest period of time, assemble a new machine, do not need to be customized, time-consuming, not suitable for the market demand.
