华东交通大学理工学院毕业设计 1 摘 要

该篇设计论文，主要是对饲料搅拌机的形体和搅拌机零件的设计及其工作状态下设计合理性的校核。主要阐述表达了与当前诸多饲料搅拌机所不同的设计理念。这篇论文设计了一台可同时运用两个螺旋搅拌叶高效、合理的搅拌饲料的仪器，这样的一台机器适合各种各样的养殖场，更切近中小型养殖场。这样的饲料搅拌机更适应于当今特种养殖技术的发展趋势，符合市场需求。

总体来说这篇设计通过对于搅拌机的轴、搅拌方式、齿轮的传动的设计校核体现了设计的合理性，文章中还有对于可能出现的问题做了相关的校核检查，所以说这是一篇相对比较全面、完善的设计。

2 Abstract This paper mainly design, design reasonable design and check working state of feed mixerand mixer body parts under. Mainly expressed with current design philosophy of manydifferent feed mixer. This paper designed a simultaneous use of two helix mixing blade,efficient reasonable instrument mixing feed, farm machine is suitable for a wide variety dfsuch, more close to small and medium sized farms. The development trend of feed mixersuch more suitable for today's special breeding technology, to meet market demand.

This article through the overall design for the mixer shaft, stirring, gear design and checkreflects the rationality of the design, there are the problems that may arise to do a checkcheck, so this is a relatively comprehensive, perfect design
