设计简介
摘 要
本设计主要论述的是风力搅拌机的结构设计，该设计旨在利用风能直接搅拌代替以往人力或电机作业。此构思来源于生产实际，是根据节约能源，有效利用环境和保护环境这一主题而提出的新的设计构想。
本设计的主要内容包括：风能接收装置的设计，中间传动系统的设计，混凝土搅拌机的设计，以及主要零部件强度计算等。
该设计中风能接收装置采用上风、水平轴式布置，NACA翼型，风能直接作为机械动力，通过传动系统将动力传递至搅拌机。中间传动系统采用先增速传动，目的是提高系统的传动效率，然后再减速传递，达到滚筒要求的转速。搅拌机采用锥形反转出料式，其中滚筒传动采用齿轮——齿圈传动，料斗升降装置采用钢丝绳卷筒作用，卸料方式为倾翻卸料，待混凝土搅拌均匀后反转出料。并在原有的基础上设计了必要的调速、制动装置，即通过锥齿轮改变机头方向，在需要的时候垂直或平行于风向，以使滚筒转速保持稳定。
该设计最大的特点是节能、环保。并且结构简单，拆装便利，移动方便，投资少，建设快，对建筑施工有极其重要的意义。

ABSTRACT
This design mainly discusses the contracture of the wind power mixer, and the aim of the design is using the mixing of the wind power to displace manual labor and electrical work. This idea comes from the practical working, designing the new idea with the theme of saving energy, utilizing environment and protecting environment effectively.
The main content of this design includes the design of wind power receiver device, the design of middle transmission system, the design of concrete mixer, the analysis of the main assemblies and the force calculation.
In this design, the wind power receiver device adopts windward, horizontal axial arrangements, NACA wing section and the wind power as mechanical force to transmit the power to mixer through transmission system. The middle transmission system adopts accelerating speed first, the aim is to improve the efficiency of the transmission, and then decelerating the transmission to reach the cylinder’s need. The mixer adopts taper reversing system, the cylinder adopts gear--gear transmission, the system of rising and falling adopts steel cable, discharging materiel with inclination after the concrete is mixed averaged. The design adds the essential speed governor and braking system namely changes the direction of aircraft nose with gear, vertices and parallels with the direction of wind in order to keep the stability of the cylinder.
The most important feature of the design is to save energy and protect the environment. The structure is simple, easy to disassemble, easy to move, less investment and faster construction, which is of great significance to construction.
Key words：Wind stirring; concrete; energy saving; environmental protection
