本文设计了鱼塘养殖自动投饲料机。本文首先分析了鱼塘投饲机的国内外现状及发展趋势，介绍了现有主流投饲机。接着根据现有投饲机的特点及要求，拟定了两种可行投饲机方案，为满足间歇性投饲要求，选择了曲柄摇杆机构作为送料机构的方案。接着对投饲机进行了详细设计，并绘出装配图及零件图。
最后对投饲机进行零件三维建模及虚拟装配，验证设计的合理性及干涉。最后进行运动仿真，所设计的投饲机结构简单，维修使用方便。

ABSTRACT
China is the world's first aquaculture country, along with the rest of the breeding scale unceasing expansion, the use of machinery instead of manual feeding has been generally recognized. Specialized households aquaculture fish feed in the feeding, most of the artificial material throwing method. Feeding of low degree of mechanization, as labour costs increased, becomes one of the restricting the development of aquaculture in our country link.
Based on the above reasons, this paper designed the aquiculture automatic feeding machine. This paper analyzed the domestic and international situation and development trend of fish feeding machine, introduced the current mainstream of feeding machine. Then according to the characteristics and requirement of the existing feeding machine, designed two kinds of feasible feeding machine, in order to meet the requirements of intermittent feeding, the crank rocker mechanism as the feeding mechanism scheme. Then the detailed design of the feeding machine, and draw the assembly drawing and part drawing.
Finally, the 3D modeling of parts and virtual assembly of the feeding machine, verify the rationality of the design and interference. Finally, the motion simulation of feeding machine, the design of simple structure, convenient repair and use.
Keywords: aquaculture, feeding machine, crank rocker, hopper

第一章绪论
1.1课题背景
我国是世界上第一水产养殖大国, 1993年养殖水面达474. 7万公顷,养殖总产达957万吨。除投喂鲜活饲料和某些鱼类的特种饲料外,人工投喂颗粒饲料是我国养殖生产中的主要喂养方式。
