我国的谷物生产及消费量十分巨大，自2013年以来,我国粮食总产量连续九年增长,其中谷物(稻谷、小麦、玉米)约占粮食总产量的九成。全国粮食单位面积产量5452.1公斤/公顷(363.5公斤/亩),位于世界第三，仅次于世界第一的美国和世界第二的加拿大，而全球每年13亿吨食物被浪费，亚洲谷物浪费尤突出，联合国粮食及农业组织11日发布的一份研究报告显示，全球食物浪费现象惊人，不仅造成重大经济损失，而且严重危害人类赖以生存的自然资源。
为了解决这个问题,我们开发了一套投料、干燥、杀菌、存储在一个新的粮食存储系统中，一种新型的粮食存储系统是适应农业发展，该技术将作物浪费现象降到最低，粮食存储率和利用率提高，新技术越来越得到人们的欢迎，也带来了科技人员的关注。
本次设计主要是对谷物存储系统这种机器设备进行结构分析以及一些必要的计算过程说明，通过对环模的内径以及外径等众多因素的分析整合，从而设计出最为合适的尺寸以及一些必要的参数要求，再者通过solidworks绘图软件，对设计的产品进行3维立体的构图之后，完成总体的装配，与此同时，在这种情况下为了提高干燥的能力，选用的是螺旋式的干燥等装置。最后从现实生活中的实际生产情况来说，将整体的尺寸进行合理的优化并最终确定一些必要的设计要求参数，使储存设备能够运转工作的更高效更能使利益最大化。

ABSTRACT

 
Grain production and consumption in China is very large, since 2013, China's total grain output growth for nine years, with grains (rice, wheat, corn) accounted for about ninety percent of the total grain output. National grain yield per unit area of 5452.1 kg/ha (363.5 kg/mu), located in the third world, second only to the top of the world the United States and Canada, the world's second, and each year 1.3 billion tons of food wasted, Asian corn waste particularly prominent, the UN's food and agriculture organization (fao) 11, according to a study released global food waste phenomenon, not only cause great economic losses, the survival of humans and cause serious damage to natural resources.
In order to solve this problem, we developed a set of feeding, drying, sterilization, storage in a new grain storage system, a new type of grain storage system is to adapt to the agricultural development, the technology will crop waste to a minimum, grain storage rate and utilization rate of increase, new technology, more and more get the welcome of people, also bring the attention of the scientific and technical personnel.Also through solidworks drawing software, after three dimensional composition of the design product, completing the overall assembly. At the same time, in this case, in order to improve the ability of the material, it is a spiral conveyor.
This design is mainly to grain storage system this kind of machine equipment for structural analysis and some necessary calculation process, based on the inner and outer diameter of the ring die with the analysis of many factors such as integration, so as to design the most suitable size, and some necessary parameter requirements, moreover through solidworks drawing software, the design of the product after 3 d composition, complete the general assembly, at the same time, in this case, in order to improve the ability of drying, selection of drying device is a spiral. Finally in the actual production conditions in real life, will be the size of the whole reasonable optimization and ultimately determine the necessary requirement of design parameters, the storage devices can operate work more efficient and to maximize the benefits.
