Its performance advantages in the course of transmission without injury grain tablets, transmission capacity and transmission distance great; Throughout the belt can be on the loading and unloading, transport level can also be tilted transportation; can transport bulk grain, but also the transportation of food packaging, low power consumption, reliable operation and easy management, work without the noise. Food conveyor machinery is not only able to make the production process of connecting to form Production Lines. And the transportation of materials at the same times other technology operations. Also in conjunction with other control measures to control the flow of materials and to control the entire production rhythm and speed purposes. Using advanced design method to carry though whole design and trade-off analysis; accelerate develop speed, reduce design cost, consequently improve competitive ability of this kind of cargo, and accelerate belt conveyor’s widely spread and use. Key words：transportation machinery；transport capability；conveyor；control目 录 摘 要 I Abstract II 第1章 绪论 1 1.1 选题的目的和意义 1 1.2 输送机概况 1 1.2.1 输送机械在工业中的应用 1 1.2.2 输送机国内外发展现状及趋势 2 1.3 设计的主要内容 3 第2章 总体方案论证 4 2.1 机械部分的方案的论证 4 2.2 传动方案的确定 5 2.3 其他机械部件的确定 6 2.4 总体结构的确定 7 第3章 输送机的设计计算 9 3.1 输送机的计算 9 3.1.1 带宽的计算 9 3.1.2 输送带宽度校核 10 3.1.3 输送带最大的物料横截面积 12 3.2 输送能力的计算 13 3.3 圆周驱动力与驱动功率 13 3.3.1 圆周驱动力 13 3.3.2 传动滚筒轴功率的计算 19 3.3.3 附加功率计算 20 3.4 电动机功率计算 20 3.5 输送带张力计算 2
