摘  要

螺旋输送机俗称绞龙，螺旋输送机是一种利用螺旋叶片的旋转，推动物料沿着料槽运送的输送设备，在建筑工地，储粮仓库，制造车间等，并在倾角β＜ 20 °的情况下，输送粉状，颗粒状和小块物料，使螺旋输送机对提高生产工作效率得到了很大体现，本次设计旨在对螺旋输送机进行创新设计，进一步提高它的实用性。
本次毕业设计是关于输送机的设计。首先对输送机作了简单的概述；接着分析了输送机的选型原则及计算方法；然后根据这些设计准则与计算选型方法按照给定参数要求进行选型设计；接着对所选择的输送机各主要零部件进行了校核。普通型输送机由六个主要部件组成：传动装置，机尾和导回装置，中部机架，拉紧装置以及胶带。最后简单的说明了输送机的安装与维护。

Screw conveyor or auger, screw conveyor is a use of spiral blades that rotate, push the material along the chute delivery conveyor equipment, at the construction site, storage, manufacturing workshop, and in the angle < 20 degrees circumstances, conveying powdery, granular and small pieces of material, so that the screw conveyor to raise the production work efficiency has been greatly embodiment, the design of screw conveyer for innovative design, to further improve its practicality.
This graduation project is about the design of conveyer. The conveyor is summarized; and then analyzes the conveyor selection principle and the calculation method; then according to these design guidelines and the calculation and selection methods according to the given parameters selection of design; then the choice of conveyor main parts and components of the school nucleus. Ordinary type conveyor consists of six main parts: transmission device, tail and back to the device, the central frame, tension device and tape. Finally, a simple description of the conveyor installation and maintenance.
Key Words:  screw conveyor, conveyor system, the selection of the design, main components
