摘要

斗式提升机是一种能够垂直或者一定角度范围内提升物料的一种连续输送机械，其对块状或者颗粒状物料尤其适用。在煤矿、基建、食品等领域有着广泛的应用。斗式提升机的工作过程是利用动力驱动，牵引输送带带动料斗运动，料斗能够不断的提升物料，实现一定距离的运输。斗式提升机整体结构简单、稳定性高、输送能力强，所以应用广泛。

斗式提升机结构中包含了电机、减速器、传动、料斗等设计，能够在较大范围内应用大学所学习的基本知识，所以是一个锻炼总结、运行和理解专业知识的联系。本次设计的是D250型斗式提升机。在设计中对提升机的基本结构和方案等进行了分析，对其传动部分以及主要零部件进行了设计计算，并对关键的零部件进行了计算校核，以确保能够满足使用要求。

Abstract

Bucket elevator is a kind of continuous conveying machine that can lift materials vertically or within a certain angle range, especially suitable for block or granular materials. It is widely used in coal mine, infrastructure, food and other fields. The working process of the bucket elevator is to use the power drive, traction conveyor belt to drive the hopper movement, the hopper can continuously lift materials, to achieve a certain distance of transportation. Bucket elevator is widely used because of its simple structure, high stability and strong conveying capacity.

The structure of bucket elevator includes the design of motor, reducer, transmission, hopper, etc. it can apply the basic knowledge learned by University in a large range, so it is a connection of exercise summary, operation and understanding of professional knowledge. This design is D250 bucket elevator. In the design, the basic structure and scheme of the hoist are analyzed, the transmission part and main parts are designed and calculated, and the key parts are calculated and checked to ensure that they can meet the use requirements.

Key words: D250 bucket elevator; design calculation; structural design
