1、 - I - 摘摘 要要 本次设计以原有的煤仓疏通机为基础，对原有的煤仓疏通机进行全面分析，为了适应 新的环境，对其中的部分设计进行了重新改进设计，使煤仓疏通机改进后既满足加工要求， 结构又简单、方案合理。 本文分别介绍了各种不同结构形式煤仓的作用，煤仓的分类，常见的堵塞事故，分析 了煤仓堵塞事故发生的原因和堵塞的机理。针对煤仓堵塞问题，依据前期研究的基础，对 煤仓堵塞疏通装置进行总体说明，包括疏通装置的总体简介，疏通装置的结构与工作原理。 疏通装置主要部件的设计为本次设计重点，因为它的设计质量直接关系到煤仓疏通机 成功与否，设计包括对煤仓疏通机的一些主要零部件，包括增速装置，储能装置，缓冲装

2、 置，角度调节装置和对螺栓连接的设计与较核等。 关键词关键词：煤仓疏通机 增速装置 储能装置 缓冲装置 角度调节装置 - II - Abstract The original design of the coal bin to the clearing machine, based on the original machine to clear the bunker for a comprehensive analysis, in order to adapt to the new environment, the design of which has been redesigned to

3、 improve the machine to clear the bunker after both meeting the processing requirements and the structure is simple, reasonable program. This paper introduced the structure of a variety of different forms of the role of coal bunker, coal bunker classification, a common accident blocking, analysis of

4、 the coal bunker to plug the cause of the accident and the mechanism of blocking. Coal bunker for congestion, based on the basis of preliminary studies on the coal bunker to the clearing device plugged in general, including the overall device to the clearing profile, the clearing device structure an

5、d working principle. The clearing device design is the major components for this design because its design quality is directly related to the coal bin to the clearing drive the success of the design including the coal bin to the clearing machine,some of the major components, including the growth of

6、devices, storage devices, buffer device, the angle adjustment device and bolt connections, such as design and more nuclear. Key words: coal bin to the clearing energy, the growth of devices, energy storage device, buffer device, the angle adjustment device - III - 目目 录录 前前 言言 1 1.煤仓堵塞的机理 2 1.1 煤仓的作用 . 2 1.2 煤仓的分类 . 2 1.3 常见的堵塞事故 4 1.4 堵塞事故发生的原因 . 7 1.4.1 粗颗粒状(或块状)为主的煤 8 1.4.2 细颗粒状(或粉状)为主的煤 10 2.煤仓疏通机疏通装置设计. 15 2.1 疏通装置的总体简介 . 15 2.2 疏通装置的结构 15 2.3 工作原理 16 3.疏通装置主要部件
