摘要
刮板输送机是综采工作面配套设备的重要组成部分,是煤炭装运的第一个环节。因此，刮板输送机的输送能力在很大程度上决定了采煤工作面的生产能力和效率。然而，我国生产技术落后，目前设计生产的刮板输送机装机功率小,输送能力低,运输距离短，耐久性差,可靠性低，寿命短。综合分析我国刮板输送机的使用现状，设计制造高性能的刮板输送机迫在眉睫。本文首先综合比较了各种类型输送机的特点，根据实际情况选用了中单链型刮板输送机。而后，对中单链型刮板输送机进行了总体结构设计。对机头传动装置、过渡槽、中部槽、刮板链、刮板、链轮、机尾等主要部件进行了技术分析和结构设计，完成了中单链型刮板输送机的整体设计。此次设计的中单链型刮板输送机左右两侧对称，可以在两侧壁上安装减速器，以适应左、右采煤工作面的需要。另外，可以很容易将机尾改装成机头，而适应各种特殊情况。此次设计的中单链型刮板输送机的特点是结构简单,受力均匀,运行平稳,摩擦阻力小,溜槽利用率高，弯曲性能好,不易出现堵塞，具有很强的适应性。

Abstract
The scraper conveyer is the synthesis picking work surface important constituent of the supplementary equipment. It is the first link of the coal shipping. Therefore, the scraper conveyer delivery capacity has decided the mining coal working surface productivity and the efficiency in a great degree; however, our country was lagged behind at present; the scraper conveyer installing equipment power is small. The delivery capacity is low; the transportation is away from short, the durability is bad; Reliability is low; and the life is short. The generalized analysis our country scraper conveyer use present situation, the design manufacture high performance scraper conveyer is imminent. This article first synthesized has compared each kind of type conveyer characteristic, has selected center simple chain according to the actual situation the scraper conveyer. But after, the scraper conveyer has carried on the overall structural design to center simple chain. To the nose transmission device, the aqueduct, the middle trough, the scraper chain, the scraper, the chain wheel, the airplane tail and other major component has carried on the technical analysis and the structural design, has completed center simple chain the scraper conveyer overall design.  This design center simple chain about the scraper conveyer two sides are symmetrical, may install the reduction gear on two sidewalls, by left meets, the right mining coal working surface need. Moreover, it may very easily reequip the airplane tail the nose, but adapts each kind of peculiar circumstance. This design of center simple chain of the scraper conveyer characteristic includes: the structure is simple, the stress is even, moves steadily, the friction drag is small, the chute use factor high, the curving performance is good, It is not easy to appear stops up, has the very strong compatibility.
Key Words: Scraper Conveyer; Middle Trough; Round Link Chain

引言
80年代中后期，发达国家纷纷推出全新的高产高效输送机,其特点为大功率、大运量、长运距、高可靠性、长寿命。而我国生产技术落后，目前设计生产的刮板输送机装机功率小,输送能力低,运输距离短，耐久性差,可靠性低，寿命短，我国目前的刮板输送机的技术水平只相当于80年代初期的国际水平,落后于国际先进水平10～15年，目前尚没有自己的高产高效输送机，高产高效工作面的配套设备还只能依靠进口。而刮板输送机是综采工作面配套设备的重要组成部分,是煤炭装运的第一个环节,在很大程度上决定了采煤工作面的生产能力和效率，因此，研究制造自己的高产高效输送机迫在眉睫。作为新时代的大学生，是祖国的未来，理应为祖国的繁荣昌盛做出自己应有的贡献，结合中国的刮板输送机现状，我设计了中单链型刮板输送机，本文首先综合比较了各种类型输送机的特点，根据实际情况选用了中单链型刮板输送机。而后，经过半年的思考钻研对中单链型刮板输送机进行了总体结构设计。对机头传动装置、过渡槽、中部槽、刮板链、刮板、链轮、机尾等主要部件进行了技术分析和结构设计，完成了中单链型刮板输送机的整体设计。此次设计的中单链型刮板输送机的特点是结构简单,受力均匀,运行平稳,摩擦阻力小,溜槽利用率高，弯曲性能好,不易出现堵塞，具有很强的适应性。
