摘要
刮板輸送機是綜采工作面配套設備的重要組成部分,是煤炭裝運的第一個環節。因此，刮板輸送機的輸送能力在很大程度上決定了采煤工作面的生產能力和效率。然而，我國生產技術落后，目前設計生產的刮板輸送機裝機功率小,輸送能力低,運輸距離短，耐久性差,可靠性低，壽命短。綜合分析我國刮板輸送機的使用現狀，設計制造高性能的刮板輸送機迫在眉睫。本文首先綜合比較了各種類型輸送機的特點，根據實際情況選用了中單鏈型刮板輸送機。而后，對中單鏈型刮板輸送機進行了總體結構設計。對機頭傳動裝置、過渡槽、中部槽、刮板鏈、刮板、鏈輪、機尾等主要部件進行了技術分析和結構設計，完成了中單鏈型刮板輸送機的整體設計。此次設計的中單鏈型刮板輸送機左右兩側對稱，可以在兩側壁上安裝減速器，以適應左、右采煤工作面的需要。另外，可以很容易將機尾改裝成機頭，而適應各種特殊情況。此次設計的中單鏈型刮板輸送機的特點是結構簡單,受力均勻,運行平穩,摩擦阻力小,溜槽利用率高，彎曲性能好,不易出現堵塞，具有很強的適應性。

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，發達國家紛紛推出全新的高產高效輸送機,其特點為大功率、大運量、長運距、高可靠性、長壽命。而我國生產技術落后，目前設計生產的刮板輸送機裝機功率小,輸送能力低,運輸距離短，耐久性差,可靠性低，壽命短，我國目前的刮板輸送機的技術水平只相當于80年代初期的國際水平,落后于國際先進水平10～15年，目前尚沒有自己的高產高效輸送機，高產高效工作面的配套設備還只能依靠進口。而刮板輸送機是綜采工作面配套設備的重要組成部分,是煤炭裝運的第一個環節,在很大程度上決定了采煤工作面的生產能力和效率，因此，研究制造自己的高產高效輸送機迫在眉睫。作為新時代的大學生，是祖國的未來，理應為祖國的繁榮昌盛做出自己應有的貢獻，結合中國的刮板輸送機現狀，我設計了中單鏈型刮板輸送機，本文首先綜合比較了各種類型輸送機的特點，根據實際情況選用了中單鏈型刮板輸送機。而后，經過半年的思考鉆研對中單鏈型刮板輸送機進行了總體結構設計。對機頭傳動裝置、過渡槽、中部槽、刮板鏈、刮板、鏈輪、機尾等主要部件進行了技術分析和結構設計，完成了中單鏈型刮板輸送機的整體設計。此次設計的中單鏈型刮板輸送機的特點是結構簡單,受力均勻,運行平穩,摩擦阻力小,溜槽利用率高，彎曲性能好,不易出現堵塞，具有很強的適應性。
