摘      要
 隨著科學(xué)技術(shù)的不斷發(fā)展，農(nóng)業(yè)機械化技術(shù)也發(fā)展到了一個新的水平；隨著農(nóng)業(yè)機械化技術(shù)的發(fā)展，的甘蔗收割機的發(fā)明成為目前各界人士關(guān)心的熱點問題。
 本文介紹了甘蔗收割機的研究背景、甘蔗收獲機械的研究現(xiàn)狀，分析了甘蔗收獲機械的發(fā)展對策及前景，敘述了雙排甘蔗收割機的實現(xiàn)原理和工作過程，詳細講述了雙排甘蔗收割機中提升裝置、轉(zhuǎn)向裝置以及支撐裝置的設(shè)計過程。這次和同組人員一起設(shè)計的的切段式甘蔗收割機能夠更獨特地更好地適應(yīng)各種狀態(tài)下的熱帶甘蔗的收割，包括倒伏和半倒伏的甘蔗。而且，該收割機在田間作相對自由運動時，不損壞甘蔗桿，也不會將甘蔗拔起。這種雙排甘蔗收割機不會提前收割鄰排的甘蔗，而且在田間自由運動時不會被甘蔗阻塞入口。其中本人設(shè)計的提升裝置是用來提升和橫向向上分離倒伏的甘蔗，并且用來支撐起倒伏的甘蔗大量的向中心線運動即收割機向著支撐起的甘蔗條往前走。轉(zhuǎn)向裝置用于使支撐起的甘蔗桿向中心線橫向移動并且在切頂之后，甘蔗進入收割機之前對著收割機的運動方向推進甘蔗。
 總之，用機械收割甘蔗已經(jīng)取得更多更廣泛應(yīng)用，也將代替人工收割。我也期待著能夠在市場上早日看見象我們所設(shè)計的這種集專業(yè)化、智能化，自動化、敏捷化，高效化、小型化、簡單化、環(huán)保化為一體的甘蔗收割機。

Abstract
 Along with the constant developing of science and technology, the world’s outfit industry level has got great advance. And along with it, the course of industrialization has been greatly pushed, and so does the  technology of farming mechanization. As a result, an invention of special cane harvester with brainpower, which is smart, has high efficiency, can realize simplification and automatization and protect the environment has become the focus of people of all classes.
 This paper introduces the research backgrounds and present situation of cane harvester and analyzes the development countermeasure in the future. Then it expatiates two-row harvester’s working theorem and procedure in detail. Besides that, the design of lifting, scroll and support mechanism are also the key parts. The chopper-type harvester of the present invention is particularly well suited for harvesting cane which includes semi-erect and lodged cane stalks common to high yield varieties of tropical sugar cane. The harvester includes a front end which allows for relatively free movement of the harvester through the field without damaging cane stalks or polling the roots of the cane out of the ground. The two-row harvester does not require cutting through each adjacent row of the cane prior to harvesting, and allows free movement of the harvester through the field without choking the intake of the cane int
 The gatherer mechanism which I have designed for lifting and transversely separating fallen cane stalks upwardly and for supporting the fallen cane stalks along substantially a gatherer centerline as the harvester moves toward the supported cane stalks. And a turnaround device for moving the supported cane stalks transvers
 ely from the gatherer centerline and for thrusting the cane stalks in the direction away from forward movement of the harvester after topping the cane
 
 stalks and prior to receiving the cane stalks into the harvester. 
 In a word, harvesting cane with machine has become more and more popular, and it will replace man force in the end. I also look forward to putting this very kind of cane harvester we designed into market as soon as possible.
 Key words: Cane harvester； Scroll support and lift mechanism；
