摘 要
我國對旋耕機的研制始于20世紀50年代末，初期主要研制與手扶拖拉機配套的旋耕機，后來研制出與中型輪式拖拉機配套的旋耕機；70年代初完成了與當時國產(chǎn)的各類拖拉機配套的系列旋耕機的設(shè)計，并使之得到了推廣應(yīng)用；到80年代，與手扶拖拉機配套的旋耕機由專用型發(fā)展到兼用型，由與手扶拖拉機配套發(fā)展到與輪式及履帶式拖拉機配套。旋耕機在我國的發(fā)展經(jīng)歷了單機研制、發(fā)展系列產(chǎn)品、新產(chǎn)品開發(fā)和換代3個階段，隨著新的種植、耕作農(nóng)藝的發(fā)展和推廣，在旋耕機基礎(chǔ)上還研制出了多種用途的聯(lián)合復(fù)式作業(yè)機。新系列旋耕機采用的新型旋耕刀，綜合了合理的速度參數(shù)、幅寬和復(fù)式作業(yè)功能，采用旋耕機基礎(chǔ)件組合式結(jié)構(gòu)，可組裝在多種機型上，滿足不同的用途與農(nóng)藝要求。目前我國旋耕機的使用范圍不斷擴大，整機及零部件生產(chǎn)企業(yè)有100余家，從南方水田到北方旱地以及牧場、荒地和果林等都廣泛使用旋耕機進行耕耘作業(yè)。

Abstract
My rotary cultivator of the 1950s and the 20th century began with the end of the initial development and the main walking tractor supporting rotary cultivator and subsequently developed with medium-wheeled tractor supporting rotary cultivator ;70 1990s was made in China with the completion of the various series of rotary cultivator tractors supporting the design, and has been promoting the application; To the 1980s, from the rotary cultivator and walking tractor supporting dedicated to the development of both type, and by supporting the development of the walking tractor with wheeled and tracked tractors matching. Rotary cultivator in the country's development has a single research and development series products, new product development and updating of three stages, with new cultivation, the development and promotion of farming techniques, rotary cultivator basis also developed a multi-purpose joint compound operations aircraft. A new series of rotary cultivator new rotary knife, a reasonable speed integrated parameters, and the breadth of operational functions, the introduction of rotary cultivator basis of modular structure, assembly in a variety of models, and techniques to meet the requirements of different uses. At present, China's expanding use of rotary cultivator, and whole sets of parts production enterprises with 100 more from the South to the North dryland and irrigated pasture, forest lands and fruit were widely used rotary cultivator to work operations.
