Rotary cultivator in the countrys 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, Chinas 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.Keyword： Farm Machinery Rotary cultivator全套资料带CAD图，QQ联系414951605或1304139763第一章 概述大田的耕作机械主要有铧式犁和旋耕机两种。传统的耕作方式是三年一深耕(犁耕)、一年一旋耕(浅耕)。旋耕机由于具有耕地和耙地的双重作用,在耕地机械中占有重要的地位。旋耕机是一种由动力驱动的土壤耕作机械，旋耕机的耕作部件为旋耕刀辊,是由多把旋耕刀在刀轴上按螺旋线排列而成。旋耕机于19世纪中叶问世,但直到本世纪20年代
