It cuts soil with good effect, breaks soil with powerful capacity and makes the soil surface flat after tillage, and so on. It can make soil in all kinds of conditions once achieved the state to be broadcast, which can basically meet the requirements of agricultural farming. In recent years, the planting structure of our country has been adjusted, especially in northern areas, thus tillage with a wide high-speed-type rotary tiller has developed. Medium-sized tractor provides a prerequisite for supporting dry land farming-based combination process with its strong power output, greater traction and enhanced ability of suspension. However, the rotary cultivator machine, as a driven model rotary machine, is easy to change, subjoins working parts and forms multiple-assignment and compact-structure joint operating units that clean stubble, loose the soil deeply, break soil, do beds, ridge, ditch, sow precise and quantity seeds, fertilize deeply, pave membrane, press soil and spray, which greatly improves the production efficiency and reduces the assignments cost. This designed side transmission type rotary cultivator in the paper has simple structure, high productivity, low power consumption and high economic efficiency. 朗读 显示对应的拉丁字符的拼音 字典 otary Cultivator；Rotary Blade；Gear-Box；Transmission System 1 前言 旋耕机是一种实用性强、应用范围广的耕整地机械，具有切土效果好、碎土能力强、耕后地表平坦等特点，15万台，与手扶拖拉机和小四轮拖拉机配套的旋耕机约200万台。旋耕机在南方水稻生产机械化应用中已占80％的比例，北方的水稻生产、蔬菜种植和旱地灭茬整地也广泛采用了旋耕机械。 （6）作业后，地膜与垄台要贴实、无皱折、无卷曲、无漏覆。 本次设计主要是要一次同步完成翻土、碎土、平整地表等作业，并且须通过合理选择参数和优化机构设计，使之整体尺寸、结构设计合理，功率消耗低，满足作业要求，同时克服其他可能存在的问题。 2 总体方案的选择及确定 随着农业科学技术的发展，旋耕机的研究和使用有很大的进展，出现了多种型式的产品。通过分析比较本次设计选用卧轴、悬挂式侧边传动的方案，这种结构对土壤适应强、混土效果好，能一次同步完成翻土
