侧边传动式旋耕机的设计

摘要：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，在各种土壤条件下一次性可达到待播状态，可基本满足农业精细耕作的要求。近年来，我国进行了种植

业结构调整，特别是北方地区，耕整用宽幅高速型旋耕机成为发展方向，大中型拖拉机具有强劲的动力输出、

较大的牵引力和悬挂提升能力，为配套旱地耕作型联合作业提供了先决条件。而旋耕作为驱动型耕作机械，易

于更换和附加工作部件，形成灭茬、深松、碎土、做畦、起垄、开沟、精量半精量播种、深施化肥、铺膜、镇

压和喷药等多项作业的结构紧凑的联合作业机组，大幅度提高了生产效率，降低了作业成本。本次设计的侧边

传动式旋耕机结构简单、生产率高、功率消耗少、经济效率高。

Design of Side Transmission TypeRototiller

Abstract: Rotary cultivator is a kind of soil preparation machine with strong practicability and

wide application. 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.
