农业机械耐磨件发展及研究现状

Development and research status of wear resistant parts of agricultural machinery

目前,我国农业发展水平已有了明显提升,通过拖拉机、播种机、收割机、机动车辆等进行土地耕种,不再依赖人力、畜力来完成。同时,还出现了越来越多的农业机械耐磨件,如:开沟机、旋耕机、水田耙、镇压器、铲刀、旋耕刀等。本文主要分析了农业机械耐磨件的工作条件、需求潜力、功能及机理,介绍了国内外农业机械耐磨件的常用材料、使用方法和使用寿命,并对提高农业机械耐磨件的使用寿命提出了合理性的建议,以供参考。

At present,China’s agricultural development level has been significantly improved,through tractors,seeders,harvesters,motor vehicles and other land tillage,no longer rely on human and animal power to complete.At the same time,there are more and more wear-resistant parts of agricultural machinery,such as ditching machine,rotary tiller,paddy harrow,compressor,spade knife,rotary tiller,etc.This paper mainly analyzes the working conditions,demand potential,function and mechanism of wear-resistant parts of agricultural machinery,introduces the common materials,usage methods and service life of wear-resistant parts of agricultural machinery at home and abroad,and puts forward reasonable suggestions for improving the service life of wear-resistant parts of agricultural machinery for reference.
