全电农用激光平地机的设计

针对现有农用激光平地机对复杂地形的适应能力差、精平机当作粗平机使用的问题,设计开发了全电农用激光平地机。全电农用激光平地机主要由机架、电动伺服缸、抬铲省力机构及斗门机构构成。其中,斗门机构主要由驱动系统、控制系统和机械部分组成,可以完成土壤的搬运。田间试验结果表明:在复杂地形下工作,该机构对土地平整的平整精度较传统机型有较大提高,作业质量符合农艺要求,机具结构设计合理。

Design of the Scraper Mechanism of All-electric Farm Laser Landscraper

Farmland grade is a kind of high speed, high precision and multi-purpose machinery,and is the key equip-ment infarmland improvement construction,it shows special advanced technology in farmland leveling.For the problem of the existing farm laser grader's poor adaptability to the complex terraing and using the fine-machine as coarse-machine, this article designed an all-electric farm laser landscraper.The existing laser landscraper's work efficiency for the first time in the field of complicated topography is low.The large amplitude in the work process usually makes the mast be eas-ily broken.The oil temperature in the hydraulic actuator will be too high while the landscraper working in a long time, and the hydraulic cylinder will appear an overshoot phenomenon.These phenomenons have a great influence on the grad-er leveling precision.The all-electric farm laser landscraper improved and innovated for the traditional landscraper.This has great significance for the improvement of the grader leveling precision.The all-electric farm laser landscraper is main-ly composed of frame, electric servo-cylinder, the laborsaving agency of lifting the shovel,the scraper mechanism.The scraper mechanism of laser landscraper is mainly composed of driving system, control system and mechanical parts.The scraper mechanism can be using to move the soi.Field experiment results showed that this agency can improve the level-ing precision compare with traditional models when it works in the complex terrains.The operation quality meet the need of the agronomic requirements.The agency is designed reasonable.
