0引言2012年,上海农场全面推广使用水田打浆埋草激光平地机,通过使用发现,由于农具加宽至7 m,作业时主机容易左右晃动出现平整横向落差较大的现象,从而在犁底层不是很平整的田块作业时(改制、耕地不平)只有降低车速、增大接幅宽度或增加作业遍数来实现整体平整效果。本项目在7 m水田平整机的基础上,安装水平自动控制系统,自动弥补田块犁底层不平整的缺陷,从而大幅提高作业功效,达到预期效果。1水田打浆灭茬激光平地机的改进和分析1.1水平自动控制系统原理上海农场试验所用水平自动液压控制系统的主要
0 Introduction In 2012, the Shanghai Farm fully promoted the use of paddy field burying laser grader. Through the use of the tool, it was found that due to the widening of the farm implements to 7 m, the mainframe was prone to swaying laterally to a large extent. As a result, the bottom of the plow was not Very flat field operations (restructuring, uneven arable land) only to reduce the speed, increase the width of access or increase the number of operations to achieve the overall smoothing effect. Based on the 7 m paddy leveling machine, this project installs the horizontal automatic control system to automatically compensate for the unevenness of the plow on the bottom of the paddy field so as to greatly improve the working efficiency and achieve the expected result. 1 paddy field stubble improvement and analysis of laser grader 1.1 level automatic control system principle Shanghai farm test level automatic hydraulic control system used mainly
