自一九七八年开始,我们进行了液压平地铲运机的研制工作,至一九七九年该机正式投入生产试验。通过反复试验改进,于八○年十月份进行了鉴定。该机主要适用于大面积旱田及水浇地的平整、铲运表土作业。该机属于牵引式平地机,与东方红—75拖拉机配套。采用液压操纵,作业质量可达到细平或精平指标。该机主要由梁架、铲体、行走装置和液压调整系统等四部分组成。(见图一) Since 1978, we have carried out the research and development work of hydraulic flat-blade scrapers and formally put into production test by 1979. Through trial and error improvement, it was appraised in October of 1980. The machine is mainly suitable for large areas of dry land and irrigated land formation, scraping topsoil operations. The machine belongs to the traction grader, and the East Red -75 tractor supporting. Using hydraulic control, the quality of work can be achieved fine or fine indicators. The aircraft mainly by the beam frame, shovel, walking equipment and hydraulic adjustment system composed of four parts. (See figure I)
