履带自走式苜蓿切割压扁机设计与试验

为适应西部地区苜蓿收获的需要,研制了一台履带自走式苜蓿切割压扁机。为此,进行了整机结构设计和总体布置,完成了零部件的选型、设计,并进行了样机试制。该机采用静液压无级变速驱动桥,实现了无级调速,操控简便。试验结果表明:样机爬坡度可达30%以上,最高作业速度可达10km/h,接地比压29k Pa,能够较好地满足山地苜蓿切割压扁作业的需求。

Crawler Self-propelled Alfalfa Cutting and Flattening Machinary Design and Experimental Study

In order to meet the requirements of alfalfa harvest of the western region,the paper developed a crawler self-propelled alfalfa cutting and flattening machinery. The whole structure design,general layout,parts selection and design, and prototype trial-production have been completed. Hydro static transmission has been used to achieve the variable speed and easy manipulation. The results showed that the maximum climbable gradient is 30%, the highest working speed is 10km/h,the ground specific pressure is 29 kPa. The prototype can meet the requirements of alfalfa working in mountainous region.
