常规结构的铲运机对于铲斗的入土控制性能、保养方便性、视野和工艺性等方面均有很多不如人意的地方。如辕架形状复杂，制造成本高；提升液压缸伸缩时，使机架产生横向位移，致使铲运机通过性差等等。 在解决这些问题之前，我们不妨先分析一下特定工况对铲运机的一些要求。铲运
The conventional structure of the scraper for the bucket into the soil control performance, ease of maintenance, vision and craftsmanship and so there are many unsatisfactory places. If the frame shape complex, high manufacturing costs; enhance the hydraulic cylinder telescopic, the rack has a lateral displacement, resulting in poor through the scraper and so on. Before solving these problems, we may wish to analyze some of the specific conditions of the scraper on some of the requirements. Scrapping
