推土板(推土铲)是推土机的主要作业装置,发动机输出功率的40%消耗于推土板的作业过程,开发新型推土板,是推土机节能降耗的主要措施。本文根据国、内外资料,对新型推土板的开发现状作一综述,供同行参考。1.推土板的工况分析推土板的功能是掘削(切削)土 Bulldozer (bulldozer) is the main operating device of bulldozer, 40% of the engine output power is consumed in the operation of bulldozing plate, the development of new bulldozing plate, bulldozer is the main energy saving measures. Based on the domestic and foreign information, this paper reviews the current status of the development of the new bulldozing plate for peer reference. 1. Bulldozer condition Bulldozing plate is the role of mining (cutting) soil
