1.改进目的小型挖掘机应用越来越广泛,是当下销量最大的工程机械产品之一。小型挖掘机均配有推土铲,其主要作用是推土、平地,在挖掘作业时还可起辅助支撑、调平作用,以增加挖掘机作业时的稳定性。普通推土铲采用简单的整体式结构,如图1所示。因考虑挖掘机行走通过性要求,普通推土铲宽度不能超过挖掘机机身宽度。由于普通推土宽度较窄,推土效率不高,为此需要对推土铲进
1. Improvements The use of small excavators is becoming more and more widely used. It is one of the largest sales of construction machinery products. The small excavators are all equipped with a dozer shovel. The main role of the shovel is to push soil and flat ground. It can also play an auxiliary support and leveling function during the excavation work to increase the stability of the excavator. Ordinary bulldozers use a simple, integral structure, as shown in Figure 1. Due to the consideration of the walkability requirements of the excavator, the width of the ordinary blade cannot exceed the width of the excavator body. Due to the narrow width of ordinary bulldozing, the efficiency of earth-moving is not high. Therefore, it is necessary to push the earth into the earth.
