The invention discloses a loader-digger for a construction site. The loader-digger structurally comprises a bucket, a traction moving part, a hydraulic motor, a hydraulic bucket rod, a movable arm, acab, a vehicle body, an engine, wheels, a crawling ladder and a digging arm. Long bucket teeth at the left end and the right end of the bucket are used for performing contact excavation on an excavation face when the improved loader-digger is used for excavation, the contact area between the long bucket teeth and the excavation face of the construction site is reduced, pressure is increased, and the long bucket teeth are easily inserted into mudstone. After the long bucket teeth on the two sides are inserted into mudstone, the mudstone starts to loosen through vibration of the bucket, so thatshort bucket teeth are inserted continuously to complete excavation operation. When soil is transported, a connecting rod and an auxiliary rod are used for fixing two pressing pieces to the digging arm, a movable pressing block is matched with a locking disc to lock and fix the movable arm and the digging arm at the same time, the movable arm and the digging arm fix the bucket to a traction position to limit the same, and the bucket is prevented from sinking; and surrounding workers or articles are protected, and the construction safety is improved.
本发明公开了一种建筑工地用挖掘装载机，其结构包括铲斗、牵引活动件、液压马达、液压斗杆、动臂、驾驶室、车体、发动机、车轮、爬梯、挖掘臂，本发明改进后在挖掘时，用铲斗左右两端的长斗齿对挖掘面进行接触挖掘，用长斗齿与建筑工地挖掘面的接触面积减少，压强增加，容易插入泥岩中。当两侧的长斗齿插入泥岩后，通过铲斗的震动，泥岩开始松动，有利于短斗齿继续插入，完成挖掘作业。将土壤进行运输时，用连接杆和辅助杆将两块压紧件固定将挖掘臂上，活动压块配合锁紧盘将动臂和挖掘臂同一锁紧进行固定，使得动臂和挖掘臂将铲斗固定在牵拉的位置上，对其进行限位，防止铲斗出现下沉现象，对周围的工作人员或者物品造进行保护，提高施工安全性。
