Mechanical Action Classification Of Excavator Bucket

According to their different mechanical actions, they are divided into front shovel, backhoe, grab bucket, and dragline.
The front shovel of the excavator is hinged at the end of the boom and driven by an oil cylinder. During operation, the excavation force is from bottom to top, and the excavation trajectory often follows an arc. It is suitable for excavating sand, gravel, coal mines, and other operations above the stopping surface.
Excavator Backhoe: Articulated with the arm connecting rod, driven by an oil cylinder, the excavation force is from top to bottom during operation, and the excavation trajectory is a circular arc. It is suitable for excavating soil layers, sand and gravel, coal mines and other construction operations below the stopping surface.
The excavator's grab bucket is shaped like a shell, and it uses a hydraulic cylinder to drive the opening and closing of the grab bucket like a shell to grab materials, or a rope roll is used to vertically cut into the material and mechanically grab it according to its own weight; It is generally used for excavation of building foundation pits, deep excavations, and loading of loose materials such as coal, sand, clay, gravel, etc. It is particularly suitable for excavation or loading on one side of ditches or restricted spaces.
The excavator is shaped like a dustpan and has a toothed seat plate and bucket teeth. During homework, the bucket is thrown onto the excavation surface, and the shovel teeth use their own weight to cut into the soil layer. Then, the bucket is pulled by a cable to excavate, and when it is full, the bucket is lifted by a lifting cable. The unloading point is adjusted by turning the steering platform, and the bucket is flipped to unload the soil. The soil below the machine surface can be excavated, but the excavation accuracy is poor.
