Buckets Are Classified According To Mechanical Action

According to the different mechanical actions, it is divided into front shovel, backhoe, grab bucket and dragline.
The front shovel of the excavator is hinged at the end of the arm and is driven by an oil cylinder. During operation, the digging force is from bottom to top, and the digging trajectory is often in an arc. It is suitable for excavating sand, gravel, coal mines and other operations above the stop surface.
Excavator backhoe: It is hinged with the arm connecting rod and driven by the oil cylinder. During operation, the digging force is from top to bottom, and the digging trajectory is arc-lined. It is suitable for excavating the soil layer, sandstone, coal mine and other construction operations below the stop surface. .
The grab bucket of the excavator is shaped like a shell, and the hydraulic cylinder is used to drive the grab bucket to open and close like a shell to grab the material or the rope is wound vertically and cut into the material mechanically according to its own weight; it is generally used in the excavation of building foundation pits, deep pits, and coal and sand It is especially suitable for digging or loading on one side of a ditch or a restricted space.
The excavator dragline is in the shape of a dustpan, with a tooth seat plate and bucket teeth. Throw the bucket on the excavation surface during operation, the shovel teeth cut into the soil layer by their own weight, and then pull the bucket to excavate through the guide rope. Unload soil. The soil below the parking surface can be dug, but the digging accuracy is poor.
