Classification and structure analysis of excavator

In the excavator according to the driving mode, according to different walking mode, according to different transmission mode, according to the classification of use, the structure of the excavator and the common structure of the relevant knowledge mining.

Excavator structure

analysis: excavator is composed of bucket, bucket column, rotary arm, foot or support wheel and hydraulic system. The barrel and barrel are hinged with the column, which is hinged at the end of the rotating arm. The hydraulic system controls the lifting of the rotary arm and the rotation in the horizontal plane through various special cylinders, and the barrel rod rotates in the vertical plane, lifts the leg, digs, lifts and tilts the barrel, etc., so that the bucket can dig earth at 3 to 4 meters above and below the ground, and unload the soil to the designated part. The bucket capacity of the excavator is about 15 kilowatts according to the size of the tractor power, and each unit has 0.1 cubic meters. After unloading, it is also equipped with a variety of working parts and multiple operations such as bucket, multi-tooth partial crawling or lifting hooks for material loading and lifting.

Let's introduce the classification of excavators:

1, the common excavator according to the drive mode has two kinds of internal combustion engine driven excavator and electric driven excavator. Electric excavators are mainly used in flammable and explosive places such as high altitude hypoxia and underground mines.

2, according to different walking methods, excavators can be divided into crawler excavators and wheeled excavators.

3, according to the use of points, excavators can be divided into general excavator, mining excavator, Marine excavator, special excavator and other different categories.

4, according to different transmission methods, the excavator is divided into hydraulic excavator and mechanical excavator. Mechanical excavators are mainly used in large mines.
