What is a shovel excavator?
The shovel excavator is a common engineering machinery equipment that is widely used in earth excavation operations in mining, construction, water conservancy and other fields. Its characteristic is that the bucket digs upward, which is suitable for digging materials higher than the stopping surface. This article will introduce in detail the working principle, structural characteristics, application scenarios and recent hot topics of the shovel excavator.
1. Working principle of front shovel excavator
The front shovel excavator drives the bucket upward through the hydraulic system. The main work processes include:
1.excavation stage: The bucket digs upward from the bottom and is lifted after being filled with materials.
2.turning phase: The bucket rotates to the unloading position.
3.Unloading phase: The bucket opens and the material is discharged.
4.reset phase: The bucket returns to the excavation position and prepares for the next operation.
2. Structural characteristics of front shovel excavator
The front shovel excavator mainly consists of the following components:
| Part name | Function description |
|---|---|
| Bucket | For digging and loading materials |
| Boom | Support the bucket and control its lifting |
| stick | Connect the bucket and boom to adjust the digging depth |
| Hydraulic system | Provide power and control the movement of various components |
| Rotary platform | Achieve 360° rotation of the fuselage |
| Tracks/Tires | Support the body and enable movement |
3. Application scenarios of front shovel excavators
Front shovel excavators are suitable for the following operating scenarios:
| Application areas | Specific use |
|---|---|
| Mining | Loading of ore, coal and other materials |
| construction project | Foundation pit excavation and earth moving |
| water conservancy project | River dredging and dam construction |
| ROAD WORK | Roadbed filling and stone loading |
4. Recent hot topics and hot content
