High Quality Port Bucket Wheel Excavator

Product Introduction:

Operational Principle
The bucket-wheel excavator operates in stationary mode during material excavation, relying on the coordinated motion of its front-mounted rotating bucket wheel and the boom’s slewing action to continuously shear and load materials into the buckets. As the buckets ascend to a predetermined elevation during rotation, gravitational discharge directs materials onto the intake conveyor belt. These materials are subsequently routed through a hopper to the discharge conveyor system for final transfer to trucks or bulk transport systems. Upon completing a material layer, the machine advances or retracts its boom to excavate subsequent layers vertically downward. Layer thickness is regulated by the excavator’s linear displacement or boom extension, while excavation width correlates with slewing velocity. Mobility serves a secondary role, with primary emphasis on continuous excavation via the bucket wheel and material transport through conveyor systems.

Structural Configuration
The bucket-wheel excavator comprises six core subsystems: tracked undercarriage, slewing assembly, excavation mechanism, material handling system, electrical propulsion system, and hydraulic control system. Distinctive features include:

(1) Tracked Undercarriage System
Contemporary bucket-wheel excavators predominantly utilize crawler-based mobility systems, with select models employing walking mechanisms. Dual-track configurations are standard for medium/small units, while large-scale excavators adopt multi-track designs (triple/quadruple-track) to minimize ground pressure distribution.

(2) 360° Slewing Assembly
Incorporating a rotating superstructure and azimuth drive components, this system accommodates powerplants, transmission gear, control interfaces, and the operator cab. A slewing ring bearing enables full circumferential rotation of the superstructure about the vertical axis.

(3) Excavation Mechanism

Consists of the bucket-wheel assembly, articulated boom, elevation adjustment system, and drive train. The bucket wheel—a circumferential array of evenly spaced digging buckets—is mounted at the boom’s distal end. The boom pivots at its base via the superstructure’s portal frame, with angular positioning achieved through wire rope winches or hydraulic actuators to optimize cutting plane alignment. Boom variants include fixed-length and telescoping designs. The bucket-wheel drive module (electric motor, torque-limiting coupling, and gear reducer) is offset-mounted at the boom’s forward section to enable rotational power transfer.

(4) Material Handling System
Comprises sequential components: intake conveyor, surge hopper, and discharge conveyor. Bridge-type excavators incorporate an intermediate transfer conveyor within the bridging structure for extended material routing.

(5) Electrical Propulsion System
Implements grid-powered variable frequency drive (VFD) systems for precision motor speed regulation.

(6) Hydraulic Control System
Predominantly utilizes hydraulic actuators for bucket-wheel boom elevation control and discharge conveyor positioning adjustments.
