Bucket wheel stacker reclaimer adopts bucket wheel continuous reclaimer, which piles materials together with belt conveyor and is a rail loading and unloading machine. It is a special machinery for bulk materials storage yard, evolved from bucket wheel excavator, and forms a mechanized transportation system for storage yard with unloading (hand) machinery, belt conveyor and loading (automobile) unit, with a capacity of more than 7,000 tons per hour. The operation of bucket wheel stacker-reclaimer has strong regularity and is easy to be automated. There are manual, semi-automatic and automatic controls. ..

The structure of bucket wheel stacker reclaimer consists of cantilever type and bridge type. This paper is about boom type.

Cantilever bucket wheel stacker-reclaimer has two methods: stacking and taking. The materials stacked by the belt conveyor are transported from bulk materials to the disposal vehicle, to the end of the boom of the belt conveyor, and the boom is thrown from the frontcourt to the disposal site. Through the operation of the computer, the boom is rotated, and it is expected that the stack will be neatly formed into a trapezoidal cross-sectional shape by pitching. The reclaimer is continuously realized by the rotation of the boom and bucket wheel. The material unloaded by the unloading plate is processed to the cantilever belt conveyor running in the reverse direction, and then the machine unloads the material to the belt conveyor in the hopper yard at the lower center. Through the operation of the computer, the rotary arm, the pitching wheel and the bucket wheel can pile up the reserve materials.

Cantilever bucket wheel stacker-reclaimer consists of bucket wheel, slewing mechanism, belt conveyor, tail car, pitching mechanism and walking mechanism.
