Background

The bucket-wheel stacker-reclaimer is widely used in large and medium bulk cargo wharfs, mine storage yards and other places, and has a plurality of advantages. But there is the shortcoming that residual material is many in bucket-wheel stacker reclaimer material operation, promptly: after the material taking is finished, the material with the thickness of about 500mm remained on the yard cannot be taken away. The cantilever frame of the bucket-wheel stacker-reclaimer is very long, the ground of a storage yard is uneven, and when materials are taken, the risk of collision between the bucket-wheel mechanism and the ground is caused when the bucket-wheel mechanism is too close to the ground. The bucket wheel mechanism is a rigid body, the ground of a storage yard can be damaged when collision occurs, and side-turning accidents of the bucket wheel stacker-reclaimer can also occur in serious cases. Therefore, the material taking operation of the bucket-wheel stacker reclaimer can keep a certain safe distance from the ground by controlling the bucket-wheel mechanism, and the phenomenon of a large amount of residual materials on the ground is caused. And the residual materials are cleaned by matching a loader with a bucket-wheel stacker-reclaimer, so that the cleaning efficiency is low and the energy consumption is high.
