Description

Technical Field

[0001] The utility model relates to the technical field of bucket wheels for excavators, in particular to a bucket wheel device for bucket wheel excavators. Background Art

[0002] Bucket wheel excavators are an innovative type of engineering machinery. They combine special traveling devices with the functions of an excavator, giving them better maneuverability and adaptability in complex terrain. Bucket wheel excavators are mainly composed of chassis, bucket, digging arm, and hydraulic system. The hydraulic system can achieve flexible control of the bucket and digging arm to complete various engineering tasks. The bucket capacity and digging depth of bucket wheel excavators can be adjusted according to work requirements to adapt to different engineering environments. However, existing bucket wheels for excavators have some shortcomings, such as:

[0003] Announcement No.: CN114320300B is a bucket wheel excavator suitable for mining sticky materials. This equipment ensures that the material on the lower belt conveyor can fall onto the belt conveyor of the discharge arm. The length of the lower belt conveyor should be set to the length of the upper belt conveyor. This effectively improves the stability of the bucket wheel excavator. However, in actual use, since this equipment is difficult to support the bucket wheel equipment, it may cause the bucket wheel mechanism to be difficult to adjust during actual use.
