Description

Technical Field

[0001] This utility model relates to the field of roller screening bucket technology, and in particular to an electric screening bucket. Background Technology

[0002] Because existing municipal roller screening buckets need to be mounted on construction machinery, and construction machinery generally has a hydraulic power system, the rollers corresponding to the roller screening buckets are generally driven by hydraulic motors in order to directly utilize the hydraulic power of the construction machinery.

[0003] Due to the rapid development of new energy vehicles, some existing engineering vehicles have also adopted new energy power systems. However, since the existing screening buckets are driven by hydraulic motors, when new energy engineering vehicles use existing screening buckets, the electric system needs to be converted into hydraulic power before the screening buckets can be driven to work. This will greatly increase power loss and reduce working range, leaving room for further improvement. Utility Model Content

[0010] According to the electric screening bucket, two sprockets of the same specification are fixedly sleeved on the outer side of each of the three double sprocket bushings, and the two sprockets of the same specification are respectively set at the inner and outer ends of the double sprocket bushing.
