Description

Technical Field

[0001] The utility model relates to the field of construction equipment accessories, in particular to a slag cleaning device for a bucket. Background Art

[0002] Buckets and grabs are important accessories on excavators and are a kind of bucket-shaped components that directly contact the soil. The oil cylinder uses high-pressure oil as the medium and the connecting rod as an auxiliary mechanism to drive the bucket for excavation work.

[0003] When used to excavate substances with strong adhesiveness such as soil and silt, the bucket wall of the bucket is prone to adhesion. If not cleaned for a long time, the soil adhered in the bucket will accumulate more and more, which will affect the excavation efficiency and normal construction use. To ensure the normal use of the excavator, the bucket needs to be cleaned. The conventional cleaning method is to suspend the work of the excavator and manually clean the soil in the bucket with the help of tools. This method has low cleaning efficiency, affects the construction progress, and is only applicable to the conventional working environment. When the excavator is in complex terrain environments such as deep pits and highlands, manual cleaning is inconvenient and there are certain safety risks. This is the existing problem. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a slag cleaning device for a bucket, which automatically clears soil and slag while the bucket is discharging materials, without manual cleaning and without applying additional power to improve the existing problems.
