Description

technical field

[0001] The invention mainly relates to the technical field of excavators, in particular to a width-adjustable bucket for an excavator. Background technique

[0002] As the king of construction machinery, the excavator is widely used in various occasions, and it has the functions of digging and shoveling. The bucket of the excavator determines the performance and application range of the excavator. It usually consists of two side plates and a bucket plate between the side plates. Since the distance between the two side plates is fixed, the bucket has a constant width. However, due to different excavation conditions, buckets of different widths are required, which requires replacement of buckets of appropriate width, thereby increasing cost and labor intensity. Therefore, it is necessary to design a width-adjustable bucket with important application value. There is also an improvement to the bucket in the prior art, so that its width can be adjusted, but the...
