Technical Field

[0001] The invention relates to the field of earthwork and engineering machinery, and in particular to an adjustable excavator bucket. Background Art

[0002] In modern earthwork projects, excavators are the main earthmoving machinery and are widely used in various construction sites. Traditional excavator buckets are generally designed with a fixed width, and buckets of different sizes need to be replaced according to different operation requirements. This approach has the following problems:

[0003] Low operating efficiency: Replacing the bucket takes a lot of time and often requires manual assistance, which increases construction downtime and reduces overall operating efficiency.

[0004] Increased costs: Construction companies often need to purchase buckets of various sizes to meet different operational requirements, which increases equipment investment and operating costs. In addition, the labor costs incurred during bucket replacement cannot be ignored.

[0005] Poor applicability: In complex construction environments, soil properties, excavation depths and operation types often change, making it impossible for a fixed-width bucket to meet the flexible needs of construction, thus hindering project progress.

[0006] Complex operation: Excavator operators need to be familiar with the use and replacement procedures of different buckets, which increases the complexity of operation and the risk of errors for novice or inexperienced operators.

[0007] Therefore, there is an urgent need for an excavator bucket that can quickly adjust the width of its bucket mouth according to different operating requirements without replacing the bucket body. Such a design can not only improve the flexibility of construction, but also reduce the demand for human resources and capital investment. Summary of the invention
