[0003] The bucket of an existing excavator cannot arbitrarily expand or reduce its actual volume when in use. In some work scenarios, due to the fixed volume of the bucket, loading and unloading of materials may be inefficient. If the volume is too large, loading time and energy consumption may increase; if the volume is too small, loading and unloading operations may need to be performed more frequently.

[0012] Beneficial effects

[0013] 1. Compared with the existing technology, the bucket volume adjustable structure uses a push plate and an expansion chamber. Under the push of a hydraulic rod, the push plate can be positioned at any position in the expansion chamber, so that the size of the expansion chamber can be expanded or reduced at will, thereby controlling the volume of the bucket and allowing the operator to adjust the volume of the bucket according to specific work needs.
