[0002] An excavator, also known as excavating machinery, also known as a power shovel, is an earthmoving machinery that uses a bucket to excavate materials above or below the machine's surface and load them into transport vehicles or unload them onto a stockpile. The materials excavated by an excavator are mainly soil, coal, sediment, as well as pre-loosened soil and rock. From the development of construction machinery in recent years, the development of excavators has been relatively fast, and excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of an excavator are: operating weight (mass), engine power, and bucket capacity.

[0003] When the existing bulldozing blade of an excavator is in use, it does not have an adjustable function, the extension length of the bulldozing blade cannot be adjusted, the leveling operation range is limited, and the operation efficiency is low. Content of the Utility Model

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the present utility model provides an adjustable bulldozer blade for an excavator, which has the following beneficial effects:

[0016] For the adjustable bulldozer blade for the excavator, when the length of the bulldozer blade body needs to be extended, the drive motor is turned on. The drive motor drives the threaded rod in the fixed sleeve to rotate, and the rotation of the threaded rod drives the moving block, the moving block drives the mounting plate, and the mounting plate drives the rotating connecting rod. The rotating connecting rod obliquely pushes the side shovel, so that the side shovel slides at both ends of the bulldozer blade body, thereby completing the adjustment of the length, increasing the bulldozing area of the bulldozer blade body, and effectively improving the operation efficiency.
