[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A kind of earthmoving excavator specially used for sticky soil layers, including a machine body, a bucket and an anti-sticking device, the bucket is fixedly connected to the machine, the anti-sticking device includes a driving member and a scraper, the driving member is arranged outside the bucket, the driving member is arranged on the side away from the bucket opening, the scraper is arranged inside the bucket, the driving member is used to drive the scraper to slide inside the bucket and clean the inner wall of the bucket; the scraper includes a push plate and a scraper, two scrapers are provided, the two scrapers are respectively arranged at both ends of the push plate, the scraper is hinged to the push plate, the push plate is provided with an elastic member, two elastic members are provided, one end of the two elastic members is fixedly connected to the push plate, and the other end is respectively fixedly connected to the two scrapers, the elastic member is arranged on the side of the push plate close to the driving member, and the elastic member is used to make the side of the scraper away from the push plate close to the inner wall of the bucket.

[0008] By adopting the above scheme, when it is necessary to clean the clay on the inner wall of the bucket, the driving member is first started to drive the scraper to move in the bucket. Since the diameter of the bucket gradually increases from the inside to the outside, the elastic member drives the scraper to rotate around the hinge under the elastic action of the elastic member, so that the side of the scraper away from the push plate is always close to the inner wall of the bucket, so that the scraper scrapes off the clay stuck on the inner wall of the bucket, thereby achieving the purpose of improving the working efficiency of earth excavation.
