Description

Technical Field

[0001] The utility model relates to the technical field of excavator buckets, in particular to an impact-resistant excavator bucket. Background Art

[0002] A bucket refers to the bucket installed on an excavator, also called a digging bucket. According to the working method, it is divided into a backhoe bucket and a front shovel bucket. The backhoe bucket is commonly used.

[0003] During the use of the existing impact-resistant excavator bucket, when the bucket is working, the bucket teeth on the bucket are always the first to contact the hard objects because the soil or other objects excavated by the excavator often contain extremely hard objects. The collision between the two can easily wear the bucket teeth. After long-term use, the bucket teeth may even break. In order to ensure the grabbing force of the bucket, the existing excavator bucket often has the front end bucket teeth and the bucket as an integrated structure. When the bucket teeth are damaged, the working efficiency and quality of the entire bucket will be affected, and the maintenance of the bucket teeth will be inconvenient, which will reduce the service life of the device.
