[0002] Many large-scale mechanical equipment are generally used in construction, among which the most common is the excavator, and the bucket of the excavator is an indispensable and important component. When the excavator is in construction, it is generally used in conjunction with the bucket. In order to improve the wear resistance of the existing bucket, the existing bucket bottom wear-resistant plate structure adopts a whole rectangular wear-resistant plate, and the wear-resistant plate and the arc plate are corner-welded. This type of wear-resistant plate can basically ensure the rigidity and wear resistance of the bucket.

[0003] In order to improve the earth-breaking effect, the existing excavator bucket has multiple bucket teeth installed at the front end of the bucket for breaking the ground during use. Long-term use can easily cause a lot of wear on the front end of the bucket teeth, making the front end of the bucket teeth an arc structure, thereby reducing the earth-breaking effect and service life. Summary of the invention

[0007] Preferably, the connecting assembly includes a connecting plate symmetrically mounted on the top of the bucket, and the connecting plate is symmetrically provided with connecting holes.

[0008] Preferably, the wear-resistant assembly includes side wear plates symmetrically fixed to the side surfaces of the bucket, a bottom wear plate is arranged between two groups of the side wear plates, and the bottom wear plate is fixed to the bottom end of the bucket.

[0009] Preferably, a mounting hole for mounting the gear seat is provided on the bucket, and the gear seat is connected to the bucket via fixing bolts.

[0010] Preferably, a through hole for connecting a bucket tooth is provided on the tooth seat, and the bucket tooth is connected to the tooth seat by mounting bolts.

[0011] Preferably, there are multiple groups of bottom grinding plates, and the multiple groups of bottom grinding plates all match the curvature of the bottom end of the bucket.

[0012] Preferably, the bucket tooth is in an inclined structure on a side away from the bucket, and the protection component has the same inclination angle as the bucket tooth.

[0013] The beneficial technical effects are:

[0014] By setting up a protective component, during the use of the bucket, the breaking plate in the protective component will first contact the material to break the soil. At this time, the breaking plate is subjected to force to drive the sliding block to move along the slide groove and stretch the reset spring until one end of the breaking plate moves above the bucket tooth. The bucket tooth then breaks the soil again, thereby reducing the pressure and wear on the bucket tooth, improving the breaking effect and service life, and after use, the reaction force of the reset spring resets the breaking plate for subsequent operations.
