[0002] Excavating machinery is one of the main types of construction machinery. As an important part of the working device of an excavator, the quality of the bucket structure will directly affect the working quality and efficiency of the entire excavator.

[0003] Currently, the commonly used bucket includes a bucket bottom plate and side plates located on both sides of the bucket bottom plate. During the excavation process, the bucket bottom plate and the side plates are in direct contact with the materials and are often subjected to the collision and friction of the materials, which easily causes deformation and cracking. The existing buckets usually set reinforcing plates at the edges of the bucket bottom plate and the side plates to increase the overall strength of the bucket structure. However, the surfaces of the bucket bottom plate and the side plates are not protected, and it is easy to wear during long-term use, resulting in a decrease in the structural strength and a reduction in the service life of the bucket. Summary of the Utility Model

[0023] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0024] A typical implementation manner of the present utility model is as Figure 1As shown in the figure, an excavator bucket structure includes a bucket bottom plate 1 and side plates 2. The longitudinal section of the bucket bottom plate 1 is U-shaped. There are two side plates 2, which are symmetrically arranged on both sides of the bucket bottom plate 1. The bottom edge of the side plate 2 is arc-shaped and is adapted to the bucket bottom plate 1, so that the side plates 2 are welded to both sides of the bucket bottom plate 1.

[0025] A side cutting edge plate 3 is arranged above the side plate 2. The side cutting edge plate 3 is fixedly welded to the side plate 2. The width of the side cutting edge plate 3 is greater than the width of the side plate 2, so as to protect the side plate 2. A front cutting edge plate 4 is arranged at the front end of the bucket bottom plate 1. Both ends of the front cutting edge plate 4 are respectively fixedly welded to the side cutting edge plate 3. A plurality of tooth seats 5 are arranged on the front cutting edge plate 4. The plurality of tooth seats 5 are evenly distributed on the side of the front cutting edge plate 4 away from the bucket bottom plate 1. A bucket tooth 6 is detachably connected to the tooth seat 5. When the bucket tooth 6 is worn, it can be removed from the tooth seat 5 for replacement.

[0026] On the outer surface of the rear end of the bucket bottom plate 1, ear plates 7 are symmetrically arranged. A shaft hole 8 is opened on the ear plate 7. Through the ear plate 7, it can be connected to the excavator bucket rod, so as to drive the bucket to move by using the excavator bucket rod.

[0027] As Figure 2 shown, a number of bucket bottom reinforcement plates 9 are arranged on the inner surface of the bucket bottom plate 1. The number of bucket bottom reinforcement plates 9 extends from the rear end of the inner surface of the bucket bottom plate 1 to the front end of the inner surface of the bucket bottom plate 1. And the longitudinal section of the bucket bottom reinforcement plate 9 is U-shaped and is adapted to the bucket bottom plate 1. The number of bucket bottom reinforcement plates 9 covers the inner surface of the bucket bottom plate 1, and there is a set distance between adjacent two bucket bottom reinforcement plates 9. By arranging a number of bucket bottom reinforcement plates 9 on the inner surface of the bucket bottom plate 1, while improving the strength of the bucket bottom plate 1, the wear resistance of the bucket bottom plate 1 is improved.

[0028] On the side of the front cutting edge plate 4 away from the tooth seat 5, a number of wear-resistant plates 10 are arranged. The number of wear-resistant plates 10 is located between the bucket bottom reinforcement plate 9 and the tooth seat 5, and the number of wear-resistant plates 10 is arranged corresponding to the number of bucket bottom reinforcement plates 9. By arranging the wear-resistant plates 10, the wear resistance between the bucket bottom reinforcement plate 9 and the tooth seat 5 is improved.

[0029] As Figure 3 shown, a side reinforcement plate is arranged on the outer surface of the side plate 2. The side reinforcement plate includes a lower reinforcement plate 11 and an upper reinforcement plate 12. Among them, the lower reinforcement plate 11 is located at the lower part of the outer surface of the side plate 2 and is used to improve the structural strength of the lower part of the side plate 2. There are a number of upper reinforcement plates 12. The number of upper reinforcement plates 12 is arranged between the side cutting edge plate 3 and the lower reinforcement plate 11. The number of upper reinforcement plates 12 is arranged at intervals on the outer surface of the side plate 2 in turn.

[0030] There is a set distance between the lower ends of the number of upper reinforcement plates 12 and the lower reinforcement plate 11, and there is a set distance between the upper ends of the number of upper reinforcement plates 12 and the side cutting edge plate 3.

[0031] By arranging an upper reinforcing plate 11 and a lower reinforcing plate 12 on the outer surface of the side plate 2, the structural strength of the side plate 2 is improved, the phenomenon that the side plate 2 is deformed and cracked due to collision is avoided, and the service life of the bucket is prolonged.
