[0014] According to one embodiment of the present invention, the inner wall of the fixed circular tube is stepped, and the inner wall diameter at the end of the fixed circular tube is larger than the inner wall diameter inside the fixed circular tube.

[0015] The advantages and beneficial effects of this utility model are as follows: The reinforced excavator bucket support of this utility model has a reasonable structure. By setting a reinforced round tube assembly, the connecting block at the end of the fixed round tube is fixedly connected to the bucket support body, increasing the connection area between the fixed round tube and the bucket support body, thereby enhancing the connection strength between the fixed round tube and the bucket support body, improving the durability of the fixed round tube, and reducing the occurrence of safety hazards.

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0023] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0024] like Figure 1-4 As shown, the reinforced excavator bucket head support of the embodiment includes a bucket head support body 1. The lower end of the bucket head support body 1 is provided with an installation groove 11. There are two symmetrically arranged installation grooves 11, which are respectively located on both sides of the bucket head support body 1. It also includes a reinforcing round tube assembly. The reinforcing round tube assembly includes a fixed round tube 2 and connecting blocks 3 respectively located at both ends of the fixed round tube 2. The connecting blocks 3 are fixedly connected to the reinforcing round tube and fixedly connected to the end face of the bucket head support body 1.

[0025] With this design, the connecting block 3 at the end of the fixed round tube 2 is fixedly connected to the bucket head support body 1, which increases the connection area between the fixed round tube 2 and the bucket head support body 1, thereby increasing the connection strength between the fixed round tube 2 and the bucket head support body 1, and thus improving the durability of the fixed round tube.

[0026] Furthermore, reinforcing rings 4 are also provided at both ends of the axial sidewall of the fixed circular tube 2, and the reinforcing rings 4 are fixedly connected to the fixed circular tube 2.

[0027] This design increases the thickness of the end of the fixed round tube 2, thereby enhancing its strength and further improving its quality and service life.

[0028] Furthermore, a wear-resistant sleeve 5 is fixedly provided at the inner end of the fixed circular tube 2.

[0029] This design avoids the premature wear of the inner wall of the fixed circular tube 2 due to the rotation of the excavator bucket.

[0030] Furthermore, the width of the connecting block 3 is consistent with the width of the bucket head support body 1.

[0031] This design maximizes the connection area between the connecting block 3 and the bucket head support body 1, thereby improving the connection strength.

[0032] Furthermore, the outer end face of the connecting block 3 is provided with a weight-reducing inclined surface 31.

[0033] This design reduces the weight of the connecting block 3, thereby reducing the stress on the bucket head support body 1.

[0034] Furthermore, the reinforcing ring 4 is provided with an arc-shaped chamfer 41.

[0035] Furthermore, the connecting block 3 is welded to the bucket head support body 1.

[0036] This design achieves the goal of firmly fixing the connecting block 3 to the bucket head support body 1.

[0037] Furthermore, the fixed circular tube 2 is fixedly connected to the mounting groove 11.

[0038] This design achieves the goal of firmly fixing the fixed circular tube 2 to the bucket head support body 1.

[0039] In another specific embodiment, the inner wall of the fixed circular tube 2 is stepped, and the inner wall diameter at the end of the fixed circular tube 2 is larger than the inner wall diameter inside the fixed circular tube 2.

[0040] With this design, the diameter of the fixed circular tube 2 end is increased, thereby increasing the diameter of the matching rotating shaft and improving the strength of the fixed circular tube 2 end.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
