[0008] The present invention is further provided with reinforcing ribs on both sides of the connecting ear.

[0009] The present invention is further configured such that: an oil inlet is provided on the side of the shaft cylinder away from the welding plate, an oil nozzle is installed on the oil inlet by interference fit, through holes are provided on both sides of the bushing corresponding to the oil inlet, and an oil groove is provided in the bushing corresponding to the through hole.

[0010] The present invention is further configured such that: the bushings on both sides are provided with stepped grooves, and a sealing oil seal is detachably connected to the stepped grooves, and the sealing oil seal is interference fit with the bushing.

[0011] The present invention is further provided with a rubber liner on the inner wall of the shaft cylinder at the position where it fits the bottom of the shaft cylinder.

[0012] In summary, this utility model has the following beneficial effects: the connecting component set on the connecting ear can quickly connect the shaft and the connecting rod, saving time when changing the horse head and optimizing work efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and 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 on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] An easy-to-replace excavator part, such as Figures 1-3 As shown, it includes a shaft cylinder 1 and bushings 2 that are interference-fitted with both ends of the shaft cylinder 1. A welding plate 4 is provided on the outside of the shaft cylinder 1 and is attached to the wall of the shaft cylinder 1 for welding with the connecting rod. A quick-release assembly connected to the welding plate 4 is provided on the shaft cylinder 1.

[0019] Practical effect: The connecting component set on the connecting ear 3 can quickly connect the shaft cylinder 1 to the connecting rod, saving time when changing the horse head and optimizing work efficiency.

[0020] like Figures 1-3 As shown, specifically, the quick-release assembly includes several connecting ears 3 and hex socket screws 5. The connecting ears 3 are evenly distributed on the shaft sleeve 1 and clamp the welding plate 4. The hex socket screws 5 simultaneously fix the connecting ears 3 and the welding plate 4 through their threads. Reinforcing ribs 6 are provided on both sides of the connecting ears 3 to enhance the strength and stability of the connecting ears 3 and prevent deformation or damage during use.

[0021] Specific operation: Fit the bushing 2 and the welding plate 4 together, and clamp the welding plate 4 with the connecting lug 3 to prevent it from shaking. Connect the connecting lug 3 and the welding plate 4 by rotating the internal hex screw 5 to achieve quick disassembly and installation.

[0022] like Figures 1-3 As shown, an oil inlet 11 is provided on the side of the shaft cylinder 1 away from the welding plate 4. An oil nozzle 7 is installed on the oil inlet 11 by interference fit. The two bushings 2 are provided with through holes 21 corresponding to the oil inlet 11. An oil passage groove 22 is provided in the bushing 2 at the position corresponding to the through hole 21, so as to ensure that the lubricating oil can be evenly distributed between the shaft cylinder 1 and the bushing 2, thereby reducing friction and wear.

[0023] like Figures 1-3 As shown, the two bushings 2 are provided with stepped grooves 23. A sealing oil seal 8 is detachably connected to the stepped groove 23. The sealing oil seal 8 is interference-fitted with the shaft cylinder 1 to ensure that the lubricating oil inside the shaft cylinder 1 will not leak out, and at the same time to prevent external impurities from entering the shaft cylinder 1. The sealing oil seal 8 is detachably connected to the stepped groove 23 for easy replacement and maintenance.

[0024] like Figures 1-3 As shown, a rubber pad 9 is provided on the inner wall of the shaft cylinder 1 at the position that fits the bottom of the shaft cylinder 1. This pad is used to absorb and buffer the vibration and impact generated by the excavator during operation, and to protect the shaft cylinder 1 and the bushing 2 from damage.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
