[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: an adjustable excavator support, including a connecting base plate 1, an adjustment mechanism is provided on the top of the connecting base plate 1, a support frame 11 is fixedly connected to the top of the adjustment mechanism, a support base plate 12 is fixedly connected to the top of the support frame 11, and a shock absorption mechanism is provided on the outside of the support base plate 12.

[0025] The adjustment mechanism includes two connecting blocks 2, which are fixedly connected to the top of the connecting base plate 1. A rotating arc ring 10 is rotatably connected to the outside of the connecting blocks 2. The connecting blocks 2 provide a fulcrum for the rotation of the rotating arc ring 10. Two rotating plates 9 are rotatably connected to the other end of the rotating arc ring 10. A rotating shaft 8 is fixedly connected to the outside of the two rotating plates 9. The rotating plates 9 rotate with the rotating shaft 8. A telescopic component for extension and retraction is slidably connected to the outside of the rotating shaft 8. The rotating arc ring 10 is used to flexibly change its curvature according to the rotation of the rotating shaft 8, thereby causing the entire telescopic component to deform in coordination and achieve precise adjustment of the support height.

[0026] The telescopic assembly includes a second sliding frame 4, which is externally slidably connected to the outside of the rotating shaft 8. An inner sliding frame 3 is slidably connected to the inside of the second sliding frame 4, with its bottom slidably connected to the top of the connecting base plate 1. An outer sliding frame 5 is slidably connected to the outside of the second sliding frame 4. The second sliding frame 4, during adjustment, flexibly changes its position based on the dual guidance of the rotating shaft 8 and the first sliding frame 3, achieving relative sliding with other sliding frames to assist in adjusting the bracket height. The first sliding frame 3 cooperates with the second sliding frame 4 to share some of the stress during adjustment. The outer surface of the third sliding frame 5 is fixed. A connecting support plate 6 is connected, and a double-headed motor 7 is fixedly connected to the outside of the connecting support plate 6. The driving end of the double-headed motor 7 drives the rotating shaft 8 to rotate. The driving end of the double-headed motor 7 is fixedly connected to the outside of the rotating shaft 8. Another connecting block 2 is fixedly connected to the bottom of the support frame 11. Another rotating arc ring 10 is rotatably connected to the outside of the connecting block 2. The sliding frame 3 5 is used to move with the sliding frame 2 4, driving the upper support frame 11 to rise and fall. The rotating shaft 8 is used as the axis of the rotating plate 9 and the driving support component of the double-headed motor 7. The support frame 11 is used to bear the pressure from the supporting base plate 12.

[0027] Reference Figure 1 , Figure 3 and Figure 4 The shock absorption mechanism includes a second fixed disc 19, which is externally fixedly connected to the inside of the support base plate 12. A telescopic pressure rod 17 is fixedly connected to the top of the second fixed disc 19. The second fixed disc 19 serves as a fixed support point for the bottom of the telescopic pressure rod 17. When vibration occurs, it bears the impact force from above and transmits the vibration to the telescopic pressure rod 17. During the vibration transmission process, the telescopic pressure rod 17 automatically extends and retracts according to the vibration amplitude, cooperating with the buffer spring 18 to absorb the vibration energy. A first fixed disc 16 is fixed to the top of the telescopic pressure rod 17, and a connecting plate 13 is fixed to the outside of the first fixed disc 16. The connection between the first fixed disc 16 and the second fixed disc 19 is the outer connection between the telescopic pressure rod 17 and the support base plate 12. The unit is equipped with a buffer spring 18, which uses its own elastic properties to absorb energy to the maximum extent when vibration occurs, weakening the vibration intensity and protecting the equipment from damage. The fixed disc 16 is used to drive the connecting plate 13 in linkage. The connecting plate 13 has multiple fixed connection holes 15. The bottom of the connecting base plate 1 is fixedly connected to the connecting collar 14. The connecting base plate 1 is used to connect the base plate 1 to the corresponding part of the excavator by means of the connecting collar 14 at the bottom, providing a solid foundation for the subsequent stable operation of the support system and bearing the force transmitted by the upper components. The connecting plate 13 has multiple fixed connection holes 15 for connecting the upper control body and other components.

[0028] Working principle: The connecting base plate 1 is securely connected to the corresponding part of the excavator through the connecting collar 14 at its bottom, ensuring that the entire support system is tightly integrated with the excavator. The dual-head motor 7 supported by the connecting support plate 6 drives the rotating shaft 8 fixedly connected to it to rotate. As the rotating shaft 8 rotates, the rotating plate 9 rotates under the combined action of the rotating shaft 8 and the rotating arc ring 10 connected to it. One end of the rotating arc ring 10 is rotatably connected to the connecting block 2, thereby pushing the distance between the two connecting blocks 2. The sliding frame 2 4 slides along the rotating shaft 8, while the sliding frame 3 slides on the top of the connecting base plate 1. The relative sliding of the two realizes the change of the overall length of the telescopic component, thereby pushing the sliding frame 3 5 to rise or fall the connecting support frame 11 and the support base plate 12, so as to adjust the height of the support to adapt to different excavation operation height requirements.

[0029] When the excavator vibrates during operation, the vibration is transmitted to the support base plate 12, and the fixed disc 19 vibrates accordingly. The telescopic pressure rod 17 on the fixed disc 19 will extend and retract accordingly. The buffer spring 18 sleeved between the fixed disc 16 at the top of the telescopic pressure rod 17 and the fixed disc 19 at the bottom begins to function. The buffer spring 18 absorbs the vibration energy by its own elastic deformation, reducing the impact of vibration on the excavator and the support system itself. At the same time, the fixed connection hole 15 inside the connecting plate 13 is used to connect the upper control body.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
