Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0022] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, this utility model proposes a composite soundproof excavator cab, including an outer frame 1 and a soundproofing mechanism located on the inner wall of the outer frame 1. The soundproofing mechanism includes an inner frame 5 fixed to one side of the inner wall of the outer frame 1. Multiple hooks 15 are fixedly connected to one side of the inner frame 5, and soundproofing layers 16 are snapped onto the outer walls of each hook 15. By setting the inner frame 5, a stable foundation is provided for the installation of the soundproofing layers 16, ensuring that the soundproofing layers 16 can be accurately installed in the predetermined position, allowing the soundproofing layers 16 to fully exert their soundproofing effect. At the same time, the connection method between the inner frame 5 and the outer frame 1 ensures the overall soundproofing of the excavator cab. The stability of the cockpit structure allows the sound insulation mechanism to work in conjunction with other parts of the cockpit. The outer walls of the cockpit are secured with sound insulation layers 16 by hooks 15. The snap-fit ​​method ensures a tight connection between the sound insulation layers 16 and the inner frame 5, preventing the sound insulation layers 16 from becoming loose or shifting, thus ensuring the stability of the sound insulation effect. The sound insulation layers 16 use special sound insulation materials, such as XPS boards, which have good sound absorption and sound insulation properties and can effectively block the entry of external noise. When external noise is transmitted to the sound insulation layers 16, the microstructure inside the sound insulation layers 16 will cause the sound waves to be reflected and refracted multiple times, consuming the energy of the sound waves and thus reducing the intensity of the noise.

[0027] In addition, such as Figure 2 , Figure 3 and Figure 4As shown, buffer mechanisms are provided at both the upper and lower ends of one side of the outer wall of the inner frame 5. Each buffer mechanism includes connecting rods 6 fixed to the upper and lower ends of one side of the outer wall of the inner frame 5. Support frames 7 are fixedly connected to the ends of multiple connecting rods 6 away from the inner frame 5. The connecting rods 6 act as a bridge connecting the inner frame 5 and the support frame 7, firmly connecting them together and ensuring the stability between the buffer mechanism and the inner frame 5. The support frame 7 provides a solid support platform for subsequent buffer components, ensuring the normal operation of the entire buffer mechanism. Multiple sliding plates 9 are slidably connected to one side of the outer wall of each support frame 7. Push blocks 10 are fixedly connected to one side of each sliding plate 9. The push blocks 10 are grouped in pairs, and a spring rod 11 is fixedly connected between each pair of push blocks 10. The sliding plates 9 can slide freely on the support frame 7, allowing the push blocks 10 to move flexibly according to external vibrations. By setting the spring rod 11, the spring rod 11 is used to prevent the excavator from moving during operation. When vibration occurs, it is transmitted to the buffer mechanism through the outer frame 1 and inner frame 5. At this time, the spring rod 11 undergoes elastic deformation to absorb and buffer the vibration energy, effectively reducing the impact of vibration on the internal structure of the cockpit and protecting the integrity of the sound insulation layer 16 and other components. Multiple push blocks 10 are fixedly connected to connecting blocks 12 at the ends away from the spring rod 11. Connecting joints 13 are fixedly connected to one side of the outer wall of multiple connecting blocks 12. Multiple connecting joints 13 are grouped in pairs, and a top rod 14 is fixedly connected to one side of the outer wall of each group of connecting joints 13. The top rod 14 can transmit the vibration to the connecting joints 13 and connecting blocks 12, and then buffer it through the spring rod 11. This multi-stage transmission and buffering structure design allows the vibration to be absorbed and dispersed more fully, further improving the buffering effect. At the same time, the connection method of connecting blocks 12 and connecting joints 13 ensures the tightness and stability of the connection between various components, avoiding the loosening or falling off of components during vibration.

[0028] And, as Figure 2 and Figure 3As shown, a connecting mechanism is provided on one side of multiple sound insulation layers 16. The connecting mechanism includes multiple spring terminals 17 fixed to one side of the sound insulation layer 16. A fixing block 18 is fixedly connected to the end of the multiple spring terminals 17 away from the sound insulation layer 16. An external fixing plate 8 is fixedly connected to the end of the multiple fixing blocks 18 away from the spring terminals 17. The multiple external fixing plates 8 are all fixedly connected to one side of the inner wall of the outer frame 1. The spring terminals 17 have a certain elasticity and can buffer the vibration and impact force received by the sound insulation layer 16 to a certain extent. When the cockpit is subjected to external impact or vibration, the spring terminals 17 It will undergo elastic deformation, absorb some energy, reduce the direct impact on the sound insulation layer 16, thereby protecting the structural integrity of the sound insulation layer 16, extending its service life, and indirectly reducing the noise generated during vibration. By setting the external fixing plate 8, the sound insulation layer 16 is stably connected to the outer frame 1. The external fixing plate 8 provides reliable fixed support for the sound insulation layer 16, ensuring that the sound insulation layer 16 can be tightly attached to the inner wall of the outer frame 1, further enhancing the sound insulation effect. At the same time, this connection method also facilitates the overall inspection and maintenance of the sound insulation layer 16 when needed.

[0029] It should be noted that, as Figure 1 As shown, a window 2 is fixedly connected to one side of the outer wall of the outer frame 1, and a door 3 is fixedly connected to the other side of the outer wall of the outer frame 1. A base 4 is fixedly connected to the bottom of the outer frame 1. The window 2 and door 3 make it more convenient for the driver to operate the excavator. The base 4 allows the device to be better fixed to the excavator.

[0030] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
