[0051] A four-stage vibration reduction mechanism, which is arranged on the top of the vibration excitation mechanism 1, and the top of the mechanism abuts against the connecting seat;

[0052] The five-stage vibration reduction mechanism is arranged between the vibration exciting mechanism 1 and the lower swing bracket 4 .

[0053] The high-frequency vibration breaker device of the present invention can achieve the isolation of vibration between the excitation mechanism and the excavator mechanical arm through the arrangement of five-level vibration reduction mechanisms, reduce the damage to the connection between the two and the excavator mechanical arm, extend the service life, and increase the up and down impact force and impact frequency of the breaker hammer head, thereby ensuring stable crushing efficiency. Among them, the first-level vibration reduction mechanism is a shell structure connecting the excitation mechanism and the excavator mechanical arm, which is sleeved on the excitation mechanism and hinged with the two at multiple locations, and realizes vibration unloading and buffering through rotation between structures and deformation within the structure; the second-level vibration reduction mechanism is arranged at the structural hinge, which can reduce the influence of vibration at this location and reduce extrusion and wear between structures; the third-level vibration reduction mechanism, the fourth-level vibration reduction mechanism, and the fifth-level vibration reduction mechanism act on the surface of the excitation mechanism and the first-level vibration reduction mechanism, limit the rotation range of the two, and buffer the activity, and limit them laterally to avoid displacement along the axial direction of the hinge axis when the two rotate, ensuring stable rotation and non-destructive activity of the structure.

[0054] The upper swing bracket 3 includes a first annular base frame 31, and first connecting holes 32 are arranged on both sides of the first base frame 31.

[0055] The other end of the first base frame 31 is provided with a limit hole 35, and the limit block extending from the inside of the connecting shell is slidably arranged in the limit hole 35. According to the design, when the excitation mechanism 1 generates mechanical vibration and the quadrilateral structure formed by the excitation mechanism 1, the two swing brackets and the connecting shell are deformed, the limit hole 35 and the limit block cooperate with the vibration reduction mechanism to limit the range of motion of the quadrilateral structure, so that the impact force and frequency of the crushing hammer head 2 are increased, thereby ensuring stable crushing efficiency.

[0056] The four-stage vibration reduction mechanism is an air spring assembly 7, which includes an air bag 71 with pressure plates arranged on the upper and lower end surfaces, a base 72 positioned at the bottom of the air bag 71, a plurality of reinforcing ribs radiating from the side of the base 72, and a connecting plate 73 extending from the bottom thereof, which is inserted into and positioned in the installation gap 14 between the hinge seat 11 and the first sleeve 12. The four-stage vibration reduction mechanism is tightly embedded and assembled on the excitation mechanism 1 through the connecting plate 73 to ensure its stable buffering effect. The vibration reduction mechanism adopts an air spring to improve the vibration reduction and buffering capabilities.

The middle part of the second base frame 41 is provided with a third sleeve 43, and the fourth hinge shaft 44 is rotatably arranged in the third sleeve 43.

[0060] The upper swing bracket 3 is provided with a lower hanging plate 36, the lower swing bracket 4 is provided with an upper extension plate 45, and the three-stage vibration reduction mechanism includes a vibration reduction block 6, which is positioned outside the lower hanging plate 36 and the upper extension plate 45. The vibration reduction block 6 can be a damper.

[0061] The working principle of a high-frequency vibration breaker device with five-level vibration reduction in this embodiment includes: when in use, the excavator arm moves the breaker device to the surface of the object to be broken, and the exciting mechanism 1 runs to form mechanical vibration. Through the quadrilateral structure formed by the excitation mechanism 1, the upper swing bracket 3, the lower swing bracket 4, and the connecting shell, the exciting mechanism 1 vibrates up and down relative to the excavator arm, and synchronous vibration reduction is performed to reduce the vibration transmitted to the excavator arm. When the exciting mechanism 1 moves downward, the lower swing bracket 4 rotates and moves upward relative to the exciting mechanism 1, so that the first positioning plate 81 and the limit frame 84 are close to and contacted, and buffering and vibration reduction are achieved through the buffer strip 83. When the exciting mechanism 1 moves upward, it approaches the connecting shell, and the connecting shell contacts the air spring assembly 7 on its top to achieve buffering and vibration reduction. During this period, the rubber damping sleeve 5 reduces vibration and buffers the hinge of the quadrilateral structure, and the vibration reduction block 6 laterally limits the exciting mechanism 1 and the connecting shell.
