[0032] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0033] Referring to Figures 1 - 3 , a high-frequency vibration longitudinal milling head for a milling excavator, comprising a support plate 1, a motor 2 is fixedly connected to the top of the support plate 1, a rotating column 3 is fixedly connected to the output end of the motor 2, a rotating disc 4 is rotatably connected to the bottom end of the rotating column 3, an eccentric wheel 5 is fixedly connected to the bottom end of the rotating disc 4, a second ball head 13 is rotatably connected to the inside of the eccentric wheel 5, a support column 6 is fixedly connected to the bottom of the support plate 1, a sliding table 8 is slidably connected to the outer wall of the support column 6, a spring 7 is sleeved on the outer wall of the support column 6, one end of the spring 7 is fixedly connected to the bottom of the support plate 1, the other end of the spring 7 is fixedly connected to the top of the sliding table 8, a slider 9 is slidably connected to the inside of the sliding table 8, a fixed column 10 is fixedly connected to the top of the slider 9, a first ball head 11 is rotatably connected to the inside of the fixed column 10, a connecting rod 12 is rotatably connected to the inside of the first ball head 11, one end of the connecting rod 12 is rotatably connected to the inside of the second ball head 13, and a rotating assembly is arranged inside the sliding table 8.
[0034] Specifically, when using this milling head, the rotating column 3 is driven to rotate by the output end of the motor 2, and then the rotating disc 4 at the bottom is driven to rotate under force. The rotating disc 4 transmits the force to the eccentric wheel 5 connected at the bottom, and the eccentric wheel 5 drives the second ball head 13 connected inside to rotate under force. The eccentric design of the eccentric wheel 5 causes a rotational difference during rotation, resulting in a slight up and down movement of the fixed column 10. The fixed column 10 drives the slider 9 connected at the bottom to move up and down, and at the same time, the slider 9 drives the sliding table 8 to slide slightly up and down on the outer wall of the support column 6. At the same time, the sliding table 8 squeezes and contracts the spring 7 connected at the top, and then the spring 7 rebounds, driving the sliding table 8 to reset, enabling the milling head to achieve the effect of high-frequency vibration, which helps to improve the cutting efficiency and working quality.
[0035] Referring to Figure 2 and Figure 3 , the rotating assembly includes a threaded column 14, the outer wall of the threaded column 14 is rotatably connected inside the sliding table 8, the inside of the slider 9 is threadedly connected to the outer wall of the threaded column 14, and a handle 15 is rotatably connected to one end of the threaded column 14.
[0036] Specifically, when it is necessary to adjust the vibration frequency, the operator can rotate the handle 15, and the force drives the threaded column 14 connected to one end to rotate inside the sliding table 8. At the same time, the movement of the threaded column 14 will also cause the slider 9 connected by the external thread to move, and the vibration frequency is adjusted by the movement of the slider 9, achieving the effect that the vibration frequency can be adjusted.
[0037] Refer to Figure 4 and Figure 5 As shown in and, a connecting frame 16 is provided at the bottom of the sliding table 8. A sliding column 17 is slidably connected inside the connecting frame 16. The outer wall of the sliding column 17 is slidably connected inside the sliding table 8. The top end of the sliding column 17 is fixedly connected with a threaded block 18. A first threaded rod 20 is threadedly connected inside the threaded block 18. The first threaded rod 20 is rotatably connected inside the sliding column 17. A tapered column 21 is fixedly connected to the outer wall of the first threaded rod 20. A nut 19 is fixedly connected to the top end of the first threaded rod 20. A clamping column 22 is provided inside the sliding column 17. The tapered column 21 is in contact with the clamping column 22. A second threaded rod 23 is fixedly connected to the bottom end of the tapered column 21. A sleeve 24 is fixedly connected inside the sliding column 17. The second threaded rod 23 is threadedly connected inside the sleeve 24.
[0038] Specifically, when it is necessary to quickly disassemble and assemble the milling head, the operator first inserts the sliding column 17 connected inside the connecting frame 16 into the clamping column 22. Subsequently, by turning the nut 19, the force on the nut 19 drives the first threaded rod 20 connected to the bottom to rotate inside the threaded block 18. Through the threaded connection between the threaded block 18 and the first threaded rod 20, the first threaded rod 20 moves inside the sliding column 17. At the same time, the first threaded rod 20 drives the tapered column 21 connected to the outer wall to move. During this process, the tapered column 21 exerts a force on the clamping column 22 inside the sliding column 17, causing the clamping column 22 to slide outward under the force and finally get stuck between the sliding table 8 and the sliding column 17 to complete the fixation, enabling the milling head to be quickly and safely disassembled and assembled, thereby improving the efficiency and flexibility of the operation.
[0039] Working principle: When using this milling head, the rotating column 3 is driven to rotate by the output end of the motor 2. The rotating column 3 drives the bottom turntable 4 to rotate under force. The turntable 4 drives the eccentric wheel 5 connected to the bottom to rotate under force. The eccentric wheel 5 drives the second ball head 13 connected inside to rotate under force. The second ball head 13 drives the connecting rod 12 to rotate under force. The connecting rod 12 drives the first ball head 11 connected to the bottom to rotate inside the fixed column 10 under force. Since the eccentric wheel 5 is eccentrically designed, a rotational difference will be generated during rotation, which causes the fixed column 10 to move under force. The fixed column 10 drives the slider 9 connected to the bottom to move up and down. The slider 9 drives the sliding table 8 to slide slightly up and down on the outer wall of the support column 6. At the same time, the sliding table 8 squeezes and contracts the spring 7 connected to the top. Subsequently, the spring 7 rebounds and drives the sliding table 8 to reset, thus achieving the effect that the milling head can vibrate at a high frequency. When it is necessary to adjust the vibration frequency, by rotating the handle 15, the handle 15 drives the threaded column 14 connected to one end to rotate inside the sliding table 8. At the same time, the threaded column 14 also drives the slider 9 threadedly connected to the outer wall to move. By moving the slider 9, the vibration frequency is adjusted, achieving the effect that the vibration frequency can be adjusted. When it is necessary to quickly disassemble and assemble the milling head, first insert the sliding column 17 connected inside the connecting frame 16 into the clamping column 22. Then, turn the nut 19. The nut 19 drives the threaded rod one 20 connected to the bottom to rotate inside the threaded block 18. Through the threaded connection between the threaded block 18 and the threaded rod one 20, the threaded rod one 20 moves inside the sliding column 17. At the same time, the threaded rod one 20 drives the tapered column 21 connected to the outer wall to move. During this process, the tapered column 21 squeezes the clamping column 22 inside the sliding column 17 under force, causing the clamping column 22 to slide outwards of the sliding column 17 under force and then be clamped between the sliding table 8 and the sliding column 17 to complete the fixation, thus achieving the effect that the milling head can be quickly disassembled and assembled.

Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
