DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0024] Please refer to Figures 1-5 The utility model provides a technical scheme: a municipal road foundation pit excavation device, which comprises: excavator arm 1 and excavator bucket 4, the outer wall of excavator arm 1 is provided with hydraulic cylinder 2, and hydraulic cylinder 2 is the main power source for driving the rotation of excavator bucket. Through the pressure change of hydraulic oil, the piston rod of hydraulic cylinder can extend or retract, and this linear motion is converted into the rotary motion of excavator bucket 4 through pull rod 3, so that excavator bucket can switch between different states such as excavation, loading and dumping.

[0025] The one end of the piston rod of hydraulic cylinder 2 is provided with pull rod 3, the one end of pull rod 3 is provided with excavator bucket connecting seat 5, the outer wall of pull rod 3 and the outer wall of excavator arm 1 are provided with connecting rod 6, the one side of excavator bucket connecting seat 5 is provided with excavator bucket 4, and the one side of the outer wall of excavator arm 1 is provided with double-head pneumatic cylinder 8. Through the extension and retraction of the piston rod thereof, the frame structure composed of upper connecting arm 9 and lower connecting arm 10 is driven to approach or move away from excavator bucket 4, so as to provide the necessary clamping force for vibration motor 11 and ensure that the vibration can be effectively transmitted to excavator bucket.

[0026] The two ends of the piston rod of double-head pneumatic cylinder 8 are provided with upper connecting arm 9, the bottom end of upper connecting arm 9 is provided with lower connecting arm 10, and the one side of lower connecting arm 10 is provided with vibration motor 11. High-frequency vibration is generated, and when closely attached to excavator bucket 4, these vibrations can effectively destroy the adhesion between the soil and the inner wall of excavator bucket, so as to loosen the soil particles and make them fall, thereby realizing the effective cleaning of the inner wall of excavator bucket and ensuring the continuity and efficiency of the excavation operation.

[0027] The outer wall of the excavator arm 1 is provided with a linear motor sliding rail 7, and a double-headed cylinder 8 is fixed on the sliding block of the linear motor sliding rail 7. The double-headed cylinder 8 and its attached components are responsible for vertical up-and-down movement, enabling the vibration motor 11 to accurately align with the position of the excavator bucket 4, thereby preparing for the cleaning of the soil on the inner wall of the excavator bucket.

[0028] The sliding block of the linear motor sliding rail 7 is fixed with bearing seats 12 on both sides, a rotating arm 13 is rotatably arranged between the bearing seats 12, and the double-headed cylinder 8 is fixedly connected to one side of the rotating arm 13. A servo motor 14 is fixed to the outer wall of the bearing seat 12 on one side, a rotating shaft is rotatably arranged between the bearing seats 12, the rotating arm 13 is fixed to the outer wall of the rotating shaft, and the output shaft of the servo motor 14 is fixedly connected to one end of the rotating shaft. The servo motor 14 is installed on the outer wall of the bearing seat 12 on one side and is fixedly connected to one end of the rotating shaft through its output shaft, driving the rotating arm 13 to accurately rotate in the horizontal plane. The servo motor has the characteristics of high precision, high reliability and fast response, and can realize accurate control of the rotation angle of the rotating arm 13, thereby meeting the needs of different excavation operations for position adjustment of the double-headed cylinder and its attached components. The rotating arm 13 serves as a bridge connecting the double-headed cylinder 8 and the servo motor 14, and not only transmits the driving force of the servo motor, but also allows the double-headed cylinder to rotate by a certain angle in the horizontal plane. This design increases the flexibility of the double-headed cylinder and its attached components such as the vibration motor 11, enabling them to better adapt to different excavation scenarios and excavator bucket shapes.

[0029] The pull rod 3 is rotatably connected to the hydraulic oil cylinder 2, and the pull rod 3 is rotatably connected to the connecting rod 6. The excavator arm 1 is rotatably connected to the connecting rod 6, the excavator arm 1 is rotatably connected to the excavator bucket connecting seat 5, and the excavator arm 1 is rotatably connected to one end of the hydraulic oil cylinder 2. The excavator bucket connecting seat 5 is provided with rotating shafts on both sides, and the excavator bucket connecting seat 5 is fixedly connected to the excavator bucket 4. The upper connecting arm 9 and the lower connecting arm 10 are connected by bolts, and the upper connecting arm 9 and the lower connecting arm 10 are provided with rubber buffer pads. The rubber buffer pads can absorb and disperse the vibration and impact force generated during excavation, protecting the upper connecting arm 9 and the lower connecting arm 10 from damage.

[0030] When the municipal road foundation pit excavation device is in use, the excavator cooperates with the excavator bucket 4 of the present application to excavate the foundation pit. During excavation, some soil may adhere to the inner wall of the excavator bucket 4, affecting the smooth progress of excavation. When the excavator bucket 4 needs to be cleaned, the hydraulic oil cylinder 2 is retracted by the excavator control, driving the excavator bucket 4 to rotate downward, then the linear motor sliding rail 7 is controlled to drive the double-headed cylinder 8 to descend, moving the vibration motor 11 to the outer wall of the excavator bucket 4, then the piston rod of the double-headed cylinder 8 is retracted, making the lower connecting arm 10 tightly adhere to the inner wall of the excavator bucket 4, and the vibration motor 11 is started to transmit vibration to the excavator bucket 4. Through vibration, the soil in the excavator bucket 4 falls, facilitating the smooth progress of excavation.

[0031] Based on the embodiments of the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the range of the utility model protection.
