[0020] The present invention relates to a multifunctional roadbed earthwork paver structure, such as Figures 1 to 7 As shown, including: Engineering vehicle 1, with sufficient carrying capacity and driving stability, independently fixed; The mounting base 2 is arranged at the rear of the engineering vehicle 1, and the mounting base 2 is bolted to the rear of the engineering vehicle 1 to ensure that the structure is stable and easy to install and disassemble; The mounting shaft 3 is disposed in the fixing hole of the mounting seat 2, and the mounting shaft 3 is free to rotate around the fixing hole of the mounting seat 2; The connecting member 4 is arranged on the installation shaft 3, the connecting member 4 is slidably installed along the length direction of the installation shaft 3, and the connecting member 4 rotates synchronously with the installation shaft 3; The stud 5 is disposed in the threaded inner hole of the connecting member 4, and the stud 5 is used to lock the connecting position between the connecting member 4 and the mounting shaft 3; The conveying pipe 6 is arranged on the connecting piece 4, and a discharge pipe 61 is arranged at the discharge port of the conveying pipe 6. The outlet direction of the discharge pipe 61 can be adjusted according to the construction needs to realize accurate material laying operation. An adding funnel 62 is arranged at the adding port of the conveying pipe 6 to facilitate adding materials into the conveying pipe 6. The conveying mechanism 7 is arranged on the conveying pipe 6 and is used to guide the material from the adding funnel 62 to the discharging pipe 61 to realize continuous material laying operation; The driving mechanism 8 is arranged in the inner cavity of the mounting seat 2 and is used to install the shaft 3 to provide reciprocating swing power. The swing frequency and amplitude of the driving mechanism 8 can be adjusted according to the construction needs to realize the paving operation of different widths and thicknesses: The working principle of this device is as follows: During paving operations, materials are added to the conveying pipe 6 through the adding funnel 62, and the conveying mechanism 7 guides the materials from the adding port to the discharging pipe 61 to ensure that the materials can be continuously conveyed to the paving position. The driving mechanism 8 is started to provide reciprocating swinging power for the installation shaft 3. The swinging frequency and amplitude of the driving mechanism 8 are set according to actual construction needs to adapt to paving operations of different widths and thicknesses. The operator drives the engineering vehicle 1 forward so that the materials can be laid on the ground according to the predetermined design. When the paving of a section is completed, the conveying mechanism 7 and the driving mechanism 8 are closed; the driving mechanism 8 provides reciprocating swinging power for the installation shaft 3, and the flexible adjustment of the discharging port of the conveying pipe 6 is realized, so that the paving operation can be carried out quickly and continuously according to construction needs. Compared with traditional manual and simple mechanical equipment, the present invention greatly improves the construction efficiency and shortens the construction period.

[0021] As a preferred solution, Figures 2 to 7 As shown, the driving mechanism 8 includes: The positioning beam 81 is arranged in the inner cavity of the mounting seat 2, and a slide groove is arranged on the positioning beam 81 along the length direction; The moving member 82 matches the slide slot, is disposed inside the slide slot of the positioning beam 81, and is slidably installed along the length direction of the slide slot. The moving member 82 is provided with a connecting mechanism 83; A spur rack 84 is disposed on the moving member 82, and the length direction of the spur rack 84 is parallel to the length direction; The transmission gear 85 is coaxially arranged on the mounting shaft 3, and the transmission gear 85 is meshed with the spur rack 84. When the spur rack 84 rotates, the linear motion is converted into the rotation of the transmission gear 85 through the meshing relationship with the transmission gear 85. The power mechanism 86 is disposed in the inner cavity of the mounting seat 2 and is used to provide displacement power to the moving member 82; The transmission mechanism 87 is disposed in the inner cavity of the mounting seat 2 and is used to convert the rotation of the power mechanism 86 into the linear movement of the moving member 82; The limiting mechanism 88 is arranged in the inner cavity of the mounting seat 2, and the limiting mechanism 88 is used to guide the transmission mechanism 87; The working principle of the driving mechanism 8 of this device is as follows: When the power mechanism 86 is started, its output shaft converts the rotation into the linear movement of the moving part 82 through the transmission mechanism 87. When the moving part 82 slides in the slide groove, it drives the spur rack 84 to move together. The teeth of the spur rack 84 mesh with the transmission gear 85. When the spur rack 84 moves, the movement is converted into the rotation of the transmission gear 85 through the meshing relationship with the transmission gear 85. The transmission gear 85 is coaxially arranged on the installation shaft 3. Therefore, when the transmission gear 85 rotates, it will drive the installation shaft 3 to rotate together to realize the reciprocating swing of the installation shaft 3. By adjusting the output power of the power mechanism 86 and the transmission ratio of the transmission mechanism 87, the swing frequency and amplitude of the installation shaft 3 can be accurately controlled to adapt to paving operations of different widths and thicknesses.

[0022] As a preferred solution, Figures 2 to 7 As shown, the power mechanism 86 includes: The power shaft 86a is rotatably disposed in the inner cavity of the mounting seat 2, and the rotation axis of the power shaft 86a is perpendicular to the rotation axis of the mounting shaft 3 to ensure that it can rotate smoothly; A worm gear 86b is coaxially disposed on the power shaft 86a; The servo motor 86c is disposed in the inner cavity of the mounting seat 2, and the rotation axis of the servo motor 86c is perpendicular to the rotation axis of the power shaft 86a; The worm 86d is disposed at the output end of the servo motor 86c, and the worm 86d is meshedly connected with the worm wheel 86b; The working principle of the power mechanism 86 of this device is as follows: When the servo motor 86c is started, its output shaft drives the worm 86d to rotate, and the rotation of the worm 86d is transmitted to the worm wheel 86b through the meshing relationship, thereby driving the power shaft 86a to rotate. The rotation of the power shaft 86a is converted into the linear movement of the moving part 82 through the transmission mechanism 87. The meshing of the worm 86d and the worm wheel 86b makes the transmission have a self-locking function, thereby ensuring that the position of the conveying pipe 6 will not rotate when the servo motor 86c is not in working state.

[0023] As a preferred solution, Figures 2 to 7 As shown, the worm 86d is rotatably disposed in the inner hole of the auxiliary member 86e, and the auxiliary member 86e is disposed in the inner cavity of the mounting seat 2; The design of the auxiliary member 86e provides effective support for the worm 86d, ensuring its stability and accuracy under high-load working conditions.

[0024] As a preferred solution, Figures 2 to 7 As shown, the limiting mechanism 88 includes: The support frame 88a is made of high-strength steel and is disposed in the inner cavity of the mounting seat 2. The power shaft 86a is rotatably connected to the through hole of the support frame 88a. The fixed gear 88b is disposed on the support frame 88a, and the axis of the fixed gear 88b coincides with the axis of the power shaft 86a; The transmission mechanism 87 comprises: The mounting frame 87a is disposed on the power shaft 86a, and provides a stable platform. A first gear 87b is rotatably disposed on the mounting frame 87a, and the first gear 87b is meshed and connected with a fixed gear 88b; The auxiliary shaft 87c is rotatably disposed in the through hole of the mounting frame 87a, and a second gear 87d is coaxially disposed at one end of the auxiliary shaft 87c, and the second gear 87d is meshed and connected with the first gear 87b; The transmission beam 87e is arranged at the other end of the auxiliary shaft 87c, and the transmission beam 87e is installed in cooperation with the connecting mechanism 83, and is used for the connecting mechanism 83 to drive the moving member 82 to swing back and forth; The working principle of this device is as follows: When the servo motor 86c is started, its output shaft drives the worm 86d to rotate, and the worm 86d then rotates the power shaft 86a through the meshing relationship with the worm wheel 86b. The rotation of the power shaft 86a is transmitted to the first gear 87b through the fixed gear 88b, and then further transmitted to the auxiliary shaft 87c through the meshing between the first gear 87b and the second gear 87d. The rotation of the auxiliary shaft 87c causes the reciprocating swing of the transmission beam 87e, and this swing acts on the moving part 82 through the connecting mechanism 83, so that the mounting shaft 3 can reciprocate according to the set frequency and amplitude; wherein the power is transmitted to the transmission beam 87e by the meshing of the first gear 87b and the second gear 87d, so that the traction force is driven and transmitted in a triangular structure. This design ensures that when the connecting part 83 moves, the moving trajectory is guided to ensure the smoothness of the movement and prevent jamming.

[0025] As a preferred solution, Figures 2 to 7 As shown, the connecting mechanism 83 includes: The conductive member 83a is disposed on the movable member 82, and a guide groove is disposed in the length direction of the conductive member 83a; The slider 83b is disposed inside the guide groove of the transmission member 83a, and the slider 83b is slidably installed along the guide groove, and the transmission beam 87e is rotatably connected to the slider 83b; The adjusting mechanism 83c is provided on the conductive member 83a and is used to adjust the connection position between the slider 83b and the conductive member 83a so as to adjust the swing amplitude of the moving member 82; The adjustment mechanism 83c includes: The threaded rod 83c1 is rotatably mounted on the conductive member 83a, and the threaded through hole of the slider 83b is mounted in cooperation with the threaded rod 83c1. When the threaded rod 83c1 rotates, the slider 83b is driven to move in the guide groove; The driving motor 83c2 is arranged on the conductive member 83a, and the output end of the driving motor 83c2 is coaxially mounted with the threaded rod 83c1; The working principle of the connecting mechanism 83 of this device is as follows: When the transmission beam 87e of the transmission mechanism 87 swings, it transmits the swinging power to the slider 83b through the rotating connection. Under the action of the swinging power, the slider 83b drives the conductive member 83a to move synchronously, thereby driving the spur rack 84 to move. By controlling the rotation of the threaded rod 83c1 through the driving motor 83c2 in the adjustment mechanism 83c, the position of the slider 83b can be accurately adjusted, thereby changing the swing amplitude of the moving member 82. This design enables the connecting mechanism 83 to flexibly adapt to different construction requirements, thereby improving the adaptability and work efficiency of the paver.

[0026] As a preferred solution, Figure 3 As shown, the conveying mechanism 7 includes: The spiral conveying blade 71 is disposed inside the conveying pipe 6, and the spiral conveying blade 71 is rotatably connected to the inner wall of the conveying pipe 6; A power motor 72 is provided on the conveying pipe 6 and is used to provide a rotational force to the spiral conveying blade 71; The working principle of the conveying mechanism 7 of this device is as follows: During the paving operation, when the material is added into the conveying pipe 6 through the adding funnel 62, the power motor 72 starts and drives the spiral conveying blade 71 to start rotating. The rotation of the spiral conveying blade 71 conveys the material continuously and stably along the axial direction of the conveying pipe 6 to the discharge pipe 61. Due to the spiral design of the spiral conveying blade 71, the material will be effectively compressed and mixed during the conveying process, thereby improving the uniformity and density of the paving.

[0027] As a preferred solution, Figures 1 to 3 As shown, the conveying pipe 6 and the connecting member 4 are installed obliquely, and the discharge pipe 61 is located at the lower end of the conveying pipe 6; The inclined installation method enables the material to flow downward along the conveying pipe 6 more smoothly under the action of gravity, reducing the risk of material blockage during the conveying process, thereby improving the material conveying efficiency.
