Content of the Utility Model

[0004] The utility model discloses a paver for road construction, aiming to solve the technical problems that when dealing with asphalt paving on the road surface, in order to keep warm, the range of asphalt paving is small, and the flow direction of asphalt during the flowing process cannot be controlled, resulting in an uneven asphalt road surface. Even bubbles and cavities will appear in the uneven places, causing the collapse of the asphalt road surface.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

A plurality of installation holes are arranged on the surface of the installation plate. An asphalt pipe is fixedly connected through one side of the installation plate. An activity groove is arranged on one side of the paving plate;

[0007] Flow guiding mechanisms are respectively installed at both ends of the paving plate, and the flow guiding mechanisms are used to guide the flow of asphalt;

[0008] A main adjustment mechanism is installed on one side of the paving plate, and the main adjustment mechanism is used to control the flow of asphalt in the central area;

[0009] The main adjustment mechanism includes a first mounting rod fixedly connected to a position near the bottom of the movable groove on one side of the paving plate. One end of the mounting rod is rotatably connected to a first main board and a second main board respectively. A main intermediate board is fixedly connected to one side of the paving plate at the bottom position of the mounting rod. One end of the first main board is rotatably connected to a second left connecting plate and a first right connecting plate respectively. One end of the second main board is rotatably connected to a first left connecting plate and a second right connecting plate respectively. Sliding grooves are designed at one end of the first main board and the second main board respectively.

[0010] Auxiliary adjustment mechanisms are respectively installed on one side of the paving plate at positions on both sides of the main adjustment mechanism. The auxiliary adjustment mechanisms are used to adjust the flow of asphalt in the two side areas.

[0011] A control mechanism is installed on one side of the paving plate. The control mechanism is used to control the main adjustment mechanism and the auxiliary adjustment mechanisms.

[0012] The control mechanism includes a first motor and a second motor fixedly connected to one side of the paving plate near the movable groove. One end of the output shaft of the first motor is fixedly connected to a first threaded rod. One end of the output shaft of the second motor is fixedly connected to a second threaded rod. One end of the first threaded rod is threadedly connected to a first transmission block. One end of the second threaded rod is threadedly connected to a second transmission block. Stop rods are respectively fixedly connected to the tops of the first transmission block and the second transmission block.

[0013] In a preferred solution, the diversion mechanism includes baffle plates respectively fixedly connected to both ends of the paving plate. Resistance plates are respectively fixedly connected to the outer walls of both ends of the paving plate near the baffle plates.

[0016] Firstly, during the process of the paving plate pushing asphalt, the asphalt at the central position of the paving plate may flow to one side. If the asphalt flow deflects towards the side of the second main board, by controlling the rotation of the second motor, the second transmission block is driven to move back and forth, and the stop rod on the second transmission block drives the second main board to swing back and forth, so that the second main board pushes the asphalt flow back to the central position, maintaining the uniform paving of asphalt during asphalt paving. Similarly, if the asphalt flow deflects towards the side of the first main board, the stop rod on the first transmission block drives the first main board to swing back and forth, so that the first main board pushes the asphalt flow back to the central position, achieving the effect of controlling the flow direction of asphalt at the central position.

[0017] Second: If the offset of the asphalt at the central position is not controlled and the asphalt flow direction shifts to both sides, similarly, by controlling the first motor and the second motor, the first main board and the second main board are respectively controlled to rotate back and forth. The first left connecting plate and the second left connecting plate are respectively controlled by the second motor and the first motor. By separate control, the first auxiliary plate and the second auxiliary plate are realized, and the first auxiliary plate and the second auxiliary plate swing separately, controlling the asphalt flow direction.

[0025] A paver for road construction disclosed by the present utility model is mainly applied to the scenario where when laying asphalt on the road surface, the range for insulating the laid asphalt is small, and the flow direction during the asphalt flow cannot be controlled, resulting in an uneven asphalt road surface, and even bubbles and cavities may appear at the uneven places, causing the collapse of the asphalt road surface.

[0026] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A paver for road construction includes a paving plate 1. A mounting plate 4 is fixedly connected to the top of the paving plate 1. A plurality of mounting holes 3 are arranged on the surface of the mounting plate 4. An asphalt pipe 5 is fixedly connected through one side of the mounting plate 4. An activity groove 19 is arranged on one side of the paving plate 1;

[0027] Flow guiding mechanisms are respectively installed at both ends of the paving plate 1, and the flow guiding mechanisms are used to guide the flow of asphalt;

[0028] A main adjustment mechanism is installed on one side of the paving plate 1, and the main adjustment mechanism is used to control the flow of asphalt in the central area;

[0029] The main adjustment mechanism includes a first mounting rod fixedly connected to the position near the bottom of the activity groove 19 on one side of the paving plate 1. One ends of the mounting rod are respectively rotatably connected to a first main board 16 and a second main board 18. A main intermediate board 17 is fixedly connected to the position at the bottom of the mounting rod on one side of the paving plate 1. One ends of the first main board 16 are respectively rotatably connected to a second left connecting plate 12 and a first right connecting plate 20. One ends of the second main board 18 are respectively rotatably connected to a first left connecting plate 11 and a second right connecting plate 21. Sliding grooves 22 are respectively designed at one ends of the first main board 16 and the second main board 18.

[0030] Auxiliary adjustment mechanisms are respectively installed at the positions on both sides of the main adjustment mechanism on one side of the paving plate 1, and the auxiliary adjustment mechanisms are used to adjust the flow of asphalt in the two side areas;

[0031] A control mechanism is installed on one side of the paving plate 1, and the control mechanism is used to control the main adjustment mechanism and the auxiliary adjustment mechanism.

[0032] The control mechanism includes a first motor 7 and a second motor fixedly connected to one side of the laying plate 1 near the movable slot 19. One end of the output shaft of the first motor 7 is fixedly connected to a first threaded rod 9, and one end of the output shaft of the second motor is fixedly connected to a second threaded rod 10. One end of the first threaded rod 9 is threadedly connected to a first transmission block 8, and one end of the second threaded rod 10 is threadedly connected to a second transmission block. The tops of the first transmission block 8 and the second transmission block are respectively fixedly connected to a stop rod 23.

[0033] In this embodiment, the mounting plate 4 is fixed to the asphalt engineering vehicle through the mounting holes 3. The engineering vehicle is used for paving asphalt. By pouring asphalt into one end of the asphalt pipe 5, the asphalt will be heated during construction to reduce its viscosity, so that the asphalt will not solidify inside the asphalt pipe 5. The high-temperature asphalt flows inside the asphalt pipe 5 and flows out through the other end of the asphalt pipe 5, flowing onto the ground. The engineering vehicle moves forward, and the asphalt laid on the ground is spread by the laying plate 1, achieving the effect of paving the road surface with asphalt.

[0034] Refer to Figure 1 、 Figure 2 and Figure 3 In a preferred embodiment, the diversion mechanism includes flow-blocking plates 6 respectively fixedly connected to both ends of the laying plate 1, and resistance plates 2 are respectively fixedly connected to the outer walls of both ends of the laying plate 1 near the flow-blocking plates 6.

[0035] In this embodiment, when there is too much asphalt, the asphalt on both sides may overflow from both ends of the laying plate 1. Through the design of the flow-blocking plates 6, it is not easy for the asphalt to overflow during the paving process. The asphalt flows back to the center along the flow-blocking plates 6 and the laying plate 1. The function of the resistance plates 2 is to block the flow of the asphalt, so that a part of the asphalt flows to the auxiliary intermediate plate 14, increasing the amount of asphalt on both sides and preventing the asphalt on the road surface from being higher on both sides and lower in the middle during paving, achieving the effect of evenly paving the asphalt.

[0036] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In a preferred embodiment, the auxiliary adjustment mechanism includes second mounting rods respectively fixedly connected to the outer walls of both ends of the laying plate 1 near the resistance plates 2. One end of each second mounting rod is respectively rotatably connected to a first auxiliary plate 13 and a second auxiliary plate 15, and an auxiliary intermediate plate 14 is fixedly connected to the bottom of the outer wall of the laying plate 1 near the second mounting rods.

[0037] One end of the asphalt pipe 5 is located above the main intermediate plate 17. Bubble rods are provided at the bottoms of the first auxiliary plate 13, the second auxiliary plate 15, the first main plate 16 and the second main plate 18. One side of the first auxiliary plate 13 and the second auxiliary plate 15 are respectively rotatably connected to the first left connecting plate 11 and the second left connecting plate 12, and the other side of the first auxiliary plate 13 and the second auxiliary plate 15 are respectively rotatably connected to the first right connecting plate 20 and the second right connecting plate 21.

[0038] One end of the first threaded rod 9 is rotatably connected to one end of the second threaded rod 10. The stop rod 23 slides inside the sliding groove 22.

[0039] In this embodiment, since the asphalt is at a high temperature and its viscosity decreases, its fluidity increases. The function of the main intermediate plate 17 is to divide the asphalt into two halves and evenly lay it on the ground. During the process of the laying plate 1 pushing the asphalt, the asphalt at the center position of the laying plate 1 may flow to one side. If the asphalt flow deviates towards the second main plate 18 side, by controlling the rotation of the second motor, the second transmission block is driven to move back and forth, so that the stop rod 23 on the second transmission block drives the second main plate 18 to swing back and forth, so that the second main plate 18 pushes the asphalt flow towards the second main plate 18 side back to the center position, maintaining the even paving of the asphalt during paving. Similarly, if the asphalt flow deviates towards the first main plate 16 side, by controlling the rotation of the first motor 7, the first transmission block 8 is driven to move back and forth, so that the stop rod 23 on the first transmission block 8 drives the first main plate 16 to swing back and forth, so that the first main plate 16 pushes the asphalt flow towards the first main plate 16 side back to the center position, achieving the effect of controlling the flow direction of the asphalt at the center position.

[0040] Furthermore, due to the symmetrical design, there is a first auxiliary plate 13, an auxiliary intermediate plate 14 and a second auxiliary plate 15 on both sides of the laying plate 1. If the deviation of the asphalt at the center position is not controlled and the asphalt flow direction deviates and flows to both sides, similarly, by controlling the first motor 7 and the second motor, the first main plate 16 and the second main plate 18 are respectively controlled to rotate back and forth. Since the asphalt at the center position has deviated, the back-and-forth rotation of the first main plate 16 and the second main plate 18 has little effect. Through the functions of the first left connecting plate 11 and the second left connecting plate 12, the first left connecting plate 11 and the second left connecting plate 12 are respectively controlled by the second motor and the first motor 7. By controlling respectively, the first auxiliary plate 13 and the second auxiliary plate 15 are realized, and the first auxiliary plate 13 and the second auxiliary plate 15 are respectively swung to control the asphalt flow direction, or they can be swung together to push the asphalt flow forward, accelerating the asphalt flow and preventing the asphalt from solidifying during paving, achieving the effects of controlling the asphalt flow direction on both sides and preventing the asphalt from solidifying.

[0041] Working principle: When in use, the mounting plate 4 is fixed to the asphalt engineering vehicle through the mounting holes 3. The engineering vehicle is used for paving asphalt. One end of the asphalt pipe 5 is filled with asphalt. During construction, the asphalt will be heated to reduce its viscosity, so the asphalt will not solidify inside the asphalt pipe 5. The high-temperature asphalt flows inside the asphalt pipe 5 and flows out through the other end of the asphalt pipe 5, flowing onto the ground. The engineering vehicle moves forward, and the paving plate 1 spreads the asphalt laid on the ground, achieving the effect of paving asphalt on the road surface. Since the asphalt is heated and its viscosity decreases, its fluidity increases. The main intermediate plate 17 serves to divide the asphalt into two halves and evenly lay it on the ground. During the process of the paving plate 1 pushing the asphalt, the asphalt at the center position of the paving plate 1 may flow to one side. If the asphalt flow deviates towards the side of the second main board 18, by controlling the rotation of the second motor, the second transmission block moves back and forth, and the stop rod 23 on the second transmission block drives the second main board 18 to swing back and forth, causing the second main board 18 to push the asphalt flow towards the second main board 18 back to the center position, maintaining the even paving of the asphalt during paving. Similarly, if the asphalt flow deviates towards the side of the first main board 16, by controlling the rotation of the first motor 7, the first transmission block 8 moves back and forth, and the stop rod 23 on the first transmission block 8 drives the first main board 16 to swing back and forth, causing the first main board 16 to push the asphalt flow towards the first main board 16 back to the center position, achieving the effect of controlling the flow direction of the asphalt at the center position. Due to the symmetrical design, there is a first auxiliary plate 13, an auxiliary intermediate plate 14, and a second auxiliary plate 15 on both sides of the paving plate 1. If the deviation of the asphalt at the center position is not controlled and the flow direction of the asphalt deviates towards both sides, similarly, by controlling the first motor 7 and the second motor, the first main board 16 and the second main board 18 are respectively controlled to swing back and forth. Since the asphalt at the center position has already deviated, the back-and-forth rotation of the first main board 16 and the second main board 18 has little effect. Through the functions of the first left connecting plate 11 and the second left connecting plate 12, the first left connecting plate 11 and the second left connecting plate 12 are respectively controlled by the second motor and the first motor 7. By separate control, the first auxiliary plate 13 and the second auxiliary plate 15 are realized, achieving the separate swinging of the first auxiliary plate 13 and the second auxiliary plate 15, controlling the flow direction of the asphalt, or they can swing together to push the asphalt flow forward, accelerating the flow of the asphalt, preventing the asphalt from solidifying during paving, achieving the effects of controlling the flow direction of the asphalt on both sides and preventing the asphalt from solidifying. When there is too much asphalt, the asphalt on both sides may overflow from both ends of the paving plate 1. Through the design of the flow-blocking plate 6, during the paving process of the asphalt, it is not easy to overflow. The asphalt flows back to the center along the flow-blocking plate 6 and the paving plate 1. The resistance plate 2 serves to block the flow of the asphalt, causing a part of the asphalt to flow towards the auxiliary intermediate plate 14, increasing the amount of asphalt on both sides, preventing the asphalt on the road surface from being higher on both sides and lower in the middle during paving, achieving the effect of evenly laying the asphalt.
