[0002] With the continuous advancement of transportation infrastructure construction, the requirements for road surface quality are becoming increasingly stringent. The spreading and leveling of asphalt mixtures are key steps in road construction. Traditional construction methods often rely on manual labor, which is not only inefficient but also difficult to ensure the smoothness and compaction of the road surface. Manual paving is prone to problems such as uneven thickness and ragged edges, while uneven compaction can also lead to unstable road surface quality.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 2 The present invention provides an embodiment of an asphalt mixture paving and leveling device for road construction, comprising a paver box 1. Made of durable stainless steel, the paver box 1 is rectangular in shape and possesses sufficient capacity and strength to accommodate a large amount of asphalt mixture. Its primary function is to serve as a storage and preliminary processing container for the asphalt mixture, providing a stable material supply for subsequent paving operations. An auger 5 is rotatably connected to the interior of the paver box 1, uniformly mixing the asphalt mixture that enters it, causing the asphalt to fall evenly within the paver box 1, thereby improving the quality of the paved road surface.

[0032] Reference Figure 1 and Figure 3, the interior of the paver box 1 is rotatably connected to two baffles 6, whose main function is to control the outflow of the asphalt mixture when needed. When the baffles 6 are in the closed state, the asphalt mixture can be prevented from flowing out of the paver box 1 so that sufficient mixing preparation can be carried out. The interior of the paver box 1 is fixedly connected to an L-shaped partition plate 4, which is used to separate the asphalt box and the internal control structure to prevent it from affecting the internal structure. The tops of the two baffles 6 are rotatably connected to a rotating plate 1 7. The rotating plate 1 7 is rectangular and is used to pull the two baffles 6 to produce an opening and closing movement to control the falling of asphalt. The right side of the L-shaped partition plate 4 is rotatably connected to an electric push rod 11. The electric push rod 11 is used to control the rotation of the subsequent structure to open and close the baffles 6. The right side of the L-shaped partition plate 4 is rotatably connected to a rotating part 2 10. The rotating shaft of the rotating part 2 10 is set in the center. The two baffles 6 are driven to rotate synchronously through rotation. The right side of the rotating part 2 10 is rotatably connected to two rotating plates 2 9. The lengths of the two rotating plates 2 9 are different. Their function is to pull the subsequent structure to rotate. The right side of the L-shaped partition plate 4 is rotatably connected to two rotating parts 1 8. The rotating shafts of the two rotating parts 1 8 are set on the adjacent side, which plays a role in changing the direction of the rotating force. The front side of the paver box 1 is fixedly connected to a protective shell 19. The protective shell 19 is used to protect the construction workers from being injured by splashing asphalt during construction. The interior of the protective shell 19 is provided with a sliding component for leveling the asphalt.

[0033] Reference Figures 1 to 3 The driving end of the electric push rod 11 is rotatably connected to the front side of the rotating member 2 10. The driving end of the electric push rod 11 is connected to the rotating member 2 10, and can convert linear motion into rotational motion of the rotating member 2 10 during operation. The left side of the rotating member 2 10 is rotatably connected to the left side of the two rotating members 1 8, thereby achieving synchronous control of the rotation of the rotating member 8 by the rotating member 2 10. The left sides of the two rotating plates 1 7 are respectively rotatably connected to the right side of the two rotating members 8. The rotation of the rotating members 1 8 drives the movement of the rotating plates 1 7, which in turn controls the opening and closing of the two baffles 6. The adjacent sides of the two baffles 6 are in contact. The bottom of the paving machine box 1 is fixedly connected to the wheel 2. The wheel 2 is composed of rubber and metal and has good wear resistance and load-bearing capacity. There are two wheels 2, which are evenly distributed at the bottom of the paver box 1, so that the paver box 1 can move smoothly on the road surface. The outside of the paver box 1 is rotatably connected to a handle 3. The rotating connection method of the handle 3 allows the operator to adjust the angle of the handle 3 as needed, which is convenient for operating and pushing the paver box 1.

[0034] Reference Figure 1 and Figure 4The sliding assembly includes a mounting plate 12, the outside of the mounting plate 12 is fixedly connected to the inside of the protective shell 19, and the mounting plate 12 serves as the installation base of the sliding assembly to provide stable support for other components. The internal sliding connection of the mounting plate 12 is connected to two T-shaped sliders 16, and the T-shaped sliders 16 can slide smoothly in the mounting plate 12 to drive the subsequent structure to move back and forth. The bottom of the two T-shaped sliders 16 is fixedly connected to a paving plate 17. The function of the paving plate 17 is to evenly spread the asphalt mixture flowing out of the paver box 1 on the road surface to ensure the flatness of the road surface. The bottom of the mounting plate 12 is fixedly connected to a motor 13, which provides a power source for the reciprocating sliding mechanism. The driving end of the motor 13 is fixedly connected to an eccentric wheel 14. The eccentric wheel 14 is in the electric The eccentric wheel 14 is driven by the motor 13 and rotates, converting the rotary motion of the motor 13 into reciprocating motion. The bottom of the eccentric wheel 14 is rotatably connected to the pulling plate 15. The pulling plate 15 serves as a transmission structure and can transmit power to the T-shaped slider 16. The right side of the pulling plate 15 is rotatably connected to the left side of one of the T-shaped sliders 16. Through their rotational connection, the sliding of the T-shaped slider 16 is controlled, and the paving plate 17 of the driving part frictionally paves the ground. The internal rotation of the protective shell 19 is connected to the pressure wheel 18. The pressure wheel 18 is usually cylindrical and made of heavier metal. The pressure wheel 18 can rotate freely in the protective shell 19. When the asphalt mixture passes under the pressure wheel 18, the pressure wheel 18 compacts it. The top of the eccentric wheel 14 contacts the bottom of the mounting plate 12.

[0035] Working principle: First, the construction workers place the device on the road surface that needs to be worked on, and pour hot melt asphalt into the interior of the paver box 1. The internal auger 5 rotates to evenly mix the asphalt inside the paver box 1, and then turns on the switch of the electric push rod 11. The driving end of the electric push rod 11 extends and moves, driving the rotating part 2 10 to rotate, thereby driving the two rotating parts 2 10 to rotate, and then pulling the two rotating parts 1 8 to rotate on the right side of the L-shaped partition plate 4, further pulling the rotating plate 1 7 to rotate, thereby pulling the two baffles 6 to rotate and open, and releasing the asphalt inside the paver box 1 evenly, preventing the asphalt inside the paver box 1 from falling off during construction without time to be evenly mixed and paved, causing the ground asphalt to be unevenly paved for the first time, making the paved road surface smoother and improving the quality of the project.

[0036] Secondly, the fallen asphalt moves to the bottom of the pressure wheel 18 on the rear side through the movement of the device, and is rolled by the pressure of the pressure wheel 18 to compact the asphalt. Then, by turning on the switch of the motor 13, the eccentric wheel 14 at the bottom is driven to rotate, and then one end of the pulling plate 15 is pulled to make a circular motion, and finally the T-shaped slider 16 is pulled to make a reciprocating sliding motion, so that the paving board 17 contacts the ground and slides back and forth to smooth the ground, thereby improving the flatness of the road surface, reducing bumps during vehicle driving, improving driving comfort and safety, ensuring that the slope and elevation of the road surface meet the design requirements, facilitating drainage and avoiding water accumulation, and further enhancing the performance of the road surface.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
