[0003] The existing patent (publication number: CN220413944U) discloses a rolled asphalt mixture thin layer overlay paving equipment, including a support frame, a mounting ring connected to the paving equipment is installed on the front of the support frame, a rotatable auger and a rolling roller are installed inside the support frame, the support frame is provided with an opening at the top of the auger, and a top plate is provided at the top of the rolling roller, the auger includes a first auger and a second auger, when the first auger and the second auger rotate at the same time, the first auger distributes the asphalt to both sides.

[0004] The above-mentioned comparative document points out that the device of the utility model solves the problem that the existing rolled asphalt mixture thin-layer overlay paving equipment is difficult to adjust the paving thickness, and the asphalt can often only be paved into a single thickness, with low flexibility in use, and the paving equipment is often equipped with only one set of auger, which makes it difficult to spread the asphalt evenly, and it is easy to spread the asphalt too thick or too thin, which directly affects the construction quality and causes waste of materials. However, the device only rolls the asphalt by the deadweight of the rolling roller, which may cause the asphalt to be loosely extruded, resulting in a low paving density. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a rolled asphalt mixture thin layer overlay paving equipment, which has the advantage of increasing the paving density and solves the problem that the device only rolls the asphalt through the deadweight of the rolling roller, which may cause the asphalt to be loosely squeezed and result in a low paving density.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a rolled asphalt mixture thin layer overlay paving equipment, comprising an outer shell, a first rotating shaft is rotatably connected to one side of the inner part of the outer shell, an eccentric wheel is fixedly connected to the outer wall of the first rotating shaft, two bearings are fixedly connected to the outer walls of the two bearings, and rolling rollers are fixedly connected to the outer walls of the two bearings, and a first driven wheel is fixedly connected to the outside of one end of the first rotating shaft that passes through the outer shell.

Since the eccentric wheel is fixedly connected to the first rotating shaft, when the first rotating shaft rotates, the eccentric wheel will generate eccentric movement inside the rolling roller, thereby causing the rolling roller to vibrate during rolling. This vibration not only helps to evenly distribute the asphalt mixture, but also enhances the rolling effect, ensures that the asphalt layer is more compact, and improves the quality and durability of the road surface. Through the arrangement of the fixed plate, the through hole, the positioning column, the push plate and the adjusting bolt, the position of the push plate can be easily adjusted by rotating the adjusting bolt. Since the push plate is fixedly connected to the positioning column and the positioning column slides in the through hole, the position of the push plate can be accurately adjusted, thereby adjusting the thickness of the asphalt before rolling.

[0009] Furthermore, a shovel plate is fixedly connected to one side of the fixed plate.

[0013] Furthermore, one end of the first rotating shaft away from the first driven wheel is fixedly connected to the first driving wheel.

[0014] Through the above scheme, the power device drives the first driven wheel to rotate, which will directly drive the first rotating shaft to rotate, and transmit power to the first driving wheel to rotate the first driving wheel, thereby reducing energy loss in the transmission process.

[0015] Furthermore, a connecting block is fixedly connected to one side of the shell.

[0016] Through the above solution, the connection block is used to connect the mobile device.

[0017] Furthermore, a motor is fixedly connected to one side of the top end of the housing, a second driving wheel is fixedly connected to the output end of the motor, and a first belt is fixedly connected to the outer wall of the second driving wheel and the first driven wheel.

[0018] Through the above solution, the motor is used as a power source, and directly drives the first rotating shaft and the first driven wheel thereon to rotate through the transmission of the second driving wheel and the first belt. This direct drive method reduces transmission loss and improves energy utilization efficiency.

[0019] Furthermore, a second belt is fixedly connected to the outside of the first driving wheel and the second driven wheel.

[0020] Through the above solution, the second belt is used as a transmission medium, and its elastic characteristics can buffer the speed fluctuation and impact load to a certain extent, making the transmission process smoother.

[0021] Furthermore, the eccentric wheel is rotatably arranged between the rolling rollers.

[0022] Through the above solution, the eccentric wheel will generate eccentric movement inside the rolling roller, thereby causing the rolling roller to vibrate during rolling.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The rolling type asphalt mixture thin layer overlay paving equipment, through the arrangement of the first rotating shaft, the eccentric wheel, the first driven wheel and the rolling roller, when the asphalt is extruded, the first driven wheel is driven to rotate by the power rotation, and the first driven wheel drives the first rotating shaft to rotate. Since the eccentric wheel is fixedly connected to the first rotating shaft, when the first rotating shaft rotates, the eccentric wheel will produce eccentric movement inside the rolling roller, thereby causing the rolling roller to vibrate during rolling. This vibration not only helps to evenly distribute the asphalt mixture, but also enhances the rolling effect, ensures that the asphalt layer is more compact, and improves the quality and durability of the road surface. Through the arrangement of the fixed plate, the through hole, the positioning column, the push plate and the adjusting bolt, the position of the push plate can be easily adjusted by rotating the adjusting bolt. Since the push plate is fixedly connected to the positioning column and the positioning column slides in the through hole, the position of the push plate can be accurately adjusted, thereby adjusting the thickness of the asphalt before rolling.

An adjusting bolt 11 is threadedly connected inside the fixing plate 7. The adjusting bolt 11 is used to adjust the position of the push plate 10, and the bottom end of the adjusting bolt 11 is rotatably connected to the push plate 10.

[0033] See also Figure 1 , Figure 2 and Figure 4A shovel plate 12 is fixedly connected to one side of the fixed plate 7, and the shovel plate 12 is used to clean the asphalt adhered to the outer wall of the rolling roller 5. A second rotating shaft 13 is rotatably connected to the inner side of the housing 1 at one end away from the first rotating shaft 2. A plurality of stirring blades 14 are fixedly connected to the outer wall of the second rotating shaft 13. A second driven wheel 15 is fixedly connected to the outer wall of one end of the second rotating shaft 13 that passes through the housing 1. The design of the stirring blades 14 helps to achieve uniform paving of the asphalt mixture during the paving process of the asphalt mixture. A first driving wheel 16 is fixedly connected to the end of the first rotating shaft 2 away from the first driven wheel 6. The first driven wheel 6 is driven to rotate by the power device, which will directly drive the first rotating shaft 2 to rotate, and transmit power to the first driving wheel 16, so that the first driving wheel 16 rotates, thereby reducing energy loss in the transmission process;

[0034] Among them, a connecting block 18 is fixedly connected to one side of the housing 1, and the connecting block 18 is used to connect the mobile device. A motor 19 is fixedly connected to one side of the top of the housing 1. The output end of the motor 19 is fixedly connected to the second driving wheel 20. The second driving wheel 20 and the outer wall of the first driven wheel 6 are fixedly connected to the first belt 17. The motor 19 serves as a power source, and directly drives the first rotating shaft 2 and the first driven wheel 6 thereon to rotate through the transmission of the second driving wheel 20 and the first belt 17. This direct drive method reduces transmission loss and improves energy utilization efficiency. The first driving wheel 16 and the second driven wheel 15 are fixedly connected to the outside with a second belt 21. The second belt 21 serves as a transmission medium. Its elastic characteristics can buffer speed fluctuations and impact loads to a certain extent, making the transmission process smoother. The eccentric wheel 3 is rotatably set between the rolling rollers 5. The eccentric wheel 3 will produce eccentric movement inside the rolling roller 5, thereby causing the rolling roller 5 to vibrate during rolling.

[0035] In this embodiment, the rolling type asphalt mixture thin layer overlay paving equipment, through the arrangement of the first rotating shaft 2, the eccentric wheel 3, the first driven wheel 6 and the rolling roller 5, when the asphalt is extruded, the first driven wheel 6 is driven to rotate by the power rotation, and the first driven wheel 6 drives the first rotating shaft 2 to rotate. Since the eccentric wheel 3 is fixedly connected to the first rotating shaft 2, when the first rotating shaft 2 rotates, the eccentric wheel 3 will produce eccentric movement inside the rolling roller 5, thereby causing the rolling roller 5 to vibrate during rolling. This vibration not only helps to evenly distribute the asphalt mixture, but also enhances the rolling effect, ensures that the asphalt layer is more compact, and improves the quality and durability of the road surface. Through the arrangement of the fixed plate 7, the through hole 8, the positioning column 9, the push plate 10 and the adjusting bolt 11, the position of the push plate 10 can be easily adjusted by rotating the adjusting bolt 11. Since the push plate 10 is fixedly connected to the positioning column 9, and the positioning column 9 slides in the through hole 8, the position of the push plate 10 can be accurately adjusted, thereby adjusting the thickness of the asphalt before rolling.

[0036] It should be noted that the rolling roller 5 has no power structure, and the rolling roller 5 is rotated only by pulling the device.

[0037] The working principle of the above embodiment is:

[0038] First, the operator connects the mobile device to the connecting block 18 to ensure that the equipment can move smoothly, and starts the motor 19. The motor 19 drives the second driving wheel 20 to rotate, drives the first driven wheel 6 to rotate through the second belt 21, and drives the first driving wheel 16 to rotate through the first rotating shaft 2. The first driving wheel 16 drives the second driven wheel 15 to rotate through the first belt 17, and then drives the second rotating shaft 13 to rotate. Since a plurality of stirring blades 14 are fixed on the second rotating shaft 13, the stirring blades 14 stir the asphalt mixture. During the movement of the equipment, the stirred asphalt mixture is evenly spread on the ground by the push plate 10, and the rolling roller 5 rolls to perform preliminary rolling of the asphalt. Since the eccentric wheel 3 is fixed on the first rotating shaft 2, when the first rotating shaft 2 rotates, the eccentric wheel 3 generates eccentric motion inside the rolling roller 5, causing the rolling roller 5 to vibrate during rolling. This vibration helps to evenly distribute the asphalt mixture and improve the rolling effect, ensuring that the asphalt layer is more compact. In order to keep the rolling roller 5 clean and work efficiently, the shovel plate 12 is set to clean the asphalt adhering to the outer wall of the rolling roller 5 during the rolling process.
