At the same time, the striking head is driven by the connecting strip to hit the side wall of the collecting frame, thereby causing the collecting frame to vibrate, thereby promoting the falling discharge of the melted asphalt on the inclined surface and improving the utilization efficiency.

DETAILED DESCRIPTION

[0027] Example, refer to Figures 1-6 A highway asphalt pavement maintenance device includes a base plate 1 and a storage box 3. A driving wheel 9 is provided at the lower end of the base plate 1. The storage box 3 is connected to a feeding pipe 2 and a motor 4. A rolling roller 6 and a collecting frame 7 are provided at the lower end of the base plate 1. A knocking assembly 12, a rotating plate 11 and a discharge pipe 10 are provided below the base plate 1. A movable cylinder 17, a telescopic spring 18 and a retracting plate 19 are provided above the rolling roller 6.

[0028] Furthermore, the storage box 3 is fixedly connected to the upper side wall of the bottom plate 1, the side wall of the storage box 3 is fixedly connected to the feeding pipe 2, the upper end of the storage box 3 is fixedly connected to the motor 4, and the storage box 3 is fixedly connected to the discharge pipe 10; the storage box 3 is provided with a rotating shaft 15 inside, and the outer wall of the rotating shaft 15 is fixedly connected to a number of stirring rods 14 distributed in a circumferential array, the upper end of the rotating shaft 15 is fixedly connected to the motor 4, and the lower end of the rotating shaft 15 vertically penetrates the storage box 3 and the side wall of the bottom plate 1 and is fixedly connected to the rotating plate 11, the rotating plate 11 is elliptical, and the outer wall of the rotating plate 11 is fixedly connected to the magnetic block 2 16; the lower side wall of the bottom plate 1 is fixedly connected to the fixed seat 5, the fixed seat 5 is rotatably connected to the rolling roller 6, and the side wall of the fixed seat 5 is fixedly connected to the support plate 13, which supports The plate 13 is set in an "L" shape, the support plate 13 is fixedly connected to the side wall of the collecting frame 7, and the collecting frame 7 is located on one side of the rolling roller 6; the side wall of the collecting frame 7 close to the rolling roller 6 is fixedly connected with a scraper 20, and the side wall of the collecting frame 7 away from the rolling roller 6 is provided with a discharge hole 8, and a cavity 22 is provided inside the collecting frame 7, and an electric heating rod 21 is provided inside the cavity 22; the telescopic spring 21 is located on the inner side of the movable cylinder 17, one end of the movable cylinder 17 is fixedly connected to the side wall of the bottom plate 1, the inner wall of the movable cylinder 17 is slidably connected to the outer wall of the contraction plate 19, and the contraction plate 19 is set in a "T" shape, and the two ends of the telescopic spring 28 are respectively fixedly connected to the side wall of the bottom plate 1 and the side wall of the contraction plate 19, and the contraction plate 19 is located directly above the rolling roller 6.

[0029] It should be noted that asphalt can be added to the interior of the storage box 3 through the feeding pipe 2, and a heating device can be set inside the storage box 3, and the motor 4 can be used to drive the rotation of the rotating shaft 15 and the stirring rod 14 to ensure that the asphalt is in a melted state. When maintaining the road surface, the base plate 1 can be pushed manually, or a driving device can be installed on the driving wheel 9 to drive the driving wheel 9 to rotate, so as to pave the road surface in different areas. In the process of paving asphalt to maintain the road surface, the valve on the discharge pipe 10 can be opened to discharge the asphalt onto the road surface. As the base plate 1 moves, the rolling roller 6 is driven to rotate. During the travel of the base plate 1, the piled-up asphalt is flattened by the rolling roller 6, thereby completing the maintenance of the potholes. When asphalt or impurities are attached to the surface of the rolling roller 6, as it rotates, it can drive the surface protrusions to rotate synchronously, thereby squeezing the contraction plate 19 and making the telescopic spring The second spring 18 contracts. After the protrusion separates from the retraction plate 19, the elastic recovery of the telescopic spring 218 allows the retraction plate 19 to impact the surface of the rolling roller 6, thereby causing vibration, thereby loosening the attachments on the surface of the rolling roller 6, thereby providing effective assistance for subsequent cleaning work. During the rotation of the rolling roller 6, the surface of the rolling roller 6 contacts the scraper 20. When there are protrusions on the surface of the rolling roller 6, they are scraped off by the scraper 20. At the same time, the centrifugal force generated by the rotation of the rolling roller 6 causes the attachments to quickly slide into the inside of the collecting frame 7, thereby completing the cleaning of the surface of the rolling roller 6, ensuring the quality of the rolling, and improving the flatness of the road surface. After the asphalt attachments enter the collecting frame 7, they can be melted by the work of the electric heating rod 21, and at the same time, in conjunction with the inclination angle of the bottom wall of the collecting frame 7, they can be discharged back onto the road surface through the discharge hole 8, thereby improving the utilization effect and reducing waste.

[0030] Reference Figure 2 、 Figure 3 and Figure 6 , further; the knocking assembly 12 includes a telescopic spring 123, a fixed block 124 and a movable rod 125, the movable rod 125 is arranged in a "T" shape, one end of the movable rod 125 passes through the side wall of the fixed block 124, and the fixed block 124 is fixedly connected to the lower side wall of the base plate 1; one end of the movable rod 125 is fixedly connected to a baffle 122, and the side wall of the baffle 122 away from the movable rod 125 is provided with a magnetic block 121, the other end of the movable rod 125 is fixedly connected to a number of connecting strips 126 distributed in a linear array, and one end of the connecting strip 126 is fixedly connected to a knocking head 127; the telescopic spring 123 is sleeved on the outer wall of one end of the movable rod 125, and the two ends of the telescopic spring 123 are respectively fixedly connected to the side wall of the fixed block 124 and the side wall of the baffle 122.

[0031] It should be noted that: the end of magnet block 121 away from the baffle 122 and the end of magnet block 2 16 close to the baffle 122 have the same polarity. Therefore, in the process of the rotating shaft 15 driving the rotating plate 11 to rotate, when magnet block 2 16 approaches magnet block 121, the mutual repulsion of magnets drives the baffle 122 to squeeze the telescopic spring 123, and drives the movable rod 125 to move toward the side of the rolling roller 6. At the same time, the connecting bar 126 drives the knocking head 127 to hit the side wall of the collecting frame 7, thereby causing the collecting frame 7 to vibrate, thereby promoting the falling and discharge of the melted asphalt on the inclined surface and improving the utilization efficiency. When magnet block 2 16 is away from magnet block 121, the elastic recovery of the telescopic spring 123 drives the movable rod 125 and the knocking head 127 to reset, thereby ensuring the falling speed of the melted asphalt through reciprocating vibration.

[0032] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
