Early common distresses include cracks, potholes, ruts, loosening, subsidence, slab slab slab slab slab slab slabs, and surface damage. Currently, pothole treatment typically involves workers manually cleaning the dust and stones from the pothole, then pouring in a mixture of asphalt and stones, and finally compacting it.

[0015] Figure 2 This is a bottom view of the present invention;

[0017] Figure 4 This is a cross-sectional view of the sliding sleeve of this utility model. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1 to 4As shown, a maintenance device for asphalt concrete pavement includes a diesel engine 1, a drive seat 2 at the bottom of the diesel engine 1, a drive wheel 3 connected to the drive shaft of the diesel engine 1 inside the drive seat 2, a drive unit detachably connected to the drive seat 2 by bolts, a push wheel assembly 8 fixedly connected to the left side of the drive unit, a longitudinally arranged sweeping assembly 13 being driven on the drive unit, a cleaning assembly 12 at the bottom of the drive unit, and the cleaning assembly 12 moving up and down on the drive unit via a lifting device 14.

[0020] When using this device, the pusher assembly 8 is placed on the ground to form a fulcrum, allowing it to move back and forth. When it is necessary to clean the damaged areas inside the asphalt, the handle is pressed down, and the adjuster 5 is adjusted so that the telescopic device 14 is at its lowest position from the right end. This ensures that the cleaning component 12 is in contact with the ground. It should be noted that the diesel engine 1 is located directly above the pusher assembly 8, which makes the weight distribution more reasonable and facilitates the operator's road cleaning operation. In addition, when the cleaning component 12 vibrates with the ground, it keeps the entire device in a stable state, preventing the pusher assembly 8 from jumping. After completing the first cleaning step, the telescopic device 14 is at its highest position from the right end. At this time, the cleaning component 12 is at a certain distance from the ground. The sweeping component 13 then treats the worn road surface, thoroughly removing the fine stones and gravel inside. In this way, during the repair process, the asphalt concrete can come into contact with the old asphalt in a clean environment, resulting in a better compaction effect and longer service life, and preventing internal debris from affecting asphalt caking.

[0021] Two handles are fixedly connected to the top right side of the drive seat 2. One handle is equipped with a gearbox 4, and the other handle is equipped with an adjuster 5. The adjuster 5 is electrically connected to the telescopic device 14.

[0022] The transmission 4 can adjust the meshing state of the internal teeth of the transmission 6. The drive unit includes the transmission 6, and the transmission 6 has a mounting part 10. The driven pulley of the transmission 6 is connected to the drive wheel 3 via a belt.

[0023] This technology uses the same speed control principle as existing hand-held tractors, so it will not be elaborated upon.

[0024] The cleaning assembly 13 includes a drive shaft 7, on which a plurality of cleaning brushes 9 are provided. Each cleaning brush includes a metal part, and the tail end of the metal part is fixedly connected to the cleaning brush.

[0025] A worm gear 11 is provided below the drive shaft on the gearbox 6 and at the cleaning assembly 13. The cleaning assembly 13 also includes a worm wheel housing 131. A worm wheel component 132 is rotatably connected inside the worm wheel housing 131. The worm wheel component 132 meshes with the worm gear 11. A clamping disc 134 is provided on the worm wheel component 132. A shaft component 133 is provided through the clamping disc 134.

[0026] When the bottom of the lifting device 14 is at its highest point, the worm gear 11 drives the sweeping brush to rotate, which cleans up the broken stones on the road surface.

[0027] Lifting device 14 at the bottom of worm gear 11;

[0028] In one embodiment, the cleaning component 12 includes a drive disk 121 disposed at the bottom of the lifting device 14, a scraper assembly 123 disposed at the bottom of the drive disk 121, the scraper assembly 123 being comma-shaped and having a tooth 124 at one end, and a grinding blade 122 disposed on the outer wall of the drive disk 121.

[0029] When implementing this embodiment, when the drive disc 121 rotates and comes into contact with the ground, the drive disc 121 can contact the damaged road surface and grind the asphalt in the damaged road surface. After the tip of the comma-shaped scraper group 123 comes into contact with the ground, it quickly breaks up the debris on the ground. This can completely remove the asphalt from the damaged road surface. In addition, the grinding blade 122 can repair the cut of the undamaged asphalt surface, making it smoother. This is beneficial for the continuous contact gap after the asphalt is laid, and it will not cause cracks.

[0030] When the drive disc 121 moves up and down, the lifting device 14 includes a telescopic device 141. A bevel gear 145 is fixedly connected to the bottom end of the worm 11. A collar is provided at the free end of the telescopic device 141. The inner wall of the collar is in contact with the worm 11 through a sliding plug ring 142. A sliding sleeve 143 is provided on the inner wall of the collar at the free end of the telescopic device 141 and is rotatably connected to the sliding sleeve 146. An inner bevel gear ring 144 is fixedly connected to the inner wall of the sliding sleeve 146.

[0031] The telescopic device 141 drives the sliding sleeve 146 to move downward. At this time, the inner bevel gear ring 144 on the sliding sleeve 146 moves downward. When the inner bevel gear ring 144 moves to the position of the bevel gear 145, the bevel gear 145 meshes with the inner bevel gear ring 144. At this time, the inner bevel gear ring 144 is driven to rotate by the bevel gear 145, thereby adjusting the height of the drive disc 121 to achieve crushing. It should also be noted that the height can be adjusted by pressing down the handle according to the depth of the damaged surface.

[0032] This integrated crushing and cleaning method features a continuous operation process, allowing a single person to complete the cleaning operation, saving time and effort, and reducing the cost of road repair.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
