Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1

[0026] Please see Figure 1 - Figure 4 This application provides an asphalt pavement crack sealing machine, comprising:

[0027] An asphalt tank 101 is provided with a discharge pipe 102 on the right side of the asphalt tank 101. An asphalt nozzle 103 is connected to the lower right end of the discharge pipe 102. The asphalt tank 101 is installed on the top of the crack sealing machine frame 100.

[0028] A telescopic adjustment mechanism 200 is installed between the discharge pipe 102 and the asphalt nozzle 103. This mechanism allows for automatic telescopic and angle adjustment on uneven road surfaces without affecting the normal discharge of asphalt molten material. It changes the angle and height of the asphalt nozzle 103, preventing deformation or displacement even on rough surfaces, ensuring stable asphalt injection into cracks. The telescopic adjustment mechanism 200 includes mounting circular plates 201 respectively fitted onto the discharge pipe 102 and the asphalt nozzle 103. A metal telescopic pipe 203 is positioned between the two mounting circular plates 201. The metal telescopic pipe 203 connects to the discharge pipe 102 and the asphalt nozzle 103. 3. The internal structure is interconnected, facilitating the flow of asphalt molten material and withstanding its temperature. It also allows for easy angle adjustment when encountering rough road surfaces. The asphalt nozzle 103 is fitted with a lower pressure plate 202, which conforms to the road surface and flattens the asphalt used for grouting. The upper mounting circular plate 201 has a telescopic column 205 on its side. When encountering high points on the road surface, the telescopic column 205 can extend and retract to change its length. An angle adjustment component 206 is provided between the telescopic column 205 and the side of the lower pressure plate 202. When the lower pressure plate 202 encounters rough sections, it can be adjusted in conjunction with the angle adjustment component 206 to change the angle of the lower pressure plate 202, making it easier to overcome the rough sections and continue grouting.

[0029] In this embodiment, preferably, the telescopic column 205 includes a protrusion fixed to the side of the mounting circular plate 201. An inner rod 2053 is provided on the lower surface of the protrusion. An outer tube 2051 is sleeved on the inner rod 2053. The length between the two can be extended and retracted. A spring 2052 is sleeved on the outer tube 2051 and the inner rod 2053. The upper and lower ends of the spring 2052 are respectively fixed to the lower surface of the protrusion and the upper surface of the fixing plate 2061.

[0030] In this embodiment, preferably, the lower pressure plate 202 has a lug 204 on its side, and an angle adjustment component 206 is provided between the lug 204 and the outer tube 2051. The angle adjustment component 206 includes a fixing plate 2061 fixed to the lower end of the outer tube 2051. A lower fixing rod 2063 is provided on the upper surface of the lug 204. Multiple inclined tension springs can be provided circumferentially on the upper surface of the lug 204 and the lower surface of the fixing plate 2061. The inclined tension springs form a certain angle with the vertical direction, and the multiple inclined tension springs form an umbrella shape, so that the angle rotation of the lower fixing rod 2063 will return to its original position under the action of the inclined tension springs. This is not shown in this application, but can be set as needed in actual application. An adjusting ball 2064 is provided at the upper end of the lower fixing rod 2063, and a spherical sleeve 2062 is provided on the lower surface of the fixing plate 2061. The adjusting ball 2064 rotates and is located in the spherical sleeve 2062.

[0031] In this embodiment, preferably, both ends of the lower pressure plate 202 are provided with arc-shaped rocker plates 2021 with their outer ends curving upwards. The upward curving of the arc-shaped rocker plates 2021 facilitates movement along the rugged road surface.

[0032] In summary, as the crack sealing machine moves across the road surface, the asphalt nozzle 103 extends into the road cracks, and the lower pressure plate 202 adheres to the road surface. The asphalt nozzle 103 injects molten asphalt into the cracks. As the crack sealing machine moves, the lower pressure plate 202 flattens the molten asphalt. In other locations, the outer end of the curved rocker 2021 is sufficiently far from the ground, allowing it to easily move along uneven surfaces. The unevenness and protrusions cause a certain angle change between the curved rocker 2021 and the lower pressure plate 202. The lower fixed rod 2063 and the adjusting ball 2064 rotate in the spherical sleeve 2062 to adapt to the position of the uneven protrusion. When the ground protrudes, the outer tube 2051 moves along the inner rod 2053, and the spring 2052 is compressed. After passing the ground protrusion, the spring 2052 can drive the asphalt nozzle 103 to return to its original position downward. This flexible elastic adjustment will not cause the asphalt nozzle 103 and the discharge pipe 102 to deform or be damaged due to impact, thus realizing the stable filling of road cracks by the crack sealing machine.

[0033] Example 2

[0034] Reference Figure 5 and Figure 6 This is the second embodiment of the present utility model.

[0035] In this embodiment, preferably, a scraper component 300 is provided inside the asphalt tank 101. Using the scraper component 300, the asphalt molten material remaining on the inner wall of the asphalt tank 101 can be scraped downwards and collected at the bottom, facilitating the full discharge of the asphalt molten material. Compared to subsequent cleaning, this reduces the hassle of cleaning and minimizes asphalt molten material waste. The operation is simple and cleaning is convenient. The scraper component 300 includes two scraper frames 301 symmetrically installed inside the asphalt tank 101. The scraper frames 301 can be U-shaped, and an elastic scraper plate 305 is provided at the free end of each scraper frame 301. The elastic scraper plate 305 is made of high-temperature resistant silicone and is not affected by the temperature of the asphalt molten material. Simultaneously, the free ends of the elastic scraper plates 305 at the ends of the two scraper frames 301 are in contact, so even if a shaft or rod is provided on the inner wall of the asphalt tank 101, the elasticity of the elastic scraper plate 305 will change. The elastic scraper 305, which slightly exceeds the axis, returns to its original position and aligns again, allowing the elastic scraper 305 and scraper frame 301 to fully contact the inner wall of the asphalt tank 101, increasing the scraping area and range of the asphalt melt. The scraper frame 301 is equipped with a lifting rod 302 that penetrates the top of the asphalt tank 101 and protrudes to the outside. The inner surface of the scraper frame 301 is equipped with an inner fixing seat 306 that connects to the lower surface of the lifting rod 302. A connecting plate 303 is provided between the upper ends of the two lifting rods 302, which facilitates the synchronous movement of the two lifting rods 302 by pressing the connecting plate 303. A conical scraper cylinder 304 is provided on the inner surface of the upper end of the asphalt tank 101, which is sleeved on the lifting rod 302. The lower tip of the conical scraper cylinder 304 is in contact with the surface of the lifting rod 302, so that the asphalt adhering to its surface can be scraped off when the lifting rod 302 moves upward.

[0036] In summary, when scraping the asphalt melt is not required, the scraper frame 301 is located inside the asphalt tank 101 near the upper end. Holding the connecting plate 303 and moving it downwards causes the two lifting rods 302 and the scraper frame 301 to move downwards. The outer surfaces of the scraper frame 301 and the elastic scraper plate 305 contact the inner surface of the asphalt tank 101. When it moves to the shaft set on the inner wall of the asphalt tank 101, the shaft is used to install the U-shaped frame for mixing the asphalt melt. The elastic scraper plate 305 is restricted by the shaft and will deform and bend slightly below the shaft to move downwards. Without the restriction of the shaft, the elastic scraper plate 305 regains its elasticity, and the opposite elastic scraper plates 305 align and continue to contact the inner wall of the asphalt tank 101. As the scraper frame 301 continues to move downwards, it pushes the asphalt melt on the inner wall of the asphalt tank 101 downwards and gathers it, making it easy to suck out.

[0037] Example 3

[0038] This embodiment is obtained by combining Embodiment 1 and Embodiment 2.

[0039] During the process of moving and injecting asphalt molten material, the asphalt nozzle 103 is made flexible by using the telescopic adjustment mechanism 200. Even on rough roads, it can extend and retract to change the angle, and will not directly hit the rough road surface to cause deformation and damage. This increases the stability and safety of the crack sealing machine. In addition, as the asphalt molten material gradually decreases, the scraper component 300 can be used to scrape off the asphalt remaining on the inner wall of the asphalt tank 101.

[0040] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
