Description

Technical Field

[0001] This utility model relates to the technical field of asphalt spraying vehicles, specifically an emulsified asphalt spraying vehicle with tire anti-sticking features. Background Technology

[0002] Emulsified asphalt, as a core material in road construction and maintenance projects, is widely used in asphalt pavement processes such as slurry seal, prime coat, tack coat, and micro-surfacing due to its advantages such as convenient construction, energy saving and environmental protection, and excellent low-temperature performance. During the construction process, emulsified asphalt spraying trucks are needed to spray emulsified asphalt onto the road surface.

[0003] During the operation of an asphalt spraying truck, because the spraying arm is installed between the two tires, as the vehicle moves, uncured asphalt material sticks to the tires during asphalt spraying. With continued movement, more and more asphalt adheres, affecting the normal driving of subsequent vehicles. Furthermore, the large amount of asphalt stuck to the tires causes uneven tire height, resulting in significant shaking during vehicle operation, hindering the laying of subsequent asphalt and increasing the risk of tire blowouts.

[0004] Therefore, we propose an emulsified asphalt spraying truck with tire anti-sticking technology to solve the above problems. Utility Model Content

[0025] 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.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the asphalt spraying truck includes a frame body 1 and a wheel 2 installed on one side of the bottom of the frame body 1. When the asphalt spraying truck is in motion, the wheel 2 installed on one side of the bottom of the frame body 1 moves clockwise toward the first scraper 6.

[0028] A bolt groove 3 is provided on one side of the bottom of the frame body 1. The bolt grooves 3 are evenly distributed on both sides of the bottom of the frame body 1, and the inner diameter of the bolt groove 3 is adapted to the outer diameter of the positioning bolt 8. A scraper frame 4 is distributed on one side of the wheel 2, and a diverter seat 5 is fixed at the bottom of the inner cavity of the scraper frame 4. The diverter seat 5 is generally conical, and the two sides of the diverter seat 5 are provided with arc-shaped surfaces. A first scraper 6 is fixed on one side of the top of the scraper frame 4. The side of the first scraper 6 near the wheel 2 is conical, and the first scraper 6 is generally arc-shaped. The first scraper 6 is embedded in one side of the top of the scraper frame 4, and the top of the scraper frame 4 is far away from the first wheel 2. A connecting member 7 is fixedly provided on one side of the scraper 6, and a positioning bolt 8 passes through one side of the top of the connecting member 7. The positioning bolt 8 extends above the top of the connecting member 7. A fixed shaft 9 is fixedly provided on one end surface of the scraper frame 4, and a side scraper plate 10 is connected to the other end of the fixed shaft 9. A torsion spring 11 is sleeved on the outer ring surface of one end of the fixed shaft 9. The two ends of the torsion spring 11 are respectively connected to one end surface of the fixed shaft 9 and one end side wall of the side scraper plate 10. A second scraper 12 is fixedly provided on the side of the side scraper plate 10 away from the fixed shaft 9 and close to the wheel 2, and an inclined surface 13 is distributed on one side of the second scraper 12.

[0029] During use, the position of the connector 7 is pre-adjusted so that it drives the scraper frame 4 to move laterally, allowing the scraper frame 4 to better match the wheel 2. After the position of the connector 7 is adjusted, the positioning bolt 8 is inserted through one end of the top of the connector 7, and one end of the positioning bolt 8 is inserted into the inside of the bolt groove 3. Then, the positioning bolt 8 is tightened so that it extends into the inside of the bolt groove 3, thereby achieving the positioning of the connector 7. This facilitates the subsequent maintenance of a suitable distance between the scraper frame 4 and the first scraper 6 and the wheel 2. During operation, when a large amount of asphalt adheres to the surface of the rear wheel 2 while the vehicle is driving, the wheel 2 will... The asphalt impurities adhering to the surface of the wheel 2 are moved towards the first scraper 6, which then scrapes away the asphalt impurities. Because the first scraper 6 is arc-shaped, some of the scraped asphalt impurities fall along its arc surface into the inner side of the scraper frame 4 and move along the diversion seat 5 inside the scraper frame 4. The arc surfaces on both sides of the top of the diversion seat 5 divert the asphalt impurities, which are then discharged through openings on both sides of the scraper frame 4. Simultaneously, side scraper plates 10 are symmetrically arranged on both sides of the scraper frame 4, and a second scraper 12 is installed at one end of each side scraper plate 10. Positioned against the side of the wheel 2, the second scraper 12 removes some of the asphalt impurities that adhered to the side wall of the wheel 2 after being scraped by the first scraper 6 during the rotation of the wheel 2. Since the second scraper 12 has an inclined surface 13 on one side, the scraped asphalt impurities move along the inclined surface 13, preventing them from re-adhering to the side of the wheel 2. It is worth noting that because one end of the side scraper 10 is rotatably connected to the fixed shaft 9, and a torsion spring 11 is fitted on the outer ring of the fixed shaft 9, when the side scraper 10 scrapes away asphalt impurities with high hardness and adhesion through the second scraper 12, the force will cause the side scraper 10 to... The side scraper 10 causes the torsion spring 11 to deform accordingly. At this time, the side scraper 10 drives the second scraper 12 to adjust the tilt. However, since the angle that the side scraper 10 can move is within 30 degrees, the movement of the side scraper 10 will ensure that the second scraper 12 can always cover the side wall of the wheel 2. Under the reverse force generated by the deformation of the torsion spring 11, when the force applied to the second scraper 12 disappears, the torsion spring 11 will drive the side scraper 10 to reset, which will facilitate the subsequent reset of the second scraper 12. This will better remove the asphalt impurities attached to the side wall of the wheel 2, and the reverse force generated by the deformation of the torsion spring 11 can also provide a simple buffering effect.

[0030] like Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, a groove 14 is provided on the inner sidewall of the top of the scraper frame 4, and a positioning hole 15 is connected to one side of the groove 14. The positioning holes 15 are equidistantly distributed along one side of the top of the scraper frame 4, and the positioning holes 15 and the scraper frame 4 form an integrated structure. A slider 16 is engaged inside the groove 14, and a push rod 17 is rotatably connected to one side of the slider 16. The two ends of the push rod 17 are rotatably connected to the slider 16 and the baffle 18 respectively through a rotating seat. The other end of the push rod 17 is connected to the baffle 18, and a connecting ear 19 is fixed in the middle of the top of the baffle 18. An arc-shaped surface is provided at the bottom of the end of the baffle 18 away from the push rod 17, and the top of the baffle 18 is rotatably connected to the support rod 20 through the connecting ear 19. The support rod 20 is connected to one side of the top of the connecting ear 19.

[0031] During use, since the slider 16 is engaged with the groove 14, when the slider 16 is subjected to force, it will slide inside the groove 14. As the slider 16 slides, it will drive the push rod 17 to move accordingly. At this time, the push rod 17 pushes the baffle 18 connected to its other end. The baffle 18 rotates along one end of the support rod 20 through the connecting ear 19 fixed at its top, which facilitates the subsequent adjustment of the inclination of the baffle 18. This prevents asphalt impurities from splashing when scraping the surface of the wheel 2. After the adjustment is completed, the slider 16 moves to the appropriate position and stops moving. With the help of the positioning hole 15, the positioning of the slider 16 can be easily achieved.

[0032] like Figure 5 As shown, in some embodiments, a return spring 21 is provided on the inner side of one end of the slider 16, and a positioning rod 22 is connected to the other end of the return spring 21. The positioning rod 22 is slidably connected to the slider 16 through the return spring 21, and the outer diameter of the positioning rod 22 is adapted to the inner diameter of the positioning hole 15. A detachable end cap is provided on the surface of one end of the slider 16 for subsequent replacement of the return spring 21. An auxiliary sliding plate 23 is sleeved on the outer ring surface of one end of the positioning rod 22.

[0033] In use, when the slider 16 slides along the groove 14 to the appropriate position, the positioning rod 22 moves to one side of the positioning hole 15. At this time, the pressure applied to the return spring 21 disappears. Since the return spring 21 deforms when it is pressed, it generates a reverse force. Therefore, when the pressure applied to the return spring 21 disappears, the reverse force generated by the deformation of the return spring 21 will push the positioning rod 22 in the opposite direction. This facilitates the subsequent insertion of one end of the positioning rod 22 into the inner side of the positioning hole 15 to achieve the positioning of the slider 16. The auxiliary slide plate 23 is provided to improve the stability of the positioning rod 22 during its movement.

[0034] like Figure 1 and Figure 2As shown, in some embodiments, a storage box 24 is provided at the top of the frame body 1, and an asphalt spraying mechanism 25 is connected to the bottom side of the storage box 24. The asphalt spraying mechanism 25 includes a pump, a pump pipe and a nozzle, etc., which facilitates the subsequent spraying of asphalt onto the road surface.

[0035] When in use, the asphalt material stored in the storage box 24 can be extracted by the asphalt spraying mechanism 25 and sprayed out by the nozzle to achieve asphalt spraying treatment on the road surface.

[0036] In summary, during use, slide the slider 16 in advance to a suitable position inside the groove 14. Then, the reverse force generated by the deformation of the return spring 21 pushes the positioning rod 22, inserting one end into the inner side of the positioning hole 15 to position the slider 16. It is worth noting that when the slider 16 moves, the push rod 17 pushes the baffle 18, causing the baffle 18 to move along the support rod 20 through the connecting ear 19. This allows the baffle 18 to be adjusted to a suitable inclination, effectively preventing asphalt impurities from splashing when scraping off asphalt impurities adhering to the surface of the wheel 2. Then, the connecting piece 7 drives the scraper frame 4 to move, allowing the scraper frame 4 to better fit the wheel 2. After adjustment, insert one end of the positioning bolt 8 into the inner side of the bolt groove 3, and then tighten the positioning bolt 8 to position the connecting piece 7. This ensures that the scraper frame 4 and the first scraper 6 maintain a suitable distance from the wheel 2. During operation, when a large amount of asphalt adheres to the rear of the vehicle while it is in motion... When the wheel 2 rotates clockwise, the asphalt impurities attached to its surface move towards the first scraper 6. The first scraper 6 then scrapes off the asphalt impurities. Some of the scraped-off asphalt impurities fall along the arc surface of the first scraper 6 into the inner side of the scraper frame 4, where they are diverted by the diverter seat 5. After diversion, the asphalt impurities are discharged through the openings on both sides of the scraper frame 4. At the same time, since the scraper frame 4 is symmetrically provided with side scraper plates 10 on both sides, and the second scraper 12 at one end of the side scraper plate 10 is attached to the side of the wheel 2, during the rotation of the wheel 2, some of the asphalt impurities that have been scraped off by the first scraper 6 and are attached to the side wall of the wheel 2 will be scraped off by the second scraper 12. Since the second scraper 12 has an inclined surface 13 on one side, the scraped-off asphalt impurities will move along the inclined surface 13 to prevent the scraped-off asphalt impurities from re-adhering to the side of the wheel 2.

Although the 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.
