[0031] In combination Figures 1 to 6 As shown in the utility model, a kind of asphalt dispersion paving device for highway construction is provided, which includes rotating shaft 1 and scraper 2.
[0032] In combination Figures 1 to 6 As shown in the utility model, the rotating shaft 1 is vertically arranged, and the scraper connecting rod 11 is uniformly distributed around the rotating shaft 1. The scraper connecting rod 11 is horizontally placed, and one end of the scraper connecting rod 11 is fixedly connected to the cylindrical surface of the rotating shaft 1. The rotating shaft 1 drives the scraper connecting rod 11 to rotate clockwise. The scraper 2 includes inner blocking scraper 21 and outer blocking scraper 22. The inner blocking scraper 21 is fixedly connected to the scraper connecting rod 11 in a clockwise direction. The outer blocking scraper 22 is fixedly connected to the scraper connecting rod 11 in a counterclockwise direction. The outer blocking scraper 22 is closer to the rotating shaft 1 than the inner blocking scraper 21.
[0033] In this embodiment, the inner blocking scraper 21 and the outer blocking scraper 22 with different inclination directions control the horizontal movement of excess asphalt during the process of scraping asphalt, helping the excess asphalt to better fill the position lacking asphalt. The rotating shaft 1 can drive the scraper 2 to move, repeatedly moving the excess asphalt horizontally through the inner blocking scraper 21 and the outer blocking scraper 22. The scraper 2 driven by the rotating shaft 1 can quickly and repeatedly perform the scraping action, achieving better paving effect.
[0034] In actual use, the utility model device is usually mounted on an engineering vehicle. The inner blocking scraper 21 and the outer blocking scraper 22 can control the position of excess asphalt by tilting, but the rolling track of excess asphalt is in a snake shape during single scraping, and some positions are not covered by the track. The driving mode of the rotating shaft 1 can complete the multiple scraping actions at the same position without affecting the normal forward movement of the engineering vehicle, improve the coverage rate of the rolling track, and ensure the paving effect.
[0035] In some embodiments, in combination with Figure 2 As shown, the number of scraper connecting rods 11 on the rotating shaft 1 is even, and each of the inner and outer barrier scrapers 21 and 22 is separately fixedly installed on a scraper connecting rod 11. In this connection mode, the independence between the inner and outer barrier scrapers 21 and 22 is stronger, and it is more convenient to observe the working state of each of the inner and outer barrier scrapers 21 and 22.
[0036] In some embodiments, in combination with Figure 1 As shown, the inner and outer barrier scrapers 21 and 22 are fixedly installed on each of the scraper connecting rods 11, and are distributed on both sides of the scraper connecting rod 11. The inner and outer barrier scrapers 21 and 22 are fixedly connected to the scraper connecting rod 11 at the end points. This connection mode is more compact, and the distribution density of the inner and outer barrier scrapers 21 and 22 is obviously increased compared with the previous connection mode, so that the movement of the excess part of the asphalt is more frequent, and the paving effect is increased.
[0037] In some embodiments, in combination with Figure 3 As shown, one of the inner barrier scrapers 21 and one of the outer barrier scrapers 22 form a group, and the inner and outer barrier scrapers 21 and 22 are distributed in groups along the scraper connecting rod 11. In this way, the coverage range of the scraper 2 is extended without increasing the volume of the individual inner and outer barrier scrapers 21 and 22, and the paving efficiency is increased.
[0038] In some embodiments, in combination with Figure 3 As shown, the total projection length of one of the inner barrier scrapers 21 and one of the outer barrier scrapers 22 on the scraper connecting rod 11 is an interval distance, and the translation distance between the groups of the inner and outer barrier scrapers 21 and 22 does not exceed an interval distance. The control interval distance can ensure that the scraping coverage between adjacent inner and outer barrier scrapers 21 and 22 can be connected, and the paving effect is ensured.
[0039] In some embodiments, in combination with Figure 4 As shown, the rotating shaft 1 drives the scraper connecting rod 11 to rotate counterclockwise, the inner barrier scraper 21 is fixedly connected to the scraper connecting rod 11 at an angle in the counterclockwise direction, and the outer barrier scraper 22 is fixedly connected to the scraper connecting rod 11 at an angle in the clockwise direction. There is a necessary correlation between the inclination direction of the inner and outer barrier scrapers 21 and 22 and the rotation direction of the rotating shaft 1. In combination with the case where the rotating shaft 1 rotates clockwise, the inclination direction of the scraper 2 corresponding to different rotation conditions of the rotating shaft 1 is described.
[0040] In some embodiments, in combination with Figure 5As shown, the inner blocking scraper 21 and the outer blocking scraper 22 are both long plates with rectangular cross sections, and the inner blocking scraper 21 and the outer blocking scraper 22 are inclined in the vertical direction, and the inner blocking scraper 21 and the outer blocking scraper 22 are inclined upward on the side toward the rotating advancing direction, the upwardly inclined bottom surface can exert a certain downward pressure on the asphalt, which is conducive to achieving a better leveling effect, and the inclination of the advancing surface can reduce the hindering effect of the excess asphalt on the advancement of the scraper 2.
[0041] In some embodiments, in combination with Figure 6 As shown, the inner blocking scraper 21 and the outer blocking scraper 22 are both long plates with triangular cross sections, and the side corresponding to the base of the cross-sectional triangle on the inner blocking scraper 21 and the outer blocking scraper 22 is away from the rotating advancing direction of the scraper 2, and the scraper 2 with this structure has basically the same effect as the case of the rectangular cross section described above on the surface of the asphalt, and it is two ways to achieve the same effect.
[0042] In some embodiments, in combination with Figure 4 As shown, the asphalt dispersing and leveling device for highway construction further comprises an outer baffle 3, the outer baffle 3 is in the form of a circular ring and is sleeved on the rotating shaft 1, the other end of the scraper connecting rod 11 is fixedly connected to the inner wall of the outer baffle 3, and the end of the inner blocking scraper 21 away from the rotating shaft 1 is attached to the inner wall of the outer baffle 3, so that the excess asphalt can be prevented from leaving the coverage area of the scraper 2 in the case of a large amount of excess asphalt, and the effect of the scraper 2 on controlling the position of the asphalt is ensured.
[0043] In some embodiments, in combination with Figure 4 As shown, the end of the outer blocking scraper 22 close to the rotating shaft 1 is attached to the outer wall of the rotating shaft 1, which can avoid dead angles in the center of the coverage area of the scraper 2 and ensure the leveling effect.
[0044] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
