Description

Technical Field

[0001] The utility model relates to the field of road asphalt leveling, in particular to a road asphalt leveling device. Background Art

[0002] After the road excavation construction is completed, it needs to be restored. During the restoration, a concrete roadbed needs to be poured and a layer of asphalt needs to be spread on the concrete roadbed. When spreading the asphalt, the transport vehicle pours the high-temperature asphalt on the concrete roadbed of the road surface, and uses the excavator bucket to level the asphalt. After spreading, a roller is used to flatten it. However, when using the excavator bucket for leveling, the width of the bucket cannot match the width of the road surface, and multiple leveling and paving are required. In addition, the bucket leveling height is different, which results in poor leveling quality and affects road traffic. Utility Model Content

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0019] like Figure 1 As shown, a road asphalt leveling device includes a leveling scraper 1. A plurality of clamping blocks 2 are arranged in the center of the leveling scraper 1. A clamping groove 3 matching the bucket 16 of the excavator 15 is opened on the clamping block 2. The shape of the clamping groove 3 matches the front end surface of the bucket 16, so that the bucket 16 can be clamped and pushed with the leveling scraper 1. Sliding and adjustable L-shaped guide plates 5 are arranged on both sides of the leveling scraper 1. A spray assembly for cooling the L-shaped guide plate 5 is arranged inside.

[0020] like Figure 2 As shown, a T-shaped slider 8 slidably connected to the sliding groove 4 is fixed to the front end face of the L-shaped guide plate 5. The T-shaped slider 8 can move along the sliding groove 4 to achieve adaptive adjustment of the width of the road surface 13, and the T-shaped slider 8 can also prevent the L-shaped guide plate 5 from falling off. A plurality of positioning screws 9 for fixing to the side of the leveling scraper 1 are threadedly connected to the T-shaped slider 8.

[0021] like Figure 1 As shown, two sliding grooves 4 are arranged at the side ends of the leveling scraper 1 and are located on the outer side of the clamping block 2.

[0022] like Figure 1As shown, the outer end of the L-shaped material guide plate 5 is fixed with an outwardly inclined receiving plate 6, which can increase the receiving width to prevent materials from leaking to the outside of the L-shaped material guide plate 5, and the bottom of the L-shaped material guide plate 5 is fixed with a bottom plate 7 extending to the receiving plate 6.

[0023] like Figure 1 As shown, the spray assembly includes a cooling water tank 10, which is placed on the upper part of the bottom plate 7 and has a plurality of cooling holes on one side thereof facing the L-shaped material guide plate 5.

[0024] like Figure 1 As shown, a limiting plate 11 is provided outside the cooling water tank 10 to limit the cooling water tank 10 , one end of the limiting plate 11 is fixed to the receiving plate 6 , and the other end of the limiting plate 11 is fixed to the L-shaped material guide plate 5 .

[0025] The leveling scraper 1 is provided with two strap holes 12, which are used for binding the movable straps.

[0026] The implementation principle of a road asphalt leveling device in the embodiment of the present application is:

[0027] When the excavated road surface 13 is leveled with asphalt, firstly, a dump truck is used to pour the hot asphalt into the road surface 13, and the bucket of the excavator 15 is used to lift the straps on the upper part of the strap holes 12 of the leveling scraper 1, and then the bucket is moved to the front end of the road surface 13 and lowered to remove the straps (such as Figure 3 shown);

[0028] Next, adjust the two L-shaped guide plates 5 according to the width of the road surface 13. During the adjustment, loosen the positioning screws 9. The T-shaped slider 8 of the L-shaped guide plate 5 is in a loose state. Move the T-shaped slider 8 and the L-shaped guide plate 5 along the sliding groove 4 and make the inner side of the L-shaped guide plate 5 flush with one side of the road surface 13. In this way, the width of the scraping area between the two L-shaped guide plates 5 is adapted to match the road surface 13. After the adjustment, tighten the positioning screws 9 to fix the L-shaped guide plate 5.

[0029] Then, the front end plane of the bucket 16 of the excavator 15 (the bucket adopts a flat slope bucket) is vertically inserted into the slots 3 of the plurality of blocks 2 (such as Figure 4 As shown), then fill the cooling water tank 10 of the spray assembly with water and place it on the bottom plate 7 inside the L-shaped guide plate 5, operate the excavator 15 to move backward along the road surface 13, and the bucket 16 drives the leveling scraper 1 and the L-shaped guide plate 5 to scrape the asphalt material on the road surface 13 flat, and the L-shaped guide plate 5 and the receiving plate 6 on its side can limit the scraped excess material to prevent the excess material from spreading to both sides of the road surface 13, ensuring that the material is always on the inside of the road surface 13, so that the asphalt 14 material scraped on the road surface 13 has good flatness quality, and only needs the excavator 15 to move once to level it, and its leveling efficiency is greatly improved;

[0030] Moreover, during leveling, the cooling water tanks 10 on both sides spray water through the cooling holes to the inner side of the L-shaped guide plate 5 and flow out along the bottom plate 7. The liquid sprayed to the L-shaped guide plate 5 plays a cooling role, avoiding the L-shaped guide plate 5 from being radiated by the high temperature of asphalt and reducing its strength, improving the high temperature resistance and deformation resistance of the L-shaped guide plate 5, ensuring the diffusion of asphalt materials to the outside, and the cooling water tanks 10 also play a counterweight role, ensuring the fit between the bottom plate 7 at the bottom of the L-shaped guide plate 5 and the road surface.

[0031] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
