Technical Field

[0001] The invention relates to the technical field of municipal highway engineering equipment, in particular to an automatic pouring device for municipal asphalt concrete highway pavement construction. Background Art

[0002] Municipal engineering involves the construction of urban infrastructure, including roads, bridges and subways. In my country, the construction of public infrastructure within the planning of cities, towns and villages all belong to municipal engineering. Highway construction is a key part of municipal construction. With the rapid growth of the economy, road construction has also developed rapidly. Municipal highways are mainly divided into cement concrete, asphalt concrete, recycled asphalt concrete and reinforced concrete roads. Among them, asphalt concrete roads have become the most common type due to their wide application. In the construction of asphalt concrete, we will use pouring equipment to pour asphalt or concrete on the road surface.

[0003] The pouring device for road construction is a mechanical equipment used for paving asphalt concrete pavement. The device ensures the smoothness and durability of the road surface by precisely controlling the temperature and flow of asphalt concrete, thereby greatly improving the quality and service life of the road. It can effectively reduce material waste during the construction process, improve construction efficiency, and ensure the economy and environmental protection of highway construction projects.

[0004] Asphalt storage tanks are used as places for mixing concrete. During the mixing process of asphalt concrete, unevenness may occur. Especially when used for a long time or the mixing volume is large, the asphalt concrete at the edges and corners of the tank is difficult to be fully mixed, affecting its performance and quality. The existing solution is to install multiple stirring blades or stirring rods in the asphalt storage tank to stir the asphalt concrete from different angles and positions to improve the uniformity of mixing. However, during the mixing process of asphalt concrete by the current stirring blades, a large amount of asphalt concrete will adhere to the inner wall of the storage tank, resulting in uneven mixing, which in turn affects the use efficiency of the asphalt concrete.

[0032] Working principle: First, the storage tank 2 and the inner tube 6 are formed as one piece. The inner tube 6 can avoid the loss of internal temperature. The material is poured in in equal proportion through the feed port 22. The heating wires on the heating device 7 are distributed between the storage tank 2 and the inner tube 6 to achieve the heating treatment of the internal asphalt concrete. The servo motor 9 is started to drive the rotating rod 14 to rotate at high speed. The multiple stirring blades 21 on the outer wall are driven by the rotating rod 14 to fully stir the middle material. At the same time, the upper and lower ends of the rotating rod 14 are fixed with a cross plate 15 and a cross plate 15. The cross plate 20 and the cross plate 20 are fixed in one piece. At the same time, a plurality of connecting rods 17 are installed between the cross plate 15 and the cross plate 20. The connecting rods 17 rotate through the mutual engagement of the gear 16 and the gear ring 18, and cooperate with the scraper 19 to fully stir and scrape the material inside the storage tank 2 and the material attached to the inner wall. When the material inside the storage tank 2 is stirred, the discharge valve 10 is opened by control to allow the material to flow into the conveying pipe 11, and the spiral blade 13 is driven by starting the servo motor 2 to transport the material horizontally. Then, the asphalt concrete flows into the lower hopper 303 through the conveying pipe 11.

The bottom of the lower hopper 303 is connected to the paving plate 305, and the asphalt concrete is evenly laid on the road surface through the paving plate 305. By starting the vibration motor 306, the dispersion process of the asphalt concrete can be accelerated to improve the laying efficiency. The spring 307 is used to reduce the shaking caused by the vibration, so as to prevent the vibration from directly acting on the mobile frame 5 and generating unnecessary noise. The mobile frame 5 achieves the effect of independent movement through the mutual cooperation of the second wheel 35 and the universal wheel 36. In addition, the mobile frame 5 and the vehicle body 1 are designed to be installed independently. Before installation, the plug-in plate 408 on the top of the mobile frame 5 quickly plugs and positions the entire flat structure when the electromagnet 407 generates suction. When the mobile frame 5 is installed on the left side of the vehicle body 1, the fixing groove 404 on the right side of the fixing plate 403 is aligned with the left side of the top plate of the vehicle body 1 for plugging. At this time, the reinforcing bolt 405 is aligned with the screw hole 406 on the vehicle body 1. Rotate the reinforcing bolt 405 to firmly install the fixing plate 403 on the left side of the vehicle body 1.

[0033] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
