Description

Technical Field

[0001] The utility model relates to the technical field of construction components of a paver, and more specifically to a material outlet structure of a paver capable of preventing segregation of mixed materials. Background Art

[0002] In the prior art, the phenomenon of uneven coarse and fine aggregate and asphalt content in the mixture during construction is called segregation. Segregation runs through the entire construction process, and is most obvious during paving. During paving, strip segregation is mainly concentrated in the chain box, hanger, and both sides of the paver, which is related to the paver's anti-segregation ability; vertical segregation is mainly manifested in large materials rolling from the gap under the front baffle to the bottom, forming a concentration of large materials that is not easy to lift the core; sheet segregation occurs between the two hangers of the paver, because the arrangement of the spiral feeder blades makes it easy for coarse materials to concentrate in this area, especially when the supply is insufficient during discontinuous paving.

[0003] During the actual operation of the paver, the mixture transported to both sides by the spiral feeder blades falls from between the horizontal and vertical baffles of the paver and is paved on both sides of the road. In this process, firstly, the mixture between the horizontal and vertical baffles cannot be stirred, resulting in uneven mixing of coarse and fine aggregates. The coarse aggregate will fall first due to gravity and gather at the bottom of the road surface, causing segregation. At the same time, due to the lack of stirring, temperature differences are likely to occur in the upper and lower layers of the mixture, causing further segregation. Secondly, there is no blocking structure designed under the discharge port, resulting in the mixture being directly slanted and spread onto the road surface. The paving and transportation is not smooth enough, which will also cause segregation. The above two problems will affect the paving quality on both sides of the road. Utility Model Content

[0004] The purpose of the utility model is to provide a paver discharge port structure which can prevent the segregation of the mixture. The discharge port structure can stir the mixture in the area between the horizontal and longitudinal baffles on both sides of the paver, thereby improving the coarseness and uniformity of the mixture at the discharge port positions on both sides, reducing the temperature difference between the upper and lower layers, and at the same time improving the smoothness of paving and conveying, thereby preventing segregation to a certain extent and ensuring the quality of paving construction.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
