Description

Technical Field

[0001] The utility model relates to the technical field of asphalt transportation, in particular to a feeding device for pervious asphalt construction. Background Technique

[0002] In recent years, the pervious pavement engineering projects for sponge city construction are in full swing, and many ecological and environmental protection greenways have been laid. These environmental protection greenways are exactly paved with pervious asphalt, and pervious asphalt has a wide range of applications in the fields of road repair and so on. At present, the construction of pervious asphalt is mostly carried out by laying and compacting asphalt in a high-temperature environment. After the pervious asphalt cools, it hardens and forms a road surface. During the construction process of pervious asphalt, it is necessary to frequently add high-temperature pervious asphalt into the paver, and a feeding device is required for this process;

[0003] In the prior art, the content of the Chinese utility model with the publication number: CN218478995U discloses a feeding device for pervious asphalt construction, including a feeding frame. A feeding hopper is fixedly arranged at the top of the feeding frame, a feeding conveying cylinder is fixedly arranged in the middle of the feeding frame, a driving motor is fixedly installed at the bottom of the feeding conveying cylinder, and a pushing auger located inside the feeding conveying cylinder is fixedly installed at the output end of the driving motor. This feeding device for pervious asphalt construction in the utility model uses the auger pushing method to carry out the feeding work on the pervious asphalt material, and can move flexibly with the movement of the asphalt laying equipment. The operation and use are simple and convenient, so as to effectively improve the feeding efficiency of asphalt. Heating elements are arranged at the bottom of the feeding hopper and inside the feeding conveying cylinder, and are combined with a heat preservation sleeve for heat preservation and heat insulation, so as to effectively reduce the heat loss of high-temperature pervious asphalt during the feeding and conveying process, thereby reducing the probability of pervious asphalt cooling and solidifying, making the feeding process of the feeding device stable and reliable, and not easy to be blocked;

[0004] In the above technical solution, the conveying efficiency of the pervious asphalt material is improved, and the solidification of the asphalt material is avoided by heating. However, in the construction feeding of this technical solution, the supporting force area in contact with the ground through multiple universal wheels is small, which may cause the position of the feeding frame to shift due to the vibration of the driving motor during the conveying of the asphalt material. Furthermore, it is necessary for construction workers to manually support to stabilize the material conveying effect, increasing the labor intensity of the construction workers. Therefore, we need to propose a feeding device for pervious asphalt construction. Content of the Utility Model
