MA WENXIA / WANG HONG / TAO WENCHAO / HAN JIANJIE

The invention relates to the technical field of constructional engineering, and concretely to an asphalt filling head for road maintenance and a road repairing device are provided. The oil sprayer isrotationally connected to the bottom end of the accommodating cylinder; the containing barrel is of a cylindrical structure. An oil inlet and an oil outlet are formed in the upper end and the lower end respectively. The top of the oil sprayer penetrates through an oil outlet hole in the bottom of the containing barrel, a storage cavity is formed in the middle section of the interior of the oil sprayer, oil spraying holes used for spraying asphalt are evenly formed in the bottom end of the oil sprayer, the oil spraying holes are arranged in a divergent mode, and the top ends of the oil sprayingholes are all located in the storage cavity. Asphalt is uniformly sprayed out through a plurality of divergent oil spraying holes in the bottom end of the oil sprayer, and the oil sprayer is driven to rotate through structures such as the servo motor and the positioning wheel disc, so that the pouring area is enlarged, and the pouring quality of the asphalt is improved.

本发明涉及建筑工程技术领域，具体为一种公路养护用沥青填充头及公路修补装置，容纳筒和转动连接在容纳筒底端的喷油器，所述容纳筒为圆筒状结构，其上下两端分别开设有进油孔和出油孔，所述喷油器的顶部贯穿在容纳筒底部的出油孔内，且喷油器的内部中段开设有储存空腔，喷油器的底端均匀开设有用于喷洒沥青的喷油孔，所述喷油孔呈发散状排列，且喷油孔的顶端均位于储存空腔内。本发明通过喷油器底端的呈发散状的众多喷油孔将沥青均匀喷出，并通过伺服电机和定位轮盘等结构带动喷油器旋转从而扩大浇筑面积，有利于提高沥青的浇筑质量。
