The invention discloses an expressway asphalt concrete feeding device and a mixing system thereof, and relates to the technical field of asphalt concrete mixing, the expressway asphalt concrete feeding device comprises a main shell, a top cover plate is mounted at the top of the main shell, a sliding cover is slidably mounted in the top cover plate, and a movable hole is formed in the top of the top cover plate; and movable limiting columns are movably mounted in the movable holes. During use, aggregate and asphalt are put into the main shell, when the aggregate passes through the filter screen plate, a small part of aggregate with large size can be intercepted, and when the main rotating column rotates, the crushing cutter overcomes the tension of the tension spring to extend outwards under the action of centrifugal force; and then the aggregate with the large size above the filter screen plate is impacted through the multiple crushing cutters to be crushed and falls into the position below the filter screen plate to be added and mixed, the situation that due to the aggregate with the large size, local mixing of the asphalt concrete is uneven is avoided, and the stability of the asphalt concrete is guaranteed.
本发明公开了一种高速公路沥青混凝土上料装置及其混合系统，涉及到沥青混凝土混合技术领域，包括主壳体，主壳体的顶部安装有顶盖板，所述顶盖板内滑动安装有有滑动盖，顶盖板的顶部开设有活动孔，所述活动孔内活动安装有活动限位柱。使用时，将骨料与沥青投入主壳体内，骨料经过过滤网板时，小部分体积较大的骨料则会被截留，当主转动柱转动时，破碎刀具受到离心力作用，克服拉簧的拉力向外伸出，随后通过多个破碎刀具对过滤网板上方的体积较大的骨料进行撞击使骨料破碎，并落入过滤网板下方加入混合，避免较大体积的骨料导致沥青混凝土局部混合不均匀，保证了沥青混凝土的稳定性。
