[0002] Factory-mixed hot recycling means that the old asphalt pavement is excavated and transported back to the mixing plant, and then crushed centrally. According to the quality requirements of different levels of the road surface, the mix design is carried out to determine the addition ratio of the old asphalt mixture. The regeneration agent, new asphalt material, new aggregate, etc. are remixed into a new mixture in a mixer in a certain proportion, thereby obtaining excellent recycled asphalt concrete and paving it into a recycled asphalt pavement.

[0003] A Chinese patent application CN106012764A discloses a batching machine for hot recycled asphalt milling material in an asphalt plant. The key points of its technical solution are: by setting and controlling the transmission speed of the belt scale, the proportion of milling material addition can be intelligently adjusted; the motor shaft of the vibration device is connected to the vibration beam, the amplitude generated is large, and the pneumatic arch breaking device and the vibration beam work together to achieve obvious arch breaking effect, which effectively solves the problem of material blockage in the batching machine.

Since most batching machines lack an anti-blocking structure and some raw materials are sticky, they are likely to stick to the inner surface of the funnel and block the funnel when flowing in the funnel. Therefore, in view of the above problems, a batching machine for mixing hot recycled asphalt milling materials in an asphalt plant is proposed. Utility Model Content
