Description

Technical Field

[0001] The utility model relates to the technical field of regenerated asphalt concrete preparation, in particular to a regenerated asphalt concrete preparation device. Background Art

[0002] At present, many highways in my country have entered the period of medium and major repairs. The design life of general asphalt pavement is 15-20 years. A large number of asphalt pavements need to be renovated every year, so a large amount of waste asphalt materials are generated every year. If these waste materials are not recycled, they will not only waste a lot of resources, but also cause serious pollution to the environment. Therefore, promoting and applying waste material recycling technology and equipment is an important measure to save energy and reduce consumption, which can minimize the consumption of energy and raw materials and achieve a "win-win" goal of economy, resources and environment. Recycled asphalt concrete is an environmentally friendly material obtained by crushing, screening and mixing waste asphalt pavement materials.

[0003] For example, the prior art publication number CN215196523U is a quantitative proportioning mixing device for the production of recycled asphalt concrete. The utility model connects a metering box and a conveyor belt. The raw materials that need to be proportioned are poured into the feed port. Since the capacity of the inner box arranged inside the metering box is consistent, the raw materials can be effectively weighed. The conveyor belt can be moved by rotating the rotating rod, so that the raw materials in the inner box are transported to the inside of the outer shell. In this way, the quantity weighed each time can be consistent, avoiding the tediousness of manual weighing.

[0004] However, the above-mentioned prior art still has the following problems when in use: when using a metering box to measure the recycled asphalt concrete material, since the metering box is located at a high position of the mixing body, it is time-consuming and laborious for the staff to load the material, and the asphalt concrete material is easy to spill and cause waste. Based on this, the utility model provides a recycled asphalt concrete preparation device that can automatically lift and load materials. Utility Model Content
