Problems solved by technology

[0004] However, during the production process of the asphalt mixing plant with the existing structure, due to problems such as untimely feeding of cold material or mismatching of aggregate particles, there are often problems of material shortage and overflow in the hot material silo, which wastes energy for customers and seriously affects the production capacity of the equipment.
At present, to solve the problem of material shortage and overflow of hot aggregate, it mainly relies on the operator's on-site experience and manual deployment, which requires high skill level of the operator and high labor intensity

Abstract

The invention provides an automatic batching method of an asphalt mixing station, the asphalt mixing station comprises N cold material silos and N hot material silos, 1st cold bunker, the average particle size of aggregate stored in the 1-th cold silo, the 2-th cold silo...the N-th cold silo is increased in turn, The average particle size of aggregates stored in the 1-th cold silo, the 2-th cold silo...the N-th hot material bin is increased in turn, the first cold material bin corresponds to the first hot material bin, and the second cold material bin corresponds to the second hot material bin. The automatic batching method comprises the following steps: step 102: the storage amount of each hot material bin is acquired; Step 104: When the storage quantity of the i-th hot material bin is lower than the first preset value, the discharge speed of the i-th cold material bin is increased, and when the storage quantity of the i-th hot material bin is higher than the second preset value, thedischarge speed of the i-th cold material bin is decreased, wherein, i is selected from An integer of 1-N, the first preset value being smaller than the second preset value. The invention additionallyprovides an automatic batching system of an asphalt mixing station and an asphalt mixing station.
