Concrete aggregate automatic bin-searching and feeding system

Abstract

The invention discloses a concrete aggregate automatic bin-searching and feeding system. The concrete aggregate automatic bin-searching and feeding system comprises an aggregate raw material system, aconcrete production system, a belt conveyor transportation system and a control system; the aggregate raw material system comprises storage yards for each raw material with feeders and discharge conveyor belts distributed at the outlet ends; the belt conveyor transportation system comprises a discharge belt conveyor and a long-distance belt conveyor; and the concrete production system comprises aconcrete production device and a storage system, the storage system comprises raw material bins arranged according to the needs of concrete production, and movable material distribution trolleys arecorrespondingly arranged at the tops of the raw material bins. According to the concrete aggregate automatic bin-searching and feeding system, based on the combination of a sensing technology and a PLC control technology, the aggregate transportation amount, the aggregate bin material level, the automatic analyzing and controlling replenishment amount, the replenishment time and the replenishmentsequence are collected, the feeders automatically switch the feeding variety, the material distribution trolleys automatically search bins and replenish materials, the continuous transportation of multi-level aggregate from the aggregate yards to the aggregate storage bins is achieved, and purposes of optimizing the control of a replenishment system and improving the control level are achieved.

Description

technical field [0001] The invention relates to a system for automatically finding bins and feeding concrete aggregates and an operation control method thereof, which is especially suitable for long-distance belt conveyors to transport various graded concrete aggregates, and belongs to the field of mechanical engineering and automation. Background technique [0002] In large-scale concrete production systems, the amount of sand and gravel aggregates is large, and there are many types of aggregate grading. Aggregate replenishment is the key link to realize large-scale continuous production of the system. Generally, belt conveyors are used to transport aggregates to realize the production of sand and gravel aggregates to concrete. The product is fully mechanized and automatically controlled. [0003] Usually, the aggregate storage silo of the concrete production system is far away from the sand and gravel system, and the aggregate of sand and gravel needs to be transported for...

Problems solved by technology

[0004] The degree of automation is not high. The control of the aggregate level and replenishment volume of the aggregate bin in the concrete system is done manually. The operating personnel must patrol and monitor the material level in each aggregate bin, and carry out aggregate replenishment according to the position of the bin.

[0005] In order to avoid mixed silos, the next aggregate can only be transported after one kind of aggregate replenishment is completed, and the continuous conveying of aggregates cannot be real
