The working principle of the aggregate batching system of the concrete mixing ship is as follows: when the left and right wire stirring main machines 26A and 26B need to carry out normal aggregate batching, the left and right wire transfer conveyer belts 45a and 45B are positively rotated, aggregates in the four left and right wire aggregate cabins 30a and 30B correspondingly fall into the four left and right wire batching measuring hoppers 41a and 41B for measuring one by one, when a measured value reaches a set proportioning value, the aggregates are sequentially sent to the left and right wire bending and head-picking conveyer belts 43a and 43B and the left and right wire transfer conveyer belts 45a and 45B one by the left and right wire aggregate conveyer belts 42a and 42B, are sent to the left and right wire elevators 44A and 44B one by the left and right wire elevators 44A and 44B, and then are sent to the left and right wire aggregate transition storage cabins 24A and 24B one by the left and right wire transition conveying conveyer belts 45a and 45B, and enter the left and right wire transition storage cabins 24A and 24B blanking openings one by one, The concrete is stirred in the right-hand stirring main machines 26A and 26B. When the left line stirring main machine 26A breaks down, the left line transferring conveyor belt 45a rotates reversely, aggregates in the four left line aggregate chambers 30a are sequentially conveyed to the left line transferring conveyor belt 45a through the left line aggregate conveyor belt 42a and the left line bending head-picking conveyor belt 43a, conveyed to the right line elevator 44B through the left line transferring conveyor belt 45a, and then conveyed to the right line aggregate transition storage chamber 24B through the right line elevator 44B, so that the right line stirring main machine 26B consumes the aggregates in the four left line aggregate chambers 30a, and the right line stirring main machine 26B can also consume the aggregates in the four right line aggregate chambers 30B, thereby realizing the balanced consumption of the left line aggregate chambers and the right line aggregate chambers and realizing the continuous production of concrete. Similarly, when the right stirring main machine 26B fails, the right transfer conveyor belt 45B rotates reversely, aggregates in the four right aggregate chambers 30B are sequentially conveyed to the right transfer conveyor belt 45B by the right aggregate conveyor belt 42B and the right bending and head-picking conveyor belt 33B, conveyed to the left elevator 44A by the right transfer conveyor belt 45B, and then conveyed to the left aggregate transition storage chamber 24A by the left elevator 44A, the aggregates in the four right aggregate chambers 30B are consumed by the left stirring main machine 26A, and the aggregates in the four left aggregate chambers 30a can be consumed by the left stirring main machine 26A, so that balanced consumption of the left and right aggregate chambers is realized, and continuous production of concrete can be realized.
