Background

The concrete mixing plant, also called concrete mixing plant, is mainly applied to concrete mechanical engineering construction such as concrete mixing and the like. Compared with aggregate metering of a concrete mixing plant, the aggregate metering of the concrete mixing plant has the advantages that four intermediate links are reduced, vertical blanking metering is realized, and the metering time is saved, so that the production efficiency is greatly improved. Under the condition of the same model, the production efficiency of the mixing plant is improved by one third compared with that of the mixing plant.

Chinese patent application publication No. CN102490274A discloses a novel two-step concrete mixing plant and control method thereof, including aggregate bin, oblique belt, weigher, mixer, mixing plant main frame and holding hopper, characterized by that the aggregate weighing hopper of weigher is arranged at the top of mixing plant main frame, the mixer is located below the weigher, holding hopper is located below the mixer, the aggregate bin is placed on the ground, the aggregate bin is connected with the weigher through the oblique belt. The aggregate bin is characterized in that the number of the aggregate weighing hoppers is two, namely a sand weighing hopper and a stone weighing hopper. Aggregate is conveyed into the weighing hopper through the belt by the storage bin, other materials are conveyed into the weighing hopper by the conveying system, the materials are unloaded into the stirring main machine for stirring after the weighing of the materials is finished, and the weighing hopper carries out the next tank weighing after the unloading is finished. The time for mixing starts after all the material has been discharged to the mixer. When the stirring time is up, the concrete is unloaded into the material collecting hopper at one time, the unloading time is up, the unloading door of the stirring machine is closed, meanwhile, the microcomputer judges whether the metering system is finished, the metering system finishes unloading the material into the stirring machine for stirring, the stirring is complete, and the above actions are repeated.
