Automatic metering device for premixed concrete aggregate and operation method

Abstract

The invention relates to the field of concrete construction, in particular to an automatic metering device for a premixed concrete aggregate and an operation method. The construction steps are as follows: concrete material transportation, hopper feeding, hopper quality measurement, concrete mixing material quality control, mixing bin feeding, mixing bin quality monitoring, mixing bin water contentmonitoring, and concrete mixing and conveying, wherein the weight of a hopper and the weight of a concrete mixing bin are measured through a mass sensor, pressure changes of the inner side wall of the hopper and the inner side wall of the concrete mixing bin are measured through a pressure sensor, and therefore the feeding amount of the mixing bin is calculated; the water content of concrete in the mixing bin is measured through a water content sensor arranged on the side wall of the concrete mixing bin, and the water content is fed back to a computer through wireless signal transmission to control water inflow; and intelligent and accurate feeding of premixed concrete can be achieved, high-quality premixed concrete is produced, the labor cost is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of concrete construction, and more particularly relates to an automatic metering device and operation method for ready-mixed concrete aggregates. Background technique [0002] Ready-mixed concrete is made by mixing aggregate sandstone, cementitious material cement, admixtures and water in a concrete mixing station according to a certain mix ratio, and then transported to the construction site for direct concrete pouring. [0003] At present, the concrete ready-mixing station is mainly to manually control the mixing ratio of the materials added to the concrete mixing bin, but this method is prone to some deviations in the mixing ratio, which makes the mixing ratio of the concrete materials different from the laboratory, which affects the ready-mixed concrete. At the same time, the whole process of manual control of concrete mixing will consume a lot of manpower and material resources, and the work efficiency is low, so...

[0003] At present, the concrete ready-mixing station is mainly to manually control the mixing ratio of the materials added to the concrete mixing bin, but this method is prone to some deviations in the mixing ratio, which makes the mixing ratio of the concrete materials different from the laboratory, which affects the ready-mixed concrete. At the same time, the whole process of manual control of concrete mixing will consume a lot of manpower and material resources, and the work efficiency is low, sometimes it is difficult to meet the demand for the outbound volume of ready-mixed concrete
