A load verification method for concrete batching scale

Abstract

The invention discloses a method for calibrating the load of a concrete batching scale. Equipment is installed and fixed, so that supporting points are accurate, the load is consistent with the gravity direction, uniform and balanced, after the purpose of accurate calibrating is achieved, a data acquisition and processing device is connected with a computer, the intelligent control is realized through software in the computer, then the concrete batching scale is calibrated, the measured data is transmitted to the computer for data comparison and verification by a weight verification method, sothat the problems of time consuming, labor-consuming and excessively high cost of an existing concrete batching scale can be solved, the working efficiency and metering accuracy can be improved, andhigher social and economic benefits can be brought into play.

Description

technical field [0001] The invention relates to a method for verifying the load of a concrete batching scale. Background technique [0002] Batching scale is a relatively special weighing instrument, which is a weighing instrument that will pre-specify the mass ratio and perform batching and measurement of several substances in the object to be weighed. The concrete batching scale synthesizes different bulk materials (concrete raw materials: aggregate, cement, water and admixtures, etc.) into concrete with a predetermined quality and fixed proportion through automatic weighing. The weighing principle of the batching scale is to use the gravity acting on the weighing hopper to determine the mass of the object, that is, the force converted from the mass of the material is measured and calculated by the measuring device, and then the measurement value is displayed in mass units. [0003] The concrete batching scale mainly includes one or more weighing units. Each weighing unit...

Problems solved by technology

It takes at least 300 times for static verification of a 25kg standard weight up and down at a time; for dynamic verification, if each scale is to check a common loading point, calculated on the basis of 8 scales, 80 times of materials need to be loaded. A lot of manpower and material resources

[0004] To sum up, with the rapid development of the economy, enterprises and institutions have higher and higher requirements for the verification of concrete batching scales. The traditional standard method is difficult to achieve full-scale verification, and it is labor-intensive.
