Description

Technical Field

[0001] The utility model relates to the technical field of scale calibration, in particular to a scale calibration device for concrete production. Background Art

[0002] Scale calibration, also known as scale calibration or scale instrument calibration, refers to the process of checking, adjusting and verifying a scale. Its purpose is to ensure the accuracy and stability of the scale readings under normal use. During the scale calibration process, it may involve adjusting the scale's zero offset, range, sensitivity and other parameters. After a scale has been used for a period of time, errors may occur due to temperature changes, zero drift and other reasons. At this time, scale calibration can eliminate these errors.

[0003] During concrete production, scales are used to weigh the concrete raw materials to maintain the precise proportion of concrete ingredients. At the same time, the precise proportion of ingredients is one of the key factors to ensure the quality of concrete, so the scales need to be regularly maintained and calibrated.

[0004] However, in actual use of the prior art, during the calibration process of the scale used to weigh concrete raw materials, weights are usually used to weigh and calibrate the scale. Since the concrete raw materials weighed by the scale for weighing concrete raw materials are usually heavier, the weights used for weighing and calibrating them are also heavier, which makes it cumbersome and laborious to carry and use the weights for weighing and calibrating one by one, thereby affecting the calibration efficiency of the scale. Utility Model Content
