AI Technical Summary

Technical Problem

The existing concrete sampling device cannot separate the concrete core from its root during drilling and sampling, and requires a secondary operation by the operator. The concrete output lacks anti-solidification capability, which affects the detection results and has a large operating energy consumption.

Method used

A concrete sampling device including a spherical sample storage box, a bidirectional swing mechanism, a piston sampling pump and a telescopic sampling tube is designed. Keep the concrete samples in a flow state through a bidirectional swing mechanism to prevent solidification; piston sampling pumps and telescopic sampling tubes realize automated sampling and length adjustment, ensuring rapid collection and storage of concrete samples.

Benefits of technology

It realizes the rapid collection and storage of concrete samples in a short time, prevents solidification, reduces operating energy consumption, and improves sampling efficiency and accuracy.
