AI Technical Summary
Most existing concrete sampling devices can only sample the surface concrete. During the process of filling and filling the test block mold, more concrete is likely to remain inside the sampling device.
A sampler for concrete production is designed, including a round rod, spiral groove, conical shell and scraper that can move up and down. By pushing the round rod and conical shell, the concrete spiral downwards, and the scraper scrapes the inner wall of the sampling tube. Concrete avoids residue and facilitates top cover removal and cleaning.
