Description

Automatic sampling device for concrete powder Technical Field The utility model relates to the technical field of concrete powder sampling, in particular to an automatic concrete powder sampling device. Background The concrete powder is a powdery mixture composed of cementing materials, mineral admixture, functional admixture and the like, is prepared by grinding and homogenizing processes, has high specific surface area and good dispersibility, is widely applied to projects such as buildings, bridges, roads and the like, is used as a cementing main body of concrete, and directly determines the mechanical property and durability of the concrete in quality. Through retrieval, the Chinese patent publication No. CN211347513U is an automatic powder sampling device for concrete, which comprises a sampling pipeline, one end of the sampling pipeline is communicated with a feed pipe arranged on a powder storage tank, the other end of the sampling pipeline is connected with a sampling bag, a manual valve and an electric control valve are arranged on the sampling pipeline, and a time control switch is correspondingly arranged on the electric control valve, so that the problems that the traditional powder sampling device is small in sampling range, the sample is not representative, partial bad suppliers are charged in order, unqualified powder is filled outside the working range of a sampling rod, engineering quality is seriously endangered and the like are solved.
