Abstract

The invention provides a powder sampling device which is characterized in that friction is performed by a grinding head at a powder pre-sampling component to obtain ground powder; meanwhile, due to the existence of a sealing mechanism, the ground powder can be prevented from diffusing to air. The sealing mechanism is connected with a ground powder connecting mechanism through a hose; after the ground powder connecting mechanism is started, due to the attractive effect of the ground powder connecting mechanism, the ground powder can enter the ground powder connecting mechanism through the hose. The grinding head can be an annular grinding head specifically. The powder sampling device provided by the embodiment of the invention is easy to carry and convenient to use and has low probability of causing the problem of dust pollution.

Description

technical field [0001] The invention relates to the construction field, in particular to a powder taking device. Background technique [0002] Concrete is one of the most commonly used materials in modern architecture. However, since concrete has been used in civil engineering for one and a half centuries, a large number of reinforced concrete structures have not reached the expected service life due to carbonation, chloride pollution, sulfate attack, and acidic medium corrosion, which has caused large financial losses. Therefore, it is particularly important to carry out grinding sampling and chemical analysis and detection of concrete to detect concrete. [0003] However, the existing methods for obtaining concrete samples are usually to drill holes on site for sampling, and then further grind and sample the samples taken. The existing devices for obtaining concrete samples are poor in portability, inconvenient to use, and easily cause dust pollute. Contents of the inv...
