Background

The construction of domestic infrastructure is leaps and bounds, the dosage of powdery materials such as cement, fly ash and mineral powder is large, and the arrangement of commercial cement concrete mixing plants is wide. Taking cement as an example, a cement plant generally sets a lot number every 2000 tons of cement, and materials leaving the plant every day may have several lot numbers. The test and detection of the quality of the approach materials are indispensable links for the material quality control in the building industry. Sampling is a necessary step before testing. The traditional method is that when powder materials are fed into a field in each car, a rod-shaped sampler is used for exploring from the top of a semi-trailer tank car, and the sampling is time-consuming. Another method is that a metal cover below a concrete batching motor is opened from an overhaul platform of the powder tank, at least 2 persons are needed for cooperation in sampling operation, the sampling is more time-consuming, or a large amount of powder materials are obliquely discharged from the tank. Moreover, for the powder with long standing time, the powder needs to be rechecked, and a metal cover below the batching motor needs to be opened from the maintenance platform for sampling. In this case, the bolt may rust and may not be opened. This causes a certain trouble in the sampling work before the test.
