[0002] Concrete is used in construction projects. Concrete is a building material composed of cementitious materials, aggregates, water, and other admixtures mixed in a specific ratio. It is widely used in civil engineering projects, such as the construction of bridges, houses, and roads. During the concrete production and processing, sampling tests are generally conducted to detect quality parameters such as water content and slump. Sampling devices are typically used in this process. Currently, conventional sampling devices are containers with an opening at the top, which are inserted into the concrete. Some improved technologies use tubular containers with openings on the bottom side wall. However, because the opening is on the side, the concrete is not poured completely, leaving residue on the inner wall of the container after each sampling, which is difficult to clean. Therefore, this invention provides a concrete quality testing sampling device to solve the above problems. Summary of the Invention
