Description

Technical Field

[0001] The utility model relates to the technical field of concrete sampling, in particular to a concrete sampling device. Background Art

[0002] The performance status of fresh concrete directly affects the processes of mixing, transportation, pumping, pouring and molding of concrete. The workability of fresh concrete is one of the most important properties of fresh concrete. Fresh concrete needs to be sampled for testing after mixing. The existing method of sampling fresh concrete is to manually shovel out concrete samples with a shovel, and then use the shovel to transfer them to the sampling and testing equipment.

[0003] The existing Chinese utility model patent with reference announcement number: CN219200949U discloses a concrete sampling device. The utility model includes a sampling piece and a plugging piece. The sampling piece includes a sampling barrel, the bottom end of the sampling barrel is open, and the outer circumferential surface of the sampling barrel is horizontally fixed with a hole plate at the top and bottom, and the plugging piece includes a sealing plug, which is movably plugged into the open end of the sampling barrel, and the two sides of the sealing plug are horizontally fixed with connecting plates, and the connecting plates on both sides of the sealing plug are vertically provided with plug rods, and the plug rods slide through and are plugged into the hole plates at the upper and lower ends of the sampling barrel, and the bottom end of the plug rod is fixedly connected to the connecting plate. The utility model overcomes the existing sampling method of using a shovel to collect and transport concrete, which cannot collect concrete samples of different depths, and lacks a special sampling tool during sampling. The concrete samples collected in the later transportation are prone to falling and loss, which affects the sampling range and the sampling volume after sampling.

[0004] Although the above-mentioned concrete sampling device solves the problem of concrete samples falling and being lost, which affects the sampling range and the sampling volume after sampling, the sealing piece is connected to the sampling piece through an insertion rod, and the insertion rod and the screw rod both have a certain length, resulting in a large storage space occupied by the sampling device, reducing the efficiency of the later transportation of concrete samples, and the sampling cylinder is divided into two cylinder structures for connection and use, which causes concrete water leakage at the connection point, affecting the use effect of the concrete sampling tool.
