[0024] Example 1

[0025] Please refer to the accompanying drawings Figures 1-2The application provides a concrete slurry sampling device, which comprises a sampling cylinder 1, a piston 2, a connecting rod 3, a handle 4 and a vibrator 5, the sampling cylinder 1 is rotationally connected with the handle 4, the piston 2 is arranged in the sampling cylinder 1, the piston 2 is connected with the connecting rod 3, and the vibrator 5 is connected with the sampling cylinder 1. When sampling, the piston 2 is pushed downwards through the connecting rod 3, so that the piston 2 is leveled with the bottom of the sampling cylinder 1 or slightly protrudes from the sampling cylinder 1. A worker holds the handle 4, inserts the sampling cylinder 1 into the concrete slurry at a preset depth, then pulls the connecting rod 3 upwards, and the concrete slurry sample is sucked into the sampling cylinder 1 under the action of the piston 2, then the sampling cylinder is taken out of the concrete slurry. During the process of inserting the sampling cylinder 1 into the concrete slurry, the vibrator 5 is turned on, the vibrator 5 is located above and / or below the handle 4, the position of the handle 4 is stabilized, then the sampling cylinder 1 is shaken and swings with the handle 4 as the center, the vibration swing amplitude of the bottom of the sampling cylinder 1 is large, so that the worker can easily insert the sampling cylinder 1 into a position with a larger depth for sampling.
