[0027] The mounting base 3 includes a base 31, a limiting plate 32, a movable plate 33 and a support block 34. The bottom surface of the base 31 is provided with a limiting plate 32, the bottom surface of the base 31 is provided with a movable plate 33 connected to the electric push rod 2, and the top surface of the base 31 is provided with a support block 34. There are multiple support blocks 34. The support block 34 is located below the sampling plate 4. A pressure sensor is provided inside the support block 34 to obtain the amount of aggregate passing above the sampling plate 4, so as to sample after the aggregate delivery reaches the threshold, thereby facilitating the improvement of the representativeness of the aggregate sampling;

[0028] In this embodiment, the mounting seat 3 and the sampling plate 4 are arranged in an inclined manner as a whole, and a V-shaped chute is formed on the top surface of the sampling plate 4. The V-shaped chute formed on the top surface of the sampling plate 4 facilitates the sampling plate 4 to guide the aggregate into the guide tube 6 when sampling is required;

[0036] The implementation principle of the second embodiment is: when the sampling plate 4 does not need to sample aggregate, the blocking plate 51 will block the opening of the guide tube 6 to prevent aggregate from accidentally entering. When the sampling plate 4 samples aggregate, the sampling plate 4 will become inclined, and the sampling plate 4 will push the blocking plate 51 downward through the elastic strip 52 to open the guide tube 6, so that the aggregate can enter the sampling cylinder 7 from the guide tube 6.
