After the cover 500 is adjusted, the handle 744 is pushed to drive the pin 743 to move close to the positioning slot 741 along the length direction of the through hole 742, so that the pin 743 is engaged with the positioning slot 741 to fix the sliding block 720.

At this time, since the restoring spring 745 is not subjected to the outward pulling force, the elastic potential energy thereof is released, so as to generate a force for the latch 743 to move close to the positioning groove 741, thereby further improving the fixing firmness of the sliding block 720.

After the apron 500 is adjusted and is accomplished, the pilot valve 210 is opened to the laboratory technician, and concrete mixture flows down along discharging pipe 200 length direction, and concrete mixture in the flow can flow into on the sampling plate 400 from sample connection 300, and the laboratory technician of being convenient for takes a sample.

After the laboratory technician sample is accomplished, start drive arrangement 700, drive arrangement 700 drive apron 500 rotates to make the closed plate 520 orientation that sets up with 500 an organic whole of apron rotate towards the one side that is close to sample connection 300, thereby make sample connection 300 close, concrete mixture no longer flows into sampling plate 400 from sample connection 300 on, prevents that the ejection of compact of concrete mixture is influenced in the existence of sample connection 300, improves the stability of the ejection of compact of concrete mixture.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
