[0048] Example 1
[0049] like Figures 1-3 The concrete sampling device shown includes a pre-storage hopper 1 and a sampling hopper 4; a connecting port 7 is provided on one side of the pre-storage hopper 1, the height of the connecting port 7 is at 2 / 3 of the vertical height of the pre-storage hopper 1, and the minimum size of the connecting port 7 is not less than 16cm; the sampling hopper 4 has an angle of 30°~40° with the vertical direction, the sampling hopper 4 has a hollow cuboid structure, and the volume is 22~25L.

The specific usage method is as follows:
[0051] (1) When no sampling is required, cylinders A2 and B5 are used to control the first movable door 3 and the second movable door 6 to rotate to open the discharge port and the material collection port respectively. After the concrete is mixed in the mixer, it is unloaded and falls into the pre-storage hopper 1 of the concrete sampling device. Since the discharge port at the bottom of the pre-storage hopper 1 is open, the concrete continues to flow from the discharge port into the concrete truck. It will not accumulate and will not enter the material collection hopper 4 through the side connection port 7.
[0052] (2) When sampling is required, cylinders A2 and B5 are used to control the first movable door 3 and the second movable door 6 to close the discharge port and the collection port respectively; when concrete is discharged from the mixer, since the bottom of the pre-storage hopper 1 is closed, the concrete gradually accumulates in the pre-storage hopper 1. When it overflows to the connecting port 7 of the pre-storage hopper 1, due to the principle of communicating vessels, the concrete will flow into the collection hopper 4 and gradually fill the collection hopper 4 as the amount of concrete increases.
[0053] (3) When the mixer finishes unloading for about 3 seconds, the first arc plate 3.1 is rotated by the cylinder A2 to open the discharge port and let all the concrete in the pre-stored hopper 1 flow into the concrete truck.
[0054] (4) The cylinder B5 controls the second arc plate 6.1 to rotate until the material taking port is opened, and the concrete in the material taking hopper 4 flows into the corresponding container to realize concrete sampling.
