By providing the barrel 1, the support shaft 2, the adjusting handle 3, the movable block 4, the mounting block 5, the connecting hole 6, the discharge port 7, the support block 8, the positioning block 9 and the sampling box 10, it is convenient to drive the movable block 4 to rotate, so that the spiral distribution of the movable block 4 makes it possible to drive the mixed sand to move and then take it out, which improves the convenience of operation, solves the time-consuming and labor-intensive problem caused by the cumbersome operation during sampling, and thus meets people's work needs, and is worthy of popularization and use.

[0020] Furthermore, the adjustment handle 3 is in a "cross"-shaped structure, and the adjustment handle 3 is rotatably connected to the barrel 1 through the support shaft 2, which facilitates the rotation of the support shaft 2.

[0021] Furthermore, the movable block 4 is of a threaded structure, and one end of the movable block 4 extends out of the interior of the barrel 1, which facilitates the support shaft 2 to drive the movable block 4 to rotate, so that the movable block 4 drives the casting sand to move.

[0022] Furthermore, the outer wall of the mounting block 5 is provided with connecting holes 6, and the connecting holes 6 are distributed at equal angles along the axial center line of the mounting block 5, which facilitates the connection between the mounting block 5 and the sampling pipe flange of the sand mixing device after installing bolts through the connecting holes 6.
