Referring to fig. 1 and 2, an automatic sintered ore sampler 100 includes a support 110, a hollow shaft 120, and a sampling hopper 130. The hollow shaft 120 is rotatably mounted on the bracket 110, the hollow shaft 120 has a cavity 122 (see fig. 3), and the material taking hopper 130 is mounted on the side wall 121 of the hollow shaft and is communicated with the cavity 122. During the rotation of the hollow shaft 120 along the axial direction thereof, the material taking hopper 130 can pass through the falling trajectory of the material 300, and the material 300 enters the cavity 122 from the material taking hopper 130, completing the sampling of the material 300.

For example, the material cross-sectional profile 310 is rectangular, and the farthest end of the material cross-sectional profile 310 from the axis of the hollow shaft 120 is the outer corner B of the rectangle; the most proximal end of the material cross-sectional profile 310 from the axis of the hollow shaft 120 is the distance of the fourth profile 314 from the axis of the hollow shaft 120.

the rotary driving device is arranged on the support and can drive the hollow shaft to rotate around the axis line of the hollow shaft.
5. The automatic sintered ore sampling machine as claimed in claim 4, wherein the rotation driving means comprises a motor mounted to the support frame, the motor being capable of driving the hollow shaft to rotate.
6. The automatic sintered ore sampling machine according to claim 1, wherein the hollow shaft is obliquely arranged toward a side close to the material.
7. The automatic sintered ore sampling machine according to claim 1, wherein the support is a dust cover of a material falling point, and the hollow shaft and the take-out hopper are arranged inside the dust cover.
8. The automatic sintered ore sampling machine as claimed in claim 1, wherein the upper part of the material taking hopper is provided with a receiving port, and when the material taking hopper passes through the falling track of the material, the cross-sectional profile of the material can be positioned within the profile of the receiving port.
9. An automatic sintered ore sampling machine as claimed in claim 8 wherein the receiving port includes an annular region arranged concentrically with the hollow shaft, when the take-off hopper passes the trajectory of the falling material:
the distance from the outer arc line of the annular area to the axis of the hollow shaft is D1, the distance from the farthest end of the cross-sectional profile of the material to the axis of the hollow shaft is D2, and D1 is more than D2;
the distance between the inner arc line of the annular area and the axis of the hollow shaft is D3, the distance between the nearest end of the cross-sectional profile of the material and the axis of the hollow shaft is D4, and D3 is less than D4.
10. The automatic sintered ore sampler of claim 9 wherein the hopper has a first side wall and a second side wall spaced apart in the direction of rotation of the hollow shaft and forming two radial contours of the annular region;
the two sides of the cross section profile of the material in the rotating direction of the hollow shaft are respectively provided with a first contour line and a second contour line;
when the material taking hopper enters a falling track of the material, the second side wall is in contact with the material and is parallel to the first contour line;
when the material taking hopper leaves the falling track of the material, the first side wall leaves the material and is parallel to the second contour line.
