It is understood that the conveyor belt 200 may be configured as a belt.
In the process of transporting the coal mine, the coal mine is driven by the conveyor belt 200 above the first corner roller 130 to turn and transport, when the coal mine moves to the position of the second corner roller 140, the coal mine is thrown out from the conveyor belt 200 at the position of the second corner roller 140 under the action of gravity and falls on the conveyor belt 200 above the axis of the first reversing roller 170 along the parabolic track, and along with the continuous transportation of the conveyor belt 200, the coal mine is thrown out from the conveyor belt 200 at the position of the first reversing roller 170 and falls on the preset position along the parabolic track.
In this embodiment, the middle portion of the first corner roller 130 is configured to rotate around a first axis to adapt to different turning angles, where the first axis is perpendicular to the plane where the frame 100 is located, specifically, as shown in fig. 4, when the first corner roller 130 rotates in a clockwise direction, an included angle between the conveying belt 200 on the second corner roller 140 and the conveying belt 200 on the third reversing roller 190 becomes larger, so that a larger turning angle can be adapted; when the first corner roller 130 rotates in the counterclockwise direction, the angle between the conveyor belt 200 on the second corner roller 140 and the conveyor belt 200 on the third reversing roller 190 becomes smaller, so that a smaller turning angle can be adapted.
In this embodiment, the belt conveyor for coal mine is configured to further include a rotating mechanism configured to rotate the first corner roller 130 about the first axis.
