[0037] Working principle:
[0038] The single-sided bidirectional rotary plow unloader is used for single-sided switching unloading of belt conveyors. The single-sided bidirectional rotary plow unloader is installed at the unloading point of the belt conveyor. Assuming that one side of the belt conveyor is side A and the other side is side B, the electric push rod 14 is in the retracted state at the beginning (electric push rod 14 is at its longest), the plow device 6 is raised, the flat idler roller 7 is in the lowest position, and the plow device 6 is in the unloading position on side A.
[0039] Feeding from side A: Electric push rod 14 retracts (electric push rod 14 becomes shorter), driving torque arm 16 to rotate, swing arm 17 to rotate, connecting rod 18 to rotate, and linkage device 19 to move. Linkage device 19 drives connecting plate 20, flat idler roller 7, and flat idler roller bracket 8 to rise and lift the belt. At the same time, the rotation of linkage device 19 drives rotary drive device and plow device 6 to rotate and press down on the belt conveyor. The belt conveyor is pressed down from up and down, so that the material on it falls to the designated position on side A.
[0040] Switching from A-side to B-side feeding: First, the A-side feeding ends, the electric push rod 14 extends (the electric push rod 14 changes from its shortest to its longest length), driving the torque arm 16 to rotate, the swing arm 17 to rotate, the connecting rod 18 to rotate, and the linkage device 19 to move. The rotation of the linkage device 19 drives the connecting plate 20, the flat idler roller 7, and the flat idler roller bracket 8 to descend and disengage from the belt. At the same time, the rotation of the linkage device 19 drives the rotary drive device and the plow device 6 to rotate and lift upward. The rotary drive part 13 drives the rotary bearing 12 to rotate, and the driven surface of the rotary bearing 12 rotates, driving the plow device 6 to rotate. When it rotates to the B-side unloading position, it stops. The position limit device 5 senses the stop signal given by the sensing block, the rotary drive part 13 stops operating, and the plow device 6 is in the side discharge position; next, the electric push rod 14 retracts (the electric push rod 14 becomes shorter), the power torque arm 16 rotates, the swing arm 17 rotates, the connecting rod 18 rotates, and the linkage device 19 moves. The rotation of the linkage device 19 drives the connecting plate 20 and the flat idler roller 7 and the flat idler roller bracket 8 to rise and lift the belt. At the same time, the rotation of the linkage device 19 drives the rotary drive device and the plow device 6 to rotate and press down on the belt conveyor. The belt conveyor is pressed down from up and down, so that the material on it falls to the designated position on side B.
